After weeks of relentless rain and flooding, and much more forecast, 2025’s droughts and hosepipe bans really feel like historical historical past. However they shouldn’t.
The United Kingdom is increasingly more stuck between those wetter winters and hotter, drier summers. What if this yr’s summer time brings water shortages once more? The apparently never-ending rainfall inflicting flooding throughout the United Kingdom at the moment may lend a hand clear up long run summer time drought issues – if we seize it proper.
The stakes are top in Speyside, house to round part of Scotland’s malt whisky distilleries. That they had to deal with 2025 being the United Kingdom’s warmest and sunniest on document, the place extended dry prerequisites ended in in style restrictions on water abstraction. More than one distilleries have been compelled into brief closures, costing the trade thousands and thousands of kilos and highlighting simply how inclined even Scotland’s famously rainy areas are to water shortage.
Whisky manufacturing represents one of the crucial UK’s greatest business water customers. Huge amounts of water are required for the distilling procedure and the product itself, so figuring out water conservation is each extraordinarily essential for the trade, and too can lend a hand others recognise the advantages.
If it used to be imaginable to retain this wintry weather’s rainfall and unlock it steadily when it used to be wanted, the country may turn out to be extra resilient to each floods and droughts with out construction dear new reservoirs.
Managing droughts with floods
Throughout Speyside, they’re checking out tactics to sluggish, retailer and often unlock water by means of running with the panorama quite than towards it. Distillers have invested in leaky dams (small limitations constructed throughout brief upland streams) to sluggish the glide of water all the way through heavy rain and make allowance the rainwater to soak into soil and recharge groundwater.
Leaky dams grasp the water at floor degree as smartly serving to it retailer underground. Water within the soil and deeper groundwater transfer throughout the subsurface a lot more slowly than over land – taking weeks or months quite than hours or days – which is why rivers nonetheless glide even after lengthy dry spells.

There are different examples of helpful interventions. Peatland recovery, wetland advent and tree planting all paintings by means of expanding brief garage within the panorama and slowing the motion of water into rivers.
Analysis throughout upland catchment spaces in Cumbria and West Yorkshire presentations how the foundations being examined in Speyside may translate to in other places. A big instructional assessment of herbal flood control proof concluded that measures expanding water garage, slowing the glide of water over the land or bettering soil construction can constantly scale back the height degree of a flood.
This rising frame of proof helps a easy however robust concept: the United Kingdom and different nations might be extra resilient to droughts and floods by means of redesigning landscapes to stay water round for longer.
3 classes for the remainder of the United Kingdom
1. Design and placement topic
Native components and hydrology (the learn about of the motion and control of water) can decide what works perfect the place. As an example, planting timber “somewhere” delivers some distance much less get advantages than planting them in the precise puts, particularly close to rivers, close to the supply of the river, or the place soil can soak up water.
2. Advantages will have to stack up or they gained’t be followed
Leaky dams and different tasks, equivalent to tree planting, are rather affordable, when put next with historically engineered flood defences or having to care for flood and drought penalties. They may be able to ship advantages at a fragment of the fee, whilst probably additionally expanding biodiversity, soil well being, carbon seize and bettering water high quality.
However there are trade-offs, which wish to be assessed early. As an example, in some circumstances, large-scale tree planting too can scale back summer time water availability in already stressed out catchment spaces. Tree canopies can briefly retailer water at the leaves, but when this water evaporates it doesn’t go back to the soil. Tree roots reinforce the soil so it absorbs and retail outlets extra water, however timber too can use extra water. The online results rely on components equivalent to local weather, soil kind and tree species.
3. Just right governance will free up investment
When water safety has transparent financial advantages, companies are prepared to interact. Then again, funding isn’t at all times non-public, and a up to date assessment confirmed public investment is ceaselessly fragmented, with inconsistent making plans laws. Strengthening general governance of these types of schemes is very important, as a result of farmers, companies and landowners are some distance much more likely to take part in the event that they get advantages.
Managing our landscapes as it should be gained’t prevent all floods or save you each and every drought, however it could make each much less serious, whilst restoring habitats, supporting farming, and protective industries that depend on unswerving water provides.
Each river sporting floodwater to the ocean represents water that may be saved for drier months. Considering forward for what occurs all the way through heavy rains will also be a part of ahead making plans for extra excessive climate in years yet to come.
