Basin Assessment Scenario Intervention Tool (BASIT)

Overview

The Basin Assessment Scenario Intervention Tool (BASIT) demonstration project will develop a geospatial decision support tool that enables corporates to understand the current and projected health of an entire watershed. It will also establish the hydrological modeling foundation for developing science and context-based goals, while identifying and prioritizing potential intervention options aimed at improving watershed health for all stakeholders. The demonstration project is within the Indus River basin, with a particular focus on the River Ravi sub-basin. Ravi River is one of the five eastern tributaries of the Indus River in Pakistan. A major source of water for irrigation in the region, Ravi River is under intense pressure from industrial and municipal wastewaters from major cities including Lahore, Sheikhupura, and Faisalabad. Studies have shown that approximately 50% of all river pollution in Pakistan originates from Ravi.

Objectives:

  • Tool: Create a decision support tool which provides basin level insights that can be used by Levi Strauss & Co and other stakeholders to set science and context based water targets
  • View: Provide local stakeholders, including Levi Strauss & Co vendors and other water users, with a shared view of the overall watershed level health
  • Platform for solutions: Provide a common hydrological foundation for identifying potential opportunities to address water issues via local solutions (as part of V2 functionality)
  • Collaboration: Broaden and deepen local stakeholder engagement to reach solutions

Functionality:

The tool will deliver three-fold primary capabilities: current watershed health, forecasted / scenario, and company impact. The goal is to identify new behavior required to reach long-term watershed sustainability.
  • Current watershed health: Assess current and recent historical watershed level health to quantify existing imbalances between supply and demand. Assess key metrics of the watershed, including water quantity and quality on a geospatial basis.
  • Forecasted / scenario: Identify watershed balance scenarios for future time horizons of interest to corporate end-users and local stakeholders. Describe scenarios to understand range of possible changes in water availability on a multi-year time horizon by specific location (spatial temporal analysis).
  • Company impact: Incorporate existing Levi Strauss & Co footprint—defined as current and projected water use in specific localities within the watershed. Tool output creates watershed specific recommendation on water use changes versus baseline water use for Levi Strauss & Co to discuss with their supply chain for setting context/science based water targets.
