“…So, the use of science and new technologies imposed a new management of natural resources, replacing local knowledge and, thus, nature began to be dominated by man. The man aiming at profit and the conquest of markets, began to replace the management of natural resources and ecological bases through production with biological processes (Vargas, Fontoura and Wizniewsky, 2013). It should be noticed that this study is also justified by the relationship between sustainability and the agroecosystems.…”

“…The Law nº 12.651/2012 known as the "new" Forest Code enables ecological restoration with agroforestry systems, as a way for recomposing Permanent Preservation Areas (PPA) 1 and Legal Reserve (LR) 2 , which is defined from the size of the property, of up to four fiscal modules. According to Embrapa, it is possible to use the croplivestock-forestry integration (CLFI) system as a viable production alternative for the recovery of altered or degraded areas (Balbino, Barcellos, and Stone, 2011).…”

“…Nevertheless, these activities do not consider the capacity of regeneration of these natural resources, which is limited and not as fast as the degradation of the ecosystems These actions have caused many consequences in different areas of Society, such as agriculture, cattle raising, food security and other forms of production. This implicates in the soil erosion, salinization, desertification, soil contamination, riverbed's contamination, affecting mainly the agroecosystems (Vargas, Fontoura and Wizniewsky, 2013) and putting the humanity life in risk. In this perspective, the environmental education presents itself as a transformative paradigm of the social praxis, offering the modification of man in such a way that it can provide a just and solidary society.…”

The development of humanity throughout history has greatly impacted the natural resources of the Earth, jeopardizing the survival of mankind that lived for a millennium in harmony with the natural ecosystems. This paper started because of the concern that has been verified from the degradation processes of paleoagroecosystems. This study intended to analyze how the environmental education contributed as an instrument for the sustainability, standing out for the socioenvironmental sustainability. It is based on the dialectic method, and has a qualitative approach, with a descriptive and exploratory bias, constituting a bibliographic research. The results show the necessity of an increase of knowledge about the relevance of the environment education as a theory and practice, intending to sensitize the society to suppress the impacts on ecosystems and paleoagroecosystems.

“…Natural ecosystems have been increasingly impacted by the modern lifestyle of society, based on consumption and social habits that require greater natural resources (Vargas, Fontoura & Wizniewsky, 2013). Biodiversity conservation is fundamental to the environmental balance and maintenance of so-called ecosystem services, characterized by the supply of goods and services generated by natural components that contribute to human sustainability.…”

ResumoA percepção dos estudantes da educação básica sobre a importância dos sistemas agrícolas agroecológicos para a saúde humana e ambiental é fundamental para as mudanças de hábitos de consumo, conservação da biodiversidade local e transformação social em longo prazo. Por meio de um questionário, constituído por questões abertas e fechadas, foram analisadas as percepções sobre os sistemas agrícolas agroecológicos e convencionais de produção, de 360 estudantes concluintes da educação básica, residentes em nove Regiões Funcionais de Planejamento do sul do Brasil. Utilizamos categorias de classificação para respostas dentro de Research, Society and Development, v. 9, n. 4, e04942784, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i4.2784 2 eixos temáticos, expressas em porcentagens e analisadas por meio de testes Qui-quadrado e Kruskal-Wallis. De maneira geral, os estudantes reconhecem os sistemas agroecológicos como mais saudáveis para as suas famílias e para a conservação do solo e da água, principalmente por não utilizar agroquímicos. Entretanto, apresentaram dificuldades em argumentar a sua importância para a conservação da biodiversidade, dos ecossistemas e para a garantia da segurança alimentar das populações. A televisão foi a principal fonte de informação referente a agroecologia, principalmente para os estudantes residentes no meio rural, apontando com isso falhas da educação básica quanto a abordagem do tema nas escolas.Os resultados mostram a necessidade de construir uma complexa rede de conhecimentos e discussões sobre os sistemas agrícolas agroecológicos na educação básica de ensino, que impliquem nas mudanças das percepções dos estudantes, comportamentos e em escolhas sustentáveis.

