Irrigation is one of the most important human activities sustaining civilization. On average, irrigated crop yields are double those from unirrigated land. It has been estimated that to meet the needs of the 8 billion population by 2025, the irrigated area must expand more than 20% and irrigated crop yields must improve by 40% ...
In many parts of the world, this scarcity significantly affects crop yield, crop quality, and, consequently, human quality of life. This important volume presents the ...
Understanding the mechanisms by which plants tolerate attack by pathogens, herbivores, or endure abiotic stress is a crucial part of learning how to enhance plant productivity and crop yields in the face of dwindling global agricultural resources. This book deals with the ability of plants to tolerate such attacks and stresses, and examines in detail various ...
Plant stress caused by drought and salinity are among the major constraints on crop production and food security worldwide. Breeding programs to improve crop yield in dry and saline environments have progressed slowly due to our limited understanding of the underlying physiological, biochemical, developmental, and genetic mechanisms that ...
Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped land. As such, irrigated agriculture is a productive user of resources; both in terms of yield per cropped area and in yield per volume of water consumed. Many irrigation projects, however, use (divert or withdraw) much more water than ...
Six Inches of Soil the film and this companion book is the inspiring story of British farmers standing up to the industrial food system and transforming the way they produce food – to heal the soil, benefit our health and provide for local communities. How has it come to this point in our history that we hardly value the food we eat and the soil that it’s grown in? How is it that we ...
A deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil ...
As interest in global climate increases, an understanding of the impact of major weather patterns such as El Nino grows in importance. This special publication takes an international approach to explore the impacts of climate variability on crop production and the potential of using seasonal climate forecasts for enhancing agricultural ...
The survival and success of all living organisms are determined by energy and matter transfers between the upper layers of the soil profile and the lowest levels of its atmosphere. In this monograph 50 experts collaborated to develop 23 chapters detailing the role that micrometeorology plays in crop production systems and terrestrial ...

"Crop Modeling and Decision Support" presents 36 papers selected from the International Symposium on Crop Modeling and Decision Support (ISCMDS-2008), held at Nanjing of China from 19th to 22nd in April, 2008. Many of these papers show the recent advances in modeling crop and soil processes, crop productivity, plant architecture and climate change; the rests describe the developments in ...
This book addresses the responses of plants to salinity. Although salinity is a common environmental factor for marine organisms, for the majority of land plants high soil salinity is an environmental constraint that limits growth, productivity, and normal plant functions. Salinity is particularly widespread in arid/semiarid climates where crop production depends on irrigation. A comprehensive ...
Agriculture is a crucial component of the economies of many of the countries in transition from a centrally-planned to a market economy and the sector is by no means immune to the environmental and socioeconomic problems confronting the countries as a whole. The concept of sustainable development provides a convenient framework for the formulation of government environmental policy for such ...
Sulfur is one of the four major essential elements necessary for the plant life cycle. Its assimilation in higher plants and its reduction in metabolically important sulfur compounds are crucial factors determining plant growth and vigor and resistance to stresses. The range of biological compounds that contain sulfur is wide. The information on sulfur assimilation can be exploited in tailoring ...

Enormous increases in agricultural productivity can properly be associated with the use of chemicals. This statement applies equally to crop production through the use of fertilizers, herbicides and pesticides, as to livestock production and the associated use of drugs, steroids and other growth accelerators. There is, however a dark side to this picture and it is important to balance the ...
Since 1985, the University of Hohenheim, Germany, in collaboration with the ICRISAT Sahelian Center, Niger, has pursued the development of improved agricultural systems for smallholder farmers in the fragile agricultural ecosystem of the West African Sahel. Wind erosion is one of the constraints that limits crop production in the region and was therefore a major focus of research. In this ...
