From government to governance in forest planning? Lessons from the case of the British Columbia Great Bear Rainforest initiative

Journal Articles & Books
Décembre, 2009

Much has been written about a supposed shift 'from government to governance' in many policy areas, including forest policy. However, the idea remains very much at the level of hypothesis as few empirical studies have confirmed the transition. Part of the problem is the multi-dimensional character of governance itself, which includes traditional 'government' as one of many possible governance modes.

Agricultural management affects the response of soil bacterial community structure and respiration to water-stress

Journal Articles & Books
Décembre, 2013

Soil microorganisms are responsible for organic matter decomposition processes that regulate soil carbon storage and mineralisation to CO₂. Climate change is predicted to increase the frequency of drought events, with uncertain consequences for soil microbial communities. In this study we tested the hypothesis that agricultural management used to enhance soil carbon stocks would increase the stability of microbial community structure and activity in response to water-stress.

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.

Ecological assessment of urban development in Antalya and suggestions in the scope of sustainability

Policy Papers & Briefs
Décembre, 2012
Turquie

Half of the worlds' population lives in cities. As the urban developments may have negative effects on the nature, ecological approaches are being considered in urban development studies. Ecological planning in and around the cities has a character of Landscape Planning that aims to protect natural elements, to improve ecological conditions, to prevent or reduce the effects of factors deteriorating environmental quality and to find out the potential of nature in order to conserve it.

Across the grain: Multi-scale map comparison and land change assessment

Journal Articles & Books
Décembre, 2016

Changes in the spatial distribution of land cover and land use can have significant impacts on ecological processes at multiple scales; estimating these changes provides critical data for both monitoring and understanding land-use effects on these processes. One approach to mapping landcover changes, particularly useful over longer periods of time, is comparison of existing landcover maps, (post-classification change analysis).

Cross-cultural perceptions of ecosystem services: A social inquiry on both sides of the Israeli–Jordanian border of the Southern Arava Valley Desert

Décembre, 2013
Israël
Jordanie

This research explores local resident perspectives on ecosystem services (ES) in the hyper-arid Arava Valley/Wadi Araba, which spans across both Israel and Jordan. Identifying and characterizing ES, an increasingly popular precursor for crafting sustainable natural resource management and land use policy, is an inherently multi-disciplinary endeavor. Our goal is to apply social research tools, in particular in-depth interviews with local residents, to understand their perspectives concerning ES.

Urban land uses with respect to ecology: A case study for Çanakkale city centre

Policy Papers & Briefs
Décembre, 2011
Turquie

This investigation was conducted for both constituting an urban land use planning and criticizing the appropriateness of the uses with respect to ecology by taking into consideration the ecological factors in the centre and the periphery of Çanakkale city. A method based on "Maximum Values Map Approximation Method" was used in this present study. A suggested land use map of the study area was constructed for these usage types according to the arrangements of their priorities by the experts.

Future European agricultural landscapes--What can we learn from existing quantitative land use scenario studies

Europe

The structure of agricultural production and spatial patterns of agricultural land use in Europe are expected to face major changes over the next decades due to changes in global trade, technology, demography and policies. This paper presents a set of 25 scenarios comprising information on quantitative land use changes in Europe. The scenarios have been selected from studies with different foci, operating on both different spatial scales and different time horizons.
