Nepal’s forest users cope with climate stress on water

OM ASTHA RAI

DANG, Sept 14: In June this year, thousands of farmers, especially in Nepal´s western region, were wrestling with rain deficit, constantly gazing toward the sky devoid of monsoon clouds.

In some areas badly affected by the weak monsoon, farmers were seen irrigating their parched crop fields with water supplied through pipes.
But, in Hapur village of Dang district, the picture was entirely different. Even as farmers reeled under the drought-like situation elsewhere, the Hapur villagers remained unaffected.

“The monsoon was late and weak this time around,” says Puni Kala Khadka, president of Chandra Jyoti Community Forest Users Group (CFUG), which has 124 families of Hapur as its members. “But, we had no problems at all.”

Before this year´s paddy plantation season began, Chandra Jyoti CFUG built a canal to use irrigation water from a local stream. “Had this canal not been built, our crop fields would have parched like elsewhere,” says Khadka.

Due to what scientists have dubbed as a result of climate change, monsoon rains, the backbone of Nepal´s agriculture, are becoming erratic. Farmers are becoming more vulnerable to threats of droughts or floods than ever before.

This year, Meteorological Forecasting Division (MFD) announced monsoon´s arrival one week later than the usual date. But, even thereafter, it remained ineffective till mid-July, sparking fears of dismal crop output. Farmers felt relieved only after monsoon rains became more even and intense by July end.
“Rains are no longer reliable,” says Khadka. “Fortunately, we have this irrigation canal now.”

However, hundreds of thousands of farmers are not as fortunate as the Hapur villagers. They are still deprived of irrigation facilities. According to the Department of Irrigation (DoI), nearly 500,000 hectares of Nepal´s cultivable land still lack irrigation facilities.

Worse, the rate at which the DoI is expanding the irrigation coverage area is disappointing. “At the current rate, it will take us at least 25 years to expand irrigation coverage to the whole cultivable land,” says Basistha Raj Adhikari, a water resources management specialist.

Adhikari says the pace of irrigation coverage expansion cannot be accelerated only institutional and policy reforms are carried out. “In the existing scenario, farmers´ dependency on rain water cannot be done away with,” says Adhikari.

However, farmers in remote villages cannot afford to wait for institutional and policy reforms. They have already started to deal with their problems in whichever way or scale they can. And, forest users, affiliated to over 18,000 groups and spread across the country, are turning out to be a pioneer in this battle.

As climate change puts tremendous stress on water resources by driving the monsoon erratic and accelerating the Himalaya glacier melting rate, Nepal´s community forest users, as in Hapur village, are exploring their own ways to cope with the looming water crisis.

Community forest users are building canals, ponds, reservoirs and better managing watersheds. Under the government´s ambitious Multi -Stakeholder Forestry Program (MSFP), supported by the governments of the UK, Finland and Switzerland, community forest users are getting support to identify their climate-induced problems and solve them.

“Ours is a bottom-up approach,” says Ramu Subedi, the MSFP team leader. “We encourage forest users to identify climate hazards and enable them to cope with them. We do not impose adaptation programs from the top.”

In its 2007 report, the United Nations (UN) panel on climate change has stated that water and its availability and quality will come under immense pressure in the wake of global temperature rise. What the UN panel states seems a reality in Nepal as well.

Forest users are now preparing Local Adaptation Plan of Action (LAPA), a village-specific document that helps the local communities adapt to the effects of climate change by identifying their climate hazards, along with their periodic operation plans. And, in most villages, water scarcity and irrigation problem appear to be the most common climate hazards.

“The severest stress of climate change is on our water resources — be it drinking water or irrigation,” says Subedi. “So, under the MSFP, we are helping local communities deal with these problems apart from mitigating the effects of climate change through forest conservation.”

Subedi adds, “Our National Adaptation Plan of Action (NAPA) document has identified 1.1 million households as vulnerable to climate change. We want reduce vulnerability of around 0.5 million households in a period of 10 years.”

In Hapur village, Chandra Jyoti CFUG allocated Rs 30,000 for the canal construction. Under the MSFP, the CFUG members got an assistance of Rs 50,000. The locals also made labor contribution worth about Rs 40,000.

