Medi XXI GSA · Forestry & environmental engineering
Since 2001 we have designed engineering solutions to manage land, prevent wildfires and move towards truly sustainable development.
Who we are
Medi XXI GSA was founded in 2001 in Carcaixent (Valencia, Spain) with a clear goal: to work for a more sustainable world. We are a multidisciplinary team of forestry engineers, environmental scientists, agronomists, biologists, emergency managers and land-use planners.
We work for public authorities, companies, organisations and individuals. We design projects and we also carry them out: we have our own agroforestry crew, an AESA-certified drone unit and our own patents, such as the SIDEINFO wildfire defence system.
About usOur values
No longer an option, but a necessity.
We approach every project in a cross-cutting, integrated way: only by combining economic, social and environmental goals can we achieve real sustainability without compromising future generations.
Comprehensive, sustainable, functional solutions.
Every project is unique. We respond with honesty, rigour and responsibility: we will not tell you what you want to hear, but what you need to know — and we will give our all to get it right.
Engineering comes from ingenuity.
We hold our own patents and intellectual property registrations resulting from our research, and we build digital tools — always with realistic solutions adapted to the resources available.
Ubuntu: I am because we are.
We believe in cooperation, empathy and the common good. We work with communities, villages and teams, because together we are stronger. We care for rural areas and we work from them.
