Se efectuaron análisis tafonómicos sobre restos de fauna de vertebrados del alero Punta de la Peña 4 en Antofagasta de la Sierra, dentro de sus niveles estratigráficos vinculados a economías agropastoriles (capas 1 a 3). A partir de su estudio se obtuvo información ateniente a las pautas culturales de consumo y procesamiento humano sobre rebaños de llamas , y las actividades sobre caza de vicuñas. En los resultados se observó un predominio del consumo y procesamiento de llamas por sobre el de las vicuñas.
Background Pastoralists have long inhabited vast areas of western China, including the Tibetan Plateau region. Their traditional land use practices and cultural conservation ethic have helped to protect the natural resource base upon which they depend and the wildlife that co-exist with them in the grassland landscapes.
These Regulations make provision for the declaration, administration and management of wildlife management areas and the establishment of Community Based Organizations for such administration and management. They also provide for non-consumptive and consumptive utilisation of resources of wildlife management areas, the resolution of disputes and management of conflicts in such areas and define offences.Any village intending to designate an area as a Wildlife Management Area shall first establish a Community Based Organization in the manner prescribed under the Trustees’ Incorporation Act.
These By-laws, approved by the Minister in terms of section 90 of the Rural District Councils Act, shall apply to communal and resettlement land within the Makonde Rural District Council. They allow the Makonde Rural District Council to prepare a plan for- (a) all communal or resettlement land within the Council area; or (b) any ward or combination of wards in communal and resettlement land within the Council area; or (c) any part of award or wards in communal and resettlement land within the Council area. The By-laws set out the procedure for preparation and adoption of the Plan.
Decentralized stormwater management is based on the dispersal of stormwater management practices (SWMP) throughout a watershed to manage stormwater runoff volume and potentially restore natural hydrologic processes. This approach to stormwater management is increasingly popular but faces constraints related to land access and citizen engagement. We tested a novel method of environmental management through citizen-based stormwater management on suburban private land.
Global climate change, especially the phenomena of global warming, is expected to increase the intensity of land-falling hurricanes. Societal adaptation is needed to reduce vulnerability from increasingly intense hurricanes. This study quantifies the adaptation effects of potentially policy driven caps on housing densities and agricultural cover in coastal (and adjacent inland) areas vulnerable to hurricane damages in the Atlantic and Gulf Coastal regions of the U.S.
Improving the long-term sustainability and resilience of smallholder agriculture in Africa is highly dependent on conserving or improving the quality of the natural resource. Conservation agriculture is conceived around more integrated and effective management strategies for provisioning both food and other ecosystem services. If unattended to, land degradation would reduce agricultural productivity and increase pressure on marginal environments in the Tigray highlands of Ethiopia, adversely affecting food security and livelihoods of smallholder farmers.
Soils of the world’s agroecosystems (croplands, grazing lands, rangelands) are depleted of their soil organic carbon (SOC) pool by 25–75% depending on climate, soil type, and historic management. The magnitude of loss may be 10 to 50tonsC/ha. Soils with severe depletion of their SOC pool have low agronomic yield and low use efficiency of added input.
