Title | Description / Focus |
Putting Fishing Landing Sites and their Infrastructure on Spatial Aspect | This is his Master’s/dissertation thesis. It involves mapping and spatial analysis of fishing landing sites and related infrastructure in Bagamoyo and Kinondoni districts. lugoga.github.io |
Mapping and characterization of fish landing sites and related infrastructures along the coast of Kinondoni and Bagamoyo Districts, Tanzania | Very similar to above (or possibly the same work) focusing on spatial distribution, investment value, and infrastructure of fish landing sites. libraryrepository.udsm.ac.tz |
The decline in phytoplankton biomass and prawn catches in the Rufiji‑Mafia Channel, Tanzania | Analysis of trends (2002‑2014) in phytoplankton biomass and sea surface temperature, and linking them to prawn catches. Combines in‑situ and satellite/ocean‑colour data. dspace.nm-aist.ac.tz |
The Impact of Land Use and Land Cover Change on Water Quality in Lake Victoria Catchment: A Case Study of Nkangabile River at Nyegezi Bay, Tanzania | This involves using remote sensing / GIS to track how land use / land cover (LULC) changes affect water quality in that catchment. Mr. Masumbuko is one of the co‑authors. journals.udsm.ac.tz |
Graphic & layout contributions to “Report on Tuna Stock (Bigeye and Yellowfin) in the Exclusive Economic Zone of Tanzania** | He was involved in the design/layout/graphics of that technical report. That suggests involvement in fisheries data / assessment communication. |

Packages
A wior packaged built by Masumbuko Semba and Nyamisi Peter focusing on Easy Tidy and Process Oceanographic Data. The packages is basically developed to help marine and freshwater scientist access a large and varied format of in-situ and satellite data in easy way. In fact, the package has made data access in much easy way. The authors are trying to remove the barrier of data access and leave a space for scientists to focus in much deeper thinking of their field rather than spending several days to understand codes for a specific data download. The package contains several tools that allows scientist to get a wide array of datasets. And the funny things is that you get a tidy format result of the download, which is easy to handle in R and also to share it out of R environment. The tidy format is in form that many scientists familiar with Excel spreadsheet will find it handy. You can access this package through this link: https://github.com/lugoga/wior
