1 Phillipi Horticultural Area (PHA) Human impact on the environment Gr

2 Conditions of use of this overview of the PHA ppt presentation, articles and worksheets. This presentation is intended to introduce you, the educator, to the complexities of the PHA and to equip you to potentially use this local case study to give students a hands-on overview of this section of the syllabus, as it is topical, controversial and relevant. It is a compilation of slides extracted from talks given by Nazeer Sonday (spokesperson for the farmers and other organisations aiming to preserve the PHA) and a professional City of Cape Town planner and conservationist to a school’s learners, as well as some comments and discussions held amongst learners at the school after the presentations. The material presented is NOT to be used as such for other presentations please, as it is not original. Newspaper articles clipped from the Cape Times have been scanned and possible aspects which can be investigated accompany this overview. The worksheets and accompanying suggestions for approaching this topic are original and may be used for educational purposes at your school. Please consult the City of Cape Town’s website for further elucidation of aspects and policies mentioned in the presentation.

7 How the PHA has shrunk over time.

8 Land ownership in PHA Almost entirely privately owned land Non-horticultural land either wetland, dune, or biodiversity. Also illegal & non- conforming uses

9 Agriculture areas farmed in last 15 years

10 Farmed and non-farmed areas in the Northern PHA Summer: January 2007 Highlands Estate Strandfontein Road Ottery Shopping Centre Olieboom Road Varkensvlei Road Boundary Road Ottery Road

11 How water and farming challenges differ from season to season (black areas are water bodies).

12 Farmed and non-farmed areas in the Northern PHA Spring: September 2007 Highlands Estate Strandfontein Road Ottery Shopping Centre Olieboom Road Varkensvlei Road Boundary Road Ottery Road

13 Cape Flats Aquifer 2km

14 Water Security Role: Cape Flats aquifer Yield: ±18 million m³/annum. Aquifer transmissivity greatest in south-east of PHA Aquifer requires testing as a potable source Aquifer impacted negatively by horticulture but toxin levels ‘acceptable’. UNEPA study in 2006 concluded Cape Flats Aquifer can possibly supply TWO THIRDS of Cape Town’s drinking water supply. PHA farmers tap into aquifer for all year production. Cape Flats Aquifer: Extent, Depth, Capacity & Quality

15 High Water Requirement Curve Actual Water Requirement Curve Low Water Requirement Curve with WC/WDM 4. Cape Flats Aquifer Present & Future: Predicted demand & identified supply-side interventions

16 Surface water in the PHA Generally low-lying area, due mainly to sand-mining (agreement) down to 1m above water table. Numerous large perennial wetlands & many seasonal wetlands

17 Role of the PHA currently in the City Metropolitan area Food security. Water security. Economic: - Employment (farm labourers, packaging, sorting, selling). - Cut flowers. Mining: – Building sand supply. – High quality silica deposits (for glass manufacturing).

18 Food insecurity in Africa Source: AFSUN_ African Urban Food Security Network_ Battersby

19 Food security in the Western Cape Western Cape is a water scarce region: (hot dry summers & semi-desert hinterland) Mediterranean climate not conducive to domestic vegetable gardening. Western Cape identified as a climate change ‘at risk’ area. Food security is about both production and access 80% of population in CT’s poor households estimated to have food insecurity.

20 PHA’s Food Security Role Philippi Horticultural Area has access to free water from the Cape Flats Aquifer. Very close to markets (most importantly for poor households) Produces over 50 different crops & 50% of City’s fresh vegetables. Produces tonnes /year at value R150m /year ‘at farm gate’ Productivity at R90 000/ha - for viticulture it is R18 000/ha Can produce 2,5x (5x in South –West ) crops p.a. due to cool sea breezes Close to two WWTW & potentially more water sources Contributes to nutritional needs of 2 to employees (2.5kg / day) Transport cost break-point: Refrigeration required beyond 120km Unique productive green lung. Agricultural land redistribution potential. Massive opportunity for production & employment increases (c.300%) Agri-processing and research opportunities: (UWC’s Elsenburg?)

21 Mining Building sand: Deposits in Cape Town area will last for 20 years PHA the principal supplier, but remaining deposits limited to south-east area Mining permitted down to not lower than general surface level of surrounding area Glass sand: Silica sand underlies entire PHA, but only accessible near surface in centre No comparable deposits anywhere in SA Major deposit -15m deep & 315mill tons Land surface rights: Subject to Mineral & Petroleum Resources Development Act

22 Stakeholders in the PHA City of Cape Town (Mayor Patricia de Lille) and urban developers: 2 sites being contested- Rapicorp and MSP for rezoning. Phillipi Farmers and civic associations: spokesperson Nazeer Sonday. Communities in the Western Cape who are supplied with fresh produce from the PHA.

23 Urban edge Urban edge – ineffective monitoring causing problems. Illegal establishment of businesses in the urban edge over time. Rezoning of land in the urban edge is being considered from agricultural to mixed zoning, due to the changes that have been allowed by authorities through lack of monitoring in the urban edge.

24 Issues being contested by stakeholders Proposed moving of the urban edge (making the PHA smaller)- rezoning from horticulture to mixed. The best farming land is in the south of the PHA. This land is currently owned by developers and so it is not being farmed. Farmers want this land. Farmers in the north experience difficulties with farming (dry, limited water access, poor soil quality). They are keen to sell their land to developers and buy farming land in the south of the PHA.

25 Political vs. professional decision- making for areas like the PHA. Professional town planners and conservationists have a 100 year plan in place for the PHA and other areas in the City Metropolitan area. Each time a political party wins an election (potentially every few years), there is pressure on the party to deliver on promises made in elections or to meet demands by communities in order to ensure continued support of the party. Lack of funding can prevent timeous provision of infrastructure and serviced sites to communities by municipalities (which are run by political parties). By allowing developers to build housing developments with the intrinsic infrastructure needed, some of the pressure on local municipalities to provide serviced sites and infrastructure is alleviated, so developers have leverage over politicians who benefit from the good press associated with infrastructure delivery.
