Climate change and food systems: Linking adaptive capacity and nutritional needs of low-income households in Ghana

Climate change is projected to adversely impact the health and wellbeing of households particularly in Sub-Saharan Africa where social vulnerability is pervasive. While countries such as Ghana have intensified efforts to ensure effective and proactive adaptation to emerging climate impacts, it has also become apparent, in some instances, that levels of adaptive capacity within households and communities remain a critical determinant of the success of adaptation efforts. This is particularly the case in the poor and perennially vulnerable northern regions of Ghana where high incidence of stunting in children has highlighted the complex interlinkages that exists among climate change, food systems, household income levels, nutrition, and adaptive capacity. This is against the background that this is also the time that government and other development partners have intensified intervention actions to influence household adaptation to climate change and nutrition and health outcomes, particularly among children. Using the Karaga district of northern Ghana as a reference point, and employing the sustainable livelihoods framework, this study explores the link between household adaptive capacity to climate change and the nutritional needs of low-income households. The study finds a significant inverse relationship between household adaptive capacity and stunting in children under five years of age as an indicator of household nutritional needs. Additionally, the study also finds that agricultural practices like adopting new varieties, dry season farming, mulching, and intercropping could have positive influence on household nutrition if households have sufficient capacity to adopt such practices. The study, therefore, provides, critical insights into adaptive capacity measurement and its utility in the context of human systems. More importantly, the study also shows how carefully considered adaptation efforts can shape national policies on climate adaptation, adaptive capacity, nutrition, and health.
