Navigating urban sprawl and green space loss: strategic approaches for sustainable development in Nairobi

Abstract

Urban sprawl poses a significant threat to green spaces in rapidly expanding cities like Nairobi, Kenya, undermining both environmental sustainability and social equity. This paper explores the dynamics of green space degradation, using Kahawa West Community Park as a case study to inform targeted interventions. The study aimed to identify the key factors driving park degradation, assess community usage and perceptions, evaluate the effectiveness of current management strategies, and propose sustainable development strategies. Using a mixed-methods approach, data was gathered through surveys (n= 338), interviews with key informants, and field observations. The results revealed severe park decline: 68% of respondents rated cleanliness as poor or very poor, citing waste accumulation and lack of sanitation, while 62% reported significant biodiversity loss due to habitat fragmentation. Infrastructure was also in poor condition, with 70% of respondents identifying inadequate facilities. Despite these challenges, only 25% of residents visited the park regularly, with safety concerns and a lack of recreational amenities cited as major barriers. The study highlights the failure of management, as evidenced by low ratings of coordination and responsiveness, and identifies funding shortages (75%) and encroachment (80%) as significant challenges. Findings emphasize the need for policies that protect urban green spaces, with recommendations focused on collaborative governance, sustainable financing, and targeted interventions to address the consequences of sprawl. This research contributes to the ongoing discourse on sustainable urbanism, offering practical insights for policymakers in Nairobi and other rapidly growing cities.
