The Role of Climate Change Adaptation in Enhancing Agricultural Yields : Evidence from Non-Randomized Experiments in Africa

I examine the effects of climate change adaptation on agricultural productivity using a unique dataset from a non-randomized experiment involving 1,811 adapted and 3,280 non-adapted farm households across four African countries. By employing instrumental variables and simultaneous equations regression models, I find that implementing adaptation strategies significantly increases crop yields by 281.1 kilograms per hectare (23.3%). Furthermore, my analysis uncovers that the impacts vary in magnitude depending on the specific adaptation measures, crop varieties, and countries involved. Ultimately, the study highlights that farmers' capacity to adapt is primarily driven by their access to information sources and working capital. Lastly, additional climatic factors beyond rainfall and temperature play a crucial role in crop development