“This project does not look big but effective enough to help the locals to adapt to climate change,” says Kul Bahaudr Lamichhane, a district committee member of the Federation of Community Forest Users Nepal (FECOFUN). “As in Hapur, forest users are coping with climate change by managing their water resource elsewhere as well.”

Nepal at risk as more extreme weather events loom

OM ASTHA RAI

KATHMANDU, Aug 25: The inhabitants of Surkhet, a district in Nepal´s mid-western region, were recently struck by what was arguably the worst flooding in living memory.

The death toll from the Surkhet flood, caused by the downpour that continued for two days in the second week of August, has reached 33, excluding 99 people still missing and thereby feared dead, so far, according to the National Emergency Operation Center (NEOC).

Around the same time, devastating floods struck other districts of the mid-western region like Bardiya and Dang, too. So, what led to such disastrous floods throughout the whole region? “Such a heavy downpour is unprecedented,” says Mahesh Gautam, president of Nepal Red Cross Society, Bardiya. “We had never before witnessed such intense rainfall.”

According to the Meteorological Forecasting Division (MFD), more than 150 mm of rainfall was recorded in eight different districts of the midwestern region during a short period of just 24 hours ending at 8:45 in the morning of August 15. In other regions of the country, no more than 100 mm rainfall was recorded during that same period.

“If 150 mm rainfall is recorded in some particular area in such a short period, we generally anticipate devastating flooding,” says Gautam. “But, in some places like Surkhet, even more than 400 mm of rainfall was recorded around that same time. It was something we never witnessed before. Even the elderly people in our community do not remember if they had witnessed such a heavy downpour before.”

The MFD officials say some rain data recorded in the midwestern region this year are record-making. Ever since it started keeping rain data in 1969, the MFD had never recorded 423 mm of rainfall in just 24 hours in Surkhet. Similarly, 298 mm of rainfall recorded in Dang during the same period is highest of all time. “Rains were intense this year in the midwestern region,” says Barun Poudel, a meteorologist at the MFD. “In our recent memory; we had not seen such an extreme weather event.”

Scientists say climate change causes extreme weather events, among other things. The term ´too much rain or too less rain´ is often used to explain the effects of climate change in the simplest way. The United Nations International Panel on Climate Change (IPCC) has unequivocally stated that climate change is already causing extreme weather events.

So, can the intense rainfall of the midwestern region be described as a result of climate change? “Theoretically, yes,” says Dr Arun Bhakta Shrestha, a senior climate change specialist at the International Center for Integrated Mountain Development (ICIMOD). “This is what climate change causes. But, we cannot say surely without proper research.”

Dr Shrestha says climate change increases frequency and magnitude of extreme weather events, meaning that Nepal could face in future more of what led to the devastating floods and landslides of the midwestern region. “It is a wake-up call,” says Dr Shrestha. “We now need to better mitigate climate change and better adapt to its effects.”

However, what happened in the midwestern region during and after the flooding has demonstrated that Nepal is yet unable to deal with disasters. When floods ravaged much of the region, early warning system collapsed, embankments gave way and government authorities fell short of resources to rehabilitate the displaced families.

In Bardiya, thousands of families living along the Babai River were confident that an early warning station set up to the north of their villages would alert them in case of a disastrous flood. But, the locals living south of Chepang village, where the station was placed to gauge the water level in the Babai River, had no inkling that the flood was about to wash away everything they had. The station failed right at the moment when it was needed the most.

“We had not anticipated such a worse flood in Babai,” says Rajendra Sharma, chief of Flood Forecasting Project at Department of Hydrology and Meteorology (DHM). “The very first wave of flood swept away our station; and people were caught unguarded.”

Gautam, the Bardiya Red Cross president, says, “We need better early warning system as climate change poses more serious threats of extreme weather events.”

Nepal’s disaster preparedness woefully inadequate

OM ASTHA RAI

KATHMANDU, Aug 21: Nepal has put in place plenty of plans, strategies and mechanisms to deal with disasters in the last five years.

But, is Nepal now well-prepared to manage disasters?

The answer is a big NO.

In the aftermath of the recent Sunkoshi landslide and other devastating floods, particularly in the plains of the midwestern region, it seems that Nepal´s disaster preparedness is almost non-existent.

