When he was the Crown Prince, King Rama X advised relevant agencies to survey and design a land utilisation plan, as well as water source development in search of proper guidelines/ methods for farming. He suggested appropriate development approach to be taken and types of crops to be planted should be considered based on relevant data acquired. On 18 July 2002, His Majesty the King donated 216 hectares (1,350 rai) of land to the Ministry of Agriculture and Cooperatives and suggested that this plot of land should be used for the conservation and sustainable utilisation of natural resources.
At present, the project has publicised agricultural research and technologies which are compatible with geographical and sociological context via agricultural clinics. The project’s 216 hectares (1,350 rai) of land is divided into five following zones:

Zone 1: The Royal Office Zone occupies 5.12 hectares (32 rai) of land or 2.37 per cent of the project’s total area. Located at the lower eastern part of the project site, atop a high hill, this zone thus offers a clear full view of the project site.

Zone 2: The Government Office Zone occupies 22.08 hectares (138 rai) of land or 10.22 per cent of the project’s total area. This zone is situated at the northeastern part of the project site, spreading across rolling steep slopes, with between 8-30 per cent incline. The majority of soil is rather deep and almost infertile. This zone is partially used for farming whilst some part still remains wasteland.

Zone 3: The Agricultural Development Zone occupies 22.24 hectares (139 rai) of land or 10.30 per cent of the project’s total area. Located in the northwestern part of the project site, it spreads from gentle to medium slopes. The majority of soil is rather deep and well drained, though almost infertile. This zone borders Ban Kong Hae Village.

Zone 4: The Agroforestry Farming/Community Food Bank Zone occupies 19.68 hectares (123 rai) of land or 9.11 per cent of the project’s total area. Covering over rolling slopes which stretch as far as the foot of the hill, this zone is mainly covered with deep and barren soil. Now there are some big trees which should be conserved. The main area of this zone being deteriorated forests should be rehabilitated so that they can become food sources for local communities.

Zone 5: The Forest Zone occupies 146.88 hectares (918 rai) of land or 68 per cent of the project’s total area. With hilly evergreen forests spreading over most part of the zone, it houses headwater sources, which must be conserved in a natural state to maintain a sustainable ecological system. For the parts which have become deteriorated, they must be reforested.

The Kaset Wichaya Project serves as the community’s technology-transfer and service centre. Local farmers have therefore properly been trained. Under the project, forest rehabilitation and occupational development have benefited the locals.
