The year 2011 highlighted ongoing challenges to global food security, from food price volatility, extreme weather shocks, and famine to unrest and conflicts. On the policy front, major developments at the global and national levels both offered grounds for encouragement and pointed to areas…
The year 2011 highlighted ongoing challenges to global food security, from food price volatility, extreme weather shocks, and famine to unrest and conflicts. On the policy front, major developments at the global and national levels both offered grounds for encouragement and pointed to areas…
Dry subtropical regions, originally hosting xerophytic vegetation, are currently characterized by diverse land cover/use patterns. Using existing biophysical and socio-economic databases, we explored how human contexts influenced land cover, vegetation composition and agricultural production in…
This paper analyzes the intersection of two parallel developments that have had a curious impact on agrarian politics in Colombia: on the one hand, attempts to appropriate land for ‘green’ ends such as biofuel production, which have become ubiquitous all across Latin America, and on the other,…
Payment for ecosystem services (PES) has been widely promoted as an effective and efficient model for conservation; however, few studies have empirically examined how the market-based approach interacts with farmer's decision-making processes and their abilities to sustain new conservation…

Vegetation exerts a strong control on water balance and key hydrological variables like evapotranspiration, water yield or even the flooded area may result severely affected by vegetation changes. Particularly, transitions between tree- and herbaceous-dominated covers, which are taking place at…
This study uses a combination of Landsat series data (Multispectral Scanner or MSS, Thematic Mapper or TM and Enhanced Thematic Mapper or ETM+) to map land-use and land-cover change (LULCC) from 1975 to 2001. It extends the land change record to 2008 using Chinese–Brazil Earth Resources…
We discuss coastal shellfisheries management and governance models in Latin America and the Caribbean (LAC) at different scales. Self-imposed governance with spatial property rights, internal rules and co-management resulted in successful local shellfisheries. At the national level, the long-…
Livestock production in Latin America has replaced tropical dry forests with conventional monocultures pastures (CP) that have degraded soils. As an alternative to CP, intensive silvopastoral systems (ISS) have been developed with multi-canopied vegetation that mimics native forest (F). The…
