Climate Change: Environmental stress negatively impacts women in climate hotspots



今回、Nitya Raoたちの研究グループは、アフリカとアジアの農業生態学的に異なる3つの地域(半乾燥地域、山岳地帯、氷河から溶けた水が流れ込んでいる河川地帯と三角州)における合計数千世帯を対象とした25の事例研究において、女性の行為主体性が適応応答にどのように寄与したのかを評価した。その結果、大多数の事例で、男性季節労働者と女性の劣悪な労働条件が、制度上の欠陥又は貧困と組み合わさって、環境ストレス条件下の女性の戦略的意思決定能力を制約していることが見いだされた。また、Raoたちは、女性の活動が世帯構造や社会規範によって支持されている場合であっても、環境ストレスが女性に悪影響を及ぼすことを明らかにした。


Environmental stress negatively affects women’s agency - the ability to make meaningful choices and strategic decisions - in climate hotspots in Africa and Asia, suggests a paper published in Nature Climate Change. Such stressors can lead to household adaptation strategies that increase the responsibilities and burdens women face.

Entrenched social structures, reinforced at household, community and state level, shape men and women’s individual experiences and reactions to climate change. Examining gender within this context highlights how sustainable, equal and effective adaptation is critical in places where climatic shifts, social structures and livelihood-sensitivity restricts mobility, access to resources and division of work.

Nitya Rao and colleagues assessed how women’s agency contributes to adaptation responses in 25 case studies - collectively including thousands of households from Africa and Asia - across three distinct agro-ecological regions: semi-arid, mountain and glacier-fed river basins and deltas. The authors found that, across the majority of cases, male migration for work and women’s poor working conditions combine with either institutional failure or poverty to constrain women’s ability to make strategic decisions under conditions of environmental stress. The authors also identify that even when household structures and societal norms are supportive of women’s agency, environmental stress still impacts them negatively.

By identifying common conditions that depress women’s agency across different contexts, this study suggests that working conditions for women and migrant men, and poor material conditions, are key barriers that could be addressed to strengthen the ability to adapt to climate change.
