I blog about environmental and social justice issues because I am very concerned about the health of the interdependent web of life of which we are a part.

Problems with Agriculture

I recently posted - muttering to myself- about the lack of discussion on climate change in the media.  As I stated earlier, Al Jazeera ia an exception.  Dahr Jamal wrote an aricle on July 4, 2011 entitled The Decline of Agriculture?  You can find it at http://english.aljazeera.net/indepth/features/2011/07/201173114451998370.html
Ze starts with a warning from the Food and Agriculture Organisation about the delterious effects climate change will have on agriculture and hence, on human eating. The FAO warned that climate change will reduce food production, and therefore, cause millions of people to go hungry - or starve.  (The author also quotes the US National Climate Data Center as saying that April 2011's weather extremes were unprecedented.  Don't worry , the relevance of this point will be apparent later on.)
Ze then moved into a discussion of current agricultural practices.  Our industrail agribusiness methods are apparently quite disastrous.  Dahr Jamal quotes Dr. Bomford, a plant and soil scientist, as saying
Clearing land for farming releases carbon into the atmosphere and that contributes to climate change.  Then by farming it, using cultivation causes soil to be lost in wind and erosion, and that topsoil took thousands of years to from.  One extreme weather event can cause us to lose thousands of years of soil.
Please see the comment above on April's weather extremes and picture such extremes becoming the new normal as predicted by climate change models. Goodbye soil.  Goodbye cheap plentiful food.
Cultivation istn't the only problem with our agriculture. Our use of fertilizers derived from petroleum is also problematic. Dr Ryerson is quoted as follows:
The world's agricultural systems rely substantially on increasing use of fertilizers.  But now, the world's farmers are witnessing signs of a declining response curve, where the use of additional fertilizer yields little additional food product. At the same time, fertilizers and intensive cropping lower the quality of soil. These factors will more and more limit the possibilities of raising food production substantially and will, at a minimum, boost relative food prices and resulting hunger for many.
Looks like starvation is on the menu for many of us as food isn't going to be!   Weirdly, our penchant for large agribusiness - huge industrial farms - isn't a logical choice when one considers productivity. The bigger the farm , the less productive it is. Astonishing fact, isn't it?  "Vandana Shiva....points to reams of studies by universities, the UN and FAO showing that the most productive form of agriculture is not our modern, tractor-serviced, big field monocultures, but multilple crop..., manual labour intensive smallholdings."  (page 170, Good News For A Change, Suzuki and Dressel.) In  fact, the UN came out with another report called Agroecology and the Right to Food which urged that we shift towards agro-ecology in order to deal with the problems of hunger, climate change, and poverty.
As defined by the UN, agroecology "applies ecological science to the design of agricultureal systems taht can help put an end to food crises and address climate change and poverty challenges.  It enhances soils productivity and protects crops agaisnt pests by relying on the natural environment such as benefical trees, palnts, animals, and insects."   Sounds like organic gardening to me.  But whatever agroecology sounds like, it is a multiple crop system that relies on manual labour - and it is incredibly productive. 
Even more weirdly, governments have ignored the facts and chosen to subsidize agribiz instead of small family farms. Even worse, in Canada the federal government has had a settled and considered policy of squeezing small holders out of existence.  "During the late 1960s, the federal government instigated a major study into the future of Canadian agriculture. The study concluded that there were too many farmers in Canada (emphasis mine) and recommended that approximately two-thirds of them be eventually eliminated (page 94, Writing Off The Rural West, editors Roger Epp and Dave Epson..)

So the Canadian government chose to encourage large farms that require massive inputs of chemical fertilizers and pesticides; that destroy the soil; increase greenhouse gas emissions; and are actually less productive than small holdings.   These existing  problems with agribusines are now exacerbated by the effects of climate change.

A Green Roof

A green roof has many advantages.  Advantages of a green roof include that they:
  • are aesthetically pleasing
  • reduce city "heat island" effect
  • reduce carbon dioxide impact
  • reduce summer air conditioning cost
  • reduce winter heat demand
  • lengthen roof life by two to three times
  • remove nitrogen pollution in rain
  • neutralize acid rain effect
  • reduce noise
  • reduce stormwater runoff
  • provides songbird habitat (list  from http://horticulture.psu.edu/cms/greenroofcenter/history.html )
Carbon sequestration may be one of the most important effects of a green roof.
Using plants to do this is referred to as terrestrial carbon sequestration. Through the process of photosynthesis, carbon dioxide is removed from the atmosphere and stored as carbon in biomass. If net primary production of these ecosystems exceeds decomposition, then these systems become at the very least a short term sink for carbon. http://www.hrt.msu.edu/greenroof/
So, if you are building or renovating, consider installing a green roof.  Your new abode might look
like this! (  It is the Nanyang Technological University in Singapore.  Yes, that is a building under that greeneery!)  Even if it doesn't, you will have created a positve example  and energy in the world.

Climate Change Bad and Getting Worse

Al Jazeera and the UK Gaurdian seem to be the only media outlets that talk about climate change. Al Jazeera points out that it is bad and getting worse:
So far human greenhouse gas emissions have raised the temperature of the planet by one degree Celsius.
The Al Jazeera article goes on to list impacts felt RIGHT NOW - including high food price - floods -wildfires - loss of biodiversity - and  acidifying oceans. Meanwhile, the UK Guardian has created a huge FAQ on climate change in the hopes of educating people.  Find it at  http://www.guardian.co.uk/environment/series/the-ultimate-climate-change-faq

Media in Canada don't seem to pay attention to climate change - and  Canada's politicians do nothing.  The Conservatives  do nothing - and are reviled for it - but the Liberals signed the Kyoto Accord and then did dick-all as well.   Why?   Well , Stephan Dion was soundly punished at the polls for presenting a green platform that took climate change seriously.  Therefore, presumably our politicains do nothing because we don't really want them to take action.  We  aren't  exactly rioting in the streets,are we?  ( Well, we're not rioting  because we're worried about the impacts of climate change.)

Denial ain't just a river in Egypt!   And arguing with people in denial ends up reinforcing their defenses - what's a poor activist to do?  Work through ready made communities - church groups - chambers of commerce -  etc and tailor your message to the group.

And work on yourself - meditate - and work on seeing everyone in the world as connected to everyone and everything - and as worthy of your love. Then, when you carry out your activism, you will do so with loving kindness  and compassion.  I think it's the only chance we've got.....
