Regional studies of land cover change are often limited by available data and in terms of comparability across regions, by the transferability of methods. This research addresses the role of roads and infrastructure improvements across a tri-national frontier region with similar climatic and biop...

Shifting cultivation is practiced by millions of farmers in the tropics and has been accused of causing deforestation and keeping farmers in poverty. The assumed positive relationship between fallow length and crop yields has long shaped such negative opinions on the sustainability and environmen...

This paper explores possible strategic interactions between the state and local community in games of tropical forest land appropriation. Three typical cases are discussed, corresponding to a development over time of increased resource competition and market integration. The local response to mor...

In this paper, we present an intensification model based on the intensity of exploitation and use of forests and forest lands as a relevant framework for analysing the appearance, dynamics, and evolution of different types of secondary forests. The systematic driving forces responsible for the di...

Much of mainland Southeast Asia's primary forest has been converted into secondary vegetation types in the past several decades. In the Lower Mekong Subregion, nearly 100 million ha of forest were significantly altered or removed, with depletion in terms of areal percent most severe in Thailand a...

Secondary forests are the largest and most dynamic natural forest ecosystems in the Philippines. This paper examines the characteristics and dynamics of secondary forests in the country. In the last century, the country lost 50% of its natural tropical forest cover. At present, the major land cov...
