Book Description
In Pakistan, wheat being the staple diet is the most important crop and cultivated on the largest acreages. It contributes 14.4 percent to the value added in agriculture and 3.0 percent to GDP. Over the past three decades, increased agricultural productivity occurred largely due to the deployment of high-yielding cultivars and increased fertilizer use. With the introduction of semi-dwarf wheat cultivars, wheat productivity has been increased in all the major cropping systems representing the diverse and varying agro-ecological conditions. Improved semi-dwarf wheat cultivars available in Pakistan have genetic yield potential of 6-8 tones per hectare whereas our national average yields are about 2.7 t/ha. A large number of experiment stations and on-farm demonstrations have repeatedly shown high yield potential of the varieties. There are progressive farmers of irrigated area who are harvesting 6 to 7 2.7 t/ha. However, farmers yield ranges 0.5 to 1.3 t/ ha depending on the amount of rainfall in rainfed areas and in irrigated areas it ranges from 2.5 to 3 t/ ha depending upon the amount of water available and other factors.

Book Description
This volume discusses the need to adopt Climate-Resilient Agriculture (CRA) practices to address the increasing global impact that climate change has on agricultural productivity and agriculture-dependent communities. This approach applies technological, policy and economic measures to achieve sustainable agricultural growth in the sectors of grain, fruit, vegetable, fiber, feed, livestock, fisheries and forestry, with the ultimate goal of adapting and building resilience to climate change. The book also uses GIS, crop modeling and remote sensing techniques for future climate resilience applications in agriculture, and covers pest control measures that avoid the use of pesticides to boost crop and livestock productivity for improved food security. The book will be of interest to researchers and students in environmental science, climate science, sustainability and agriculture, as well as policy makers and environmental organizations.

Book Description
This book offers perspective on climate change impacts on developing nations from scholars within those nations, primarily focusing on agriculture. Throughout three parts containing a total of over twenty chapters from scholars in developing countries, it aims to offer guidelines for researchers, policymakers, and farmers themselves on how developing countries can achieve sustainable food security and continue development on a sustainable basis. Part I covers climate change concepts and issues for developing countries; Part II offers chapters dealing with social issues surrounding climate change and agriculture; Part III addresses practical policies that can be implemented to work toward achieving the goals described above. Agriculture is a key sector in developing countries in terms of economic growth and social well-being. Adapting and building resilience to climate change means increasing agricultural productivity and incomes and reducing greenhouse gases emissions. This volume represents an effort toward collecting knowledge on the technical, policy and investment measures to achieve sustainable agricultural growth in the sectors of grain, fruit, vegetable, fiber, feed, livestock, fisheries and forest under climate change in one place.

Book Description
The results indicated that regional dryland wheat production will increase in the future, but with spatial variation and uncertainty related to future weather projections. Improvement in yield will provide opportunities for intensification of cropping systems and may lead to some reduction of fallow use. Total GHG emissions (nitrous oxide and carbon dioxide from reduced SOC stocks) had a decreasing trend while N2O emissions accounted for a larger portion of total GHG and the relative contribution had an increasing trend toward the 2070s since SOC losses were lower.

Book Description
Catastrophic floods, droughts, and cyclones have plagued Pakistan in recent years. The 2010 flood killed 1,600 people and caused around $10 billion in damage. The 2015 Karachi heat wave led to the death of more than 1,200 people. Climate change-related natural hazards may increase in frequency and severity in the coming decades. Climatic changes are expected to have wide-ranging impacts on Pakistan, affecting agricultural productivity, water availability, and increased frequency of extreme climatic events. Addressing these risks requires climate change to be mainstreamed into national strategy and policy. This publication provides a comprehensive overview of climate change science and policy in Pakistan.

Book Description
The report computes different components of potential crop water demand at the canal command level in Indus Basin. Major contribution is update of water demand based on several years of climate data, which improves the estimation of reference evapotranspiration for developing refined crop coefficients based on the latest cropping patterns. The water demands of major crop and fully developed standard unit for each canal command is presented for direct comparisons and adjustments, if required. The report is part of Indus Basin performance study, which aims to identify the scope for integrated land and water management by evaluating current practices to propose sustainable alternatives.

Book Description
Achieving food security and economic developmental objectives in the face of climate change and rapid population growth requires systems modelling approaches, for example in the design of sustainable agriculture farming systems. Such approaches increase our understanding of system responses to different soil and climatic conditions, and provide insights into the effects of various variable climate change scenarios, providing valuable information for decision-makers. Further, in the agricultural sector, systems modelling can help optimise crop management and adaptation measures to boost productivity under variable climatic conditions. Presenting key outcomes from crop models used in agricultural systems this book is a valuable resource for professionals interested in using modelling approaches to manage the growth and improve the quality of various crops.
