This article aims to deepen the discussion about agricultural activity in metropolitan cities. Our analysis focuses specifically on the Fortaleza Metropolitan Area (FMA), State of Ceará, Brazil, and allows us to further understand family farming in that area. For this purpose, we reviewed a set of primary and secondary data regarding the profile of the producers and agricultural and food processing establishments in the metropolitan area under analysis. This multifaceted approach helped us identify key issues related to production and food systems in the FMA, and showed the importance of a research agenda focused on evaluating the potential of family farming in this specific context. This study presents the production strategies adopted, the challenges faced and the opportunities identified by family farmers. Discussing agriculture in metropolitan areas help us connect socio-spatial and socio-environmental problems, in addition to enabling us to suggest the development of cross-sectoral public policies. By offering a comprehensive overview, this study aims to contribute to effective policy making, promoting the sustainability and resilience of family farming in metropolitan contexts. We hope that the reflection on agriculture developed in such areas and its characteristics in local and metropolitan scenarios will be helpful to researchers, managers and those responsible for the implementation and execution of public policies, as well as other agents and entities interested in family (and urban) agriculture.
本文旨在加深对大都市农业活动的讨论。我们的分析特别关注巴西塞阿拉州福塔莱萨大都市区(FMA),使我们能够进一步了解该地区的家庭农业。为此,我们查阅了有关所分析大都市区的生产者、农产品和食品加工企业概况的一系列一手和二手数据。这种多层面的方法帮助我们确定了与食品加工区的生产和食品系统相关的关键问题,并表明了研究议程的重要性,该议程的重点是评估家庭农业在这一特定环境中的潜力。本研究介绍了家庭农场主采取的生产战略、面临的挑战和发现的机遇。讨论大都市地区的农业问题有助于我们将社会空间问题与社会环境问题联系起来,并为制定跨部门的公共政策提供建议。通过提供一个全面的概述,本研究旨在为有效的政策制定做出贡献,促进大都市背景下家庭农业的可持续性和恢复力。我们希望,对在这些地区发展的农业及其在地方和大都市环境中的特点的思考,将对研究人员、管理人员、负责实施和执行公共政策的人员以及对家庭(和城市)农业感兴趣的其他代理人和实体有所帮助。

Este texto objetiva ampliar as discussões em torno da atividade agropecuária em municípios metropolitanos. Nossa reflexão recai especificamente sobre a Região Metropolitana de Fortaleza, no Ceará, e nos permitiu avançar no entendimento da sua agricultura familiar. Para isso, analisamos um conjunto de dados primários e secundários a respeito do perfil do produtor, dos estabelecimentos agropecuários e da produção de alimentos na região metropolitana em análise. Essa abordagem multifacetada nos ajudou a identificar questões-chave relacionadas à produção e aos sistemas alimentares na RMF, bem como mostrou a importância de agenda de pesquisa que busque avaliar o potencial da agricultura familiar nesse contexto específico. A pesquisa menciona as estratégias de produção adotadas, os desafios enfrentados e as oportunidades identificadas pelos agricultores familiares. Discutir a agricultura nos espaços metropolitanos pode articular várias lutas de natureza socioespacial e socioambiental, além de sugerir a elaboração de políticas públicas intersetoriais. Ao oferecer uma visão abrangente, este estudo visa informar a formulação de políticas eficazes, promovendo a sustentabilidade e a resiliência da agricultura familiar em contextos metropolitanos. Esperamos que a reflexão sobre as agriculturas realizadas neste espaço e sua caracterização em contextos municipais e metropolitanos, seja útil aos pesquisadores, gestores e operadores de políticas públicas, bem como demais agentes e instituições interessados na agricultura familiar (e urbana).
