I recently came across the article ‘Vanishing Wisdom‘ in the Tehelka blog, which made me want to learn more. It was about a traditional water management system in the Uttarakhand region in northern India that has worked for years, but is being destroyed by funding meant to ‘modernize’ it.
The chaal is a tank structure built of simple earthen walls that that was traditionally constructed around springs in the hills, meant to capture water for livestock or human consumption, but which also turned out to promote the recharge of groundwater. People noticed that after building a chaal, downhill springs had more water for longer in the year, so more were constructed.
In the Tehelka article, Amitangshu Acharya explains, “Chaals became a critical component of healthy watersheds. 35 years ago, chaal construction and management went through a sharp decline due to migration by rural youth to towns out of distress. The wisdom in maintaining chaals was left to village elders. As a result, decision-makers in today’s villages often think chaals are mere storage bodies. Government rural development programmes, hence, attempt to “modernise” chaals based on this misconception.”
They began to finance ‘improvements’, which meant replacing earth and stone with cement, which prevented the water from infiltrating, leading in turn to lowering groundwater levels and drying up of springs. Interestingly, part of the problem was that it costs almost nothing to build or repair an earthen chaal, and the agencies had budgets they needed to spend.
The author says, “Making a chaal involves no purchased material and just a day’s worth of labour for a group of people. Hence, NREGS funds allocated to a gram panchayat (local government) would largely go unspent if chaals continued to be repaired or constructed using local mud and rocks. Gram Pradhans and Block Development Officers decided to increase costs, thereby utilising funds –and increasing the kickbacks they would receive.”
This is speaking about a government program, but non-profit development schemes can be vulnerable to the same need to spend their budgets.
The chaal story is a good reminder to look past the ‘activities’ and ‘accomplishments’ sections of development project reports. It may look great to say ‘constructed 5 new water storage tanks’, but the progress reported may in fact be a step backward.

The Director of Columbia Water Center’s India office, Kapil Kumar Narula, mentions chaals as one of many traditional water management practices in his paper ‘Vulnerability and adaptation to climate variability and water stress in Uttarakhand State, India‘.
