Abstract(s)
A educação é uma ferramenta muito poderosa para moldar comportamentos atuais e
futuros. Educar para a gestão sustentável da água é da maior relevância, sobretudo
em zonas onde este bem indispensável é frequentemente escasso. Este trabalho
realizou-se em 2021, na Escola Básica 2,3 João da Rosa, Olhão, e teve como objetivo
geral, sensibilizar e treinar os jovens para o uso eficiente da água, para a redução do
uso de plásticos e para a importância da redução das emissões de carbono. Foram
realizadas ações pedagógicas expositivas e interativas com os jovens, recorrendo às
TIC em que tiveram a oportunidade de calcular a sua Pegada Hídrica (PH) e de
observar a importância da colocação de dispositivos redutores de caudal em ambiente
escolar para evitarem desperdícios de água. Realizaram-se atividades sobre a
importância do consumo de água da torneira em detrimento de água comercializada
engarrafada, alertando para as diversas vantagens, nomeadamente explorando o
impacte ambiental das garrafas plásticas. No sentido de se estimar o balanço de
carbono desta escola, foram analisados os consumos energéticos, de gás e de água
para o funcionamento do edifício escolar e calculadas as emissões de carbono
associadas. Foram caracterizadas as espécies vegetais no espaço exterior do edifício
e avaliado o seu potencial de sequestro de carbono. Este estudo revela que a PH dos
jovens foi de 279 L e conclui-se que, se as medidas recomendadas forem
implementadas podem ser poupados 270 L/min água nas torneiras e 16 L/min nos
chuveiros. O balanço de carbono estimado evidencia que o funcionamento desta
escola é responsável pela emissão de 24 t CO2/ano. Verificou-se que há muitas
oportunidades de melhoria, que a serem implementadas nesta escola, permitiam o
seu normal funcionamento consumindo menos recursos (nomeadamente água e
energia) e reduzindo as emissões de carbono. Se os ensinamentos retirados pelos
jovens forem levados da escola para o ambiente familiar irão promover uma mudança
transversal de comportamentos sociais, que globalmente promoverão um uso mais
eficiente da água e a integração da Natureza em meio urbano, melhorando os serviços
ecossistémicos e contribuindo para a descarbonização.
Education is a very powerful tool for changing current and future behaviors. Educating for sustainable water management is of utmost importance, especially in areas with water scarcity, such as the Algarve region.This work was carried out in 2021 on Basic School 2,3 João da Rosa, Olhão, and it had as main objective to train young people for the sustainable management of water and for the reduction of plastics use and carbon emissions. For this purpose, expository and interactive actions were carried out with the students using ICT, to calculate their Water Footprint and to inform about flow-reducing devices in the school environment. Actions were prepared on the consumption of tap water, to the detriment of the consumption of bottled water, highlighting the various advantages, namely the reduction of plastics bottles. In order to estimate the carbon balance in the school building, we collected data about energy, gas and water consumption for the school’s functioning and were calculated the related carbon emissions. Vegetal species outside of the building were counted and identified to evaluate their potential for carbon sequestration. This study reveals that the PH of students was about 279 L and that can be saved 270 L/min of water on the taps and 16 L/min in the showers with the implementation of some improvement measures. The carbon balance showed that the functioning of this school is responsible for the emission of 24 t CO2/year. We founded that there are several opportunities for improvement, which allow the normal functioning of the school, consuming less water and energy and reducing the carbon emissions. If young people take good practices from school to the family will promote a transversal change in social behavior, which will globally promote a more efficient use of water and the integration of Nature in urban areas, improving ecosystem services and contributing to decarbonization.
