Assessing the Sustainability of EU Timber Consumption Trends: Comparing Consumption Scenarios with a Safe Operating Space Scenario for Global and EU Timber Supply

Peer-reviewed publication
Diciembre, 2017
Global

The growing demand for wood to meet EU renewable energy targets has increasingly come under scrutiny for potentially increasing EU import dependence and inducing land use change abroad, with associated impacts on the climate and biodiversity. This article builds on research accounting for levels of primary timber consumption—e.g., toward forest footprints—and developing reference values for benchmarking sustainability—e.g., toward land use targets—in order to improve systemic monitoring of timber and forest use.

Impact of Soil Depth and Topography on the Effectiveness of Conservation Practices on Discharge and Soil Loss in the Ethiopian Highlands

Peer-reviewed publication
Diciembre, 2017
África oriental

Restoration of degraded landscapes through the implementation of soil and water conservation practices is considered a viable option to increase agricultural production by enhancing ecosystems. However, in the humid Ethiopian highlands, little information is available on the impact of conservation practices despite wide scale implementation. The objective of this research was to document the effect of conservation practices on discharge and sediment concentration and load in watersheds that have different soil depths and topography.

Multi-Criteria Decision Analysis for an Abandoned Quarry in the Evros Region (NE Greece)

Peer-reviewed publication
Junio, 2018
Global

The purpose of this study is to identify the impacts of abandoned quarries and to examine scenarios for their restoration. Two quarries were selected as case studies, which are located in the Evros Region (NE Greece). Initially, the current state of the abandoned quarries was recorded and evaluated, including slopes, landscape, land use, as well as cultural elements. Four alterative scenarios for the exploitation of each quarry were proposed, taking into account the specifics of each site. Financial, environmental, and socioeconomic criteria were then used to evaluate these scenarios.

3D Geo-Information Innovation in Europe’s Public Mapping Agencies: A Public Value Perspective

Peer-reviewed publication
Junio, 2018
Europa

Intensifying and increasingly complex physical developments under, on, and above ground, as well as the speed and accessibility of digital innovation, is resulting in growing interest in public sector investment in 3D geo-information. In Europe, a consortium of 11 public mapping agencies (PMAs) recently undertook a cost-benefit analysis for pursuing adoption of 3D geo-information.

A Minimum Cross-Entropy Approach to Disaggregate Agricultural Data at the Field Level

Peer-reviewed publication
Junio, 2018
Global

Agricultural policies have impacts on land use, the economy, and the environment and their analysis requires disaggregated data at the local level with geographical references. Thus, this study proposes a model for disaggregating agricultural data, which develops a supervised classification of satellite images by using a survey and empirical knowledge. To ensure the consistency with multiple sources of information, a minimum cross-entropy process was used. The proposed model was applied using two supervised classification algorithms and a more informative set of biophysical information.

Making Sense of Past, Present and Future. Images of Modern and Past Pastoralism among Nyangatom Herders in South Omo, Ethiopia

Peer-reviewed publication
Junio, 2018
Etiopía

This article asks how Nyangatom pastoralists currently make sense of the past, present and future of their pastoralist livelihood. Nyangatom pastoralists, like all agro-pastoralist groups in southern Ethiopia, are faced with enormous structural changes in their immediate surroundings, primarily due to large-scale industrial agriculture and a government policy encouraging them to be sedentary. While the impacts have been discussed elsewhere, thus far little focus has been placed on what images of the past, present and future these changes create among the Nyangatom.

Merging Small Scattered Pastures into Large Pasture-Forest Mosaics Can Improve Profitability in Swedish Suckler-Based Beef Production

Peer-reviewed publication
Junio, 2018
Global

A scattered structure of small pastures has negative effects on profitability in beef enterprises because small enclosures result in high labor costs per livestock unit. Moreover, larger enterprises distribute the costs across more livestock units and hence achieve lower operating costs. Creating larger coherent pastures makes it easier to increase herd size and yields positive effects due to economies of scale. This study on five Swedish organic cow-calf enterprises examined how profitability is affected by creating larger pastures from small scattered pastures and adjacent forest land.

Forest Cover Changes and Trajectories in a Typical Middle Mountain Watershed of Western Nepal

Peer-reviewed publication
Junio, 2018
Nepal

There have been drastic changes in resource use practices and land-use patterns in the middle mountains of Nepal as a result of human transformation processes of the environment. This study aimed at assessing land-use and land-cover changes, especially those related to forest cover changes, in Phewa Lake watershed—a typical middle mountain watershed of western Nepal—using multi-temporal Landsat images from 1995, 2005 and 2017.

Model Based Regional Estimates of Soil Organic Carbon Sequestration and Greenhouse Gas Mitigation Potentials from Rice Croplands in Bangladesh

Peer-reviewed publication
Septiembre, 2018
Bangladesh

Rice (Oryza sativa L.) is cultivated as a major crop in most Asian countries and its production is expected to increase to meet the demands of a growing population. This is expected to increase greenhouse gas (GHG) emissions from paddy rice ecosystems, unless mitigation measures are in place. It is therefore important to assess GHG mitigation potential whilst maintaining yield.

Firewood Collection in South Africa: Adaptive Behavior in Social-Ecological Models

Peer-reviewed publication
Septiembre, 2018
Sudáfrica
África austral

Due to the fact that the South Africa’s savanna landscapes are under changing conditions, the previously sustainable firewood collection system in rural areas has become a social-ecological factor in questions about landscape management. While the resilience of savannas in national parks such as Kruger National Park (KNP) in South Africa has been widely acknowledged in ecosystem management, the resilience of woody vegetation outside protected areas has been underappreciated.

Landscape and Hunting. The Economy of the Eschatia

Peer-reviewed publication
Septiembre, 2018
Grecia

This paper explores the place of ancient Greek hunting within the Greek landscape and environment, with particular reference to the eschatia, the marginal, uncultivated (or marginally cultivated) land. It is part of a bigger project on the social history of hunting in archaic and classical Greece, where emphasis is placed on the economic and dietary contribution of hunting for Greek communities. Hunting has attracted scholarly attention, mostly as a result of the role that hunting narratives play in Greek mythology, and the importance of hunting scenes in Greek art.
