Abstract

A study on the Subsurface groundwater discharge (SGD) in the coastal Cuddalore region of south east India has been carried out. Measurement of surface water Radon, Water level, Electrical Conductivity (EC) and pH for a total of twenty four hours, by hourly interval the measurement has been calculated and promote correlated with tidal values calculated by WX Tide 32 software. The SGD measurements were made by using a modified seepage meter. The study reveals a match with water level variation and tide with minor variation due to influx of surface water. Saline discharges, fresh groundwater discharges and surface water mixing processes were identified along the coast. Lower SGD (37.24 – 79.16 cm/day) were observed during fresh groundwater discharge.

Abstract

A study on colloids in groundwater and its relationship with the geochemical parameters is reasonably essential because of its facilitating nature to transport radionuclides in groundwater. Colloid sampling has been carried out in the coastal aquifers of southeast coast of India. Two different bore wells were selected based on the distance from the coast to collect groundwater samples. On the basis of the result achieved from this study, a reliable representation is emerging. The values of pH and EC are governed by the different size fraction of colloids. In this study, the relation between different size fractions of groundwater colloids and its pH, TDS and EC were carried out. These parameters were analyzed in the lab and its influence with four fractions of colloid like 1.2, 0.8, 0.45 and 0.22 µm have been discovered by smooth scatter plot. The accumulation of particles weighting by normal weighing instrument. There is an higher accumulation of particles found in Kalpakkam than Anupuram in all the size fractions. For separation of particles high frequency pressure was used by ultrasonic cleaner had been carried out. This method is very simple and more reasonable than any other methods.

Abstract

In Gadilam river basin, groundwater is found in both hard rock and sedimentary terrain and is the most important source of rural/urban drinking water supply. Gadilam river basin has gained its importance due to the presence of Neyveli Lignite open cast mine (NLC), group of industrial estate (SIPCOT), extensive depressurization of Cuddalore aquifer and boreholes of New Veeranam Scheme (NVS) in the downstream of the basin. A total of 178 water samples were collected in four different seasons at various lithologies. The collected samples were analyzed for various physico-chemical parameters using standard procedures. Geochemical indicators of groundwater were used to identify the chemical processes that control hydrogeochemsitry. Interpretation of hydrogeochemical data suggests that leaching of ions followed by weathering and anthropogenic impact controls the chemistry of the groundwater. Isotopic study reveals that recharge from meteoric source in sedimentary terrain and rock water interaction with significant evaporation prevails in hard rock region. This thorough understanding helps us to make judicial usage and to maintain the quality of this commodity.

Abstract

The development and management of fresh groundwater resources in coastal aquifers are seriously constrained by the impact of seawater intrusion. The coastal aquifers are fragile and this situation becomes more intense like that of the coastal Cuddalore region. The geochemical signature of groundwater of Cuddalore coast was studied for Pre Monsoon, Southwest, North east and Post Monsoon seasons by collecting total of 64 groundwater samples in each season. The collected samples from were analysed for physical parameters, such as electrical conductivity (EC), pH and major ion concentrations, such as Ca, Mg, Na, K, Cl, HCO₃, PO₄ and SO₄. Interpretation of analytical data shows the predominance of  Na–Cl type   in PRM and Ca- Mg-Cl type  is the dominant facies during POM. The Chaddas evaluation diagram shows that the hydrogeochemical evaluation plot for PRM samples fall in  Na-Cl type. The ratios of Na/Cl and Cl/HCO₃ is also enumerated the fact that the most of the samples from PRM and few samples from other seasons also indicates dominance of salt water intrusion.

Abstract

Aquifers are usually composed of permeable layers that can ways a considerable amount of groundwater. Usually, aquifer units are correlated through the concept of lithostratigraphy. For low-permeable aquifers, it is difficult to define the spatial distribution of hydrogeological units, and this study attempts to use geochemical methods to identify the groundwater flow paths in an area of Southeast coast of Tamil Nadu, India. Multiple geochemical analyses, including groundwater chemistry; stable isotopic compositions of d¹⁸O and 8D contents were performed.  Spatial distribution of d¹⁸O, dD, Cl-/HCO-₃ show that northeastern part of the study area seriously affected by seawater intrusion. The highly permeable aquifers at the east coastal region are characterized by high hydraulic conductivity as compared with other regions of the study area. Hydrogeochemical characteristics based on bivariate diagrams of major and minor ions show that changes in the chemical composition of groundwater are mainly controlled by the salinization process followed by cation-exchange reactions.

Abstract

Dissolved Organic Carbon (DOC) consisting of water soluble organic molecules and by products of organic decomposition and chemical degradation processes, constitutes a critical link in carbon and nutrient cycles. The quality, or chemical and physical character, of DOC affects the degree to which it is transformed by biological and chemical processes. The significance of DOC was studied in layered coastal aquifers of the Pondicherry region during four different seasons. Pondicherry region has varied geological set up ranging from Cretaceous to Recent formations. A total of 52 groundwater samples were collected from various aquifers like Alluvium, Tertiary(Upper Cuddalore, Lower Cuddalore) and Cretaceous for two different seasons of pre- monsoon(PRM), and post-monsoon (POM). The samples were analyzed for major ions and DOC. The range of DOC in the study area is 0-14 mg/l. Very high DOC concentrations were measured during PRM in the samples from Alluvium and Lower Cuddalore Formation. The samples of these formations were compared with pH, Ionic strength, log pCO₂ and carbonate minerals concentration. The alluvial aquifer shows that pH governed dissolution along the coastal tracts and in Upper Cuddalore formation it’s based on interaction between aquifer matrix and groundwater.

