magnetic investigation along a NE–SW transect of the Yasouj Plain, southwestern Iran

Journal Articles & Books
Dezembro, 2014
Irã

The magnetic susceptibility (χ) of soils varies with the slope position due to some factors such as texture, drainage class, and land use. Limited information is available about the magnetic susceptibility properties of semi arid regions of southwestern Iran. This study attempts to link χ and Fe oxides of the soils to landforms, soil characteristics, and land use (paddy and dryland soils) on the same parent materials. Ten representative pedons were taken along a NE–SW transect in different physiographic units in the Yasouj Plain.

The research on the assessment of land use changing in the case of Çeşme (İzmir) coasts

Policy Papers & Briefs
Dezembro, 2008
Turquia

The land use changes of İzmir Çeşme Coasts are determined by using remote sensing techniques in the period of 38 years. Temporal and spatial changes of land use are analyzed based on 3 land use maps which show 8 land use categories using the topographical maps and aerial photos in 1957-1976-1995. The dominancy of land use categories are calculated depending on grid map (1km x 1km). Each period of grid maps and land use maps are analyzed by spatial intersection method in GIS.

Linking Land Cover Changes in the Sub‐Alpine and Montane Belts to Changes in a Torrential River

Journal Articles & Books
Dezembro, 2016

Channel changes are the consequence of changes in sediment yield from the slopes and in the connectivity between slopes and channels because of distinct land use and climate impacts. In this study, we investigated the characteristics and evolution of a short reach in the headwater of the Ijuez River, central–southern Pyrenees. Assessment of a series of sedimentary and geomorphic structures confirmed major changes to the valley bottom, mainly related to changes in the intensity of human activity.

Efficiency indicators of farmlands use

Policy Papers & Briefs
Dezembro, 2012
Bielorrússia

The review of efficiency indicators of farmlands use was given. Their classification was analyzed and positive and negative sides of their various kinds were considered. Efficiency dependence of farmland use on value of specialization factor was investigated. Offers on perfection of system of the indicators characterizing rationality and efficiency of application of farmlands were made and also new approaches to an estimation of economic efficiency of their use were offered. The research was realized in the conditions of the Republic of Belarus.

GIS-integrated fuzzy rule-based inference system for land suitability evaluation in agricultural watersheds

Journal Articles & Books
Dezembro, 2009
Índia

Land suitability evaluation in water scarce agricultural watersheds consists of assessment of land potential for various crops as well as surface water potential to identify the scope for supplementary irrigation. A large amount of information related to the crop land suitability can be conveyed through linguistic terms. Capability of fuzzy sets in modeling involving uncertainty and vagueness is made use of in fuzzy rule-based systems, where various decision making criteria in linguistic terms are expressed as fuzzy rules.

Substantiation of the sizes of the central farmsteads of the agricultural organizations

Policy Papers & Briefs
Dezembro, 2012
Bielorrússia

In course of the research there was resulted the developed model of optimization of the sizes of land tenure of the agricultural enterprises. The research was realized in the conditions of the Republic of Belarus. As a result of realized research the optimum sizes of land tenure of the agricultural organizations with combinational organizational-industrial structure for average conditions of republic were established.

Historical legacy of the old-growth pine forest in Dividalen, northern Scandes

Journal Articles & Books
Dezembro, 2012
Suécia

The Dividalen (Sami: Dieváidvuovdi) valley in Troms county, North Norway, is well known for its old-growth pine forest, a biodiversity hotspot for dead wood-inhabiting fungi and lichens. The majority of the valley is protected within the Upper Dividalen Landscape Conservation Area and National Park. A general conception is that until the mid-nineteenth century when agriculture and forestry entered the valley, the landscape was entirely untouched by man and only used as a pathway for Sami and their reindeer herds on their annual migrations between Sweden and the Norwegian coast.

role of policies in land use/cover change since the 1970s in ecologically fragile karst areas of Southwest China: A case study on the Maotiaohe watershed

Journal Articles & Books
Dezembro, 2011
China

Study of land use/cover change and its driving forces is one of the most significant fields in global environmental change research. Karst land is a type of important and unique terrain on the Earth's surface because of its extensive distribution, impressive landforms, and high ecological fragility. Recently, more and more researchers have realized that irrational land use practices are leading to a series of alarming environmental issues including rocky desertification in karst areas.

Spatial Distribution and Temporal Change of Carbon Storage in Timber Biomass of Two Different Forest Management Units

Journal Articles & Books
Dezembro, 2007

Forests make up large ecosystems and can play an important role in mitigating the emissions of CO₂, the most important greenhouse gas. However, they are sources of atmospheric carbon when they are disturbed by human or natural causes. Storage of carbon through expansion and adaptive management of forest ecosystems can assist in reducing carbon concentrations in atmosphere.

TWENTIETH CENTURY LAND RESILIENCE IN MONTENEGRO AND CONSEQUENT HYDROLOGICAL RESPONSE

Journal Articles & Books
Dezembro, 2014
Montenegro

To study the magnitude of land degradation, desertification or resilience in Montenegro throughout the 20th and early‐21st centuries, we rephotographed the landscapes recorded on 48 historical photographs dating back to between 1890 and 1985, and analysed in a semi‐quantitative way the land use and cover changes that had occurred using an expert rating system (six correspondents). Time‐series of hydrology and population density were analysed for the period since 1948 and were compared with the changes observed using repeat photography.

Reducing Emissions from Deforestation and Forest Degradation (REDD) in Apuí, Southern Amazonas: Challenges and Caveats Related to Land Tenure and Governance in the Brazilian Amazon

Journal Articles & Books
Dezembro, 2012

Climate change mitigation mechanisms related to reducing emissions from deforestation and forest degradation (REDD) may provide significant opportunities for re-arranging political networks and overcome forest governance problems, of which land tenure is the main constraint for REDD and reforestation projects in the Amazon. We present a case study of a pilot REDD project associated with reforestation and payment for environmental services in Apuí, southern Amazonas.
