Africa faces the challenges of a growing population as well as low farm productivity. Weather changes, shorter fallow periods, deforestation, worsening farmland and the loss of young people in farming communities that move to urban areas further hinders the ability of African farms to increase farm yields.
Fortunately, many tools like drones and soil sensors are becoming more and more accessible and affordable within the continent. Especially with the African population growing at such a high rate (it’s projected to reach 2 billion people by 2050), farming in Africa needs to make use of new technologies to improve in order to prevent mass hunger in its own countries as well as in the world. Here are some examples that demonstrate how technology in Africa improves farming:
Zenvus, a precision farming startup in Nigeria, helps farmers determine appropriate fertilizers to apply to their soil as well as to optimally water their farms. The company acquires such information by measuring and analyzing soil data such as nutrients, temperature and vegetative health. The group improves farm productivity and reduces input waste for small-scale farmers.
UjuziKilimo, a big data analytics startup in Kenya, also uses precision farming to adjust irrigation needs for individual plants. While these precision farming examples demonstrate that technology in Africa indeed improves farming, Africa still requires major changes in their infrastructure in order to technologically connect the entire continent and make a large-scale soil map.
More Affordable and Effective Irrigation Methods
Sunculture sells solar-powered drip irrigation kits in Africa that make watering crops more affordable. Other efforts have also been made to increase the use of groundwater through the distribution of low-cost treadle pumps and drip-irrigation kits in Kenya, Tanzania, Zambia and other countries.
One example is portable water pumps occurs via the nonprofit organization, Kick Start. Their pumps are sold in Kenya, Tanzania and Mali from $35 to $95, and the product has been able to take 667,000 people out of poverty! For now, however, surface water is the main source of irrigation for most of Africa, so more surface water storage systems are required to optimize the numerous parts of Africa’s use of river water.
Unfortunately, some obstacles to the development of surface water storage (in some places) would be the cost of construction and possible environmental effects. The Hippo water roller, a drum that hauls large amounts of water by being rolled on the ground, helps numerous people in Africa that lack local water facilities and result in walking long distances to reach their water sources.
Improved Soil Management
Western Kenya is the perfect example of a densely populated area in Africa with low and declining soil fertility and continued threat to land resources. While also facing poverty and food security issues, such areas desperately need to conserve their natural resources, slow population growth rates and fight the HIV/AIDS pandemic.
One solution delivered by the World Agroforestry Centre was a low-cost integrated soil package that used organic manure to supplement phosphorus dressings as well as existing organic resources like biomass transfer to provide nitrogen to crops. A set of other technologies like high-quality crop seeds replenished phosphorus and nitrogen in the soil.
With the help of these technologies, farmers in Kenya increased their maize production by 2 to 3 times their typical yields!
FarmDrive connects smallholder farmers to credit and helps financial institutions increase their agricultural loan portfolios in Kenya. M-Farm in Kenya and AgroSpaces in Cameroon assist farmers to earn more by providing pricing data to prevent asymmetric price transmission.
Better Crop Storage Techniques
In 2015, the Alliance for a Green Revolution in Africa (AGRA), supported by agronomist experts from The Rockefeller Foundation, trained 2,000 farmers on various methods to reduce post-harvest loss. This made a significant impact because before the training, over 50 percent of the farmers AGRA trained either made no use of storage at all or only utilized sacks to store grain.
Some did use plastic containers, custom-made mud-walled structures, baskets and other traditional methods. However, these methods lead to 30 to 40 percent loss of their grain harvests. In comparison, AGRA’s simple storage technologies such as hermetic cocoons and bags, metal silos and polypropylene storage bags successfully kept harvested maize in good condition for six months.
Without rotten produce or pests after 12 months of storage in Tanzania, maize could be sold over longer periods of time. This enabled farmers to make more sales and thus accumulate more income and provide for improved nutrition for families and communities. So, to sustainably feed the entire growing population in Africa, such storage technologies need to be distributed and made locally.
Agricultural development is essential to eradicating poverty and to bringing food security to developing nations, so it is crucial that technology in Africa improves farming.
