Rhine-Ruhr, or Essen-Düsseldorf, is among the world's least recognized larger urban areas (Figure 1). Germany does not designate urban areas according to the international standard, and for that reason the Rhine-Ruhr does not appear on the United Nations list of largest urban areas. Yet, in reality this contiguous urban area is Germany's largest urban area, a position as it has held since at least the end of World War II. The Rhine-Ruhr is the third largest urban area in Western Europe, trailing only Paris and London. The area was one of the strongest early urban industrial areas in the 18th century and continued as a major manufacturing and coal mining center through the first half of the 20th century.
Why does PRADAN support small decentralized farm-based rainwater harvesting rather than big projects? In short, we made a commitment to poor, small-holder farmers to ensure happy, self-sustainable livelihoods in their own farms. Fifty seven percent of Indian rural households own some land, the majority of farms less than one hectare and about half depend entirely on seasonal rain . Many of these farmers do not have access to irrigation projects tied to big dams and government-sponsored canal programmes.
The above map shows the levels of food insecurity in America. The darkest areas on the map mean that at least 30 percent of that area's population is food insecure. While the lightest areas are between 4 and 14 percent.
Last week, EPA released the fifth drinking water infrastructure needs survey and assessment. This survey indicates that $384 billion is needed to invest in things like pipes, treatment plants and storage tanks to meet the needs of 73,400 water systems across the country over the next 20 years. This huge need represents challenges to delivering safe drinking water to homes and businesses, especially as we face aging infrastructure worldwide.
Dr. Angela Belcher, a materials chemist and one of the world’s leading scientists in nanotechnology was announced today as the recipient of the 2013 $500,000 Lemelson-MIT Prize.
Belcher has drawn inspiration from nature and its ability to create materials.
-She believes that if organic and inorganic materials can combine in nature to produce exquisite structures, similar processes can be used in the lab to create things of which nature hasn’t yet dreamed. She has used these lessons in biology to design novel, hybrid organic-inorganic materials that have been used to create environmentally-friendly batteries and clean transportation fuel, among other inventions with both commercial and social value. The Lemelson-MIT Prize, which honors an outstanding mid-career inventor dedicated to improving our world through technological invention, has been awarded annually since 1995.
# Good argument for new paradigm concepts and a vision of "awareness-based, love-infused, presence-centered, evolutionary leadership” (but beyond green meme concepts :-)) drawing on Steiner, Campbell, Kegan, Torbert, Wilber, etc. The article gives a solid overview over qualities, concepts and practices that are emerging and gives a taste on what a new paradigm of leadership and development "in relationship to nature, community and meaning" could actually look like embodied, and, most importantly, scaled up.

From northern Europe to Florida, highway planners are rethinking roadsides as potential habitat for native plants and wildlife. Scientists say this new approach could provide a useful tool in fostering biodiversity.
Seattle City Light and the Bullitt Foundation have announced a first-of-its-kind model for financing advanced energy-efficiency improvements in new and existing commercial buildings.
The model has to key differentiators from typical financing plans. First, an energy-efficiency meter measures real-time energy savings and allows it to be sold as it occurs. Second, a 20-year contract is inked between the utility and energy-efficiency investors.
Permaculture is notoriously hard to define. A recent survey shows that people simultaneously believe it is a design approach, a philosophy, a movement, and a set of practices. This broad and contradiction-laden brush doesn’t just make permaculture hard to describe. It can be off-putting, too.
There is little question that suburban strip malls represent an unsustainable architecture. Totally automobile-dependent, marked by large surface parking lots, and remarkably inefficient at using land, strip malls generate much more pollution...
Housing is a key component of any governments’ comprehensive urban plan. The cornerstone of any good housing sector is a plan to provide affordable housing options so that all citizens have a place to call their own. Traditionally, housing was considered affordable if it cost no more than 30% of an individual’s or family’s income. Such a simplistic measure fails to account for a wide range of factors that can potentially affect the affordability of an area, key among them being transportation costs. The Center for Neighborhood Technology believes that they may have rectified this problem with the creation of their Housing + Transportation (H+T) Affordability Index.
