Remote sensing and GIS could be valuable tools but their application to inland fisheries and aquaculture is lagging far behind that in other sectors. Such data deficiencies can result in mistaken policies. For example, the SmartFish project12 pointed out that some African countries' food security and nutrition policies overlooked fish despite its importance in people's diets as evidenced through dedicated surveys. Moreover, the contribution of women is poorly assessed and, thus, gender-aware policies cannot be adequately formulated.
