High Speed Winds and Flooding

There wlll be more high speed winds and more flooding as global warming progresses. provision to help water get away is prudent.

Over the next 2 or 3 entries on this blog, I shall be reporting, courtesy of the World Resource Institute, on high speed winds.

Scientists have known for years that global warming can exacerbate storms. But our understanding of the connection between hurricanes and climate change has evolved significantly in just the past year. Here’s what the cutting-edge science shows.

If storms hover above an area of land for long periods of time, they continue to dump rain, amplifying the risk of flooding. Very recent research has established a connection between warmer temperatures and the slowing of hurricane movement. A recent study in Nature found that from 1949 to 2016, the speed of tropical cyclones declined by 10 percent globally; North Atlantic tropical cyclones slowed down 20 percent over land areas during the same period. This slowing is part of the reason Hurricane Harvey caused so much damage when it stalled over Texas last year.

So, keep the field drains and ditches in order and let the rain get away – we can expect more of it.

Carbon dioxide, cars and trees

The soil is a great collector or “sink” of Carbon dioxide. Hoiw do we manage this? Could we use CL:AIRE to do it better?

According to the World Resources Institute, “Stopping deforestation, restoring forests and improving forestry practices could remove 7 billion tons of carbon dioxide annually—the same as taking 1.5 billion cars off the road.” Now, World Bank figures on global waste production show that there is somewhere about 1.5 billion tonnes pa of MSW (Municipal Solid Waste).  About half of that would be Carbon which, as Carbon dioxide, would be around 1.4 billion tonnes.  Industrial waste production globally could easily double that, probably more. If that waste was composted, instead of burned or land-filled, it would not only lock up the Carbon, it could be used to fertilise the tree and crop growth.  It would also save wasting at least 21,000 kW hours on producing every one of the 185 million tonnes (FAO figures) of Nitrogen nutrient in the fertilisers we manufacture every year. (Yes, that is 385,000,000,000 kWh – at least!)

Only farmers and foresters have the skills and scale to do these things.  Better respect and care for them.

More People means more water

There is a real question about global and UK population. It is not about race, it is about numbers.

 

On 24 August 2017m the Water Resources Institute published a piece on their website looking at “7 Reasons We’re Facing a Global Water Crisis” in a piece written by Leah Schleifer.  With credit to them, I try here to relate those lessons to British farming and maybe farming elsewhere in developed counties that do not really think water may be a significant economic problem sooner rather than later.

 

Reason 2. More People + More Money = More Water Demand.

The Yorkshire Post reports that: “There has been a net loss nationally of 7,000 hectares of agricultural land in the UK between 2006 and 2012”. The Guardian has reported that: “Earth has lost a third of arable land in past 40 years”. There is an insidious water consumption in the UK.  While our own water consumption is rising with population growth (net plus 0.5 million people in 2016!) and what we each spend is continually, our consumption of “virtual water” (i.e. that which is involved with production overseas of what we import) is 30 times as much as UK water used, and the WWF reports that; “Taking virtual water into account, each of us soaks up 4,645 litres a day”.  That makes us the 6th largest water importer in the world.

Yes, there is a looming crisis.

Conservation farming action;

  1. Build water storage if you can. (There is some useful USA experience in building dams using old tyres.)
  2. Harvest water from roofs and concrete.
  3. Subsoil to allow roots to go deeper and move to reduced tillage – develop understanding and skills in direct drilling (or what is otherwise called “zero till”).

Water in farming

 

Does the rainbow promise better weather, wetter weather, both or more extreme weather? What can we actually do about it?

 

On 24 August 2017m the Water Resources Institute published a piece on their website looking at “7 Reasons We’re Facing a Global Water Crisis” in a piece written by Leah Schleifer.  With credit to them, I try here to relate those lessons to British farming and maybe farming elsewhere in developed counties that do not really think water may be a significant economic problem sooner rather than later.

 

Reason 1. We’re Changing the Climate, Making Dry Areas Drier and Precipitation More Variable and Extreme.

Without mentioning any particular name, one who denies climate change must either be demented or have some ulterior motive. In most farming areas, water will in general get shorter in areas where it is already short and rain, when it does happen, at higher rates and with more wind. In general terms, most climatologists agree, this trend will continue.  However, there is some evidence that we may have already started to switch off, or otherwise change, the Gulf Stream. If that turns out to be the case, the western areas of the UK may get colder, not warmer, especially in winter.

The effects of these changes will affect everything in farming including field drainage, soil organic matter, the way we control weeds in crops.  We had better be ready to respond to these pressures.  One thing is for sure – it will not stay the same.

There is one rule to watch; mostly, where rain is already short in the eastern areas, we will get less and when it happens it will be in heavy weather.  Cereal crop lodging before harvest will be an increasing risk.  All areas may experience flash flooding.

Conservation farming action;

  1. Add organic matter and reduce cultivations to reduce oxidation of organic matter.
  2. Subsoil at intervals.
  3. Maintain ditches and field drainage.

Global Warming -farming-recycling

 

Jet contrails do produce “global dimming” which reduces global warming but, in the process, produce enormous amounts of CO2. That can be removed in enormous quantities actually quite easily.

 

In the 24 June issue of New Scientist, Ed Hawkins, University of Reading, UK, and Alan Robock, Rutgers University, New Jersey, USA, both are quoted as observing that we really do need, urgently, to invent a way to remove Carbon dioxide from the atmosphere on a huge scale.

The classic way of solving a problem is to find a mirror image problem and put the two together.  Link farming (globally we need more food) and urban waste production (as global population and wealth rise, we get more unban waste) in the right way and that could deliver the invention. Well, we already have it and it has been done and on a scale that could be applied globally.

Global Warming can be arrested.

 

Hydro at Lynmouth

 

Some will remember the flood of Lynmouth in 1952 in which 34 people died.  Lynmouth, however, has a much more positive contribution to world power history.   In 1890, a small scale hydro-power system was built in the gorge above Lymouth and it was the first in the world to provide pump-back storage at the top to provide a reserve of water to produce power at peak demand. In 1987, a 500m long, 500mm diameter pipe with a 77m head was commissioned to drive a 300kW turbine. Since, the feed pipe diameter has been increased to 700mm and two more turbines. The organisers want to expand further and, to our national shame, get political prevarication and ignorance from the authorities. The truth is that hydro here lives quite satisfactorily with an SSSI and a very pretty area of natural beauty of significant tourist attraction and an example to the rest of the world. Hydro is one of the answers to reducing global warming and we need more urgently, very urgently.
