One of the solutions EU governments are thinking of is developing industry in African countries where people emigrate from, so people get "linked to the land" while getting a good source of income that can refrain immigration. And lately, the crops of choice are the ones that can yield biofuels.
Such is the case of the Government of the Island of Tenerife (Canary Islands, Spain), that has signed an agreement with Senegal to develop a biofuel industry. Tenerife will install a laboratory that will harvest the plants in-vitro . Then they will help the agriculture and developing a local manufacturing industry, so the fullest benefit will remain in the country. The selected crops are oil seeds to develop vegetable oil suitable for biodiesel.
Tenerife's targets are more social than ecological: developing industry in Senegal is a key factor to reduce the thousands that arrive to the Canarian shores. EU's requirements on biofuels are considered an opportunity for countries like Senegal to develop a local industry that might help in the country's economic development.
