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 productivity (WP).
Widespread heat waves, floods, and droughts last year were a strong reminder of the threats posed by climate change. In the non-tropical dry areas where ICARDA works we are becoming accustomed to record high temperatures and increasing water scarcity year on year.
This issue of Caravan describes the new program, and some of the research innovations it will build on. The issue begins with two ‘opinion pieces’ by scientists from partner organizations in the CRP.
Wheat is the main cultivated crop in the LKRB (mainly the Dashte- Azadegan plain). Its average yield is 1500 kg/ha (Agricultural Statistics 2004).
Salt-prone land and water resources are major impediments to the optimal utilization of crop production systems in many arid and semi-arid regions of the world, including Iran (Alizadeh et al. 2004; Moghaddam and Koocheki 2004).
CGIAR Challenge Program on Water and Food - Improving livelihood resilience by integrated natural resource management in upper catchments of dry areas (pn24) and improving on-farm agricultural water productivity in the Karkheh River Basin (pn8).
This document presents the Strategic Plan of the International Center for Agricultural Research in the Dry Areas for the period from 2017 to 2026.
Research Report no. 4 of the CPWF project: Improving on-farm agricultural water productivity in the Karkheh river basin (PN8).
Non-tropical dry areas cover over 40% of the world’s land surface with a growing population of more than 2.5 billion people. These people grow 44% of the world’s food and keep half of the world’s livestock, yet one in six live in chronic poverty.
