This study aims to analyze the influence of the El Niño (EN) and La Niña (LN) phenomena on floods in the state of Espírito Santo (ES), using flow rate data, rainfall records, and synoptic system analyses in the region. The evaluation to be conducted is particularly relevant due to the nature of EN and LN phenomena, which result from ocean-atmosphere interactions and exhibit significant predictability. Advanced knowledge of these phenomena can serve as a foundation for developing strategies for both urban planning and disaster prevention. For the flood-related analysis, flow rate data from hydrological stations on the state’s main rivers were considered, along with precipitation information and synoptic analysis through charts and satellite imagery. The findings indicate that La Niña influences increased precipitation in Espírito Santo and in the regions of neighboring states whose rivers contribute water discharge to Espírito Santo’s rivers. The studied cases suggest that La Niña modulates the South Atlantic Convergence Zone (SACZ), shifting it northward from its climatological position and intensifying rainfall in Espírito Santo, causing floods. Investments in advanced early warning technologies and meteorological monitoring, such as those provided by CPTEC, the Brazilian Navy, and the National Institute of Meteorology (INMET), can play a crucial role in providing information about the impact of these climatic phenomena, enabling the prediction of extreme rainfall patterns and floods. When integrated into urban planning and land management processes, this information allows for a more effective and coordinated response to flood threats, enabling the implementation of appropriate preventive and adaptive measures

The water resources plan is based on the triad of participation, integration and decentralization. The basis of this plan is the diagnosis and the prognosis of scenarios elaborated by means of the compilation and systematization of data and information on the hydrographic basin. The objective of this work is to structure a collaborative communication and information to subsidize a water resources plan, based on the survey of Environmental Perception (PA) of the Hydrographic Basin Committee (CBH) and key actors. Through a case study, a collective communication plan was constructed, aiming to gather actions and efforts to add value and consolidate the information seeking a clear, concise and validated language that qualifies the institution and the public for the planning process of the bowl. Using the qualitative quantitative approach, basin data and the characterization of CBH members were produced. Based on this knowledge construction, a database and information was obtained from the territory and from these social actors. Through a participatory workshop, we identified the communication processes regarding: communication tools, frequency, language, content and message / content communicators, accessibility, transparency, integration and interactivity. The constructed database was analyzed by means of triangulation of methods, and using the SWOT matrix to subsidize the structuring of the plan. The results of these two procedures were organized, systematized and presented again to the social actors (CBH and key actors) for other contributions and validation. It is observed that the collective structuring of the communication and information plan provides a viable strategy to communicate the local knowledge captured by environmental perception. It also identifies the flow of information and knowledge about the basin, consolidates the communication processes of the CBH, favors and broadens the dialogue among the members of the committee, and consequently strengthens these actors in the actions of planning and management of the river basin

