Where the big rivers are
The biggest river deltas are flat and that’s why the cities which occupy some of the have expanded so much, so quickly. The last 50 years has seen a big population expansion on deltas – cities like Dhaka in Bangladesh. Twelve megacities on deltas have expanded in terms of populations from 62 million in 1975 to 153 million in 2010, an expansion that is not slowing.
‘Global Change’, which is the magazine of the International Geosphere Biosphere Programme (IGBP), has brought out a special number of deltas and the risks borne by city administrations that occupy deltas. The IGBP, in its own words, “coordinates international research on global-scale and regional-scale interactions between the Earth’s biological, chemical and physical processes, and their interactions with human systems”.
Flooding both from rivers and the sea is increasing. There was a storm surge in the Irrawaddy in Myanmar in 2008 when 200,000 people were killed. But people are still living on the delta. However, the estimate is that two million people have left the Indus delta in Pakistan to move to higher ground as salt water has invaded the farming zone. [A larger version of the graphic above can be found here (1.4MB). The original IGBP infographic which I have modified can be found here – caution, big file (12.7MB)].
The Po delta (near Venice in Italy) subsided largely because methane was being pumped from underground. They stopped the pumping and the delta is sinking 10 times less fast than it was. But the land surface is not actually rising, and it’s still below sea level. The Chao Phraya River Delta (along which Bangkok is built) subsided because of groundwater being pumped out to supply Thailand’s thirsty capital. So they introduced a tax on water use, such as showers. In Shanghai, the local government slowed the rate of pumping water out of the ground.
However, when countries set up commissions to look at the natural environment, it’s often water/river courses they’re concerned about, like with the Rhine. There is not so much focus on the delta. Where countries have tried geo-engineering, they can scarcely bear the prohibitive costs. It is estimated that China in the 15th to 18th centuries used 12-15% of its historical GDP in attempts to control the Yellow River from spilling out into its floodplain, but these gigantic efforts were never really successful.
Pakistan, India and people’s responsibility
For a month the government of India, aided by its media and propaganda units (urban-centric English language dailies and magazines, and a dangerously partisan group of television channels) has bombarded the Indian public with its view of Pakistan.
This is a view that is full of threat and anger. There is in no communication of the government of India (not from the office of the prime minister of India, not from the cabinet, not from Parliament, not from its major ministries which share concerns, such as water and food, and not from its paid servants, a wastrel gaggle of self-important think-tanks) that says, in effect, yes we understand the troubles your peoples have, for we have the same, and let us find ways to aid one another.
There is plenty of reason to do so.
Let us look first at floods and natural disasters, which India has a great deal of experience in dealing with, both through those government agencies that possess an iota of integrity and through voluntary groups and NGOs. Hundreds of thousands of people displaced by September monsoon flooding in Pakistan have not yet moved back into their homes, according to aid groups. Three of Pakistan’s four provinces were hit, affecting over 4.8 million people and damaging over 630,000 houses, according to the latest situation report by the National Disaster Management Authority (NDMA).

Humanitarian Snapshot Pakistan – Complex Emergency and Floods 2012 (as of 18 December 2012). The 2012 monsoon floods affected 4.8 million people, according to the National Disaster Management Authority (NDMA). Western Balochistan, southern Punjab and northern Sindh provinces were the worst affected. As of 18 December, more than 774,594 people remain displaced in Khyber Pakhtunkhwa due to a complex emergency that has affected region since 2008. Moreover, 1.7 million refugees require assistance as do many of the 1.3 million people who returned to FATA since 2010. Source: UNOCHA
Three months after the floods, 97 percent of those displaced have returned to their towns and villages. Nearly all of them, however, continue to live in makeshift shelters next to damaged homes. Aid groups and government officials say they still need critical assistance to help them through the winter. In the absence of adequate shelter and provisions, aid workers say, the cold weather in flood-hit areas is likely to put the affected population under more stress.

Next is the matter of population, economic support for a growing population and sustainable alternatives to the ‘growth is best’ nonsense that South Asian ruling cliques foster with the help of their industrialist compradors. Internal pressures in the country with the world’s sixth largest population are likely to get worse before they get better: At 2.03 percent Pakistan has the highest population growth rate in South Asia, and its total fertility rate, or the number of children born per woman, is also the highest in the region, at 3.5 percent. By 2030, the government projects that Pakistan’s population will exceed 242 million.
“The failure to adequately manage demographic growth puts further pressure on the current population, who already lack widespread basic services and social development,” said the IRIN analysis. Pakistan’s health and education infrastructures are poorly funded, and experts have questioned the quality of what is being provided with existing budgets. With a weak economy and low growth, food insecurity and unemployment present further challenges. “The problem is that if you have a population that is illiterate and does not have proper training, a large segment cannot participate meaningfully in the economy,” IRIN quoted economist Shahid Kardar, a former governor of the State Bank of Pakistan, as having said.