Abstract

Groundwater is most favored as a source of drinking water in all over world. It is often thought to be cleaner and easier to treat when compared with surface water and as a result, many wells have been sunk. Uranium and other radionuclides in water can lead to health problems if present in higher concentrations. In order to study the behavior and to understand the influence of lithology in groundwater of Madurai district, a study was conducted by collecting a total of 216 samples of different seasons (Premonsoon, South west monsoon, Northeast monsoon and Post monsoon) with respect to lithology and the number of samples was depending upon their spatial coverage in the study area. The groundwater samples were analysed for U, Ca²⁺, Mg²⁺, Na⁺, K⁺, HCO₃^-, Cl^-, SO₄^2-, PO₄^3-, NO₃^-, F^-, H₄SiO₄, pH, EC, TDS. It was identified that the higher concentration of Uranium (156 ppb) were noted in the northern part of the study area. They are chiefly restricted to the Granitic terrain and nearby Charnockitic regions. The weathering process induces the release of higher U ions from the granitic terrain and the evaporated recharge water from the tank /reservoir  also induces the release of U ions from the rock matrix, it may also be due to fertilizer enriched agricultural return flows. The key source for all these processes and hydrogeochemical processes is identified to be lithology which inturn controls all the other processes in the study area.

Abstract

Amongst all types of major land-use change, extending irrigated agriculture using a surface-water source has the greatest influence on groundwater – both significantly increasing recharge and changing water quality as excess irrigation water infiltrates into shallow aquifers. Hence, in order to understand the impact of the landuse on the groundwater system the study has been aimed to understand the process by adopting geophysical, geochemical and microbial analysis of groundwater samples. The study has been conducted in Chidambaram taluk, with a total area of 92.51Sq.km. A total of 39 groundwater samples were collected for the analysis of major cation and anion along with the microbial analysis, like Total Coliform, Total Viable Counts, Fecal coliforms, Vibrio cholera and Total Streptococci. The geochemical studies reveal that there is no correlation between these parameters and the microbial population. The migration of the water from the elevated regions (urban region) is witnessed and the concentration of the microbial population is higher in these regions except in the southern region which has impermeable clay and this arrest the movement of water.

Abstract

Geochemical processes occurring within the groundwater and reactions with aquifer minerals have a profound effect on water quality. Hydrogeochemical composition of groundwater can also be indicative of its origin and history of passage through underground materials which water has been in contact. Assessing groundwater quality and developing strategies to protect aquifers from contamination are necessary aspects for proper planning and designing water resources. Anthropogenic activities like explosion of population, industrial growth, inputs of fertilizer, pesticides, and irrigation has been a crucial factor for determining the quality of groundwater. In this scenario, 43 groundwater samples were collected from the Dindigul district of Tamilnadu, a Hard rock terrain. The samples wereanalyzed for major cations and anions along with heavy metals to derive the different quality parameters and to obtain the pollution indices of different samples. This study focuses to find out the spatial relationship between the analyzed fluoride concentration in groundwater and pollution indices derived from the heavy metal concentration in the groundwater of the study area and their variation with respect to season.

Abstract

The Indian western Himalayas have wide variation in altitude, climate, soils, flora and fauna and socio-economic features. Livelihood options are limited due to small and fragmented holdings and inherent hill and mountain specificities. However, the physiographic and agro-climatic variability also offer opportunities of cultivating wide variety of profitable traditional and market oriented crops for exploiting niche advantage. Non-timber forest products play a vital role for livelihood security and demand that initiatives at local and governmental level are taken to develop and popularize technologies for collecting, processing and value adding to these products for commercial exploitation. Research and self help institutions are important in this context but strong regulatory policy framework is equally important. Further, need based and location specific trainings and demonstrations need to be organized to fill the knowledge void especially in traditional activities and emerging vocational enterprises. The national and international business concerns, engaged in exploiting natural resources such as hydro power and calcareous and limestone deposits should also engage more meaningfully in this task, under their corporate social responsibility (CSR) Livelihood generating scheme such as MNREGS should be extended to the non-conventional activities like weed eradication, management of wild (monkeys) and stray (cattle) animals that threaten livelihood security.

Abstract
The western Himalayan region is rich in a variety of natural resources owing to the existence of a range of biophysical and climatic interactions. Mountain inhabitants have been living in harmony with these natural resources for generations to meet their subsistence needs out of these resources.  However, recent decades have witnessed a substantial imbalance between man and nature that has adversely affected the livelihood of native people. Several anthropogenic and natural factors are responsible for this change. Furthermore, the exposure of mountain societies to outside world has opened up a number of new livelihood options based on both natural resources and other forms of human capital. The local people have adopted some livelihood practices suiting to the changed conditions at the expense of the age-old agri-silvi-pastoral mode of livelihood. There is an emerging challenge for policy makers and planners to make developmental interventions and tailor made livelihood options suiting to the changed scenario. Several government and non-government organizations and other agencies initiated a number of programmes that focus on natural resource management vis-à-vis livelihood improvement in the region. However, for want of cause and effect analysis many of these programmes are not yielding the desired results. This chapter provides an overview of the traditionally important livelihood practices of the western Himalayan region and some of the emerging livelihood supporting activities based on natural resources of the region. A case study of Bhimtal lake catchment where transformation of traditional livelihood has taken place at a rapid pace due to the influence of tourism and urbanization has also been included to highlight the emerging scenario. The paper suggests some useful policy options for planning livelihoods in the western Himalayan region of the country.

Abstract

The livelihood security of hill people is closely associated with hydrology of the region. The Himalayas possesses one of the largest reserve resources of freshwater in the form of snow and ice, thereby supporting livelihoods of millions of people. The physiographic constraints of the region restrict irrigation development with the result that, majority of cultivated area remains rainfed. Climate change is also a serious issue concerning hill economy. Its impact on livelihood security is dictated, among other things, through change in hydrology. In addition to highlighting hydrological issues, suggestions are offered on how to deal with water related issues to livelihood enlargement and protection.

