It’s up to us to keep fossil fuels in the ground. Over 500 people have come to Pau to put a stop to an offshore drilling summit organised by oil giant Total. Here’s what happened on day 1 of the conference.

Britain was one of the most prolific nation of slavers, and yet we tend to elide this from our histories. Dr Pettigrew considers British slavery within our history and as a part of the global history of slavery:
This lecture will revisit the determinants of British identity by examining the problem of slavery in British history from Roman times to the present day. Freedom and slavery provide the compass points for much of the British story but the causes, experiences, and legacies of slavery have not been fully integrated into British consciousness. An analysis of the economic, political, intellectual, and constitutional meanings of slavery in British history can suggest means to integrate slavery constructively into the story of Britain.

Biochar (a form of black carbon) has been recently heralded as an amendment to revitalize worn-out/weathered soils, increase soil C sequestration, enhance agronomic productivity, and enter into future carbon trading markets. Soil application has been the assumed target for biochar. Biochar has been shown to occasionally cause immense benefits to both crop yields and soil fertility when added to degraded/weathered soils, but simultaneously has a documented history of negative to negligible agronomic impacts. Past research, as far back as the 1800’s, has demonstrated that biochar has variable properties, which spans the full spectrum of black carbon residuals. Thus, suggesting that biochar is not a panacea for all soils. The mechanisms behind these biochar impacts are complex with multiple potential hypotheses. This presentation will summarize on-going research into the mechanisms behind the mitigation potential for N2O emissions and the role of biochar in improving water quality through nitrate and agrochemical sorption/reactions. With population expansion and the finite area of tillable ground, improving nonproductive soils with biochar could be a vital key to future global food production, food security, and energy supplies.
Rob from Intelligent Irrigation LLC shows one way to prepare Biochar. Like a bank with no money or a grocery store with no food the Biochar needs to be filled or fed with nutrients on the initial installation for immediate results. You can add the Biochar with out feeding it the nutrients first and let it absorb the nutrients from the soil but this is a longer process and may take nutrients that the plant can use in the first season. Preparing the Biochar first is a great way to amend the soil and you can do it every growing season making your soil darker and richer each year.
Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
