Patterns and Drivers of Regional Crop Production in Chad
Mönster och drivkrafter inom regional jordbruksproduktion in Chad
Author
Summary, in English
In general it found that the harvested area has been increasing faster than the yield, and that a majority of the changes have happened under abrupt rather than gradual changes. By using this detailed understanding of the patterns of change, and by combining numerous kinds of relevant datasets on hydrology, demographics, international aid, market prices, conflicts, and agricultural practices, this thesis has evaluated potential factors of these changes with an extent and detail that have not been done before. This evaluation have showed that variations in hydrological conditions, market prices, and food security conditions can be linked to the variability in crop production. By looking at descriptions of livelihood conditions in agricultural areas, factors such as material and technical farm support have been linked to abrupt changes in the crop production for specific areas. Also, the differences in long term change between the administrative regions in Chad have been explained by differences in demographic factors and amount of international aid received.
These and similar results are relevant to increase the understanding of how agricultural societies evolve in Chad, and how strategies and interventions can be developed to assist local communities in their objectives. More specifically, the results can be used to evaluate the effects of certain events or policies, and to improve seasonal predictions for crop production and food availability. Beyond Chad, the results and methods developed for this thesis are relevant for application in the wider Sahel, where the agro-ecological and institutional conditions share some key characteristics.
