1. Agroecology & System of Rice Intensification (SRI) — Lao PDR, Nepal Agroecology emphasizes sustainable farming that works in harmony with ecosystems, reducing reliance on chemical inputs and improving biodiversity. The System of Rice Intensification (SRI) is a flagship agroecological method that optimizes plant spacing, soil aeration, water management, and timing of inputs to boost rice yields sustainably. • Impact on Yields and Resource Use: In Lao PDR and Nepal, adoption of SRI has led to rice yield increases between 15% and 25%, outperforming conventional transplanting methods without increasing input costs significantly (FAO, 2021). This yield boost directly translates to higher food availability and incomes for smallholder farmers. Importantly, SRI reduces water use by about 30%, addressing water scarcity challenges faced in rainfed and drought-prone areas (IRRI, 2020). This efficiency stems from alternate wetting and drying practices rather than continuous flooding, improving

Diagnosis of parasitic infections is routinely done with conventional parasitological techniques as described earlier. However, when the parasitaemia is too low to be detected by the conventional methods as in subclinical infections and/or carrier animals advanced diagnostic tools are used for the early, sensitive as well as specific diagnosis.

Serological techniques

Diagnostic techniques used mostly in laboratories need various reagents and equipments to perform the test. However, a diagnostic kit is the extrapolation of the same method by packing it in a user friendly format, accompanied by all or most of the reagents required to perform the test and can also be done outside the laboratory or under field conditions.

INTRODUCTION

Assam is a heartland of indigenous groups. Since hundreds of years, many indigenous groups have been living in the state, maintaining their originalities in every sphere of life with difficulties. The tribal-indigenous groups constitute almost 12.4% of the total population of Assam. (Sentinelassam.com). Fishing is one of the major livelihood option of many indigenous fishers as the state is blessed with huge water resources with about 3.91 lakh hectare of water area in the form of rivers, beel, derelict water bodies and ponds and tanks. Besides swamps and low-lying areas, two major rivers and their tributaries have a high growth potential for fishing and could play a pivotal role in the socio-economic development and employment generation in the state. Indigenous fishers have developed a close and unique connection with the water resources and its environment in which they are depended for generation to generation for their livelihood. They have generated unique system of knowledge, innovation and skills relating to the uses and management of fishing activities. Over centuries, people have learnt how to get food and to survive in different environment. Farmers are very keen to observe the problems arising during fishing and seek solutions to adjust to their local environmental conditions. They continuously adapt and manage their fishing systems and in this way, they develop a rich storehouse of practical knowledge on their situation.

Foot and mouth disease (FMD) is the most contagious disease of animals and has a great potential for causing severe economic losses in susceptible cloven-hoofed animals. FMD has been classified as a Transboundary Animal Disease (TAD) which is highly contagious or transmissible and has the potential for very rapid spread, irrespective of national borders, and causing serious socio-economic consequences. FMD has constituted a recognised threat to the health of livestock for over 500 years and still remains a serious hazard to the productivity of animal populations throughout the world. The large numbers of virus serotypes and subtypes, the ease of transmission and the limited efficacy of vaccination make control complicated and difficult. Contribution of environmental variables for emergence and distribution of infectious diseases has long been recognized by many researchers. India is largely subject to four seasons: winter (January and February), summer (March to May), a monsoon (rainy) season (June to September), and a post-monsoon period (October to December). There are reports on effect of environmental parameters such as relative humidity, windspeed and air temperature on the spread of the disease. FMD is endemic and at a high prevalence in many countries in Africa, the Middle East and Asia and is also present in parts of South America. Europe, North and Central America, the Pacific nations and the Caribbean are free from the disease. FMD in India is the biggest impediment to growth of livestock sector. FMD outbreaks occur in India throughout the year. The outbreaks occurred round the year with maximum occurrence during October to March, and in May and June (Fig. 15.1). Foot and mouth disease is associated with an aphthovirus (family picornaviridae) which occurs as seven major serotypes: A,O,C,SAT1, SAT2, SAT3 and Asia1. FMD is characterized by fever, profuse salivation, vesicles in the mouth and on the feet and a drastic reduction in milk production; sudden death in young stock may occur (Radostits et al., 2006).

