Detroit to Have the Largest Urban Farm in the USA

- Adam Clare

Detroit was once a great city, then the economic collapse of car-dominated industry in the city happened. Because of the prescence of Ford and GM in Detroit the city’s urban planning focused on cars; this led to poverty and neglect of needed infrastructure.

The collapse of Detroit occurred, and now they are rebuilding. One aspect of remaking Detroit is to bring it into the 21st century by focusing on people instead of cars. An example of this is the recent announcement that Detroit will host the largest urban farming setup in America.

One surprising growth industry in the city is urban farming. Recovery Park, a nonprofit, confusingly runs a program called Recovery Park Farms, which is a for-profit. Anyway, Recovery Park and Detroit Mayor Mike Duggan announced last week an ambitious plan to create a 60-acre urban farm (35 acres of which comes from the government, through the Detroit Land Bank Authority) to be settled not with new houses for people but greenhouses and hydroponic systems for specialty produce. Recovery Park already operates a pair of smaller urban farms, growing vegetables like radishes, greens, and edible flowers and selling them to restaurants in the city.

Human Waste as an Energy Source

- Adam Clare

Human waste is a problem for every place humans live and throughout history it has been dealt with in various ways. Instead of treating human waste as a problem that needs to be removed from our towns we may want to think about it as an energy source. That’s right: turn our poo into electricity.

Anaerobic digestion of human waste can be done to convert the waste into gas. The UN University has successfully done this in Uganda and ready to take it elsewhere.

Biogas from human waste, safely obtained under controlled circumstances using innovative technologies, is a potential fuel source great enough in theory to generate electricity for up to 138 million households – the number of households in Indonesia, Brazil, and Ethiopia combined.

A report today from UN University’s Canadian-based Institute for Water, Environment and Health estimates that biogas potentially available from human waste worldwide would have a value of up to US$ 9.5 billion in natural gas equivalent.

And the residue, dried and charred, could produce 2 million tonnes of charcoal-equivalent fuel, curbing the destruction of trees.

Finally, experts say, the large energy value would prove small relative to that of the global health and environmental benefits that would accrue from the proper universal treatment of human waste.

“Rather than treating our waste as a major liability, with proper controls in place we can use it in several circumstances to build innovative and sustained financing for development while protecting health and improving our environment in the process,” according to the report, “Valuing Human Waste as an Energy Resource.”

Improve Your Soil to Fight Climate Change

- Adam Clare

Suburbanization and poor land policy have done incredible damage to soil and food systems. It turns out that the damage down to the soil itself is a contributing factor to the increased speed in human-created climate change. So to slow down the rate of climate change we can improve our soil and you can do so locally or on a large scale.

“We need to focus on the carbon dioxide supply into the atmosphere, but we really need to focus on the demand side as well,” says Larry Kopald, co-founder of The Carbon Underground, a nonprofit that’s advocates for soil carbon storage. “We have to put the CO2 back into a sink where it’s demanded and where it is useful, and improve the reabsorption of the carbon that is already out there.”

Constant plowing causes erosion, allowing soil content to flow into waterways or be blown away. And climate change itself exacerbates soil carbon loss, recent research has shown.

Cut Out Sugar and Improve Everything

- Adam Clare

Some new research points out by simply cutting out sugar one can improve basically all that ails them. In a recent research study children gave up sugar for nine days and found that much about their health improved. This implies that it might be more important to monitor one’s sugar intake more than one’s caloric intake for some aspects of increasing health.

“The whole goal was that they don’t lose weight when they switch over to the diet. It’s just they’re removing sugar to see what that effect will be,” explained Lin.

“They noticed everything got better.”

Blood pressure decreased, cholesterol decreased, liver function tests improved, and even fasting blood sugar and insulin levels in their bodies dropped.

“The freaky part of this study was that it was only nine days long,” Lin said.

Europe Meets 2020 Emissions Targets Early

- Adam Clare 1 Comment

Europe has already beat its 2020 gas emissions target and it’s only 2015! This is good news because we need to reduce our energy consumption and our global output of greenhouse gas emissions. This demonstrates to the rest of the world that not only is it economically feasible to reduce emissions it proves that it can be done quicker than climate change deniers claim.

A report by the EU’s environment agency on Tuesday said 2014 emissions were 23 percent lower than in 1990. The EU’s goal is to achieve 20 percent reductions by 2020, but the report said the bloc is headed for 24-25 percent cuts with current measures to fight climate change.
