Agro-Ecological Asessment of Phonxay District, Luang Phrabang Province, Lao PDR

When developing policies for agricultural land and land use planning, it is essential to have access to a land resource database. In Lao PDR, no such database previously existed, so we therefore attempted to make one and to implement its use by describing Phonxay District, Louang Phrabang Province, Lao PDR. All input data in the form of digital maps were transformed to Lao National Datum 1997. The potential evapotranspiration was calculated using the FAO Penman-Monteith Combination Method and was then, together with temperature and precipitation data, interpolated to cover northern Lao PDR. By using the database, growing period zones agro-ecological zoning, zones of soil and terrain constraints and two examples of land suitability assessment were performed for Phonxay District. The socio-economic and demographic characteristics of the district were also described. . Two growing period zones and 16 agro-ecological zones were mapped, in which seven of the zones had great potential for agricultural production. The constraint zones confirmed that 31.7 % of land in Phonxay was suitable for agriculture, being classified to zone of slight or no constrains. Bananas and pineapples suitability classification in the area corresponded well with the zones of no or slight constraint, and the agro-ecological zones suitable for agricultural production. The socio-economic comparisons of the district showed that villages with a mixed population are generally better of than other villages.
