The cover story: During the dry season of 2015-2016, the Mekong Delta Vietnam had suffered the worst historic drought and salinity intrusion occurrence on record, causing heavy damages to nine coastal provinces (in total 13 provinces) of the Mekong Delta. Just after the drought and salinity intrusion occurred, the media and scientific community paid a lot of attention and also offered some different opinions suggesting possible solutions for the effective responses and stable development of coastal regions.
The author of the article "Historic drought and salinity intrusion in the Mekong Delta in 2016: Lessons learned and response solutions" in this issue suggests that Vietnam needs to have both short-term and long-term solutions for each specific region as well as the whole delta to ensure the sustainable development of the Mekong Delta in particular and the coastal zones in general. These solutions may include drought-salinity intrusion and flooding prevention programs, building structural and non-structural works, etc.
The cover illustrates the locations of six proposed large sluices and fresh water supply directions from the central Mekong Delta. This is a proposed long-term solution to prevent the drought and salinity intrusion in the region. Please see the article "Historic drought and salinity intrusion in the Mekong Delta in 2016: Lessons learned and response solutions" in page 20 for the story behind the cover.
