Land suitability analysis for agriculture in the Abbay basin using remote sensing, GIS and AHP techniques

Journal Articles & Books
Décembre, 2016
Éthiopie

To meet growing population demands for food and other agricultural commodities, agricultural land-use intensification and extensification seems to be increasing in the Abbay (Upper Blue Nile) basin in Ethiopia. However, the amount, location and degree of suitability of the basin for agriculture seem not well studied and/or documented. From global data sources, literature review and field investigation, a number of agricultural land suitability evaluation criteria were identified.

Perception of local community and the willingness to pay to restore church forests: the case of Dera district, northwestern Ethiopia

Journal Articles & Books
Décembre, 2016

In the Ethiopian highlands, church forests have a substantial contribution to landscape restoration, and conservation of endangered indigenous tree species and biodiversity. However, the environmental and economic benefits of church forests are declining due to a combination of economic, environmental, and cultural factors. This study was conducted in Dera district, Ethiopia, to assess the perception of local communities on church forests and investigate the willingness of local communities to pay to manage and protect church forests.

Relearning traditional knowledge for sustainability: honey gathering in the Miombo Woodland of Northern Mozambique

Conference Papers & Reports
Décembre, 2016
Mozambique

Mozambique's Niassa Reserve contains Africa's best preserved miombo woodlands. Half of the households there gather wild honey from natural hives for consumption and income. However, most collectors used destructive techniques: setting fire to the grasses under the hive tree to create smoke and then felling the tree. Cutting trees to obtain honey was the principal source of tree mortality. Trees grow very slowly, about 0.25 cm diameter at breast hight [dbh] per year, meaning an average hive tree was nearly 200 years old.

Soil restoration after seven years of exclosure management in northwestern Ethiopia

Journal Articles & Books
Décembre, 2016

Ecological restoration through exclosure establishment has become an increasingly important approach to reversing degraded ecosystems in rangelands worldwide. The present study was conducted in northwestern Ethiopia where policy programs are aiming to restore degraded lands. Changes in soil properties following establishing exclosures on communal grazing lands were investigated. A space-for-time substitution approach was used to monitor changes in soil properties after conversion of communal grazing lands to exclosures with ages of establishment ranging from 1 to 7-years.

Suitability of watershed models to predict distributed hydrologic response in the Awramba Watershed in Lake Tana Basin

Journal Articles & Books
Décembre, 2016
Éthiopie

Planning effective landscape interventions is an important tool to fight against land degradation and requires knowledge on spatial distribution of runoff. The objective of this paper was to test models that predict temporal and spatial distribution of runoff. The selected models were PED-WM, HBV-IHMS and SWAT. We choose 7 km2 Awramba watershed in the Lake Tana basin with detailed hydrological information for testing these models.

The Economic Case for Landscape Restoration in Latin America

Degraded lands—lands that have lost some degree of their natural productivity through human activity—account for over 20 percent of forest and agricultural lands in Latin America and the Caribbean. Some 300 million hectares of the region’s forests are considered degraded, and about 350 million hectares are now classified as deforested. The agriculture and forestry sectors are growing and exerting great pressure on natural areas. With the region expected to play an increasingly important role in global food security, this pressure will continue to ratchet up.

The work of the Mekong Partnership for the Environment, and the work of
PACT, has been devoted to the role of EIA in achieving sustainable
development. Through the work of PACT and many other practitioners and
communities, the profile of EIA has been raised. Many discussions are occurring
to improve the standard and value of EIA. In particular, the development of
Regional Guidelines on Public Participation and the drafting of national
guidelines on Public Participation in EIA for both Cambodia and Myanmar are all

Host country governance and the African land rush: 7 reasons why large-scale farmland investments fail to contribute to sustainable development

Afrique

Contributes to the research gap on host country governance dynamics by synthesizing results and lessons from 38 case studies conducted in Ethiopia, Ghana, Nigeria, and Zambia. It shows how and why large-scale farmland investments are often synonymous with displacement, dispossession, and environmental degradation and, thereby, highlights 7 outcome determinants that merit more explicit treatment in academic and policy discourse.
