Kirstenbosch infrastructure concerns resurface as SANBI gardens face R839m backlog

Infrastructure concerns have reappeared for the Kirstenbosch National Botanical Garden as the South African National Biodiversity Institute (SANBI) faces an estimated R839 million backlog of necessary upgrades and maintenance by 2029/30. This revelation comes shortly after SANBI dismissed claims that the garden was deteriorating, maintaining that it remains a premier botanical and conservation destination.

The Portfolio Committee on Forestry, Fisheries and the Environment was recently briefed on the infrastructure issues at Kirstenbosch and the broader network of SANBI gardens.

The gardens are grappling with aging facilities, historical underinvestment, and increasing demands, which are straining essential infrastructure such as water systems, electricity, roads, security, and visitor amenities. These facilities, many of which are over a century old, require restoration and modernization to meet contemporary safety, accessibility, and sustainability standards.

Despite receiving R180 million in 2024/25, SANBI's projected infrastructure needs for 2027/28 are R741 million, with the backlog set to rise to R839 million by the same year if adequate investment is not secured.

The financial strain affects various aspects of the gardens, including staffing, with critical vacancies particularly in horticultural and technical roles. While volunteer assistance and public-private partnerships offer some relief, they are not sufficient replacements for long-term investment and institutional capacity. SANBI faces the challenge of prioritizing projects, including income-generating facilities, conservation infrastructure, and compliance with health, safety, and legal requirements.

Despite these challenges, SANBI has achieved some infrastructure successes, such as the Boomslang walkway and upgrades to research and visitor facilities. Plans are underway for further solar installations, irrigation improvements, and enhanced security measures. Kirstenbosch, one of Cape Town's top tourist attractions and a crucial center for biodiversity conservation, research, and education, welcomed approximately 780,000 visitors in the last financial year.

However, the committee emphasized the urgent need for increased financial and operational resources to ensure the long-term sustainability of the gardens, lest deteriorating infrastructure undermines their status as world-class centers for biodiversity, tourism, and community engagement.
