Will biofuels feed aeroplanes?
The prospect of using biofuels for aviation had seemed remote, with the aviation industry itself estimating that it will be dependent on fossil fuels for at least the next 30 years. Yet there are initiatives aiming to feed planes with biofuels. Air New Zealand is seeking approval for a test flight for a Boeing 747-400, using jatropha in one of the aircraft’s four engines. Jatropha is a plant that grows up to 3 metres high with berries that yield up to 40 per cent oil. The jatropha fuel is being sourced from Africa and India.
Land is being allocated for jatropha in many African countries. The usual claims that the biofuel does not compete with food production are being made. Apparently, jatropha grows on degraded land, and can tolerate poor soils with little water supply which are not suitable for food crops. In Nigeria, jatropha growing is supported by the Centre for Jatropha Promotions and Biofuels, and non-governmental organisation Green Shield of Nations is trialling jatropha crops in 11 states in the north of the country. I would like to network with communities affected by these developments and know your views on how this infrastructure will affect food sovereignty and sustainability.