And then there is the very worrisome aspect of violence, against the poor and vulnerable as much as against women. I find it a macabre coincidence that during the weeks when polio workers in Pakistan were being shot at and killed, women in various parts of India were being gang-raped and murdered.
Over the past few weeks there has been an upsurge in attacks on aid workers in Pakistan, many of them linked to a national polio eradication campaign in one of the world’s last three countries where the disease remains endemic. In December 2012 the UN Children’s Fund (UNICEF) and the World Health Organization (WHO) suspended their anti-polio vaccination campaign after nine workers were killed in attacks in Karachi and Khyber-Pakhtunkhwa.
Polio workers, including those working for the UN, were also targeted earlier in 2012. Beyond the polio campaign, aid workers in general are starting to feel more hostility to their work. In an attack on 5 January, two aid workers with Al-Khidmat Foundation, an NGO working in education, were shot dead in the northwestern city of Charsadda. There was similarly no warning when gunmen killed seven aid workers with local NGO Support With Working Solution (SWWS) in the Swabi District of Pakistan’s Khyber-Pakhtunkhwa (KP) Province on 1 January.
And still the same old tiresome drums continued to beat, as they still do, Look at the reactions from India (and the jingoistic treatment given them by a rabid media):
India Today – “Military encounter on the LoC last week is threatening to erode the hard-fought gains in relaxing trade and visa regimes by India and Pakistan in recent times. The rhetoric is shrill in India, which claims it has been grievously wronged.”
Economic Times – “India has ruled out high-level talks with Pakistan to de-escalate hostilities and normalise bilateral relations, people familiar with the situation said. The position is in line with Prime Minister Manmohan Singh’s statement…”
Times of India – “India will maintain a tough outlook on Pakistan even as the LoC quietened after a fortnight of bruising skirmishes. At a meeting of the Cabinet Committee on Security (CCS) on Thursday, it was agreed that India would not respond immediately…”
BBC – “India’s foreign minister says he will “not rush” into talks with his Pakistani counterpart to defuse military tensions in Kashmir. Salman Khurshid’s remarks came after Hina Rabbani Khar’s call for a dialogue between the two ministers.”
DNA – “India’s army chief threatened to retaliate against Pakistan for the killing of two soldiers in fighting near the border of the disputed region of Kashmir, saying he had asked his commanders there to be aggressive in the face of provocation.”
Lost altogether in this teeth-gnashing mêlée of trouble-making are the efforts made by Pakistani and Indian people, such as the India Pakistan Soldiers Initiative (IPSI) for peace when they met at the Pakistan Red Crescent Society offices in Pakistan. Peace between the peoples of Pakistan and India that has nothing to do with the red-eyed posturing over the Line of Control and over Jammu and Kashmir will be our own responsibility.
How Britain went from drought to flood in three months
Britain has experienced a dramatic change in weather over the last three months, during which period ‘hosepipe bans’ and drought have been replaced by widespread flooding and steady rain. The droughts were compounded by a lack of rainfall over previous years, leading to empty reservoirs and lower river flows.