Greenhouse gas emission is likely to rise by 25-90% by 2030 relative to 2000 and the earth could warm by 3° C at the end of this century. Even with a temperature rise of 1-2.5° C, the Intergovernmental Panel on Climate Change predict serious disastrous effects, including reduction in crop yields in tropical and subtropical areas leading to increased risk of food shortage, spread of climate responsive diseases such as malaria, and an increased risk of extinction of 20-30% of all biodiversity present on earth (IPCC, 2007). Carbon dioxide is the most important among all greenhouse gases. Carbon sequestration may be defined as the process of removing C from the atmosphere and depositing it in a reservoir. It entails the transfer of atmospheric carbon dioxide, and its secure storage in long-lived pools (UNFCCC, 2007).

From the agroforestry point of view, carbon sequestration involves primarily the uptake of atmospheric CO₂ during photosynthesis and transfer of fixed carbon into vegetation and soil pools for ‘secure’ storage. It occurs in two major segments of agroforestry systems; aboveground and belowground. The total amount sequestered in each part differs greatly depending on a number of factors including the region, the type of system, site quality, and previous land-use (Nair, 2012). On average, the soil and aboveground parts are estimated to hold major portions, roughly 60 and 30%, respectively, of the total carbon stored in tree-based land-use systems (Lal, 2010). Sequestering CO₂ from atmosphere through natural techniques such as afforestation, reforestation, natural regeneration of forests and the adaptive agriculture is more economically and ecologically sound in increasing the carbon storage capacity of the terrestrial ecosystems (Dhyani, 2014). Although carbon sequestration through afforestation and reforestation of degraded natural forests has long been considered useful in climate change mitigation, agroforestry offers some distinct advantages (Murthy et al., 2013). The carbon in the aboveground and belowground biomass in an agroforestry system is generally much higher than the equivalent land use without trees. An agroforestry system has higher carbon sequestration potential than pastures or field crops (Kirby and Potvin, 2007).

Soil-rejuvenation power of legumes in crop rotations has been known in several parts of the world since ages. It is mentioned in the Indian agriculture of the Chalcolithic period (ca 1000 BC) (Raychaudhuri and Mira, 1993), in Chinese agriculture in the Han dynasty (ca 2nd century) (Hsu, 1980) and in Roman agriculture (White, 1970). Legumes can be ?tted in cropping systems in India in a number of ways, such as, a crop in a cropping system, a catch crop in an intensive cropping system, an intercrop and as a green manure. A brief discussion on these follows.

Introduction

The soil protozoa are unicellular and the simplest forms of animal life. Most of the protozoa are devoid of chlorophyll but transitional genera resemble the algae and possess chloroplasts containing chlorophyll pigments. The active life stage is commonly known as trophozoite phase where they feed and multiply but under adverse climatic conditions, they form resting stage or cyst, which develop a thick coating on the cell surface. Mostly, the protozoa multiply by longitudinal or transverse fission but some species reproduce sexually by fusion of two cells followed by exchange of genetic material between their nuclei and cell division.

Introduction

The generation of vast quantities of agricultural waste/ agri-waste is mainly due to crop residue and agro-industries unutilized products. Rice, wheat, sugarcane and fiber crops are the main components of agri-waste. In India, Wheat, rice and sugarcane are extensively cultivated and consumed by everyone, resulting in considerable agri-waste (Koul et al., 2022). Due to rapid population increase and food security for all, an extension of agricultural land, cropping patterns and multiple uses of the same crop field around the year are some main contributors to a significant rise in agricultural waste. About 380 million tons of agri-waste is produced in India annually, of which the contribution of paddy straw is about 130 million tons. 

In comparison to wheat and sugarcane residue, rice straw is easily degradable, and a significant part can be consumed as animal fodder, roof thatching, combustion, composting and soil mulching in rural areas; however, in urban areas, it creates issues (Mehta et al., 2023). Generally, with short intervals between rabi and kharif crops, controlling crop disease and pests and lacking environmental pollution concerns, farmers always manage their crop residue through stubble burning once or twice a year (Jeff et al., 2017). About 15 20 million tonnes of agri-waste will stubble burning every year in India, releasing vast amounts of smog and other air pollutants in the atmosphere and destroying several beneficial soil microbes, resulting in soil pollution. In India, the primary crop burning on the farm is cereals (58 %) and fiber crops (23 %); however, other crops, viz., sugarcanes, pulses, and oilseeds, can contribute the rest of the total (19%) stubble-burning of agro-waste (IARI 2012).

