The environmental change by the society is recurring and has been intensified since the first civilizations. However, the lack of conservationist practices has caused the emergence of degraded areas, whose recovery is fundamental for the sustainability. In this context, this paper aims at analyzing the environmental recovery as a public policy strategy supported in the Brazilian legislation. As methodology, a documental and analytical research was developed on the regulations, discussed at a multidisciplinary perspective, from the view of legal and engineering specialists, from the agricultural and environmental areas. As a result, it was identified a collection of rules pointing at a significant commitment on the definition of guidelines. On the other hand, this meaningful quantity of legal mechanisms, associated to misalignment, may cause damages to its effectiveness. In conclusion, we can consider that environmental reclamation is widely regulated, and it represents one of the main strategies of the environmental public policy adopted in Brazil. Nevertheless, it still requires advances to combine harmoniously practical and theoretical-conceptual aspects. Thus, considering the moment that Brazil is consolidating a new Forestry Code, we hope that the achieved outcomes can contribute to the debate and mobilization about the environmental reclamation as a strategy for sustainability.

PurposeThe purpose of this paper is to analyze demand forecast strategies to support a more sustainable management in a pallet supply chain, and thus avoid environmental impacts, such as reducing the consumption of forest resources.Design/methodology/approachSince the producer presents several uncertainties regarding its demand logs, a methodology that embed zero-inflated intelligence is proposed combining fuzzy time series with clustering techniques, in order to deal with an excessive count of zeros.FindingsA comparison with other models from literature is performed. As a result, the strategy that considered at the same time the excess of zeros and low demands provided the best performance, and thus it can be considered a promising approach, particularly for sustainable supply chains where resources consumption is significant and exist a huge variation in demand over time.Originality/valueThe findings of the study contribute to the knowledge of the managers and policymakers in achieving sustainable supply chain management. The results provide the important concepts regarding the sustainability of supply chain using fuzzy time series and clustering techniques.

The urban sprawl implies in the reduction of rural production areas and increases the pressure on the natural spaces. Hence, if the urbanization does not occur properly, it can compromise sanitary conditions, biodiversity, resources and environmental services. This paper aims at presenting a mathematical model to support urban sprawl based on population dynamics, applied as a case study in the Economic Hub of the Metropolitan Region of Sorocaba - MRS. The materials corresponded to census data and urban planning parameters of the applicable law. As a result, it was found that the urban extension of Sorocaba is oversized, and that the maintenance of the current conditions and guidelines will have critical consequences, requiring a change in local politics. We conclude that the proposed model can support strategic decisions, preventing problems related to disordered growth.

O presente artigo tem a finalidade de mostrar a utilização da Lógica Fuzzy como ferramenta de inferência no suporte à decisão em análises da paisagem. Para tanto, foi criado um modelo matemático visando expressar de forma mais realista a condição ambiental da paisagem. Por meio da construção de um índice fuzzy de qualidade ambiental para a paisagem, contemplando os meios físico, biótico e antrópico, bem como critérios de ponderação (severidade, significância e magnitude), foi possível articular um método de avaliação das ações antrópicas prejudiciais ao meio ambiente, que muitas vezes são tratadas de forma subjetiva, pela presença de incertezas e ponderações pessoais...Palavras-Chaves: Paisagem; Fuzzy; Rio Jundiai-Mirim.

This study investigated the influence of land use on water quality parameters in the subtropical basin of Jundiaí-Mirim river. Water samples were collected to measure nutrients concentration and direct measurements by multiparameter probe were performed, as well as landscape analysis, using satellite images and visits in the sampling sites, besides analysis of population density data. Data were standardized and the correlation between the variables was measured using Spearman approach. Land use in the surrounding area of the sampling points had strong and significant correlations (p < 0.05) with some of the water quality parameters evaluated. These correlations had different causes, explained by the land use in a 50 m radius, or 500 m radius, or even beyond these environments studied. Landscape analysis has proved to be an important tool for understanding the interaction between water quality and land use.
