BUMP website transitions

Hello everyone!

In 2024, I  celebrate 10 years that the BUMP website has been operational!

With my departure from the Stockholm Environment Institute (SEI) – from Jan 1 2024 –  this site will now be maintained by myself and supported by my environmental firm, “Leafbird Consulting LLC”.

I aim to keep this site running. If you would like to help, there are at least 2 ways:

  1. You can help fund the costs involved in keeping the website going.
  2. I would love to collaborate with you on the urban metabolism of Bengaluru and other Indian cities. Please contact me to co-produce additional knowledge on urban sustainability that we can share on BUMP into the future.

I thank everyone who has been part of this journey, and invite you to keep going with me!

With warm wishes for a safe and happy 2024,

Bangalore Urban Metabolism Project Episode 1: Introduction

This episode introduces the Bangalore Urban Metabolism Project (BUMP), an initiative of the Stockholm Environment Institute with the Indian Institute of Management – Bangalore (IIM-B) and the Indian Institute of Science. Dr. Deepak Malghan talks about the different challenges that Bangalore (Bengaluru) faces surrounding water, including water supply, demand, and hydrology. The key questions motivating the project are described.

Bangalore Urban Metabolism Project Episode 2: Objectives

In this episode, the origins of the Bangalore Urban Metabolism Project (BUMP) are explained by SEI’s Dr. Vishal Mehta. Dr. Deepak Malghan, from the Indian Institute of Management – Bangalore (IIM-B), explains the interactions between efficiency, sustainability and equity. The Indian Institute of Science’s Dr. Sekhar Muddu explains the major questions concerning the city’s groundwater that are addressed in this project.

Bangalore Urban Metabolism Project Episode 3: Monitoring

In this episode, Dr. Sekhar Muddu (Indian Institute of Science) – along with his researchers Sanjeeva Murthy and P. Giriraj – go into the details of the groundwater monitoring that was conducted in Bangalore from December 2015 through 2017. At 150 locations, every month, the groundwater levels were manually measured. The data collected will be analyzed to understand the groundwater budget for the city.

Bangalore Urban Metabolism Project Episode 4: Challenges and Learnings

SEI’s Dr. Vishal Mehta starts this episode with some of the main challenges of the Bangalore Urban Metabolism Project (BUMP). Dr. Mehta and Dr. Deepak Malghan, from the Indian Institute of Management – Bangalore (IIM-B), discuss some of the learnings and how these could be linked up with the policy-making apparatus. Examples from other places are presented.

Groundwater measurements ongoing: Video

Since December 2015, the Bangalore Urban Metabolism Project has been measuring groundwater depths in 150 locations in Bangalore, every month. This video shows one such measurement, near Avenue Road, made by Giriraj and Sanjeeva, from the Indian Institute of Science.

Although each measurement takes only a few minutes, traveling through Bangalore traffic takes hours. On October 24th, 2016, I joined P Giriraj and Sanjeeva Murthy for a day in which we measured groundwater depth at 15 locations in different parts of Bangalore. Just 15 measurements on a day took 8 hours, thanks to traffic!

Bengaluru’s water insecurity is manifested in the diversity of its household water supply portfolio

Households manage their present and future financial needs using portfolios, with diversification being a key tool used to balance risks and returns. Indian households manage their water in a very analogous way to how they manage their financial and other assets. Households cope with the essential water insecurity imposed by inadequate public water supply, by investing in a diversity of water supply and demand management options. Understanding this complex household level water supply and demand balance in Indian cityscapes is essential for at least four compelling reasons: Continue reading
