The age-old practice of turning the soil before planting a new crop is a leading cause of farmland degradation. Many farmers are thus looking to make plowing a thing of the past.

Biofuels have failed to live up to their early environmental promise, but fuels made from plant waste and weeds may turn this around.

Ten years ago, running your car on biofuels meant covertly topping up your tank with chip fat. Now petrol is routinely mixed with ethanol made from corn, and diesel with squeezed rape, oil palm and soya. The current generation of biofuels was rushed onto the market in response to escalating concern in Europe about climate change, and in the US about energy security. But almost before the biofuels industry has got going, it has run into major problems. It has swiftly become a victim of its own success, gobbling up land and water in a way that has frightened the world.

India carries a huge livestock population. Small ruminants, namely, goats and sheep, play a vital role in securing the livelihood of small and marginal farmers and landless labourers. Such animals should not be blamed for the ecological degradation, soil erosion and desertification caused by human activities.

The biogas yield of rice straw during anaerobic digestion can be substantially increased through solid-state sodium hydroxide (NaOH) pretreatment. This study was conducted to explore the mechanisms of biogas yield enhancement.

The combine harvesting technology which has become common in the rice

A ray of hope is dawning in a few hundred villages of Washim and Akola districts, thanks to a project called the Integrated Sustainable Agricultural Programme (INSAP) being implemented by Yuva-Rural (Youth for Unity and Voluntary Action) with the help of Swiss-Aid India.

Rice is the most important Kharif crop of Punjab. With the increase in production of rice there is concomitant increase in the production of residue (rice straw), which is approximately 18.75 MT. About 80 percent of the rice residue it burnt in the fields, particularly after harvesting rice by combine harvesters.

Residue burning practice is followed in major Indian states of Uttar Pradesh and Punjab. Agricultural residue burning in the fields and used otherwise for rural domestic needs is responsible for a large number of toxic emissions, which are a health hazard.

Crop residue burning results in the emission of many a toxic pollutants. These emissions can travel long distances affecting thereby the entire region. Due to these emissions the air quality of the region worsens, which results in nose and throat itching and burning, and irritation of the airway tract.