Abstract

The paper presents findings of a field study to determine the agricultural and socio-economic impact of climate change on the mountain farmers’ apple economy. The study investigates the positive and negative effects of climate change on mountain farmers’ economy. It revealed how mountain farmers in a valley were forced to abandon apple farming which destroyed their farm economy and at the same time how same climate change brought new economic opportunities. The study findings also indicate that opportunities brought by climate change seem to have a time scale. This research attempts to piece together evidence and aims to enhance our understanding of climate change impacts as observed by farming communities at very local levels. The growing threat of global warming and its effects and prevailing obscurities about the future of agriculture are all addressed in this investigation.

Abstract

Hills and mountains are an important agro-ecosystem, which have lagged  behind the plains in respect of agricultural development. The plains of India witnessed green revolution followed by white, yellow and blue revolutions, which not only increased production and productivity of food crops but helped in bringing about overall development that led to livelihood security in the rural India. The hills, however, remained technologically backward resulting in low agricultural productivity, which brought about livelihood insecurity in these areas. And this has happened despite the fact that a large number of top class institutions of the CSIR, ICAR, ICFRE, Atomic Energy 
Commission, GSI and BSI along with State Agricultural Universities have been present (in the region) and were engaged in developing technology relevant to agriculture and allied areas. However, these technologies did not reach to the end user i.e. the hill farmer for a variety of reasons. Therefore, technology development and dissemination have been accorded high priority by the state governments.

Abstract

Livelihood of ~80% of rural inhabitants depends upon agriculture that relies upon the prevailing environmental conditions such as water availability and temperature. If unfavorable to the crops, these conditions would impact production and productivity leading to food-insecurity. Various abiotic stresses are generated due to the physiography that includes altitude, topography, edaphic factors, water availability and ecosystem degradation. In spite of the environmental limitations, crops have survived suggesting operation of relevant adaptive mechanisms in the native species. Indeed, novel genetic mechanisms were present and these could be utilized to improve the plant productivity under stress conditions. Also there are issues on the management of abiotic stresses, which need to be addressed. The chapter presents framework and policies on sustaining agriculture production under the situations of abiotic stress to ensure production sustainability by protecting livelihood of the inhabitants. Western Himalaya was deliberately chosen as the focus for discussion.

Abstract

Over the years, global climate change has negatively impacted the resources of western Himalayan region and the diversity of floral wealth has been endangered. The endangered livelihoods of agriculture based sector call for incorporating stress resistance by sustained effort that includes resort to infusion of new technologies. Biotechnology offers possible solutions to many of the intractable problems. Development and commercialization of transgenic crops have witnessed phenomenal growth in recent years. An array of traits viz. insect pest resistance, herbicide tolerance, abiotic stress tolerance, augmentation of nutritional qualities etc. have been targeted and successfully modified through plant genetic engineering. The global area of transgenic crops has seen a tremendous increase to attain 148 million hectares in 2010. Progress in understanding plant genome structure and function by high throughput characterization of genome, transcriptome, proteome and metabolome is providing new opportunities to deal with complex traits that result from interactions of a large number of genes. The other significant application of biotechnology in crop improvement has been “Marker Assisted Selection” (MAS). Development and integration of DNA based markers in the selection process has empowered the breeder to identify the desired genotypes without any interference of environmental effect or tissue specificity of expression. Cultivation of MAS derived crop varieties in the country bears testimony to the success of this technology.

Abstract

Invasion of field crops, orchards and waste-lands by weeds is a matter of concern for farmers and foresters because of the drag they inflict on productivity and the increase in cost of production involved in weed control. Science-based technologies offer workable and reliable recourse to minimizing and/or eliminating these losses to promote healthier and rewarding livelihoods. While studies have been conducted to combat brush-weed in waste-land and plantations, little work has been done on such aspects as biological control of weeds, development of herbicide resistance in weeds, and allelopathic interface of crops and weeds. In this chapter, attempt is made to assess the economics of weed management in major crops. Aspects of R&D on weed management that should be addressed for safeguarding yield in the future are highlighted with particular reference to situation in western Himalaya.

Abstract

Extreme weather conditions often cause considerable damage. Much of this damage can be mitigated if people are better prepared for impending disasters. Therefore, public authorities and private enterprises have been investing in Early Warning Systems (EWS). Environmental degradation and destruction of natural resources has been faced by humans and other organisms for hundreds of years. Some of these incidences have been caused by natural climatic and geologic processes and others by human activities. These natural disasters have been increasing over time due to factors such as urbanization, population growth, destruction of natural environment and climatic change. Biogenic and anthropogenic related environmental and natural resources degradation has direct economic and health impacts on affected regions. Land and water degradation as well as disasters such as floods and droughts have led to famine, hunger, disease, death and created many other problems. It is necessary, therefore, to keep focused on the ultimate goal of reducing disasters by all possible means. India must invest generously on infrastructure and resources for preparation of early warning systems and disaster preparedness.

Abstract

Vegetable crops are inherently rich sources of various health-promoting nutrients and thus they play an important role in balancing our daily diet. Being excellent source of vitamins and minerals, vegetables have a relatively variable nutrient content per unit of energy. These nutrients can be increased by proper selection of vegetables in our diet. Whereas their intrinsic quality maintains human health, the extrinsic quality has significance in determining acceptability by the consumer. Vegetables also have medicinal properties. These diversified and highly nutritive crops are of great importance in alleviating hunger and malnutrition. The present production of vegetable crops is, however, not enough to meet per capita daily dietary requirement as per dietitians’ recommendations. The vegetable production, therefore, need to be almost doubled by 2025 to meet requirement of ever increasing population from diminishing land, water and other natural resources. Although, there has been a trend of increase in production and productivity of vegetable crops since liberalization of seed trade in 1988 by Government of India, yet it has not been commensurate with the requirements. Compared globally, we are far behind in productivity of vegetable crops in spite of being second largest producer after China.

