Beyond REDD+ readiness: land-use governance to reduce deforestation in Peru

Journal Articles & Books
Dezembro, 2014
Peru

Peru contains the fourth largest area of tropical forest in the world, yet faces a worsening net deforestation rate. In 2008, to address this threat, the national government announced its ambition to reduce deforestation to zero by 2021. Via literature review and key informant interviews, this study assess two years of REDD+ readiness preparations according to six readiness functions. A mixed pattern of outcomes emerge. Although significant advances were made by various local-level initiatives, national-level efforts continue to struggle.

Changes in carbon stocks of Danish agricultural mineral soils between 1986 and 2009

Journal Articles & Books
Dezembro, 2014

To establish a national inventory of soil organic carbon (SOC) stocks and their change over time, soil was sampled in 1986, 1997 and 2009 in a Danish nation‐wide 7‐km grid and analysed for SOC content. The average SOC stock in 0–100‐cm depth soil was 142 t C ha⁻¹, with 63, 41 and 38 t C ha⁻¹ in the 0–25, 25–50 and 50–100 cm depths, respectively. Changes at 0–25 cm were small. During 1986–97, SOC in the 25–50‐cm layer increased in sandy soils while SOC decreased in loam soils. In the subsequent period (1997–2009), most soils showed significant losses of SOC.

importance of land cover change across urban–rural typologies for climate modeling

Journal Articles & Books
Dezembro, 2013

Land cover changes affect local surface energy balances by changing the amount of solar energy reflected, the magnitude and duration over which absorbed energy is released as heat, and the amount of energy that is diverted to non-heating fluxes through evaporation. However, such local influences often are only crudely included in climate modeling exercises, if at all. A better understanding of local land conversion dynamics can serve to inform inputs for climate models and increase the role for land use planning in climate management policy.

Farm and Forest in Central Africa: Toward an Integrated Rural Development Strategy

África Central

The authors explore three problems confronting scientists working in the central African humid forest zone and show their interconnectedness in the context of the sociopolitical history of the area. These problems emerge from different domains at different spatial scales: agricultural development, natural resource management, and landscape scale conservation. Land and livelihoods are severely constrained in central Africa. Agriculture is rarely remunerative: prices are low, technology limited, land rights contested, and labor scarce.

Determination and mapping of land suitability classes for agricultural utilization in Ankara Imrahor Valley and its vicinity

Dezembro, 2008
Turquia

That was to perform a determination of land suitability classes for agricultural land uses in Ankara Imrahor valley and vicinity with this study. First of all detailed survey and mapping of research area was performed with aid of satellite data and topographic maps then four different soil serials and their fourteen different mapping units were described. For this units, 38 different land uses were describe as their soil and meterological properties and calculated their suitability for this region and determined and mapping their land suitability classes for agricultural purposes.

Modeling of non‐point source nitrogen pollution from 1979 to 2008 in Jiaodong Peninsula, China

China

Efforts to reduce land‐based non‐point source (NPS) pollutions from watersheds to coastal waters are ongoing all around the world. In this study, annual yield of NPS nitrogen (NPS‐N) pollution in Jiaodong Peninsula, China from 1979 to 2008 was estimated. The results showed that: from 1979 to 2008, NPS‐N yields exhibited significant inter‐annual variations and an increasing trend on decadal scale. High NPS‐N yield was mainly found in east and south parts, as well as the urbanized coastal regions in Jiaodong Peninsula.

Temporal-spatial variability of desertification in an agro-pastoral transitional zone of northern Shaanxi Province, China

China

Desertification has been widely treated as one of the major environmental hazards in the world by scientific communities and the public. Monitoring the dynamics and causes of desertification is essential to provide important instruction for desertification control strategies and rational planning of land use in arid and semi-arid areas.

Impact of the European Water Framework Directive on local-level water management: Case study Oxunda Catchment, Sweden

Suécia

The Water Framework Directive (WFD) of the European Union provides a common framework for water policy that focuses on holistic and integrated water management in river basins. In many member states, implementation of the WFD has shifted the main responsibility for local water issues from the municipal level to the regional or supra-regional levels. In this study, we investigated how the implementation of the WFD has influenced local-level water management including the interpretation of the new environmental quality standards.

How has Oregon's land use planning system affected property values?

Journal Articles & Books
Dezembro, 2012

Oregon's landmark land use planning system has been criticized for imposing large negative effects on landowners’ property values, although evidence to support these claims has been lacking. This paper examines longitudinal data for undeveloped parcels since before adoption of the planning system. The sample includes parcels under different land use regulations, and it compares Oregon to Washington.

A case study on determining effective active green space opportunities in upper northwest urban development area of Adana

Policy Papers & Briefs
Dezembro, 2009
Turquia

This study aimed determining the effectiveness of active green space opportunities (parks, children's gardens, sport and playgrounds) in the Upper Northwest Urban Development Area of Adana. Existing active green spaces were obtained as green space values per capita and indexed at the neighborhood level. The effectiveness of active green space opportunities for each neighborhood were estimated by the distances between centers of neighborhoods and the threshold distance between any active green space and the furthest residential housing.
