Sustained Development of Land Resources : A Policy Model for Sudan

The paper develops a model that shares common features with the computable general equilibrium (CGE) models. It is used to address two questions. First, what are the future prospects of a green gross domestic product (GDP), should we be concerned for resource degradation or not, and to what extent, and under which conditions? Secondly, which policies are more effective than the others? Different model closures are simulated relating to different specifications of exogenous variables. Furthermore, alternative policies are treated: human capital, price incentives, property rights and poverty reduction. In the African context, we show that while the prospects of environment-friendly economic development, i.e. a rising green GDP, are weak in the medium-run, yet under certain structural conditions there is a range of effective policies that resolve the conflict between economic growth and resource degradation, and contribute positively to a rising green GDP
