Local knowledge of the impacts of eucalyptus expansion on water security in the Ethiopian highlands por Pagella, Tim, Cronin, M., Lamond, G., Sida, T., Sinclair, Fergus L.

“…Lack of long-term hydrological monitoring makes it difficult to determine impacts of changing land use on the water dynamics for many catchments in Africa. Here we use local ecological knowledge (LEK) to explore the impacts of rapid expansion of eucalyptus agroforestry on water security in the Ethiopian highlands. …”

Energy and carbon footprints of ethanol production using banana and cooking banana discard: A case study from Costa Rica and Ecuador por Graefe, Sophie, Dufour, D., Giraldo A., Muñoz, L.A., Mora P, Solís, H., Garcés, H., González, A.

“…Despite providing economic benefits to farmers through a biomass source that would have been otherwise lost, the study gave clear evidence that the ecological footprint of this ethanol production system is significantly influenced by the resource use during the production life cycle.…”

Earthworms accelerate soil porosity turnover under watering conditions por Bottinelli, N., Henry des Tureaux, Thierry, Hallaire, V., Mathieu, J., Benard, Y., Tran Duc Toan, Jouquet, Pascal

“…These results suggest that cast lifespan and associated porosity are of primary importance in the regulation of soil porosity turnover and the ecological functions that are under its control. Our findings suggest that in the field, the low stability of casts is likely to lead to a rapid compaction of the soil after rainfall events. …”

Transhumant pastoralism, sustainable management of natural resources and endemic ruminant livestock in the sub-humid zone of West Africa por Ayantunde, Augustine A., Asse, Rainer, Said, Mohammed Yahya, Fall, Abdou

“…Transhumant pastoralism is one of the dominant livestock production systems in West Africa, and it is characterized by seasonal and cyclical movement of varying degrees between complementary ecological areas. The common pattern of transhumance is moving herds from areas with pasture and water scarcity such as the Sahelian zone to areas where the forage and water are found, often in the sub-humid zone. …”
