This book was released on 2007 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent stagnation of productivity growth in the irrigated areas of the Indo-Gangetic Plains of South Asia has led to a quest for resource conserving technologies that can save water, reduce production costs and improve production. The present synthesis of two detailed country studies confirmed widespread adoption of zero tillage (ZT) wheat in the rice-wheat systems of India's Haryana State (34.5% of surveyed households) and Pakistan's Punjab province (19%). The combination of a significant "yield effect" and "cost-saving effect" makes adoption worthwhile and is the main driver behind the rapid spread and widespread acceptance of ZT in Haryana, India. In Punjab, Pakistan, adoption is driven by the significant ZT-induced cost savings for wheat cultivation. Thus, the prime driver for ZT adoption is not water savings or natural resource conservation but monetary gain in both sites. Water savings are only a potential added benefit. ZT adoption for wheat has accelerated from insignificant levels from 2000 onwards in both sites. Geographic penetration of ZT is far from uniform, suggesting the potential for further diffusion, particularly in Haryana, India. Diffusion seems to have stagnated in the Punjab study area, and further follow-up studies are needed to confirm this. The study also revealed significant dis-adoption of ZT in the survey year: Punjab, Pakistan 14 percent and Haryana, India 10 percent. Better understanding the rationale for dis-adoption merits further scrutiny. Our findings suggest that there is no clear single overarching constraint but that a combination of factors is at play, including technology performance, technology access, seasonal constraints and, particularly in the case of Punjab, Pakistan, the institutional ZT controversy. In terms of technology performance, the relative ZT yield was particularly influential: dis-adopters of ZT reporting low ZT yields as a major contributor to farmer disillusionment in Punjab, Pakistan and the lack of a significant yield effect in Haryana, India. In neither site did the ZT-induced time savings in land preparation translate into timelier establishment, contributing to the general lack of a yield increase. Knowledge blockages, resource constraints and ZT drill cost and availability all contributed to nonadoption. This suggests that there is potential to further enhance access to this technology and thereby its penetration. The study highlights that in both Haryana, India and Punjab, Pakistan ZT has been primarily adopted by the larger and more productive farmers. The structural differences between the adopters and non-adopters/dis-adopters in terms of resource base, crop management and performance thereby easily confound the assessment of ZT impact across adoption categories. This calls for the comparison of the ZT plots and conventional tillage plots on adopter farms. ZT-induced effects primarily apply to the establishment and production costs of the wheat crop. Both the Haryana, India and Punjab, Pakistan studies confirmed significant ZT-induced resource-saving effects in farmers' fields in terms of diesel and tractor time for wheat cultivation. Water savings are, however, less pronounced than expected from on-farm trial data. It was only in Haryana, India that there were significant ZT-induced water savings in addition to significant yield enhancement. The higher yield and water savings in Haryana, India result in significantly Abstract vi higher water productivity indicators for ZT wheat. In both sites, there are limited implications for the overall wheat crop management, the subsequent rice crop and the rice-wheat system as a whole. The ZT-induced yield enhancement and cost savings provide a much needed boost to the returns to, and competitiveness of, wheat cultivation in Haryana, India. In Punjab, Pakistan, ZT is primarily a cost-saving technology. Based on these findings the study provides a number of recommendations for research and development in South Asia's rice-wheat systems.

This book was released on 2009-05-07 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is the main occupation in India and about 75% of its population depends directly or indirectly on agriculture for their livelihood. It is the dominant sector that contributes 18% of the gross domestic product. Thus, agriculture is the foundation of the Indian economy. The maximum share of Indian exports is also from the agriculture sector. As the population of the country is increasing trem- dously, approximately at the rate of 19 million every year over the existing popu- tion of more than 1 billion (approximately 1. 18 billion), the food grain production must necessarily be increased. This can be done by increasing crop production to match the population growth rate of 2. 2% per annum, which is expected to stabilize at 1. 53 billion around 2050. There is no doubt that the Green Revolution in India during the late 1960s brought self-sufficiency in food grain production, mainly through the increase in rice and wheat crop yields – the two main crops of the country which play an important role from food security point of view. However, the excessive use of fertilizers and pesticides, and the neglect of organic manures for these crops, has resulted in the deterioration of physical, chemical and biological health of the ri- and wheat-growing soils. Owing to the deterioration of the health of these soils, the productivity of the rice–wheat cropping system has now either got reduced or in some places has become constant for the last decade.

Available in PDF, EPUB and Kindle. Book excerpt: Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

This book was released on 2018-06-21 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: FAO’s best-selling 2011 publication, Save and Grow, proposed a new paradigm of agriculture, one that is both highly productive and environmentally sustainable. This new book looks at the application of “Save and Grow” practices and technologies to production of the world’s key food security crops – maize, rice and wheat. With examples drawn from developing countries worldwide, it shows how eco-friendly farming systems are helping smallholder producers to boost cereal yields, improve their incomes and livelihoods, conserve natural resources, reduce negative impacts on the environment, and build resilience to climate change. The book will be a valuable reference for policymakers and development practitioners guiding the transition to sustainable food and agriculture.

