Tribal communities are a rich source of traditional knowledge. Initiatives that respect their knowledge while taking them through the process of development could be enriching to all the partners involved. Here is a case of a partnership which has been mutually enriching.

In their article discussing the impacts of farm animal production on climate change, Koneswaran and Nierenberg (2008) called for "immediate and far-reaching changes in current animal agriculture practices" to mitigate greenhouse gas (GHG) emissions. One of their recommendations was to switch to organic livestock production, stating that raising cattle for beef organically on grass, in contrast to fattening confined cattle on concentrated feed, may emit 40% less GHGs and consume 85% less energy than conventionally produced beef.

The vast majority of the nearly 2 million miles of paved roads in the United States are surfaced with asphalt pavement, which is made by combining a thick hydrocarbon mixture known as liquid asphalt binder with sand, gravel, or crushed stone ("aggregate"). Each year about 60 million tons of hot-mix asphalt (HMA) pavement are laid on U.S. roads, according to figures presented last spring at the 12th Annual Minnesota Pavement Conference.

This study provides insights on ground water market in minor rain fed tank irrigation milieu and also examines the conjunctive use with focus on water productivity and groundwater extraction in tank irrigation system. The study was taken up in three minor irrigation tanks in Tamil Nadu state. All are rain fed tanks depending entirely on rainfall.

Living near traffic has been associated with asthma and other respiratory symptoms. Most studies, however, have been conducted in areas with high background levels of ambient air pollution, making it challenging to isolate an independent effect of traffic. Additionally, most investigations have used surrogates of exposure, and few have measured traffic pollutants directly as part of the study.

By international standards, water supplies in Perth, Western Australia, contain high trihalomethane (THM) levels, particularly the brominated forms. Geographic variability in these levels provided an opportunity to examine cross-city spatial relationships between THM exposure and rates of birth defects (BDs).

Compact fluorescent lamps (CFLs) are about 75% more energy efficient than incandescent light bulbs and last 10 times longer, and thus have quickly become a modern-day environmental icon. The U.S. Environmental Protection Agency (EPA) estimates that about 290 million CFLs were sold in 2007. But CFLs do have one dim spot on their otherwise bright green image: the mercury that makes the bulbs' inner phosphor coating fluoresce and produce light.

Despite efforts to reduce lead in the environment by removing lead in gasoline and banning lead-based paint, an estimated 310,000 U.S. children 1

Shivalik foothills in Himachal Pradesh are marked by frequent crop failures due to erratic rainfall, lack of irrigation facilities, serious soil erosion problem, unemployment and poverty. During the earlier days the villages of the region had their own ponds, which served the society. Over the period of time bond of the villagers over such common property is getting weak.
