Land use maps from the Houay Pano catchment (Laos).<br>
“Annual crop”: Annual crops of upland rice (Oryza sativa L.), Job’s tears (Coix lacryma-jobi L.) or maize (Zea mays L.) grown in crop/fallow rotations; field preparation by slash-and-burn of the fallow, limited herbicide use, application only before sowing; no tillage except manual weeding, one to three times in the crop with a small curved hoe. No external fertilizers are applied. The duration of cultivation is one season, rarely two.<br>
“Fallow”: The spontaneous vegetation grows out after the last harvest (rice, maize, Job’s tears) until the next cultivation cycle. Initially, fallow duration gradually reduced from 8 to 2 years, then with the near abandonment of annual cultivation, fallow periods expanded and more and more land in the catchment became fallow.<br>
“Garden”: Mix of useful trees, shrubs, vines, and herbs, both cultivated and wild species, planted together near seasonal settlements.<br>
“Forest”: Mature forest maintained on steep, shallow and gravelly soils unsuitable for rice cultivation, but supplying a wide range of products; can be locally degraded because of over-exploitation.<br>
“Teak + annual crop”: Young teak plantations (&lt;4 years) with open canopy allowing annual crops.<br>
“Teak plantation”: Teak plantations (&gt;4 years), most often with no or limited understorey due to annual burning and/or weeding by farmers.<br>
“Village”: Village of Ban Lak Sip located downslope and gradually encroaching on the Houay Pano catchment.<br>
