Adaptive capacity within tropical marine protected areas - Differences between men- and women-headed households

Households within tropical coastal communities face a multitude of stressors related to environmental, social and economic change. To minimise negative impacts on households, a priority is to understand and if possible build adaptive capacity to enable adjustment to both extant, and anticipated stressors. Adaptive capacity may not be equally distributed across households due to social differences and inequalities, including gender. In this study we sought to understand whether the factors underlying adaptive capacity differ between men-and women -headed households across three marine protected areas (MPAs) in Zanzibar, Tanzania. Adaptive capacity was significantly higher in men-headed households compared to women-headed households between different MPAs as a whole, however significant differences were not found for men and women-headed households within the MPAs. The factors underlying adaptive capacity were investigated through boosted regression trees, a relatively novel approach within the field, and found to be similar between men and women counterparts. These factors were agency, material conditions, low ecosystem dependence, education, occupational multiplicity and needs satisfaction (i.e. a poverty indicator) which was singularly important in women-headed households. While the factors themselves were similar in men and women-headed households, gendered differences were found regarding differing levels in the identified factors. Accordingly, the processes that underly the differences found should be addressed within initiatives seeking to understand and build adaptive capacity.

Automated summary

This study found that the adaptive capacity of men-headed households in three marine protected areas in Zanzibar was significantly higher than that of women-headed households as a whole. However, there were no significant differences between men and women-headed households within the protected areas. The factors underlying adaptive capacity were found to be similar between men and women counterparts, but there were gendered differences in the levels of these factors.
