Eucalypts in Agroforestry, Reforestation, and Smallholders’ Conceptions of “Nativeness”: A Multiple Case Study of Plantation Owners in Eastern Paraguay

Journal Articles & Books
Dezembro, 2015
Paraguai

Despite claims that plantations both enhance and undermine the quality, valuation and protection of natural forests, plantation forestry continues to expand worldwide. In Paraguay, changes in environmental policy, extension practices, and public perception of eucalypts (Eucalyptus spp.) have promoted a boom in plantation production of these species over the last 20 years.

PROBLEMS AND CLASSIFICATION OF FORMER MILITARY AREAS

Journal Articles & Books

Rússia

Integration of the Russian Federation in the international community, to find the most effective ways to implement the military and land reforms require a comprehensive study. The paper identifies the main problems that hinder the effective implementation of the reform of the conversion, the ways of their solutions, including use of the experience of the advanced countries of the European Union. Identified military objects to be conversion, shown combining them into groups according to various criteria. Proposed a typology of ex-military territories.

Landscape indicators of stream water quality in central Appalachia (USA): Land use/land cover or land surface condition?

Journal Articles & Books
Dezembro, 2013
Estados Unidos

Relationships between land use/cover (LUC) and stream water quality have been well-documented in many environments and at a range of spatial scales. From these analyses, reduced in-stream biological integrity and habitat quality are commonly associated with increasing amounts of anthropogenic LUC. However, very few studies have examined the influence of landscape condition, relative to studies using LUC, on water quality parameters. Landscape condition indices use remote sensing-based data to quantify biophysical land surface condition.

Land management as a factor controlling dissolved organic carbon release from upland peat soils 1: Spatial variation in DOC productivity

Journal Articles & Books
Dezembro, 2009

The importance of soil storage in global carbon cycling is well recognised and factors leading to increased losses from this pool may act as a positive feedback mechanism in global warming. Upland peat soils are usually assumed to serve as carbon sinks, there is however increasing evidence of carbon loss from upland peat soils, and DOC concentrations in UK rivers have increased markedly over the past three decades.

Nature reserves as catalysts for landscape change

Journal Articles & Books
Dezembro, 2012

Scientists have called repeatedly for a broader conservation agenda that emphasizes not only protected areas but also the landscapes in which those areas are embedded. We describe key advances in the science and practice of engaging private landowners in biodiversity conservation and propose a conceptual model for integrating conservation management on reserves and privately owned lands. The overall goal of our model is to blur the distinction between land management on reserves and the surrounding landscapes in a way that fosters widespread implementation of conservation practices.

Monitoring changes in pastoral resources in eastern Sudan: A synthesis of remote sensing and local knowledge

Journal Articles & Books
Dezembro, 2013
Sudão

The pastoral resources in eastern Sudan are changing under the combined impact of increasing anthropogenic activities such as clearance of natural vegetation and the effect of state policies that favour crop farming against pastoralism. Remotely sensed data are used to detect spatial and temporal changes from 1979 to 2009 in the land use/land cover (LULC) across three study sites. Areas of natural vegetation have been reduced from 26.1% in 1979 to 12.6% in 1999 and further to 9.4% in 2007. The majority of this reduction went into agricultural land.

Rangeland responses to pastoralists’ grazing management on a Tibetan steppe grassland, Qinghai Province, China

Dezembro, 2016
China
Ásia

Livestock grazing is the principal land use in arid central Asia, and range degradation is considered a serious problem within much of the high-elevation region of western China termed the Qinghai-Tibetan Plateau (QTP). Rangeland degradation on the QTP is variously attributed to poor livestock management, historical-cultural factors, changing land tenure arrangements or socioeconomic systems, climate change, and damage from small mammals. Few studies have examined currently managed pastures using detailed data capable of isolating fine-scale livestock–vegetation interactions.

Climate and vegetation hierarchically structure patterns of songbird distribution in the Canadian boreal region

Journal Articles & Books
Dezembro, 2014

Environmental factors controlling the distribution and abundance of boreal avifauna are not fully understood, limiting our ability to predict the consequences of a changing climate and industrial development activities underway. We used a compilation of avian point‐count data, collected over 1990–2008 from nearly 36 000 locations, to model the abundance of individual forest songbird species within the Canadian boreal forest.

Agricultural land-use change and its drivers in mountain landscapes: A case study in the Pyrenees

Journal Articles & Books
Dezembro, 2006
França

Research studies aimed at integrating socio-economic and geo-bio-physical factors are increasingly being used in order to improve our understanding of the causes and effects of land-use change and to support sustainable landscape development. In line with such approaches, the study reported in this paper addresses land-use change and its drivers in the peripheral area of the Pyrenees National Park (PNP), France. The focus is land-use change on private farmland currently utilised by the farmers.

Attitudes, knowledge and practices affecting the Critically Endangered Mariana crow Corvus kubaryi and its conservation on Rota, Mariana Islands

Journal Articles & Books
Dezembro, 2015

The population of the Critically Endangered Mariana crow Corvus kubaryi on the island of Rota, Commonwealth of the Northern Marianas Islands, has decreased dramatically in recent years. It is unclear to what extent negative practices by people, such as inappropriate land use or persecution of crows, have contributed to this decline. We conducted a public opinion survey to document ongoing practices towards the crows on Rota, to assess residents’ knowledge of and attitudes towards the birds, and to gauge potential responses to a government-instituted land incentive programme.

integrated approach to environmental quality assessment in a coastal setting in Campania (Southern Italy)

Journal Articles & Books
Dezembro, 2013
Itália

The coastal region of Southern Italy’s Caserta province, known as the Litorale Domitio (Domitia coast) has been subjected to increasing pressure from unsustainably fast economic and urban growth in the last century, that resulted in a induced serious land degradation. To obtain a comprehensive picture of the ecological status of the Domitia coastal zone (Campania, Southern Italy), a holistic methodology has been applied. Sedimentological, geochemical, and biological analyses of the surface sediments and water samples were performed along the submerged beach.
