Environmental issues continue to be on a growing agenda around the world. A large part of the global concerns is focused on the Amazon, even though it leaves aside almost the entire human contingent that inhabits that space. Except for the Indians. They disregard that many of the harmful environmental impacts are practiced by family farmers because fire is their greatest technology and, in many cases, the only one. Therefore, the management of this territory must create mechanisms and instruments capable of promoting the region's sustainable development, bringing together environmental and social interests, which only can be done through laws. The Rural Environmental Registry (CAR, acronym in Portuguese) aims to implement sustainable public policies. Thus, this literature review study aims to show CAR's contribution to family farmers operating in the State of Amazonas from a legal and environmental point of view. The results show that a) it is necessary to know the main legal aspects of the CAR to understand its environmental importance, b) knowing each of the steps in the preparation of the registry allows this instrument to fulfill its environmental mission as a result of legal discipline, c) the simplification of the regime granted to family farmers and similar populations allows the legal requirements to be fulfilled by this essential human contingent in the Amazon and d) the rigorous execution of the CAR allowed for several conflicts of overlapping rural areas to be resolved, which benefited family farmers and populations equivalent, pioneers in these areas. The conclusion states that implementing the Brazilian forest code is essential for family farming agribusiness, requiring technical support. The CAR emerges as a fundamental instrument.

Embora seja um tema considerado relevante, o meio ambiente ainda é tratado de forma insuficiente e ineficaz na escola. A educação ambiental é uma poderosa aliada no cuidado e na preservação do meio ambiente, porém, poucas pessoas têm acesso a esse tipo de informação, o que dificulta a formação de cidadãos com consciência e responsabilidade ambiental. Por isso, após algumas reuniões com educadores e estudantes, será desenvolvida uma cartilha didática e funcional, com linguagem de fácil compreensão, com o objetivo de introduzir a educação ambiental e seus principais aspectos no ensino fundamental, buscando formar cidadãos conscientes de seus deveres e direitos para com o meio ambiente. Além de favorecer o diálogo em casa, com os pais, permear temas como a legislação ambiental, e as sanções em caso de descumprimento, disseminando assim o conhecimento adquirido. Para que a criação da cartilha seja possível, serão realizadas algumas visitas para diálogo e palestra com os educadores e uma reunião com os alunos para realizar o estudo do Direito Ambiental, com o auxílio do material que será confeccionado. O nível de satisfação e eficácia com o projeto executado será avaliado após um debate com os alunos, que estarão muito mais conscientes e preocupados com a legislação que protege o meio ambiente.

Agroforestry systems are frequently regarded as productive alternatives capable of reconciling agricultural production and environmental conservation, yet their associations with water–energy–food (WEF) Nexus dimensions remain insufficiently explored in the Amazon. This observational and exploratory study examined territorial patterns and associations among indicators of AFS, monocultures, and municipal water, energy, and food conditions in Northern Brazil. Secondary data from 70 municipalities were analyzed using Principal Component Analysis, Pearson correlation, and linear regression with state fixed effects. The analyses were designed to identify associations rather than causal effects. The first two principal components explained 85.1% of total variance. PC1 (51.3%) was primarily defined by water and energy indicators, whereas PC2 (33.8%) was dominated by vulnerability to food insecurity. Associations between production-system indicators and Nexus components were predominantly weak. A negative and statistically significant association was observed between the log-transformed mean AFS area indicator per 1,000 rural inhabitants and PC1 (b = -0.28; p = 0.033), while the corresponding monoculture indicator was not statistically significant. The results also show that food vulnerability forms a relatively independent dimension. Overall, the findings indicate that territorial heterogeneity is an important feature of the observed WEF Nexus configuration, beyond the associations identified with production-system indicators.
