Congruence between plant and insect diversity is considered possibly useful in conservation planning, as the better known plants could be surrogates for the lesser known insects. There has been little quantification of congruence across space, especially in biodiversity rich areas. We compare here species richness, and turnover relationships between plants and flower-visiting insects across space (0.5–80 km) in natural areas of a biodiversity hotspot, the Greater Cape Floristic Region, South Africa. A total of 22,352 anthophile individuals in 198 species and 348 plant species were sampled. A comparison between the plants and anthophiles suggest significant concordance between the two assemblages. However, turnover was weaker in plants than in anthophiles. Plant turnover decreased with greater geographical distance between plot pairs. In contrast, insect turnover remained high with increasing geographical distance between plot pairs. These findings suggest that while patterns of plant diversity and distribution shape flower-visiting insect assemblages, they are not reliable surrogates. The conservation significance of these results is that specialist mutualisms are at greatest risk, and that set-asides on farms would help improve the functional connectivity leading to the maintenance of the full range of mutualisms.

Cultivation has been the primary driver of habitat transformation in South Africa. This paper explores the effectiveness of agricultural and, latterly, Environmental Impact Assessment (EIA) authorisation procedures in stemming biodiversity loss resulting from cultivation in the lowlands of the Cape Floristic Region, a global biodiversity hotspot. Owing to an activity-based focus, agri-environmental regulation has been largely unable to mitigate the cumulative effects of large-scale land clearance in threatened ecosystems. Case studies in the Sandveld and Slanghoek districts are used to argue that revised EIA regulations published in 2006 partly perpetuate the structural shortcomings of activity-based EIA. An ecosystem-based strategy for agri-environmental screening in biodiversity hotspots is introduced, drawing on conservation plans, the agricultural LandCare programme and the provision for Environmental Management Frameworks (EMF) in the 2006 EIA regulations. "Agri-EMFs", as a collaborative initiative that involves government, agricultural and non-governmental representatives, may present an effective alternative to the inefficiencies of project-level EIA.

This paper reports about a study comparing the performance of different sanitation systems delivered by Ethekwini Municipality in South Africa. The following sanitation systems have been studied: pit latrines, VIPs, urine diversion toilet, community ablution block and the conventional sewer borne flush toilet. The evaluation has been based on a 2-step approach. A rapid assessment capturing the overall situation whether the case study is performing successfully or not, followed by a more detailed evaluation focusing on those aspects where the rapid assessment could not provide sufficient results. The paper results in several lessons learned and recommendations and shows how Ethekwini has incorporated them.
