Households may have a mix of aquatic and land-based food production, contributing to food security and nutrition and income generation . Failures in agricultural outputs due to climate-associated factors may result in diversification to fisheries as a way of alleviating food production shortfalls; for example, fisheries landings may dramatically increase after agricultural failures following hurricanes, which can subsequently create overfishing collapses . Where climatic impact drivers affect multiple sectors, adaptation may become more difficult because of the interacting challenges . One study of 12 countries with high food insecurity levels found that fish-reliant households utilised as much land as those not reliant on fish . To meet food security requirements, most of these households needed to both farm and fish, illustrating the interdependence of aquatic- terrestrial food systems.
