Agricultural activities have dramatically altered our planet's land surface. To understand the extent and spatial distribution of these changes, we have developed a new global data set of croplands and pastures circa 2000 by combining agricultural inventory data and satellite-derived land cover data. The agricultural inventory data, with much greater spatial detail than previously available, is used to train a land cover classification data set obtained by merging two different satellite-derived products (Boston University's MODIS-derived land cover product and the GLC2000 data set).

Global food demand is increasing rapidly, as are the environmental impacts of agricultural expansion. Here, we project global demand for crop production in 2050 and evaluate the environmental impacts of alternative ways that this demand might be met. We find that per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960. This relationship forecasts a 100–110% increase in global crop demand from 2005 to 2050.

Global biomass demand is expected to roughly double between 2005 and 2050. Current studies suggest that agricultural intensification through optimally managed crops on today's cropland alone is insufficient to satisfy future demand. In practice though, improving crop growth management through better technology and knowledge almost inevitably goes along with (1) improving farm management with increased cropping intensity and more annual harvests where feasible and (2) an economically more efficient spatial allocation of crops which maximizes farmers' profit.

Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably.

The conflict between the Ife and Modakeke appears to be a protracted and seemingly intractable intra-ethnic conflict that has continued to pit two groups of the same ethnic background against one another. This study, therefore examined the role of traditional institution in managing Ife-Modakeke conflict. The study found that the major causes of the conflict between Ife and Modakeke group include land issues, Ife-East Local Government, debate over Modakeke’s sovereignty, boundary disagreement etc.

Many conflict studies link the sources of social conflicts to sentiments of relative deprivation. They typically regard formal democratic institutions as states’ most important vehicle to reduce deprivation-motivated armed conflict against their governments. We argue that the wider concept of good governance is better suited to analyze deprivation-based conflict. The paper shows that the risk of renewed conflict in countries with good governance drops rapidly after the conflict has ended. In countries characterized by poor governance, this process takes much longer.

Legal Framework and Realities on the Ground
Publication évaluée par des pairsaoût, 2014République-Unie de TanzanieBeginning in the mid-1970s through to the 1980s, Tanzania experienced a severe socio-economic crisis. In an attempt to turn things around the abating economy and accelerate economic growth, the government embarked on a broad range of radical policy, legislation, and institution reforms, which opened doors for foreign direct investments (FDIs) and further initiatives have been taken to create an enabling environment for investments to flourish in the country.

In 2010, the Conference of the Parties to the Convention on Biological Diversity adopted the Aichi Biodiversity Targets as part of the Strategic Plan for Biodiversity 2011-2020. Target 11 calls for ‘at least 17 per cent of terrestrial and inland water areas and 10 per cent of coastal and marine areas’ to be conserved by way of ‘well-connected systems of protected areas and other effective area-based conservation measures’.

Like many of its neighbors, Tanzania is experiencing a well-documented surge of land grabbing related to investments in industries such as agriculture, biofuels, tourism, hunting, and forestry. Land grabbing in Tanzania is best understood and analyzed as both a symptom of and contributor towards wider political economic processes of change occurring in Tanzania.
