Food and agriculture accounts for around one-third of global emissions reflecting the effects of consumption in high-income countries on production and land use around the world. These effects include those transmitted through international trade such as in the constituents of animal feed for meat. African countries face a dual challenge of adapting to the growing effects of climate change in the shape of extreme weather, and increasing agriculture and food production as part of developing their economies. At the same time, there is increasing concentration in the production and trading of agriculture and food products, globally and within Africa. This article considers the interaction of concentration and responses to climate change in food markets through a focus on meat and animal feed, and the developments in maize and soybeans in East and Southern Africa. The possible role for competition policy as part of a wider reform agenda is proposed.

非洲农业和食品市场的竞争、贸易和可持续性

粮食和农业约占全球排放量的三分之一，反映了高收入国家的消费对全球生产和土地使用的影响。这些影响包括通过国际贸易传播的影响，例如肉类动物饲料的成分。非洲国家面临着双重挑战，既要适应以极端天气形式出现的气候变化日益严重的影响，又要将增加农业和粮食生产作为发展经济的一部分。与此同时，全球和非洲内部的农产品和食品生产和贸易日益集中。本文通过关注肉类和动物饲料，考虑了集中度与食品市场对气候变化的反应之间的相互作用，以及东部和南部非洲玉米和大豆的发展情况。提出了竞争政策作为更广泛改革议程的一部分的可能作用。
