Supplemental Irrigation: A Highly Efficient Water‐Use Practice - 2nd Edition
Rain-fed agriculture accounts for about 80% of the world’s farmland and two-thirds
of global food production. Despite the higher risks and generally lower
productivity compared to irrigated areas, rainfed agriculture will ...
Water and land productivities of wheat and food legumes with deficit supplemental irrigation in a Mediterranean environment
Selecting appropriate crops and applying deficit irrigation can help increase water productivity in waterlimited
regions such as the Mediterranean. The objective of this study was to develop water production
functions of ...
The role of limited irrigation and advanced management on improving water productivity of rainfed wheat at semi-cold region of upper Karkheh River Basin, Iran
In order to evaluate the role of a limited irrigation (LI) and agronomic management on
improving rain water productivity, a field study was conducted during 2005-08 winter cropping
seasons of wheat at multiple farms across ...
A Participatory GIS Approach for Assessing Land Suitability for Rainwater Harvesting in an Arid Rangeland Environment
The dry rangelands of West Asia and North Africa are fragile and severely degraded due to low rainfall and mismanagement of natural resources. Rainwater harvesting (RWH) interventions are used to increase soil moisture ...
Impact of Expanding Supplemental Irrigation in the Upper Karkheh River Basin (Iran) on Downstream Flow
The Karkheh River Basin (KRB) of Iran has a semi-arid to arid climate and suffers from low rainfed agricultural productivity. Supplemental irrigation (SI) is recommended in the upper KRB to increase crops yields and water ...
Water Resources of the Karkheh River Basin: Hydrology, Runoff, and Water Balance
The project - ‘Strengthening Livelihood Resilience in the Upper Catchments of Dry Areas by Integrated Natural Resources Management’ was undertaken in the Karkheh River Basin (KRB) of southwest Iran, from August 2005 to ...
Spatial and Temporal Analyses of Water Quality in the Dhrabi Watershed of Pakistan: Issues and Options
Monitoring water quality is important for maintaining a healthy watershed, but it is mostly ignored in watershed planning
and management. In the Dhrabi watershed of Pakistan, the quality of surface water was monitored at ...
The Fallacy of Irrigation Modernization
Many countries are keen to move away from traditional surface irrigation systems to more modern and efficient systems such as drip and sprinkler irrigation. Surface irrigation systems are less efficient in terms of water ...
Assessment of wheat yield gap in the Mediterranean: Case studies from Morocco, Syria, and Turkey
The WANA region has 137 million hectares of arable land of which 35 million hectares are sown to wheat, mostly grown under rainfed conditions with productivity in the range of 0.5–1.5 t/ ha. Wheat products are integral ...
Integrated watershed management in the upper catchments of Karkheh River Basin of Iran
Integrated watershed management should be pursued to improve people’s livelihoods and the ecosystem. It can be achieved when all stakeholders agree on a joint vision and action plan. Scientists should support the process ...
