Without cross-sectoral, transboundary and long-term planning, adaptation and mitigation response options in one sector can become response risks, exacerbating impacts in other sectors and causing maladaptation . For example, maintaining indigenous forest benefits biodiversity and reduces greenhouse gas emissions, but afforestation-or wrongly targeting ancient grasslands and savannas for reforestation-harms water security and biodiversity, and can increase carbon loss to fire and drought. Planned hydropower projects may increase risk as rainfall changes impact water, energy and food security, exacerbating trade- offs between users, including across countries.
