How does rotational grazing affect biodiversity?

Through grazing for a limited time period in one area, biodiversity of native plants increases because grasses have time to regrow equally without one species taking over and becoming invasive.

Why do grasslands exist?

Grasslands provide habitat to a great number of animals and native plants. These areas have been almost entirely wiped out in other countries of Europe due to modern development or intensive agriculture. In Romania, however, they still exist because of the traditional (low-impact) way of farming and seasonal grazing of livestock by shepherds.

Why is maintaining land important?

How does agriculture affect the environment?

Environment has a direct influence on existence and sustainability of agriculture as it depends upon the use of natural resources . Undoubtedly, agriculture has a greater environmental impact on Earth than any other single human activity. Conventional agricultural farming practices will not provide the food and fibre needed by burgeoning population in the future. In general, the question arises, can we develop and adopt the agriculture farming practices that can produce the food needed to feed an increasing population and simultaneously sustain our environment on long term basis. Under most systems of agricultural production at this time, it is not a question of if, but rather when, virtually all of the natural habitat on the planet will become degraded to the point that it is no longer productive and then abandoned for future generations to find ways to rehabilitate and repair. Farmers are beginning to invent, adapt and adopt a wide range of new technologies and approaches but most of them are not environment friendly. Hence, this paper reviews the linkage between environment and agriculture and the resultant impact of agriculture on environment.