Abstract

Agricultural produce, such as vegetables, flowers and some fruits capture higher market price if they can be produced ahead or later than the main crop season. The demand of such unseasonal products is particularly high in the fashionable markets of big cities. Good quality of the product is, however, an essential requirement to realise this price advantage. Modern technologies can pave the way to take the full advantage of high price realisation. Growing crops under protected covers is being popularised and the application of various approaches of greenhouse technology can further extend this advantage because it offers greater control over the production environment and timing of crops. There has been a consistent increase in area under greenhouse cultivation nationally and is turning out to be a useful technology for resource efficient agriculture. The types of greenhouse structures range from hi-tech climate controlled systems to very elementary trenches or solar greenhouses used in high altitude cold desert regions of the Himalayas. Greenhouse vegetable production on a commercial scale is a capital and labour intensive production system and requires proper planning for sustainable production. Higher yield, efficient resource use, earliness, off-season availability and superior quality is the hallmark of greenhouse grown vegetables. Greenhouse vegetable production can be done from very basic soil based planting to fully automated hydroponic or soilless systems. This production system requires specialised crops and cultivars which should meet the demand of high value markets.

Temperate horticulture in Himalayan States forms the backbone of states economy by providing livelihood to more than 10 million people and draws about 60% of its Gross Domestic product (GDP) from the surrounding ecological resources. Being an important sector it has been given priority in recent years through various developmental programmes to harness the vast potential of natural resources, the topography, soil, climate and horticulture crop diversity. The outburst in climate and over population have become a major concern challenging natural resources of the Himalayan region for sustainable development of agriculture and improving livelihood of the local inhabitants. Depleting natural resources and vagaries of weather are negatively affecting long-term sustainability of Himalayan agri-horti production system. In spite of several chal-lenges the horticulture in temperate region has made some progress. The area, production productivity, availability and export of horticulture products have increased manifolds leading to improvement in employment and farm income. But still the temperate fruit industry is far behind and is facing the problem of low productivity and high cost production due to lack of elite planting material, old and senile orchards, rainfed farming, lack of efficient water, nutrient and canopy management, high infestation of insect and pests, poor transport and communication coupled with weak post harvest infrastructure. The modern new high yielding varieties and technological interventions developed especially the high density plantations; canopy & pollination management; fertigation, INM and water harvesting; cost effective and eco-friendly protection technologies and post harvest management and value addition have shown great potential to revolutionize the horticulture sector to bring paradigm shift from existing low quality lower productivity sector to high quality-higher productivity sector. The farmers have an opportunity and can take the advantage of emerging technologies in temperate horticulture to improve their nutritional and livelihood security.

Resistance of some plants against a pathogen is due to their belonging to taxonomic groups which are outside the host range of the pathogen. Such resistance is called non host resistance. It is attributed either to genes for resistance (R genes) against the avirulence genes of the pathogen (true, race specific, cultivar-specific, or gene-for-gene type resistance), or to the plants escaping or tolerating pathogen infection due to various reasons (apparent resistance). There are two kinds of true resistance: partial (also called quantitative, polygenic, or horizontal resistance) and R gene resistance (also called race specific, monogenic, or vertical resistance). Several examples of true resistance attributable to, biochemical underpinning or genetic transformation of host plants of major fruit crops viz., apple, pear, apricot, plum, cherry, almond, mango, grapes, banana, citrus, papaya, guava and pomegranate against important plant pathogens are known. Much greater efforts need to be invested, however, for incorporating resistance to diseases in horticultural species because of their huge relevance to socio-economic well being of farming community of the hill regions. The effort in this chapter will be towards synthesizing information which officials of the administrative and development departments can use for drafting plans and policies for promoting protection and up gradation of livelihoods of hill farmers.

Use of insect-resistant varieties in integrated pest management is an economically and ecologically sound alternative to synthetic pesticides. A large number of germplasm lines of different fruit crops have been evaluated for resistance to pests, and a few genotypes with resistance to insects, mites and nematodes have been identified. The resistance of “Winter Majetin” apple variety against woolly apple aphid, Eriosoma lanigerum (Hausmann) was the first report of innate resistance to insect pests in fruit crops. Another successful example was the resistance to grape phylloxera, Daktulosphaira vitifoliae (Fitch), in which the susceptible European scions (Vitis vinifera) were grafted onto the resistant American rootstocks (Vitis labrusca) in late 1800s. Various leaf characteristics, such as hairiness, pubescence, thickness of veins, sponginess, stomatal density and fruit characteristics such as rough skin, have been reported to confer resistance to insect pests. High content of phenols, flavonols, potassium, calcium, and low carbohydrate and nitrogen contents have also been reported to confer insect resistance in various fruit plants. The germplasm has been screened against various pests under natural as well as artificial infestations. In apple, rootstocks (MM-series) resistant to woolly apple aphid have been developed. Molecular markers for three genes that confer woolly apple aphid resistance are located on two linkage groups (LG). Low infestation of the woolly apple aphid has also been recorded in Golden Delicious variety which incidentally is the most preferred host of apple fruit moth. The scab resistant apple selections, HCR21T200, HCR23T125, S80ER21T72 and TSR16T223 have also been found to be resistant to the European red mite, Panonychus ulmi (Koch). Peach varieties such as Flaming Gold, Stark Early Giant, Early White Giant and Flavour Crest are moderately susceptible to the peach leaf curl aphid, Brachycaudus helichrysi (Kalt.). Peach cultivar, Matchless has been reported tolerant to flat headed stem borer, Sphenoptera lafertei Thomson. Early maturing varieties of peach are reported to escape the fruit fly, Bactrocera dorsalis (Hendel) damage while Nemaguard, and Nemared rootstocks are resistant to important nematode pests. Almond varieties, Briggs Hard Shell, Katha 85, Ribba Selection and Tree No. 55 have been reported free from peach curl aphid infestation.

