Enzyme activities and compositional shifts in the community structure of bacterial groups in English wetland soils associated with preservation of organic remains in archaeological sites

Journal Articles & Books
Diciembre, 2011

To extend our previous research on preservation in situ of organic archaeological remains in wetland soils, physicochemical variables and extracellular enzyme activities (β-d-glucosidase, phosphatase, and leucine aminopeptidase) were measured in two archaeological wetland soils in northern England, from the soil surface down to 100 cm during two years. These two locations, with a proven potential to contain and preserve archaeo-environmental remains, were of interest because they had different hydrological and land-management history.

Assessment of the cover changes and the soil loss potential in European forestland: First approach to derive indicators to capture the ecological impacts on soil-related forest ecosystems

Europa

The Member States of the European Union have committed to the maintenance and protection of forest lands. More precisely, the Member States aim to ensure the sustainable development and management of the EU's forests. For 2013, Eurostat's statistics about primary and secondary wood products in the European forest land (65% thereof privately owned) estimate a roundwood production of 435 millionm3 in total. Harmonised information, i.e., spatially and temporarily differentiated, on forestry and wood harvesting activities in the European forests are missing however.

Phytoremediation of contaminated sediments: evaluation of agronomic properties and risk assessment

Journal Articles & Books
Diciembre, 2011
Italia

This study evaluates the possibility of reusing marine sediments in land management. The sediments, dredged from Livorno port (Italy), had previously been phytotreated, using a salt-tolerant plant cover and earthworms, with the aim of reducing the salt level and improving the texture and microbiology. In this study, sediments were investigated in order to: (1) test their capability to be used as a revitalised soil-like substrate (techno-soil), and (2) assess the human exposure risks associated with sediment management.

Effects of cropping systems and irrigation on the bio-agronomic and quality rsponse of industrial tomato (Lycopersicon esculentum Mill.)

Journal Articles & Books
Diciembre, 2012

This paper shows the results obtained in 2009 of a study carried out by the Dipartimento di Agronomia Ambientale e Territoriale (D.A.A.T.) aimed at identifying and evaluating various low input cropping systems for industrial tomato varieties, a traditional farming crop in Sicily. The tests were carried out on the Sparacia experimental farm (Cammarata AG, 37°37’N, 13°42’E). The farm is located in a sub-arid area with average rainfall levels of approx. 500 mm and average min/max temperatures of 9 and 21°C. The soils, typical of soil types in the area, are Eutric Vertisols.

Variations in the Social Networks of Forest Owners: The Effect of Management Activity, Resource Professionals, and Ownership Size

Journal Articles & Books
Diciembre, 2014

Social networks play an important role in the communication of information among forest owners and how owners process that information in making land management decisions. This article examines variations in the social network characteristics of family forest owners using survey data and interviews with 42 owners in south-central Indiana. We examine how network structure and content vary by harvesting activity, information sources, ownership attributes, sociodemographic characteristics, and location.

Cattle as ecosystem engineers: New grazing management enhances rangeland biodiversity

Journal Articles & Books
Diciembre, 2014

A confluence of factors has shaped the composition and structure of vegetation on rangelands in the American West. These factors include climate, soils, topography, history of grazing and fire (both wildfire and prescribed fire) as well as legacy effects from prior land management practices. Despite the inherent differences in vegetation of rangelands resulting from these factors, sustainable management practices involving matching forage availability to forage demand have resulted in managing large acreages in a similar fashion for livestock production.

Increased rainfall variability reduces biomass and forage quality of temperate grassland largely independent of mowing frequency

Journal Articles & Books
Diciembre, 2012

Climate models indicate that global warming will stimulate atmospheric exchange processes and increase rainfall variability, leading to longer dry periods and more intense rainfall events. Recent studies suggest that both the magnitude of the rainfall events and their frequency may be as important for temperate grassland productivity as the annual sum. However, until now interactive effects between land management practice, such as mowing frequency, and rainfall variability on productivity and forage quality have not been studied in detail.

potential of land conservation agreements for protection of water resources

Journal Articles & Books
Diciembre, 2012

A survey of landowners assessed the feasibility of long-term land conservation agreements for water resource protection. Such a private conservation tool is yet to be established in the UK, but innovation by an environmental charity seeks to mitigate the impacts of diffuse pollution from agriculture on water quality. Under the agreements a one-off payment would be made for agreed restrictions on use of targeted areas of farmland.

Long-term avian research at the San Joaquin Experimental Range: Recommendations for monitoring and managing oak woodlands

Journal Articles & Books
Diciembre, 2011
América Septentrional

Experimental forests and ranges are living laboratories that provide opportunities for conducting scientific research and transferring research results to partners and stakeholders. They are invaluable for their long-term data and capacity to foster collaborative, interdisciplinary research. The San Joaquin Experimental Range (SJER) was established to develop appropriate land management practices on foothill rangelands in California. SJER has a long and rich history of avian research.

Research in geodesy and land management at the Latvia University of Agriculture

Conference Papers & Reports
Diciembre, 2013
Letonia

The paper gives an overview of the directions and results of research carried out in geodesy and land management at the Latvia University of Agriculture from the year 1939, when the Surveying Department (later the Department of Geodesy) was established, up to the present day. Since the beginnings of the Department, researches in geodesy have been associated with problems of precise levelling: vertical movements of the earth crust, deformation of buildings and structures, as well as accuracy evaluation of geodetic instruments.

Mapping ecosystem services for planning and management

Sudáfrica
África austral

This study mapped the production of five ecosystem services in South Africa: surface water supply, water flow regulation, soil accumulation, soil retention, and carbon storage. The relationship and spatial congruence between services were assessed. The congruence between primary production and these five services was tested to evaluate its value as a surrogate or proxy ecosystem service measure.
