Climate-Smart Water Management

This textbook focuses on the scientific and practical aspects of water management under changing climatic conditions. It covers:Basics of irrigation - importance history sources of water (rainfall reservoirs tanks groundwater) and key terminologies like field capacity wilting point and irrigation efficiency.Soil-water relations - how soil texture structure and porosity influence water retention movement and availability to crops.Measurement and dynamics - methods to measure soil moisture infiltration permeability evapotranspiration and factors affecting them.Irrigation scheduling and techniques - criteria for when and how to irrigate using methods such as check basin furrow ring basin and border strip systems.Drainage and efficiency - types of surface and subsurface drainage systems their design advantages and suitability for different soils.Water use efficiency (WUE) - how climatic genetic and management factors affect crop water productivity and strategies to enhance irrigation efficiency at the farm and project level.OverallIt promotes climate-smart sustainable and efficient irrigation practices to ensure food security and water conservation.
