Introduction Mpumalanga Tourism and Parks Agency (MTPA) called for a report to assist and advise the MTPA Board on mining within protected environments within Mpumalanga Province. Questions arose following the application to mine in the recently proclaimed Mabola Protected Environment (MPE). This report is aimed at addressing the key questions in this regard, posed by the MTPA Board, namely: 1. Status around mining in a declared protected environment. 2. Was the declaration of the Mabola Protected Environment well founded? 3. What would be the magnitude, scale, duration and permanence of impacts on biodiversity, water yield and quality, agricultural and tourism potential of the proposed Yzermyn coal mine in the Mabola Protected Environment? 4. What may the social, political and legal consequences be, locally, regionally, nationally and internationally, of de-proclaiming the Mabola Protected Environment to allow mining to take place? The report considers each of these in turn (although the order of questions 3 and 4 are swapped). Followed by a set of recommendations. The Issues are looked at initially from a broader national perspective (although local examples are used) and then later focusing into the issues particular to the Mabola Protected Environment. Each component has had input from a team of experts with legal, mining, biodiversity, wetland, social and other expertise. It is intended that this report will provide not only advice, but assist in building capacity and developing policy for the future management of similar situations. 2. Overview - mining in a protected environment This section answers the question: What is the status around mining in a protected environment? The purposes of proclaiming an area as a Protected Area is defined within Section 17 of National Environmental Management: Protected Areas Act (NEMPAA). There are various forms of protected areas, one of which is a Protected Environment. The purpose of a protected area is to protect ecologically viable areas representative of South Africa’s biological diversity and natural landscapes, preserve
