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.

Existing positive as well as negative interactions among the members of the society determine the communication structure, leadership and technology diffusion pattern within the given social system. Sociometry is a method for gathering and analyzing data on communication choice and interaction pattern of individuals, within a group in order to identify communication structure and pattern.

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.

Data collected by using different data collection methods remain meaningless until it is screened, cleaned, coded, analyzed and summarized. Data cleaning and screening mostly come under the purview of statistical logics and techniques hence not dealt with in this practical guide. Since these aspects will be dealt by the statistical experts from the allied statistical wings. Presuming that students are aware about data cleaning and screening, we will proceed further with data coding.

Hypothesis testing is the statistical procedure used in order to accept or reject statistical null hypotheses. One of the major purpose for which we formulate the hypothesis is, to test the statistical significance of the relation, difference or variation etc. among given sample/s at a given point of time or at different time points.

Based on the nature and purpose of the content, there are numerous classes of scientific communications. Theses represent the class of research communications that are of great importance to the students. Thesis is part and parcel of the master’s and doctoral programme in almost every academic institution. In some institutions, even the bachelor students are expected to submit their brief report on project.

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.

Present study was conducted in an Eastern Indian State ‘Chhattisgarh’, which was purposively selected keeping in view the importance of SHG movement in empowering rural poor in Eastern Indian States, home of the largest proportion of population below poverty line. To have in-depth micro level analyses, one district of Chhattisgarh was randomly selected, which happened to be the Kanker district.

We mean sustainable of agriculture as preservation of productivity of land for a long period. This requires deviation from present methods of cultivation. The deviation needs knowledge about ecological process. At present we mean agriculture in association with terms like, high-tech, bio-tech and info-tech. Our traditional farming system or conventional farming system essentially means sustainable agriculture.

Women constitute 50% of our population. Their contribution to farming needs no emphasis as they are integral part of it. Women have developed farming in our country and contributed immensely for growth and maintenance of agriculture as a whole. But majority of them are not fully aware of sustainable agriculture in scientific terms although they practice it. Surveys and observations reveal that women are in favor of traditional agriculture and feel that traditional farming is more sustainable than the present one.

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).

Sustainable agriculture requires sincere attempt by the farmers to be sustainable in their approach. The practices are neither new nor difficult. But the minds of the farmers are so much inclined to inorganic farming that it is not so easy to divert their minds for sustainable agriculture.
