In this project we attempt to investigate the level of changes in biodiversity in space and time at the Yongwa quarry site, principally using GIS tools and methodologies. Identifying these dynamics can assist in predicting habitats at the site that are or will become most vulnerable to changes in the future. Locally abundant vegetation species as well as locally depleted vegetation species in and around the quarry site will be identified at the end of the project. The goal of the project is to generate and develop biodiversity data of the area, which will be a critical decision making tool during the closure and rehabilitation stage of the quarry site.

Quarry communities in retrospect

Considering the spatio-temporal modification in the biodiversity around Yongwa, we deem it necessary to look at the communities and activities that surround the quarry and their influence on biodiversity in the area. This was carried out through interviews and interactions with the chiefs, elders and community members within the quarry area.

The past is key to the future!

We continue to probe the underlying factors that have contributed to shaping the current ecological state of the Yongwa area. Mr. Moses, a native of the area, provided us with his unique historical perspective on the subject matter. He explained to us how past events have shaped the biological diversity of the area. Watch the video for excerpts of our discussion with him.
