Although the agricultural sector consumes more than 90% of the extracted water, its efficiency is lower than other sectors. Also, according to the population growth and critical role of food security, and the necessity to supply water to other sectors, an increasing pressure to save water, optimized consumption and increasing water use productivity in agriculture will occur in the future. Nowad...

the main purpose of rainfed farming is increasing the water productivity by applying suitable agricultural management including single irrigation (si) and panting time for wheat varieties. in order to study the si optimization and determination its optimal program, a field experiment was conducted as split-split plot based on a randomized complete block design with three replications for differ...

in arid, semiarid, and mediterranean climates, particularly in west asia and north africa, farmers face limited water resources and must develop irrigation management methods to increase crop production while reducing water use. this study examined methods to reduce irrigation water loss and increase maize water productivity at safiabad agricultural research center in dezful, iran in 2007 and 2...

Abstract- In this research, the performance measures of water equity and productivity have been optimizedin the entire DoroodzanIrrigation Network by using genetic algorithms. Results indicated thatirrigation water management improvement at field scale[increasing irrigation application efficiency (Ea) and water reduction fraction (WRF)] has much more impressive impact on raising the performance...

The Earth's atmosphere will continue to be enriched with carbon dioxide (CO2) over the coming century. Carbon dioxide enrichment often reduces leaf transpiration, which in water-limited ecosystems may increase soil water content, change species abundances and increase the productivity of plant communities. The effect of increased soil water on community productivity and community change may be ...

Agriculture accounts for most of the renewable freshwater resource withdrawals in Malawi, yet food insecurity and water scarcity remain as major challenges. Despite Malawi’s vast water resources, climate change, coupled with increasing population and urbanisation are contributing to increasing water scarcity. Improving crop water productivity has been identified as a possible solution to water ...
