Greening is a term that we are very familiar with so far. Reforestation is synonymous with planting trees. Reforestation is nothing but an effort to rehabilitate critical land and other land outside the forest area with the aim of restoring, maintaining, and improving land functions according to capacity, namely for the benefit of water management functions, production functions, and protection functions.
The purpose of reforestation is to control flooding and soil erosion, improve people’s welfare and change the behavior of farmers as conservationists of natural resources.
Critical lands that are usually prone to erosion with low soil fertility and limited water problems make reforestation activities and restoration of soil fertility absolutely necessary.
One of the main factors causing soil damage is the surface runoff that occurs when it rains. This rain flow erodes and washes away the top layer of soil which is relatively fertile so that the level of soil fertility in the area is getting lower and lower.
The role of reforestation on humans and the environment, among others:
- Climatological Functions: As a microclimate regulator,
- Protective Function: For protection,
- Hygienic Function: Play a role in environmental health,
- Hydrological Function: As a regulator of water supply in the soil,
- Erological Function: Function in preventing erosion,
- Edapis function: As a place to live for animals,
- Aesthetic Functions: Having the value of beauty,
- Psychic Functions: Psychiatric,
- Educational Function: Education,
- Ecological Function: Enhancing the quality of environmental living space, and
- Socio-Economic Function.