本文旨在拓宽对大都市农业活动的讨论。我们的思考特别关注塞阿拉州福塔莱萨大区,这使我们能够加深对家庭农业的理解。为此,我们分析了有关所分析的大都市地区的生产者、农业机构和食品生产概况的一系列一手和二手数据。这种多层面的方法帮助我们确定了与马其顿共和国粮食生产和粮食系统相关的关键问题,并显示了研究议程的重要性,该议程旨在评估家庭农业在这一特定环境中的潜力。研究提到了家庭农场主采取的生产战略、面临的挑战和发现的机遇。讨论大都市空间中的农业可以阐明各种社会空间和社会环境性质的斗争,并建议制定跨部门的公共政策。通过提供一个全面的视角,本研究旨在为制定有效的政策提供信息,促进大都市背景下家庭农业的可持续性和恢复力。我们希望,对这一空间中的农业及其在城市和大都市背景下的特征进行反思,将对研究人员、公共政策的管理者和操作者以及对家庭(和城市)农业感兴趣的其他代理人和机构有所帮助。

In Southeastern Brazil, artisanal fishing communities reside, operate and suffer from interference originating from various economic branches. Thus, this study is aimed at identifying the critical points concerning the practice of artisanal fishing from the traditional knowledge of artisanal fishers in the coastal mesoregion of ES. 102 ethnographic interviews were conducted in 2022 with artisanal fishers through a semistructured questionnaire containing both open and closed questions. The critical points of fishing were identified through a SWOT analysis (strengths, weaknesses, opportunities, and threats). All the participants were men (n=102; 100%), and they reported that negative critical points (weaknesses and threats) exert the greatest influence on fishing. From the perspective of these fishers, the main problems that interfere with artisanal fishing are the lack of adequate fish storage, the precariousness of the vessels, the reduction in fish stocks, the high perishability of fish, the devaluation of traditional knowledge, and the presence of middlemen that prevent the commercialization of fish production from moving directly from the fisher to the final consumer. The identification of these critical points enables the recognition of flaws in the production chain and the realization that they can be minimized through public policies and comanagement strategies related to the economic, ecological, and social development of the sector.
在巴西东南部,手工捕鱼社区居住、经营并受到来自不同经济部门的干扰。因此,本研究旨在从 ES 沿海中间地带手工捕鱼者的传统知识中找出有关手工捕鱼实践的关键点。2022 年,通过一份包含开放式和封闭式问题的半结构化问卷,对个体渔民进行了 102 次人种学访谈。通过 SWOT 分析(优势、劣势、机会和威胁)确定了捕鱼的关键点。所有参与者均为男性(n=102;100%),他们表示负面关键点(弱点和威胁)对捕鱼的影响最大。从这些渔民的角度来看,干扰手工捕鱼的主要问题是缺乏足够的鱼类储存、船只不稳定、鱼类资源减少、鱼类极易变质、传统知识贬值,以及中间商的存在阻碍了鱼类生产的商业化,使其无法直接从渔民转向最终消费者。确定这些关键点有助于认识到生产链中的缺陷,并认识到可以通过与该行业的经济、生态和社会发展有关的公共政策和共同管理战略将这些缺陷降至最低。

Abstract Water management in the Brazilian semi-arid region has been, for decades, a challenge for institutions and decision-makers due to its intrinsic characteristics. The density of human occupation makes the region very vulnerable to drought events and problems related to the quality and need for water use are central issues. For this reason, this study presents an approach to assess the situation of water reservoirs in the semiarid based on the Water Quality Index (WQI) and Multi-Criteria Decision Making (MCDM). The WQI was used to calculate water quality and later applied as a criterion for the MCDM model proposed. The model also considers the need and availability criteria to assess the reservoirs of the two largest drainage basins in Rio Grande do Norte state, Brazil. The MCDM method used was R-TOPSIS since it is more flexible and robust for future analyses in other situations. The results showed the condition of the reservoirs, in order to support decision-makers in the operation of these facilities and enable multiple use of the waters. The combined approach proposed may provide important contributions in the analysis of water reservoirs in order to supply the semiarid region, where water issue is critical.
