Abstract: Honduras is vulnerable to catastrophic losses associated with landslides and flooding in the aftermath of hurricanes (Fifi in 1974 and Mitch in 1998, most recently). Taking a watershed-scale approach to targeting conservation programs to promote stability on cropped steeplands in rural southern Honduras would reduce landslide and flooding risks, thus protecting export-earning downstream industries and investments. A case study of the Land Use and Productivity Enhancement project (1990–1998) was conducted to estimate the costs of extension programming to promote three conservation technologies – mulching, vetiver grass barriers, and rock walls – and to assess their efficacy (i.e., cost per ton of soil saved). Geographic Information System mapping tools were applied to suggest conservation priorities for steepland sites that are the most prone to landslides, both to maximize the soil saved per hectare protected and to minimize downstream damages.
