Linkages between changes in land use, biodiversity and land degradation on the slopes of Mount Kilimanjaro, Tanzania
Large scale land acquisitions and REDD+: a synthesis of conflicts and opportunities
Large scale land acquisitions (LSLA), and Reducing Emissions from Deforestation and forest Degradation (REDD+) are both land based phenomena which when occurring in the same area, can compete with each other for land. A quantitative analysis of country characteristics revealed that land available for agriculture, accessibility, and political stability are key explanatory factors for a country being targeted for LSLA. Surprisingly LSLA occur in countries with lower accessibility.
Land-use and land-cover dynamics in response to changes in climatic, biological and socio-political forces: The case of southwestern Ethiopia
Few studies of land-use/land-cover change provide an integrated assessment of the driving forces and consequences of that change, particularly in Africa. Our objectives were to determine how driving forces at different scales change over time, how these forces affect the dynamics and patterns of land use/land cover, and how land-use/land-cover change affects ecological properties at the landscape scale.

Land-use change modelling in the Upper Blue Nile Basin
Land-use and land-cover changes are driving unprecedented changes in ecosystems and environmental processes at different scales. This study was aimed at identifying the potential land-use drivers in the Jedeb catchment of the Abbay basin by combining statistical analysis, field investigation and remote sensing. To do so, a land-use change model was calibrated and evaluated using the SITE (SImulation of Terrestrial Environment) modelling framework.
Let's conserve the environment by finding solutions to end poverty
This participatory video was filmed, produced, and directed by a group of 12 farmers and community members from the villages of Mpulula, Malaswa, Kapalula, and Gwauya, Malawi. With this video they want to communicate the message that “we can conserve the environment by finding solutions to end poverty.” The film features farmers describing the value of trees, vetiver grass strips, collective action and the importance of alternative livelihoods to the destructive practice of charcoal making.

Land-use change trajectories up to 2050: insights from a global agro-economic model comparison
Changes in agricultural land use have important implications for environmental services. Previous studies of agricultural land-use futures have been published indicating large uncertainty due to different model assumptions and methodologies. In this article we present a first comprehensive comparison of global agro-economic models that have harmonized drivers of population, GDP, and biophysical yields. The comparison allows us to ask two research questions: (1) How much cropland will be used under different socioeconomic and climate change scenarios?

Low cost animal drawn implements for Vertisol management and strategies for land use intensification
The main aim of land preparation is to modify and manipulate the land features so as to create favorable environment for seed establishment and crop growth. The research and Development in this field must take into account the traditional practices used by the farming community. This case study gives a brief description of farmers' management of Vertisols and soils with 'Vertic' properties and the Development of the low cost broad bed maker (BBM) for facilitating surface drainage.
