Contribute data to the model predicting the harmful effects of drought

When talking about the Mekong Delta, people often think of a fertile and rich delta region. But the truth is that the rules of side-by-side and side-by-side no longer exist, because:
Climate change and rising sea levels cause many extreme weather phenomena, affecting people's lives.
Exploitation of water resources in the upper delta and construction of hydroelectric dams have changed the flow, reduced the amount of silt, reduced aquatic resources, and penetrated deep into the interior of the region, negatively impacting development. socio-economic of the region.
Environmental pollution, serious ecological imbalance, land subsidence, decline in groundwater level, coastal erosion, many natural forest areas.
Excessive sand and sediment exploitation, construction of houses and infrastructure close to river banks, canals and streams increase the risk of landslides.
There are many solutions proposed, including temporary and long-term purposes, however, which is the best and highly effective solution?
