AGWA Launches Toolkit for Climate Change Adaptation in Water Resources Management

---

4 September 2014: The Alliance for Global Water Adaptation (AGWA) and partners have launched a manual for dealing with uncertainty under climate change by applying climate-informed decision-making to water resource management, project design and risk evaluation.

The manual was launched in a seminar held during World Water Week, on 4 September.

‘Beyond Downscaling: A Bottom-Up Approach to Climate Adaptation for Water Resources Management' is the result of two years' work by AGWA, the World Bank, the Inter-American Development Bank (IDB), US Army Corps of Engineers, University of Massachusetts and RTI International, among others.

It provides practical guidelines for practitioners and project coordinators for risk-based decision making and adaptation of water systems by using a bottom-up approach. The book aims to “provide an alternative approach contributing to improvement in the quality and effectiveness of water resources management planning and project design under climate variability and change uncertainty.”

The manual covers: AGWA's approach to sustainable water management; climate change impacts on water resources; mainstreaming adaptation into water resources management; key tools for supporting climate risk assessment; and approaches to identifying adaptation strategies for water projects. It also makes the case for moving beyond down-scaling global climate models, to a bottom-up approach to climate adaptation in the water sector, and presents a framework for an AGWA-supported adaptation approach.

The approach supported by AGWA, inter alia: recognizes the need to integrate climate adaptation into existing decision-making processes; advocates for bottom-up approaches to vulnerability assessment; supports the use of “systematic decision trees based on existing water resources management approaches”; stresses the importance of creating flexible decision pathways; and emphasizes the integration of flexible governance mechanisms into water resources management.

Speaking at the launch, Marcus Wijnen, Senior Water Resources Management Specialist, World Bank, noted that the book is “work in progress,” and invited stakeholders to provide feedback. More

Henan’s Big Drought. Is This From The South–North Water Transfer Project?

Mainland media reported that, since this summer, Henan Province rainfall is 60 percent less than usual over the same period since 1951, which is the lowest value over the same period of history. Pingdingshan City's main water source, Baiguishan reservoir water level is even lower than the dead water of 97.5 meters.

Henan Zhecheng County Shuangmiao Village Ms. Li, “over the entire summer it did not rain. The crops are dry. We are not allowed to irrigate the crops. If I use the well water, I probably cannot even have drinking water."

Droughts have had a serious impact on local agriculture.

Ms. Li, "most places basically have no harvest. Individual crops can be harvested a little, but there is not much. If one place can harvest 40 percent, that’s the best.''

Hubei Province is rich in water during the main flood season this year. But rainfall in most areas decreased by more than 20 percent. 111 small reservoirs and over 50,000 ponds dried up; over 600 reservoirs are below the dead water level; Hanjiang River downstream water level dropped. Danjiangkou reservoir water level is only 142.77 meters on August 19. This is far below the SNWTP planned water level of 170 meters.

For this major disaster, the authorities explained that the drought is caused by a variety of climatic reasons. They claimed that, even if the current trend of precipitation is "north flood south dry", it is still to "transfer water from south to north" to fill the gap of an especially severe water shortage in Beijing.

But the villagers in drought regions have different thoughts.

Ms. Li, " we all think it is due to the SNWTP. In previous years, it was not as dry as in these years."

Villagers discussed and believe that, SNWTP leads the Han River, the Yangtze River and the Yellow River water back and forth; the Three Gorges Reservoir also caused natural flowing rivers to change direction. Poor circulation, and loss of groundwater resources are also very serious. It has a massive impact not only to the surrounding geological environment, but also caused imbalances to the water, clouds, rain, and natural circulation system leading to a severe drought.

Living in Germany, water resources expert Wang Weiluo, has published many articles about Jiang Zemin who to "supply water to the 2008 Beijing Olympics", hastily approved and launched the SNWTP in 2001. It introduced one billion cubic meters of water annually to Beijing, with diversion channels crossing more than 700 natural rivers in Central China. The project completely

broke the law of nature of these rivers; There is a serious engineering problem, even bigger than the Three Gorges, and the threat is to a wider area.

Beijing electrical engineer Mr. Tian, "in principle there is a problem, because it is not that the south is high, the north is low, and it naturally flows across. It is to artificially add a number of processes, which undermines the law of nature. I think this may be even worse than the Three Gorges Dam."

Problems have been reported recently about SNWTP by the media. When the Diversion project tested the water on July 3 for the first time, the media exposed that the water source from Danjiangkou Reservoir exceeded the nitrogen content, and was seriously polluted. The official also acknowledged that water quality for nitrogen and phosphorus exceeded the standards. However he stressed that it would naturally degrade through long-distance transportation.

In late July, the mainland media also reported that SNWTP led to a decrease in the Han River water level. Due to the reduced water flow the fish were unable to spawn by end of July, while in previous years they had finished spawning. Yicheng city located by the Han River was without water three times since last year, the longest time was 48 hours.

In addition to the environmental damages, Beijing electrical engineer Mr. Tian pointed out that the drain from SNWTP is likely to outweigh the benefits.

Mr. Tian, "this unnatural process takes a lot of energy and wastes a lot of water. Introduce ten percent water, and finally arriving in Beijing, maybe even not two percent will get there."

SNWTP has three water diversion routes, namely the east, middle and west line. Of which the middle and east lines cost amounted to 500 billion yuan, 2.5 times larger than the Three Gorges Project. The East line is pumped from the Yangtze River to Tianjin, Qingdao and Yantai direction. The Midline is from Danjiangkou Reservoir as a division of Yangtze tributary the Han River, in Beijing’s direction; The West line is from the upper Yangtze River to the Yellow River water diversion. The East line started in December 2002, until December 8, 2013 the water went through. The Midline started in December 2003, is expected to have water through in October 2014. The West Line has not been started yet. More
