Abstract
The study investigated the impact of climate change on yields of leading food crops in Nigeria and assessed the transmission channels of climate shocks to welfare. Long-run causality test, Markov-switching regression and Structural Vector Autoregressive (SVAR) model were used. Long-run causality between climate change and crop yields was not rejected. A rise in temperature by 1% reduces crop yields by -0.12% in the regime of high yield while 1% increase in rainfall increases yields by 0.21% and 0.26%, respectively in high and low yield period. Shocks to welfare is traceable to climate change via crop yields and food prices effect.
期刊介绍:
Understanding the development of the food system requires a system view that captures the complexity of the system and its many interrelationships with its economic, social and natural environments. The Journal accepts and offers papers within this broad range of issues focussing on the management, policy, marketing, consumer aspects, transparency, e-commerce, institutional or regional development, information and communication systems, ressource economics, production economics, chain management, network economics, and similar aspects. Papers may focus on modeling, empirical research or theoretical analyis. This broad range of publication opportunities asks authors to follow clear lines of arguments and to present arguments in a convincing way that avoids unnecessary complexities of model formulations if not relevant for the support of arguments. The publication of scientific articles is complemented by a number of sections that provide room for publications with a more specific focus: ''Case studies'': A section on case studies of the ''Harvard Type'' allows the publication of studies that might build on established scientific methodology but demonstrate its use in ceratin decision environments. Case studies might be complemented by ''teaching cases'' that are kept on a database outside the journal but accessible to readers on approval by authors. ''Research Forum'': It allows to discuss newly emerging research challenges or to contribute to ongoing scientific discussions on research problems. In addition, authors might initiate a discussion on issues brought up by articles published in the journal. ''Research Notes'': It provides room for specific shorter scientific contributions with a narrow scope.