Book excerpt: Globally, significant work has been done to enhance our current understanding of the nutritional and anti-nutritional properties, processing, storage, bioactivity, and product development of wheat, opening new frontiers for further improvement. Wheat Science: Nutritional and Anti-Nutritional Properties, Processing, Storage, Bioactivity, and Product Development addresses the topics associated with the advances in understanding the wheat biochemical, nutritional, and rheological quality. Improving crop varieties by either conventional breeding or transgenic methods to obtain nutritionally enhanced crops has the advantage of making a one-time investment in research and development to have sustainable products. Features: Includes topics associated with the nutritional composition and anti-nutritional properties Addresses the effects of different processing technologies on flour yield and end products Reviews the effects of storage on nutritional, baking and rheological quality, organoleptic quality, etc. Processing and storage technologies have impacted the nutritional quality and the bioavailability of nutrients in wheat. Due to its peculiar grain protein composition, especially gluten protein, wheat has extensive usage in making numerous end products, eaten round the clock. Researchers have demonstrated a significant effect of alteration of flour-processing technologies on the rheological quality of end products. This book provides a holistic understanding and covers recent developments of wheat science under one umbrella. Emphasis is placed on current trends and advances in nutritional and anti-nutritional properties, processing, storage, bioactivity, and product development. Additionally, efforts have been made to compile the available information on the application of different ingredients of wheat in the industry and pharma sectors.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines the current situation, levels of adoption, management practices, and the future outlook of conservation agriculture in India, and also in other tropical and subtropical regions of the world. While conservation agriculture is proposed as an important means to combat climate change, improve crop productivity and food affordability, and to protect the environment, the adoption of conservation agriculture in India, and south-east Asia more broadly, has been slow. This volume reflects on the current status of conservation agriculture in India, asking why adoption has been slow and putting forward strategies to improve its uptake. The chapters cover the various aspects of crop management such as soil, water, nutrients, weeds, crop residues, machinery, and energy, in a range of environments, including irrigated and rainfed regions. The impact of climate change and the economic considerations behind the adoption of conservation agriculture are also discussed. The volume concludes by discussing the future outlook for conservation agriculture in India, in particular drawing out parallels with other tropical and subtropical regions of the world. This book will be of great interest to students and scholars of conservation agriculture, sustainable agriculture, crop and soil management, and environmental and natural resource management.

Available in PDF, EPUB and Kindle. Book excerpt: The lives of more than a billion people depend on the answer! This valuable book surveys the problems of the rice-wheat cropping system practiced on the Indo-Gangetic Plain (IGP). Introduced at the time of the Green Revolution, it transformed agriculture and produced thirty years of bumper crops. The Rice-Wheat Cropping System of South Asia: Efficient Production Management offers scientific analysis of the aftereffects of this intense cropping. The Rice-Wheat Cropping System of South Asia: Efficient Production Management focuses on the questions of soil depletion, pest infestation, and soil alkalinity as elements of declining productivity. Along with clear charts, maps, and graphs, it provides practical suggestions for improving and maintaining the productivity of this irreplaceable farmland. The Rice-Wheat Cropping System of South Asia looks at the problems that have arisen for both the rice and wheat phases, including: depletion of micronutrients degradation of major nutrients from unbalanced fertilization practices infestations of nematodes increasing soil alkalinity as a result of irrigation It also suggests solutions for maintaining productivity, including: integrated pest management sustainable agriculture micronutrient fertilizers This informative book and its companion volume, The Rice-Wheat Cropping System of South Asia: Trends, Constraints, Productivity and Policy, are essential planning tools for agronomists, policymakers, and agroeconomists. It is also a useful reference for anyone interested in the problems of famine and intensive cropping not only in South Asia but in the world.

This book was released on 2024-03-04 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice-wheat, a major cropping system of Pakistan, is vulnerable to the negative impacts of climate change, manifesting in the form of yield reduction. Among various crops, rice is often identified as the most at-risk food crop which is prone to a substantial drop in yield because of climate change and weather variations. It is estimated that the yield of wheat and rice may decline by 14.7 percent and 20.5 percent, respectively, by 2050 due to changes in climate. It is expected that Pakistan could potentially incur a climate change-related loss of $19.5 billion by 2050 due to reduced wheat and rice crop yields due to water scarcity, rising average temperatures, and less precipitation. Research indicates that if current climate change patterns persist and farmers do not adopt suitable climate resilient methods, rice production in Pakistan could decline by as much as 36 percent by the year 2099.

This book was released on 2010-01-01 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world has made enormous progress in the past 50 years toward eliminating hunger and malnutrition. While, in 1960, roughly 30 percent of the world's population suffered from hunger and malnutrition, today less than 20 percent doessome five billion people now have enough food to live healthy, productive lives. Agricultural development has contributed significantly to these gains by increasing food supplies, reducing food prices, and creating new income and employment opportunities for some of the world's poorest people.This book examines where, why, and how past interventions in agricultural development have succeeded. It carefully reviews the policies, programs, and investments in agricultural development that have reduced hunger and poverty across Africa, Asia, and Latin America over the past half century. The 19 successes included here are described in in-depth case studies that synthesize the evidence on the intervention's impact on agricultural productivity and food security, evaluate the rigor with which the evidence was collected, and assess the tradeoffs inherent in each success. Together, these chapters provide evidence of "what works" in agricultural development.
