Energy crops
Growing crops specifically for energy production
in a sustainable
manner offers the potential for biomass to become a significant
source of renewable energy, particularly in developing countries
in Africa, Asia and South America. There are two main ways
used to produce energy crops:
1) Energy plantations, in which an area is devoted exclusively
to the production of such crops;
2) The simultaneous production of both energy and non-energy
crops, which can occur either on adjacent pieces of land (termed
'farm forestry') or on the same piece of land (termed 'agro
forestry').
Co-production of energy and non-energy crops has the benefit
of providing farmers with revenue between harvests of energy
crops, since they typically require several years of growth
before the first harvest. Another important aspect to keep
in mind is that the use of land specifically for bioenergy
causes competition with other important land uses, particularly
food production. Using the co-production approach could decrease
this problem, but also helps to meet other environmental and
socio-economic criteria for land use.
