Overfishing of large predatory fish populations has resulted in lasting restructurings of entire marine food webs worldwide, with serious socio-economic consequences. Fortunately, some degraded ecosystems show signs of recovery. A key challenge for ecosystem management is to anticipate the degree to which recovery is possible. By applying a statistical food-web model, using the Baltic Sea as a ...

Today water supply issue in large cities seems to be a big problem. This becomes more important with population growth and urbanization extension. To cope with this problem lots of irrigation and drainage projects have been implemented and operated that subsequently many socio- economic and cultural effects have been brought to the areas . The objective of the present study is to survey the soc...

The socio-economic situation of a country can be measured in a number of ways, often by looking at indicator values describing different aspects of the social and economic reality in the country in question. Socio-economic development can be measured and observed by comparing yearly indicator values. As a large number of indicators are often required to accurately assess the socioeconomic devel...

Land-use changes have dramatically transformed tropical landscapes. We describe an ecological-economic land-use change model as an integrated, exploratory tool used to analyze how tropical land-use change affects ecological and socio-economic functions. The model analysis seeks to determine what kind of landscape mosaic can improve the ensemble of ecosystem functioning, biodiversity, and econom...

The world's large and rapidly growing human population is exhausting Earth's natural capital at ever-faster rates, and yet appears mostly oblivious to the fact that these resources are limited. This is dangerous for our well-being and perhaps for our survival, as documented by numerous studies over many years. Why are we not moving instead toward sustainable levels of use? We argue here that th...

Rural households in Nigeria are vulnerable to shock because of their limited capacity to make informed decision on secured coping strategies which is further aggravated by some households’ specific socio-economic characteristics. Attempts were made to identify shocks being faced by households’ heads and coping strategies. Multistage sampling technique was used to select 80 respondents and well ...

For a variety of reasons it can be argued that the share of electricity generated from renewable energy sources should be increased. However, many of the new renewable energy technologies cannot yet successfully compete against conventional ones, and therefore support schemes are needed. A common approach, at least within the European Union, is the provision of guaranteed feed-in tariffs. More ...
