Preventing soil erosion by water
In Switzerland the RECARE researchers are testing the effectivness of reducing soil erosion by using small dams between ploughing furrows in potato fields.
Burnt areas in forests can reveal some extreme responses in runoff generation and associated sediment losses. Such responses exacerbate the direct effects of fire on vegetation and on the soil physical, chemical and biological properties, compromising their recovery from heat-induced changes. Post-fire soil erosion also represents a serious threat to off-site "values-at-risk", through flood generation and transfer of sediments, organic matter, nutrients and pollutants to downstream water bodies. Recent field trials in the Portugese case study area have clearly demonstrated that mulching with forest logging residues (widely available in the region) is highly effective in reducing erosion in recently burnt areas. The RECARE experiment is testing the effectiveness of mulching to reduce post-fire soil (fertility) losses. It involves mulching with eucalypt logging slash at 2 contrasting application rates.

The creation of agricultural terraces on steep terrain can provide an effective solution to preventing soil erosion. The experiment involves testing the effectiveness of maintenance/rehabilitation of dry-stone terraces. It involves a participatory monitoring process.
