Forest resources share attributes with many other resource systems that make difficult their governance and management in a sustainable, efficient and equitable manner. Destruction or degradation of forest resources is most likely to occur in open-access forests where those involved, or external authorities, have not established effective governance. Conventional theories applied to forest resources presumed that forest users themselves were incapable of organizing to overcome the temptations to overharvest.

Agricultural landscapes must provide food, fiber and energy to

a growing population in a changing climate, while potentially

serving as instruments for climate change mitigation. Agriculture

is the backbone of the Kenyan economy, contributing approximately

25% of the GDP annually and employing more than 75%

of the population (The Government of Kenya 2010). The development

of agriculture is also important for poverty reduction since

most of the vulnerable groups, like pastoralists, the landless, and

Using family balance (i.e., combined net farm and non-farm incomes less family expenses), an output from an integrated model, which couples water resource, agronomic and socio-economic models, its sensitivity and uncertainty are evaluated for five smallholder farming groups (AeE) in the Olifants Basin. The crop management practiced included conventional rainfed, untied ridges, planting basins and supplemental irrigation.

Adapting to climate risks is central to the goal of increasing food security and enhancing resilience of farming systems in East Africa. We examined farmers’ attitudes and assessed determinants of adaptation using data from a random sample of 500 households in Borana, Ethiopia, Nyando, Kenya, Hoima Uganda, and Lushoto, Tanzania. Adaptation was measured using a livelihood-based index that assigned weights to different individual strategies based on their marginal contributions to a household’s livelihood.

Five themes are identified for social, economic and policy research relating to miombo woodland management in southern Africa. They are: (1) patterns of local institutional change; (2) household use of woodland products; (3) markets for woodland products; (4) longer term dimensions to woodland use and exploitation and (5) policy and legislation. These themes are by no means definitive or exhaustive, but are described here as a means of focusing on the scope of future research, and as a basis for identifying priorities.

Geosoil permite almacenar, consultar e interpretar información tanto del suelo como de su entorno biofísico a diferentes escalas: parcela, finca, comunidad, municipio, departamento, región, país. Opera a partir de una base de datos relacional elaborada en ACCES 2000, compuesta por una serie de tablas principales estructuradas con información a diferentes niveles jerárquicos que permiten la caracterización de las propiedades del suelo.
