农林业中的生物和遗传多样性管理问题极为复杂。本文重点介绍遗传多样性管理及其对热带地区可持续农林复合系统的影响，并分析了种间和种内多样性在农林复合系统中的作用和重要性。对热带地区传统农林系统和现代农林技术中树种内部和之间的多样性进行了评估，以便了解其中的功能要素，并评估多样性的作用和地位。评估表明，虽然农林业的做法一直是一种多样性管理和养护系统，但随着时间的推移，对农林业的研究已经不再强调多样性因素;然而，农民确实重视多样性，并从这一角度管理农林业。根据对各种传统农林业系统和研究开发的技术的分析，有充分理由在种间和种内两级增加物种和遗传多样性。审查和分析指出，需要提高认识、培训/教育、伙伴关系和协作努力，以支持农林业系统的遗传多样性;特别重要的是增加跨学科研究。
The issues of biological and genetic diversity management in agroforestry are extremely complex. This paper focuses on genetic diversity management and its implications for sustainable agroforestry systems in the tropics, and presents an analysis of the role and importance of inter- and intra-specific diversity in agroforestry. Diversity within and between tree species in traditional agroforestry systems and modern agroforestry technologies in the tropics is assessed, with a view to understanding the functional elements within them and assessing the role and place of diversity. The assessment shows that although the practice of agroforestry has been a diversity management and conservation system, research in agroforestry over time has de-emphasized the diversity element; nevertheless farmers do value diversity and do manage agroforestry from that perspective. Based on a profiling of various traditional agroforestry systems and research-developed technologies, a strong case is made for increased species- and genetic diversity, at both inter- and intra-specific levels. The review and analysis point to the need for increased awareness, training/education, partnerships and collaborative efforts in support of genetic diversity in agroforestry systems; of special importance is increased cross-disciplinary research.All the flowers of all the tomorrows are in the seeds of today – A Chinese proverb
