PARI Policy Brief No. 6: Improving Employment Prospects for Africa’s Rural Youth
Given that the agriculture sector remains the most important economic sector in the region, policies that support its development and increase the human capacities of rural youth can significantly improve employment opportunities and quality.
Physical robustness of canopy temperature models for crop heat stress simulation
Despite widespread application in studying climate change impacts, most crop models ignore complex interactions among air temperature, crop and soil water status, CO2concentration and atmospheric conditions that influence crop canopy…

Enhancing resilience to climate shocks through farmer innovation: evidence from northern Ghana
Using data from rural Ghana, this paper aims to add new empirical insights into the impact of farmer innovation by focusing on resilience to climate shocks.
PARI Policy Brief No. 5: Smallholder agricultural mechanization in Africa
This policy brief analyses which governance challenges must be addressed to make mechanization economically, socially and environmentally sustainable.
Change in crop management strategies could double the maize yield in Africa
The crop model SIMPLACE was used in this study and it was tested against FAO statistics to evaluate the model performance under the current management conditions with traditional cultivars and average nitrogen application rates.
The uncertainty of crop yield projections is reduced by improved temperature response functions
The inter-comparison of 29 wheat models showed that uncertainty in simulated wheat yield from different models increases with rising temperature, which provides the background and forms the basis for our current study.
Weather impacts on crop yields – searching for simple answers to a complex problem
The article discusses the importance of information on the extent to which crop yields are affected by specific extreme weather events to guide extension services and policy making or support crop breeding efforts.
