Statistics published by the United Nations in 2023 show that approximately 55% of the world’s population currently lives in urban areas. People are increasingly moving to cities for various reasons, most notably for employment opportunities and the pursuit of better living conditions. However, a number of studies indicate that urbanisation can also have a negative impact on mental health. Research by White, Weaver, Hutton and McGraw (2017) highlights that living in urban environments affects brain functioning in ways that may be harmful. Further research shows that young people are particularly vulnerable to mental health difficulties related to urbanisation and disconnection from nature (Nelson & Nwimo, 2012). According to data published by the World Health Organization (2022): – mental health conditions account for 16% of the total global burden of disease and injury among young people aged 13 to 19; – approximately half of all mental health problems begin before the age of 14, yet many remain unrecognised and untreated. One reason for this is that adolescence is a developmental period marked by identity exploration and transitions, during which symptoms are often overlooked; – anxiety is one of the leading causes of illness and reduced functioning among adolescents worldwide and has been steadily increasing since 2015 (Bell & Blanchflower, 2021). As youth workers, we have observed a significant increase in mental health difficulties among the young people we work with. This trend has been present for several years and intensified during the COVID-19 pandemic. In the post-pandemic period, additional stressors have emerged, such as the wars in Ukraine and Palestine, general uncertainty about global peace, and growing economic pressures caused by inflation. One of the most effective approaches identified through our review of professional literature, conducted in order to better understand how to support young people facing emotional and mental health challenges, is wilderness therapy. Research indicates that nature-based therapeutic approaches can make a meaningful contribution to mental well-being by fostering connection with nature, encouraging self-reflection, and strengthening emotional regulation skills. The overall aim of the project is to empower youth workers with the knowledge, skills and confidence to use nature-based and outdoor-informed approaches to support young people experiencing mental health challenges in a safe, ethical and youth-centred manner. The objectives of the training are as follows: Objective 1: To deepen participants’ understanding of the mental health challenges faced by young people in urban environments and of effective ways to support young people in such situations. Objective 2: To develop knowledge of wilderness therapy, including its effects and benefits for mental health. Objective 3: To explore practical ways of applying wilderness therapy in everyday youth work contexts. Objective 4: To introduce outdoor tools and activities and examine their impact on young people’s mental well-being. After completing the training, participating youth workers will have enhanced knowledge, concrete tools and practical experience in the field of youth mental health and will be equipped to use wilderness therapy and outdoor approaches effectively when supporting young people experiencing mental health challenges.
