Summer break at Mouth to Source

Readers,

After two years, I’m taking a break on the beaches of Brittany with my family.

Back around the end of August to resume transmission from Phnom Penh.

Looking forward to refreshing my senses and some awesome ‘Chateau de Sable’ (sandcastle) action with my daughter. I have some very interesting Asian techniques I’ll be sharing with our French brothers and sisters.

I will NOT be available via e-mail so please keep any questions you may have for my return. I wish you all a very safe trip wherever you may be and look forward to coming back to shoot and present some new work for you all at Mouth to Source.

Wired Water: IT Gets Ready for the Shock

By Ned Madden | TechNewsWorld

IBM has jumped in fully clothed. Big Blue’s Big Green portfolio of smart water services and technologies uses advanced analytics developed by mathematicians in IBM’s labs, as well as the company’s information management, technology services, and business consulting capabilities.

To replace workers dispatched in trucks to check on water quality and levels and look for pipeline leaks and breaks, IBM automates the process with systems to monitor reservoirs, rivers and harbors, placing small sensors in the water and along pipelines right up to homes and businesses. Back-end software analyzes the resulting data and displays it on computer dashboards that enable water managers to monitor their systems and head off problems like leaks or contamination.

The IT giant, determined to expand beyond traditional computer services, is moving fast because it’s seeing Big Water just keep getting bigger. Revenues of the world’s water-related businesses will rise from $522 billion in 2007 to nearly $1 trillion by 2020, according to New York-based Lux Research. The firm’s April 2009 report “Water Cultivation: The Path to Profit in Meeting Water Needs” predicts that a world facing water shortages will need a new “water cultivation” approach characterized by efficiency, reuse and source diversification.

Tools like smart meters that limit lawn-watering to nighttime hours, or sensors that detect leaks in pipes, are just a few of many ways computers can help monitor water use, Lux senior analyst Michael LoCascio said. The real change must come in our mindset about the wet stuff.

“The world will avert crisis by cultivating water as a durable asset rather than throwing it away as a consumable — creating growth opportunities in everything from oxidizing new contaminants to rehabilitating creaking infrastructure,” LoCascio told TechNewsWorld.

Though computers have been used for decades in the large-scale mapping of ground and surface water sources, today’s water crisis has pushed the water industry toward computer automation solutions that range from the largest national and international projects down to the individual homeowner’s front yard.

Biodiversity helps feed poorest

Tuesday, 23 June 2009 | Charles Sturt University

Published in the latest issue of the international journal Conservation Letters, the research has implications for the employment of conservation and human development projects worldwide and for guiding investment decisions by global institutions such as the World Bank and World Wide Fund for Nature.

“The services we examined included providing water for drinking and agriculture and minimising the effects of flooding,” Professor Luck said.

“We found that these services were most needed in watersheds found in the world’s poorest and most densely populated regions. Some of these regions are also ‘rich’ in biodiversity and we identified Southeast Asia and East Africa as regions with the highest priorities for protecting nature’s services and biodiversity.

“Our research showed that a dollar spent protecting nature’s services in many developing countries would have a greater relative benefit to humans than spending the same amount in developed countries such as Australia and the USA.

“People living in developing countries rely heavily on the services provided by local forests, wetlands and other ecosystems. In developing countries, land is relatively cheap to acquire for conservation and restoration and labour costs are lower than developed countries. Many of these areas are also under greater threat from land clearing, undermining the capacity of nature to provide services.

Draining paddy fields could cut methane from rice production

From The Ecologist

The organic waste and lack of oxygen in water-covered paddy fields provide a fertile feeding ground for certain types of greenhouse-gas-producing bacteria. Global rice production accounts for as much as 25 million tonnes a year of methane.

But experts at the Chinese Academy of Science have found that draining rice paddies once during the growing season, as well as applying leftover ‘rice straw’ off-season, could cut methane emissions by 30 per cent (7.6 million tonnes).

‘Draining allows organic material to decompose aerobically as it is not covered by standing water,’ said lead scientist Yan Xiaoyuan of the Institute of Soil Science, Chinese Academy of Sciences.

Thousands Call for Regional Governments to Save the Mekong

Press Release from Save the Mekong coalition.

June 18, 2009

In a bold outpouring of public concern for Southeast Asia’s Mekong River, more than 16,000 people from within the six-country Mekong region and around the world have signed a “Save the Mekong” petition urging governments to abandon plans for hydropower development along the river’s mainstream. The petition - written in seven languages - will be hand-delivered to Thailand’s Prime Minister H.E. Abhisit Vejjajiva on 18 June in Bangkok, and sent to other government leaders within the region.

