The abandonment of farmland has become a widespread phenomenon in post-socialist countries that have seen revolutionary changes in their economic systems. The phenomenon is notable in vineyard areas, where abandonment leads to the loss of the unique character of vineyard landscapes. This paper assesses the extent of vineyard abandonment in Slovakia and analyses the driving forces behind it. We used statistical and Corine Land Cover data to map the change in vineyard areas in Slovakia and analyse the pressure of underlying driving forces.
Stakeholder perceptions of recreational and management impacts on protected coastal dune systems: A comparison of three European countries
Coastal dune systems are particularly susceptible to destabilisation through recreational pressure and because of this, conflicts frequently arise between those who want to use the dunes for recreational purposes and those who wish to see these fragile ecosystems protected. In addition, a range of approaches to resolving this conflict are being used in different countries with differing levels of success. To study this conflict, an approach based on the Q-method was applied to three European Union Member States, i.e.
spectral gradient difference based approach for land cover change detection
Change detection with remotely sensed imagery plays an important role in land cover mapping, process analysis and dynamic information services. Euclidean distance, correlation and other mathematic metrics between spectral curves have been used to calculate change magnitude in most change detection methods. However, many pseudo changes would also be detected because of inter-class spectral variance, which remains a significant challenge for operational remote sensing applications.
Greener energy: Issues and challenges for Pakistan—wind power prospective
Energy is one of the essential inputs for economic development and industrialization. A reliable supply of energy is essential to maintain and to improve human being’s living conditions. The management of energy sources, rational utilization of energy, and renewable energy source usages are vital. Among the renewable energy sources wind energy is currently viewed as one of the most significant, fastest growing, and commercially attractive source to generate electrical energy because of the mature and cost effective energy conversation technology.
Urban green commons: Insights on urban common property systems
The aim of this paper is to shed new light on urban common property systems. We deal with urban commons in relation to urban green-space management, referring to them as urban green commons. Applying a property-rights analytic perspective, we synthesize information on urban green commons from three case-study regions in Sweden, Germany, and South Africa, and elaborate on their role for biodiversity conservation in urban settings, with a focus on business sites. Cases cover both formally established types of urban green commons and bottom-up emerged community-managed habitats.
