A crucially important trend in climate change news focuses on soil.
In the United States, the greatest contributors to climate change have been the energy and transportation sectors, so federal responses have focused on emissions that result from burning fossil fuels. The resistance to regulated changes has come from private interests with business models that depend on fossil fuels (and politicians that support them).
The U.S. priority on fossil fuels makes sense, and it engages a good fight, but it’s not the entire story.
For at least the past ten years, public interest organizations have been pointing to Nature’s plan for moderating climate change. That plan depends on forests and soils, both of which are very good at absorbing and storing (sequestering) carbon.
Climate change has been accelerated by cutting down vast areas of forest to free land for agriculture. The negative effects of deforestation have been recognized, and initiatives (never enough) have been launched to control this practice and let the trees do their work.
Nature’s plan also as been compromised by agricultural practices, beginning with deforestation and continuing with a variety of poorly conceived land-use and land-management practices.
The good news on this front is that almost all the countries that have joined in the Paris Climate Agreement have stated that they will improve agricultural practices in their efforts to curb climate change.
According to the World Resource Institute, agriculture contributes 13 percent of greenhouse gas emissions and, with land-use changes, 24 percent of net emissions.
Agriculture is not as important as a climate change factor in the U.S. as I developing countries, but it’s still a significant contributor. California, which has a huge role in agriculture, has recognized this reality and initiated the Healthy Soils Initiative, discussed in a recent column (see ongardening.com/?p=2680) .
In this regard, California has been well ahead of the federal pace: U.S. Department of Agriculture has recommended that farmers voluntarily adopt carbon-capturing practices, but has done little more in deference to policies on energy and transportation.
In more good news, the U.S. position is changing, In December of 2016, the National Science and Technology Council (NTSC) released the report, “The State and Future of U.S. Soils: Framework for a Federal Strategic Plan for Soil Science.” The NTSC is “is the principal means by which the Executive Branch coordinates science and technology policy across the diverse entities that make up the Federal research and development (R&D) enterprise.”
To see this report, visit www.whitehouse.gov and search for “soils.”
In related actions, on January 11th, Regeneration International, a coalition of consumer groups, launched its “Soil is the Solution” briefing for members of Congress. A team of experts will seek opportunities to talk to our elected policy-makers (or their staffs).
Also, on January 19th, Former Vice President Al Gore will unveil a sequel to “An Inconvenient Truth,” his 2006 climate-change documentary. The new film surely will emphasize the role of agriculture in climate change. The sequel will debut at the Sundance Film Festival, and will be released in theaters later in 2017.
Efforts to control climate change must begin with large-scale actions, but they are also appropriate for home gardeners. We all have a stake in the future!
