rainwater harvesting
Rainwater harvesting is the collection of rainwater that falls on site (usually on rooftops). It is primarily used for irrigation, washing, or other uses, although it can also be used for drinking water if properly treated. Rainwater harvesting is a valuable way to reduce or even eliminate the use of municipal drinking water without requiring individuals to reduce their water consumption. This approach is, of course, more effective in rainy climates than in dry areas.

oak trees
The oak tree is one of the oldest and most valuable plant species in Iran, growing widely in the Zagros forests and playing a fundamental role in the natural sustainability of this region. With a very long lifespan that sometimes exceeds 2,000 years, it is among the species resistant to drought and severe temperature fluctuations, and it is able to adapt to harsh climatic conditions. Oaks usually grow in groups and are found abundantly at various altitudes, especially on the southern slopes and foothills of the Zagros. In addition to its environmental importance, the oak tree has great economic and cultural value. Its fruit and leaves have been used, in the past and present, in nutrition, medicine, dyeing, and the leather industry, and the livelihoods of many local communities have depended on this tree. Oak forests play a vital role in the balance of the ecosystem by preserving soil, preventing erosion, regulating water resources, and creating habitats for various animal species. However, in recent years the oak forests of the Zagros have faced serious threats such as successive droughts, fires, excessive tree cutting, and improper exploitation—factors that have reduced the forest area and weakened this valuable natural asset. Protecting, restoring, and developing oak trees is essential not only for preserving the environment but also for the sustainability of the lives of current and future generations in the Zagros region.
