Presents a cattle herd simulation model which is time dynamic, stochastic, non-optimizing & integer and permits the evaluation of herd performance under alternative production regimes; discusses the analytical background to the biological relationships represented in the model, describes detailed...
Describes a dynamic & stochastic simulation model, specifying its driving variables & validating it for production conditions in a study area in Botswana. Compares the simulated performance of Tswana & Simmental x Tswana cattle, analysing economic trade-offs between milk & meat production under v...
Bean (Phaseolus vulgaris L.) productivity is much constrained by water deficits in many production areas in eastern and southern Africa. The DSSAT 3 Drybean model was used to analyze the effects of water deficits on bean using genetic coefficients of four cultivars including an early, determinate...
The severe tensions between conservation and development are illustrated by events in Malinau District (Kalimantan, Indonesia). Conservationists decry proposed plans for logging and conversion of pristine tropical forest to oil palm (Elaeis guineensis). Although the local government is willing to...
Co-View is a tool to help facilitators of natural resource management and stakeholders to articulate and explore a shared vision of the future and to develop strategies to achieve it. One promising approach for coping with change is by generating a shared vision of the future through facilitated ...
Sustainable development strategy urges that forest management be carried out in a participatory way. The importance of communities’ participation has been written into Indonesian Law no. 41 on Forestry (1999). However, how this law can be implemented in areas already allocated to a concession hol...
Integrated conservation and development projects (ICDPs) have had limited success in addressing the often conflicting objectives of conservation and development. We developed a model with local participants to explore the trade-offs between conservation and development in southeastern Cameroon, w...
