While soil erosion is reasonably well documented at the plot scale, data remain scarce at the catchment scale and predominantly stem from short-term studies. In this context, the "Management of Soil Erosion Consortium" network, which recently became the Multi-Scale Environmental Changes observatory (MSEC3, http://www.msec3.net/portal/), was established in the late 1990s in three upland catchments of Laos, Thailand and Vietnam. New land management options, introduced in consultation with farmers, were tested in terms of runoff and erosion. These included tree plantations, planted fodder, and no-till cover systems. The MSEC demonstrated that converting land from shifting cultivation systems to short rotations, or permanent cropping of species such as maize, cassava or teak, can result in increased erosion far beyond any tolerable rate of soil loss. Fodder and no-till cover systems are efficient means of controlling soil losses, yet several socio-economical obstacles can limit their adoption.