In this pair of maps, rainfall in March 2012 (left) had some areas in Britain seeing less than a fifth of the expected rain. April then saw nearly twice the expected rainfall for that month compared to average rainfall from 1971 to 2000. In June 2012 (right), most of the country experienced more than twice the expected rainfall. Graphics: The Telegraph / the Met Office – UK’s National Weather Service
Will it or won’t it? India’s monsoon forecast gamble
The India Meteorological Department (IMD) has released the long-awaited update of its long range forecast for the 2012 monsoon.
Stripped of its scientific jargon, this is what the update has said. There is a July model and an August model. For both months, there are three forecast categories: below normal in which rainfall in less than 94% of the long period average (LPA), normal in which the rainfall is between 94% and 106% of the LPA, and above normal in which rainfall is more than 106% of the LPA. Under the three categories, the forecast probabilities for July are (in the same order) 36%, 41% and 23% and for August they are 42%, 36% and 22%. Under any combination of probability therefore, this means that both July and August are going to be drier than usual, and coming on top of an unusually dry June, the scenarios for water availability and for agriculture come early September are all looking tough.
The volatility of the 2012 monsoon over north-eastern India can be seen in the images of the district weekly rainfall deviations for those states. Please bear in mind that with the late beginning of the 2012 monsoon, the week of June from 07 to 13 was for all practical purposes the first monsoon week. The colours signify major deviations – red for 50% of the average and below, green for 150% of the average and above. In Arunachal Pradesh, for the first week the average rainfall in districts was around 45%, the second week it was 41% and the third week it shot up to 124% – red is evenly scattered through the districts in the first two weeks and green districts appear in the third week.
In Assam, the first week’s average for all the state’s districts was 65% of the long period average, with red dominating. In the second week the average was 103%, with ‘red’ districts declining and a few greens appearing. In the third week the average zoomed to 184% with most districts being ‘green’. In neighbouring Meghalaya, the average for the districts in the three weeks was 63%, then 51% and then a steep rise to 225% in the third week. In stark contrast Nagaland and Manipur have for the duration of these three weeks seen a combined district rainfall average of 33% and if we remove the ‘green’ districts from both states of the third week, we get a dismal 15% average – it is of course quite likely that there are data anomalies in the numbers that IMD has collected from the north-east region, as automated weather stations that actually work are likely to be fewer in number than in ‘mainland’ India. (There is a spreadsheet for this data. If you want the data till date please write to me here: makanaka at pobox dot com.)

In the update, there is also a separate set of forecasts and probabilities for four major regions of India – North-West India, Central India, South Peninsula and North-East India. There are small variations for each of these in the definitions of below normal, normal and above normal. Here are the forecast probabilities for the regions:
The list of states in each of these four geographical regions is:
Northwest India: Jammu and Kashmir, Himachal Pradesh, Punjab, Rajasthan, Haryana, Chandigarh, Delhi, Uttaranchal and Uttar Pradesh.
Northeast India: Arunachal Pradesh, Meghalaya, Assam, Nagaland, Manipur, Mizoram, Tripura, Sikkim, West Bengal, Bihar and Jharkhand.
Central India: Gujarat, Madhya Pradesh, Chattisgarh, Maharashtra, Goa and Orissa.
South Peninsula: Andhra Pradesh, Karnataka, Tamil Nadu, Kerala, Lakshadweep and Andaman and Nicobar Islands.

The first stage forecast for the nation-wide season rainfall was issued on 2012 April 26 and this update was issued on 2012 June 22. The summary of the first stage forecast is:
“Southwest monsoon seasonal rainfall for the country as a whole is most likely to be Normal (96-104% of Long Period Average (LPA)) with the probability of 47%. The probability (24%) of season rainfall to be below normal (90-96% of LPA) is also higher than its climatological value. However, the probability of season rainfall to be deficient (below 90% of LPA) or excess (above 110% of LPA) is relatively low (less than 10%). Quantitatively, monsoon season rainfall is likely to be 99% of the LPA with a model error of ± 5%. The LPA of the season rainfall over the country as a whole for the period 1951-2000 is 89 cm.”
The IMD has said that it has taken into account the experimental forecasts prepared by the national institutes like Space Applications Centre, Ahmedabad, Centre for Mathematical Modeling and Computer Simulation, Bangalore, Center for Development of Advanced Computing, Pune and Indian Institute of Tropical Meteorology, Pune. Operational/experimental forecasts prepared by international institutes like the National Centers for Environmental Prediction, USA, International Research Institute for Climate and Society, USA, Meteorological Office, UK, Meteo France, the European Center for Medium Range Weather Forecasts, UK, Japan Meteorological Agency, Japan Agency for Marine-Earth Science and Technology, Asian-Pacific Economic Cooperation (APEC) Climate Centre, Korea and World Meteorological Organization’s Lead Centre for Long Range Forecasting – Multi-Model Ensemble have also been taken into account.
Floods in Pakistan displace 5.4 million

