Shifting cultivation, under its diverse forms of slash and burn system, is a traditional method of cultivating tropical upland soils, mostly for subsistence purposes. This traditional system of cultivation is in ecological balance with the environment and does not irreversibly degrade the soil resource, provided a sufficient length of fallow is allowed for soil restoration. However, increasing population pressures necessitate more intensive use of land. The consequence is extended cropping periods and shortened fallows.

ولعل النمو السكاني، فضلاً عن اتساع المناطق الحضرية بوتيرة سريعة، إلى جانب التنمية الاقتصادية، تسبب في إحداث ضغط غير مسبوق على المياه، لاسيما في المناطق الجافة. ويشكل الشح المتفاقم في المياه والتنافس على هذا المورد تهديداً رئيساً للتطورات المستقبلية على صعيد الأمن الغذائي والحد من وطأة الفقر، وبخاصة في المناطق الريفية.
This report aims to provide a conceptual framework to address food security under conditions of water scarcity in agriculture. It has been prepared by a team of FAO staff and consultants in the framework of the project `Coping with water scarcity: the role of agriculture?, and has been discussed at an Expert Consultation meeting organized in FAO, Rome in December 2009 on the same subject. It was subsequently edited and revised, taking account of discussions in the Expert Consultation and materials presented to the meeting.
En pocas palabras, la escasez de agua tiene lugar cuando la demanda supera el suministro de agua dulce en un área determinada. Escasez de agua = un exceso de demanda de agua para el suministro disponible Esta situación aparece como consecuencia de una elevada demanda agregada por parte de todos los sectores que consumen agua respecto al suministro disponible, bajo las condiciones de infraestructuras y las disposiciones institucionales existentes.
This paper examines some of the key technical, institutional, policy and financial responses required to achieve climate-smart agriculture which sustainably increases productivity, resilience (adaptation), reduces/removes Greenhouse Gases (mitigation), and enhances achievement of national food security and development goals. Building on case studies from the field, the paper outlines a range of practices, approaches and tools aimed at increasing the resilience and productivity of agricultural production systems, while also reducing and removing emissions.
Este documento examina algunas de las respuestas técnicas, institucionales, políticas y financieras clave y necesarias para lograr una agricultura climáticamente inteligente que incrementa de manera sostenible la productividad, la resilencia (adaptación), reduce/elimina GEI (mitigación) y fortalece los logros de metas nacionales de desarrollo y de seguridad alimentaria.
This publication summarized the activities of the project (Coping with water scarcity – the role of agriculture- Phase III: Strengthening national capacities in Lebanon). The project has helped improve the national, regional and local capacity to cope with water scarcity, as a result of an improved knowledge on how water is being used in the agricultural sector. The ultimate beneficiaries of the project were the communities of the Bekaa area, who benefited from development programme, the pilot project and interventions utilizing water for agriculture and more efficiently.
