Fryent Country Park ponds still badly affected by drought despite the recent rain

 

 

Affinity Water supplies water to parts of the north of Brent. They warned a few weeks ago that to avoid a hose pipe ban there would need to be above average rainfall over the Autumn and Winter to make up for the impact of the summer drought. If rainfall continued below average, they would need to introduce a hose pipe ban in 2023.

Following the recent heavy rainfall some people have suggested reservoirs would soon be back to normal levels. Yesterday I walked through Fryent Country Park to see how the many ponds were affected by the rain. giving an indication of what might be happening to reservoir levels.

Some were still completely dry and covered in vegetation.  Barn Hill pond on top of Barn Hill had recovered somewhat but still well below normal levels. It has a different geological base from the other ponds and there's some mystery about how it fills with suggestions of springs in the area.

The other ponds have a clay lining. Clay used to be 'puddled', beaten down to remove all the air, making a waterproof surface that retained water in the pond. Tools might be used to beat down the clay but in the past cattle would be driven through to compact the clay and in modern times when ponds are constructed  in schools pupils in wellies do the job! 

In a drought the clay is exposed to the air and the sun's heat and will crack, leading to the loss of water when the pond refills. Cracks can be seen in the dried-out pond in the photograph above. Loss of ponds in the Country Park will impact on the survival of already threatened frogs, toads and newts as well as other pond life such as dragonflies and damsel flies that give much pleasure to visitors.

Maintenance work has been done on some of the ponds and may explain the differences in water retention. Below are some of the ponds I checked yesterday, beginning with Barn Hill pond.

Barry Gardiner joins Corbyn's Shadow Cabinet

Barry Gardiner, MP for Brent North, was reportedly booed by fellow Labour MPs yesterday evening when he had the temerity to speak up in defence of Jeremy Corbyn's leadership. Corbyn has now appointed him shadow Energy and Climate Change Secretary.

Gardiner is my member of parliament and I have clashed with him many times, as well as agreed with him on some issues, such as the Prevent Strategy. I stood against him in the General Election before last as the Green Party candidate.

We share a concern about the environment and climate change and although our specific policies, not least on the major question of whether our current economic system based as it is on continuing economic growth is compatible with tackling climate change, may differ, I welcome his appointment as strengthening the Labour Party's approach to the issue.

This is what he had to say in a recently updated Huffington Politics LINK article that demonstrates his ability to analyse the political implications of resource competition.:

Exactly one week before the Queen’s Speech President Obama gave a speech - not in London, but in New London, Connecticut - to the United States Coast Guard Academy. He said: “I am here today to say that climate change constitutes a serious threat to global security, an immediate risk to our national security, and, make no mistake, it will impact how our military defends our country... And so we need to act - and we need to act now.”
He said that climate change would shape how every one of America’s services plan, operate, train, equip and protect their infrastructure, because climate change poses risks to national security, resulting in humanitarian crises, and “potentially increasing refugee flows and exacerbating conflicts over basic resources like food and water.”
Last summer I was critical in this House of the government’s decision not to provide financial support to the Italian government’s coast guard operation to rescue refugees from Libya. The Government’s responded to me then that such rescue operations acted as a “pull factor” and were only increasing the number of attempts. I thought it an obscene argument then and in the intervening months we have seen that it was not only obscene, but wrong. The numbers have increased. This Saturday the Italian Coast Guard announced that more than 4,000 migrants had been rescued off Libya’s coast in 22 separate operations in just one day.
We need to look deeper into why those migrants are coming in the first place. It would be convenient for me to point to the British and French air strikes, not to mention the failure to prepare a post-Gadhafi strategy that left that country in chaos. But I want to look deeper still into why the civil war started in the first place. It was part of a much wider pattern of regional upheavals that we called the Arab Spring that began in Egypt in 2010 with the uprisings in Tahrir Square.
If we track back those disturbances we come inexorably to the 2010 drought in Russia’s wheatbelt. It was the longest and most severe drought in Russia in over 50 years. The country lost 25% of its crop and it led Russia to impose an export ban on wheat that it had traditionally exported to Egypt. The food crisis in Egypt was the pre-curser to the Arab Spring. It was the same in Tunisia and the rest of the Arab world.
On the 9th September 2010 when the UN Food and Agriculture Organisation warned that Syria’s drought was affecting food security and had pushed 2-3 million people into “extreme poverty” few people took any notice. In fact Syria had suffered four successive years of drought: the longest and deepest failure since records began in 1900. The losses from these repeated droughts were particularly significant for the population in the northeastern part of the country, in Al-Hasakeh, Deir Ezzor and Al-Raqqa.
Small-scale farmers were worst affected — many of them not able to cultivate enough food or earn enough money to feed their families. Herders also lost 80-85 percent of their livestock. Thousands left the northeast and migrated to informal camps close to Damascus. Experts warned at the time, that the true figure of those living in “extreme poverty” was higher than the official 2-3 million estimate. What is astonishing in military terms is that nobody predicted in September 2010 that such a tinder box might give rise to civil unrest and civil war only six months later.
The International Institute for Strategic Studies is very clear on the impact of resource shortages. In 2011 they published a report claiming that climate change “will increase the risks of resource shortages, mass migration and civil conflict” and the MoD has said that it will shift “the tipping point at which conflict occurs”.
The degradation of natural resources such as forests and freshwater has removed much of the resilience that societies formerly enjoyed. And what is perhaps equally disturbing is that we are beginning to see evidence that efforts to mitigate or adapt to climate change by some countries can actually shift increased risk onto others.
Climate change brings pressures that will influence resource competition between nations and place additional burdens on economies, societies and governance institutions around the globe. These effects are threat multipliers. They will aggravate those things that lead to conflict: poverty, environmental degradation, political instability and social tension. If Britain is to play a positive role in the world then this must be understood by our military and we must adapt.
We as politicians have to understand that the greatest threats to our security are no longer conventional military ones. You cannot nuke a famine. You cannot send battleships in to stop the destruction of a rainforest. But you can spend money on clean technology transfer that enables countries to bring their people out of poverty without polluting their future. You can invest in adaptation measures that will protect communities from the effects of climate change that are already placing their societies under stress.
