Developing countries can adapt to climate change effectively using nature-based solutions

Abstract

AbstractEvidence on the effectiveness of climate change adaptation interventions in low- and middle-income countries has been rapidly growing in recent years, particularly in the agricultural and coastal sectors. Here we address the question of whether results are consistent across intervention types, and risk reduction versus development-related outcomes using a systematic review of 363 empirical observations published in the scientific literature. Generally, we found more evidence of risk reduction outcomes in the coastal sector than in the agricultural sector, and more evidence of development-related outcomes in the agricultural sector. Further, results indicate that nature-based solutions have the strongest positive effects for both the coastal and agricultural sectors. Social/behavioural interventions in the coastal sector show negative effects on development-related outcomes that will need to be further tested. Taken together, our results highlight the opportunity for development and climate adaptation practitioners to promote adaptation interventions with co-benefits beyond risk reduction, particularly in the case of nature-based solutions.
