Juan Valiente is an environmental activist from Zaragoza, Spain, whose climate engagement became central to his life after his son was born in 2015. He sees climate change as an urgent present-day reality and believes the strongest response comes from community-level action.

His work focuses on practical climate adaptation in his neighborhood, including a community garden with composting and organic farming, and projects to renaturalize municipal spaces by planting and watering vegetation in vacant urban lots during summer. He also promotes public engagement through video forums, guided botanical walks, and outreach activities. Overall, his approach combines community resilience, urban greening, and collective inspiration. Watch his short video below.