Introduction

In current scenario of COVID-19 pandemic, Agriculture and its allied sectorare the only sector which is contributed positive growth rate due to hard work and total devotion of farmers towards it in both first quarter of the financial year 2022-23. Farmers are the backbone of our country but face different challenges such as scarcity of land due to fragmentation, water sources, impassable roads, unavailability of better financial services and new technologies. Since a decade number of small and marginal farmers keeps on increasing. Due to the fragmented holding of land and improper management practices in farming inadequate access to market, making them agriculture more unviable. Government motive to double the farmers’ income in 2022-23 by addressing the challenges of farm sector. The government affirmed that farmer producer organizations (FPO) are the most appropriate institutional form around which farmers can mobilize and build their capacity to collectively leverage their production and marketing strength. However, majority of these located in rural areas and suffer from the problems like Inadequate Professional Management and Manpower, poor start-up capital, lack of technically skilled man power, ineffective capacity building training programmes. There is a need to find the solution and to need bring policy changes to handle this problem to empower our farmers and Indian economy by farmers produce organisation.

Introduction to Open Source Software in Video Editing In the digital age, video editing has become an essential skill, both for professionals in the media industry and for hobbyists. Open source software,
with its flexibility, affordability, and community-driven support, has emerged as a popular choice for video editing. Unlike proprietary software, open source software is freely available and can be modified and shared by users, allowing for constant updates and improvements.
Open source video editing tools provide a wide array of features, from basic trimming and cutting to advanced color grading, visual effects, and audio editing. These tools not only serve as cost-effective alternatives to commercial software but also encourage community involvement and learning.
Key Features of Open Source Video Editing Software
Open source video editors often include many features found in professionalgrade software, such as:
• Non-linear Editing (NLE): This allows users to access and edit any part of the video file in a non-sequential manner, giving greater flexibility.
• Multi-track Editing: Users can work with multiple video and audio layers, making it easier to combine elements for complex edits.
• Visual Effects and Transitions: Many open source editors support a variety of effects and transitions to enhance visual storytelling.
• Audio Editing Capabilities: These programs often provide basic audio editing tools and support for multi-track audio, essential for producing high-quality sound.
• Color Grading and Correction: Some open source editors allow users to adjust brightness, contrast, and color, ensuring a polished, professional look.

The Asia-Pacific region, home to a large proportion of the world’s agricultural producers and consumers, faces complex challenges: climate change, infrastructure gaps, market fragmentation, and inefficient supply chains that result in high post-harvest losses and limited farmer incomes. However, the region is witnessing rapid innovation across multiple fronts that promise to transform agri-food supply chains into more climate-resilient, transparent, inclusive, and efficient systems. These emerging opportunities align with regional sustainability goals and create pathways for economic growth and rural development. 7.1 Climate-Smart Infrastructure: Financing Low-Carbon and Resilient Agri Supply Chains Green Bonds for Solar Cold Rooms Vietnam’s Mekong Delta — a critical rice-producing region — is pioneering the issuance of green bonds to finance solar-powered cold rooms under the “One Million Hectares” low-carbon rice initiative

Sapota [Manilkara zapota (L.) P. Royen, (Manilkara achras (Mill.) Fosber] is a member of the family sapotaceae. It is a fairly slow growing and long-lived tree. It is valued for its delicious fruit in India, while in Guatemala, south East Mexico, British Honduras, chickle is commercially produced which is the main ingredient in preparation of chewing gum. Chickle is extracted from trunk and unripe fruits of the tree as white latex exudate. Although synthetic gums are primarily used, countries like Mexico, Venezula and Guatemala still grow sapota for chickle.

