Trees for Food Security 2: Developing integrated options and accelerating scaling up of agroforestry for improved food security and resilient livelihoods in Eastern Africa

Background

The ACIAR Trees for food security project-T4FS (FSC/2012/014) continue to demonstrate the importance of trees in fields and farming landscapes for enhancing and sustaining crop yield and food security in eastern Africa. A number of promising climate smart agroforestry practices were developed, improving crop yield and in the longer term soil health, water use efficiency, carbon storage and livelihood outcomes. The capacity to reliably predict tree and crop yields across a range of soil and climate was developed within CSIRO’s APSIM model. The project revealed that farmers want greater diversity of trees on their farms than had been previously appreciated. Key adoption constraints include access to appropriate knowledge and financing options, barriers to smallholders accessing markets, availability of water resources, mechanisms to control free grazing and weak local institutions.

This second phase of agroforestry research will continue and build on the activities from T4FS and focus on tree diversity as the cornerstone of smallholder system intensification and integrate tree management with value chain development, better water management and new approaches to govern livestock management. The project aims to improve food security and smallholder livelihoods through the widespread adoption of appropriate locally adapted agroforestry practices in key agricultural landscapes in Ethiopia, Rwanda and Uganda.

The objectives are organized in form of Work Packages (WP) and led by a work package leader.

The project has five main objectives.

  1. To enhance knowledge of the impact of tree cover change on crop productivity, water, nutrients and livelihoods
  2. To integrate appropriate water management technologies and sustainable grazing options with promotion of agroforestry
  3. To establish communities of practice in the promotion of locally adaptable agroforestry options supported by appropriate inputs systems
  4. To strengthen smallholders and other market actor’s ability to participate effectively and profitably in tree product value chains
  5. To strengthen capacity of academic institutions in developing and implementing innovative agroforestry curricula

Research strategy

The T4FS project has shown how farmers are interested in a much broader range of tree species than previously appreciated and highlighted the role that trees can play in system intensification. This is shifting the emphasis of agroforestry extension efforts in the region away from concentration on a few top-down priority species, towards balanced portfolios of trees for their products that underpin sustainable commercialization in the smallholder farming sector. In response to feedback from farmers within the previous research phase, the project will integrate specific components on water management, access to credit, and value chain development to address the needs of farmers for integrated solutions rather than only promoting single components (Research in development strategy below).

Major impacts and outcomes of T4FS Phase 1:

Establishment of five rural resource Centers (2 in Rwanda, 2 Ethiopia and 1 in Uganda) and nurseries to enhance training and supply of improved tree germplasm. The RRCs have also provided business opportunities for farmer groups and unemployed youth particularly through grafted fruit trees.

Development of a vegetation and species selection map for Burundi which is integrated with the rest of VECEA map including species distribution and species selection tools; and 2 suitable tree species selection tools for Rwanda and Ethiopia.

Improved understanding of tree crop interactions in different species and contexts through establishment of four long-term tree diversity trials, more than 20 controlled on farm and on-station experiments. Over 5,000 farmers have been involved in participatory trials and associated tree planting activities.

Capacity development and strengthening through farmer training and support in MSc and PhD training and through training of national staff in development courses and skills. To enhance outreach of the project initiatives, the project maintains an extensive database in the ICRAF dataverse and the project website which is a repository of project resources and tools. Improved extension systems where training and the use of novel extension methods to promote trees on farms has been achieved.

Through the project, about 2 million tree seedlings have been provided across the project site with close monitoring of their performance by the project staff. Farmers, extension workers and policy makers understanding on the role of trees especially on- farm has also been enhanced.
