During the decade a 'new rangeland science' has emerged. One of the tenets of this science is that pastoralists should not adhere to a single conservative stocking rate but rather, adopt an opportunistic strategy where numbers will fluctuate widely in response to good and bad seasons. It is furth...

This articles included in this special section focus on the ecological and economic interactions of woodland use in Western Zimbabwe. One of the aims was to investigate the use of modeling to achieve integration among disciplines. The integrated model draws on the models in the different papers c...


Campbell, Bruce M.Costanza, R.Belt, M. van den[Special section: land use options in dry tropical woodland ecosystems in Zimbabwe: introduction, overview and synthesis]Special section: land use options in dry tropical woodland ecosystems in Zimbabwe: introduction, overview and synthesis

This paper use a conceptual box-and-arrow model for understanding woodland use in Zimbabwe in the context of the complex ecological-social-economic system of which it is part. Central themes within the model are: the policy framework; local institutions; land pressures; rural-urban relationships;...

Assessing the performance of management is central to natural resource management, in terms of improving the efficiency of interventions in an adaptive-learning cycle. This is not simple, given that such systems generally have multiple scales of interaction and response; high frequency of non-lin...

We examined the changes in forest status and people’s livelihoods through building future scenarios for Chilimo Forest in Central Ethiopia where participatory forest management (PFM) is being implemented. Participatory methods were employed to collect data, and a dynamic modeling technique was ap...

To meet the challenges of poverty and environmental sustainability, a different kind of research will be needed. This research will need to embrace the complexity of these systems by redirecting the objectives of research toward enhancing adaptive capacity, by incorporating more participatory app...

This paper examines the history of forest management and conservation in the Congo Basin. It identifies some of the reasons for the limited success in applying ecosystem approaches to forest management. The lack of long-term consistent policies and programmes and the relative weakness of forest s...
