Let’s hear it for wildflowers

Yesterday I visited Calke Abbey and was just knocked out by a strip of wildflowers. Not just because of the visual appeal but for the food they supply to insects. I got to thinking that if everybody sacrificed some of the immaculate lawns to wildflowers it would help reduce the dangerous decline in the insect population. It would also cut down on the work and energy required for the the ‘perfect lawn’. Not to mention a reduction of pesticides and energy used.

Ban the grass – lets make wildflower areas the new garden norm!

Promoting organic gardening in a climate emergency

It is a real pity that Ryton Gardens will no longer be open to the public. It was major tourist attraction in the past and Garden Organic will lose a lot by closing it. How many other casual visitors were inspired by what they saw? A much smaller garden, closed to the public except for occasional open days is no substitute.

We need an organisation to promote and encourage organic growing both to improve food security and to combat climate change. Part of that has to be a place where good practice can be seen by casual visitors. Most of all we need an organisation that can recognise the crucial role that sustainable food growing has in combating climate change.

Maybe it is time for a new group, charity or organisation to take over that role and really get things moving. Take a look at the edible garden display at RHS Harlow Car to see what can be done. I Just wish the gardens were organic.

New York City’s largest rooftop farm

We need to do this in the UK. There are many urban roof tops that could be used to grow food where it is needed.

In the coming years the effects of global heating will have an impact on food supply. The impending crisis in the UK shows that we must have a stronger and more resilient local food supply. Conventional agriculture takes time to switch to growing different crops, but roof top gardens could be up and running within weeks.

What is likely to stop that? Local planners and health and safety concerns! I am not saying that we should ignore the safety implications of roof top gardens but

Biochar

I found this book in last week in Oxford last week, Blackwells Broad Street branch.  it just jumped off the shelf. I have known about biochar for some years but not used it in the garden. With the new plot and talk about sequestering CO2 and making better use of nutrients it could not have come at a better time.

What I like about the book is that there is some history, the use of biochar goes back to 450 BCE – 950 BCE. The soils from that era are still black, it lasts locking up atmospheric CO2 for centuries. There is a section about how it works and very useful practical information about making biochar in either in a burn pit or a TLUD: top lit up-draft gasifier.

Making a TLUD from a couple of steel barrels look relatively straight forward so that is what I will do.

It fits in nicely with the yearly timetable as I am just about to start preparing the soil for the winter. I will post some pics of the TLUD build progress soon.

IPCC report on climate change and land

Finally we get to the very basic problem – we ALL depend on the land for survival. It is the top 15 inches (38cm) of soil is that feeds us. Forget that, mess up the land, ignore it or take it for granted and we are dead, It is as simple as that.

The full report can be found here

Extracts about food security:

Coordinated action to address climate change can simultaneously improve land, food security and nutrition, and help to end hunger. The report highlights that climate change is affecting all four pillars of food security: availability (yield and production), access (prices and ability to obtain food), utilization (nutrition and cooking), and stability (disruptions to availability).

“Food security will be increasingly affected by future climate change through yield declines – especially in the tropics – increased prices, reduced nutrient quality, and supply chain disruptions,” said Priyadarshi Shukla, Co-Chair of IPCC Working Group III.

“We will see different effects in different countries, but there will be more drastic impacts on low-income countries in Africa, Asia, Latin America and the Caribbean,” he said.

The report records that about one third of food produced is lost or wasted. Causes of food loss and waste differ substantially between developed and developing countries, as well as between regions. Reducing this loss and waste would reduce greenhouse gas emissions and improve food security.

“Some dietary choices require more land and water, and cause more emissions of heat-trapping gases than others,” said Debra Roberts, Co-Chair of IPCC Working Group II.

“Balanced diets featuring plant-based foods, such as coarse grains, legumes, fruits and vegetables, and animal-sourced food produced sustainably in low greenhouse gas emission systems, present major opportunities for adaptation to and limiting climate change,” she said.

We need more allotments – now!

Here is a bit of very radical action, well not that radical; the government must make more land available for the  “90,000 people on waiting lists to get their own patch of land to grow vegetables.” In short more allotments! Not that difficult, would not cost billions and would help in all sorts of ways. See this link for more information

The British countryside is being killed by herbicides and insecticides – can anything save it?

“From orchids and moths to hedgehogs and toads, our wildflowers and wildlife are dying out. Making the meadows safe again is a huge challenge – but there are glimmers of hope”

What has been obvious this year is the lack of insect strike on the windscreen of cars! Some say that it is a good thing, but it emphasises the huge decline in insect numbers and should sound alarm bells. The link to insecticides is obvious yet there is no response from government.

Pesticides are now sold in supermarkets alongside cleaning products. A sign of how normalised they have become. This was evident in a local branch of Tesco where pesticides were shelved next to food!

In the garden it is lawns that get the full treatment. In Spring each year there are endless TV adverts show ways to blast weeds with the latest product. For a pesticde free lawn, see this site

With climate change happening now there will be a huge impact on food supplies. Keep a small area of unsprayed grass but use the rest to grow food!

Things you can do:

  • Make a pledge to become a pesticide free household, especially if you have young children.
  • Think seriously about growing some food. Start with one metre square raised beds, all the information you need it here.
  • Become more informed about pesticides in food and how to avoid them.
  • Check out the Pesticide Action Network for more information.

 

 

Soil and CO2

This is by far the best explanation of soil sequestration (storage) of CO2 in soil that I have seen. I cannot understand why farmers, gardeners and governments are not jumping on this as a way to help to drastically reduce atmospheric CO2.
