DENR's Metro Manila office has built mini-forests, linear parks and tree corridors since 2019, lifting the region's green cover from 12.08% (2015) to 20.48% (2021) and logging over 11,000 hectares of green space by 2025, with seedlings tracked at about 80% survival.

Context

Rapid urbanisation had stripped much of Metro Manila's tree cover, worsening urban heat and flood risk across the National Capital Region's 16 cities and one municipality. Since 2019 the Department of Environment and Natural Resources' NCR office (DENR-NCR) has adapted the national reforestation programme to the built-up city: mini-forests, linear parks, pocket gardens and tree corridors.

Results

Remote-sensing analysis shows NCR's green cover rose from 12.08% in 2015 to 20.48% in 2021 -- an increase of roughly 70%. By 2025, DENR-NCR had documented about 11,000 hectares of parks, tree-lined roads, gardens and other green assets, and reports an 80% survival rate for seedlings distributed through its Community Pan-Tree Program (100,000+ seedlings distributed).

Conclusions

Coverage remains uneven: of Metro Manila's 17 local government units, only Muntinlupa and Quezon City currently meet the WHO standard for green space per capita, and a 2024 academic tree-planting-prioritisation study (ISPRS) found planting has not yet been systematically targeted to the areas with the least canopy.

Conditions for success

  • formal memoranda of agreement with local governments to expand urban greening
  • adapting national reforestation programme to built-up, high-density city context

Common failure modes

  • only 2 of 17 local government units meet WHO green-space-per-capita standard; planting not yet systematically targeted to lowest-canopy areas (2024 ISPRS study)
