=================================== Results =================================== **Figure 12** show that adaptation actions in the Ecosystems sector yield significant benefits, with a net gain of US$388.6 million from 2025 to 2050. The primary benefit, valued at US$402.8 million, comes from improved air quality regulation through reforestation of 14,500 hectares, using a conservative estimate of US$4,686 per hectare. While reforestation incurs the highest cost at US$14.9 million, it provides long-term ecological and economic value. Other costs include forest planning, training, and monitoring, while additional benefits include erosion control, temperature regulation, and tourism enhancement. .. figure:: ../../_static/_images/12_ecosystems.png :alt: Models used on the cost and benefits analysis :width: 80% :align: center **Figure 12:** Costs and benefits disaggregated from the modelling process for adaptation actions in the Terrestrial Ecosystems sector.