Despite strong government backing for dam building on the Mekong River, over 10,000 people from within the Mekong region have signed the petition addressed to the Prime Ministers of Cambodia, Lao PDR, Thailand and Vietnam urging them to keep the river flowing freely and to pursue less damaging electricity options. The petition is signed by fishers and farmers living along the river’s mainstream and tributaries, as well as by monks, students, city-folk and even some of the region’s well-known celebrities. Another 6,000 people around the world signed the postcards and an online petition.

Most postcard signatories wrote personal messages to the region’s leaders:

“Don’t let hydropower dams block our children’s future!” Wang Dezhi, Yunnan, China

“Don’t build the Mekong dams. The existing dams in Thailand already make brothers and sisters fight against each other!” Mak Vangdokmai, Roi et, Thailand

“I love my country. I don’t want to see some people destroy my home country for greed. So I would like to do my best to protect our Mekong!” Sneampay, Vientiane, Laos

“If the dams happen, where will all of us go to live?” Villager, Stung Treng province, Cambodia.

“Saving us, saving our resources! Electricity is not everything!” Nguyen Thanh Hang, Hanoi, Vietnam

“I have traveled the Mekong River from Laos to Thailand to Cambodia and dams will destroy the river, environment and tourism.” M. Higgs, London, England

In the lead-up to this week’s Save the Mekong launch, citizens groups have organized a number of events over the past few months to rally public support for the river:

* Bangkok’s Central World department store, Thailand, March 2009: An exhibition by award-winning Thai photographer Suthep Kritsanavarin highlighted the threat to Mekong fishing from the Don Sahong dam planned for Southern Lao PDR. The exhibition prompted thousands of Bangkokians to sign the petition postcard.

* Phnom Penh, Hun Sen Park, Cambodia, June 2009: A stall at the World Environment Week’s eco-festival in Phnom Penh highlighted the risks from the mainstream dams to Cambodia’s fisheries and urged hundreds of concerned citizens to add their signatures to the Save the Mekong on-line petition.

* Ubon Ratchathani province, Thailand, June 2009: Local groups, students, academics and photographers organized a series of public events, dubbed “the Mekong weeks”, and collected over 4,000 petition signatures. The events highlighted the value and natural beauty of the “Three Thousand Wells” stretch of the Mekong River, where it forms the border between northeast Thailand and Lao PDR. The area is an increasingly popular ecotourism destination that is now threatened by the proposed Ban Koum dam.

* Phnom Penh, Cambodia, June 2009 Local groups and fishing community leaders organized a national workshop about the importance of the Mekong’s fisheries for local livelihoods and the environment, and to discuss the food security impacts that the Don Sahong mainstream dam could have on Cambodians.

Mekong fisheries provide a critical source of food and income for millions of people along the river. Recent official estimates place the annual value of the river’s wild capture fisheries to be worth up to US$3 billion. Mainstream dams will block the massive fish migrations that count for up to 70% of the river’s commercial fish catch and that ensure regional food security. Experience around the world demonstrates that there is no way to mitigate the fisheries impacts of such large dams.

Civil society groups in the Mekong region and internationally have been sounding the alarm about plans to build eleven hydro dams on the Lower Mekong mainstream for many years, in what is often described as an uphill battle.

China’s dam construction on the Upper Mekong mainstream (Lancang) has already caused serious environmental problems, in the form of declining fish stocks, riverbank erosion, and hazardous water level fluctuations in downstream Burma, northern Thailand and northern Lao PDR. The Save the Mekong coalition and those that signed the petition are very concerned that similarly severe cross-border impacts could create cross-border disputes.

When meeting Prime Minister H.E. Abhisit Vejjajiva, the Save the Mekong coalition representatives will present him with the Save the Mekong petition and ask him to work with regional leaders to protect the Mekong River. Thai representatives will raise their concerns with the Prime Minister about the Thai-Laos Ban Koum and Pak Chom dams and ask for clarification on the government’s position on these projects.

Thailand’s Minister of Energy recently spent 60 million baht on a feasibility study for the Pak Chom dam and a feasibility study for the Ban Koum dam study has been prepared by Italian-Thai Company. In addition, in Lao PDR, Thailand’s Chor Khanchang company and Charoen Energy and Water Asia company are the lead developers of the Xayaboury and Lat Sua mainstream dams respectively. Much of the mainstream dams’ hydroelectricity is anticipated to feed into Thailand’s power grid.

The largely donor-backed inter-governmental Mekong River Commission, meanwhile, has failed to disclose its assessment of the Don Sahong dam, prepared in 2007, despite repeated requests from civil society groups, and is now positioning itself as a “facilitator” among the region’s hydro developers. The MRC has skirted some of the most critical issues, including on ensuring transparency and public participation, and protecting regional food security.

Despite the limited space for public debate, the Save the Mekong petition aims to make heard the people’s voices for protecting the Mekong as a giant food chain and cultural lifeline for millions of people.
