Agroforestry in rice-production landscapes in Southeast Asia a practical manual Agroforestry in rice-production landscapes in Southeast Asia a practical manual Editors Prasit Wangpakapattanawong Robert Finlayson Ingrid Öborn James M. Roshetko Fergus Sinclair Kenichi Shono Simone Borelli Anique Hillbrand Michela Conigliaro This manual is intended to help rural advisory and agricultural extension workers guide farming communities in the establishment of agroforestry practices in rice-production landscapes in Southeast Asia. It sets out the steps to be taken to successfully integrate trees in rice-fields and associated farms and landscapes and presents practical tools that can be used by extensionists when supporting farmers who are implementing agroforestry practices on their farms. The ultimate aim of this guide is to support farmers in increasing the overall productivity of their farms while increasing resilience to climate change, improving the health of the surrounding environment, and enhancing the livelihoods of their communities.

With this recognition, FAO designed the Regional Rice Initiative (RRI) for Asia1 in 2013 to support countries in improving policies and strategies to promote sustainable management of rice agroecosystems. RRI, comprising regional and national components, developed pilot projects in Indonesia, Lao PDR and the Philippines. The Assessment of Trees Outside Forests in Asian Rice-production Landscapes2 project was a pilot implemented under RRI. The project aimed to evaluate the extent of trees outside forests at selected sites in the three countries and to collect information on the uses and functions of trees in rice-production landscapes. The results provided evidence that trees in rice-production landscapes can contribute to improving local socio-economic and environmental conditions. Planted or naturally regenerated trees found in homegardens, along roads and streams, in agroforestry systems, in small woodlands, along hedges and in fallows have proven to be excellent sources of goods and services to increase the socio-economic and environmental sustainability of agricultural landscapes. Trees on agricultural land can provide food and non-food products, support adaptation to climate change, increase biological diversity, regulate hydrological and nutrient cycles, protect the soil and improve nutrition and income. As a result, they can play an important role in mitigating and adapting to the multiple stressors that agricultural systems are currently facing and, consequently, in increasing food and nutrition security of rice-based farming communities. The project not only objectively demonstrated the benefits of trees outside forests in rice- production landscapes but also documented farmers’ awareness of the value of tree resources. This manual has been developed by FAO in collaboration with the World Agroforestry Centre to provide practical tools and guidelines for the implementation of agroforestry practices in rice-production landscapes in Southeast Asia. It builds on the findings of the Asian Rice-production Landscapes project and the FAO Advancing Agroforestry on the Policy Agenda: A Guide for Decision-makers3 (released in 2013) and takes advantage of ICRAF’s extensive experience with, and knowledge of, agroforestry practices. We hope that this manual will prove useful for promoting the integration of trees outside forests as part of sustainable management of these landscapes. 1 FAO, 2015c 2 FAO, 2014 3 FAO, 2013 iv Agroforestry in rice-production landscapes in Southeast Asia: a practical manual Acknowledgements The authors extend our deep appreciation to the many thousands of farmers and government officers throughout Southeast Asia for their time and knowledge provided during the many projects, consultations and field visits over more than two decades and, most recently, conducted specifically for the making of this manual in Indonesia, Lao PDR, the Philippines and Thailand. In particular, for their help in organizing visits to rice-production landscapes with agroforestry, in Indonesia we thank Riyandoko, Elok Mulyoutami, Lia Dahlia and James M. Roshetko; in the Philippines, Agustin Mercado Jr; and in Lao PDR, Natjan Chairat and Vilaphorn Visounnarath. The production of this manual has provided us with the opportunity to compile the knowledge and experience of many people over many decades not only in Southeast Asia but throughout the world. In this regard, in particular, we thank the researchers and communicators of the CGIAR Research Program on Forests, Trees and Agroforestry. v Contents Introduction: who should read this book and how to use it ..................................................... ix 1.
