Trees Giving Up Battle, But Sustainable Farming Offers Hope

The silver bullet solution to climate change in many people’s book is to simply ‘plant a tree’. A recent study indicates that it might not be quite that simple…
Comments (2)The ability of forests to soak up man-made carbon dioxide is weakening, according to an analysis of two decades of data from more than 30 sites in the frozen north.
The finding published today is crucial, because it means that more of the CO2 we release will end up affecting the climate in the atmosphere rather than being safely locked away in trees or soil.
The results may partly explain recent studies suggesting that the amount of CO2 in the atmosphere is increasing faster than expected. If higher temperatures mean less carbon is soaked up by plants and microbes, global warming will accelerate.

Biodiverse Systems are More Productive
Biodiversity, Food Forests, Food Plants - Annual, Food Plants - Perennial, Plant Systems — by Dr. Mae-Wan Ho
Sustainable farming across the world relies on cultivating a diversity of crops and livestock to maximise internal input, and this is in marked contrast to the high external input monoculture of industrial farming, which is proving unsustainable in many respects. Indirect support for the sustainability of agricultural diversity is coming from an unexpected quarter. Academic ecologists are discovering that biodiverse systems are more productive.
by Dr. Mae-Wan Ho: Geneticist, Biophysicist and Director of the not-for-profit Institute of Science in Society .
For over three decades, academic ecologists have debated whether complex, species-rich ecosystems are more stable than ones with fewer species. Unfortunately, there are many definitions of complexity, and even more of stability; and so the debate continues.
The question most relevant to agriculture, and also most easily answered, is whether biodiverse systems are more productive. There is growing evidence that biodiverse systems are indeed more productive, although ecologists still disagree as to how that could be explained, and on the number of species needed to sustain an ecosystem, which has large implications also for conservation.

New Permaculturists in Kamiah, Idaho
Comedy Break, Food Plants - Annual, Water Harvesting — by Craig Mackintosh
While on a consultancy at the future site of the Kamiah Permaculture Institute at Kim and Julie Pagliaro’s FNA Ranch, Geoff and Nadia visit the neighbor’s (Carol and David Johnson) permaculture garden in Kamiah, ID. Just a little exposure to permaculture by their neighbour’s students set them off on the high road to sustainability. You know how the advert goes - you tell two people, they tell two people, and so on, and so on….
