In 2008, the Government of Zambia reformed its mining tax regime for large-scale copper mines through a unilateral legislative change. The country went from having one of the lowest average effective tax rates and government take to be above the average. We focus on a particularly controversial...

Botswana has serious environmental problems which, if not addressed, will undermine the attainment of sustainable economic development. This study attempts to determine what aid flows have actually been doing with regard to the environment in Botswana. The results show that although both the...

We analyse policy makers' incentives to fight corruption under different institutional qualities. We find that 'public officials', even when non-corrupt, significantly distort anti-corruption institutions by choosing a lower detection probability when this probability applies to their own...

The present study develops a reliability assessment method of wind resource using optimum reservoir target power operations that maximizes the firm generation of integrated wind and hydro power. A combined water resources model for a system of reservoirs that implements a priority based linear...

Botswana's welfare state is both a parsimonious laggard in comparison with some other middle-income countries in Africa (such as Mauritius and South Africa) and extensive (in comparison with its low-income neighbours to the north and east). Coverage is broad but cash transfers are modest. This...

Traditional 'delta-change' approach of scenario generation for climate change impact assessment to water resources strongly depends on the selected base-case observed historical climate conditions that the climate shocks are to be super-imposed. This method disregards the combined effect of...

Water and sanitation sectors have been the 'natural' subjects of aid for several decades. However, these sectors also were among those most affected by changes in aid approaches and tools. The aim of this paper is to capture some of the complexity in assessing impact and effectiveness of aid in...

Projections of regional changes in seasonal surface-air temperature and precipitation for the eastern and western Zambezi River Basin regions are presented. These projections are cast in a probabilistic context based on a numerical hybridization technique of the MIT Integrated Global System...

Ethiopia is powering ahead with an ambitious energy development strategy, highly reliant on abundant hydropower potential. A changing climate, including uncertain water supply, however, may pose a salient challenge to meeting expected targets. Bridging the modeling gaps between climate, energy,...

Climate change is a phenomenon leading to randomly distributed disasters around the globe. Due to massive economic and technical asymmetry between the advanced North and the developing South efficient climate and industrial policy is particular difficult. Globally efficient policy would need to...
