“…In addition to these, according to FAO guidelines, other sectors, not traditionally categorized as Services, were included, such as livestock, in order to homogenize efficiency values in the study area. In this way, the WUE for services was not significantly changed and WUE for agriculture showed a relatively similar value to that found in other studies (FAO, 2018;Montoya and Finamore, 2020). In terms of water management, this aggregation is acceptable.…”

“…Therefore, the WUE (US $/m 3 ) indicates the monetary value generated by the volume of water used. The higher the value of this indicator, the greater the efficiency in the use of water of the sector or region (FAO, 2018;Montoya and Finamore, 2020). The WUE Total consider the sum of WUE of three sectors-Agriculture (A), Industry-MIMEC 2 (M), and Services (S)-weighted by the proportion of water used (P) by each sector, according to the following equation:…”

“…In the same manner, the WUE can indicate the number of employments generated per volume of water used (Employment /m 3 ) (Montoya and Finamore, 2020). The WUE values can vary widely depending on the predominant economic activity in the region studied.…”

Integration of a Network-Based and an Economy-Wide Water Model to Support Decision Making on Water Resources Planning and Management in Northeastern Brazil

et al. 2021

Allocation of Water Resources at the basin level is a critical issue for economic growth as well as for environmental sustainability. This study integrates network-based optimization with an Input-Output model, made available through a Spatial Decision Support System (HEAL), to support design and evaluation of water allocation policies. The innovative platform was applied to a case study using four-interlinked hydrographic basins in Northeastern of Brazil. The integrated modeling was able to measure broader socioeconomic impacts of decisions on reservoir volumes and water allocations at basin level, through indicators in a sectoral and regional scale, including ones associated with Sustainable Development Goals, such as the Water Use Efficiency (WUE) indicator. Results of the trade-offs between two scenarios, representative of the limits of performance of regulatory water instruments, were generated using the integrated modeling. They were compared with the Reference scenario for the base year (2011) and show that the economic sector most negatively affected by the regulatory instrument use is the industrial sector. Furthermore, the sugar and ethanol industry, main water users in the industrial sector (93.1% of the sector's water use) and less efficient (WUE 1.47 US$/m3 vs. 30.70 US$/m3 average of the sector) in the base year, maintain their percentage share of water use in the sector and even slightly expand it (93.2%), with slight efficiency gains (+2.3%). On the other hand, non-water-intensive industries, have their shares reduced (from 6.9 to 6.8%) and lose efficiency (−9.5%). Results of the same trade-offs by region showed that the largest proportional economic losses occur in the drier areas, damaging the economy, especially in the most industrialized municipalities with the highest GDPs. Integrated economic modeling can expand aspects involved in water security issues, assisting management by introducing socioeconomic impact measures, in a broader scale, associated with allocation decisions. Hydrological allocation criteria cannot distinguish between user efficiency and which economic sectors are using how much water. This results in economic and social losses. In water-scarce regions and with growing transfer needs, such as in the basins studied, adequate incentives, through management instruments designed based on economic theory, are essential to promote sustainable development.

“…Os incentivos governamentais adotados pela política brasileira para a expansão da agropecuária nas últimas décadas, sobretudo na região amazônica, impactam diretamente os recursos hídricos. Segundo Montoya et al (2019), o setor agropecuário absorve 77,46% do consumo total da água no país e apresenta a menor eficiência hídrica (R$10,91/m³) dentre as demais atividades econômicas.…”

Section: Resultado E Discussãounclassified

“…As atividades agropecuárias frequentemente são associadas à falta de água, seja pelo desperdício em função de uma inadequada gestão dos recursos hídricos, pela agressão ao meio ambiente, seja por simplesmente existir falta de clareza sobre o volume de água utilizado e o volume de água consumido no sistema econômico (MONTOYA et al, 2019). Porém, pelo fato do agronegócio possuir papel fundamental na economia brasileira, pois gera emprego e renda, apresenta papel ativo no saldo positivo da balança comercial nacional e destaca o país no comércio internacional (GOMES, 2019), muitas vezes a questão econômica supera as diretrizes para mitigar os impactos ambientais provindos dessas.…”

A bacia do rio Ribeirão Cacau, localizada no município de Alvorada D’Oeste em Rondônia, é indispensável para o desenvolvimento de diversas atividades econômicas locais, tais como a cafeicultura. Efetivar uma gestão integrada dos recursos hídricos nesta região ainda é um grande desafio, principalmente em decorrência do avanço das atividades agropecuárias. Desta maneira, a presente pesquisa buscou realizar uma análise do gerenciamento dos recursos hídricos na bacia supracitada sob o viés da participação da sociedade civil e do acesso à informação. Para tal, fundamentou-se em pesquisa bibliográfica e documental de forma a identificar práticas sustentáveis e aplicáveis em bacias hidrográficas em nível estadual para gerar contribuição para um melhor gerenciamento da bacia de estudo. Como resultado, pode-se identificar crescimento da demanda de outorga na bacia e ações de educação ambiental de incentivo a produção sustentável implantadas por iniciativas públicas e privadas que visam uma produção econômica voltada à sustentabilidade. Como contribuição e produto do mestrado ProfÁgua, foi formulada uma cartilha de sensibilização socioambiental para a produção da cafeicultura local e conhecimento da legislação hídrica. De outro modo, pode-se inferir que há necessidade de se manter investimentos em atividades e programas de educação ambiental, para que haja sensibilização dos cidadãos quanto à importância do seu papel no gerenciamento dos recursos hídricos.
