Climate change Achilles heels: Australian fires, Middle Eastern drought, British floods

Will politicians ever put their constituents’ interests first?

By 5pm on Sunday there were 271 flood warnings for England, landslides in Wales, hundreds evacuated from their homes, tens of thousands without electricity. many town centres heavily flooded and hundreds of train, plane and ferry services cancelled.

Shadow environment secretary Luke Pollard said, “The reality of the climate crisis is that more extreme weather will happen more often and with devastating consequences.

Among them are the villages and small towns of Todmorden, Hebden Bridge, Mytholmroyd, Luddendenfoot and Sowerby Bridge. But after the 2015 floods the Commons debated a motion calling for annual spending on defences to be increased from £695.3 million to £800m, Mr Whittaker was amongst those who voted against the motion, which was defeated.

Some whose homes and businesses were affected have had enough and are going to move away: “We don’t want to become a ghost town.”

In November 2019, Prime Minister Boris Johnson was vigorously heckled by local people when belatedly visiting flooded Stainforth in South Yorkshire, after expressing little concern about the floods.

After intense lobbying £33m.was granted for work in Mytholmroyd which began in June 2018 and is due to be finished in July or August 2020

Peter Lazenby points out that while this scheme struggled to get funding, the government was subsidising landowners who are increasing run-off in rainstorms by clearing Pennine moorland above the Calder Valley for grouse shooting, burning off moorland which removes mosses and other plants that absorb and store water.

In some places, water flows are controlled by bodies called Internal Drainage Boards, independent locally funded and operated statutory public bodies. Many members of these boards are landowners and seem interested only in speeding water off farmland: they dredge, straighten and embank rivers, rushing water towards cities lower in the catchment.  a recent National Audit Office report revealed significant issues with their governance, transparency and accountability.

MP Philip Davies branded it “completely unacceptable” that many of his constituents in Shipley, West Yorkshire, which was also flooded during Storm Ciara, had also been victims of the 2015 floods.

Towns in the Calder Valley, such as Todmorden, Hebden Bridge and Mytholmroyd (above) have been flooded repeatedly, partly, local people argue, because the upper catchment is unable to hold back most of the rain that falls on it.

A paper published in the Journal of Hydrology X reported experiments conducted in another part of the Pennines, the range in which Calderdale is located. It found that when peat bogs are restored, deep vegetation is allowed to recover and erosion gullies are blocked, water is held back for longer in the hills, and peak flows in the streams draining them are reduced. There has been a major shift in awareness, in and out of government, that impeding the flow of water off the land and slowing a river’s pace can reduce flooding downstream, saving lives, homes and infrastructure.

One paper suggests that reforesting between 20 and 40% of a catchment can reduce the height of floods by 19% and recommends:

In Japan, England, the Netherlands, and other low-lying countries, architects and civil engineers have developed technologies for flood control barriers, weirs and floodgates When the water rises, the computerized walls close and water fills tanks along the barrier. The weight of the water pushes the walls firmly down and keeps water from passing through. Hydraulic motors don’t need electricity to run, so they aren’t affected by power failures that can occur during storms.

Flood-affected urban areas often face a different set of problems, related to housebuilding in floodplains and damaged sewage systems. Whilst the housebuilding problem persists it is good to read about progress made in places like Stirchley.

In due course we hope to hear the residents in places like Hebden Bridge and Mytholmroyd echoing the cautious 2020 accolade of Peter Walker – Stirchley Neighbourhood Forum

“I think that the defence work that has been done so far is having some success”.
