Future scenarios in agriculture Nick Vink Institute for Futures Research Department of Agricultural Economics University of Stellenbosch nv@sun.ac.za
Outline • Foresight Project Report • BFAP Outlook • Supply considerations • Demand considerations • Africa
1. The Foresight ProjectForesight. The Future of Food and Farming (2011). Final Project Report. The Government Office for Science, London
The five challenges • Balancing future demand and supply sustainably – to ensure that food supplies are affordable. • Ensuring that there is adequate stability in food supplies – and protecting the most vulnerable from the volatility that does occur. • Achieving global access to food and ending hunger. Producing enough food is not the same thing as ensuring food security for all. • Managing the contribution of the food system to the mitigation of climate change. • Maintaining biodiversity and ecosystem services while feeding the world.
Six drivers of change: Population increase • To 8bn by 2030 and >9bn by 2050 • Most in poorer countries: Africa’s population will double to two billion by 2050 • Factors affecting population size include • GDP growth • Educational attainment • Access to contraception • Gender equality • The extent of female education • Urbanisation
Six drivers of change: per capita demand for food • Some food items (such as grain-fed meat) require more resources to produce than others • Meat: increases in per capita consumption from 32 kg today to 52 kg by the middle of the century: implications for land, water and other inputs • Fish: demand is expected to increase substantially, and mostly met by aquaculture: consequences for the management of aquatic habitats and the supply of feed
Six drivers of change: governance of the food system • The globalisation of markets • The emergence and continued growth of new food superpowers: Brazil, China and India • The trend for consolidation in transnational companies in agribusiness, and food retail
Six drivers of change: governance of the food system • Production subsidies, trade restrictions and other market interventions of the rich countries • The extent to which governments act collectively to face challenges in shared resources, trade and volatility in agricultural markets. • The control of increasing areas of land for food production such as in Africa
Six drivers of change: climate change • The backdrop is rising temperatures and changing patterns of precipitation • These will affect crop growth and livestock performance and the functioning of ecosystem services • Extreme weather events will increase price volatility • Policies for climate change mitigation will also impact on the food system
Six drivers of change: competition for key resources • Land for food production: Additional land is available for food production, but in practice land will come under pressure for other uses • Land will be lost to erosion, urbanisation, recreation, desertification, salination and sea level rise • Global energy demand: Double to 2050, and the food system is vulnerable to higher energy costs • Global water demand: Agriculture currently consumes 70% of ‘blue water’ withdrawals, and demand could double by 2050.
Six drivers of change: food ethics • A major influence on politicians and policy makers and on patterns of consumption • Examples include • The acceptability of modern technology (GM) • Production methods such as organic and related management systems • The value placed on animal welfare • The relative importance of environmental sustainability and biodiversity protection • Issues of equity and fair trade
BFAP Baseline • World market: OECD-FAO Aglink Cosimo model and the FAPRI US and World Agricultural Outlook • Macroeconomic assumptions • South African supply and demand • Cooperation with industries • Farm level analyses • Building scenarios around the assumptions
Most important trends • Historically high levels of yields for maize (>4.5 t/ha) and wheat • Shift out of (white) maize and towards soybeans and sunflower • Area planted to oilseeds will reach 1.2m ha in 2020, compared to 2.2m ha for maize • Rise and rise in consumption of poultry meat: 2.2m ton/year in 2020, compared to beef (<1m ton) • SA remains a net importer of all meat • Growth in dairy to 2.6m ton in 2020: cheese fastest growing

Total and per capita agricultural production in Africa, 1964-2006
South Africa’s agricultural imports from Africa, 2008 & 2009
Wine exports to Africa • Total wine exports have declined the past 3 years • Packaged exports declined most • SA is therefore exporting more bulk wine (little value added) • BUT the market for packaged wine in Africa is growing fast
