Kenya Sustainable Cities - Defining Airshed Management Zones

July 31, 2018

Most are familiar with the term watershed. Basically the landmark features that form the boundaries of where water flowing in the same direction converges. In geographical terms, a drainage basin.

We can monitor water basins and their corresponding watersheds.

Watershed examples in Kenya include 

 

Tana River

Thiririka River

Counties can identify and manage watersheds within their boundaries and can cooperate across boundaries as well

Similarly, an airshed demarcates the boundaries within which land-based emissions and particulate matter flow towards the air. For example, within a given county, where are high concentrations of industrial activity, garbage burning, cookstove use, traffic congestion...

Our goal with airshed management is to monitor the aggregate effects of human activity on air quality and the resulting impacts on biodiversity, human health and, yes, water quality. 

 

We are concerned with noxious emissions and Green House Gases as well as Particulate Matter levels (both naturally occurring and from human pollution)

Effective airshed management is critical for both improved human health and for compliance with international agreements such as COP21. 

 

New Zealand has a publicly available guide on population sizes and particulate matter levels that should be monitored in airshed management

Kenya has laid the foundations for a national airshed management system

CSTI Managing Trustee, Prof Shem Wandiga (FRSC, EBS) has been conducting research on air quality at selected sites across Kenya. The data are the beginnings of the type of data collection needed for effective airshed management.

 CSTI - What inspires us:

 

We are a multidisciplinary team of researchers and practitioners who believe that the scientific and technological knowledge we develop is a legacy trust we create for the community.

Some people are artists, others give inspirational speeches.  We deliver understanding that can be adapted to solve ecological and industrial problems.  The eagerness with which this understanding is received and used is what inspires us to do our work.

We  must treat the earth well. It was not given to us by our parents, it is loaned to us by our children.

Mtunze ardhi vyema. Hamkupewa na wazazi, bali mlikopeshwa na wazawa wenu. (Swahili)

 csti milestones: 

 

Sept 16, 1998:   Micro-Science kits were developed for schools and are still in use.

 

1997 to 1999:  Micro-Science kits were developed for schools and are still in use.

 

2010:  Conclusion of our Sakai Community Resilience to Drought project in which over US $300,000 total funding was leveraged to develop a replicable model for community resilience to drought.  The model was adopted by Kenya government. (See IISD website for additional details)
