Stockholm, Aug 21 - Indian sanitation expert Bindeshwar Pathak was awarded the 2009 Stockholm Water Prize, the most prestigious award for outstanding achievement in water-related activities that has become akin to a Nobel Prize on environmental issues.

Sanitation is humanity's and the world's most urgent and critical crisis of our times,' Pathak told IANS and added: 'However, it is not, yet, an unsolvable crisis but a huge challenge. It will require massive, dedicated and selfless labour to achieve the goal.'

Pathak received the award Thursday from H.R.H. Prince Carl Philip of Sweden.

The Stockholm Water Prize, which was first presented in 1991, includes a $150,000 award and a crystal sculpture. It honours individuals, institutions or organisations whose work contributes broadly to the conservation and protection of water resources and improves the health of the planet's inhabitants and ecosystems.

'The correlation between sanitation and disease is dramatic and unmistakable,' said Anders Berntell, executive director of the Stockholm International Water Institute (SIWI).

'Yet, at the current rate of progress, we are going to miss the Millennium Development Goal for sanitation by more than 700 million people, leaving still 2.4 billion people without adequate sanitation by 2015, about the same number as today. By any standard, this is unacceptable. We need the political will to translate our intentions into meaningful action.'

In seminars, workshops, and side events during the week, participants have explored the causes, health impacts and possible solutions to inadequate sanitation that currently affects more than 2.6 billion people across the planet, kills over 5,000 children daily, and causes the illnesses that fill half of the hospital beds in the developing world. The topics include manual scavenging, sanitation for the urban poor, financing of sanitation, and the effects that climate change could have on sanitation, among many other subjects.
