It is widely known that climate change and agriculture are interrelated process, both of which take place on a global scale. In effect, crop and animal farming, fisheries, forestry, with the resultant access to food and fibre in many continents and regions of the world are projected to be severely compromised by climate variability and change. Several strategies aimed at reducing climate variability induced hazards abound. These include cultural and conventional food and farming systems to climate variability and these are aimed at enhancing the adaptive capacity and mitigation. In this study, we are investigating the separate and joint effects/impacts that the use of various climate change adaptation strategies have on crop yields and on the resultant marketed values of crops. We are applying instrumental variables method on a cross-sectional survey data of two states (Osun and Oyo) of south western Nigeria to evaluate these impacts. The findings suggest that the use of climate change adaptation strategies has impacted on expected yield and on marketed crop outcomes. Policy indicative variables suggest that sustainable crop production can be achieved in the face of climate change and this can effectively create a win-win situation from the synergy between African and European agriculture.
