  • This collection of papers reflects the diversity of concepts, methods, and case studies that address the challenge of Managing for Healthy Ecosystems as holistic environmental management in the context of health, integrity, and sustainability. Ecosystem health embodies the capacity of ecosystems to function without impairment, while management concerns the assessment of ecosystem conditions relative to social goals and adoption of interventions to achieve designated goals.

  • Zack feels his transportation card vibrating in his pocket, and walks carefully through the crowded bus, as it pulls into his stop. He steps out of the bus and glances up the hill, unaware of vague feelings of dissent. His house is near the top of the hill, the bus goes right past it and there is a stop half a block from his front door, but government regulations decree that every citizen must walk a minimum of ten blocks every day. Like everyone else, his transportation card is programmed to notify him to get off the bus four blocks from home; failure to comply...

  • Birds, by their very existence, enhance our daily lives. For many of us, it is a thrill to see the splash of a Brown Thrasher in a birdbath, or the flash of red in green woods as a tanager darts past. It is a gift of nature that such birds – which play an important role in healthy ecosystems by controlling pests, dispersing seeds, and pollinating plants – are also so beautiful and such a joy to watch.

  • In January 2009 WWF-UK launched its One Planet Food programme, which aims to reduce the environmental and social impacts of food consumption in the UK. We work across the food chain to reduce greenhouse gas emissions (GHGEs), protect biodiversity and reduce the impact of food on finite water resources. The aim has always been to move away from unsustainable food choices, towards sustainable ones that support global agriculture and biodiversity. Since 1960 the world’s population has doubled, increasing the demand for food and impacting on the climate and our ecosystems.

  • Critical loads, and other approaches that use models or empirical observations to link deposition with effects, provide tools that enable resource managers and policymakers to evaluate tradeoffs between the costs of more stringent emissions controls and the benefits of ecosystem services provided by healthy ecosystems. A critical loads approach can be used to synthesize scientific knowledge about air pollution thresholds that cause adverse impacts or ecosystem change.

  • Inasmuch as adenoids are tucked away up behind the palate, and are therefore out of sight, it may be well to study the picture shown above. The air passes into the lungs as shown by the arrows. At the place marked "A T" nature has provided a kind of moist cushion which helps to filter impurities out of the air. This cushion is formed of what doctors call "adenoid tissue" and is similar to that which makes up the tonsils. When this adenoid tissue grows abnormally large it forms what are known as "adenoids." From the position of these adenoids as shown on the diagram...

  • Human health can be affected by acute or chronic exposure to toxicants, through the media of water, wet land sediments, or even air when sediments becom dessicated and airborne or burnt. The nature of thes exposures is exacerbated by human behaviours and activities and they can result whenever ecosystem services have been eroded – especially when the hydrological services that maintain biological, geo logical and chemical processes have been distorted by human activities of over extraction of water.

  • If used in a way that acknowledges that humans are an intrinsic part of ecosystems, the phrase “healthy ecosystem” can be justified: humans are implicated in activities that degrade ecosystems, yet humans can also be agents for the maintenance or restora- tion of ecosystems. And the health of humans is in some way a measure of the health of the ecosystem in which they live and depend, and vice versa. ‘Health’ is also powerful metaphor for the condition of an eco- system, and ecosystem approaches to human health make critical contributions to public health.

  • The Mangalore coast which is situated at the western part of the Indian peninsula stretching to about 22 Kms of Coastal district of Dakshina Kannada, Karnataka. The healthy condition of the aquatic system depends upon its physical, chemical and biological characteristics which actually fluctuate with season and degree of pollution. Marine ecosystem is one of the richest ecosystems (Cairns & Dickson, 1971). Industrialisation, development activities in coastal zones have placed enormous stress on habitats.

  • The database community has a healthy interplay between research and development. Virtually all the people and most innovations in database systems can be traced to the research prototypes first describe in research papers. Product groups watch research proto- types with great interest, academics frequently take sabbaticals in industry, and there are many startups. These collaborations are world-wide, largely fostered by SIGMOD and the VLDB- Foundation’s international focus. The ecosystem compensates...

  • Growing awareness around the ecological impacts of water withdrawal and discharge increases both reputational and regulatory risks. Healthy aquatic ecosystems are an essential part of local communities and livelihoods, not only by serving as a source of clean drinking water, but also by providing cultural, social, aesthetic and economic value. As a result, significant water withdrawal or wastewater discharge, regardless of the extent of actual impacts on the neighboring communities or ecosystems, inevitably increase the risk of potential conflict with local communities.

  • The foundation of human health rests on healthy, stable ecosystems. Our biotic environment provides us with the fundamentals necessary for healthy lives—food, water, oxygen, warmth, light, and fuel. Earth's ecosystems also supply the raw materials for our health-care services. The global fraying of ecosystems has grave implications for our health and our ability to treat illnesses, now and in the future.
