Mozambique to tap its large cassava ethanol potential as a tool for poverty reduction
Mozambican scientists and researchers told an International Symposium on Tropical Roots and Tubers that they are determined to develop varieties of cassava appropriate for the production of biofuels and to use the potential of a cassava industry as a tool for poverty reduction and rural development. They were speaking in Maputo on the theme 'Roots and Tubers for the production of biofuels: Challenges and Opportunities'.
The national coordinator of the Roots and Tubers Programme, Fernando Chitio, said that research is being prepared to identify varieties of cassava specifically for the production of ethanol. A cassava-based ethanol industry will be adding value to the crop and provide major opportunitites for poverty reduction amongst the country's small farmers. The International Center for Tropical Agriculture (CIAT) confirmed that a 'Green Cassava Revolution' based on the industrial use of starch offers chances for a rural renaissance throughout the tropics, where the plant is currently only grown for food (earlier post).
Likewise, the Consultative Group on International Agricultural Research (CGIAR), one of the leading global agricultural research consortia working towards strengthening the food security of people in the developing world, sees the potential:
The Mozambican scientists will be able to draw on a growing body of research aimed at kickstarting an industrial cassava sector. Some of the brightest minds in biotechnology - like Norman Borlaug, father of the Green Revolution - are working on mapping cassava's genome with the aim of improving it for fuel production (see the U.S. DOE's Joint Genome Institute and its work on cassava, as well as the work at the International Atomic Energy Agency's Plant Breeding and Genetics division, where nuclear and space breeding techniques are used to study the crop for improvement).
Cassava is 'the poor man's crop' because it grows well with modest inputs and in poor soils. When used for the production of ethanol, it offers a fuel with an excellent energy balance (more here). Other ways to add value are to utilize high quality cassava starch for the production of bioplastics and biopolymers (earlier post).
With an annual production of about six million tonnes, Mozambique is the sixth largest producer of cassava in the world. But the country has a much larger potential. It has an abundance of land on which the crop can be grown. Currently it utilizes around 1.1 million hectares of land for cassava, but according to the FAO/IIASA's Global Agro-ecological Zones database, Mozambique has a total of around 27 million hectares of highly to moderately suitable land for rainfed cassava production (map, click to enlarge).
Mozambique is seen by analysts as one of the African countries that contribute considerably to the continent's large biofuel production potential. Researchers affiliated with the International Energy Agency estimate that Mozambique can produce around 7 Exajoules of biofuels sustainably (earlier post):
energy :: sustainability :: ethanol :: biomass :: bioenergy :: biofuels :: cassava :: bioplastics :: poverty reduction :: rural development :: Mozambique ::
The country currently consumes around 590,000 tonnes of oil products per year, the bulk being diesel (IEA data). This equates to around 0.18EJ. Achieving full energy independence is well within reach, with capacity to spare to supply international markets.
When it comes to the availability of land for other crops, the country currently uses around 4.3 million hectares out of a total of 63.5 million hectares of potential arable land, or 6.6 per cent. Moreover, some 41 million hectares of poor quality land are available for the production of energy crops that require few inputs and are not suitable for food production (earlier post).
At the Tropical Roots and Tubers symposium Chitio said that as a raw material for industry, cassava would attract investment and stimulate productivity offering farmers an opportunity to sell it as a cash crop.
The executive director of the Kenya-based African Agricultural Technological Foundation (AATF), Mpoko Bokanga, said with an industrial cassava program, opportunities will be opened to reduce poverty. He also hinted at the potential for cellulosic ethanol based on the production of fuel from cassava residues (peels, stems, leaves).
"The African Continent has major potential to become a true actor in the issue of bio-fuels", Bokanga added, saying that cassava ethanol is a first stage in the cycle of development, because new bioconversion technologies will be developed over the coming decades which will increase the potenital.
Eduardo de Sousa, and Marco Patino, from Brazil, said that each country should not only determine its capacity to produce raw materials for biofuels, but should also continue using the land reserved for agriculture to produce food. In most cases, including Brazil, they claimed, there is enough land for agriculture to produce raw materials for biofuels which could boost food security:

Cassava has erupted into the first decade of the third millennium as a crop that can contribute to agro-industrial and small-farmer development in the tropics. One of the most recent advances — using cassava to produce fuel alcohol — has opened multiple opportunities, not least for small farmers.The CGIAR, in alliance with a Latin American and Caribbean Consortium to Support Cassava Research and Development (CLAYUCA) and with Dutch company Diligent Energy Systems, has begun a unique project in Colombia that explicitly aims to leverage the potential of value added cassava industries as a tool to strengthen the livelihoods of small farmers. They participate in the production of cassava as well as in pre-processing activities, within a context of decentralised biofuel production (earlier post). The example could be replicated elsewhere in developing countries.

Another important aspect is the fact that industry is the driving force to reduce hunger. As jobs are being created in service sectors to support industry, this will help people out of poverty. Small farmers may sell their cassava and generate financial resources to buy other foodstuffs and still have enough of it for their normal diet.
