Optimisation of water pricing in the Greek agricultural sector
The agricultural sector is a dominant one in the Greek economy and thus attracts the scientific interest. Water is significant for a cultivation’s productivity and consequently for the agricultural income. Water pricing as a result has become a subject of extended study. The present study refers to the Greek agricultural economy and suggests a macroeconomic model, through which the optimisation ...

Sustainability as an evolutionary process
This paper describes a process-oriented construction of sustainability. The main argument is that sustainability is not a fixed ideal, but an evolutionary process of attempting to improve the management of systems, through improved understanding and knowledge. The process is not deterministic: the end-point is not known in advance. The starting point of the process is not some degree of ...

Impacts of voluntary agri-environmental measures on Austria's agriculture
With about 78% of farms in the Agri-Environmental Programme (AEP), Austria has one of the highest participation rates in the European Union. The programme reflects a key concern in Austrian agricultural policy, which is to reconcile agricultural production, environmental protection, social cohesion and rural development. This paper reviews the changes in agricultural policy leading up to the ...

Statistical inquiry into the causes of global temperature changes
Observed changes in average global temperatures over time have led to two general avenues of discussion in the environmental literature. The scientific community has concentrated on the statistical detection of global warming and the determination of biological and industrial factors causing average world temperatures to rise. A second avenue of thought considers the issue of economic abatement ...

Rural development programmes and strategic environmental assessment: towards a sustainable rural territory
The rural landscape and the areas of the agricultural production represent, for Italy in particular, one of the main cultural and ecological richnesses of its territory. It is, however, a complex reality in continuous growth, contaminated by a growing urban sprawl, more and more dissimilar from its bucolic idealisations and less and less coherent with the rhetoric of the environmental protection ...

Material flow accounting of rural communities: principles and outcomes in South East Asia
The paper develops a system of local Material Flow Analysis that links material flows to issues of land use transition, globalisation and food security. This system (rMFA) is then applied to villages in Vietnam, the Philippines and Laos. The rMFA shows that these villages greatly differ in terms of these indicators, and with that, in terms of risks and future-oriented policies, issues that remain ...

Bringing interregional linkages back in: industrial symbiosis, international trade and the emergence of the synthetic dyes industry in the late 19th century
Many sustainable development theorists and environmental activists often take two basic assumptions for granted. The first is that local production is generally preferable to long-distance trade. The second is that renewable sources of energy or materials are preferable to nonrenewable sources. These assumptions are, to a large extent, implicit in much of the industrial symbiosis and ...

Market efficiency and welfare effects of inter-sectoral water allocation in South Africa
The need for increased agricultural production to meet the growing demand for food, coupled with concerns for environmental sustainability, economic growth and poverty reduction has increased demand on the already scarce water in South Africa. At the same time, because of agriculture's minimal contribution, compared to the industrial and mining sectors, to South Africa's GDP and employment, the ...

Agricultural trade liberalisation and the global environment: evaluating the linkages
A reduction of trade barriers will influence the overall scale of agricultural activities, the structure of agricultural production, the mix of inputs and outputs, the production technology, and the regulatory framework. These adjustments, in turn, will influence environmental quality by increasing or reducing environmental harm and creating or destroying environmental amenities. International ...

`How will Climate Change Affect Agriculture?
Agriculture and climate change are inextricably linked—crop yield, biodiversity, and water use, as well as soil health are directly affected by a changing climate. Climate change, which is largely a result of burning fossil fuels, is already affecting the Earth’s temperature, precipitation, and hydrological cycles. Continued changes in the frequency and intensity of precipitation, ...