AbstractThe perception of a basic education of the importance of agroecological agricultural systems for human and environmental health is fundamental for changes in consumption habits, the conservation of local biodiversity and long-term social transformation. We analyzed, by utilizing a questionnaire consisting of open and closed questions, the perceptions about agroecological and conventional agricultural production systems in 360 final students of basic education residing in nine Functional Planning Regions of southern Brazil. We used classification categories for answers within thematic axes, expressed in percentages and analyzed by means of Chi-square and Kruskal-Wallis tests. In general, students recognize agroecological systems as healthier for their families and for soil and water conservation, largely because they do not use agrochemicals. However, they demonstrated difficulties when arguing their importance for the conservation of biodiversity, ecosystems and for ensuring the food security of populations. Television was the main source of information related to agroecology, mainly for students residing in rural areas, thus pointing out shortcomings in basic education regarding the ap...

“…O manejo sustentável de um agroecossistema depende de seu nível de biodiversidade, riqueza de matéria orgânica, reposição adequada da fertilidade do solo, entre outros (GONZÁLEZ DE MOLINA; GUZMÁN CASADO, 2017), com isso, é fundamental o entendimento do uso da ocupação e papel do solo nos processos de transição agroecológica ou agriculturas de base ecológica. Nesse contexto, a agroecologia refere-se a estratégias e conhecimentos que vão além de aspectos tecnológicos ou agronômicos da produção, que necessita incorporar dimensões mais amplas e complexas, incluindo variáveis econômicas, sociais, ambientais, culturais, políticas e éticas da sustentabilidade (VARGAS et al, 2013). O agricultor familiar, costumeiramente, usa práticas que repetem aquelas usadas por seus antepassados e também aquelas que são observadas na natureza, os saberes culturais, através disso se observa a agrobiodiversidade existente em seus sistemas produtivos, por exemplo, os policultivos (RÓS et al, 2013;ALTIERI, 2018).…”

O objetivo foi avaliar o crescimento das plantas, produção de raízes de batata-doce (Ipomoea batatas) e grãos de milho pipoca (Zea mays) em sistema de cultivo solteiro e consorciado. Foram avaliadas quatro cultivares de batata-doce e uma de pipoca em blocos casualizados com três repetições em condições de campo. No cultivo solteiro, a pipoca e batata-doce foram espaçadas 75 cm entre linhas. No consorciado, o plantio da batata-doce foi no centro das entre linhas da pipoca. A adubação foi realizada com cama de frango. Aos 30, 60 e 90 dias foi avaliado o número de folhas, altura das plantas, diâmetro do colmo/baraços e comprimento de baraços. No florescimento foi determinada a matéria seca das plantas, na maturação fisiológica a produção de grãos da pipoca e aos 180, as raízes da batata-doce. Observou-se que a pipoca apresentou a maior produção de matéria seca, número de folhas, diâmetro de colmos e altura de plantas quando solteiro, as cultivares de batata-doce quando consorciadas menor produção de matéria seca e raízes, a produção de grãos de pipoca não apresentou diferença entres os sistemas de produção. O sistema consorciado de pipoca e batata-doce promove maior produção de matéria seca e produção de alimentos por área.

Intercropped cultivation of sweet potatoes and popcorn: growth and production of crops ABSTRACT: The objective was to evaluate plant growth, sweet potato productivity (Ipomoea batatas) and grains of popcorn (Zea mays) in single and intercropped systems. Four sweet potato cultivars and one popcorn in randomized blocks were evaluated with three replications in field conditions. In single cultivation, popcorn and sweet potatoes were spaced 75 cm between rows. In the intercropped, the sweet potato was in the center of between the lines of popcorn. Fertilization was carried out with chicken manure. At 30, 60 and 90 days, the number of leaves, plant height, stem/tiller diameter and tether length were evaluated. At flowering, the dry matter of the plants was determined, at physiological maturity the grain yield of the popcorn and at 180, the roots of the sweet potato. It was observed that the popcorn showed the highest production of dry matter, number of leaves, stem diameter and plant height when single, sweet potato cultivars when intercropped, lower production of dry matter and roots, the productivity of popcorn grains there was no difference between the production systems. The intercroped system of popcorn and sweet potatoes promotes greater production of dry matter and food productivity per area. Keywords: polyculture; sustainability; family farming; Ipomoea batatas; Zea mays.
