Poverty implications of agricultural land degradation in Ghana
Assessing the risks of soil erosion and small reservoir siltation in a tropical river basin in Mali using the SWAT model under limited data condition
Common-pool resources, livelihoods, and resilience
Common-pool resource management is a critical element in the interlocked challenges of food security, nutrition, poverty reduction, and environmental sustainability. This paper examines strategic policy choices and governance challenges facing Cambodia‘s forests and fisheries, the most economically important subsectors of agriculture that rely on common-pool resources. It then outlines policy priorities for institutional development to achieve improvements in implementing these goals.
USAID Country Profile: Property Rights and Resource Governance - Lao PDR
OVERVIEW: The Lao People’s Democratic Republic (Lao PDR) is a landlocked country situated in Southeast Asia, bordering Thailand, Cambodia, Vietnam, China and Myanmar. Despite a recent increase in the rate of urbanization and a relatively small amount of arable land per capita, most people in Lao PDR live in rural areas and work in an agriculture sector dominated by subsistence farming. Lao PDR’s economy relies heavily on its natural resources, with over half the country’s wealth produced by agricultural land, forests, water and hydropower and mineral resources.
USAID Country Profile: Property Rights and Resource Governance - Thailand
OVERVIEW: Thailand is facing the challenges of a transition from lower- to upper-middle-income status. After decades of very rapid growth followed by more modest 5–6% growth after the Asian financial crisis of 1997–98, Thailand achieved a per capita GNI of US $3670 by 2008, reduced its poverty rate to less than 10% and greatly extended coverage of social services. Infant mortality has been cut to only 13 per 1000, and 98% of the population has access to clean water and sanitation.
Experiences in monitoring and assessment of sustainable land management
Although sustainable land management (SLM) is widely promoted to prevent and mitigate land degradation and desertification, its monitoring and assessment (M&A) has received much less attention. This paper compiles methodological approaches which to date have been little reported in the literature. It draws lessons from these experiences and identifies common elements and future pathways as a basis for a global approach. The paper starts with local level methods where the World Overview of Conservation Approaches and Technologies (WOCAT) framework catalogues SLM case studies.
Impacts of Deforestation and Land Cover Change on Mountain Soils in Hrazdan, Armenia
The impacts of deforestation and land cover change upon underlying soils were examined on one hillside in central Armenia. Soil characteristics in three land cover areas—forest, coppice, and pasture—were recorded and soil samples were analyzed. Deforestation and land cover change were found to increase erosion rates. From soil horizon and structural characteristics, it can be estimated that 40 cm of soil have been lost in the pasture and 20 cm have been lost in the coppice compared to the forest. Soil organic carbon was also affected by deforestation and land cover change.
Research on land use decisions to carry out remote sensing:A case study on Gediz Delta
Gediz Delta is place of empties itself into the sea of Gediz River. Its one of the important wetland of Turkey which under the protection of Ramsar Convention. It has lots of lagoones, salt marshes, freshwater marshes, large saltpans and also ornitotourism place Kuş Cenneti. Gediz Delta has rich flora and fauna biodiversity because of this its important place for natural life sustainability.
Sequestering carbon in soils of agro-ecosystems
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.
Climate change and trade in agriculture
Agricultural productivity in both developing and developed countries will have to improve to achieve substantial increases in food production by 2050 while land and water resources become less abundant and the effects of climate change introduce much uncertainty. Already less resilient production areas will suffer the most, as temperatures will rise further in tropical and semi-tropical latitudes and water-scarce regions will face even drier conditions.
Integrating land management and land-cover classes to assess impacts of land use change on ecosystem services
The paper presents a case study in which land use strategies to mitigate Climate Change effects are developed for a model in Saxony, Germany. In this region, the degree of freedom to respond to Climate Change with land-cover changes is very small. Based on a participatory process, an approach was developed to extend land-cover classes (e.g. forest, agriculture) by land management classes. In this paper, the focus is on the forest management classification.
