Kamal Meattle on how to grow fresh air

Kamal Meattle has a vision to reshape commercial building in India using principles of green architecture and sustainable upkeep (including an air-cleaning system that involves massive banks of plants instead of massive banks of HVAC equipment). He started the Paharpur Business Centre and Software Technology Incubator Park (PBC-STIP), in New Delhi, in 1990 to provide "instant office" space to technology companies. PBC-STIP's website publishes its air quality index every day, and tracks its compliance to the 10 principles of the UN Global Compact, a corporate-citizenship initiative.

Janine Benyus: Biomimicry in action

In the world envisioned by science author Janine Benyus, a locust's ability to avoid collision within a roiling cloud of its brethren informs the design of a crash-resistant car; a self-cleaning leaf inspires a new kind of paint, one that dries in a pattern that enables simple rainwater to wash away dirt; and organisms capable of living without water open the way for vaccines that maintain potency even without refrigeration -- a hurdle that can prevent life-saving drugs from reaching disease-torn communities. Most important, these cool tools from nature pull off their tricks while still managing to preserve the environment that sustains them, a life-or-death lesson that humankind is in need of learning. 

As a champion of biomimicry, Benyus has become one of the most important voices in a new wave of designers and engineers inspired by nature. Her most recent project, AskNature, explores what happens if we think of nature by function and looks at what organisms can teach us about design.

John Kasaona: How poachers became caretakers

John Kasaona is a leader in the drive to reinvent conservation in Namibia -- turning poachers into protectors of species. It’s a standard nature-documentary scenario: a pristine animal habitat under constant threat by the people who live there, hunting, camping, setting fires. But John Kasaona knows there is a better way to see this relationship between people and environment. As the assistant director for the Integrated Rural Development and Nature Conservation (IRDNC) , Kasaona works on ways to improve the lives of rural people in Namibia by involving them in the management of the lands they live on -- and the species that live there with them.

Kasanoa's Community-Based Natural Resource Management (CBNRM) program helps rural villages set up communal conservancies, which manage and use local natural resources in a sustainable manner. Essentially, it's about restoring the balance of land and people to that of pre-colonial times, and allowing the people with the most interest in the survival of their environment to have control of it. His work was featured in the recent film Milking the Rhino.

“Perfume Grass” Could Solve Problem of Antibiotics in Water Supply

from cleantechnica.com:

Researchers at Michigan Technological University are on to a simple, low cost solution to the complicated problem of keeping antibiotics out of water supplies.  In a study of vetiver grass grown in antibiotic-laden water, they found that 95.5% of the drugs were removed from the water and taken into the plant tissue.

Vetiver grass is sturdy, spiky grass native to India that is well known for its use in erosion control.  Vetiver grass is also used in perfumes and in handicrafts for local economic development projects.  In a somewhat ironic twist given its aromatic properties, vetiver grass is also an up-and-comer in the growing field of phytoremediation, in which plants and wetlands are used to remove contaminants from wastewater and stormwater.
