India

Impact of dynamic land use and land cover changes on the livelihood of local communities and ecosystem services is a major concern. This is particularly evident in most dryland agricultural systems in South Asia. We study land use/land cover (LULC) changes over the last two decades in a watershed (9589 ha) located in semi-arid eco-region in South India (Anantapuram district) using Landsat and IRS imagery. We captured additional data through field observations and focused group discussions.

Land-use change modelling in the Upper Blue Nile Basin

Diciembre, 2016

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.

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

Journal Articles & Books
Diciembre, 2014

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?
