Seed

Farming is a way of life for the majority in Africa. Well over 50% of Africa's population relies on farming for food and household income, if not exclusively then to a large extent. That's at least 500 million people. Pastoralists still ranch their cattle and herd their goats across great swathes of arid and semi-arid lands, but the inexorable growth in population puts ever more pressure on land resources.

But African farming, with the exception of a few large scale farms dotted across the continent, bear little relation to the kind of intensive farming practiced in much of the world. African farms are, typically, small - perhaps less than one acre of land, rainfed, cropped intensively, with a mix of cereals, root crops, legumes and vegetables, primarily for home consumption. Most farmers still use farm-saved seed – and achieve crop yields of 10-30% of full potential. Poor quality seed is not the only factor driving low crop yields: unpredictable rainfall, soil nutrient depletion, permacropping leading to increases in pathogens and pests all play their part. Outputs are low, often barely sufficient to feed the family, let alone generating income. Living on the land, eking out a living - it is a hard and ultimately unsustainable way of life.

Seed is the fundamental, the sine qua non of agriculture. We can but speculate, but in the dawn of human civilsation, Mesopotamians, Egyptian and Chinese farmers must have saved seed from their best plants. This seed was preserved, with great care, during the dry season for planting at the onset of the rains. Farming techniques were gradually improved in ancient times, into the middle ages, through crop rotation systems, basic irrigation techniques, the application of animal fertilisers, but progress was slow until two essential scientific discoveries were made. First, the microscope opened human eyes to the small world, a world which gradually revealed the infinitessimal building blocks of life. And second, Mendel's work in 19th century Germany laid the foundations for modern plant science: an understanding of germplasm, of genetic instructions, and of the potential for crop improvement. Now, little more than 100 years after the development of hybrid seed varieties, a new, post-modern, plant science of genetic transformation with possibilities beyond our comprehension is upon us.

How far we have come in our control over nature!

And yet, while the pace of development of plant science accelerates, vast areas of Africa remain in the pre-microscope and pre-Mendelian world, saving seed and relying on the natural environment for food production. Improving seed - the planting material available to farmers - is the first step in breaking the vicious circle of rural poverty. As the manager of an investment fund dedicated to expanding seed production, I am fortunate enough to be able to meet people who have the vision , the dedication, the tenacity, the determination and attention to detail to breed, produce and distribute improved seed to African farmers.

Seed is, of course, just one element of agricultural production, and the provision of improved seed will not itself transform African agriculture. It does however have the potential to begin a gradual shift from the fragmentation of land into ever smaller and less viable holdings towards the development of commercial farming. This will be a generational change, in which people migrate from the land to the city. It will require a co-ordinated plan for industrialization and urban development, and it will not happen overnight.

Seed has always been transformational. Ever since Cain's murder of Abel, the long victory of the farmer over the pastoralist has shaped human history. Africa will be no exception.
