The book contains suggestion on suitable crop rotations for salt-affected soils to maximize the productivity of lands and water under current climate and under climate change in 2030. This book discusses droughts and water scarcity, which are important issues related to natural phenomena and affected by climate variability and change. It calls for reassessing the prevailing crop structure in Egypt under rain fed irrigation in North Egypt and under surface irrigation in the Nile Delta and Valley.
Droughts affect rain fed agriculture, while water scarcity affects irrigated agriculture. The book investigates proposals for improving crop structure in these areas, taking into account the sustainability of water and soil resources. Further, it explores improved management options for crop production in both rain fed and irrigated agriculture. Lastly, it examines suggestions on more rational use of irrigation water in irrigated agriculture to conserve irrigationwater under present climate conditions and to help meet the anticipated demand under climate change conditions.

Offers a methodology for developing climate change scenarios with a low level of uncertainty using Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5) models and a regional climate model Provides the first-ever integrated assessment of climate change effects on rainfed agriculture in Egypt Presents different systems of crop intensification to increase land and water productivity under present and future climate conditions The book presents different systems of crop intensification to increase land and water productivity in clay soil and salt- affected soil under present and future climate conditions Includes supplementary material: sn.pub/extras

Autorentext
Samiha Ouda is a professor at the Soils, Water, and Environment Research Institute, Agricultural Research Center, Egypt; and has a background in agricultural economics, statistics and crop physiology. Professor Ouda has an impressive publication history of 64 papers and 2 book chapters on yield prediction using empirical models or simulation models, water stress mitigation, irrigation modeling under deficit irrigation and saline conditions, and assessing the impact of climate change on crops and farm net revenue. In 2006, Professor Ouda developed a simulation model called Yield-Stress for irrigation scheduling and prediction of yield and consumptive use of a number of crops under water, salinity and heat stresses.
