An agroecosystem can be seen as not restricted to the immediate site of agricultural activity (e.g. the farm). That is, it includes the region that is impacted by this activity, usually by changes to the complexity of species assemblages and energy flows , as well as to the net nutrient balance .
When evaluating environmental impact, experts use two types of indicators: "means-based", which is based on the farmer's production methods, and "effect-based", which is the impact that farming methods have on the farming system or on emissions to the environment. An example of a means-based indicator would be the quality of groundwater, which ...
Old school books are full of agricultural references and examples because farming and farm animals were a familiar part of nearly every child's life. In the 1920s, 30s and 40s, as the farm population shrank and agricultural emphasis decreased in school books and educational materials, educators focused on agriculture as an occupational ...
Agroecology is defined by the OECD as "the study of the relation of agricultural crops and environment." [2] Dalgaard et al. refer to agroecology as the study of the interactions between plants, animals, humans and the environment within agricultural systems. [3]
Examples of environmental impacts of animal agriculture: Meat production is a main driver of deforestation in Venezuela; Pigs in intensive farming; Testing Australian sheep for exhaled methane production to reduce greenhouse gas emissions from agriculture; Farms often pump their animal waste directly into a large lagoon, which has environmental ...
Ex situ conservation is defined as the “conservation of components of biological diversity outside their natural habitats.” [50] Ex situ conservation is the conservation of genetic resources (species, varieties, cultivars, sub-species, landraces etc.) for food and agriculture outside their natural habitat, in a managed environment including ...
Sustainable agriculture – applied science that integrates three main goals, environmental health, economic profitability, and social and economic equity. These goals have been defined by various philosophies, policies, and practices, from the vision of farmers and consumers.
Agrominerals – minerals of importance to agriculture and horticulture, and are usually essential plant nutrients. Land degradation – process in which the value of the biophysical environment is affected by one or more combination of human-induced processes acting upon the land. Land improvement – investments making land more usable by humans.
