(2023:广东六校联考)In the world of water,.2021 was another year for the record
books.Parts of Western Europe suffered from deadly floods while large areas of the
southwestern United States remained locked in a massive drought.
One might think that our impressive water management would safeguard society from
such catastrophic events.Yet when it comes to water,the past is no longer a good guide for the
future and most of the water engineering is unprepared for consequences of increasingly
occurring extreme weather.One of the most alarming wake-up calls came from the city of
Cape Town,where the water taps of 4 million residents were nearly forced to be shut off after
severe drought dried up its reservoir ()
Appealing as it might be,the solution is not to further build bigger and higher dams(
that often result in more disastrous flooding.Rather,it is to work more with natural
processes.
The Netherlands avoided major damage from the historic floods in July 2021 thanks to its
recently completed project,which gives river room to spread out by redirecting floodwaters
into wetlands,lowering parts of the stormy river by more than a foot.Agricultural practices
offer another strategy.Scientists have found that boosting organic matter in the soil by 1%can
increase the soil's water-holding capacity by up to 18,000 gallons per acre,creating flexibility
to both intense rains and dry periods.This means farmland practices such as the planting of
cover crops can not only raise output but improve water management.
Solutions don't come easily,but they are key to a livable future.While it's too late to avoid
the impacts of climate change,we can avoid the worst of those impacts by investing more in
such nature-based water solutions.