Torrential monsoon rains have triggered severe flooding in Pakistan, primarily in Sindh Province, Reliefweb has reported. Before the monsoon season began, forecasts predicted 10% below normal rains for Sindh and the southern parts of the country for the 2011 monsoon season. However, by 10 August, heavy rains began affecting districts of southern Sindh and extended to the northern regions of the province and adjoining areas of south Punjab and north-eastern Balochistan. While this spell lasted till mid-August, another more debilitating and sustained rain spell heavily affected areas across the entire Sindh Province from the end of August until 14 September. Concurrent impact in adjoining vast areas of Balochistan has resulted in serious humanitarian consequences including in South Punjab. In Sindh, the central and southern districts have been the worst affected.
These rains caused widespread breaches in the agricultural and saline water canals, particularly in the Left Bank Outfall Drain, which exacerbated flood impact in Badin, Mirpurkhas and Tharparkar districts, among others. Continued rains have seriously impeded delivery of emergency services and flood impacted mitigation works. Outflow of the draining flood water is compromised due to poor infrastructure and lack of maintenance of the drainage routes. Some parts of Karachi and Hyderabad have also experienced urban flooding. Flood waters are likely to stagnate in most of the affected regions for the foreseeable future.
As the monsoon season continues, the impact upon the population is intensifying with 5.4 million people affected to date. In Sindh, in particular, the concentration is most severe and all 23 districts have been affected to some degree. It is expected that the population will continue to be uprooted from their homes to seek refuge in the short term as more areas are affected. While some are housed in Government appointed shelters, more seek higher ground along bunds and roads. In Balochistan, five districts are affected and notified (considered seriously affected by the national authorities).The Government of Pakistan, through the National Disaster Management Authority (NDMA) and utilising the Armed Forces’ logistical capacity, has taken the lead in responding to the disaster with the deployment of rescue and life-saving relief operations.
IRIN News has reported that heavy monsoon rain in southern Pakistan is in many ways hitting children worst of all, according to the UN Office for the Coordination of Humanitarian Affairs, which says five million people are affected. The UN Children’s Fund (UNICEF) says children are among the most vulnerable in the kind of situation that prevails now in Sindh Province: “Up to 2.5 million children have been affected by severe monsoon floods in southern Pakistan – and with many still recovering from the worst floods in the country’s history just a year ago, UNICEF says more help must reach them fast before the situation worsens.”
Media in Pakistan quoted disaster management authorities in Sindh as saying at least 270 people have been killed in the province’s 23 districts. The provincial government, which has called on international agencies to help, says 1.2 million homes have been washed away, while the aid agency Oxfam has reported that more than 4.2 million acres of land (1,699,680 hectares) has been flooded and 1.59 million acres (643,450 hectares) of standing crops destroyed in Sindh. It also warned the “situation could worsen” over the coming days.
“The nature of this disaster in some ways poses challenges that are more complex than those of 2010,” Kristen Elsby, a spokesperson for UNICEF, told IRIN from Islamabad. She said the main factor in this was that displaced populations were scattered, with many based along roadsides. “We did not know where to go when the rains swept in, took away our goats and destroyed the vegetable crop we had cultivated,” said Azrah Bibi from Badin District. She and her extended family of eight are currently camped along a roadside near the town of Badin. “We saw some people here and joined them. Some people delivered one lot of food, but there has been very little since, and it is hard to cook anyway since we have no facilities other than a fire from bits of timber and scrap,” she said.