Agroforestry systems (SAFs) provide a range of hydrological ecosystem services associated with natural forest cover. For these reasons, the adoption of agroforestry systems is encouraged in different countries and is applied, for example, in projects and programs to promote the restoration of landscapes and sustainable development, such as Reflorestar, the reforestation program in Espírito Santo. However, on one hand, there is a lack of studies that investigate and quantify the impacts of agroforestry systems on the components of the hydrological cycle of the river basins and, on the other, the need to disseminate knowledge and perceive the benefits associated with these systems so that the restoration of forest landscapes can be spread throughout the territory. In this context, the present work seeks to evaluate the influence of SAFs on the hydrological condition of hydrographic basins, through indicators obtained from variables of the SWAT model, aiming to increase the knowledge about the adoption of these systems on water availability. The scenarios simulated were: a) increase in forest cover by SAFs; and b) different arrangements of the systems, based on the plant typologies in the study area. As the defined indicators of the hydrological condition were: the fraction of the precipitation that contributes to the river flow (𝑊𝑌𝐿𝐷/𝑃𝑅𝐸𝐶); contribution of groundwater to river flow (𝐺𝑊𝑄/𝑊𝑌𝐿𝐷); contribution of lateral flow to river flow (𝐿𝐴𝑇𝑄/𝑊𝑌𝐿𝐷); contribution of the surface runoff to the river flow (𝑆𝑈𝑅𝑄/𝑊𝑌𝐿𝐷) and the fraction of rainwater percolated to feed shallow and deep aquifers(𝑃𝐸𝑅𝐶/𝑃𝑅𝐸𝐶). The study showed a greater influence of the SAFs on the underground dynamics, with increased recharge of shallow and deep aquifers, as well as increased contribution of the base flow to the river flows, for scenarios of adoption of up to 42% of SAFs. The contribution of surface runoff to flow rates reduced by up to 22% with the increase in the area of adoption of SAFs. The variations were less significant regarding the different arrangements of SAFs, however, the results indicated that scenarios with predominance of medium and high strata caused a greater change for the indicators evaluated. Therefore, the increased SAFs’ coverage had an influence on the hydrological condition, especially on groundwater dynamics and surface runoff. The contribution to the flows was maintained over the timeframe. In addition, the SWAT model proved to be a tool capable of assisting in the evaluation of the effects of adopting SAFs for the provision of ecosystem services, contributing to greater knowledge about the hydrological benefits associated with these systems, with potential subsidies to the policies to increase the forest cover.

Modelo conceitual para sistematização e avaliação de indicadores de sustentabilidade para sistemas agroflorestais no contexto da gestão de recursos hídricos
(Universidade Federal do Espírito Santo, 2019-07-19) Machado Júnior, José de Aquino; Buarque, Diogo Costa ; https://orcid.org/0000-0003-2698-520X; http://lattes.cnpq.br/8616432679482558; Teixeira, Edmilson Costa ; https://orcid.org/0000-0001-7535-8689; http://lattes.cnpq.br/2223526989758235; https://orcid.org/0000-0002-1296-6510; http://lattes.cnpq.br/4675072098126067; Reis, José Antonio Tosta ; https://orcid.org/0000-0001-9916-1469; http://lattes.cnpq.br/7828468159099998; Sossai, Marcos Franklin ; https://orcid.org/; http://lattes.cnpq.br/5566667702204394
In recent years, forest recovery has been one of the main activities in watershed management, since its use can promote environmental improvements in the hydrological cycle as well as socioeconomic enhancements thus helping in sustainable territorial development. In this context, the use of Agroforestry Systems - SAFs is one of the main forest recovery strategies, because they are considered more sustainable than others forest cover and in addition, they are an alternative to the intensive production systems. In spite of the importance of the SAFs in the forest recovery theme, in general, the studies that consider the sustainability assessment do not contemplate many aspects/factors that could influence their application by potential rural producers. Due to the benefits of these systems this work aimed at enlarging knowledge about factors associated with their sustainability, as well as to establish guidelines for the improvement of its application. Therefore, a literature review was carried out as well as an observation of the State Program for Increasing Forest Coverage - Reforestation and the State Policy for Water Resources of Espírito Santo. Then these data were related to the SAFs by the use of a technic based on the methodological framework titled "Sustainability of Agriculture and Natural Resources - SARN ", a conceptual model was developed for the systematization and evaluation of sustainability indicators for SAFs. As a result, 98 indicators were obtained and systematized in levels of descriptors, significant elements, significant categories and evaluation dimensions, the distribution by dimension were: Environmental - 40 indicators (41%); Sociocultural - 28 indicators (29%); Economic -18 indicators (18%) and Political Institutional - 12 indicators (12%). The proposed structure for the systematization of the indicators provides a qualitative and systemic evaluation of the sustainability of the resources and the operations involved in the SAFs that subsidises guidelines for improving the use of SAFs in different situations in the watersheds. Most of the indicators are quick implementation and not onerous as well as they depend on direct visual evaluations and interviews. For the minority of the indicators more calculus and a complex laboratory analyzes will be needed
