While slash-and burn farmers convert forest to agriculture, they also regenerate significant areas of secondary fallow forests on their farms. Under what conditions does secondary forest cover persist on slash-and-burn farms?. Survey data from Para, Brazil show that secondary forests accupy 20% o...

According to the IPCC’s Fifth Assessment Report, changes in the climate over the last 30 years have already reduced global agricultural production by 1 – 5 % per decade relative to a baseline without climate change. In addition, recent studies indicate that even a 2 degrees increase in global tem...

The regeneration of secondary forests (SF) on previously cleared land in the Amazon is a promising development within the generally pessimistic scenario about tropical deforestation. This has stimulated efforts to augment the value of SF to farmers to induce them to increase the area in SF. The o...

Recent studies have shown that although swidden agriculture contributes to tropical deforestation in Latin America, swidden farmers also regenerate significant areas of secondary forests on their farms as part of the following process. This paper discusses the opportunities and constraints to far...

While many goverment policies stimulating deforestation have been reserved, private sector lobbies for uncontrolled logging and soybean export corridors threaten the Amazon. Under a favorable scenario (macroeconomic stabilization, controlled logging and road building, sustainable technologies, gl...

There is an ongoing debate on what constitutes sustainable intensification of agriculture (SIA). In this paper, we propose that a paradigm for sustainable intensification can be defined and translated into an operational framework for agricultural development. We argue that this paradigm must now...
