Integrated conservation and development programs (ICDPs) are large, complex experiments in managing natural resources for both biodiversity and economic benefits. Monitoring should be an essential element within these programs to provide information for assessment and adaptive management; however, selecting appropriate indicators and designing effective monitoring programs is difficult due to their complexity. Useful native plants can make excellent indicator species for ICDPs because monitoring them provides information simultaneously on both ecological and socioeconomic change. In addition, monitoring useful species is necessary for establishing management plans for their sustainable use. On the Masoala Peninsula in Madagascar, site of an ICDP, we conducted household surveys and developed new ethnobotanical indices for selecting the most important plant species in different use categories from 105 forest products harvested destructively by local inhabitants. Unlike previous studies, use categories were defined non-arbitrarily as groups of substitution products (e.g., products that are equivalent in their specific usage). By comparing use and preference within groups of substitution products, it is possible to predict over-extraction of preferred species and resource switching to secondary species. Knowledge of substitution groups is thus a necessary prerequisite for selecting indicator species that will furnish early warnings of non-sustainable use. We identified 13 groups of substitution products covering the major household uses on Masoala. From these we selected the 25 species that were most heavily used or preferred. Following the use of these species over time will permit a detailed spatial and temporal analysis of changes in resource use patterns and harvesting impacts in response to the integrated conservation and development program, ultimately allowing the test of the hypothesis that economic development linked to conservation promotes conservation.

Several innovative 'participatory sensing' initiatives are under way in East Africa. They can be seen as local manifestations of the global notion of Digital Earth. The initiatives aim to amplify the voice of ordinary citizens, improve citizens' capacity to directly influence public service delivery and hold local government accountable. The popularity of these innovations is, among other things, a local reaction to the partial failure of the millennium development goals (MDGs) to deliver accurate statistics on public services in Africa. Empowered citizens, with access to standard mobile phones, can 'sense' via text messages and report failures in the delivery of local government services. The public disclosure of these reports on the web and other mass media may pressure local authorities to take remedial action. In this paper, we outline the potential and research challenges of a 'participatory sensing' platform, which we call a 'human sensor web.' Digital Africa's first priority could be to harness continent-wide and national data as well as local information resources, collected by citizens, in order to monitor, measure and forecast MDGs.
