The rate of forest cover loss in the humid tropics of Cameroon is one of the highest in Central Africa. The aim of the large-scale, two-year research project described here was to understand the effect of the country's economic crisis and policy change on small-scale agricultural systems and land...

Economic crisis, small-scale agriculture, and forest cover change in Southern Cameroon
The Amazon is the largest tropical forest area on Earth, and is undergoing rapid deforestation since the last four decades. These conversions are mostly located in frontier areas distributed along the so-called “arc of deforestation”. Within this large zone, various land use change processes are ...

Contrasted land use and development trajectories in the Brazilian Amazon
The department of Santa Cruz in Bolivia makes part of the Amazon basin, and it embraces a large portion of the Bolivian lowland forest, with most of its area covered by semideciduous forest. The agricultural development, and hence deforestation in Santa Cruz, does not follow any similar path of o...

This paper analyzes geo-referenced data to elucidate the relations between deforestation and access to roads and markets, attributes of the physical environment, land tenure, and zoning policies in Santa Cruz, Bolivia. It presents separate models for Santa Cruz as a whole and for seven different ...

Modeling deforestation at distinct geographic scales and time periods in Santa Cruz, Bolivia
Integration of information from household surveys and data on land-cover changes derived from remote sensing helps to understand the causes and processes of land-use/land-cover changes. A household survey covering 552 households in 33 villages was carried out in the East Province of Cameroon. Thi...

Impact of macroeconomic change on deforestation in South Cameroon: integration of household survey and remotely-sensed data
The Amazon is the largest tropical forest area on earth, and has been undergoing rapid deforestation for the last four decades. In the Brazilian Amazon, large-scale pasture for cattle ranching and soybean production are the main land uses, leading to a yearly deforestation rate of 0.5%. These con...

Crossing spatial analyses and livestock economics to understand deforestation processes in the Brazilian Amazon: the case of Sao Felix do Xingu in South Para
The objective of this study is to better understand the complexity of deforestation processes in southern Cameroon by testing a multivariate, spatial model of land-cover change trajectories associated with deforestation. The spatial model integrates a spectrum of independent variables that charac...
The authors used a configurational comparative approach, the Qualitative Comparative Analysis (QCA), to study multiple causal interactions characterizing deforestation in the Brazilian Amazon. Their data set is based on seven local case studies at three time periods. Results reveal a limited numb...
