Family planning, reproductive health care and gender relations could influence the future course of climate change and affect how humanity adapts to rising seas, worsening storms and severe droughts, according to The State of World Population 2009. International climate-change agreements and national policies are more likely to succeed in the long run if they take into account population dynamics, the relations between the sexes, and women\'s well-being and access to services and opportunities, the report concludes. Slower population growth, for example, would help build social resilience to climate change\'s impacts and would contribute to a reduction of greenhouse-gas emissions in the future, The State of World Population 2009 found.
