Book Description
This work presents models that characterize the relationships between quantity and quality of irrigation water application, and agricultural production and the environment. A comprehensive modeling approach addressing both the benefits of irrigation and the potential negative effects is introduced. Physical-biological concepts are combined with economic and engineering principles to demonstrate the usefulness of the model for analyzing various water management and policy issues. Decision makers on all levels should find the modeling approach interesting and useful in the management issues from the farm to national levels.

Subsurface Hydrological Responses to Land Cover and Land Use Changes

Subsurface Hydrological Responses to Land Cover and Land Use Changes PDF Author: Makoto Taniguchi
Publisher: Springer Science & Business Media
ISBN: 1461561418
Category : Science
Languages : en
Pages : 232

Book Description
Since human beings first appeared on the earth, we have changed land cover and land use for our own purposes, such as conveniences and high productivity. As a result of the land cover and land use changes, many serious environmental problems occur on the earth. Studying meteorological and hydrological effects of vegetation and land cover/use changes helps us to understand the environmental changes and problems happening near the earth surface, because the vegetation distributes the solar energy and water on the earth surface into atmosphere and geosphere. Subsurface hydrological responses to land cover and land use changes have drawn only regional environmental concerns, although global change caused by biosphere change has been studied in various scientific fields. The changes in land cover and land use alter water, solute and heat cycles in basins and elements of those balances, including evapotranspiration, groundwater recharge rate, discharge rates into rivers or ocean and soil moisture content, which are directly or indirectly related to the global environmental issues. Therefore, the changes in biosphere may substantially alter the subsurface hydrological system. For instance, increased groundwater recharge rates following clearing forest into grasses might be one consequence resulting in rising water tables and salinization.

The AquaCrop model – Enhancing crop water productivity

The AquaCrop model – Enhancing crop water productivity PDF Author: Salman, M., García-Vila, M., Fereres, E., Raes, D., Steduto, P.

Pages : 106

Book Description
Water resources are linked to the global challenges of food insecurity and poverty, as well as to climate change adaptation and mitigation. In line with the Sustainable Development Goals (SGD), FAO works towards several dimensions of sustainable development, including the promotion of coherent approaches to efficient, productive and sustainable water management, from farm to river basin scales. Accordingly, FAO is enhancing well-informed on-the-ground decision-making processes on water management through projects, knowledge advancement, information-sharing and tools development, such as AquaCrop, the FAO crop-water productivity model. This model assists in assessing the effects of environment (including atmospheric CO2 concentration) and management on crop production through the simulation of yield response to water of herbaceous crops. It is particularly suited to address conditions where water is a key limiting factor in crop production. In 2009, FAO officially launched AquaCrop, being the result of several years of collaborative work among scientists, water and crop specialists and practitioners worldwide, bringing together previously fragmented information on crop yields in response to water use and water deficit. AquaCrop has evolved over the different versions released since its first launch, but it always balances accuracy, simplicity and robustness. This has enabled it to remain faithful to its goal, i.e., to be a dynamic tool accessible to several types of users, mainly practitioner-type end users, in different disciplines and for a wide range of applications. In addition, AquaCrop may be considered a valuable tool by research scientists for analysis and conceptualization.

Prospects for Saline Agriculture

Prospects for Saline Agriculture PDF Author: R. Ahmad
Publisher: Springer Science & Business Media
ISBN: 9401700672
Category : Science
Languages : en
Pages : 453

Book Description
Saline land is a resource capable of significant production. Recent advances in research in breeding for salt tolerance in wheat, biotechnology in rice, and selection and rehabilitation of salt-tolerant plants are of economic importance in arid/saline conditions. This book gives some practical approaches for saline agriculture and afforestation, and describes examples of cultivating salt-tolerant/halophytic plants for commercial interest on salt-affected land or with highly salinized water in Australia, China, Central Asia, Egypt, Pakistan, and Russia. It also explores the possibilities of arid/saline agriculture and afforestation in UAE.
