The preparation of these guidelines began in 2008 under the supervision of Badi Besbes. Ini- tial work was undertaken by Manuel Luque Cuesta. Workneh Ayalew produced a new draft version of the guidelines, which was presented and discussed at workshops held in Argen- tina, Senegal and Italy. These workshops were attended by 100 scientists, technicians and policy-makers. A revised and updated draft was prepared by Badi Besbes, Workneh Ayalew and Dafydd Pilling. Text boxes were provided by Luis Iñiguez and Evangelina Rodero Serrano. The illustrations were prepared by Antje Weyhe. FAO would like to express its thanks to all these individuals and. | How to Feed the World in 2050 Executive Summary 1. Introduction 2. Outlook for food security towards 2050 1 The changing socio-economic environment 2 The natural resource base to 2050 - will there be enough land water and genetic diversity to meet demands 3 Potential for food security 3. Prerequisites for global food security 1 Enhancing investment in sustainable agricultural production capacity and rural development 2 Promoting technology change and productivity growth 3 Trade markets and support to farmers 4. The risks and challenges 1 Hunger amidst adequate overall supplies 2 Climate Change 3 Biofuels 5. Mobilizing political will and building institutions 2 Executive Summary By 2050 the world s population will reach billion 34 percent higher than today. Nearly all of this population increase will occur in developing countries. Urbanization will continue at an accelerated pace and about 70 percent of the world s population will be urban compared to 49 percent today . Income levels will be many multiples of what they are now. In order to feed this larger more urban and richer population food production net of food used for biofuels must increase by 70 percent. Annual cereal production will need to rise to about 3 billion tonnes from billion today and annual meat production will need to rise by over 200 million tonnes to reach 470 million tonnes. This report argues that the required increase in food production can be achieved if the necessary investment is undertaken and policies conducive to agricultural production are put in place. But increasing production is not sufficient to achieve food security. It must be complemented by policies to enhance access by fighting poverty especially in rural areas as well as effective safety net programmes. Total average annual net investment in developing country agriculture required to deliver the necessary production increases would amount to USD 83 billion. The global gap in what is required vis-à-vis current .