Current and emerging animal nutrition, reproduction and health management technologies have the potential to improve efficiency of livestock production. However, the thermal stress or hyperthermia caused by elevated ambient temperature reduces feed intake, milk yield, growth rate and reproductive performance of livestock species. Livestock in tropical countries will be affected severely by the abrupt and fast-paced climate changes. The impact is not only on production traits, a number of animal species may become endangered. Many of the native livestock species still perform better under climatic stress and low-input conditions. It is necessary to catalogue the indigenous livestock genetic resources, elucidate their genetic make-up and regulation of key metabolic pathways of adaptation and productive attributes and using the inferences to develop strategies for utilizing livestock resources under climatic stress.

In spite of its importance, little has been done to assess interactions of climatic variability with productivity performance of different livestock species, sustainability of livestock production systems, livestock based livelihoods and application of science of climate change on small holder and subsistence livelihoods. The climate and its change affect all productive traits and physiological functions of farm livestock and related livelihoods. Heat stress is the most detrimental constraint to livestock production, particularly in mountainous regions. Introduction and selection for highly productive animals and breeds has increased their susceptibility to adverse impacts of climate change. It is necessary to incorporate resilience through selection and breeding for thermo-tolerance and development of adaptable breeds. Modifications in shelter designs and management of production facilities will also be helpful in mitigating adverse climate impacts on animal production and health. Modern animal husbandry practices that target increased per animal productivity allow efficient utilization of feed nutrients and increase returns from fewer animals. Livestock need to be looked for their immense contribution to nutritional security and livelihoods. A well designed livestock production system is among the best ways for sustaining and improving livelihoods and this chapter details the possible options.

Yak is among the most remarkable domestic animals. It is adapted to thrive in the harsh environment of high altitude and sustains livelihood of highlanders. Yak is handicapped because of lack of veterinary assistance and declining pastoral biomass. Marketing facilities for yak-based products are limited and the production potential of yak husbandry is on decline. Dearth of locally available trained manpower and prevailing illiteracy are other hindering factors for development of yak husbandry. Research and development with focus on upliftment of yak husbandry and yak products are therefore important.

Animal husbandry plays a vital role in the development of agriculture and is an integral component of rural economy especially in the hilly mountainous terrains of the country. Disasters, whether caused by unavoidable natural events or by avoidable, man-made events, always have been a part of human life. Hilly areas because of their geo-physical and climatic conditions are always prone to natural disasters like earthquakes, volcanic eruptions, cloud bursts and landslides etc. During the past few decades, disasters have killed millions of people and animals, adversely affecting the human and animal lives, resulting in substantial tangible and intangible losses in an unanticipated manner. Veterinary professionals by virtue of their strong scientific and technical competence play a pivotal role in human health by providing safe, wholesome and sound animal proteins which are valuable component in the prevention of malnutrition. Moreover, public health veterinarians are also actively concerned in protecting the environment by safe disposal of human and animal waste without adverse consequences. Thus, veterinarians always have a role to play in all stages of disaster mitigation and management; however the contribution of veterinarians will be most effective by integrating their expertise with other local, national and international groups and agencies involved in disaster management. In any country, funding for disaster relief should include veterinary management of disasters being recognized as a form of humanitarian assistance and a contribution to public health.

Coldwater fishes exhibit enormous diversity and have great potential for generating livelihoods, mitigating poverty and unemployment. Coldwater fishery deserves attention for improving production by ensuring seed and feed supply. Other important issues in fisheries sector relate to marketing, value addition and farming. There is need to have separate action plan for low volume high values, and high volume low values fishes. Coldwater fishery sector can be strengthened using the available technologies such as hatchery and seed rearing, management protocol breeding and grow out protocols, fish specific feed formulations, exotic carp farming, and fish farming in polythene lined irrigation/ watershed tanks. The sustainable fishery development in hills requires attention on defining and granting appropriate ownership of resources, developing state of art infrastructure, initiation and implementation of fisheries conservation including focus on native and exotic species through enforcement of protective legislation. Strengthening of hill fishery education will play a central role. A “strength, weakness, opportunity and threat analysis” suggests an integrated approach by addressing the issues on genetic characterization and conservation, environmental impact analysis, development of niche specific aquaculture system, focus on post production and health management issues, implementation of demonstration programmes, enhancement of institutional capabilities, and development of human resources. Research areas relating to capture fisheries, culture fisheries, extension and transfer of technologies are also important.

Northwestern Himalayan region is spread between 28°43^'-37°05^'N latitude and 72° 40^'-81°02^' E longitude covering an approximate area of 33 million ha. The major natural resources of western Himalayas are water, forests, floral, and faunal biodiversity. Although there is wide spectrum of farming systems diversity in the region, yet there are quite a few commonalities viz. crop diversity, including mixed cropping as well as crop rotation of subsistence nature rather than commercial nature of agriculture, maintenance of soil fertility through natural processes. The variability in agroclimatic conditions in the hilly regions of India due to geographical location and climatic conditions require micro planning for assuring sustainable agricultural production. Introduction of horticultural crops is more recent phenomenon and it has penetrated the traditional farming systems of Himachal Pradesh, Jammu and Kashmir and central Himalayan region for commercial benefits than the local consumption. Climatic conditions are optimal for growth of many food, medicinal and other commercial crops and live stock occur in these hills and the need is to exploit these opportunities for economic upliftment of the region, without degradation of natural resource base, therefore a long term development approach for sustainable farming system in these hills must have an eye on conservation farming for developing various production systems since this is a highly fragile system. The agriculture including livestock continues to be the dominant sector despite the fact that the area is exposed to adverse and harsh geophysical and agri-silviculture conditions. Strategies by planting fodder trees or grasses in the waste/ degraded lands (representing 7.9, 9.8 and 11.5% of the geographical area in Himachal Pradesh, Jammu and Kashmir and Uttarakhand, respectively), is needed for enhancing the fodder production. In addition, farm spaces on terrace risers and improved crop production technology coupled with integration of agroforestry will help in bridging the gap between demand and supply of the fodder. The indigenous agroforestry systems such as homestead (kyaroo), plantation crop combinations, scattered trees on farm lands/field bunds and bamboo grove are practiced by the farming community. The land management operations are predominated by different indigenous agroforestry practices which have proven potential and hold promise in alleviating the poverty among rural masses of this hilly region. The agroforestry systems provide unique opportunity for integration of different components in the farming systems, which help to optimize the ecosystem functioning and better management of land, water, and biological resources. These systems need to be further improved with suitable technological interventions considering the local population need, so that the socioeconomic status of the farming communities uplifted. Experiences gained in managing natural resources through well-tested agroforestry systems have been shared in this chapter.

