Book Description
Conservation agriculture systems have long-term impacts on livelihoods, agricultural production, gender equity, and regional economic development of tribal societies in South Asia. This book presents South Asia as a case study, due to the high soil erosion caused by monsoon rainfall and geophysical conditions in the region, which necessitate conservation agriculture approaches, and the high percentage of people in South Asia relying on subsistence and traditional farming. The book takes an interdisciplinary approach to analyse systems at scales ranging from household to regional and national levels.

Book Description
This paper addresses the challenge of increasing the rate of varietal turnover to prevent depreciation of improved cultivars over time. It examines the supply of and demand for improved cultivars of wheat in India to illustrate this challenge in a unique manner, combining national-level data on breeder seed production with primary data on cultivar adoption. The analyses show that the rate of varietal turnover for wheat has slowed in India from an average of 9-10 years a decade ago to 13-14 years in 2010. By focusing on a sample of farmers and villages in Haryana, where seed and information networks are relatively well developed, the study finds that wheat farmers still prefer cultivars that were released 9-10 years ago.

Book Description
This book explores the sustainability aspect of organic and conventional farming systems, which is commonly categorized into three sub-aspects: social, environmental and economic. The social structure of a given area, organic friendly technologies, soil properties, crop diversification and income are the elements chosen for comparison, and are analyzed using descriptive and statistical methods. In addition, the book assesses the current status of the local organic market in Nepal and field experiments involving the use of various organic means to achieve better production for selected vegetables. Determining the benefits and/or challenges of organic and conventional farming is important to determining the most viable type of farming in the long term, but can be greatly impacted by a given area’s specific characteristics (social, environmental, political, etc.), which is why this study focuses on a specific location: the Chitwan district of Nepal, where group conversion to organic farming has existed alongside conventional farming for years. This book offers a useful guide for both practitioners and academic researchers who are interested in organic farming and food security, particularly in developing countries.

Book Description
Agriculture in Eastern Europe and Central Asia is diverse, and has great potential to revitalize the economy of the countries in the region via improved productivity (efficiency) and higher total yield for food, fodder and fibre crops. Conservation agriculture can rise to the major challenge of making sustainable intensification of production systems a reality. In order for farmers to transition to appropriate sustainable production systems, the provision of an adequate enabling environment and access to knowledge and services, including extension, mechanization, inputs and market intelligence, are crucial. This Guide is designed to provide coherent technical tools to Farmer Field Schools and extension service facilitators of conservation agriculture. Furthermore, the Guide is suitable for use within universities’ agriculture curricula.

Book Description
Rice-maize (R-M) cropping systems have emerged in recent years on 3.5 million hectares in Asia in response to the increasing demand from a rapidly expanding human population for rice and livestock products. They are rapidly spreading in southern and northeastern India and Bangladesh, driven by the rising demand for maize by the poultry and fish sectors and the tightening world export-import markets. The recent development of short-duration rice varieties and maize hybrids with improved drought tolerance is also providing opportunities for the expansion of R-M systems into areas of South Asia with insufficient irrigation or rain for continuous rice cultivation. Agroecologically, R-M systems have the potential to expand into broad climatic zones across Asia. Because strong economic multipliers exist between food production and feed and livestock production, more diversified cropping systems are also likely to become a key engine for economic growth in rural areas of Asia. This will contribute to more diversified diets, improved human nutrition, reduced poverty, and greater investment in other aspects of quality of life such as education and health care. R-M systems will also provide new business opportunities for the local agribusiness sector, including hybrid seed production and marketing, the fertilizer sector, the agricultural machinery sector, and the grain marketing and livestock feed-processing sector. Recognizing the importance of diversifying cropping systems in Asia and the need for system-level research to support new opportunities for agricultural development, IRRI and CIMMYT scientists, in collaboration with NARES partners, have recently begun work on R-M systems in many countries of Asia. This report contains information on a strategic assessment of R-M systems for 29 selected sites representing diverse soils, climate, and agroecosystems across nine countries in Asia (Bangladesh, China, India, Indonesia, Nepal, Pakistan, the Philippines, Thailand, and Vietnam). Conducted jointly by IRRI and CIMMYT, the process involves regional and site-level biophysical assessment, supported by socioeconomic evaluation using economic data at the regional level and some microeconomic data. Biophysical assessment includes agroecosystem characterization of R-M systems, analysis of historical daily climatic data, and regional-level prediction of yield potential for the 29 sites. The study then provides a detailed analysis of 10 selected sites to understand existing cropping systems, identify alternative potential systems, and explore measures to optimize these. The Cereal Systems Initiative for South Asia (CSISA), a project funded by the Gates Foundation and USAID in Bangladesh, India, Nepal, and Pakistan, was launched in early 2009. It now provides an overall strategy and a new umbrella for contributing new science and technologies to accelerate short- and long-term cereal production growth in South Asia's most important grain baskets. It builds on technologies developed and lessons learned from the Rice-Wheat Consortium (RWC) and many other investments in agricultural R & D by both the public and private sector. Through creating and facilitating innovative and effective public-/private-sector partnerships in key "hubs" in South Asia. CSISA will boost the deployment of existing varieties, hybrids, crop- and aquaculture-related management technologies, and market information. The results from the strategic assessment of R-M systems are already being used in several CSISA hubs.

Book Description
This book addresses an important topic of food security in South Asia with specific reference to climate change. Of the 1 billion food insecure people in the world, more than 30% are in South Asia. The problem of food insecurity may be exacerbated by the projected climate change especially because of the water scarcity caused by rapid melting of the glaciers in the Himalayas and increase in variability in monsoonal rains and frequency of extreme events. Furthermore, large populations of Bangladesh and other coastal regions may be displaced by sea level rise. Thus, this volume addresses recommended land use and soil/water/crop/vegetation management practices which would enable land managers to adapt to climate disruption by enhancing soil/ecosystem/social resilience. In addition to biophysical factors, this book also addresses the issues related to human dimensions including social, ethnical and political considerations.
