| In human dominated landscapes many diverse, and often antagonistic, human activities are intentionally and inadvertently determining the supply of various ecosystem services. Understanding how different social and ecological factors shape the availability of ecosystem services is essential for fair and effective policy and management. In this paper, we evaluate how well alternative social-ecological models of human impact on ecosystems explain patterns of 16 ecosystem services (ES) across the 62 municipalities of the Norrström drainage basin in Sweden. We test four models of human impact on ecosystems, land use, ecological modernization, ecological footprint, and location theory, and test their ability to predict both individual ES and bundles of... |

| Fisheries and aquaculture provide at least 15% of their animal protein diet to 4.3 billion persons. The rise of aquaculture dates back to the end of the 1980s, when fisheries’ production rate was beginning to decline, sounding the end of its post World War II growth phase. The volume of official landings culminated 25 years ago, without outlook for any further increase. About 60% of fish stocks are currently exploited at the maximum sustainable yield (MSY) level, most of the other ones being overexploited because of the chronic overcapacity of the fleets and of poorly regulated access to fishing. The ecosystem approach to fisheries (EAF) emerged as paradigm shift in the 1990s, underpinning the renewal of management objectives and governance along with... |

| Néhány évtizeddel ezelőtt a vidék és a mezőgazdaság fő feladata az volt, hogy elegendő mennyiségű és megfelelő minőségű élelmiszert és ipari alapanyagot állítson elő, hatékonyan foglalkoztatva a vidéki népesség jelentős hányadát. Később felmerült, hogy csökkenteni kellene az agrárium okozta környezeti terhelést, elsősorban a vegyszerfelhasználást minimalizálva. Ebből a törekvésből fejlődött ki a ma már az egész fejlett világban sikeres biotermesztés, ökológiai gazdálkodás. A század- és ezredfordulón azonban új, sokkal diverzifikáltabb igények is megjelentek; a klímaváltozást előidéző gázok kibocsátás-csökkentésétől a helyi termékek fogyasztásáig, az élelmiszer-biztonságtól a szegény országok megsegítéséig. Tanulmányunk ezekre az új kihívásokra (food miles,... |

| On the basis of ecological footprint theory, the ecological footprint and ecological carrying capacity of western China and 12 provinces and cities in 2009 are calculated. From the perspective of ecological footprint, the sustainable development status of west China and 12 provinces and cities in 2009 and 1999 are compared vertically and horizontally. Results assume that no matter weighting by using local or national ecological carrying capacity, the west area laid in the unsustainable development state in 2009; in 1999, the west area was on the unsustainable development stage taking the local and national level as the reference and it was at the sustainable stage at the global level. In 2009, most provinces in western China laid on the unsustainable stage... |

| According to the 2000-2010 Jiangsu Statistical Yearbook, per capita ecological footprint and per capita ecological carrying capacity in Jiangsu Province in the years 2001-2009 are analyzed starting from the ecological footprint model. Per capita ecological deficit is measured, as well as the pressure index of ecological footprint in order to judge the grade of ecological security and to objectively evaluate the ecological security of Jiangsu Province. GM(1,1) grey forecasting model is used to forecast the ecological security of Jiangsu Province in the years 2010-2014. Research shows that in the next 5 years, both the per capita ecological footprint and the pressure index of ecological footprint will increase by 4% and 3.7% each year, respectively. And the... |

| Quantitative estimation of the ecological footprint in Xingtai City in the years 2003-2009 is carried out by using the Ecological Footprint Model and the Time Series. Result shows that the per capita ecological footprint demand increases in Xingtai City from the year 2003 to 2009; and land use for energy shows a significant increase, accounting for the maximum proportion in per capita ecological footprint demand. Per capita ecological footprint supply gradually decreases. Ecological supply provided by cultivated land occupies the greatest proportion in the supply of per capita ecological carrying capacity, which is the main factor determining the supply of ecological carrying capacity in Xingtai City. In the years 2003-2009, ecological footprint of Xingtai... |

| Related literatures about ecological fragile is reviewed; the current status of ecological environment in the upper Min River basin is summarized. Equations for calculating the ecological footprint and ecological carrying capacity, as well as the standards of evaluating the status of ecological security are introduced. When ecological carrying capacity is greater than ecological footprint, ecosystem in this region is in safe state, and vice verse. According to the research data about five counties in upper Min River Basin, ecological footprint per capita and ecological capacity per capita are calculated in upper Min River Basin. Result shows that ecological system is in safe state in general. Interference of human activities on natural ecosystem has not... |
