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

Journal Articles & Books
Décembre, 2016
Europe

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
Décembre, 2011
Italie

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
Décembre, 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
Décembre, 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
Décembre, 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.

Different bat guilds perceive their habitat in different ways: a multiscale landscape approach for variable selection in species distribution modelling

Italie

CONTEXT: Unveiling the scale at which organisms respond to habitat features is crucial to understand how they are influenced by anthropogenic environmental changes. We implemented species distribution models (SDMs) based on multiple-scale landscape pattern analysis for four bat species representative of different foraging guilds: Nyctalus leisleri, Rhinolophus hipposideros, Myotis emarginatus and Pipistrellus pipistrellus.

Inhibition of an invasive plant (Mikania micrantha H.B.K.) by soils of three different forests in lower subtropical China

Journal Articles & Books
Décembre, 2011
Chine

Biological invasion represents one of the most serious threats to biodiversity, and invasion ecology research has become one of the central issues of contemporary environmental science. However, the relative role of soil development as correlated with succession in influencing variation in invasion resistance has seldom been examined. We hypothesized that the invasion potential of exotic plants depends on soil conditions. In this study, we explored variation among soils of three forest types in their resistance to invasion by Mikania micrantha H.B.K.

Web-based system for vineyards management, relating inventory data, vectors and images

Brésil

A Web-based system is presented, integrating spatial information from remote sensing images, GPS measurements and inventory data. Monitoring, research and management of the grape production at Rio Grande do Sul State, Brazil (624,000 metric tons in 2006) can be done through a system entirely based in open-source codes.

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

Journal Articles & Books
Décembre, 2011
Amérique septentrionale

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
Décembre, 2013
Lettonie

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

Afrique du Sud
Afrique australe

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.
