But this is not my review of Soil, but the title is serving as a jumping-off point for some other things I've been reading and thinking about. Such as how we're facing this massive increase in population over the rest of this century.
It seems we're expected to increase world population from six to eight or nine billion before we top out. And somehow we need to feed all these people, an accomplishment made all the more difficult by peak oil, global warming, and the question of equitable distribution. The argument is made by industrial agriculture advocates that without high-tech, capital intensive farming, we'll never be able to feed everyone.
But here's the thing; modern agriculture is not a solution. Hell, pre-1900 agriculture is not a solution. Agriculture is the problem. Not the only one, true, but approximately a fifth of the problem. It's not that global warming will impact our ability to grow food in different areas, it's that growing food is contributing to global warming.
The FAO reports that:
[...]estimates of greenhouse gas data show that emissions from agriculture, forestry and fisheries have nearly doubled over the past fifty years and could increase an additional 30 percent by 2050, without greater efforts to reduce them.
[...]Agricultural emissions from crop and livestock production grew from 4.7 billion tonnes of carbon dioxide equivalents* (CO2 eq) in 2001 to over 5.3 billion tonnes in 2011, a 14 percent increase. The increase occurred mainly in developing countries, due to an expansion of total agricultural outputs.
Meanwhile, net GHG emissions due to land use change and deforestation registered a nearly 10 percent decrease over the 2001-2010 period, averaging some 3 billion tonnes CO2 eq/yr over the decade. This was the result of reduced levels of deforestation and increases in the amount of atmospheric carbon being sequestered in many countries.
* Carbon dioxide equivalents, or CO2 eq, is a metric used to compare emissions from different greenhouse gases based on their global warming potential.
