Many developing countries are already affected by multiple stressors, which have increased their vulnerability to accelerated negative environmental change. Coastal erosion, deforestation and habitat fragmentation become even more serious problems in coastal locations when coupled with the projected impacts of climate change. However, anticipatory adaptation to such changes as increased coastal erosion and extreme events does not need to wait for specific climate scenarios, but is more reliant on the examination of current vulnerabilities and the range of possible no-regret strategies. These need to, however, accommodate multiple stakeholder preferences. This study therefore examines coastal communities' perceptions of environmental change in northeast Zanzibar, Tanzania and their preferences for adaptive strategies, while simultaneously examining physical change processes through change analysis. The study suggests coastal forest buffer zones as an anticipatory adaptation measure, which is based on soft measures such as vegetation planting, awareness raising and stakeholder cooperation.

Small developing islands face a number of environmental and social pressures which impact resource security. This study uses a people-centred framework to investigate social-ecological interactions for water, energy and food security. Ten semi-structured focus group discussions were conducted in Pemba and Unguja islands with village elders and leaders. Results demonstrate that shocks and stresses affecting resource security are attributed to land use and resource competition, deforestation, climate change and insufficient resource infrastructure. The scale and strength of such pressures are heightened in dry seasons and also correspond with spatial characteristics such as remoteness, intensity of land use and amount of natural resource capital. Whilst a number of adaptive responses are identified, these appear to be incremental and do not address the scale of the challenge. Maladaptive responses are also identified; most concerning is the use of poor quality water when piped water was disrupted, reduced nutritional intake during dry season and using unsustainable supplies or methods of obtaining of fuelwood. Findings illustrate the importance of using people-centred approaches for understanding the complexity of social-ecological interactions for resource security. They also demonstrate that interventions for resource management need to consider spatial heterogeneity and temporality in terms of how specific land cover uses connect to differential pressures and adaptation capacity over time.
