OSC Neighborhood Solid Waste Study 2019

leave a comment »

Preparing to run a solid waste survey at a modern house east of the OSC campus.

The 2nd semester is a time of class field trips to various recycling and solid waste operations in the OSC neighborhood.  The DP Geography class is preparing to conduct field research in Sinharaja so as a trial they conducted a field survey of solid waste patterns in the OSC neighborhood. There were several stages to this operation:

  1. Taking a preliminary observation-based walk to assess the study area.
  2. Devising the research questions
  3. Creating an appropriate survey using Survey 123
  4. Preparing a base map using OpenStreeMap as well as new 1:10,000 data from the Sri Lanka Survey Department. Revieiwng and updating data on OSM for the OSC neighborhood
  5. Conducting the field work (over two lessons)
  6. Compiling, processing and graphing the data.
  7. Sharing the data in a poster, individual assignments and online (this post)

As a part of the project the class worked with a variety of maps to get a sense of their study area.  OpenStreetMap is a great source but most of the building have not yet been mapped. Previous classes of OSC students have mapped the school campus but the Class of 2020 worked to expand the area. The maps below show the progress that they made on this ongoing project.

 

CONCLUSION

The field study was completed after two blocks of data collection in the OSC neighborhood. Together the class was able to survey 26 different households near to the OSC campus. We have a much better sense of of our neighborhood though it would be good to continue the study and get more houses surveyed. There were a few conclusions.

  • Most residents are getting some sort of municipal solid waste pick up. 23 of 26 respondents(86.5%). Respondents mostly appeared satisfied with this arrangement abut several remembered times when the collection system had broken down in the past 2-3 years.
  • 23 of the 27 (92.3%) respondents are separating waste. This makes sense as it is now required by the municipality.
  • A few residents stated that they did weekly burns of leaves and paper. (3 of 26 or 11.5% households surveyed). However it seems, based on observation, that other items (Tetrapacks, plastic bits) are being mixed in with these burn piles.
  • Only a few households were composting (3 of 26 or 11.5% households surveyed).
