Investigation of the viability of selected indigenous wetland plants to support
Expanded Title:The Water Research Commission’s “light-house” flagship programmes are trans-disciplinary, multi-KSA and inter-institutional mega-projects that examines priority water issues across the innovation value chain. Amongst these programmes, the Green Village Programme (GVP) intends to reduce carbon/ecological footprints by adopting more environmentally-friendly options (‘green’ options), in realisation of the centrality and importance of healthy ecosystems. In addition the GVP promotes the Sustainable Development Goals in encouraging green and sustainable options namely; promoting sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all; building resilient infrastructure, promoting inclusive and sustainable industrialization and fostering innovation; and protecting, restoring and promoting sustainable use of terrestrial ecosystems. Thus the GVP is an important mechanism for fostering development towards a green economy. An important part of the GVP is thus to create economic opportunities for marginalised communities by addressing their basic needs such as generating green jobs without compromising the integrity of the environment and the future generations. In short, the GVP must add value and transform living standards, creating economically active communities which are integrated into the mainstream economy. This document is structured according to the general business case guidelines provided by National Treasury, which are applicable for all government departments and public entities. The business case is a detailed yet succinct document, supported by a series of Appendixes which contains the detailed research conducted in support of the business case. This is a GVP business case for creating a Typha capensis (Cape Bulrush or Cattail) (hereinafter referred to as “Typha”) value addition venture, which creates significant economic and employment opportunities. This is a quasi-Payments for Ecosystem Services (PES) initiative. Typha is an indigenous wetland plant (refer to Figures 1a & 1b) that occurs across the country (refer to Figure 1c). It acts as a pioneer species in degraded wetlands, which means that fairly dense populations of Typha occurs in various degraded wetland systems across the country. Typha is therefore an abundant and fast growing plant species, which plays an important role in the rehabilitation of degraded wetlands, especially where nutrient pollution occurs. The Working for Wetlands Programme has identified certain wetlands where this indigenous species has become an environmental problem, due to it out-competing other species. This business case therefore has the added benefit of generating a revenue stream from a species which is effectively a weed in some wetlands. In addition, German research and development initiatives (http://www.ibp.fraunhofer.de/en.html) have demonstrated the successful use of Typha as a construction material. The Fraunhofer-Institute for Building Physics IBP has developed a panel product and has used it for external and internal wall construction. The manufacturing technology for this is relatively simple.
