This paper is a re-make of Chapters 1-3 of the Interim Report World Agriculture: towards 2030/2050 (FAO, 2006). In addition, this new paper includes a Chapter 4 on production factors (land, water, yields, fertilizers). Revised and more recent data have been used as basis for the new projections, as follows: (a) updated historical data from the Food Balance Sheets 1961-2007 as of June 2010; (b) undernourishment estimates from The State of Food Insecurity in the World 2010 (SOFI) and related new parameters (CVs, minimum daily energy requirements) are used in the projections; (c) new population data and projections from the UN World Population Prospects - Revision of 2008; (d) new GDP data and projections from the World Bank; (e) a new base year of 2005/2007 (the previous edition used the base year 1999/2001); (f) updated estimates of land resources from the new evaluation of the Global Agro-ecological Zones (GAEZ) study of FAO and IIASA. Estimates of land under forest and in protected areas from the GAEZ are taken into account and excluded from the estimates of land areas suitable for crop production into which agriculture could expand in the future; (g) updated estimates of existing irrigation, renewable water resources and potentials for irrigation expansion; and (h) changes in the text as required by the new historical data and projections. Like the interim report, this re-make does not include projections for the Fisheries and Forestry sectors. Calories from fish are, however, included, in the food consumption projections, along with those from other commodities (e.g. spices) not analysed individually. The projections presented reflect the magnitudes and trajectories we estimate the major food and agriculture variables may assume in the future; they are not meant to reflect how these variables may be required to evolve in the future in order to achieve some normative objective, e.g. ensure food security for all, eliminate undernourishment or reduce it to any given desired level, or avoid food overconsumption leading to obesity and related NonCommunicable Diseases.

Recent trends in global production and utilization of bio-ethanol fuel

Production of bioethanol from lignocellulosic materials via the biochemical pathway: a review.

The world is confronted with the twin crises of fossil fuel depletion and environmental degradation. The indiscriminate extraction and consumption of fossil fuels have led to a reduction in petroleum reserves. Petroleum based fuels are obtained from limited reserves. These finite reserves are highly concentrated in certain region of the world. Therefore, those countries not having these resources are facing a foreign exchange crisis, mainly due to the import of crude petroleum oil. Hence it is necessary to look for alternative fuels, which can be produced from materials available within the country. Although vegetative oils can be fuel for diesel engines, but their high viscosities, low volatilities and poor cold flow properties have led to the investigation of its various derivatives. Among the different possible sources, fatty acid methyl esters, known as Biodiesel fuel derived from triglycerides (vegetable oil and animal fates) by transesterification with methanol, present the promising alternative substitute to diesel fuels and have received the most attention now a day. The main advantages of using Biodiesel are its renewability, better quality exhaust gas emission, its biodegradability and the organic carbon present in it is photosynthetic in origin. It does not contribute to a rise in the level of carbon dioxide in the atmosphere and consequently to the green house effect. This paper reviews the source of production and characterization of vegetable oils and their methyl ester as the substitute of the petroleum fuel and future possibilities of Biodiesel production.

Nutrition-sensitive interventions and programmes: how can they help to accelerate progress in improving maternal and child nutrition?

The rapid rise in food prices has been a burden on the poor in developing countries, who spend roughly half of their household incomes on food. This paper examines the factors behind the rapid increase in internationally traded food prices since 2002 and estimates the contribution of various factors such as the increased production of biofuels from food grains and oilseeds, the weak dollar, and the increase in food production costs due to higher energy prices. It concludes that the most important factor was the large increase in biofuels production in the U.S. and the EU. Without these increases, global wheat and maize stocks would not have declined appreciably, oilseed prices would not have tripled, and price increases due to other factors, such as droughts, would have been more moderate. Recent export bans and speculative activities would probably not have occurred because they were largely responses to rising prices. While it is difficult to compare the results of this study with those of other studies due to differences in methodologies, time periods and prices considered, many other studies have also recognized biofuels production as a major driver of food prices. The contribution of biofuels to the rise in food prices raises an important policy issue, since much of the increase was due to EU and U.S. government policies that provided incentives to biofuels production, and biofuels policies which subsidize production need to be reconsidered in light of their impact on food prices.

