The central challenge of the 21st century is to develop economic, social, and governance systems capable of ending poverty and achieving sustainable levels of population and consumption while securing the life-support systems underpinning current and future human well-being. Essential to meeting this challenge is the incorporation of natural capital and the ecosystem services it provides into d...
The concept of nature as capital is gaining visibility in policies and practices in both the public and private sectors. This change is due to an improved ability to assess and value ecosystem services, as well as to a growing recognition of the potential of an ecosystem services approach to make tradeoffs in decision making more transparent, inform efficient use of resources, enhance resilienc...
While soil quality encompasses physical and chemical besides biological characteristics, soil health is primarily an ecological characteristic. Ecosystem health has been defined in terms of ecosystem stability and resilience in response to a disturbance or stress. We therefore, suggest that indicators for soil health could be found by monitoring responses of the soil microbial community to the ...
ABSTRACT Advances in Nuclear Magnetic Resonance (NMR) spectroscopy is a cornerstone structure elucidation of polycyclic 'cage' scaffolds. Due to the compactness these compounds, much overlap, as well unique through-space and bond NMR interactions are frequently observed. This review serves guide for future derivatives by providing some typical relevant aspects characteristic trends, substituent...
The Millennium Ecosystem Assessment (MA) scenarios address changes in ecosystem services and their implications for human well-being. Ecological changes pose special challenges for longterm thinking, because of the possibility of regime shifts that occur rapidly yet alter the availability of ecosystem services for generations. Moreover, ecological feedbacks can intensify human modification of e...
Ecotourism is growing business in Nepal due to domestic and international visitors. Specifically, natural lakes in Ramsar sites are very potential avenues for boating, scenic beauty and study the aquatic ecosystem. However Eichhornia crassipes has been threatening the beauty, ecosystem and eco-tourism business. This research was objectively carried out to explore income generation from ecotouri...
Møller and co-workers (2007) observe an “elevated frequency of abnormalities in barn swallows at Chernobyl” and “can think of no alternative explanations other than exposure to radiation that can have caused the observed patterns”. However, an obvious alternative hypothesis (e.g. Pikulik and Plenin, 1994) is that apparent impacts on birds may be due to ecosystem changes resulting from the aband...
The Millennium Ecosystem Assessment (MA) estimated that two thirds of ecosystem services on the earth have degraded or are in decline due to the unprecedented scale of human activities during recent decades. These changes will have tremendous consequences for human well-being, and offer both risks and opportunities for a wide range of stakeholders. Yet these risks and opportunities have not bee...
Sustainable Ecosystem Management (SEM) is one of the ‘four challenges’ for ecosystem services (ES) to be addressed by OpenNESS; the others relate to human well-being, competitiveness and governance. The challenge is to manage ecosystems in such a way that they can sustainably deliver an optimal combination of ecosystem services both today and into the future, with resilience to environmental an...
This article addresses the implications of rapid and uncertain ecological change, and global climate change in particular, for reserve oriented and restoration oriented ecosystem management. I argue for the following conclusions: (1) rapid and uncertain ecological change undermines traditional justifications for reserve oriented and restoration oriented ecosystem management strategies; (2) it r...