摘要 由于巴西半干旱地区的固有特征,几十年来该地区的水资源管理一直是机构和决策者面临的一项挑战。人类居住的密度使得该地区非常容易受到干旱事件的影响,而与水质和用水需求相关的问题则是该地区的核心问题。因此,本研究提出了一种基于水质指数(WQI)和多标准决策(MCDM)的半干旱地区水库状况评估方法。水质指数被用来计算水质,随后被用作所提议的 MCDM 模型的标准。该模型还考虑了需求和可用性标准,以评估巴西北里奥格兰德州两个最大流域的水库。所使用的 MCDM 方法是 R-TOPSIS,因为该方法更加灵活和稳健,可用于今后在其他情况下的分析。结果显示了水库的状况,以便为决策者操作这些设施提供支持,并实现水域的多重利用。所提出的综合方法可为水库分析做出重要贡献,以便为水问题至关重要的半干旱地区供水。

Sugarcane cultivation methods and processes usually have negative impacts on the environment. However, this industry has been seeking more sustainable technologies, ranging from the adequate disposal of the organic residues produced to the elimination of pre-harvest burning and introduction of mechanized harvest. The objective of this work was to verify the influence of vinasse application and mechanized harvesting on the physical and chemical aspects of a dystrophic Red Yellow Argisol of medium texture, cultivated with sugarcane. For this, a field experiment in a Completely Randomized Design, with a factorial scheme was conducted. Four management treatments, with three replications, were evaluated: T1 - Without application of vinasse, burned cane followed by manual harvest, without irrigation; T2 - With application of vinasse, mechanized harvest, without irrigation; T3 - With application of vinasse, mechanized harvest, with irrigation; T4 - With application of vinasse, burned cane followed by manual harvest, without irrigation. Soil samples were collected in three depths (0 – 20 cm, 20 – 40 cm and 40 – 60 cm) and soil physical and chemical characteristics were determined. The data obtained were submitted to ANOVA and compared by the Tukey test (p≤0.05) of probability, using the statistical program ASSISTAT 7.7 beta. The results showed that fertigation with vinasse did not influence soil density, particle density, and total porosity. However, mechanized harvesting increased soil density and total porosity. The soil in the experimental unit without vinasse application presented a more acidic pH and high levels of aluminum saturation, causing a decrease in the availability of nutrients, and the soils treated with vinasse had an increase in nutrient availability. Therefore, the addition of vinasse can be an important strategy in maintaining and increasing long-term soil fertility in sugarcane cropping systems.
甘蔗种植方法和过程通常会对环境产生负面影响。然而,甘蔗种植业一直在寻求更具可持续性的技术,包括适当处理所产生的有机残留物、取消收割前的焚烧以及采用机械化收割等。这项工作的目的是验证施用蔗渣和机械化收割对甘蔗种植的中等质地红黄壤物理和化学方面的影响。为此,采用完全随机设计的因子方案进行了一项田间试验。共评估了四个管理处理,三个重复:T1--不施用甘蔗渣,烧毁甘蔗后人工收割,不灌溉;T2--施用甘蔗渣,机械化收割,不灌溉;T3--施用甘蔗渣,机械化收割,灌溉;T4--施用甘蔗渣,烧毁甘蔗后人工收割,不灌溉。采集了三个深度(0 - 20 厘米、20 - 40 厘米和 40 - 60 厘米)的土壤样本,并测定了土壤的物理和化学特征。使用 ASSISTAT 7.7 beta 统计程序对获得的数据进行方差分析,并通过 Tukey 概率检验(p≤0.05)进行比较。结果表明,蔗渣施肥不会影响土壤密度、颗粒密度和总孔隙度。然而,机械化收割增加了土壤密度和总孔隙度。未施用蔗渣的实验单元的土壤 pH 值偏酸,铝饱和度高,导致养分供应量减少,而施用蔗渣的土壤养分供应量增加。因此,在甘蔗种植系统中,添加蔗渣是保持和提高土壤长期肥力的重要策略。

The geographical mesoregion of the Triângulo Mineiro and Alto Paranaíba has an economy strongly focused on agribusiness, with grain and sugarcane production levels that put them at the forefront of the economic and political scenario of the state of Minas Gerais, Brazil. However, scientific production focused on soil diversity in this region has long been undervalued compared to other regions of the state and country where the soils exhibit more diverse and, therefore, more intriguing geological and geomorphological characteristics. This paper aims to evaluate the evolution and spatialization of bibliographic production with the central theme of soils in the Triângulo Mineiro and Alto Paranaíba mesoregion. As such, papers from the last three decades within the municipalities of the studied region were selected from five important journals. The papers from the initial screening were analyzed for the following: the profile of the authors (gender and institutional affiliation); number of authors per paper; methods used; and distribution of these papers across the selected region. The results indicate a concentration of papers in four municipalities and a total lack of publications from another 40. Males heavily dominated scientific production in the analyzed segments. Despite the mesoregion having 11 public higher education institutions, most municipalities' soil research was incipient. Regarding the methods used by researchers, in municipalities where more institutional partnerships were made possible, there was an increase in the number of techniques and methods explored in investigating problems. Although the study area presents relative geological and geomorphological homogeneity that gives a monotonous aspect to the landscape, knowledge of its pedodiversity, and its economic significance for agriculture, justifies the need to resume soil studies in the Triângulo Mineiro and Alto Paranaíba, particularly by exploring methods and municipalities that are still little known.
