The Water Quality Monitoring Programme is an integral part of Guapiaçu III Environmental Education scheme at Regua. This initiative aims at raising young people’s awareness of water resources, its use and its care indicating the association between forest and water provision.
The programme targets Cachoeiras de Macacu and Itaborai municipal and state-run school students who are trained to collect and analyse the Guapiaçu, Macacu and Caceribu river waters. Water sampling (physical, chemical and biological elements in the water) takes place at 12 different sites both upstream and downstream urban areas of the referred rivers.
Covid-19 pandemic outbreak at the beginning of the year forced this programme to be held online with no water sampling trips organized. In October, the project team reinstated the latter following strict guidelines from health agencies including the use of personal protective equipment and working with small groups. The reinstated water sampling trip was carried out at point 7, in Boca do Mato neighbourhood which is located upstream Cachoeiras de Macacu town. Students were able to learn about benthic macroinvertebrates, which are water quality bioindicators.
Water sampling awakens a new approach to water use in young people in addition to being a very different and fun activity. 45 Environmental Monitors in Cachoeiras de Macacu were trained and are now ready to assist Guapiacu III project team in this programme. Guapiacu III project is currently starting the on-line Itaborai municipality school students´s recruiting process.
The Guapiaçu Grande Vida (GGV II) Petrobras funded forest restoration and environmental education project has now come to the end, after two more productive years at REGUA. Here is a summary of the main achievements:
Forest restoration: In the GGV II area, 60 hectares of degraded areas were replanted between 2017-2019, with 120,000 native trees of 181 different Atlantic Forest species. Together with the 100 hectares planted with 180,000 trees by the GGV I project between 2013-2015, a total of 160 hectares have now been reforested with 300,000 saplings grown in our nursery from seeds collected on the reserve. Replanting these areas has created forest corridors between the remaining forest fragments, that are vital if biodiversity is to thrive and recover.
As part of the restoration scheme, growth and biomass counts in the previously planted GGV I area and the GGV II area were established. The GGV I area was monitored, concentrating efforts on weeding, leafcutter ant control, tree replanting and fertilizer soil enrichment. Monitoring across the whole 160 hectares planted provided the base on which to evaluate the effectiveness of the restoration and allowed for carbon sequestration analysis of the GGV I area after four years since it was planted. REGUA’s rangers, as well as both agriculturalists and land owners (totalling 32 participants), were trained to implement forest restoration methodology.
Environmental education: As part of the environmental education strategy, a water quality monitoring protocol was implemented in the Guapi-Macacu watershed. 52 Cachoeiras de Macacu secondary school students were selected and trained to collect 300 water samples at four different sites along the Guapiaçu, Macacu and Boa Vista rivers (upstream and downstream of villages and towns). In addition, a very instructive publication, Methodology and Water Quality Monitoring Results, was produced.
School visitation programme: This programme aimed at strengthening visitation to the new Grande Vida educational trail. The first 400 metres of the trail have been adapted to host the physically handicapped visitors.
The GGV school visitation programme funded children’s transport to REGUA and the Sharing Nature environmental education approach was implemented for students (primary and secondary school levels) to experience proximity to nature. Over 4000 students visited REGUA between 2017-2019. The GGV team held two teacher training courses, which allowed teachers to make the best educational use of the Grande Vida trail. A trail guiding course was also organized for 22 participants which enabled them to acquire knowledge on Cachoeiras de Macacu’s sustainable use of its natural beauties.
At the end of December 2019 the Petrobras Socio-Environmental Program grant was finally signed, and in January 2020, the GGV project, now renamed the Guapiaçu Project, started its activities. We have another two very busy years ahead of us (2020-2022), continuing the forest restoration within the upper Guapiaçu watershed, and developing the environmental education activities within Cachoeiras de Macacu and the neighbouring Itaborai municipalities.
