Improve vegetation biomass Reduce, prevent, and restore degraded land Improve or protect the soil Protect or restore ecosystems To maintain / enhance biodiversity √ Reduce the risk of disasters (e. g. drought, droughts, floods, sandstorms, etc.) √ Adaptation to climate change and its effects (e. g., enhanced resilience to drought and warming) Mitigating climate change and its impacts (e. g. increased carbon sink capacity) Generating economic benefits (e. g. increased income) Generating social benefits (e. g. reducing the consumption of natural resources and reducing poverty) Other uses (detailed description): ………………………………………………………………… 表

Technical link Key technical points Implementation season / month 1. Planning / designing of shelterbelt Insert 1: Planting scheme: shelterbelts compromise 2-5 tree lines forming the windbreak about 5-15 m wide and 15-25 m high.
Insert 2: Rectangle grid layout of shelterbelts. Spacing of the rows is denser against the prevailing wind.2. Selection and collection of trees seedlings 3. Clearing and preparing land for planting of shelterbelts late autumn and spring 4. Pits for planting the seedlings are dug 5. Tree seedlings are planted late spring 6. After planting each seedling is watered for up to two years Schedule or attachment (with relevant technical parameters, add schedule or attachment information here) 表
