Persistent Acacia savannas replace Mediterranean sclerophyllous forests in South America

América do Sul

Mediterranean ecosystems are global hotspots of biodiversity threaten by human disturbances. Growing evidence indicates that regeneration of Mediterranean forests can be halted under certain circumstances and that successional stages can become notoriously persistent. The Mediterranean sclerophyllous forest in central Chile is been largely transformed into savannas dominated by the invasive legume tree Acacia caven as result of interacting management and ecological factors.

Incentives, land use, and ecosystem services: Synthesizing complex linkages

Journal Articles & Books
Dezembro, 2013

Incentive schemes are increasingly used to motivate the supply of ecosystem services from agro-ecosystems through changes in land use and management. Here, I synthesize the complex effects of incentives on ecosystem services through their influence on land use and management. Linkages between incentives and land use change, and between land use change and ecosystem services can be one-to-many, many-to-one, and many-to-many. Change in land use and management can affect multiple ecosystem services, with both co-benefits and trade-offs.

Effects of administrative land-use and technical land-form constraints on timber production at the landscape level

Journal Articles & Books
Dezembro, 2011

This study quantified, across a landscape in Eastern Finland, the influence of administrative land-use and technical land-form constraints on timber production. Spatially explicit data about the nature conservation areas, land use plans and steep slopes were integrated with Multi-source National Forest Inventory (MS-NFI) data. The Finnish forestry model MELA was used in the calculations related to updating forest data and estimating different scenarios of timber production with and without constraints.

Landscape futures analysis: Assessing the impacts of environmental targets under alternative spatial policy options and future scenarios

Dezembro, 2011
Austrália

Environmental targets are often used in planning for sustainable agricultural landscapes but their impacts are rarely known. In this paper we introduce landscape futures analysis as a method which combines linear programming optimisation with scenario analysis in quantifying the environmental, economic, and social impacts associated with achieving environmental targets, on a landscape scale. We applied the technique in the Lower Murray in southern Australia.

Water planning in a changing climate: Joint application of cost utility analysis and modern portfolio theory

Journal Articles & Books
Dezembro, 2011

High nutrient loads are a widespread problem for many rivers and river catchments and cause damage to various ecological assets. Negative effects can be mitigated by changes in land management such as land use changes and/or implementation of intervention measures such as – amongst others – the construction of artificial wetlands and water treatment plants.

Examination of land equvalent ratio: The case of Havsa district of Edirne province

Policy Papers & Briefs
Dezembro, 2011

This study was applied in Edirne province Havsa district. For determination of land use efficiency of Havsa, satellite image and GIS were used. For this purpose the data of General Directorate of Rural Services which belongs to 1993 year, ASTER satellite images which belongs to 2008 year and topographic maps were used. For performing calculations in ERDAS software unclassified classification applied and 15 classes were formed. For performing supervised classification field work applied.

Spatial Analysis of Soil Subsidence in Peat Meadow Areas in Friesland in Relation to Land and Water Management, Climate Change, and Adaptation

Journal Articles & Books
Dezembro, 2015

Dutch peatlands have been subsiding due to peat decomposition, shrinkage and compression, since their reclamation in the 11th century. Currently, subsidence amounts to 1–2 cm/year. Water management in these areas is complex and costly, greenhouse gases are being emitted, and surface water quality is relatively poor. Regional and local authorities and landowners responsible for peatland management have recognized these problems. In addition, the Netherlands Royal Meteorological Institute predicts higher temperatures and drier summers, which both are expected to enhance peat decomposition.

FUZZY RULE BASE APPROACH FOR DEVELOPING A SOIL PROTECTION INDEX MAP: A CASE STUDY in the UPPER AWASH BASIN, ETHIOPIAN HIGHLANDS

Land use practices and vegetation cover distribution are considered to be the most important dynamic factors that influence the land degradation or the soil erosion of a region. In this study, a Soil Protection Index (SPI) is defined as a function of land use practices and intensity of vegetation cover. This index is used to map the relative degree of protection of topsoil from being eroded by external effects such as rainfall and overland flow. A fuzzy rule‐based model integrated within ArcGIS® has been set‐up and tested with the aim to develop SPI maps.

framework for evaluating and designing collaborative planning

Finlândia

Collaborative planning processes have been criticized for inefficiency, but attempts to improve them in planning of urban nature have been limited by lack of usable evaluation methodologies. This paper presents a framework for evaluating and designing collaborative processes in strategic planning of land use and nature areas. A framework with four key perspectives and their success criteria was developed with the help of literature and data from interviews and focus groups in two case areas in the Helsinki metropolitan area, Finland.

Planning the horticultural sector: Managing greenhouse sprawl in the Netherlands

Journal Articles & Books
Dezembro, 2013
Países Baixos

Greenhouses are a typical example of peri-urban land-use, a phenomenon that many planning systems find difficult to address as it mixes agricultural identity with urban appearance. Despite its urban appearance, greenhouse development often manages to evade urban containment policies. But a ban on greenhouse development might well result in under-utilisation of the economic value of the sector and its potential for sustainability. Specific knowledge of the urban and rural character of greenhouses is essential for the implementation of planning strategies.
