Description of locals satisfaction with the project
"Despite the existence of Nairobi City’s Physical plans, which are designed to protect the river, the central obstacle lies in their efficient execution and enforcement. Inadequate implementation has resulted in uncontrolled urban expansion, the proliferation of informal settlements, increased industrial activities, and encroachment of agriculture near the riverbanks" (Ref 1);
'"The work was begun more or less two months ago”, says one of the workers from the Ministry of Environment, involved in waste collection. “We’re not volunteers, we are workers paid by the Government, but we do not have a contract. They can send us away whenever they want.”'(Ref 12).

Trade-offs & Negative impacts
Please specify Trade-offs & Negative impacts Selected
-Habitat destruction, fragmentation, or alteration (e.g. use of monocultures): "However, populations along the rivers removed a considerable number of trees with little replacement, compromising the biological health of the river environment. Nyawira Karangi (2017) while assessing the magnitude in acreage of built-up areas encroached over the 30-metre riparian buffer zone between 1988 and 2014 noted that Nairobi River had the highest acreage of built-up areas within the riparian reserve, with a sharp spike experienced between 2010 and 2014 (Figure 1)" (Ref 1).

Reaching original project goals
Please specify the achievements of the project goals
Biodiversity Goals:
- Improved waste management: "Removal of 6000 tons of solid waste at the Demo stretch" (Ref 4);
- Enhanced protection and restoration of freshwater ecosystems/Achieved improved soil quality/-Achieved improved stability of slopes: "Controlling soil erosion and filtering pollutants from entering the river were accomplished through replanting of indigenous trees and flora along the riverbanks" (Ref 1);
Increased number of species present: "4000 tree seedlings planted in the upper catchments" (Ref 4).
Social justice and community:
- Increased support for education and scientific research: "Phase I constituted a situation assessment of water quality, public awareness, community outreach through pilot income generation projects and capacity building. Phase II of the programme (June 2001 - December 2003) was a pilot initiative, focusing on a tributary of the airobi River system - the Motoine/Ngong River" (Ref 5);
-Increased awareness of NBS and their benefits: "Six public awareness forums on the importance of the program held" (Ref 4);
-Decreased crime rates: "Process of on-going stoppage of 367 illegal discharges that were identified" (ibid.).