Zero mitigation

Government officials often dub 2009 as a landmark year in the field of disaster risk management. On October 11 that year, the government approved a national strategy for disaster risk management, outlining top five priority areas.

In the years since 2009, several mechanisms, as envisioned by the national strategy, have been formed to manage disasters.

Water trapped by the August 2 landslide in the Sunkoshi River flows from two outlets dug in Mankha VDC of Sindhupalchowk district on Thursday. The water level in the trapped river had dropped by a meter and a half by Thursday. Nepal Army, which is involved in draining out the water, said it aims to reduce the water level by 15-20 meters. (Dhurva Dangal/Republica)

First of all, a consortium for disaster risk reduction was formed. The consortium, led by the home secretary, consists of development partners supporting Nepal´s disaster preparedness programs; and provides required financial and technical assistance.

Also, disaster response networks and search and rescue strategies have been prepared. The Ministry of Federal Affairs and Local Development (MoFALD) has also formed disaster management committees in many districts and villages.

So, despite all this preparedness, why did the recent floods cause so much damage in the mid-western region?

According to the National Emergency Operation Center (NEOC) of the Ministry of Home Affairs (MoHA), floods and landslides have killed 123 people, injured 67 people and left 126 people missing in several parts of the country since August 14.

In the same floods and landslides, 9,954 houses were completely damaged, 10,361 houses partially damaged, and 11,205 houses were inundated, and 20,245 families were displaced. Although the recent floods and landslides have hit as many as 25 districts, Surkhet, Dang and Bardiya are the worst affected ones.

Why did Nepal´s disaster management plans, programs, trategies and mechanisms fail to reduce the damages caused by the recent floods and landslides?

“Perhaps, our disaster preparedness is far from adequate,” says Ramesh Shrestha, an early warning system officer at Mercy Corps Nepal, an NGO working in disaster management sector.

Shrestha believes that there is no gap in disaster management policies and strategies but their implementation is far from satisfactory. “This is why disasters continue to cause so much destruction every year,” says Shrestha.

Ram Chandra Neupane, chairman of ECO-Nepal, another NGO working in disaster management sector, says, “In our plans, programs and strategies, we have focused on how to respond to disasters. But, we have failed to focus on how to mitigate risks of disasters.”

Neupane says mitigation is as important as responsiveness or even more so. “Unless mitigation is prioritized, response will always be insufficient,” says Neupane.

Constructing embankments along rivers is one of the most important aspects of mitigating the risk of floods. But, even flood-prone rivers are without embankments and flowing waywardly, killing people, damaging houses and displacing families every year.

This year, Babai River swelled up, changed its course and caused devastation in a vast area of fertile land – somewhere as far as five kilometers from the original water course. Although Babai is and was always a flood-prone river, the government has not built a strong embankment along its serpentine course so far.

Only a few months before the onset of monsoon, temporary embankments were built in some parts of Babai River, which were washed away by the flood. “Had there been a strong embankment along Babai River, damage would have been far less in Bardiya,” says Shrestha. “This is one area where our disaster management plans have failed.”

Poor response

Even in terms of responsiveness, Nepal does not look well-prepared. As part of Nepal´s flood forecasting project, nearly two dozen flood measurement stations have been set up. But, the recent floods showed these stations are too few and far between. In Babai River, the flood washed away the entire early warning system.

In the flood-ravaged villages, the displaced people have no place to sleep, no warm clothes to wear. They have been given rice. But, without kitchen utensils and fuelwood, they are unable to cook their meals. According to the NEOC, the government has distributed more than Rs 1.6 million as relief money to the flood victims. But, that seems too little.

“The recent floods and landslides showed that we are yet not prepared to deal with big disasters,” says Mahesh Gautam, president of Nepal Red Cross Society, Bardiya. “We need to go a long way in disaster preparedness sector.”

Sunkoshi tragedy exposes failure in hazard mapping

OM ASTHA RA

KATHMANDU, Aug 7: The landslide that killed more than 150 people and blocked the Sunkoshi River last Saturday at Mankha village of Sindhupalchowk district has exposed yawning gaps in Nepal´s hazard mapping and early warning mechanisms.

