Abstract(s)
A Região Mediterrânica tem enfrentado um agravamento e intensificação dos períodos de seca além da diminuição da precipitação. Nesse contexto, em 1/07/2022, foi implementado, o Programa +Solo +Mais Vida: Adaptação e Mitigação das Alterações Climáticas e Luta contra a Desertificação. O programa, com duração de 22 meses, foi desenvolvido numa área de 94 hectares no Parque Natural do Vale do Guadiana, e tinha por objetivo impulsionar a adaptação às alterações climáticas e o combate à desertificação dessa região através da adoção de 10 boas práticas agrosilvopastoris de combate a degradação do solo. As medidas que caracterizaram o programa foram: biodiversidade funcional, controle da erosão e aumento da infiltração, economia circular e carbon farming, gestão adaptativa do pastoreio, melhoramento de solo, melhoria do mosaico mediterrânico, pastagens permanentes, promoção da regeneração natural, restauro de linhas de água e retenção e conservação de água na paisagem. O intuito da dissertação, apresentada a seguir, foi desenvolver uma análise econômica das tecnologias de produção, e boas práticas inseridas nesse programa, buscando compreender seus resultados e oferecer aos agricultores uma ferramenta que auxilie a sua tomada de decisão. Foi possível observar, de forma imediata, os custos referentes à implementação de cada tecnologia e dados relativos à emissão de carbono das atividades anuais e dos investimentos (sementeira direta e convencional de pastagens, protetores de regeneração, implementação de bosquetes e restauro de linha de água); também se estabeleceu uma comparação entre a tecnologia de sementeira direta e convencional, onde ficaram claras as vantagens econômicas e ambientais da primeira.
The Mediterranean Region has faced worsening and intensifying drought periods in addition to decreasing precipitation. In this context the Program +Solo +Mais Vida: Adaptation and Mitigation of Climate Change and Fight against Desertification emerged on 1st July, 2022. The program, lasting 22 months, was developed in an 94 hectares of the Parque Natural do Vale do Guadiana and aimed to boost adaptation to climate change and combat desertification in this region through the adoption of 10 good agricultural and livestock practices to combat soil degradation. The set of measures which characterized the program, will be detailed below: functional biodiversity, erosion control and increased infiltration, circular economy and carbon farming, adaptive grazing management, soil improvement, improvement of the Mediterranean mosaic, permanent pastures, promotion of natural regeneration, restoration of water lines and retention and conservation of water in the landscape. The purpose of the dissertation, presented below, will therefore be to develop an economic analysis of production technologies, and the good practices included in this program, seeking to understand its results and offer farmers a tool that helps their decision-making. It was possible to immediately observe the costs of implementing each technology and data related to the carbon emissions of annual activities and investment activities (direct and conventional seeding of pasture, regeneration protectors, implementation of groves and restoration of water lines); a comparison was also established between direct and conventional seeding technology, where the economic and environmental advantages of the former became clear.
