Towards SDG 7: Mapping evidence of access to sustainable energy in L&MICs

With the slowing down of progress towards SDG 7, we move into the second phase of the 2030 agenda with more urgent questions about what interventions are effective to ensure access to affordable, reliable, sustainable and modern energy for all.

What do we know about the impacts of aquaculture?

Our systematic review finds that aquaculture interventions improve productivity and income for fish farmers in most contexts.