The Himalayan region is recognized amongst the 34 global biodiversity hotspots. The Indian Himalayan Region (IHR) comprises of five biogeographic provinces, covers approximately an area of 591 thousand km² and extends from Jammu and Kashmir in the north-west to the Arunachal Pradesh in the east. The IHR is a source of great diversity of food, fuel, fodder, timber, dye and medicinal plants. It comprises about 18% of India and is more than 2,800 km long and 220 to 300 km wide, with altitudinal range of 200–8,000 m. The IHR alone supports about 8,000 species of angiosperms, 44 species of gymnosperms, 600 species of pteridophytes, 1,737 species of bryophytes, 1,159 species of lichens and 6,900 species of fungi. The state Himachal Pradesh is divided into four conspicuous zones, namely Shivalik/lower montain zone, mid-hills/middle mountain zone, high hills/temperate zone and cold dry zone. Five rivers namely Satluj, Beas, Ravi, Yamuna and Chenab with a large number of their tributaries flow through the state. The flora of the state consists of about 180 families comprising about 1,038 genera and about 3,400 species. The region is facing greater and more difficult challenges than ever before in achieving balanced economic growth, alleviating poverty, and sustainably managing the renewable natural resources. People’s dependence on forest and related natural resources is historic, cultural, and inevitable as other viable alternatives for earning a living have been few. The consequence of this trend has been the commercialization of forest products, mainly non-timber forest products (NTFPs). The NTFPs are the major bioresources among various natural resources available and provide various ecosystems services to the mankind. Like other parts of the IHR, in Himachal Pradesh people earn their livelihood from the forests in many ways i.e., earning cash income; satisfying their needs for fuel, medicine, shelter, and supplementary food; using traditional agricultural inputs such as leaf litter, fodder, small tools, and water; and cultivating land inside the forest boundaries as forest encroachers. Their dependence on forest resources is both historic and cultural to the extant that it is an integral component of the forest ecosystem of the region. Although, large amounts of NTFPs are collected by different communities in the state, no comprehensive study on the amount collected, number of people engaged in collection and trading, and the marketing chain involved has been carried out to date. Therefore, the present study focuses on conservation and sustainable utilization and market potential of different tradable medicinal plants/(NTFPs) in Himachal Pradesh, north western Himalaya.

The relationship between man and plant resources of his surroundings is intimate. Of the 350 tribes inhabiting different parts of India, about 171 dwell in Himalayan region. The inhabitants of the mountain areas use native flora for food, fodder, fiber, fuel, timber and for health care of both human beings and their livestock. These plant resources, particularly medicinal and aromatic plants (MAPs), not only meet their health care needs but also support their livelihood. Recently the demand of MAPs has transformed from local and traditional needs to global needs. This has adversely affected availability and quality of raw material as also livelihood and health options of the local people. Most of the raw materials are gathered from the forests, and only a few plants are under cultivation. To avoid rampant exploitation of MAPs from nature, there is an urgent need to establish procedures for their cultivation and organized marketing. The present article deals with strategies and actions to protect livelihood options of the indigenous communities inhabiting mountain areas in western Himalaya as well as promote sustainable utilization of MAPs through scientific and technological interventions.

Introduction

India and China are two major Medicinal and Aromatic Plants (MAPs) producing countries, providing 40% of the global diversity and availability of rare species. The Ministry of Environment and Forests, Government of India has identified and documented over 9,000 species of medicinal plants that are significant for the pharmaceutical industry (AICRPE 1996). Of these, 2,000 to 2,300 species are used in traditional medicines while at least 150 species are used commercially on a large scale (EXIM Bank 1997).

Abstract

The hilly regions of western Himalayas comprise of three states namely Jammu and Kashmir, Himachal Pradesh and Uttaranchal which are divided into High Altitude Temperate, High Hill Temperate and Valley Temperate zones. Through observations, trial and error, man has developed skills related to cultivation, utilization and livelihood. These were transmitted through generations and in this way, a system of traditional knowledge developed and moved forward for the benefit of the society. Food is the basic necessity for the survival of human beings. Since ancient times, various methods have been used to process and preserve foods especially in the Himalayan regions. The food habits and preparation of various dishes depend upon the availability of crops and surrounding vegetation. On the basis of the substrate used, traditional foods and beverages of Himalayan region are broadly classified as Cereal and Legume based, Milk based, Fruits and Vegetables, and others. Some of the popular traditional foods of Himalayan region are Aenkadu/Askalu, Bagpinni/ pinni, Chhangpa, Chaulai ka bhat, Kutu ki roti, Lesuwa roti, Tilkuta, Kaddu ke khwaire, Mooli ke khwaire, Sarson ki dhusi, Arbi ke sukhe danthal, Chaulai ki kheer, Ogal ka halwa. Traditional fermented foods and beverages are very popular in the tribal and rural areas of western Himalayas. Besides being source of nutrition, these fermented foods constitute staple food (Bhaturu) in larger part of western Himalayas while others are consumed during local festivals, marriages and special occasions. A variety of indigenous fermented foods and beverages available are; Kinema, Marcha, Phab, Bekanthu, Gundruk, Sinki, Soibun, Sura, Chhang, Daru, Angoori/ Kinnauri etc.Due to lack of proper scientific technology the quality of such foods especially beverages (many- a- times) is uncertain and their consumption leads to a higher incidence of fatal diseases among the consumers. This chapter briefly reviews the preparation, significance and quality of indigenous foods of Western Himalayas which offer tremendous opportunity for sustaining livelihood of the people of Himalayan region and stimulating agro-industrial development even in the developing countries, after upgrading and sustaining their quality.

