    Although advances in remote sensing have enhanced mapping and monitoring of irrigated areas, producing accurate cropping information through satellite image classification remains elusive due to the complexity of landscapes, changes in reflectance of different land-covers, the remote sensing data selected, and image processing methods used, among others. This study extracted agricultural fields in the former homelands of Venda and Gazankulu in Limpopo Province, South Africa.

    It is well known that land-use changes influence the hydrological cycle and that those changes in the hydrological cycle influence land use. The sophisticated spatial dynamic planning tools that have been developed in the last decades to support policy makers in the decision making process do not take into account the mutual feedbacks between land use and hydrology.

    The UN recognition of a human right to water for drinking, personal and other domestic uses and sanitation in 2010 was a political breakthrough in states’ commitments to adopt a human rights framework in carrying out part of their mandate. This chapter explores other domains of freshwater governance in which human rights frameworks provide a robust and widely accepted set of normative values to such governance. The basis is General Comment No.

    Limited historic vegetation data (prior to the 1980s) are available for Namibia. Finding such historic data at Haribes prompted a follow-up survey of the vegetation. We present a classification of the recent data in this paper as a first step towards comparing the two data sets. Six new associations (three with two subassociations each) are formally described. The landscape at Haribes is dominated by a pan with surrounding hummock dunes.

    The Incomati basin encompasses parts of South Africa, Swaziland and Mozambique, and is a water stressed basin. Equitable allocation of water is crucial to sustain livelihoods and agro-ecosystems, and to sustain international agreements. As compliance monitoring of water distribution by flow meters is laborious, expensive and only partially feasible, a novel approach has been developed to estimate water withdrawals using satellite measurements. Direct withdrawals include pumping from rivers, impoundments and groundwater, for irrigation and other human uses.

    This paper addresses the problem of extending biodiversity conservation onto thecommunal lands of the Dwesa-Cwebe conservation area in the Eastern Cape, SouthAfrica, by investigating the conditions that must be fulfilled for any success to beregistered. These conditions were derived based on a qualitative survey conducted in theNqabara Administrative Area. The study developed a conceptual framework to unravelthe complex nature of the whole community conservation initiative.

    The historical legacy in South Africa of apartheid and the resulting discriminatory policies and power imbalances are critical to understanding how water is managed and allocated, and how people participate in designated water governance structures. The progressive post-apartheid National Water Act (NWA) is the principal legal instrument related to water governance which has broadly embraced the principles of Integrated Water Resources Management (IWRM).

    In an economic analysis the present use of the most important national park in South Africa, (Kruger National Park) is compared with the use of the same land for agricultural purposes. The present use of the Kruger National Park creates substantially more net social benefits to society than agricultural use. The question remains whether these benefits are equitably distributed at various levels of the South African society.
