Florida is surrounded by water, so estimates that sea ranges will rise by a foot—and much more in some areas, together with Tampa Bay—by 2050 is dangerous information. That estimate comes from a brand new report launched by the Nationwide Oceanic and Atmospheric Administration, which seems to be “what’s coming” at excessive water ranges pushed by tides, wind and storm surges that may enhance the danger of coastal flooding sooner or later. In line with NOAA, reasonable flooding is greater than 10 occasions as more likely to happen because it does now.
US Commerce Secretary Gina M. Raimondo stated the report is meant to assist companies and communities know what to anticipate and plan for the long run. A lot of the priority over sea degree rise has targeted on the menace to coastal houses, coastal companies and leisure venues. A much less apparent space of concern is the impression on agricultural manufacturing.
Florida at the moment produces greater than 300 completely different gadgets, from tomatoes to strawberries, which generated roughly $7.4 billion in money receipts in 2020. Agriculture in Florida, and significantly in South Florida, is a big contributor to the state’s financial vitality.
Securing and advancing agricultural manufacturing in South Florida means we should act now to cut back saltwater infiltration, which impacts soil, floor and groundwater high quality and plant viability, on condition that That many farms in Florida are close to the seashore. For instance, many areas within the South Dade Agricultural Space, the place about 71,000 acres had been beneath cultivation as of 2017, have elevations of lower than 3 toes above sea degree.
Even a modest enhance in saltwater infiltration into Florida’s aquifers might have a serious impression on the supply of recent water for consuming and agricultural functions. Take into account that in South Florida, 90 % of consuming water comes from underground aquifers. On the identical time, agriculture is basically depending on groundwater.
Sea degree rise is a posh and major problem, requiring a number of approaches and devoted effort over time to account for numerous elements.
Whereas we could not be capable of cease sea degree rise shortly, we will take motion to cut back among the impression of saltwater intrusion on Florida’s agricultural productiveness and farmers’ livelihoods. Florida’s rising stature as a meals producer necessitates taking this concern critically and adopting each short-term mitigation measures and long-term adaptation, resembling investing and breeding in salt-tolerant crops.
Quick-term administration practices could be applied on the farm and farm degree and present impression shortly. Freshwater flushing of salt-affected soils is a attainable approach to maintain soil salinity low; Nevertheless, this methodology is restricted by the supply of freshwater and the potential for contamination of groundwater.

Additionally it is necessary to enhance irrigation effectivity to cut back salt build-up within the soil and scale back the necessity to pump groundwater, which, in flip, will scale back the inland runoff of salt water.
The usage of strong oxygen fertilizers has been demonstrated to offer important oxygen to plant roots in salinity-depleted soils and to enhance resistance to salt and flooding. Gypsum, biochar and compost are soil amendments that may assist counteract the unfavorable results of salt-soaked soil, resembling the usage of cowl crops that scale back salt buildup. Farmers may also use raised beds to develop crops, elevating their roots.
Lengthy-term administration practices typically take an extended course of to develop and undertake and rely upon the willingness of producers to undertake new practices and, probably, make investments capital in new or modified agricultural gear.
A number of main crops grown in South Florida are delicate to excessive salinity and flooding, resembling snap beans, strawberries, avocados and papayas. There are some crops for the tropical fruit rising area with restricted tolerance to salinity and floods resembling coconut, guava, plum, dragon fruit and mango. Lastly, built-in pest administration shall be crucial to cut back illness and pest impacts arising from saltwater infiltration.
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.
