    The State of the World's Land and Water Resources for Food and Agriculture (SOLAW)
    Managing systems at risk
    2011
    This edition of The State of the World’s Land and Water Resources for Food and Agriculture presents objective and comprehensive information and analyses on the current state, trends and challenges facing two of the most important agricultural production factors: land and water. Land and water resources are central to agriculture and rural development, and are intrinsically linked to global challenges of food insecurity and poverty, climate change adaptation and mitigation, as well as d egradation and depletion of natural resources that affect the livelihoods of millions of rural people across the world. Current projections indicate that world population will increase from 6.9 billion people today to 9.1 billion in 2050. In addition, economic progress, notably in the emerging countries, translates into increased demand for food and diversified diets. World food demand will surge as a result, and it is projected that food production will increase by 70 percent in t he world and by 100 percent in the developing countries. Yet both land and water resources, the basis of our food production, are finite and already under heavy stress, and future agricultural production will need to be more productive and more sustainable at the same time.

    he FAO Expert Consultation on Strategies for Sustainable Animal Agriculture in Developing Countries was held at the FAO Headquarters in Rome, Italy, from 10 to 14 December 1990.Animal agriculture is a complex, multi-component, interactive process that is dependant on land, human resources and capital investment. Throughout the developing world it is practised in many different forms, in different environments and with differing degrees of intensity and biological efficiency. As a result any meaningful discussion of the subject must draw on a broad spectrum of the biological and earth sciences as well as the social, economic and political dimensions that bear so heavily on the advancement of animal agriculture. There is a growing consensus among politicians, planners and scientists alike that livestock production in the third world is not developing as it should, or at a sufficient pace to meet the high quality protein needs of a rapidly expanding human population. The sobering reality is, despite the many development projects implemented over the years by national, bilateral and multinational agencies and often substantial capital investment, there has been little or no change in the efficiency of animal production in the developing world. Livestock numbers have increased substantially in many countries and while the growth in output is welcome, it does not necessarily equate with sustainable productive growth. On the contrary it can, as it has done in the drought prone arid regions, lead to a lowering of productivity and degradation of the rangelands.The purpose of the Expert Consultation was to discuss and formulate specific criteria and questions relating to the planning and implementation of sustainable livestock production programmes in the developing world. There is increasing concern regarding the conservation of the natural resource base and protection of the global environment and FAO attaches highest priority to the sustainable development of plant and animal agriculture. This Expert Consultation is one of a number of initiatives being undertaken by FAO to ensure the sustainability of it's agricultural development programme. The discussion and recommendations arising from this Expert Consultation have been used to help to focus and guide global, regional and national policies and action programmes on the sustainable development of agriculture and have provided an important contribution to the FAO/Government of the Netherlands International Conference on Agriculture and the Environment held in the hague, 15–19 April, 1991.
