Participatory rangeland monitoring and management in the Kalahari, Botswana

The multi-dimensional and dynamic nature of rangeland \ndegradation makes accurate assessment a difficult challenge. Existing assessment methods rarely integrate \ndifferent components of land degradation and local communities rarely participate, or derive results that can improve the sustainability of their land management. \nSustainability indicators offer one solution to this problem. They can be used by a \nrange of stakeholders to derive multi-disciplinary information that can be used to both monitor and respond \nto environmental change. However,it is increasingly claimed \nthat existing sustainability in dicators provide few benefits to local users who, as a consequence rarely apply them. The thesis therefore starts by reviewing land \ndegradation causes and theoretical models in semi-arid \nrangelands and critically evaluates a range of degradation \nassessment methods in the semi-arid rangelands of \nBotswana. This shows that multi-source,multi-scale land degradation assessment can provide more accurate and \nreliable results than the use of any single technique \nalone. This information is used to identify potential land degradation "hotspots",and a learning process for sustainability assessment is developed and tested in three of these problem areas. The process is designed to facilitate two-way and meaningful interaction between local communities, researchers and policy-makers to monitor \nenvironmental sustainability and respond appropriately. \nApplication of the process identified a range of innovative management options that could prevent,reduce, reverse or help rangelands takeholders adapt to land degradation.Communities identified a wide range of sustainability indicators, the majority of which were \nvalidated through field-based research. Local knowledge \nwas more holistic than many published indicator lists for monitoring rangelands, encompassing vegetation,soil, \nlivestock,wild animal and socio-economic indicators.By building on local knowledge,the indicators and management options were familiar to land users who could apply them \nwithout specialist training or equipment. Indicators and \nmanagement options were integrated in a manual-style \nDecision Support System designed to help land managers easily monitor progress and adapt management to \nreach sustainability goals. These findings emphasise the value of local knowledge in rangeland monitoring and management. However, they also emphasise the need to \nintegrate this with the knowledge of researchers, and open dialogue about environmental sustainability between communities, researchers and policy-makers. \nBy combining qualitative insights from participatory research with more top-down empirical research it has been possible to produce more accurate and relevant results \nthan either approach could have achieved alone. However, the future success of this work depends to a large extent on institutional reform in Botswana, as many of the \nmanagement options are only likely to be effective under common property land tenure.