A Note on Rising Food Prices

The release of this year's global economic prospects finds the world economy at a crossroads. Markets all over the world are engulfed in a global economic crisis, with stock markets sharply down and volatile, almost all currencies having depreciated substantially against the dollar, and risk premiums on a wide range of debt having increased by 600 or more basis points. Commodity markets too have turned a corner. Following several years of increase, prices have plummeted, and although well above their 1990s levels, they have given up most of the increases of the past 24 months. Chapter one of this report examines the medium-term implications of this crisis for developing-country growth, inflation, and world trade. Chapter two looks at longer-term supply and demand prospects in commodity markets. It takes into account the long-term growth prospects of developing countries and their rising share in world GDP (gross domestic product), the declining quality of new pools of resources, and the influence of technology on both demand and supply. Finally, chapter three reports on the poverty impacts of high commodity prices and examines the effectiveness of policies in both producing and consuming countries in dealing with the challenges posed by periodic bouts of high commodity prices.

Modern day Malthusians warn that Malthus will ultimately be right: the world will be less and less able to feed itself as populations keep expanding and crop yields seem to have reached a peak. The authors of this volume believe that this pessimism is misplaced, and that there is in fact no worldwide food crisis. On the contrary, they show that the world food situation has improved dramatically over the past three decades: prices of agricultural commodities are at their lowest level in history in real terms and crop output is continuing to rise faster than population. This book provides a much needed and reasoned view on a subject that is too often treated emotionally. The important changes in the international food economy are considered in historical context and provide a basis for projections to 2010. The situation should continue to improve and food should become cheaper than it is today.

The World Food Outlook

Biofuels offer new opportunities for African countries. They can contribute to economic growth, employment, and rural incomes. They can become an important export for some countries and provide low-cost fuel for others. There is also a potentially large demand for biofuels to meet the rapidly growing need for local fuel. Abundant natural resources and low-cost labor make producing biofuel feedstock's a viable alternative to traditional crops; and the preferential access available to most African countries to protected markets in industrial countries provides unique export opportunities. Biofuels also bring challenges and risks, including potential land-use conflicts, environmental risks, and heightened concerns about food security. This book examines the potential of African countries to produce biofuels for export or domestic consumption and looks at the policy framework needed. It is part of the effort by the World Bank's Africa region to examine critical issues that affect the region and to recommend policies that effectively address these issues while providing an enabling environment for the private sector. The book is intended to inform policy makers and the larger development community of the global and domestic market opportunities facing biofuel producers, as well as the challenges of producing biofuels, in the Africa region.

Biofuels in Africa: Opportunities, Prospects, and Challenges

Hunger persists as a serious problem in many countries. However, this report clearly shows that the world food supply situation has been steadily improving and the prospects are good that this will continue, contrary to recent concerns. The issues of food production and poverty should be seen as ultimately separate issues. Hunger can persist amidst plenty. Hunger exists because poor people cannot buy enough food even when food prices are low. If the problems of hunger are to be overcome then the focus must be on alleviating poverty. This is an especially important time to consider the prospects for the world food situation because of major changes in the developing countries and in the former centrally planned economies of Europe and the Soviet Union. This report considers these important changes in an historical context and looking ahead to 2010. The conclusion reached is that the food situation should continue to improve for most households. This conclusion is supported by an analysis of past trends in world cereal markets as well as likely prospects for the future. The relatively optimistic outlook for the world food situation, which the report projects, should not be viewed as a reason for complacency. Continued investments in agricultural research are essential to continuing the past trends in production needed to achieve further gains in the world food situation. The report illustrates how earlier forecasts have often fallen wide off the mark. The report recognizes this and tests the robustness of its conclusion over wide ranges of basic assumptions.
