- Description: Risk is the result of two interacting components: hazard and vulnerability. Climatic hazards are related to extrinsic factors such as drought or severe storms. Vul- nerability is the result of intrinsic factors that often arise from the socio-political- economic context. The interplay of risk and vulnerability is difficult to predict. Although computer models have been widely used to forecast climate related risk, albeit with con- siderable uncertainty, they can never capture sufficiently the vulnerability of human sys- tems to these hazards. Role-playing games can be used more realistically to simulate pos- sible outcomes of different climate change scenarios, and allow players to reflect on their significance. The authors have developed the African Catchment Game to simulate a wa- ter scarce African country. Risk can be modelled mechanistically by changing the nature of the annual rainfall input. Vulnerability can in part be modelled by changing the start- ing parameters (such as access to land and resources) and, secondly, through the unpredictable response of players to game dynamics. Players’ reflections demonstrate that through the game they become more aware of the concept of risk and the complex response of individuals and societies that determine their vulnerability to climatic hazards. This paper reflects on the potential for developing the game further as a tool for participatory learning around climate change, based on the authors’ experience of playing the game with participants from South Africa.

- Description: South Africa's National Water Act (NWA no 36 of 1998) recognizes the need for environmental protection through the ecological Reserve, defined in the Act as the quantity and quality of water required to protect aquatic ecosystems in order to secure ecologically sustainable development through the constrained use of the relevant water resource. Further more the NWA stipulates that the allocation of licenses to new water users, or the granting of increased water use to established water users, can only take place once the the Reserve for the river has been determined and approved by the Minister. This means that water users' needs (beyond those required for basic human needs) take second place behind the environment. Whether or not the inclusion of the ecological Reserve in South Africa's water legislation leads to sustainable use of South Africa's water resources depends on its successful implementation. This in turn depends on the will of both the Department of Water Affairs and Forestry (DWAF), the implementing agent, and the end water users who need to be convinced of the priority given to environmental needs. In this paper we look at the process of implementing the ecological Reserve in the Kat Valley in the Eastern Cape of South Africa as part of a stakeholder driven process of developing a water allocation plan for the catchment that prioritized participation by water users. The extent to which DWAF and the water users expedited or thwarted the process is examined in the light of national and international calls for local-level participation in water resource management processes.

- Description: The relationships between the spatial distribution of gully erosion and topographic thresholds in the form of slope angle, position and configuration, as well as land use change in the form of abandoned lands were examined in several affected catchments of the Eastern Cape Province, South Africa. Land use and permanent gullies were mapped, digitized from orthophoto maps in Arc/info 3.5.2 GIS and converted to shapefiles using ArcView 3.2 GIS. Relationships between the mapped phenomena and topographic variables were sought using a Digital Elevation Model (DEM) in Idrisi Kilimanjaro GIS. A comparison between areas with a high potential for gullying and actual gully erosion was made using the Stream Power Index (SPI) as a surrogate for critical flow shear stress. Field surveys were also conducted to assess the present condition of the gullied sites as well as to validate DEM derivations. Seventy five percent of the gullied area was noted to lie on abandoned lands. A predominance of gullying in concave bottom lands was also identified. The SPI values highlighted a distinct preferential topographic zone for gully location. A conceptual model depicting the interaction between land use and topographic parameters to induce gully erosion was developed. This should assist local authorities to develop a policy regarding management of abandoned lands.
