We take time to higher perceive the mechanisms and unfavorable impacts of sea degree rise and saltwater intrusion on freshwater assets, soil well being, crops and our potential to play a job as a serious meals producer. are within the race towards. Developing with greatest administration practices to cut back these impacts needs to be a precedence for safeguarding meals and water safety.
