Embora a Gestão Municipal de Resíduos Urbanos seja amplamente abordada a nível nacional, estudos que contribuam para a Gestão de Resíduos Urbanos (GRU), em subdivisões administrativas, ainda são limitados. Esta investigação é um estudo retrospetivo da região do Algarve, para o período 2014-2018, sobre os efeitos da estrutura e da conjuntura regionais na GRU. Ao nível estrutural, analisou-se o modo como a população e o setor do turismo influenciaram a GRU e conjunturalmente, a forma como influenciaram as atividades económicas e os negócios instalados na região. Devido às suas características geográficas e condições edafoclimáticas, a região Algarvia adquiriu estatuto de principal região turística de Portugal. Ao longo dos anos, esta atividade tornou-se cada vez mais especializada e a economia regional cada vez mais direcionada para suprir as necessidades deste setor. Todavia, atividades como a GRU enfrentam desafios que não se colocam noutras regiões, existindo continuadamente necessidades de adaptação. Portanto, conhecer comportamentos, tendências e as variáveis que influenciam a GRU, permitirá definir estratégias futuras que possibilitarão a melhoria da performance operacional das entidades gestoras, a redução de custos, o cumprimento de metas e a mitigação de impactos ambientais, beneficiando a atratividade da região. Estas circunstâncias manifestam-se cruciais nos processos de tomada de decisão, de tal forma, que se revela, cada vez mais necessário a produção de informação estratégica para orientar futuros processos organizacionais, designadamente no que concerne a uma GRU mais eficiente e sustentável. Assim, este trabalho, para os dezasseis municípios do Algarve, utilizou a Análise de Dados de Três-Vias, designadamente o método COSTATIS (Thioulouse, 2011), para produzir um diagnóstico, para o período 2014-2018, que avaliasse, ao longo do espaço e do tempo, a estabilidade da relação entre a População, o Turismo e a Economia Regional e a GRU. Julgamos que, com esta abordagem, seja possível auxiliar o processo de tomada de decisão e, assim contribuir, não somente para uma GRU mais eficiente, como também para a sustentabilidade ambiental da região.
Although Municipal Solid Waste Management is widely addressed at national level, studies that contribute to Solid Waste Management (SWM), in administrative subdivisions, are still limited. This investigation is a retrospective study of the Algarve region, for the period 2014-2018, on the effects of the regional structure and conjuncture on the SWM. At the structural level, it was analyzed the way the population and the tourism sector were reflected on the SWM and conjuncturally, the way they influenced economic activities and the businesses installed in the region. Due to its geographical characteristics and edaphoclimatic conditions, the Algarve region has acquired the status of the main tourist region in Portugal. Over the years, this activity has become increasingly specialized and the regional economy increasingly directed towards suppressing the needs of this sector. However, activities such as the SWM face challenges that do not arise in other regions, and there are continuous needs for adaptation. Therefore, knowing behaviours, trends and the variables that influence the SWM, will allow defining future strategies that will facilitate the improvement of the operating performance of the management entities, the reduction of costs, the fulfilment of goals and the mitigation of environmental impacts, benefiting the attractiveness of the region. These circumstances are crucial in the decision-making processes, in such a way that the production of strategic information is increasingly necessary to guide future organizational processes, namely with regard to a more efficient and sustainable SWM. Thus, this work, for the sixteen municipalities in the Algarve, used the Three-Way Data Analysis, namely the COSTATIS method (Thioulouse, 2011), to produce a diagnosis, for the period 2014-2018, that evaluated, over the space and time, the stability of the relationship between Population, Tourism and the Regional Economy and the SWM. We believe that, with this approach, it is possible to assist the decision-making process and thus contribute, not only to a more efficient UWM, but also to the environmental sustainability of the region.
