By the Foundation of Biospheric Activities, Argentina, conserving and restoring Andean forests and Chaco ecosystems in the Sierras Grandess of Córdoba. Acción Serrana began as a coalition of multiple groups and initiatives, together and in a staggered manner, the objectives imposed and achieved were:

In 2018: 10,000 Polylepis australis planted. In 2019: 50,000 Polylepis australis planted. In 2020: 100,000 Polylepis australis planted. In 2021: 100,000 Polylepis australis planted. In 2022: planting 150.000 Polylepis. Now we are producing 225.000 Polylepis tress to be planted together with Acción Andina.

This initiative has planted millions of trees over the Andes throughout South America and made visible the importance of these actions, for the protection of environmental services and the conservation of the biodiversity of montane forests, motivating the emergence of many new reforestation, regeneration and ecological restoration projects.

The projection for this Decade of Ecosystem Restoration, which is just beginning, is to increase the quantity and quality of trees to be planted in many areas of the Pampa de Achala Provincial Water Reserve - among the highest peaks of the Sierras Grandes de Córdoba. Our objective is to consolidate Acción Serrana as a regional movement, with the support of all the competent authorities and organizations with high impact at a global level, thanks to the reforestation financing and organization by ECOAN and Global Forest Generation in conjunction with the Foundation of Biospheric Activities & Treeangle Foundation, with the honor of being an national scale implementer of Andes Action, in each area where there is a firm partner of Acción Serrana in growth.

FAB works towards harmonizing human activities with the natural processes of the biosphere, via long-ranging ecological restoration projects, intercultural decolonization processes and avant-garde arts inspired in ancestral heritage. FAB works with ecological restoration and environmental education projects and activities projects based in South America, mainly Argentina and Brazil.

Consolidating environmental and educational actions in Brazil, Matutu Foundation has the mission of promoting social inclusion through participatory management, environmental education, improving the population's quality of life and sustainable use of natural resources. The Foundation consolidated environmental and educational actions creating a model experienced over decades of interaction integrated with the ecosystem and the different populations that inhabit it. Due to its community origin, Matutu Foundation has accumulated extensive experience in collective processes, developing consensual and participatory decision-making practices, identifying agents in the processes of mobilization and developing means of communication.

More than proposing ready-made models, the Matutu Foundation experiments with dynamic solutions and shares the results as the only way to cope with the accelerated transformation of the environment. Its main project is based upon the conservation the the Atlantic Rainforest through innovative bioregional forest fires management plans and training/certification/equipment for advanced forest fires brigades, together with an environmental education program and other related projects.

IREHOM studies, experiments and validates the new paradigms we must face in the 21st century, in a holistic, conscious, open, integral, synergistic and creative way. The main projects are related with the Bages Valley hydrological basin regeneration and prevention of forest fires, while developing new education infrastructures & practices, renewable energies innovations and food & medicines sovereignty.

Some Mediterranean stream basins are natural in the upper part and urbanised in the bottom. The basin makes a funnel so a big concentration of water in a small space creates big flooding problems. In Castellet some people have died for flood events. Due to the steep slope most of the water just flows down and the area is essentially dry. But when a natural space keeps water you can see the difference in the quality and health of the vegetation. There are also big issues of water capability in the farms/houses of the valley.

Castellet stream basin topography and its torrentiality has triggered numerous avenues and caused several damages in the last decades. In addition, this area is formed by immature forests, vulnerable in front of fire risk.

Defining and locating different actions for runoff water management in the basin, lets us increase the retention time to laminate the avenues and increase the humidity of the terrain. The project consists in the execution of lamination ponds, cribwall dikes, infiltration channel and fascines. Some works are going on successfully.

Most of the planning actions will be done using troncs and branches from the same forest. So we are going to manage the woods in order to have less tree density and bigger specimens.

The definition of actions in the basin, has allowed to calculate the volume of water that would intercept and compare it with the total volume of the runoff. The results show that for 2-year return periods the volume of water retained is around 38-66%, while for periods of 50-year it is down to 4-14%.