It is native to South Mexico as well as North East Guatemala. Manilkara species is found in forests throughout tropical America, which was introduced long ago followed by West Indies, Bahamas, Bermuda and Southern part of Florida mainland. Early in colonial times, it was carried to Phillippines, and later distributed to Malaysia and other countries in the tropics (Purseglove, 1974). It is not known when it was first introduced to India. Commercial cultivation was first taken up in Maharashtra during 1898 (Cheema et al., 1954). Future of sapota appears to be promising, since attention in this crop is enthusiastic from growers and consumers in many countries. Sapota is grown on commercial basis in India, Philippines, Sri Lanka, Malaysia, Mexico and Venezuela.

India is one of the largest producers of sapota in the world. Major states growing this fruit crop are Maharashtra, Gujarat, Andhra Pradesh, Karnataka, Tamil Nadu, West Bengal, Kerala, Uttar Pradesh, Punjab, Assam and Haryana. India’s production of sapota continues to grow up and there is an active research program in India with specific goals towards improving storage, transport and marketing strategies.

During last two decades significant advances have been made in diagnostic ultrasound .These advances have positively impacted on diagnostic imaging across all species of animals and have made ultrasound as an indispensable diagnostic modality in veterinary medicine. Since equines have been more a sport and pack animals, the ultrasound technique has long been utilized in the diagnosis of equine musculo-skeletal disorders. Recent years have witnessed its utility in the management of equine reproduction beside its use in the diagnosis of colic and other diseases.

Introduction

Agriculture is vital to the Indian economy in terms of job creation, with nearly half of the Indian population relying on agriculture and related activities for a living. A large proportion of the population, particularly in rural areas, is illiterate. The rural population, which is illiterate and ignorant, is unable to cope with the complexities of agricultural technology management. As a result, vocational training and technology dissemination are few viable options for increasing production efficiency and achieving rapid and sustainable agricultural development. The State of Odisha derives more than a quarter of its revenue from agriculture. More than 40% of the people in the state of Odisha depend on farming as their primary source of income and way of life, making up more than 53% of the state’s workforce. whereas agricultural technology has developed into a logical extension of the traditions, conventions, knowledge, and skills that date back to the early days of human civilization and have continued to evolve over time. It was not just agriculture that produced food or other biological means; rather, it essentially presented a wide range of traditional values to make it abundantly evident that “TECHNOLOGY and TECHNIQUE” are the cultural means to satisfy the biological as well as social demand for life. To provide the necessary acceleration to the agricultural development, Agricultural Technology Management Agency (ATMA) Scheme was launched during 2005-06 in order to enrich farmer’s skills, knowledge and competency several developmental programmes/projects, in agriculture and allied sectors. In the state Odisha, a district level autonomous institute has taken the main responsibility of all technology dissemination activities at district level for development of farmers and farm women through its bottom –up approach. During 2010 the reforms made in ATMA project and farm persons were given due importance to its multifarious activities like training, demonstration, information support, input supply, market-oriented facilities, linking credit and exposure visit etc. These multi-purpose activities provide ample opportunities for the farm communities and makes the resources accessible for them. Additionally, ATMA served as a link between individuals in need and those with the means necessary for undergoing rapid technological change. It is also critical to evaluate various stakeholders of ATMA in order to enhance both its organisational and functional approach. This includes various parameters such as efficiency of skilled professionals of ATMA, availability of resources and feedback from farmer beneficiaries among other factors.

Introduction

Agriculture has historically been the primary source of income in India. It has the potential to alleviate poverty, increase income, and enhances food security for 80% of both the world’s poor and people who reside in rural areas primarily work in agriculture. One of the most effective strategies to eradicate extreme poverty, increase shared prosperity, and feed an estimated 9.7 billion people by 2050 is agricultural development. Compared to other modes, the agro - based sector’s progress is two to four times more successful in enhancing the earnings of the poorest people (www.worldbank.org).

Nearly 5 billion hectares, or 38% of the world’s land surface, is used for agriculture. Around one of this is devoted for farming, and the remaining two thirds are pastures and meadows for grazing animals. Over 10% of cropland is assigned to permanent crops like cocoa plantations, oil palm plantations, and fruit tree orchards. Yet another 21% of land is primed for irrigation, a crucial agricultural land management technique.
