Social Responsibility: Shokay & UPW have committed our joint Community Development Fund towards regenerating 240 mu of grassland (equivalent to 30 football fields) in Sichuan. We will start seed planting Spring of 2022, and invite you to join! Shokay and UPW will be partnering with Trachung Tsang Cultural and Environmental Protection Center, led by Tibetan environmentalist Drakyom Palzang. Palzang has developed a unique methodology that empowers local Tibetans and their yak herds to work together to combat desertification. Under his guidance, local Tibetans first till the land and plant the seeds. They then lead their yak herd onto the land to burrow the seeds into the soil and fertilize it with their dung. Over the last 15 years, Palzang has fine-tuned this method and led over 1000 Tibetans to recover 13,000 mu of grassland.
