Podría investigar cómo articular el planeamiento de los recursos hídricos con los crecientes avances en la discusión de políticas y planes por parte de organizaciones de la sociedad civil y con la la falta de continuidad, conocimientos y compromiso de las autoridades políticas con poder de decisión que se observan en los distintos niveles de las administraciones públicas de los países.
The link between trade finance and water infrastructures finance is not done enough.

What would be very interesting is to compare official geophysical methods for finding water in the underground with simple ways of divining water with sticks, water bottles etc. This should result in changes of finding water with and without the different ways of survey. As i have good results with diving it would be good to have some scientific prove.
If possible and your flavour is so, sedimentation is difficult and mostly untouched subject. It have enormous opportunity in developing countries, specially in sediment removal of reservoirs.
Dear Sir: I raise your attention to the improper management of water today; water once used is disposed to waterways. An understanding of the water balance on what water is claimed from natural water resources Vs that returned for re-use in lieu of marine pollution (on a regional basis) will help facilitate a much needed shift to a circular economy on water. With sources of marine pollution tabled against technology options to realise 'fit-for-purpose' re-use would provide a basis for a necessary shift in paradigm. Perhaps a research topic along the lines of 'A Sustainable Water Economy'... Kindly, Yuri
Balance the availability and abundance of ground water (least expensive) with the availability and abundance of surface water (usually more reliable but more expensive to produce) for your environment. It might be a short term approach for ground water with a long term approach for surface water in the future. In either case, availability and sustainability are key factors.
Why not look at one of the questions posed on this forum about a month ago (you should be able to search for it - there were some interesting responses). The question was:
"Can a dam control both flood and drought, especially for farmers?
Farmers from my community suffer from these two extremes."