Beekeeping symbolizes the biological interdependence between insects, pollination and production of seed. Honey bees have been tirelessly rendering this yeoman service to benefit human-kind since time immemorial. Beekeeping is defined as “the science and art of rearing honey bees for man’s economic benefits”. Since, honey producing bees are restricted to the genus Apis beekeeping is also called ‘Apiculture’. A suitable place selected for housing honey bee hives, equipments and related accessories is referred to as an “apiary”. The invention of movable hive with separable frames in 1851 by L.L. Langstroth gave beekeeping the impetus to flourish. Further fine-tuning of scientific rearing techniques in these movable hives helped in spreading beekeeping to the newer areas.

Honey Producing Species of Bee

About 20,000 bee species are found worldwide. However, only four species viz. the European honey bee (Apis mellifera Linnaeus), the oriental bee (A. cerana Fabricius), the dwarf bee (A. florae Fabricius), and the giant or rock bee (A. dorsata Fabricius) are commonly recognized as honey producing. Amongst these two, only A. cerana and A. mellifera are hived because these build multiple-combs in dark cavities. The other two build single comb nests in the open (Akratnakul 1987a, Ruttner 1987).

India occupies second position among the silk producing countries of the world, next only to China. Sericulture as a farm enterprise is highly suited to rural poor, especially small and marginal farmers and other weaker sections of the society, since it requires low investments but provides good and quick returns at individual family level. Several socio-economic studies have established that cost-benefit ratio in sericulture is highest compared to agricultural crops. Though there are limitations to the number of broods that can be raised per year in Himalayan region due to ecological conditions, net returns from sericulture activities are quite remunerative and effectively supplement the rural economy through part-time employment opportunities and utilization of local resources.

Introduction

Ever since its discovery, silk as a unique product of a plant-animal interface, continues to reign supreme despite the onslaught of natural and man-made textile fibres, because it is exclusive and the most beautiful of all textile fibres. It is associated with comfort, festivity and fashion.

Sericulture has established itself as an economic activity with a rural-base. It presents an intriguing example of an agro-industry whose potential to act as a safety-net for the poor in rural areas is unquestionable. From “Soil to Silk” activities, sericulture creates around 6 million person-years of incomegenerating opportunities. It generates employment @ 11 man-days per kg of raw silk production in a year in associated upstream and downstream activities. Sericulture is thus a labour-intensive cottage industry in all its phases, namely, host plant cultivation, silkworm rearing, silk reeling, and other post-cocoon processes such as twisting, dyeing, weaving, printing and finishing.

In his classic book ‘The Ascent of Man’, Bronowski has written, “When I was a young man, we all thought that mastery came from man’s domination of his physical environment. Now we have learned that real mastery comes from understanding and moulding the living environment.” Our Biosphere, the living environment that supports us all, has problems and we humans are mainly responsible. We do not live ‘gently’ on the earth. The seven billion of us require air, water, food, energy, housing and amenities and we have developed the earth to provide them and have also created problems. That the problems exist are serious is the bad news. That we are recognizing them and that man has shown ability to organize and grow in ascending order from time to time is the good news.

It has been repeatedly proving that Science& Technology that is close and in harmony with nature is proving winner in the long run. If the past 60 years led to the Green Revolution in agriculture which often became Greed Revolution, the next 60 year should be the emergence of love for nature, diversity and Sustainable Green Revolution. The two goals – Sustainability and Productivity are inter-related.

It is also said that the main difference between the past and today is that our problems are truly global. We are also aware that globally and nationally the rich-poor divide is growing and though world produces enough food, nearly 800 million people remain food insecure. Among 8 millennium goals, eradication of poverty and hunger and environmental sustainability are perhaps the most prominent and complimentary.

The words “Economy” and “Ecology” have the same root. Both these words are derived from Greek ‘Oikos’ means house or house holds and both imply thrifty economical way of dealing with valuable resources. However, for some reason we seem to find these two words coming opposite each-other in many situations.

The destruction and degradation of the environment has become the greatest problem of our century. Our survival will depend on how well we are able to redefine our technologies and our relationship with nature. We therefore need a new sustainable eco-agri revolution and a country like India is in an ideal situation to give a model for that. In the new economy, good ecology will be fundamental to good business.

African agriculture is in crisis, and Africa’s farmland is losing its fertility at an alarming rate. Farmers grow the same crops in the same fields year. They don’t fertilize, and they don’t terrace their fields. When the soil wears out, the clear a new piece of land (wwww.npr.org). N. Kozana Diamini Luma, the Chairperson of the African Union Commission has emphasized that ‘the year 2014 – the year of Agriculture in Africa’ will be used as an opportunity to accelerate the drive for food security. The major thrust for that has to be on ensuring that the farmers make their profession on economic activity that generate wellbeing for all in a sustainable manner (1, 2).

Higher Farm Production with Lower Input Cost

There is a great need to reduce the input costs and at the same time improve the farm productivity in a sustainable manner. A model has been worked out based on a number of field demonstration studies in different parts of India, Africa and Far Eastern countries. A model in which input cost can be reduced by nearly 20 percent and at the same time the crop production can be enhanced upto 20 percent is possible and can be a boon to farmers in most parts of the world. This is the model, which can be easily adopted in an evolutionary way. As suggested by Jonathan Foley (BOX – 1), use of high-tech, precision farming systems, as well as approaches borrows from organic farming, we can boost farm productivity substantially.

