Furthermore, on 15 January 2014, the Department of Energy released the long-awaited position paper on the South African Biofuels Regulatory Framework. It announced that, by 1 October 2015, it will be mandatory for 2% of all liquid fuels in SA to be supplied by biofuels, estimated to be 393 million ℓ/ yr of bio-ethanol and 970 million ℓ/yr of biodiesel (SA Biofuels Regulatory Framework, 2014). While the Framework does take into account the implications of the policy for water use, tradeoffs between the water use and yield per hectare of different feedstock crops are not explicitly considered. Hence there is an urgent need to provide such information in order to support decision makers.
