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

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.

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

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.

Long‐term declines in stream and river inorganic nitrogen (N) export correspond to forest change

Human activities have exerted a powerful influence on the biogeochemical cycles of nitrogen (N) and carbon (C) and drive changes that can be a challenge to predict given the influence of multiple environmental stressors. This study focused on understanding how land management and climate change have together influenced terrestrial N storage and watershed inorganic N export across boreal and sub‐arctic landscapes in northern Sweden.

thermodynamic approach for assessing agroecosystem sustainability

Journal Articles & Books
Décembre, 2016

By revisiting theoretical concepts in biogeography and the importance of thermodynamic laws in biosphere-atmosphere interactions, ecological sustainability in agricultural systems may be better defined. In this case study, we employed a multidisciplinary methodology for exploring agroecosystem sustainability by using eddy covariance (EC) data to compute thermodynamic entropy production (σ) and relate it to water, energy and carbon cycling in croplands and grasslands of the Central US.

Impact of pigeon pea biochar on cadmium mobility in soil and transfer rate to leafy vegetable spinach

Journal Articles & Books
Décembre, 2016

Introduction of heavy metals in the environment by various anthropogenic activities has become a potential treat to life. Among the heavy metals, cadmium (Cd) shows relatively high soil mobility and has high phyto-mammalian toxicity. Integration of soil remediation and ecosystem services, such as carbon sequestration in soils through organic amendments, may provide an attractive land management option for contaminated sites.

life and death of barn beetles: faunas from manure and stored hay inside farm buildings in northern Iceland

1. Subfossil beetle remains from archaeological sites have proven invaluable for examining past living conditions, human activities, and their impacts on landscapes and ecosystems. 2. In Iceland, specific economic practices (e.g. land management and natural resource exploitation) and major historical events (i.e. colonisation, economic intensification and commercialisation, and urbanisation) have affected local environments and left recognisable traces in the beetle subfossil record. 3.

International real estate transaction in Latvia 2011-2015: theoretical and practical aspects

Lettonie

The primary aim of this paper is to determine the most common contemporary meaning of the terms most often used to characterise international real estate transactions. The synonyms of the terms “international”, “real estate”, “transactions” or terms used in research literature with similar meanings were identified during the research.

Long‐Term Durum Wheat‐Based Cropping Systems Result in the Rapid Saturation of Soil Carbon in the Mediterranean Semi‐arid Environment

Journal Articles & Books
Décembre, 2016

Climate, soil physical–chemical characteristics, land management, and carbon (C) input from crop residues greatly affect soil organic carbon (SOC) sequestration. According to the concept of SOC saturation, the ability of SOC to increase with C input decreases as SOC increases and approaches a SOC saturation level. In a 12‐year experiment, six semi‐arid cropping systems characterized by different rates of C input to soil were compared for ability to sequester SOC, SOC saturation level, and the time necessary to reach the SOC saturation level.

Farmers are key actors in land management confronted with society’s increasing demand for public goods. Understanding farmers’ values and motivations is essential to policy makers to foster more sustainable production practices. So far, no definite value profile for European farmers exists. Based on Schwartz’s theory of basic human values, we statistically analyzed six rounds of the European Social Survey to explore farmers’ value orientations in Austria, Denmark, Finland, Germany, the Netherlands, Sweden, and Switzerland.

Runoff, nitrogen (N) and phosphorus (P) losses from purple slope cropland soil under rating fertilization in Three Gorges Region

Soil erosion along with soil particles and nutrients losses is detrimental to crop production. We carried out a 5-year (2010 to 2014) study to characterize the soil erosion and nitrogen and phosphorus losses caused by rainfall under different fertilizer application levels in order to provide a theoretical evidence for the agricultural production and coordinate land management to improve ecological environment. The experiment took place under rotation cropping, winter wheat-summer maize, on a 15° slope purple soil in Chongqing (China) within the Three Gorges Region (TGR).

Assessment of environment, land management, and spatial variables on recent changes in montado land cover in southern Portugal

Portugal

Montado decline has been reported since the end of the nineteenth century in southern Portugal and increased markedly during the 1980s. Consensual reports in the literature suggest that this decline is due to a number of factors, such as environmental constraints, forest diseases, inappropriate management, and socioeconomic issues. An assessment on the pattern of montado distribution was conducted to reveal how the extent of land management, environmental variables, and spatial factors contributed to montado area loss in southern Portugal from 1990 to 2006.
