The objective of this study is to assess land-use intensity and the related biodiversity in agricultural landscapes of the EU25 for the current situation (2000), and explore future trends, based on the four EURURALIS scenarios up to 2030. Data from the Farm Accountancy Data Network (FADN) were used to classify farm types in 100 regions of the EU15, according to agricultural intensity. For the ten New Member States (EU10), which are not yet considered by the FADN, country level data were used to obtain similar farm types.

Developing scenarios and visualisations to illustrate potential policy and climatic influences on future agricultural landscapes

The future evolution of our agricultural landscapes and countryside is the subject of considerable debate and policy discussion, alongside which is an increasing emphasis on the inclusion of public consultation and participation within planning and decision making systems. However, communicating different proposed policy options in a manner that facilitates informed decisions from stakeholders can be far from straightforward. This is particularly true with more abstract and uncertain issues such as potential impacts of climate change.

Contemporary land use/land cover types determine soil organic carbon stocks in south-west Rwanda

Soil organic carbon (SOC) constitutes a large pool within the global carbon cycle. Land use change significantly drives SOC stock variation. In tropical central and eastern Africa, how changes in land use and land cover impact on soil C stocks remains unclear. Variability in the existing data is typically explained by soil and climate factors with little consideration given to land use and management history.

Impact of Land Use Management and Soil Properties on Denitrifier Communities of Namibian Savannas

Namíbia

We studied potential denitrification activity and the underlying denitrifier communities in soils from a semiarid savanna ecosystem of the Kavango region in NE Namibia to help in predicting future changes in N₂O emissions due to continuing changes of land use in this region. Soil type and land use (pristine, fallow, and cultivated soils) influenced physicochemical characteristics of the soils that are relevant to denitrification activity and N₂O fluxes from soils and affected potential denitrification activity.

Nest site selection and the effects of land use in a multi-scale approach on the distribution of a passerine in an island arid environment

Journal Articles & Books
Dezembro, 2010

We examine the predictive ability of habitat-species relationship models in island semi-desert environments using as model species the Canary Islands stonechat (Saxicola dacotiae), an endemic bird inhabiting the arid island of Fuerteventura. We investigated nest site selection and the effects of land use on its distribution in a multi-scale approach using nest positions obtained during three consecutive breeding seasons.

Land use controls and residential land values in the Offinso South municipality, Ghana

Journal Articles & Books
Dezembro, 2013
Gana

Land use controls may have positive, negative or neutral impact on urban land values. The Offinso South Municipality (OSM) employs conventional zoning in its land management practices. This article investigates the land use control regime in and its impact on land values and the living standards of residents of the municipality. Empirical data were obtained from physical developers in the municipality via self-administered questionnaire. It also collected data from occupiers of amenity lands via guided interviews.

impact of permanent protection on cost and participation in a conservation programme: A case study from Queensland

Conservation covenants have become a popular tool to protect land in perpetuity. Understanding the impact of a covenant on price and enrolment in a conservation programme can help decision makers plan their interventions more carefully, and judge whether the extra longevity justifies the changed participation rate and cost. This paper uses the case study of a conservation auction in Queensland, Australia, to investigate the influence of a compulsory conservation covenant on bid price and participation.

European Landscape Convention, Wind Power, and the Limits of the Local: Notes from Italy and Sweden

The European Landscape Convention is the first international agreement to deal with all aspects of landscape planning, protection, and management. It emphasizes transparency, democracy, and good governance as integral parts of ‘landscape’. The ELC may inspire member states of the Council of Europe to develop better tools for planning land use and the environment; however its utility in practice is still largely untested. This article considers the relevance of the ELC to a major land use conflict in Europe today: the development of wind power.

Trophic assessment of streams in Uruguay: A Trophic State Index for Benthic Invertebrates (TSI-BI)

Human activities are radically changing natural land cover and increasing the delivery of soil, organic compounds, nutrients, toxic agrochemicals and other contaminants to aquatic ecosystems. The eutrophication of streams, rivers, lakes, reservoirs and costal zones is one of the most important consequences of human activities. In this study we assessed the trophic status of 28 wadeable stream reaches of the Santa Lucía basin, an important economic region of Uruguay. We developed a Trophic State Index of Benthic Invertebrates (TSI-BI), the first of its kind for South American lotic systems.

Combining CLUE-S and SWAT models to forecast land use change and non-point source pollution impact at a watershed scale in Liaoning Province, China

China

Non-point source (NPS) pollution has become a major source of water pollution. A combination of models would provide the necessary direction and approaches designed to control NPS pollution through land use planning. In this study, NPS pollution load was simulated in urban planning, historic trends and ecological protection land use scenarios based on the Conversion of Land Use and its Effect at Small regional extent (CLUE-S) and Soil and Water Assessment Tool (SWAT) models applied to Hunhe-Taizi River Watershed, Liaoning Province, China.

Protection of groundwater intended for human consumption: a proposed methodology for defining safeguard zones

Carbonate aquifers constitute a water reserve of essential importance for human supply. For this, it is necessary to establish suitable protection measures in order to achieve the good status of groundwater bodies intended for human supply according to the requirements of the Water Framework Directive.

Funding Science that Links to Decisions: Case Studies Involving Coastal Land Use Planning Projects

Journal Articles & Books
Dezembro, 2015

Many reports have noted that a significant portion of coastal science that is funded to help society address resource management issues does not actually link to decisions. A few studies and reports have offered valuable but general advice on what the funders of this science can do to better link science with decisions; there are fewer still published empirical case studies assessing the impacts of innovative funder methods for getting more science used by intended audiences.
