    The rapid urban development in the Hurghada area since the 1980s has dramatically enhanced the potential impact of human activities. To inventory and monitor this urban development effectively, remote sensing provides a viable source of data from which updated land cover information can be extracted efficiently and cheaply.

    Dense multi-temporal stacks of Landsat imagery have most commonly been exploited to identify land cover and land use changes (LCLUC) based on detection of abrupt changes in continuous value spectral indices. In this study, a discrete classification approach to LCLUC identification based on stable training sites is tested on a nine-date, 4-year Landsat-7 ETM + time sequence for a study area in Ghana that is prone to cloud cover.

    Combining spatially explicit land cover data from remote-sensing and faunal data from field observations is increasingly applied for landscape-scale habitat and biodiversity assessments, but without modelling changes quantitatively over time. In a novel approach, we used a long-term time series including historical map data to predict the influence of one century of tropical forest change on keystone species or indicator groups in the Kakamega–Nandi forests, western Kenya.

    Africa

    In the savanna rangelands of southern Africa, the debate about land reform tends to be about the redistribution of formerly freehold ranches and fencing-off the rangeland commons into ranches for better-off African farmers. The position of those who favour privatisation has been strengthened by the belief that the only environmentally sound way to manage the range is to subdivide it into private ranches because traditional open-range pastoralism is environmentally destructive. This point of view is at variance with an ever-increasing body of research.

    In this paper the use of fenced grazing camps to manage the rangeland commons is challenged. A historical perspective is presented on fencing and rotational grazing in South Africa. Two case studies in KwaZulu-Natal and the Northern Cape illustrate the factors that influence the management of rangelands under communal land tenure without the use of fences. It is argued that herding is preferred over fencing.

    The paper critiques Vetter's (in this issue) assertion that commercialisation of smallholder agriculture holds dangers for sustainable rangeland management. The paper argues that a range of policy options are required, including commercialisation and subsistence farming, large-scale and smallholder farming, a range of land tenure options, rural and peri-urban farming, and part-time farming. The case of municipal commonage land is useful to show the effectiveness of a flexible range of policy options regarding land ownership, farming scale and the social nature of farming.

    In many developing countries, land ownership remains a subject of contention. In South Africa, notwithstanding the strides that have been made to foster equitable land ownership, land reform policies have been unsuccessful in delivering land to the poor majority. Due to the nature of agriculture as a source of food production and national security, and the lack of farming skills and related competencies’ equilibrium, programmes intended to deliver land to black people have been inadequate in their reach.

    Tanzania

    This article shows how wildlife and marine conservation in Tanzania lead to forms of ‘green’ or ‘blue grabbing’. Dispossession of local people's land and resources has been gradual and piecemeal in some cases, while it involved violence in other cases. It does not primarily take the usual form of privatization of land. The spaces involved are still formally state or village land.

    Against the backdrop of post-Apartheid neoliberal reform, South African landowners have gained the option to acquire full ownership over wild animals on their land. Corresponding with this, approximately one sixth of South Africa's total land has been ‘game-fenced’ and converted for wildlife-based production (i.e. hunting, ecotourism, live trade and venison production). This article analyzes the institutional process in which authority concerning access to wildlife is being restructured, and argues that the unfolding property regime leads to an intensified form of green grabbing.

    Using an analysis of aerial photographs from 1942, 1985 and 2004 we assessed the impact of changing land tenure and land-use regimes on the cover of thicket vegetation on the Grahamstown commonage. Land-use impacts were examined by comparing plant species composition within three vegetation types between sites incorporated into commonage for different lengths of time and sites outside the commonage. Results showed that thicket cover increased by 87% between 1942 and 1985 but declined by 11% between 1985 and 2004.
