This study applied a modified deterrence model to evaluate the effectiveness of legitimacy and ethical factors compared to deterrence measures for compliance with mesh size regulation in the Jebel Aulia Reservoir of Sudan. The ordered probit and zero-truncated negative binomial models were...

This paper examines the distribution of climate change impacts across the 16 agro-ecological zones in Africa using data from the Food and Agriculture Organization combined with economic survey data from a Global Environment Facility/World Bank project. Net revenue per hectare of cropland is...
