Irrigation is central solution to food and nutrition insecurity in the face of rapid population growth and recurring droughts, as agriculture remains the main livelihood for most Malawians. The Government of Malawi is investing and promoting irrigation farming in its attempt to mitigate the negative effects of climate change on agriculture and food security. The investment urge has been noticed with heavy irrigation investments made on Shire Valley Transformation Program and Program for Rural Irrigation Development that is developing over 50,000 ha irrigation infrastructure. Nevertheless, the Malawian irrigation system is still one of the most inefficient and low on investment return irrigation system in the Sub-Saharan Africa. Most Malawian farmers still irrigate by trial and error
thereby making irrigation more expensive than in other developing regions thereby lowering probability of generating a return on investment. This setback reduces investment in irrigation water. But studies by the Department of Research Services at Kasinthula have proved that use of simple soil moisture and monitoring tool can help farmer solve this problem. This policy brief presents evidence of why Chameleon Sensor Array should be scaled through PPP in order to achieve sustainable irrigation water management and adapt farmers to impact of climate change in Malawi.
