is the principle of using the natural functionalities of an ecosystem to produce greater amounts of food, fibre, and fuel in sustainable ways. Underpinning EI is the idea that ecological functions (e.g. pollination and predator/prey relationships) can be integrated into agricultural practices, ideally leading to ‘agroecosystems’ that are sustained by natural processes and avoid many negative environmental impacts. Ecological intensification is closely related to the concepts of sustainable intensification and climate smart agriculture, but differs in its strong focus on the potential of enhancing ecological processes in food production.
The tangible and intangible benefits that are provided by ecosystems to humans, which both enable human life and that contribute to its quality. Ecosystem services include provisioning services such as food and water; regulating services such as flood and disease control; cultural services such as spiritual, recreational, and cultural benefits; and supporting services such as nutrient cycling that maintain the conditions for life on Earth.
Ecotoxicity refers to the toxicology of pollutants in the environment. The study of ecotoxicology includes consideration of the interaction of pollutants both with abiotic aspects of the environment - soil, air and water; and how they interact with living systems, at the level of cell, organ, and organism to communities and ecosystems.
is a plant or animal species that is unique to a specific geographic location, such as a country or an island. Usually the area where an endemic species live is isolated, making it difficult for the species to move to other areas. Endemic species are often uniquely adapted to the specific environment in which they live. Almost all endemic species are specialist species.
Enteric fermentation is a natural part of the digestive process of ruminant animals (e.g. cattle and sheep) where microbes decompose and ferment the food present in large rumen portion of the stomach. As a byproduct of this fermentation process, some bacteria species in the stomach produce methane.
Epidemiology is a scientific dicipline that uses data mathematical tools to understand the patterns of disease found in human populations and changes therin. It seeks to explain exactly how these patterns are caused in order to identify ways to control and treat health problems.
Eutrophication refers to the buildup of nutrients in a body of water (e.g. nitrogen and phosphorus) to a level in excess of what would occur naturally and to which aquatic ecosystems are adapted. This can result in detrimental impacts on many aquatic plants and animals, as well as the rapid overgrowth of some plants and algae.
