Flood alert needs upgrading
BANKE DISTRICT, 24 September 2013 (IRIN) - Close to half a million residents in Nepal’s mid-western Banke District depend on Bhadra Bahadur Thapa, 58, a government gauge reader, to monitor water levels around the Rapti River basin in Kusum village, some 550km southwest of the capital, Kathmandu.
“My job is to communicate this vital information every hour, or sometimes every minute, depending on the weather,” he said. Thapa routinely receives hundreds of calls from local residents after a heavy rainfall.
His job is part of a recent government effort to reinforce Nepal’s existing community-based early warning system with better real-time data.
The Rapti River is one of 6,000 rivers and streams that traverse this Himalayan nation of 25 million, and is often at risk of flooding during the country’s annual monsoon season from July to October.
When river water reaches warning level - indicated by telemetry readings at observation sites set up in 2008 at various points along the river’s edge and transmitted to Thapa’s office - he immediately communicates this data to key local disaster risk reduction and response teams from the government, army, police and Red Cross, who in turn raise the alarm in local communities.
“Usually, it takes four to five hours for flood waters to reach the nearest village [downstream] from Kusum, so people have sufficient time to leave their homes,” Rishi Sharma, director general of the Department of Hydrology and Meteorology (DHM), told IRIN in Kathmandu.
The DHM comprises 280 rainfall centres, 100 climate centres and 180 hydrology centres, and is the key agency leading the early warning system in Nepal, but it needs upgrading, said Sharma, particularly in the area of warning and providing real-time data.
The World Bank has been supporting the country since June with ‘Building Resilience to Climate Related Hazards’, a programme to strengthen the government's capacity to mitigate climate related hazards by improving the flood forecasts.
“There is no system for issuing authoritative warnings for weather and climate related disasters to government authorities and key user groups,” said Poonam Pillai, the World Bank’s senior environmental specialist, South Asia region.
The government started stepping up its early warning efforts five years ago with a community based early warning system in 25 places near seven river basins - Karnali, Babai, Narayani, Seti, Rapti, Bagmati and Koshi - across the country, said DHM officials.
“Much progress has been made in community-based early warning in Nepal. However, we need to make sure that early warning is part of a comprehensive approach for disaster risk reduction at the community level,” disaster management expert Moira Reddick, coordinator of the Nepal Disaster Risk Reduction Consortium (NDRRC) explained.
“This system has worked very effectively and is making vulnerable communities aware and prepared,” Lok Narayan Pokharel, from the NGO, Centre for Social Development and Research Nepal (CSDR), told IRIN in Banke district. CSDR is the key agency working with the government on the early warning system.
Making a difference
“We don’t have to stay awake all night and panic when it rains, as the communication system is better now,” 30-year old Laxmi Dixit, a recent flood victim from the remote Tepari village in the Holiya Village Development Committee area, nearly 600km southwest of Kathmandu, said.
Dixit’s was among 112 families relocated by the government after they were displaced from their village by flooding in July. Since then, they have all been living in Naya Busty, a safer village about 5km away from the Rapti River.
However, local authorities say the early warning system has to go beyond just warning the villagers.
“Early warning is not just about… [raising an alarm in good time among] people, but also to guide them for [better] preparedness in future by building strong infrastructure like river embankments, and having enough resources to reduce risks,” said Banke’s chief district officer, Jeevan Prasad Oli.
Over the past decade, more than 600 people have died in floods and over 10 million people have been affected, according to Nepal Red Cross. The worst year was 2004, when 130 people were killed - the highest death toll - and 7 million were affected. So far in 2013, at least 16 people have died and more than 35,000 have been affected by flooding.
