Water and human rights

Industry Research Grant: "Realizing Human Rights for Water in Industry"
How to reconcile the broad and universal nature of the human right to water with the local realities of water security and water governance? 

Our new framework addresses this question to facilitate a preemptive implementation of the human rights to water in the context of water-intensive industrial operations, such as mining, commercial agriculture, hydropower beverages and textiles. 
  • Check out the video of our session at World Water Week 2022, and access the white paper describing the framework here
  • ​We recently presented this work at the Social Forum of United Nations High Commission for Human Rights in Geneva (Switzerland). Read more about it here.
  • We are hosting a side event at the UN Water conference at the United Nations HQ in New York City on Thursday March 23 2023 at 3:30-4:45 pm ET, where we will present the framework in discussion with a roundtable panel of experts from the industry, academia and civil society.

Socio-Hydrology of Climate Change

National Science Foundation Grant EAR 2142967: "CAREER: CAS-Climate: Sociohydrology to link climate change and its societal impacts"
[Press]

Our Approach

Questions that we Ask

  • How are socio-environmental systems changing in data-scarce regions?
  • What are the key drivers of these changes? To what extent can they be attributed to exogenous (e.g. global climate) or endogenous (poor policy) sources?
  • Will there be more more conflicts in a changed climate where water resources will be more variable? What role (if any) will physical landscape processes play in that relationship?
  • What does it take for cooperation to emerge over internationally shared water resources? What role does trust and information access play in that process?
  • When does human (trade, migration, information) and hydrologic (rivers) connectivity enhance societal resilience to climate shocks?
  • How can new information paradigms (e.g., remote sensing, modeling and social sensing) and modern data analytics be used to address critical information gaps for improved water, health and energy policy?​

Methods that we develop

We combine data science, hydrologic modeling and economics to monitor, evaluate and predict rapidly changing coupled human water systems in data-scarce regions. An overview of our approaches and focus areas can be found in a recently published review paper in Water Resources Research [click here for access].

A non exhaustive sample of the methods that we developed is listed below -- please click on the keywords for example publications. A full list of publications is provided in the "Publications" tab of this website.
