Why technology often fails to replicate the “natural services” of ecosystems

By KESLS RAM -
When we chlorinate water, or use other similar biocides, we create an environment toxic to many microbes (including many fecal-oral parasites). This has saved many millions of lives. However, this same intervention has also favored the persistence of another kind of parasite, nontuberculous mycobacteria. Nontuberculous mycobacteria turn out to be relatively resistant to chlorine. As a result, chlorination  creates  conditions  in  which nontuberculous mycobacteria thrive.

The Spillover Effects of Water Supply Infrastructure Development: A Theoretical Model | Asian Development Bank

By KESLS RAM -
One of the main challenges in low-income Asia and the Pacific countries is users' willingness to pay for water services. In contrast, investors and private operators in the water sector prefer a high rate of return. This has often led to the failure of public-private partnerships for water projects. However, if we look at the overall picture of the development effects of water supply infrastructure, including spillover effects or externalities, the impacts are significant.  https://www.adb.org/publications/the-spillover-effects-of-water-supply-infrastructure-development-a-theoretical-model Best Regards Seetha Ram

Asian Water

By KESLS RAM -
Institutions matter for service delivery Public water sector institutions in many developing countries have inherited archaic policies that are ineffective. A change in mindset is imperative to revive decaying water utilities.   By K.E. Seetharam   At the Fourth World Water Forum in Mexico in March 2006, the Asian Development Bank was one of the few institutions to raise the flag on the need for good governance in the water sector. Although policy aspects are important for development, ADB's concept of good governance focuses on the effective management of water infrastructure to ensure proper delivery of services.   In essence, good governance is about changing attitudes and behaviour to ensure that water sector institutions actually deliver to their citizens what they say they will deliver. Institutions have two dimensions—the policies, and the persons who are responsible for implementing them. A basic issue that arises in relation to good governance is how well the governm...

Drinking Water is Food

Drinking Water is Like Food— bottle it and deliver it to the poor immediately   K E Seetharam   The Asia Water Watch 2015 , commissioned by ADB, WHO, UNDP, and UNESCAP, estimates that another 700 million people—at minimum—will need to be served in Asia over the next decade to meet Millennium Development Goal (MDG) target 10 on safe drinking water alone. When I started to coordinate the preparation of report in 2005, the big question that I had in my mind was how can this massive target be achieved expeditiously? Developing country governments and development organizations are attempting to partly answer this question. In early 2006, I assisted ADB in announcing its Water Financing Program 2006-2010. The Program, one of the most concrete actions publicly announced so far by international organizations, will double ADB's investments in the water sector to over $2 billion annually for the next five years. But typical development projects take at least 3 to 5 five years for their ...