Hours before the dawn of August 2, a massive landslide occurred, creating a huge debris dam that completely blocked the course of the Sunkoshi River for over 12 hours. Only after a Nepal Army (NA) team created a channel through controlled explosions, some of the blocked water started flowing downward. However, almost a week later, the dam is still there, posing flood threats to people living downstream.

As per a report released by the International Center for Integrated Mountain Development (ICIMOD), a 1.9 km long slope of land perched 1,350 meters above the river bed collapsed in Jure area of Mankha village, burying around two dozen houses. Within the first three days of the disaster, rescuers recovered 33 dead bodies from under the rubble. On the fourth day, the government declared all 123 missing people dead.

Immediately after the Sunkoshi landslide, the government declared downstream villages along the river a flood emergency zone and evacuated more than 100 vulnerable families from the area. As days passed, normalcy seems to be slowly returning to downstream villages. With the NA team trying to release more water through controlled explosions, a lurking crisis seems to have been averted.

However, the Sunkoshi disaster could just be a wake-up call. If serous efforts are not undertaken, immediately, more such disasters could strike Nepali villages in future, say experts.

Haphazard settlements

In Larcha, a little village located between Tatopani and Fulping Katti VDCs of Sindhupalchowk, a massive landslide had occurred in 1996, sweeping away dozens of houses. However, the landslip-affected families resettled in the same village.

The Larcha landslide is a testimony to how hundreds of thousands of families are haphazardly living in flood and landslide prone villages. They are often struck by floods and landslides but continue to live there. Worse, the government has no plans and programs to identify flood and landslide prone villages and rehabilitate people from there.

Even in Jure, the hill where the Sunkoshi landslide occurred had collapsed around 60 years ago, according to Amrit Kumar Bohara, a CPN (UML) leader who witnessed the disaster when he was just a six-year-old child. But, the locals of Jure neither relocated to safer locations nor the government ever tried to evacuate them.

Suresh Nepal, who was Vice President of the Sindhupalchowk District Development Committee (DDC) when the Larcha landslide occurred, says, “People always want to live near the road even though there is constant fear of flooding and landslides. This is why the locals in Larcha and Jure did not move elsewhere even after being struck by landslides in the past.”

It is not just the locals who choose to overlook the threats of possible disasters. Even big companies have built hydropower plants fully knowing the risks of possible floods and landslides. Along the Sunkoshi (Bhotekoshi) River, there are at least three major hydro power plants apart from many other micro hydropower projects.

“Some people know the risks but are too poor to go elsewhere,” says Arun Bhakta Shrestha, a senior climate change specialist at the ICIMOD. “But, if you look at houses built along the Sunkoshi River, it would be hard to say that all the locals are poor and therefore incapable of moving elsewhere. In fact, they take calculated risks. So do hydropower companies.”

Risks can be reduced

The Sunkoshi river basin is vulnerable to Glacial Lake Outburst Floods (GLOF) and Landside Dam Outburst Floods (LDOFs). In the last 30 years, one GLOF and two LDOF events, excluding the August 2 tragedy, have already occurred in this region.

After a GLOF event in 1981, the level of the Araniko Highway was raised and taller bridges were built in an effort to minimize damages that future GLOF and LDOF events could cause. Beside, early warning system was set up by the Bhote Koshi hydropower plant.

What was done in the wake of the 1981 GLOF needs to be scaled up, say experts. They say hazard mapping and early warning system need to be developed not only in the Sunkoshi basin but across the country. “Although we cannot control natural hazards like landslides and floods, there are many things that can be done to minimize their adverse impact on lives, livelihoods, and valuable infrastructure,” says the ICIMOD report on the Sunkoshi landslide. “More efforts to map landslide risks are needed, and much more frequent monitoring of potential landslide sites is necessary.”

Can what the ICIMOD report recommends be done? “It is not a question of whether we can,” says Dr Shrestha. “We can and we must do it. If we cannot do it across the country at one once, let us start it from the most vulnerable village. But, let us do it right now.”

Combating climate change through forest conservation

OM ASTHA RAI

When he was a young farmer, Chandra Bir Kumal, a resident of Gobardiya village in Dang district, never had to rely on water stored in artificial reservoirs for rice plantation. He always used fresh water freely flowing through local streams.

