到2050年，全球范围内的粮食产量预计需要再递增70%左右，而在发展中国家这一比例将近100%。面对粮食增产的这一需求，再加上其他领域需求的争夺，使全球许多农业生产系统纷纷置于前所未有的压力之下。这些“濒临系统”正处于愈演愈烈的水土资源大战之中，而且还经常受到不可持续的农耕方式的掣肘。因此，需要对其特别注意并采取具体的救助措施。《世界粮食和农业领域土地及水资源状况》（SOLAW）就这些高危领域如何克服制约因素并改善资源管理探讨了多种方案。在每一个领域，除了要在制度和政策上作出一些列调整外，还必须将其与扩大技术应用结合起来，以获得更好的水土资源管理效果。另外，加大投资力度、提供新型融资机制以及开展国际合作与开发援助也有助于克服这些制约因素。本书作为《世界粮食和农业领域土地及水资源状况》第一期，是对联合国粮食及农业组织出版的其他“世界状况”类报告的一个补充，其旨在揭示国家与国际层面上的论争和决策情况。

A major problem facing the areas already under cultivation, is the seriousness of soil degradation and loss of soil fertility due to indiscriminate misuse of agricultural lands, forests and grazing lands. The modern thinking assigns to soil conservation a comprehensive and more positive role than in the past. in that sustained improvement complemented by the preservation of available resources should form the central concept. Soil conservation must not be limited solely to agricultural and grazing lands.

Ainsi, pour parvenir aux rsultats souhaits, les activits d'amnagement des bassins versants doivent intgrer l'hydrologie forestire, la conservation des sols et des eaux et la planification de l'utilisation des terres dans un cadre logique plus vaste, qui tienne compte non seulement des interactions concrtes mais aussi des facteurs conomiques, sociaux et institutionnels.

This paper summarizes the good practices by nine selected OECD countries that seek to promote responsible foreign investment in developing country agriculture, primarily by investors in their territory or jurisdiction. The study provides examples of the increasing trend of home countries in establishing binding legal norms and other mechanisms as safeguards that are relevant for agricultural investment.

The rangeland resources of Pakistan constitute around 60 percent of the land area of Pakistan. This resource supports millions of livestock which are important for the livelihood food security and nutrition of poor rural people. Currently the resource is in a deteriorating condition and the current productivity is far less than its potential. Therefore, the information collected and available in this book will help in the management of rangeland resources. The book contains rangelan- related information from all the provinces/region of the country.

En el número de junio del Boletín de recursos naturales y medio ambiente nos proponemos examinar la Alianza mundial sobre los suelos, una importante entidad recientemente creada. Especialistas en suelos, personal de organizaciones internacionales, la comunidad de donantes y académicos discuten los logros que pueden derivar de esta iniciativa de colaboración.

To produce the desired results, therefore, watershed management efforts must incorporate "forest hydrology", "soil and water conservation" and "land use planning" into a broader, logical framework that takes into consideration not only physical interrelationships but economic, social and institutional factors as well. In this issue, Unasylva examines several facets of watershed management.
