This book was released on 2007-04-23 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: This working paper presents the results of the Pakistan Component of the Rice-Wheat Consortium Project on ‘Sustaining the rice-wheat production systems of Asia’. Rice and wheat crops are main nsources of human food and substantially contribute to feeding livestock. The advent of the green revolution in the 1960s resulted in a tremendous increase in the production of these two cereal crops and the rice-wheat cropping system emerged as a very important source of food supply in South Asia. Recent symptoms of stagnant growth rates in productivity and the degradation of the resource base pose serious challenges to future food security and natural resources management in the region. The growing scarcity of water in the region

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.
Book Synopsis Understanding Hydrological Variability for Improved Water Management in the Semi-Arid Karkheh Basin, Iran by : Ilyas Masih
Download or read book Understanding Hydrological Variability for Improved Water Management in the Semi-Arid Karkheh Basin, Iran written by Ilyas Masih and published by CRC Press. This book was released on 2011-09-28 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study provides a hydrology based assessment of (surface) water resources and its continuum of variability and change at different spatio-temporal scales in the semi‐arid Karkheh Basin, Iran, where water is scarce, competition among users is high and massive water resources development is under way. The study reveals that the ongoing allocation planning is not sustainable and essentially requires reformulation, with consideration of spatio‐temporal variability and observed trends in the streamflows regarding flood intensification and decline in low flows. The development of innovative methods for quantification of the hydrological fluxes (i.e., regionalization of model parameters based on similarity of the flow duration curve and the use of areal precipitation input in the hydrological modeling) helped better understanding and modeling the basin hydrology. The investigation of scenarios for upgrading rain-fed areas to irrigated agriculture, using SWAT, recommends the promotion of in-situ soil and water conservation techniques. Conversion of rain-fed areas to irrigation causes significant reduction in the downstream flows, and requires additional considerations such as less development in the upper catchments, practicing supplementary irrigation and developing water storage. The knowledge generated is instructive for hydrological assessment and its use in water resources planning and management in the river basin context.
Book Synopsis Adoption and Impacts of Zero Tillage as a Resource Conserving Technology in the Irrigated Plains of South Asia by :
Download or read book Adoption and Impacts of Zero Tillage as a Resource Conserving Technology in the Irrigated Plains of South Asia written by and published by CIMMYT. 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 2024-02-27 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is one of the most pressing challenges confronting our global system today. The scientific community has clearly established that global temperatures are rising and the consequences of climate change may swiftly transition from an environmental risk to an economic threat. Agriculture sector is particularly vulnerable to changes in weather and climatic condition. Over 60% of the yield variability is chalked up to to climate change; significantly affecting food production and farmer income. Changes in climate affect the onset and duration of crop growing cycle, and the extent and duration of heat and water stress impact agriculture production. Moreover, it may trigger pest and disease outbreaks causing significant production losses. Small-scale farmers in rain-fed areas of Pakistan face the severe susceptibility to the challenges brought about by climate change. This vulnerability stems from their heavy dependence on traditional farming methods and their limited ability to adapt, exacerbated by their limited access to advanced technologies and high levels of poverty. Worldwide, crop yields from rainfed farming are approximately 50 percent less than those achieved through irrigated methods. In the absence of adaptation measures to cope with climate change, a potential decline of around 50 percent in rain-fed agricultural yields could potentially occur within the next 30-35 years. Promoting climate smart agricultural practices appears to be a dependable strategy for addressing risks posed by climate change.
Book Synopsis Pakistan: A cost-benefit analysis of puddled planted rice vs. direct seeded rice by : Rana, Abdul Wajid
Download or read book Pakistan: A cost-benefit analysis of puddled planted rice vs. direct seeded rice written by Rana, Abdul Wajid and published by Intl Food Policy Res Inst. 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.
Book Synopsis Soils, Plant Growth and Crop Production - Volume I by : Willy H. Verheye

This book was released on 2010-11-30 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils, Plant Growth and Crop Production is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Plants, and crops in particular, grow and develop through the uptake of water and nutrients by the root system in soils and their transformation into biomass through processes governed by photosynthesis. The quality and amount of products harvested from this biomass depend largely on the intrinsic properties of the soil, i.e. the moisture and nutrients made available for uptake by the roots. These volumes describe in a synthetic form the impact of the most important soil properties on general agronomy, crop production, cultivation methods, and yields, including the specific management aspects which take away some production constraints. Changes in general agronomy as a result of plant breeding, climatic change and competition between newly introduced crops are discussed. The three volumes with contributions from distinguished experts in the field discusses about soils, plant growth and crop production in several related topics. These volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Available in PDF, EPUB and Kindle. Book excerpt: The lives of more than a billion people depend on the answer! Thirty years ago, the Green Revolution changed the way agriculture was practiced on the Indo-Gangetic Plain (IGP). This valuable book critically analyzes and discusses the rice-wheat cropping system introduced at that time. The Rice-Wheat Cropping System of South Asia: Trends, Constraints, Productivity and Policy addresses the crucial question, ”Are the sustainability and productivity of this system in a state of decline?” The Rice-Wheat Cropping System of South Asia brings together information gathered from research institutions, government organizations, and farmer surveys. The analysis concentrates on the trends of rice-wheat cropping over time, paying special attention to the evidence of-and reasons for-changes in productivity. It also analyzes the impact of this regional system on soil fertility and water supplies, as well as the increasing demands for new and better fertilizers and pesticides. The Rice-Wheat Cropping System of South Asia looks at the problems that have arisen for both the rice and wheat phases, including: the need for changes in crop establishment techniques for crop diversification declining soil fertility changes in pest populations a host of water-management issues the need for policy redirection to sustain productivity growth the impact of global climate change sustainable improvements in productivity This informative book is an essential planning tool 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.

Book Synopsis Water, Food and Poverty in River Basins by : Myles J. Fisher
Download or read book Water, Food and Poverty in River Basins written by Myles J. Fisher and published by Routledge. This book was released on 2013-09-13 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional wisdom says that the world is heading for a major water crisis. By 2050, global population will increase from 7 billion to a staggering 9.5 billion and the demands this will place on food and water systems will inevitably push river basins over the edge. The findings from this book present a different picture. While it is convenient to visualize an inevitable global water and food crisis in which increasing demands result in increasing poverty, food insecurity and conflict, the reality is far more nuanced and revolves around the politics of equitable and sustainable development of resources. The first part of this book provides detailed insight into conditions of water flows within nine river basins. In the second part, authors summarize and re-analyze the outcome of the nine basins, providing a coherent global picture of water, water productivity and development. They assess the impacts of variations of these attributes on development and approaches for poverty alleviation, and explore the institutional factors that support or obstruct change. How people will manage river systems while protecting vital ecosystem functions will make the difference between catastrophe and survival. As Prof Asit Biswas points out, "... the world is facing a water crisis not because of physical scarcity of water but because of poor management practices in nearly all countries of the world." The book is based on the four years (2006-2010) of extensive research into the state of ten of the world’s major river basins carried out under the CGIAR Challenge Program for Water and Food’s Basin Focal Project. This book was published as a special issue of Water International.
