Different drivers and places of land use change in South America have often been studied in isolation. Evidence suggests, however, that in many instances, both places and drivers are becoming increasingly interconnected. The growing diversification and internationalization of agricultural commodity chains is creating new linkages across production frontiers and sectors that have important implications for conservation.

How much do poor rural households rely
on environmental extraction from natural ecosystems? And how
does climate variability impact their livelihoods? This
paper sheds light on these two questions with household
income data from the Poverty and Environment Network
pantropical data set, combined with climate data for the
past three decades. The study finds that extraction of wild
resources (from natural forests, bushlands, fallows, etc.)

The major role tropical forests play in
biodiversity and climate change has led the world to search
for effective ways to slow down deforestation. Community
forest management (CFM) is an example of the broader concept
of community-based natural resources management (CBNRM). As
part of the decentralization policy in many countries,
mainly in Africa and Asia, CFM was expected to promote: (i)
a more effective stewardship of the resources by involving

Climate change is a core development
challenge in Tanzania, and the potential costs of inaction
are significant. Current climate variability (including
extreme events such as droughts and floods), already leads
to major economic costs in mainland Tanzania and in
Zanzibar. Individual annual events have economic costs in
excess of 1 percent of GDP, and occur regularly, reducing
long-term growth and affecting millions of people and

L’étude a été menée à l’aide de la plateforme MOSAICC (Modelling System for Agricultural Impacts of Climate Change) MOSAICC est une plateforme intégrée regroupant un ensemble de modèles et d’outils pour évaluer les impacts des changements climatiques à l’échelle nationale. Son architecture a été développée dans le but de permettre aux différents experts de collaborer à distance quel que soit leurs appartenance (ministères, universités, institutions de recherche) en utilisant leurs propres données.
