Although the V. pubescens tree planting technology research is still in its early phase, the species appears to be appropriate to be grown by swidden farmers in West Kalimantan because of its wood and yield qualities. It also appears to be appropriate to be grown on imperata sites because of its ...

Appropriateness of Vitex pubescens production for swidden agriculturists
Swidden-fallow agroforestry among ribereño farmers in the Peruvian Amazon has been reported to show important regional variation. In this paper diversity in terra firme swidden-fallow agroforestry is described for a single village, Santa Rosa, located at the lower Ucayali river, Peru. Local fores...

Swidden-fallow agroforestry in Amazonian: diversity at close distance
Rubber is the most widespread smallholder tree crop in Southeast Asia. Some analysts have blamed the expansion of rubber for greatly contributing to the conversion of mature tropical forest in both Indonesia and Malaysia. The paper critically examines to what extent smallholder rubber production ...
Swidden agriculture in tropical Asia is a diverse practice, making it difficult to draw general conclusions on trends of the development of swidden fallow secondary forests (SFSF). There is, however, sufficient evidence to recognise trends of a gradual intensification often through the incorporat...

Estimates of the area of swidden fallow secondary forest in Indonesia are inaccurate, partly because swidden agricultural practices giving rise to the secondary forest are heterogeneous. Throughout Indonesia, swidden agriculture is evolving into more intensive land use. A mixed secondary forest t...
This book critically investigates the proposition that commercialisation of forest products contribute to both enhancing people's income and to conservation of tropical forests, using evidence from a case study from West Kalimantan, Indonesia. It draws the main conclusion that promoting commercia...

Forest products and local forest management in West Kalimantan, Indonesia: implications for conservation and development
The expansion of agriculture is widely held to be one of the causes of tropical deforestation. Simply stated, the progressive expansion of agriculture into areas of tropical forest can only occur when forests are slashed. There is little doubt that in many places an increased need for agricultura...
This special issue brings together 15 papers entirely dedicated to secondary forests in tropical Asia: 1. Tropical secondary forests in Asia: introduction and synthesis. 2. A conceptual framework for the assessment of tropical secondary forest dynamics and sustainable development potential in Asi...
