2nd Africa Congress on Conservation Agriculture:
Supporting the Malabo Declaration and Agenda 2063
Currently, the demand from global agriculture is to increase the quantity and quality of food and agriculture production, taking care of environment, using less fossil fuel and purchased inputs, promoting biodiversity, efficiency, resilience, and climate change adaptation and mitigation.
Africa as a whole is a recent comer to the implementation of advanced technological, organizational and institutional innovations that increase the competitiveness and productivity of environmentally friendly farming systems. Led by the large-scale commercial farmers in South Africa and in other African countries, there are now several countries in Africa such as Zambia, Malawi, Mozambique, and Zimbabwe that have made strategic advances in the upscaling of smart smallholder farming.
By 2050, Africa must double food production to feed its population that is expected to increase by some 115% within the same period. However, some 98% of the current crop production in Africa is managed under the conventional tillage agriculture systems, which is known to degrade the agricultural land resources and the environment, are inefficient in terms of resource use and the delivery of ecosystem services, and contribute to global warming.
The intensive crop production of cereals, pulses and oilseeds in the large-scale commercial farming in South Africa is also associated with pastures and other fodder crops for intensive livestock production. This modern agriculture is based on what is internationally known as Conservation Agriculture (CA). CA is a No-Till System with continuous no or minimum mechanical soil disturbance, permanently covered soils (with biomass), and diversified cropping system with crops grown in rotations or associations, along with good agricultural practices of integrated crop, soil health, nutrient, water, pest, farm power, labour management, and trees and livestock where appropriate.
CA systems are known to: reduce soil erosion and degradation; improve rainwater capture and storage in the soil and increases its use efficiency; improve and maintain soil health; promote nutrient, water and carbon cycling; reduce GHG emissions and increase carbon sequestration; and allow greater and more stable farm output and factor productivity.
Science and technology development are crucial for meeting the challenge to increase production while taking care of the environment and human health. Despite the ongoing discussions by
