Overstrand Municipality Proposed development to address food security and protect biodiversity Research-driven Seek Discern Use Environmental and Sustainability Studies Experimental Farm Hemel and Aarde Valley, Hermanus, Western Cape, South Africa Hi my name is Qarbon. I am a Second Life Avatar representing the Qarbon Qampus Virtual World. Today we will be doing a real world assessment for a development. My Role is that of the Co-ordinator of the Environmental and Sustainability Studies at the University of the Western Cape and I am looking to build an experimental facility to assess new foods we can grow in the Western Cape given the anticipated impacts of climate change.

Description of the Experimental Farm Qarbon Campus Experimental Farm A radical new way of farming! What is the Qarbon Campus Experimental Farm and why is it different?.

Qarbon Campus Experimental Farm Where will it be located! A potential property for the location of the Qarbon Campus Experimental Farm has been identified in the Hemel-en-Aarde Valley. This valley is well known for its alternative life style communities which exists in total contradiction to the valley’s exclusive Wine Estates and the South African Rivera town of Hermanus just over the seaward-side mountians..

I will supply a composite picture to insert here…

Summary of Overberg Integrated Development Plan IDP Put text here Conservation of the Overstrand Overstrand Municipality Profile Description Overstrand Municipality is a local municipality located within the Overberg District Municipality, in the Western Cape province of South Africa. Its unique offerings of the ultimate experience in land-based whale watching and shark cage diving, pristine Blue Flag beaches, excellent wine industry and top-class restaurants and accommodation make it an attractive tourist destination with a variety of activities. General statistics Area: 1,708 km 2 Total Population 2011: Population density: 47/km 2

Experimental Farm site assessment Overberg District Conservation Plan Assessment Assessment location and Conservation Plan Assessment location The map to the left shows the assessment area which was run for the identified potential location of the Qarbon Campus Experimental Farm in the Hemel –en-Aarde Valley Assessment results The assessment report is a compilation of data of various spatial biodiversity data sets and planning production. These are: 1. National terrestrial or aquatic spatial data sets and protected area boundaries and 2. The most relevant Biodiversity Conservation Plan BCP for the municipality in which the assessment is located. in the case the the most relevant SCB is the Overberg District Conservation Plan.

National Terrestrial data sets Overberg District Conservation Plan Assessment Ecosystems, forests and soils Threatened Ecosystems Section of the report lists two national threatened ecosystems which occur with the assessment area. Although this information is extracted from the original extents of these ecosystems both the SCP results discussed below and examination of imagery confirm that natural vegetation may well exists within the area of the assessment. If this is the case it is critically endangered CR. The ecosystems in question are: 1. Elim Ferricrete Fynbos (FFf 1) 2. Overberg Sandstone Fynbos FFs 12 Note the results for the National vegetation types section confirms that the only vegetation types (ecosystems) which may occur are these two CR ecosystems. Soils The soil classes encountered (section 1.1.4) are probably associated with the two ecosystems. Further investigation into their properties revealed that 1. Association of Classes 7 and14: Undifferentiated texture contrast soils may have favourable physical properties, somewhat high natural fertility; relative wetness favourable in dry areas but can get water logged. 2. Non soil land classes has limit value for agriculture. Indigenous Forest Patches There were no indigenous forest patches (section 1.1.3)

National Aquatic data sets and PAs Overberg District Conservation Plan Assessment Rivers, wetlands and protected areas National Fresh Water Priority Areas (NFEPA) Wetlands Seven wetlands occur in the analysis area (section 2.1.1), five of these are artificial with condition Z3 where the percentage natural land cover <25% and two natural with condition Z1 classed as artificial by Surveys and Mapping. All these wetlands have the lowest FEPA rank of 6. Rivers Units Sub-quaternary catchments The analysis area intersected a single unit of the Onrus river (section 1.2.2) with a condition of C moderately modified. The analysis area was only located in this river units sub-quaternary catchment both have a NFEPA status of Fish Sanctuary. NFEPA fish sanctuaries are important areas for the support of indigenous fish species. Protected Areas (NBA 20011) The analysis area intersected a formal protected area Fernkloof Local Nature Reserve (Section 1.3) It should be redrawn to avoid this intersection. Note: The analysis area was not located in one of the focus areas for Protected Area.

Critical Biodiversity Areas Map In the Overberg District Conservation Plan a lookup layer is provided which divides the area of the plan into units each of which gives biodiversity feature information responsible for the classification of the unit’s CBA map category CBA, ESA or PA. The analysis area intersected 63 such units (section 2). In the report each unit is listed separately rather than in a table due to the amount and complexity of information it contains. Critically Endangered ecosystems (CBAs) Most of the analysis area intersected with lookup up layer units which were classified as Critical Biodiversity Areas 33 on natural or 16 degraded land 49 units in total. The biodiversity features responsible for this classification indicated potential occurrence of both endangered species and national threatened ecosystems. These units corresponds with the two critically endangered ecosystems which were listed above. Ecological Support Areas (ESAs) The analysis area intersected six CBA map lookup layer units which were classed as ESA or important for maintaining aquatic processes and may be transformed from natural e.g. farmland. Protected Areas (PAs) The analysis area intersected seven CBA map lookup layer units which were classed as Protected Area and probably corresponds with the Fernkloof intersection mentioned above although the SCP does not include the PA name.
