How does agriculture affect land use

image

Agriculture is often the reason for deforestation and a change in land use, from natural ecosystems that take up and store carbon dioxide (CO 2) from the atmosphere, to farmland. These activities cannot be viewed independently.

Certain agricultural land use practices, such as overgrazing, land conversion, fertilization, and the use of agricultural chemicals, can enhance the growth of invasive plants. These plants can alter fish and wildlife habitat, contribute to decreases in biodiversity, and create health risks to livestock and humans.Sep 7, 2021

How does agriculture affect the environment?

From habitat loss to pollution, agriculture contributes to many of the environmental challenges that WWF actively addresses. Agricultural expansion is a major driver of deforestation and other ecological destruction, decimating habitats and biodiversity.

What is agriculture and land use?

Agriculture and Land Use. Agricultural operations sometimes involve activities that are regulated by laws designed to protect water supplies, threatened or endangered plants and animals, or wetland areas.

How do agricultural policies affect land-use decisions?

Agricultural and conservation policies also influence land-use decisions. Land retirement programs directly affect land use, while other agricultural policies may change the economic incentives to cultivate crops.

Why is it important to manage agricultural land sustainably?

Additionally, clearing land for agricultural production is a major contributor to climate change, as the carbon stored in intact forests is released when they are cut or burned. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality.

Abstract

Human expansion throughout the world caused that agriculture is a dominant form of land management globally. Human influence on the land is accelerating because of rapid population growth and increasing food requirements.


1. Introduction

Land cover and land‐use patterns on Earth reflect the interaction of human activities and the natural environment [ 1 ]. Human population growth together with competitive land use causes land scarcity, conversion of wild lands to agriculture and other uses.


3. Results and discussion

With the growing world population the requirements are grown to cover the food demand. Human expansion throughout the world caused that agriculture is a dominant form of land management globally, and agricultural ecosystems cover nearly 40% of the terrestrial surface of the Earth.


4. Conclusion

Agriculture is a dominant form of land management globally. Rapid population growth as primary driving force connected with increasing food requirements generate great pressure on future land use, environment, natural resources, and ecosystem services.

Cross Compliance are measures which were introduced to set baseline standards that farmers must meet in order to receive funding such as the Single/Basic Payment Scheme (11). Cross Compliance applies to farmers in the UK who are receiving payment under Common Agricultural Policy (CAP) (12). There are two basic elements to cross compliance: Good Agricultural and Environmental Condition (GAEC) standards relating largely to the protection of soils, habitats and landscape features; and Statutory Management Requirements (SMR) which are either pre-existing legislative requirements or those that Member States must implement under EU law. SMRs cover environmental, public, plant and animal health and, from 2007, animal welfare objectives. A list of GAECs and SMRs is given below. In order to assess the relevance of each standard to an individual farm, click here to register for Defra’s Self-Assessment tool.
