These elements will improve the plant and animal stock, as well as the soil. The Republic of Korea will develop technologies to prevent the erosion of highland field topsoil and expand sewage treatment facilities to protect water designated for aquaculture.
Africa
In Africa a large number of initiatives promotes sustainable soil management, as well as water and biodiversity management practices.
Namibia, as a dry location, promotes regenerative agricultural practices and microorganisms build-up to ensure soil fertility, moisture retention and carbon storing, to reverse biodiversity loss, halt bush encroachment, improve pastures and encourage restoration of the ecosystem to unlock ecosystem benefits. For a dry climate, it is commendable that some beneficial microbes have been identified in opening prospects for inoculant technology or biofertilizers which can substitute synthetic nitrogen-based fertilizers. The use of nature-based solutions which are environmentally friendly can greatly support organic farming and contribute to nutritious, safe foods. Due to high variability, these solutions/strategies need to be tailored per agro-ecology and consider environmental variations (soils, water, temperature) for adaptation.
In Algeria, initiatives have been carried out by the Trait d'Union association with a panel of farmers, and technical and research institutes, around direct seeding, in order to maintain soil moisture, sometimes avoid erosion, sequester carbon and thus limit GHG emissions.
Zambia promotes the use of efficient agroforestry and aquaculture techniques, as well as sustainable soil management, crop rotation, integrated fish farming and diversification among small-scale farmers.
Zimbabwe expands the Government of Zimbabwe-led policy action to support adoption of climate-smart and/or conservation agriculture to safeguard food security and nutrition of farmers. Conservation agriculture protects the soil and the environment through ensuring sustainable soil and water management and irrigation, in the different agro-ecological zones.
