In the Ankole pastoral production system animals are grazed on pasture all year round. The cattle are not supplemented with conserved pasture or commercial feed except minerals. The large number of factors that influence production makes it impractical and expensive to use field trials to explore...

In semi-arid south-western Niger, climatic variability, low productivity, poverty and institutional constraints limit the scope of agricultural production to meet the rising needs of the growing human population. The integration of crop and livestock production activities has long been seen as th...

This paper describes an integrated framework for assessing the sustainability og managed forests. The framework builds on Geographic Information Systems (GIS) and Multiple Criteria Decision Making (MCDM). Sustainability of forests is assessed in terms of Criteria and Indicators (C & I) as propors...

This chapter attempts to systematically examine some of the main analytical arguments and empirical evidence regarding the impact of technological progress in agriculture on deforestation. Three factors have been highlighted that are important in determining deforestation outcomes: (1) the type o...

This paper presents a methodology employed in reconciling demands of households, private sector, and government on miombo woodlands of Southern Africa. A Weighted Goal Programming approach is presented for planning management and use of the woodlands as well as a framework for policy analysis. Th...

Although we approve of their goals, we have significant concerns about both the technical accuracy and local understanding revealed in Sandker et al. (2007). One value of modeling, as the authors indicate, is to help stimulate debate about important, complex issues. Debate is enhanced because a w...

This paper presents different models designed to operationalize the principle of forest sustainability. Concepts such as resource or environmental utilization space, carrying capacity and critical thresholds are defined. The paper also describes an application of the qualitative and quantitative ...

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...
