Based on the best available remote sensing data from before 1990, the total area of formally eligible lands in Indonesia for the aff orestation and reforestation (A/R) Clean Development Mechanism (CDM) activities under the Kyoto protocol is about 46 M ha.

What policy lessons derive from the half-century of banana expansion in the coastal region? For that whole period bananas had a catalytic role in promoting coastal deforestation. At first, this was mostly through direct banana frontier expansion. Later the gradual settlement effects proved key. Modest credit subsidies, the large-scale construction and improvement of roads and ports, and a devalued exchange rate were probably the most important policies that contributed to the expansion of banana production, though they varied in importance during the different periods.

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 tree crop management appears to be the first stage towards a tree crop based production in Sumatra and Kalimantan. This changes the value of the forest/tree component of swidden agriculture, or the systems it evolves into.

Remote sensing and GIS tools have broadly helped hydrogeologists to delineate the groundwater prospective zones for watershed development and management. The origin, movement and existence of groundwater depends on several factors such as slope, drainage density, land use, geology, lineament density and geomorphology. Based on these, the mapping and identification of groundwater potential zones were carried out in a part of Nalgonda district, Telangana, India.
