How agricultural intensification affects the ecosystem?
How agricultural intensification affects the ecosystem?
Agricultural intensification has resulted in the loss of biodiversity and ecosystem services on farmland. conventional) and landscape characteristics on species richness of plants, ground beetles and ground-nesting farmland birds and on the biological control potential of natural enemies.
What are the negative impacts of agricultural intensification?
To the extent that intensification results in an expansion of land under production, it will generally have negative impacts on the environment owing to habitat loss, GHG emissions, and changes to local hydrology and ecosystems.
What is the effect of agricultural ecosystem?
While negative impacts are serious, and can include pollution and degradation of soil, water, and air, agriculture can also positively impact the environment, for instance by trapping greenhouse gases within crops and soils, or mitigating flood risks through the adoption of certain farming practices.
What is ecological intensification?
Ecological intensification may be formally defined as a knowledge-intensive process that requires optimal management of nature’s ecological functions and biodiversity to improve agricultural system performance, efficiency and farmers’ livelihoods.
What is agricultural intensification?
Agricultural intensification can be technically defined as an increase in agricultural production per unit of inputs (which may be labour, land, time, fertilizer, seed, feed or cash).
What is the effect of intensification?
Some activities associated with intensification, including increased use of fertilizer and other chemical inputs, are documented to have direct negative impacts on air and water quality, soil fertility, and other parts of the ecosystem.
What is meant by agriculture intensification?
Agricultural intensification can be technically defined as an increase in agricultural production per unit of inputs (which may be labour, land, time, fertilizer, seed, feed or cash). This complexity notwithstanding, there is little doubt that agricultural intensification has been a prerequisite to human civilization.
What is agricultural ecosystem?
Agricultural ecosystems are artificial ecosystems created in the process of developing land and coastal/aquatic areas for farming, animal husbandry, and fishing. There are approximately 1,210 local agricultural plant species here, over a third of which has food value. …
What are the different ecosystem services?
Four Types of Ecosystem Services
- Provisioning Services. When people are asked to identify a service provided by nature, most think of food. Fruits, vegetables, trees, fish, and livestock are available to us as direct products of ecosystems.
- Regulating Services.
- Cultural Services.
- Supporting Services.
What is the importance of studying agro ecology?
Land has become acidified, making it less fertile and causing a drop in yield. Agroecology will provide sustainable solutions to help restore soil fertility and increase the harvest again, while also preserving biodiversity.
What is the intensification?
An intensification is an increase in strength or magnitude (or intensity). Agricultural intensification is an increase of productivity per acre. The intensification of a conflict, as in a war, usually means an increase in fighting.
How does agricultural intensification contribute to soil erosion?
2. Impact of agricultural intensification on soils, including degradation by loss of soil organic matter and the release of greenhouse gases, over-application of fertilizers, erosion, soil contamination, acidification, salinization, and loss of soil genetic diversity.
