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.

From Town to Countryside: Middle-Byzantine Bath-Houses in Eastern Crete and Their Changing Functions

Peer-reviewed publication
Septiembre, 2018
Global

The article examines the context of a recently discovered double bath-house complex in Loutres, a site near Mochlos on the north shore of eastern Crete. The excavators explore the broader questions posed by the finding, in connection to both its immediate surroundings and its wider periphery. Its relation to the site’s geography, a ravine on the shore, forms the starting point to address issues regarding its original use as well as its later transformations.

Residents’ Perception of Informal Green Space—A Case Study of Ichikawa City, Japan

Peer-reviewed publication
Septiembre, 2018
Japón
Asia

Urban green space (UGS) has been proven to be essential for improving the health of residents. Local governments thus need to provide attractive UGS to enhance residents’ wellbeing. However, cities face spatial and finanical limitations in creating and managing UGS. As a result, greening plans often fail or are postponed indefinitely. To evaluate whether informal urban green space (IGS) can supplement existing UGS, we conducted a questionnaire survey of 567 residents in Ichikawa (Japan), a city currently providing only 3.43 m2 green space per capita.

The Uneven Influence of Climate Trends and Agricultural Policies on Maize Production in the Yucatan Peninsula, Mexico

Peer-reviewed publication
Septiembre, 2018
México

Maize is an important staple crop in Mexico, and the recent intensification of climate variability, in combination with non-climatic forces, has hindered increases in production, especially for smallholder farmers. This article demonstrates the influence of these drivers on maize production trends in the three states of the Yucatan Peninsula using a mixed methods approach of climatic analysis and semi-structured interviews.

Setting and Implementing Standards for Management of Wild Tigers

Peer-reviewed publication
Septiembre, 2018
Global

Tiger numbers have collapsed so dramatically that conservationists are adopting a strategy of securing populations in priority conservation landscapes. This includes improving management effectiveness in these sites. The Conservation Assured|Tiger Standards (CA|TS) are designed to help ensure effectiveness and provide a benchmark against which to measure progress.

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.

From Contrary to Complementary Models: Central Places and Gateways in the South-Eastern Provence (Arles and Marseille)

Peer-reviewed publication
Septiembre, 2018
Francia

This paper applies the concepts of gateways and centrality, formerly opposing approaches to spatial planning, by now a powerful merged tool for archaeologists, to understand the dynamics of the evolution of cities and settlements in a long-term perspective. The samples are the two main port cities in South-Eastern Provence (France), Marseille and Arles. By means of several archaeological markers it will be shown how natural landscapes and political control influenced the fate of the economic development of both cities in Greco-Roman times.
