Cities and Mountains

Breakout session

Date: 19 November 2014
Time: 17:15 - 18:45 hrs
Venue: Committee Room A, BMICH, Colombo
Sponsor: ICIMOD


Cities that are surrounded by or next to high mountains face additional challenges in managing air quality. Topography influences ventilation by blocking or channeling air flow. It creates night-time drainage flows that pool cold air in low areas, enhancing temperature inversions. The diurnal patterns of air pollution are affected not only by the diurnal patterns of emissions, but also by the local meteorology that is strongly influenced by the mountains.  

Meanwhile, mountain environments are often affected by emissions from far-away urban and industrial centres. Pollutants transported over long distances affect not only air quality and visibility in mountain areas, but temperature, precipitation patterns, and even snow and ice cover. However, the effects are not one-way. Melting of glaciers and rainfall in mountain areas affect water availability and floods in far-away downstream cities as well.

Objectives

  • To raise awareness about topographic effects on urban air quality
  • To increase understanding about linkages between urban areas and far-away mountain environments
  • To share experience about designing relevant science-based policies

Intended Outcome

  • Statement in BAQ plenary outcome document

Target Participants

Policy makers from countries with mountains.
