“…As any committee of that system, it is expected to allow social actors "to act, in principle, having a directive on their role, responsibilities and attributions in order to neutralize predatory practices oriented by economic or political interest", according to Jacobi, Cibim and Leão (2015, p. 36); but, in the case of the Upper Tietê committee, "this does not happen, since we note a fragile capacity to organize and mobilize civil society". About that committee, studies have shown "a very complex picture, mainly with regard to the little effectiveness of the decisions and the representation of the civil society" (JACOBI; CIBIM; LEÃO, 2015, p. 36), despite the fact that national and state law place it in the centre of the decision-making process (JACOBI et al, 2013;SOUZA, 2016).…”

Brazilian river basin committees are a democratic innovation increasingly studied throughout the world as a positive example of water governance, with some limitations. In our two-year research project (2018-2020), we aimed at activating, preserving and circulating narratives and stories from the participation of the various social, economic and political actors in the Upper Tietê River Basin Committee (São Paulo), in order to gather organisational memories. Our interview data bring lessons applicable to contexts with similar governance systems and others beyond, by suggesting how democratic, participatory arrangements can be improved as strategies that a society can explore in the process of learning how to cope with the effects of climate change, including the threat of water scarcity that grew in the metropolitan region of São Paulo after 2014. Interviews point to the need to clarify the roles of the committee and its members before society, to strengthen authority and legitimacy.

“…De 2003 a 2016, mais de 2.780 municípios decretaram estado de calamidade pública ou situação de emergência devido às constantes estiagens, sendo que 78% de toda região Nordeste do Brasil foi afetada e, de 2013 a 2016, esse número era de 83% (Ana, 2017). No final do ano de 2013, a população da maior cidade da América Latina foi surpreendida com uma iminente crise no abastecimento de água, especialmente na região metropolitana de São Paulo (Figura 4) (Jacobi et al, 2015).…”

“…A falta de regulação do uso da água em processos produtivos é vista pela UNESCO como um dos fatores geradores da crise, assim como a perda estimada em 20% de recursos provenientes de aquíferos explorados acima da sua capacidade (Jacobi et al, 2015). Segundo o estudo da ANA 2017, a demanda por uso de água no Brasil é crescente, com aumento estimado de aproximadamente 80% no total retirado de água nas últimas duas décadas.…”

The water crisis and its implications in Brazilian agribusiness: A bibliographic review

et al. 2020

View full text Add to dashboard Cite

Water scarcity has become one of the main global problems, since of all the water of the terrestrial surface, only 2.5% represents fresh water, and of this, only 0.3% corresponds to the water of the rivers and lakes that are available to supply the demand for food production and other uses. The present work consisted in surveying the scenario related to the global water crisis and presenting evidence that even Brazil being abundant in the amount of water available, tends to face serious problems because of its scarcity, affecting two of the main economic pillars, agribusiness and industry. It was observed that the main negative effects on water resources occur due to urban occupation and agricultural practices in a disorderly way, causing destruction of natural resources through the discharge of domestic sewage, industrial effluents and agrochemicals. In general, the lack of control of the use of the water directed to the productive processes is one of the major generators of the water shortage, since 69% of the water derived from rivers, lakes and aquifers underground is turned to irrigated agriculture, using 70 times more water than for domestic purposes. Thus, it is necessary to adopt policies aimed at the conservation and efficient use of water resources, to value water as a social, social and environmental good, since their scarcity can generate instability in economic sectors such as agriculture, generating production insecurity in industry, as well as affecting the supply of drinking water, basic sanitation and public health.

“…Despite this abundance, water is irregularly distributed in the country. This is in part due to climatic variations throughout the year, modifying the flow regime of bodies of water which occurs in the Northeast region and suffers from a chronic situation of water shortages (Marengo, Alves, Beserra, & Lacerda, ; Rebouças, ), and in regions with greater economic and productive dynamism, such as the metropolitan regions, which face water‐use conflicts, both quantitative and qualitative, including water supply (Jacobi, Cibim, & Souza, ).…”

In order to assist with the management of water resources, this study aimed to calibrate the water quality model “Ottocoded Critical Basins Analysis” (ABaCO) in a section of the Lambari River, located in the city of Poços de Caldas, Minas Gerais, Brazil, and it is considered qualitatively critical by the “National Water Agency” (ANA). The calibration results, obtained automatically by the Microsoft Excel® tool Solver, showed good adjustments between the simulated and observed concentrations for the following parameters: total nitrogen, organic phosphorus, inorganic phosphorus, and total phosphorus, considering a visual interpretation of the graphics. The other calibrated parameters (BOD, DO, organic nitrogen, ammoniacal nitrogen, and nitrate) obtained satisfactory adjustments. When evaluating the results by coefficient of determination, it was observed that all parameters showed negative values to one or more field campaigns. However, the calibrated values of the parameters can be incorporated into the model to obtain a first view of the river's qualitative situation, aiming to plan, control, and protect water resources to assist in decision‐making and to favor performance of intervention analyses of environmental control measures. Practitioner points Calibration of water quality model in a section of a river located in Brazil considered qualitatively critical; The calibration occurred automatically and manually, when it was necessary, in an Excel® spreadsheet, generated from the water quality model; The automation process was performed by the Excel® Solver tool through the objective function; Through visual interpretation, it was noticed that the calibrated parameters were well adjusted to the data observed in the field; Sensitivity analysis showed that the studied parameters did not show significant differences in relation to the values calibrated for parameters.
