Diagnóstico ambiental de propriedades rurais: um estudo na comunidade Malhada, município do Crato - CE Coexistence with the Brazilian Semiarid region demands the guarantee and permanence of people in rural activities with dignity. Thus, small rural properties become the protagonists of the scenario for the development of family farming, based on sustainable development. However, it is necessary to see that the traditional agricultural system is still predominant. The objective for this study was then defined as the environmental diagnosis of four rural properties in the Malhada community, in Crato – CE. The methodology involved literature review; photographic records, and field observations. Data were obtained from field research with application of interviews having as a sample the four representatives of family properties. The results identified that the practices and actions adopted in rural family farming activities contribute to the contamination of surface and underground waters, and to the decrease in the productive capacity of soils, with regard to the use of chemical inputs. It was found that the conduct of farmers regarding the purchase, handling and application of agrochemicals, as well as the final destination of packaging and solid waste in general is a failure. Domestic sewage is released into the ground in a precarious way and susceptible to contamination. Surface water reservoirs such as the Rio Carás and dams were identified to help during the dry season. It is concluded that the diagnostic data revealed the need for a fundamental environmental planning to guide strategies to minimize the effects of degradation of the local ecosystem on the behavior and anthropic interferences, in the perspective of the human-nature relationship.

Plataforma online de caráter didático destinada ao dimensionamento de sistemas de microgeração fotovoltaica This study presents the development of a web-based software designed to automate the sizing of photovoltaic microgeneration systems. The tool features intuitive interfaces and accessible language, aiming to enable users without prior technical knowledge to carry out the sizing process, while also serving as a didactic resource. The software development was grounded in both technical and practical knowledge of photovoltaic technology, as addressed in specialized literature and scientific publications, which provided the theoretical foundation – especially regarding the mathematical models employed and the educational approach adopted in the project. The methodology is characterized as applied, qualitative-quantitative, and bibliographic research, focused on the educational automation of photovoltaic system sizing, based on technical, scientific, and academic sources. As a result, a fully functional version of the software was developed, capable of automating the sizing process through responsive and user-friendly interfaces, suitable for both desktop and mobile devices. The application seeks to convey the sizing process in an educational and accessible manner, reaching a broad audience and promoting photovoltaic technology along with its social and environmental benefits. Through interactive interfaces, illustrative visual elements, and clear language, the software has the potential to be used as a didactic tool in academic contexts, while also contributing to the feasibility of residential photovoltaic microgeneration, encouraging distributed generation as a sustainable alternative. Given that similar software solutions currently available require specialized technical knowledge, the developed software stands out as innovative by combining automated sizing with an integrated learning experience and high usability, thereby expanding access to users of diverse profiles.

Os instrumentos de gestão ambiental no Rio Grande do Norte: uma análise sob a ótica do planejamento The ongoing environmental transformations highlight the importance of organizations and federal entities creating changes in their scope to incorporate measures that have a lesser impact on nature. At the state and municipal level, swift and responsive environmental management is one of the main alternatives for protecting and caring for natural resources and local biodiversity. Therefore, this study aims to analyze how municipal planning instruments contribute to strengthening environmental management in Rio Grande do Norte. The state's municipalities have six planning instruments; their integration and implementation promote the economic, social, and sustainable development of local governments. The study focused on the Institute for Sustainable Development and the Environment of Rio Grande do Norte (IDEMA/RN) and the municipalities of Rio Grande do Norte. Methodologically, to achieve the established objectives, a qualitative method was used in the form of a case study; furthermore, the research is characterized as applied, with an exploratory and descriptive approach. From this perspective, this study addressed the main environmental management laws, the relationship between the Rio Grande do Norte state environmental agency and municipalities, and the instruments used to foster and shape environmental management in that state. The results revealed that Rio Grande do Norte municipalities possess a significant portion of the planning instruments, but they face challenges related to human resources and conflicts of interest. Furthermore, licensing, which is one of the most important environmental management tools, is implemented by few municipalities, generating numerous negative impacts. Furthermore, the results of the work carried out by the state environmental agency reflect the lack of structure within municipal environmental departments. The conclusion is that the state needs to increasingly develop public policies and laws that create greater rigor in the use of these instruments by municipalities; furthermore, there should be greater investment in trained professionals to work in local environmental management. It is expected that the rules and regulations on environmental matters, according to the natural specificities of the state, can be improved taking into account their potential, so that there is in fact sustainable development in RN.
