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?

Maintaining land for agricultural use can also prevent that land from being developed and urbanized, in areas where native species have difficulty finding original habitat. The United States Department of Agriculture Farm Service Agency (FSA) created seven voluntary land conservation programs for this purpose.

Land Use

For much of human history, most of the world’s land was wilderness: forests, grasslands and shrubbery dominated its landscapes. Over the last few centuries, this has changed dramatically: wild habitats have been squeezed out by turning it into agricultural land.


CO 2 and Greenhouse Gas Emissions

When it comes to tackling climate change, the focus tends to be on ‘clean energy’ solutions – the deployment of renewable or nuclear energy; improvements in energy efficiency; or transition to low-carbon transport.


Water Use

How do the water footprints of different food products compare? Which foods used the most and least freshwater in their production?


Eutrophication

Eutrophication – the pollution of water bodies and ecosystems with excess nutrients – is a major environmental problem. The runoff of nitrogen and other nutrients from agricultural production systems is a leading contributor.


Food miles

People often think that eating ‘local’ – buying foods which are produced close to home – is one of the most effective ways to reduce our carbon footprint.


Food waste

Food production accounts for around one-quarter – 26% – of global greenhouse gas emissions. 43 This is a lot, but it’s slightly easier to digest when we remind ourselves that food is a basic human need.
