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 ...

Participatory approaches to development in general and natural resource management in particular are now a widely accepted management strategy. Multi-agent system (MAS), a computer-based tool, offers a promising approach for multi-stakeholder management systems such as the case involving communit...

The high species diversity of mixed tropical forests hinders the development of forest dynamic models. A solution commonly adopted is to cluster species in groups. There are various methods for grouping species that can be linked to three strategies (i) the ecological subjective strategy, (ii) th...

Certain landscapes in the Sahel and elsewhere consist of a 'checkerboard' arrangement of vegetated and non-vegetated areas in which there may be several spectrally distinct vegetation and bare ground components. When individual components form large spatially coherent patches, and the vertical di...

Groundwater is an important resource for multiple uses in South Africa. Hence, setting limits to its sustainable abstraction while assuring basic human needs is required. Due to prevalent data scarcity related to groundwater replenishment, which is the traditional basis for estimating groundwater...

Climate change will cause shifts in areas suitable for cultivation of a wide range of crops. We used current and projected future climate data for ~2055, and the Ecocrop model to predict the impact of climate change on areas suitable for all crops listed in Table 1 of the International Treaty on ...
