negative impacts [#68]
3.1-An increase in agriculture land use to be expected in developing countries, due to population growth; increasing export options for food and feed, as well as degradation of currently cultivated land and ongoing desertification ( FAO,2003).
At the same time, demand for wood products will increase (FAO, 2000), in parallel to economic development with additional pressure on land from settlements and their infrastructure;
These aspects will lead to land use competition, bioenergy cropping versus other land uses particularly in arable and grassland

3.2- when biofuels are promoted as agricultural produce, they may compete with food and fodder crops production.

3.3- The increase in the use of agricultural raw products for fuel production could result in higher food prices, which would hit the poor in developing countries.

3.4-The environmental implications, particularly as concern deforestation and biodiversity loss, of further expansion of agriculture for the production of the feedstock crops, have to be accounted for the drawing up of the balance sheet of the pros and cons of the energy sector demands spilling over into agriculture.

3.5-The increase in biofuels cropping could result in loss of habitats, endangering rare and endemic species.

3.6- Effects in water: different feedstocks have different requirements with respect to water use and may require irrigation or the use of relatively large amount of water in situation of water scarcity.