“I do not know whether fresh water is better than stagnant water,” says Chandra Bir. “But, when I was active in farming, I never had to look for alternatives. I used to get a plenty of rainwater.”

Affectionately called by the local folks as Thula Ba (or the eldest villager), Chandra Bir is one of the first Kumals who settled in Banmari area of Gobardiya village. Later, many other Kumals, one of Nepal’s minority indigenous communities, settled down there. Today, the whole Banmari area is known as Kumal Gaun.

Later, many other Kumals, one of Nepal’s minority indigenous communities, settled down there. Today, the whole Banmari area is known as Kumal Gaun.

Nearly five decades ago, when Chandra Bir and a few other Kumal families started living in Banmara, chopping trees and fighting malaria, they did not have irrigation facilities. All they had was rainwater. And it was sufficient and reliable. “We did not need water reservoirs,” says he. “We did not even think of building them.”

However, as years passed by, rains started to get erratic. It became increasingly difficult to predict when monsoon would start and end. “It was not like this when I was young,” says Chandra Bir. “Then, the monsoon would normally start and end around the same time.”

As Chandra Bir aged and became too weak to work, his son Kalpa Ram, shouldered the burden of cultivating their eight kattha of farm land. But unlike in the time of his father, Kalpa Ram, now 50-year-old, did not find it easy to irrigate their farm land with rainwater. “If the monsoon arrives early this year, it gets late the next year,” says Kalpa Ram. “Rains are no longer predictable, no longer reliable.”

Fortunately, Kalpa Ram no longer needs to depend on just rainwater. He gets water supply for irrigation from a local pond. Built by a local Community Forest Users’ Group (CFUG), of which Kampa Ram is a member, this pond regularly supplies water to more than 200 families of Gobardiya village. “If this pond was not built, we all would have to leave this village a long ago,” says Kalpa Ram.

New wildfire soot variety could upset all global warming estimates

[http://www.natureasia.com/en/nindia/article/10.1038/nindia.2014.101]

Subhra Priyadarshini

Soot from wildfires across the world could actually be causing far more warming than our climate models account for. Hidden away from all scientific estimates is a newly-discovered form of soot – the ‘superaggregates’ – emitted from wildfires. Scientists have found that this kind of soot causes 90 per cent more warming than conventional sub-micrometer soot particles.

Current climate models make calculations of wildfire emissions based on sub-micrometer soot particles. The new findings suggest that if we were to reassess the warming from wildfires alone, the figure would go up many times.

The Nagarhole forest wildfire of 2012 that burnt thousands of acres to ashes.
WWT

The superaggregates came into light when scientists from the Desert Research Institute in Nevada-Reno, USA, were studying the massive 2012 wildfire in the Nagarhole National Forest of Karnataka. Studying aerosol samples over the Indian Ocean at the Maldives Climate Observatory on Hanimaadhoo Island, they found a new type of soot particle almost 10 times longer than normal and far more compact in shape than the sub-microscopic variety.

“We call these particles superaggregates because of their super-micron size. Conventional soot particles from diesel vehicles, cook stoves and other ‘contained’ combustion sources are sub-micron size aggregates,” one of the lead researchers Rajan Chakrabarty, presently a faculty member at the Washington University in St. Louis told Nature India.
Though ten times longer than conventional aggregates, the superaggregates have similar mass density. “This means although larger in size, these superaggregates can remain aloft in the atmosphere for the same lifespan (approximately a week) as conventional aggregates,” Chakrabarty said. This also means they get deposited on human lungs the very same way as conventional particles.
According to the scientists, the superaggregate form of soot has not been observed from wildfires before this study.
When they analysed the radiative properties, the scientists found that compared to spherical soot particles, these superaggregates could lead to 90% more warming in the atmosphere.
After detecting soot superaggregates from the 2012 Nagarhole sanctuary fire, the scientists went back to look at smoke samples from the 2010 Millerton Lake fire in Northern California, the 2011 Las Conchas fire in New Mexico, and some more wildfires near Mexico City. Not surprisingly, they found superaggregates in those samples too.
The scientists say though wildfires contribute significantly to global soot emissions, their aerosol formation mechanisms and particle properties are poorly represented in climate models. Superaggregates – previously unrecognized pollutants – could have considerable impact on climate and human health, they add.
“The higher heating effect of these particles, compared to volume-equivalent spheres, could change current estimates of climate forcing by models,” Chakrabarty added. He said multi-front future research in this area could lead to development of mechanical filtration systems to control public health impacts of soot superaggregates during large-scale wildfires.

