INTRODUCTION The Harry Gwala District Municipality (HGDM), in partnership with the KwaZulu-Natal (KZN) Department of Economic Development, Tourism and Environmental Affairs (EDTEA), embarked on a process to develop an Environmental Management Framework (EMF) for the district. Nemai Consulting was appointed to prepare the HGDM EMF. An EMF includes a framework of spatially represented information connected to significant environmental (i.e. ecological, social and economic) parameters, such as ecology, hydrology, infrastructure and services. A key function of an EMF is to proactively identify areas of potential conflict between development proposals and critical/sensitive environments. This report represents the Status Quo assessment (Volume 1) of the HGDM EMF process and serves to understand the current state of the environment and to identify the issues, opportunities and constraints in Harry Gwala. The outcomes of the status quo will provide the foundation upon which the remainder of the EMF deliverables will be built. HGDM, formerly known as the Sisonke District Municipality, is a Category C Municipality situated in the south of KZN. The district covers an area of 10 547km². The district borders with Umgungundlovu DM to the north-east, Alfred Nzo DM to the south and south-west, Ugu DM to the south-east and Lesotho to the north-west. The district also includes the southernmost part of the uKhahlamba Drakensberg Park World Heritage Site (UDPWHS). In order to address the triggers for sustainable development in the HGDM and the priority environmental opportunities and constraints, some of the key objectives of the EMF include facilitating environmental decision-making and providing strategic guidance on environmental, economic and social issues in the District. The catalysts for initiating the HGDM EMF fall within the following categories: 1. Significant environmental factors; 2. Development pressures; 3. Environmental threats; and 4. Resource management issues. March 2018 i Harry Gwala District Municipality EMF: Status Quo Report (Draft) B. EMF DEVELOPMENT APPROACH The EMF development approach, which is outlined in the figure to follow, is consistent with the requirements stipulated in the National Environmental Management Act (Act No. 107 of 1998) and the EMF Regulations (GN No. R547 of 18 June 2010). C. ENVIRONMENTAL PROFILE The Environmental Profile describes the current state of the environment which was ascertained through inter alia baseline evaluations and descriptions, specialist studies (as required), desktop assessments, existing data assimilation and field verification and assessment (as required) March 2018 ii Harry Gwala District Municipality EMF: Status Quo Report (Draft) The environment in the District is explained in terms of the following features and attributes that serve as the building blocks for the environment. Where possible, these elements have been spatially represented in the EMF Geographic Information System (GIS). Environmental Features Assessed during the EMF Status Quo Phase . Climate . Urban Edges . Geology . Demographic Profile . Geohydrology . Economic Profile . Terrain Morphology . Tourism . Surface Water . Access to Services . Terrestrial Ecology . Electricity Supply . Agricultural Potential . Transportation . Soils . Solid Waste Management . Air . Health Facilities . Land Use & Land Cover . Disaster Management . Spatial Planning . Traditional Leadership . Strategic Integrated Projects . Land Claims . Historical & Cultural Resources D. ENVIRONMENTAL MANAGEMENT PRIORITIES This first phase of the EMF development process culminates in the identification of environmental management priorities through an understanding of the environmental issues, constraints and opportunities within the District. E. TRANSITION FROM STATUS QUO TO DESIRED STATE With the foundation of the EMF set through the Status Quo Phase, the next step is to determine a realistic desired state for the environment in HGDM. Establishing the desired state includes providing the environmental management context for the management zones and related requirements for the various environmental features for the Srategic Environmental Management Plan (SEMP). It will also focus on addessing the imperatives that lead to the instigation of the EMF development process. The approach to defining a desired state in Harry Gwala is based on evaluating and integrating environmental management priorities, environmental sensitivity, development opportunities, development pressures and trends, as well as public aspirations.
