Review of technology being evaluated for the forest-agriculture interface

Completed The forest-agriculture interface (FAI) is characterised by rapid changes in land use following conversion of forest to agriculture. Losses of soil organic matter and nutrients are often high just after the initial clearing, and inappropriate soil conservation practices during cropping can lead to further losses of soil fertility through leaching, erosion, and structural deterioration. Ingress of weeds after 1-2 cropping seasons may also be a major problem at some sites (eg: Brazil, Bolivia). The situation is further complicated by the fact that most forest/agriculture activities are practised by disadvantaged social groups who do not have permanent rights to land, and as such have little incentive to expend the extra effort required to develop more sustainable systems. Various technologies have been suggested to aid the transition to more stable forms of agriculture and are in the process of being tested at a number of locations. A significant amount of work funded by DFID addressing the above developmental problems by evaluating various technologies at different locations is either just completed or about to be completed. However, uptake of these technologies has so far been poor. Although this may be mostly due to inadequate dissemination pathways, there is some concern within DFID and collaborating institutions that some of the technologies may not be viable for other more fundamental reasons. There is, therefore, a clear need for a critical review of all of these technologies, reviewing not just the relevant FAI projects, but also drawing on accumulated evidence in the literature from other sites and environments, and attempting a synthesis that will suggest the direction of future research in this area. To develop and promote strategies to secure the livelihoods of poor people dependent on agricultural systems near the receding forest margin. The project identifies the conditions under which low-input techniques of intensification are likely to have a positive benefit, and therefore be taken up by farmers. Identification of the socio-economic and biophysical conditions and inputs required for success (if any) of each of the technologies, and an appraisal of where and when each technology is likely to be successful in the project areas of each focus country.Web-based searchable database containing information of socio-economic and biophysical requirements of each technology and bibliography of relevant resource material. An enhanced understanding was developed of the biophysical and socio-economic conditions required for success of techniques for stabilisation of the soil and vegetation resources of the Forest Agriculture Interface (FAI). This was achieved through a detailed analysis of the ability of the techniques to address the constraints to increased production, soil fertility maintenance and weed encroachment. Socio-economic constraints to farmers' adoption of the techniques were also covered. Cases where farmers had adopted some of the techniques were examined. Suggestions for future FAI research were made.Dissemination of the findings of the review was in the form of a 225 page review, two trip reports, and a web-based searchable database containing information on biophysical and input requirements of each technique.