Extra-terrestrial solar event triggered Uttarakhand cloudburst

[http://www.natureasia.com/en/nindia/article/10.1038/nindia.2014.98]

Subhra Priyadarshini

Unplanned human activities in the Himalayan terrain coupled with some unusual extra-terrestrial events triggered the massive cloudburst over Kedarnath resulting in the catastrophic 2013 floods in Uttarakand region of India, according to new research.

Using NASA satellite data, Saumitra Mukherjee from the School of Environmental Sciences at New Delhi’s Jawaharlal Nehru University (JNU) suggests that a sudden rise in ‘proton flux’ from the Sun was responsible for the catastrophe. The change in land use pattern (such as construction of reservoirs on the Ganges and Alaknanda rivers) added fuel to fire and created havoc in Uttarakhand.
“The rise in proton flux – an unusual solar event where protons emitted by the Sun are accelerated to very high energies – was responsible for the anomalous rise in atmospheric temperature. High concentration of aerosol trapped in the atmosphere and glaciers in Indo-China border initiated a nucleation process in the concentrated water vapour to trigger formation of clouds for the torrential rain and cloud burst on 16 and 17 June 2013,” Mukherjee told Nature India.

JNU

NASA’s Sun Observatory Heliospheric Observatory (SOHO) satellite recorded a steep rise in solar proton flux above 10 MeV for 12 days from May 15 to 26). During the same period, the cosmic ray intensity was also recorded at an all-time high at New Delhi’s Jawaharlal Nehru University (JNU), which represents the regional cosmic ray data in the Space Environment Viewing and Analysis Network (SEVAN) of the Asian office of Aerospace Research.

This was just before the anomalous rise in atmospheric temperature in the Himalayan region, which Mukherjee says was initiated by the release of heat energy from the trapped proton drift. “After this event anomalous rise in cosmic ray was recorded. Rise in cosmic rays was instrumental in condensation of the clouds leading to the cloudburst in Kedarnath,” he explains.
The scientist suggests that it took 20 days and 6 hours for the mechanism (of heat transfer to cloud appearance) to initiate the cloudburst in Kedarnath. The heat from the Sun was captured in the ‘Van Allen’s belt’ (between the Sun and Earth), which further accelerated the protons. This extra-terrestrial influence led to rise in temperature to release the aerosol trapped in the glaciers and atmosphere in the Indo-China border to initiate the cloudburst.
Generally, increase in aerosol heating over the Indo-Gangatic plains in the pre-monsoon period leads to a strengthening of the Indian monsoon. The heat transfer from the protons to the atmosphere has affected not only the atmospheric water vapour but has been responsible for melting of glaciers which feed the river Ganges.
Mukherjee says the influence of the Sun, along with anthropogenic activities, on climate change needs more study, especially its manifestation in torrential rains. “This is a radical departure from previous principles but is consistent with existing observations,” he adds.  Mukherjee says his hypothesis does not change the general conclusion that increased proton flux from the Sun reserves trapped heat in geospecific locations which influence temporary change in the atmosphere.
The Kedarnath extreme weather event is a clear manifestation of climate change, he adds.
The devastating flood in Uttarakhand in was a combined impact of cloudburst in Uttarakhand, quick melting of glaciers at high altitude due to beating of ice sheet by raindrops and breaching of natural embankment of Chorabari Tal (north of Kedarnath) due to accumulation of excess surface runoff. Within 48 hours, 280 mm rainfall was recorded and about five feet of snow precipitated at higher altitudes.
Apart from Uttarakhand, Himachal Pradesh, northeast Rajasthan and Delhi also received torrential rainfall. In Delhi, it was an advent of early monsoon that broke the past record of 150 years.