米内罗河三角洲和上帕拉纳伊巴地理中间区域的经济主要集中在农业综合企业上,其谷物和甘蔗生产水平在巴西米纳斯吉拉斯州的经济和政治格局中处于领先地位。然而,与米纳斯吉拉斯州和巴西的其他地区相比,该地区的土壤表现出更多的多样性,因此地质和地貌特征也更耐人寻味,而以该地区土壤多样性为重点的科研成果却长期被低估。本文旨在评估以米内罗河三角洲和上帕拉纳伊巴中游地区土壤为中心主题的文献生产的演变和空间分布情况。因此,我们从五种重要期刊中选取了研究区域内各市在过去三十年中发表的论文。对初步筛选出的论文进行了以下分析:作者情况(性别和所属机构);每篇论文的作者人数;使用的方法;以及这些论文在所选地区的分布情况。结果表明,论文主要集中在四个市镇,另外 40 个市镇完全没有论文发表。在所分析的地区中,男性在科研成果中占主导地位。尽管中部地区有 11 所公立高等院校,但大多数城市的土壤研究都处于起步阶段。在研究人员使用的方法方面,在那些与更多机构建立了合作关系的城市,研究问题时所采用的技术和方法的数量有所增加。虽然研究地区的地质和地貌相对单一,使景观显得单调,但对其土壤多样性的了解及其对农业的经济意义,证明有必要恢复对米内罗河三角洲和上帕拉纳伊巴地区的土壤研究,特别是通过探索仍鲜为人知的方法和城市。

Nossos resultados revelam a articulação entre conhecimento tradicional e científico como elemento chave na sofisticação produtiva do QMA da Canastra, promovendo a qualificação do trabalho e a busca pelo atendimento a padrões de exigência do mercado consumidor sem romper com laços e práticas do saber-fazer local, fruto de uma relação sociedade-natureza historicamente construída. A discussão proposta é situada no âmbito de estudos empíricos sobre inovação baseada em recursos naturais na América Latina e de reflexões em torno de sistemas territoriais de inovação (STI), que leva em consideração uma perspectiva multiescalar do processo inovativo que tem vigorado em estudos no campo da Geografia do Conhecimento e da Inovação. Apesar dos avanços constatados, salientamos que a estruturação do QMA da Canastra ainda enfrenta obstáculos com fragilidades estruturais típicas de STI periféricos. Almejamos que os resultados possam contribuir não apenas para a compreensão da região produtiva do QMA da Canastra, mas que possa ser um material de apoio para políticas de inovação que consideram a necessidade de um olhar para a realidade das regiões.
本文的目的是认识创新在 Canastra 的米纳斯手工奶酪生产取得成功中的作用。研究方法包括文献综述、文献调查、实地研究和访谈。我们的研究结果表明,传统知识和科学知识之间的衔接是卡纳斯特拉 QMA 生产先进性的一个关键因素,它促进了劳动力素质的提高,并在不破坏当地专有技术的纽带和实践的情况下,满足了消费市场的苛刻标准,这是历史上构建的社会与自然关系的成果。拟议的讨论是在对拉丁美洲基于自然资源的创新进行实证研究和对地域创新系统 (STI)进行思考的范围内进行的,其中考虑到了创新过程的多尺度视角,这种视角在知识 与创新地理学领域的研究中一直有效。尽管取得了一些进展,但我们仍要强调,卡纳斯特拉地区创新体系的构建仍面临着一些障碍,这些障碍具有典型的外围科技创新的结构性弱点。我们希望,这些成果不仅有助于了解卡纳斯特拉农业区的生产区域,还有助于为考虑到区域现实需要的创新政策提供支持。
