Spotting fires from space helps India’s foresters

The three-day international workshop on forest fires organized by the World Bank and the Forest Ministry of India is a watershed event in the management of forest fires in the country (1-3rd November 2017). On the first day, discussions were held on the latest technology being used to alert foresters to fires.

Almost all fires in India are set by people intentionally or unintentionally. For instance, forest-dependent communities in central India burn the forest floor to encourage the growth of tender tendu leaves, and to collect mahua flowers which standout easily on the charred forest floor.

In the northeast and some parts of central India, forests are rotationally burnt to ashes to enrich the soil for agriculture. After a few seasons of cropping, the depleted area is left to nature and the trees grow back once again. In the western Himalayas, pine needles are cleared every year to encourage the growth of grass for cattle-fodder. When pine needles full of resin pile up year after year, it takes just one spark from a careless smoker to burn down an entire forest of enormous value.

In remote areas, forest fires may not be detected for hours or even days, leading to an irreversible loss of forest wealth. Like any other hazard, the earlier one gets to know about the outbreak, the better it is for both the authorities and the people. Since traditional ways of gathering information from people perched on watch towers are not very effective, satellite sensors that can detect heat and smoke from space have now come to the rescue of foresters across the country.   

Today, the Forest Survey of India, in partnership with the National Remote Sensing Centre, uses these satellite detections to alert foresters across the country about the exact location of forest fires. All steps in the detection and dissemination process have been fully automated – including the processing of satellite data, filtering out fires that burn outside forests, composing personalized SMSs to relevant people, as well as sending them across. This system has helped fire alerts to reach people within 45 minutes to 1 hour of detection, enabling foresters to reach the spot quickly and contain the damage.

India joins other countries in tackling forest fires

Fire has been a part of India’s landscape since time immemorial. Every year, forest fires rage through nearly every state, ravaging more than half of India’s districts. Today, with growing populations in and around the forests, these fires are putting more lives and property at risk.  Indian Space Research Organization estimates that in 2014 alone, nearly 49,000 sq.km of forests - larger than the size of Haryana – were burned during the peak fire months of February to May. And, this was a mild year compared to the recent past! 



But, forest fires can also be beneficial. They play a vital role in maintaining healthy forests, recycling nutrients, helping trees to regenerate, removing invasive weeds and lantana, and maintaining habitat for some wildlife.  Occasional fires can also keep down fuel loads that feed larger, more destructive conflagrations.  However, as populations and demands on forest resources grow, the cycle of fires has spun out of balance, and the fires no longer sustain forest health.  In fact, in many countries, wildfires are burning larger areas, and fire seasons are growing longer due to a warming climate.

Lost in a Foreign Land

Flamingos in an Indian wetlandHYDERABAD, India — It feels like a foreign land. Well, it is India, but that's not what I mean. Here I am, an infrastructure guy at the U.N. Convention on Biological Diversity's Conference of the Parties. What I am seeing in real time is global architecture at work on finding ways to protect the planet's natural resources in the face of manmade problems and changing climatic conditions. It is important work, and almost every country is laboring to find solutions that fit its unique needs. But you can imagine that common ground is not easily come by.
