To live in good health and, in many ways, to live at all, people need a wide array of life-support benefi ts that derive from ecosystems. Collectively these are called ecosystem services , a term referring to the conditions and processes through which ecosystems, and the species that make them up, sustain and fulfi ll human life (Ehrlich and Ehrlich 1981 ; Daily 1997 ; Millennium Ecosystem Asse...
Introduction All nations face the challenge of simultaneously meeting two imperatives: developing their economies to meet the needs of their people, and ensuring that the productivity and viability of the underlying ecosystems and ecosystem services are maintained at healthy levels over time. Essentially, these imperatives are enshrined in the concept of sustainable development, which is common...
Conservation biologists, policy makers, and citizens have identified the protection of native ecosystems in low-income nations as a global social objective. Among the more popular initiatives to achieve this objective is the use of development interventions in the peripheral areas of endangered ecosystems. Such interventions indirectly provide desirable ecosystem services through two mechanisms...
Background: International policy has sought to emphasize and strengthen the link between the conservation of natural ecosystems and human development. Furthermore, international conservation organizations have broadened their objectives beyond nature-based goals to recognize the contribution of conservation interventions in sustaining ecosystem services upon which human populations are dependen...
The current unprecedented expansion of infrastructure promises to enhance human wellbeing but risks causing substantial harm to natural ecosystems and the benefits they provide for people. A framework for systematically and proactively identifying the likely benefits and costs of such developments is badly needed. Here, we develop and test at the subregional scale a recently proposed global sch...
The introduction, establishment and spread of alien species is a major threat to biodiversity and the provision of ecosystem services for human wellbeing. In order to reduce further loss of biodiversity and maintain productive and sustainable ecosystems, understanding the ecological mechanisms underlying species invasions and avoiding potentially harmful effects on native communities is urgentl...
BACKGROUND Coastal lagoons are ecosystems of major importance as they host a number of species tolerant to disturbances and they are highly productive. Therefore, these ecosystems should be protected to ensure stability and resilience. The lagoons of Amvrakikos Gulf form one of the most important lagoonal complexes in Greece. The optimal ecological status of these lagoons is crucial for the wel...
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...
Ecosystem stewardship is an action-oriented framework intended to foster the social-ecological sustainability of a rapidly changing planet. Recent developments identify three strategies that make optimal use of current understanding in an environment of inevitable uncertainty and abrupt change: reducing the magnitude of, and exposure and sensitivity to, known stresses; focusing on proactive pol...
