Short rotation coppice (SRC) is coppice grown as an energy crop. This woody solid biomass can be used in applications such as district heating, electric power generating stations, alone or in combination with other fuels. Currently, the leading countries in area planted for energy generation are Sweden [1] and the UK.
The system of energy forestry has faced criticism over food vs. fuel, whereby it has become financially profitable to replace food crops with energy crops. However, such energy forests do not necessarily compete with food crops for highly productive land as they can be grown on slopes, marginal, or degraded land as well – sometimes even with ...
energy crop Any crop grown exclusively as a source of fuel for the purpose of energy production. Such crops are processed into solid, liquid, or gaseous biofuels (as with bioethanol and biogas) which are then burned to generate power or heat for human purposes. ensilaging See silage. entire. Also intact.
In some instances, torrefaction of biomass may benefit the power plant if energy crops/biomass is the material the converted fossil fuel power plant will be using. [16] Also, when using energy crops as the fuel, and if implementing biochar production, the thermal power plant can even become carbon negative rather than
There are also potential impacts on biodiversity and the effects of large scale SRF on flora and fauna are not known. When planned strategically, the use of short rotation forestry can result in large environmental benefits on soil, water and local biodiversity, while having a small impact on the food production.

Continuous grazing by sheep or cattle is a widespread extensive farming system, with low inputs and outputs.. Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia.
Intensive crop farming is a modern industrialized form of crop farming.Intensive crop farming's methods include innovation in agricultural machinery, farming methods, genetic engineering technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, patent protection of genetic information, and global trade.
Agricultural expansion describes the growth of agricultural land (arable land, pastures, etc.) especially in the 20th and 21st centuries.. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy requirements due to continuing population growth (both which in turn have been attributed to agricultural expansion itself [1] [2]), with an ...
