1. The community is critical in solving its problems. We used Community Engagements to design an appropriate and sustainable waste management system. The tenants were willing to work with the landlords to collect money and hire private waste management collectors to collect their garbage. However, the community needs to be supported in the waste management behaviour to sort waste appropriately and take it to respective waste management centers like recycling plants for plastics and biodegradable to landfills. We are still working on this experiment for more lessons. 2. Following the Kampala Drainage Master Plan by Kampala Capital City Authority (KCCA) using the Crowd Mapping to generate a baseline map with key drainage systems, was critical. We carried out this experiement  and covered the following;- i) Survey, map and design a total of 8 tributaries in Kiggundu and Sebina Zones, connecting them with the existing main drainage channel. Designs must comply with the technical, legal, and social requirements, aligning with the Kampala Capital City Authority (KCCA) drainage master plan and stormwater management.  ii) Drafted and final designs are subject to discussion and approval by the community, UNDP, Kampala Capital City Authority (KCCA), and National Environment Management Authority (NEMA). iii) Collaborate with the community to construct the designed tributaries, employing cost-effective, environmentally friendly, and durable solutions. iv) Construction activities will include the following;- - Installation of appropriate culverts to allow a smooth flow of water. The tributaries should also connect to the main drainage systems. - Desilt the main drainage channel to allow for a smooth flow of water collected from the drainage tributaries to the Lubigi channel. - Establish a green belt comprising trees, flowers and grass alongside the drainage channels. - Conduct community sensitization sessions on the importance and ways of maintaining an effective drainage system. 

Our work is still in progress registering more lessons and as we conclude the experiments we will have a  clear handover process. For now, we are working with our Nature, Climate, Energy and Resilient Team (NCER) for technical guidance and to ensure sustainability during handover.

We used hydrological analysis, based on a 12.5m x 12.5m grid digital elevation model sourced from: https://www.eorc.jaxa.jp/ALOS/en/aw3d30/index.html) was undertaken to delineate the project site based on the existing Katanga channel and the identified outlet culvert at the Kampala Northern Bypass (KNBP), where the Katanga channel feeds the Lubigi channel. This analysis produced the general extent of the Katanga subbasin, extending to the top of the hills of Makerere, Mulago and Nakasero. The hills majorly contribute to the Katanga sub-basin run-off. The analysis revealed that run-off is directed to the lowest-lying centre of the sub-basin and continues in a northward direction towards the Lubigi channel. The hydrological analysis also identified the natural flow paths, termed tertiary channels, and these extended away from the secondary Katanga channel in an East-west direction.

Yes, it was necessary to apply all the above methods as they are critical in not only documenting the lessons but also to cause behavioural mindset change. We co-created the drainage channels with the community as they own the land through which the channels were to pass, with the KCCA as they are mandated in the execution of the Kampala Capital city drainage master plan and with the National Environment Management Authority as they are keen devising appropriate solutions that are not detrimental to the environment.
