Carbon Storage by Urban Soils in the United States

Hong Kong
Estados Unidos de América

We used data available from the literature and measurements from Baltimore, Maryland, to (i) assess inter-city variability of soil organic carbon (SOC) pools (1-m depth) of six cities (Atlanta, Baltimore, Boston, Chicago, Oakland, and Syracuse); (ii) calculate the net effect of urban land-use conversion on SOC pools for the same cities; (iii) use the National Land Cover Database to extrapolate total SOC pools for each of the lower 48 U.S. states; and (iv) compare these totals with aboveground totals of carbon storage by trees.

Changes in soil organic carbon stocks and soil quality: land-use system effects in northern Ethiopia

Journal Articles & Books
Diciembre, 2012
Etiopía

In Tigray, Ethiopia, land degradation is a dominant environmental problem and hence the regional government has undertaken restoration measures on degraded soils since 1991. The present study was aimed to assess the impact of land uses and soil management practices on soil properties, and consequently on soil quality of degraded soils. The catchments selected were Maileba and Gum Selassa, and land uses included cultivated (CL), grazing (GL), plantation (PA) and area exclosure (AE). Replicated soil samples were collected from topsoil and profiles of four land-use types in both catchments.

Perspective directions for performing the cadastral function of land resource management

Policy Papers & Briefs

Belarús

The cadastre structure in the system of land and real estate management is determined by existing and technologically dependent kinds of works and procedures on registration, recording and valuation of real estate. A general approach to land evaluation of all categories is a differential rent income taking into account natural characteristics and location of pieces of land.

procedure to obtain a refined European land use/cover map

Journal Articles & Books

Europa

Available land use/cover maps differ in their spatial extent and in their thematic, spatial, and temporal resolutions. Due to the costs of producing such maps, there is usually a trade-off between spatial extent and resolution. The only European-wide, consistent, and multi-temporal land use/cover dataset available is the CORINE Land Cover (CLC) map. Despite the value and usefulness of CLC, its minimum mapping unit (MMU) of 25 hectares considerably limits its applications at large scales of analysis.

Effects of “Grain for Green” reforestation program on rural sustainability in China: an AHP approach to peasant consensus of public land use policies

Journal Articles & Books
Diciembre, 2014
China

Climate change will affect the regional ability to achieve the poverty reduction and sustainable development (SD) objectives. Thus, any action plans to achieve these objectives should make climate change policies an integral part of the development planning process. The best practices and measures of climate change policies should be implemented to ensure regional or community sustainability. In this paper, a case study that promotes the integration of carbon sequestration into sustainable forest management and rural development plan with multi-stakeholders participation is introduced.

Investigating urban growth scenarios in Wadi El Natrun area, Egypt, using the UPlan land use allocation model

Journal Articles & Books
Diciembre, 2013
Egipto

This study aims at establishing an approach for the analysis of urban growth dynamics to support urban planning decisions in Egypt. This approach is based on the UPlan model. It acknowledges the lack of historical land use detailed data in most of the Egyptian cities and is heavily based on socioeconomic and land use patterns collected from field surveys and census data. The model is tested on Wadi El Natrun city, an urban agglomeration located on the agricultural fringes of the Nile River. Several scenarios are generated based on changes in a set of attractors, discouragements, and masks.

Scale‐dependent effects of landscape composition and configuration on natural enemy diversity, crop herbivory, and yields

Journal Articles & Books
Diciembre, 2016

(1) Land‐use intensification in agricultural landscapes has led to changes in the way habitats and resources are distributed in space. Pests and their natural enemies are influenced by these changes, and by the farming intensity of crop fields. However, it is unknown whether the composition of landscapes (amount and diversity of land cover types) or their configuration (spatial arrangement of cover types) are more important for natural enemy diversity, and how they impact crop damage and yields. In addition, effects of interactions between local farming practices (organic vs.

Assessment of grassland use intensity by remote sensing to support conservation schemes

Grassland is a land cover in the area of conflict between agriculture and conservation, where intensification of land use is a major threat to grassland biodiversity. Grassland use intensity is a key factor for the conservation value of grassland, and detailed spatial data on grassland use intensity is needed to improve strategies for biodiversity conservation. A new remote sensing-based approach using multi-temporal high resolution RapidEye satellite data was developed in the present study that makes a large-scale assessment of grassland use intensity possible.

Balancing wood market demand and common property rights: a case study of a community in the Italian Alps

Italia

Common property rights have a long tradition in the Italian Alps, dating back to the Middle Ages, when alpine village communities managed common forests. On these properties, in accordance with rules aimed at regulating the collective use of resources, shareholders have the right of common use of the land. As many mountainous areas still rely on firewood for the heating of homes, the right to gather firewood from common forests is the most important common property right.

Habitat monitoring in the wider countryside: A case study on the pursuit of innovation in red deer management

Journal Articles & Books
Diciembre, 2013

Policy frameworks for protected areas, such as the EU habitats directive, ensure that environmental monitoring takes place to assess the condition of these sites. However, this monitoring rarely extends to the wider countryside, and there is no obligation for private landowners to detect trends in habitat condition. Using the diffusion of innovations model as an analytical framework we conducted a series of semi-structured interviews to consider the uptake of habitat impact assessment methods throughout a community involved in private land use pursuits in Scotland.

Using models to bridge the gap between land use and algal blooms: An example from the Loweswater catchment, UK

Journal Articles & Books
Diciembre, 2012

The goods and services that lakes provide result from complex interactions between meteorology, hydrology, nutrient loads and in-lake processes. Hydrology and nutrient loads are, in turn, influenced by socio-economic factors such as human habitation, water abstraction and land-management, within their catchments. Models provide a means of linking these different domains and also of forecasting and evaluating the effects of different management scenarios on lakes.
