Pakistan needs to improve its floodplain management, consider water conservation and focus on harnessing the power of excessive rains to solve its water crisis, said experts at a ceremony in Islamabad on Wednesday.

The ceremony was organised by the Ministry of Climate Change (MoCC) in collaboration with the World Wildlife Fund (WWF) Pakistan to mark the International Day of Biological Diversity 2013, celebrated annually on May 22. The theme for this year was “Water and Biodiversity.” Interestingly, the United Nations has also marked 2013 as the International Year of Water Cooperation.

Speakers stated that floodplain management incorporates limiting the level of flooding to protect natural habitat and wildlife by ensuring effective flood control regulations and finding ways to protect communities residing in flood-prone areas.

A ‘floodplain’ is an area, bordering a river, which floods with superfluous water from the rivers during flooding season, explained Dr Masood Arshad, senior programme manager of the WWF-Pakistan, to the audience.

Arshad said the British built embankments around rivers in present-day Pakistan to protect adjoining settled areas from excess water, but this model failed to serve its purpose during the 2010 floods. He shared the recommendations of the Ramsar Advisory Mission (RAM) which visited Pakistan in 2012 to study the impact of the 2010 floods and offer suggestions for flood mitigation.

The RAM is an international technical assistance body for resolving problems related to wetlands.

The mission recommended soft engineering solutions to be integrated in the floods management mechanism in addition to “hard engineering” flood responses such as construction of dams and solid embankments.

The soft solutions include restoring the natural flood storage capacity of the floodplain by removing illegal structures and constraining embankments from the floodplains, said Mehmood Nasir, the Inspector General of Forestry at the MoCC. This would allow the passage of high flows during flooding season, he said.

Nasir said China had deployed a similar model successfully to control annual flooding in the Yangtze River.

“We should widen the path of the river’s flow and allow the flood water to spread into the floodplains,” he said. “The excess water will recharge aquifers, replenish underground water reservoirs and even help restore lakes that have become poisonous.”

Nasir suggested Pakistan to look at floods as a “blessing” rather than as a catastrophe and floodplain management should be made a substantial part of the disaster management policy.

The RAM also identified pilot project sites for diverting flood water and maintaining natural flows to the Arabian Sea so as to prevent sea intrusion.

Gul Najam Jamy, the assistant country director of the United Nations Development Programme (UNDP), said Pakistan was a water stressed country where the per capita water availability is decreasing.

Admonishing Pakistan’s national culture of excessive and inefficient water usage, Jamy cited the common practice of flash-flooding of rice paddies by farmers and leakage of water in supply systems.

“Just because we think we have a grand plan to build a big national dam, we shun our daily responsibilities to save water,” he said.

He said governments should take up water harvesting and individuals should also contribute to conserving water resources.

Kowkab Iqbal, a lawyer in Islamabad, said people should be made aware about presence of Green Benches in High Courts so they can move cases against environmental degradations, especially water pollution-related issues.

Children from the Mashal Model School — a welfare learning institute in Nurpur Shahan for underprivileged children — presented a tableau depicting the way human activities such as industrialisation and urbanisation have adversely affected biodiversity and water resources.

The most economical way to store water is not dams as there is evaporation loss and other issues the best solution is store rain and surface water runoff is underground storage and use it when needed. But water will not store on its own we need to give flood water enough time and space to percolate. To give time for seepage we must have trees and enough space for flood water to spread. RAM mission is a wonderful work and innovative. There is a need for the Ministry and all NGOs hunting for water funds to meet and devise ways on how to implement RAM recommendations and see that can be replicated form the Chinese experiences of the Ynagtze river

Many agencies are working on water issues and trying to re-discover whatever is already there, all have hired consultants who have to find good words. Floodplain management is a new issue worldwide after the Chinese have shown that it works well to drain polluted lakes and restore ground water that provides water to many cities of the world. So is the role of forests and trees very important, if there is no forest there will be no water to drink or stores in the dams
