Competition, trade, and sustainability in agriculture and food markets in Africa
探讨非洲农业与食品市场中市场集中度与气候变化应对的相互作用，聚焦东非和南部非洲的玉米、大豆及肉类饲料贸易，并提出竞争政策作为改革工具的可能性。
Abstract 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.
