Vegetation changes in Conservation Reserve Program lands in interior Alaska

Journal Articles & Books
December, 2010
United States of America

Over 14 million hectares of erosion prone cropland in the United States has been converted into grasslands through the Conservation Reserve Program (CRP) administered by the United States Department of Agriculture, however, studies of the effects of CRP enrollment on plant communities and subsequent plant succession are largely lacking.

Optimization of net returns from wildlife consumptive and non-consumptive uses by game reserve management

Southern Africa

Landowners and game reserve managers are often faced with the decision whether to undertake consumptive (such as hunting) and/or non-consumptive (such as tourism) use of wildlife resources on their properties. Here a theoretical model was used to examine cases where the game reserve management allocated the amount of land devoted to hunting (trophy hunting) and tourism, based on three scenarios: (1) hunting is separated from tourism but wildlife is shared; (2) hunting and tourism co-exist; and (3) hunting and tourism are separated by a fence.

Enjeux fonciers, exploitation des ressources naturelles et Forêts des Communautés Locales en périphérie de Kinshasa, RDC

Democratic Republic of the Congo

Land issues, exploitation of natural resources, and Forests of Rural Communities in the periphery of Kinshasa, DRC. Peri-urban forests are under strong anthropic pressure. Any activity needs a previous identification of stakeholders, landscape perception, socio-economic trends in local communities and their relationships with land and natural resources. Kinshasa (capital of Democratic Republic of Congo, DRC) is a 10 millions inhabitants city with rapid growth and increasing impacts on surrounding villages linked with forest natural resources.

Impact of soil management practices on physical and chemical properties of soils formed in marls, conglomerates or schists in sloping olive groves

Greece

In west Crete, Greece we studied the effect of land management practices, tillage and no tillage, on physical and chemical properties of autochthonous soils that were formed in marls, conglomerates or schists in slopes higher than 10%. Soil organic matter content was higher in the case of no tillage in soils formed on conglomerates. The conglomerates soil content in available P was 8.27 mg kg-1 in the case of no-tillage and 2.87 mg kg-1 in tillage while in soils formed on marls it was 26.65 and 16.83 mg kg-1, respectively.

carbon budget of a winter wheat field: An eddy covariance analysis of seasonal and inter-annual variability

Journal Articles & Books
December, 2012

Arable land occupies large areas of global land surface and hence plays an important role in the terrestrial carbon cycle. Therefore agro-ecosystems show a high potential of mitigating greenhouse gas emissions while optimizing agricultural management. Hence, there is a growing interest in analyzing and understanding carbon fluxes from arable land as affected by regional environmental as well as management conditions.

Meadow management and occurrence of corncrake Crex crex

Journal Articles & Books
December, 2007

The aim of this study was to analyse the occurrence of corncrakes in two Swedish meadow sites managed by mowing and grazing, but also with abandoned meadows. Most corncrakes (58%) on meadows were found in unmanaged areas without subsidies to the farmers (i.e. areas with tall vegetation). Several corncrakes (62%) were found in restored areas, managed for less than 10 of the last 40 years, fewer (38%) in areas under continuous management.

Potential Impacts and Management Implications of Climate Change on Tampa Bay Estuary Critical Coastal Habitats

Journal Articles & Books
December, 2014

The Tampa Bay estuary is a unique and valued ecosystem that currently thrives between subtropical and temperate climates along Florida’s west-central coast. The watershed is considered urbanized (42� % lands developed); however, a suite of critical coastal habitats still persists. Current management efforts are focused toward restoring the historic balance of these habitat types to a benchmark 1950s period. We have modeled the anticipated changes to a suite of habitats within the Tampa Bay estuary using the sea level affecting marshes model under various sea level rise (SLR) scenarios.

Towards a social–ecological resilience framework for coastal planning

Journal Articles & Books
December, 2013

It is increasingly recognised that designing and implementing adaptive land management and development policies for the coastal zone requires an interdisciplinary and integrated approach. Yet, integrative thinking and action often remain problematic due to the competing interests and ambitions involved in coastal zone planning and management and the legacy of established development on the coast.

Ranch Ownership Change and New Approaches to Water Resource Management in Southwestern Montana: Implications for Fisheries

Journal Articles & Books
December, 2007

This article reports on a survey of ranch owners in high amenity areas in southwestern Montana that have experienced marked ownership change over the last two decades. Specifically, we focus on findings from a set of questions targeting water resource and riparian area management. After reviewing the results, we consider how new owners may be managing water resources differently than longtime owners and what the ecological implications of this shift in management might be for Montana's prized wild fisheries.

Land Manager and Researcher Perspectives on Invasive Plant Research Needs in the Midwestern United States

Journal Articles & Books
December, 2009

In 2006, the Midwest Invasive Plant Network's Research Committee conducted a web-based survey to help identify research needs and interactions between land managers and researchers working to manage invasive plants in the Midwest. Of 192 responses, 30% identified themselves as researchers and 70% identified themselves as managers. Researchers and managers rated working together on invasive plant issues as high or medium in importance, but neither group rated the current level of cooperation as high, with over 90% describing current cooperation as low or medium.

What can forest values tell us about human well-being? Insights from two biosphere reserves in Madagascar

Journal Articles & Books
December, 2016
Madagascar

The article discusses the relationship between conceptions of forest values among local people in Madagascar and human capabilities. According to Amartya Sen's capability approach, capabilities include both the means of maintaining a livelihood and intangible elements that are necessary to achieve overall well-being. In a qualitative case study in Madagascar's Mananara-Nord and Sahamalaza Biosphere Reserves, we investigated local peoples’ conceptions of forest values.

Land Ownership and Land‐Cover Change in the Southern Appalachian Highlands and the Olympic Peninsula

Journal Articles & Books
December, 1996

Social and economic considerations are among the most important drivers of landscape change, yet few studies have addressed economic and environmental influences on landscape structure, and how land ownership may affect landscape dynamics. Watersheds in the Olympic Peninsula, Washington, and the southern Appalachian highlands of western North Carolina were studied to address two questions: (1) Does landscape pattern vary among federal, state, and private lands?
