This chapter reflects on how men's social justice work may in future help mitigate the effects of disasters and climate-related risk by reducing gender inequalities. It presents successes of men's social justice organizations in Southern Africa in a way that suggests how these might well contribute to addressing the environmental and social challenges of reducing disaster and climate risk. The case for men's solidarity work with women to help address climate and disaster risks using a gendered lens is developed. Efforts to challenge or reorient the roles ascribed to men and the ideals associated with manhood and masculinity in Southern Africa require a significant shift in thinking and action on individual, structural and institutional levels. Disaster risk for Southern Africa is shaped primarily by exposure of this highly vulnerable population to a myriad of natural hazards, all compounded by effects of climate changes which lead to threats of increasingly frequent extreme hydro-meteorological hazard events, extreme temperatures and weather patterns.