“Children, in particular, need access to clean water and also sanitation to prevent illness from breaking out.” Like many others affected by this year’s flood, Azrah Bibi and her husband, Gulab Din, 45, were also affected by the floods of 2010, widely rated as the worst in the country’s history, which partially damaged their home and also their rice crop. “This year things seem equally bad to me. The wrath of Allah has hit us twice,” she said.
Another IRIN report has said that Sindh is facing disaster once more with heavy rains over the past five days, according to the Provincial Disaster Management Authority (PDMA). “Two million people in 15 [out of 23] districts have been affected,” PDMA Director of Operations Sajjad Haider told IRIN. He also said crops had been devastated. Eighty-five people are reported to have died and provincial authorities have announced disaster relief measures, including compensation packages for victims. Haider said crops had been devastated.
“My sugarcane crop, which was ready for harvesting, has been lost. I am still recovering from last year’s losses of crops and livestock. Who knows what will happen now,” said Majeed-ud-Din, 40, from his village in Khairpur, one of the worst-hit districts. In the remote Kohistan District of Khyber Pakhtoonkhwa Province (KP) flash floods triggered by heavy rain last week are now confirmed by District Coordination Officer Syed Imtiaz Ali Shah as having killed at least 33 people. Media reports put the death toll at almost double that figure, with dozens of houses including an entire village swept away by torrents pouring down hillsides.
[See the earlier post, ‘Pakistan floods six months later’]
The UN Rapid Response Plan has said that in Sindh, of the approximately 5.44 million people affected, 49% are women. The number of deaths has increased to 223, of which 60 are women and 37 are children. To date, 665,821 family homes have been damaged or destroyed. Nearly 297,041 people (77,175 women, 139,661 children) are currently living in 2,150 relief sites.
The situation of the people who have been forced to leave their homes is dire, and there is clear evidence of growing humanitarian needs. People have sought refuge on higher ground, along roadsides and on bunds, while others are housed in public shelters. Access to safe drinking water is compromised, although health services are reaching out. Due to damaged infrastructure, however, it is difficult for the population to access existing services and efforts to avoid a major disease outbreak must continue. With an increasing number of people uprooted as a consequence of the situation, ensuring emergency shelter and food for the population is critical.
Across both provinces, Sindh and Balochistan, there has been a significant impact on people’s lives, especially related to the loss of livelihoods, most predominantly those related to agricultural activities. The UN Rapid Response Plan has said that approximately 80% of Sindh’s rural population’s livelihood is dependent upon agricultural activities, such as crops, livestock, fisheries and forestry. According to preliminary information from NDMA, 1.6 million acres of crop area have been destroyed by the floods, and pre-harvest crop losses include rice, vegetables, cotton, and sugarcane. The survival and health of animals in flood-affected areas are at risk due to loss of fodder reserves and animal feeds. These combined effects are likely to severely affect the availability of and access to adequate food for a large proportion of the affected population over the coming months.
The floodwaters have devastated towns and villages, washed away access routes, downed power and communications lines, and inflicted major damage to buildings. Many key roads and major bridges are damaged or destroyed. The prevailing socio-economic conditions along with flood have exacerbated the living conditions of women, men, boys and girls residing in the flood-affected districts. Additionally, female and children are not always able to access basic services or humanitarian aid. Vulnerable people in general are potentially experiencing a higher risk of disease, in addition to the challenges of limited access and mobility.
Bangladesh adapts to climate change – watch ‘Afloat’
Most of Bangladesh is a giant delta lying in a cyclone ‘hotspot’. As these stupendous storms become fiercer and more frequent and sea level inexorably rises, flooding has become the norm in many parts of the country. The soil becomes salty, crops wash away, homes disappear.
In Bangladesh, climate change is a humanitarian crisis in the here and now. But millions in this beleaguered country are learning to stay one step ahead of the changes caused by a climate off kilter. Using a very modern mix of tradition and innovation, they are learning to adapt to an increasingly unpredictable new world.

Sri Lanka floods: ‘We don’t have a harvest’
Sri Lanka will lose over one million tons from its upcoming paddy harvest due to recent flooding, officials have told IRIN news. “We expected a yield of around 2.75 million metric tons from the harvest due in March to April,” Kulugammanne Karunathileke, secretary to the Ministry of Agriculture, told IRIN. “After the heavy rains we will only get around 1.75 million.”
Karunathileke, the highest ranking official at the ministry, said the country had expected a bumper crop – until flooding, which began in January, left some paddy fields under water for up to 11 days. The worst-hit areas are in the eastern districts of Ampara, Batticaloa, Polonnaruwa, Trincomalee and the north-central district of Anuradhapura. Together they account for over 1.2m tons of the harvest. Of the over 700,000 hectares cultivated this season, more than 200,000 have been destroyed, Karunathileke said.
Early this month, over a million Sri Lankans were affected by some of the worst flooding the country has seen in decades, reported AlertNet. Some regions in the country’s east, such as Batticaloa, received over 300 mm of rain within 24 hours, the highest daily rainfall in almost a century. But experts warn that Sri Lankans had better get used to such extreme weather conditions as the island adjusts to changing global climatic conditions.
“Global weather patterns are changing and we have to be aware of that,” warned Gunavi Samarasinghe, the head of the country’s metrological department. Since June 2009, Sri Lanka has dealt with four large floods that have affected over two million people. Among rural villagers like Heenbanda, living almost 250 km from the capital Colombo in the remote Polonnaruwa District, however, there is hardly any knowledge about global climate change or how best to face it.
“We don’t know how it happened. We don’t know why,” Heenbanda said. “We only know that we don’t have a harvest this time.” The raging floods inundated rice paddy land in Sri Lanka’s four eastern districts of Polonnaruwa, Batticaloa, Trincomalee and Ampara, areas that account for over a fifth of the country’s rice production. According to the U.N. Food and Agriculture Organization, at least 15.5 percent of the main annual rice harvest, due in March and valued at $120 million, could be lost.
