Abstract
Most of the existing studies on climate change adaptation are descriptive or explanatory, and focused on the socio-economic determinants of the farmers’ perception and adaptation. We design a pilot theory-based Randomized Controlled Trial (RCT) to test the impact of providing smallholder farmers with weather-related information through mobile phone SMS. Our outcome variables include labor, yield and farm income.

Experimental Design
Experimental Design
The proposed research is a pilot. Our experiment involves 6 villages selected with the support of agricultural extension officers. To ensure this, the agricultural extension officers will be associated at this stage of the study. Following the RCT design, 3 villages are randomly assigned to the treatment group (treatment villages) and the other 3 to the control group (control villages). Randomization is conducted through a public lottery. After a listing, about 50 eligible maize producers are randomly selected in each village. At the farmers-level, eligibility criteria include: a) farmers should be maize producers, b) farmers should plan to produce maize during the rainy season of 2018/2019, c) farmers should own a mobile phone, including valid and functional line number, and d) farmers should have the ability to operate (i.e. read SMS) their mobile phone. Farmers in treatment villages receive weather forecasts information. Farmers in control villages receive no intervention.