To many Bio Fertilizer is still an unclear term. Often they are identified as urban and rural organic wastes, plant extracts, organic components etc. However, Bio Fertilizer is mostly commonly referred to the use of soil micro organisms to increase the uptake and availability of plant nutrients.

Bio Fertilizer have gained a good deal of momentum and the industry after a slow start is now gaining more and more importance globally. The major reasons for this are that they:

At an Agri Summit, I had a very difficult task to chair a session on “Sustainable Future”, with two well-known but extremely opposite personalities. On my left was a globally well-known environment activist talking about all the evils of chemical fertilizers and chemical pesticides. On my right was the President of Pesticide Association with equally strong views about how the chemical pesticides have greatly helped in feeding the hungry world. My task was further made difficult by a large lobby of green activists in the audience and also a number of seasoned industrialists with opposite views. Such a scenario is becoming increasingly common.

Composting is organic matter that has been decomposed and recycled as fertilizer and soil conditioner. It is a natural process of decomposition and recycling of organic material into humus rich soil amendment.

At the simplest level, the process of composting requires making a heap of organic material sprinkled with water which break down to humus after a period of weeks or months. However, modern bio composting is a multi-step, closely monitored process with measured inputs of water, air and carbon and nitrogen rich (in proper C:N ratio) materials.

Large quantities of crop residues are produced and if properly used, they can provide cost effective means for supplying organic matter, plant nutrients and improved soil health. The highly lignocellulosic nature of crop residues indicate their potential role in maintaining soil organic matter and enriching the soils with N-rich microbial biomass resulting from decompositions. However, their indiscriminate handling often burning leads to decline in soil health, air pollution and overall loss. Since most crop residues find use as feed and fuel, efficient recycling of the remaining amount can have very significant and positive effect.

Reducing the input costs in farming, especially agrochemicals and improving the yields of farm products in environmentally sustainable way, is one of the most important challenges. World over, the understanding of alternative eco-friendly inputs and intelligent integration of such products with the farming practices are the areas which need to be emphasized, understood and demonstrated. Our experience of working with farmers in different regions has convinced us that they all are looking for alternative, eco-friendly and cost effective inputs and the only way to convince them is practical demonstrations. 
Eco safe farming is a global challenge and needs combined efforts of NGO_s and farmers bodies, private and public sector industries and scientists in the institutions and universities. There are many challenges and many success stories and some typical once are listed here.

Indian Government has several developmental programmes to promote agriculture and rural sector. It includes Drought Prone Area Program, Antodaya Programme, Integrated Rural Development Programme, Hill Area Development Programme, Desert Development Programme, Intensive Jawahar Rojgar Yojna and Employment Assurance Scheme, Indira AwaasYojna, Integrated Waste Land Development Programme, National Food Security Mission, National Horticulture Mission, etc. Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) has the main focus to provide guaranteed employment for 100 days in a year to every rural household. Since 2014, the Swachh Bharat Abhiyan has been a major initiative by the Government of India.

Normally we associate our agriculture and food supply with farms and villages. The new trends of greener cities and urban and peri urban horticulture (UPH) are emerging very fast. Towns and cities in the world’s developing countries are growing at great speed. Ten years ago, an estimated 40 percent of the developing world’s population or 2 billion people lived in urban areas. Since then, their numbers have expanded twice as fast as total population growth, to more than 2.5 billion. By 2025, more than half the developing world’s population of 3.5 billion will be urban. Again most of the world’s fastest growing cities are in Asia and Africa with young population.

Since many decades environmentalists have warned of perils of chemicalised sports grounds, golf courses and cricket fields. They warn that our health is inextricably linked to the widespread use of toxic chemicals and also complain about the non-availability of safe alternatives.
Eco-sustainable sports fields must use the methods : 
    ·    That do not pollute
    ·    That are environment-friendly and effective
    ·    That economize on the use of water and energy

It is estimated that the country needs about 245mt of food grains, 30mt of sugar and jaggery, 7 lakh of tea, 1.7 lakh t of coffee, 10mt of vegetable oil and 17m bales of cotton. For realizing this, irrigated agriculture has to play an important role. To achieve this water use efficiency (WUE) in the irrigation sector has to be improved considerably as bulk of the available water is used in agriculture. But, with the ever-increasing population and industrialization problems, the demand for water by these sectors is bound to increase manyfolds in future. The requirement of water by different sectors during 2025 is estimated to be 105 m ham, which is 30 m ha m more than the present one. The share of water utilization for agriculture is expected to get reduced from the present percentage of 8~ to a value of 73 by 2025. Further, the demand for water for agricultural purposes is estimated to increase from 470 krrr’ to 740 krrr’ in a period of four decades (Table 1). During the same period there will be four­fold increase in the water demand for non-agriculture purposes.

The recent earthquake in Nepal brings back memories of 26th January 2001. While the nation was busy in celebrating Republic Day, an earthquake shattered Gujarat especially Kutch and Saurashtra regions. A large number of buildings and houses collapsed within moments. Thousands were injured and many lost their lives and many more became homeless.

Kutch received quick responses from all over the world and a large number of individuals, institutions, government and semi-government bodies, professional experts, religious and social organizations etc. sprang into action to bring back some normalcy in the lives. However, long-term rehabilitation program based on scientific planning is most vital after such disasters.

Bioshields offer barriers of vegetation, shrubs, small and big trees and if integrated as a well designed system they can greatly help our coastal as well as inland areas. Though primarily looked at for coastal regions, under a broader definition Bioshields can play important role in semi-desert areas, hills, etc. also.

Why Bioshield?

Bioshields or Biobarriers can make a major contribution in minimizing the effects of storms, cyclones and Tsunamis and at the same time offer short and long term ecological and livelihood benefits.
