Sustainability of Ecosystems

Ecosystems change as conditions are altered. The one thing that enables ecosystems to sustain a given composition of species over long periods of time is the dynamic balance involving all the relationships within the system. Each species in an ecosystem exists as a population. An ecosystem remains stable over a long period of time as the population of each species remains more or less constant in size and geographic distribution. This means that reproductive rates are equaled by death rates and thus a balance is achieved.

The concept of the Anthropocene may serve the purpose of focusing our minds on what we are doing to the planet. Crutzen continues, saying that To develop a world-wide accepted strategy leading to sustainability of ecosystems against human induced stresses will be one of the great future tasks of mankind (Crutzen and Stoermer, 2000).

The purpose of chemical processes is not to make chemicals The purpose is to make money. However, the profit must he made as part of a sustainable industrial activity which retains the capacity of ecosystems to support industrial activity and life. This means that process waste must be taken to its practical and economic minimum. Relying on methods of waste treatment is usually not adequate, since waste treatment processes tend not so much to solve the waste problem but simply to move it from one place to another. Sustainable industrial activity also means that energy consumption must be taken to its practical and economic minimum. Chemical processes also must not present significant short-term or long-term hazards, either to the operating personnel or to the community. 

Chemical processes will in the future need to be designed as part of a sustainable industrial development which retains the capacity of ecosystems to support industrial activity and life. This book therefore places a high emphasis on waste minimization and energy efficiency in the context of good economic performance and good health and safety practices. 

Erincipal element of sustainability. Because it is difficult to imagine owhuman health can be maintained in a degraded, unhealthy natural world, the issue of ecosystem health should be a more fundamental concern. Sustainabihty requires that the health of all diverse species as well as their interrelated ecological functions be maintained. As only one species in a complex web of ecological interactions, humans cannot separate their success from that of the total system. 

Several recent expert reviews and workshops have discussed the effects of endocrine disruption on wildlife and especially invertebrate species. These include the EU workshop on the impact of endocrine disrupters on human health and wildlife (Weybridge, 1996), the lEH workshop (Leicester, May 1997), the Environment Agency Consultative report (January 1998) and the Tyndall Forum at the Royal Institution (February 1998). They have concluded that endocrine disruption may have far-reaching adverse consequences for biodiversity and the sustainability of natural ecosystems. More comprehensive bioassay systems are required to identify and assess chemicals alleged to produce endocrine modulating effects.

Finally, careful management of ecosystems in dry lands is essential to prevent their destruction by inappropriate and uncontrolled farming and grazing. With better knowledge of the biology of the component species and of the ecosystems we will learn how they can be exploited in sustainable ways. 

Ecosystem services can be considered as being the goods and services provided by coupled ecological and social systems. They provide our material needs and quality of life, and we all depend on the sustainable use of ecosystems services. The Millennium Ecosystems Assessment has brought the continual capacity for coupled ecological-social systems to deliver eco-systems services into public attention. It states that the ability of many systems to deliver valuable services has been compromised by over-exploitation of several resources and environmental degradation. 

Chemical processes should be designed as part of a sustainable industrial activity that retains the capacity of ecosystems to support both life and industrial activity into the future. Sustainable industrial activity must meet the needs of the present, without compromising the needs of future generations. For chemical process design, this means that processes should use raw materials as efficiently as is economic and practicable, both to prevent the production of waste that can be environmentally harmful and to preserve the reserves of raw materials as much as possible. Processes should use as little energy as is economic and practicable, both to prevent the build-up of carbon dioxide in the atmosphere from burning fossil fuels and to preserve the reserves of fossil fuels. Water must also be consumed in...

Environmental contamination, either from diffuse or point sources, may compromise the ability of ecosystems to provide society with those goods and services that we require. Contamination is also linked to other widely recognised anthropogenic threats to sustainable functioning of our planet, such as the loss of biodiversity. As many soil properties and processes are conferred by soil biota, it is currently widely agreed that biological characteristics should be taken into account when evaluating the quality, or health, of soil [13, 16].

In conclusion, with respect to cultural diversity and sustainability of the agroecosystems, indigenous soil knowledge can be used as a complement to scientific knowledge. Both are fundamental to establishing strategies and practices to maintain sustainable agriculture, as well as for cultural survival and a healthy ecosystem. In addition, better biodiversity usually occurs on or adjacent to traditional ecosystems as compared to nontraditional ecosystems, and it will only be protected if the...

CLL approach and ecosystem, risk analysis. This approach provides insights on assessment and measurement endpoints for ecosystem-level EcoRA since it has a set of environmental criteria to detect the state of ecosystems critical load itself can be treated as a criterion for ecosystem sustainability (Bashkin, 2002). Moreover, one can derive spatial ecosystem risk estimates based on the percentage of ecosystems protected/potentially at risk under the current and predicted level of pollutant loads.
