Multidisciplinary outdoor education for women recovering from trauma and youth with disabilitiesMultidisciplinarna outdoor edukacija za žene koje se oporavljaju od traume i mlade s invaliditetom

• Co-developed a holistic toolkit combining animal therapy, psychology, sociology and sustainable-living practice, drawing on a network of EU-based practitioners.
• Bulgaria (2023): designed and ran equine-therapy sessions for participants healing from past trauma; adapted methods alongside therapists and community organisers in residence.
• Italy / Umbria (2024): hosted by Quest, an Italian non-profit that reconnects schoolchildren with nature through outdoor activity; co-led rock climbing, hiking and other physical practice.
• Bridged the programme into local Umbrian villages, sharing meals and craft with elders (a long afternoon cooking with Nona Laura among them) and strengthening the link between outdoor education and rooted community.

• Sudjelovao u razvoju cjelovitog priručnika koji spaja terapiju životinjama, psihologiju, sociologiju i praksu održivog života, oslanjajući se na mrežu stručnjaka iz EU-a.
• Bugarska (2023.): osmislio i vodio terapijske sesije s konjima za sudionice koje se liječe od prošlih trauma; prilagođavao metode uz terapeute i organizatore zajednice.
• Italija / Umbrija (2024.): kao gost neprofitne organizacije Quest, koja djecu kroz boravak na otvorenom ponovno povezuje s prirodom; suvodio penjanje, planinarenje i druge fizičke aktivnosti.
• Povezao program s lokalnim umbrijskim selima, dijeleći objede i vještine sa starijima (među njima i dugo poslijepodne kuhanja s Nonom Laurom), jačajući vezu između outdoor edukacije i ukorijenjene zajednice.
