“…Source: own elaboration from the questionnaires. Notes: 1 Petition was on 1986; 2 Latest statutes in 2015; 3 Although the first irrigation campaign with desalinated water was in 1979 with the arrival of the TST; 4 This surface increases until 3515 ha (taking into account the surface currently occupied by the industrial park); 5 This surface is reduced to 32,000 in a dry period; 6 Part of this surface (12,620 ha) corresponds to traditional irrigation (unregulated); 7 Some farms up to 200-300 ha; 8 Some farms up to 400 ha; 9 Some farms up to 40-50 ha; 10 Professional farmer: 20 ha, with 7-8 large fruit and vegetable companies (25-30 ha each one); 11 Some farms up to 50-100 ha; 12 One horticultural company uses 800 ha and a fruit company, about 300 ha; 13 Some horticultural companies up to 150 ha; 14 Vegetables include lettuce, broccoli, artichoke, cauliflower, tomatoes, celery, potato, onion, and pepper; while fruits include citrus, melon, watermelon, grape, and mango.…”

“…Water scarcity is considered one of the most important challenges of our time, constituting an increasing problem in many parts of the world [3]. Agriculture is the sector most affected by water scarcity, as it accounts for 70% of global freshwater withdrawals and more than 90% of the consumption [4,5]. In this context, non-conventional water resources and more specifically, seawater desalination, is considered as an additional water resource to help overcome water scarcity [6,7].…”

Although desalination water cost and quality standards have been widely studied, less attention has been paid to understanding how desalination plant managers and irrigation communities interact to address water scarcity. This paper aims to approach these questions from experience in Alicante and Murcia (Spain). Two specific questionnaires have been applied to (1) three desalination plants managed by the Spanish public company ACUAMED, and (2) 11 irrigation communities who use desalinated seawater. Discursive analysis has been applied in order to deepen understanding on the driving factors, benefits, and barriers of desalination use and management. Results highlighted how (1) irrigation communities consider desalination as a complementary water source to be combined with conventional water resources, (2) both ACUAMED and irrigation communities highlighted two main advantages of desalination: the security/guarantee of supply and water quality parameters, and (3) managers and irrigators disagree on the desalination model of seawater provision and management, since irrigators consider that the Central Union of the Tajo-Segura transfer irrigators (SCRATS) should have a leading role. In addition, the main driving factors and barriers useful for policy makers when closing the gap of desalination have been identified: water price and energy consumption; lack of water storage capacity and regulation; environmental impacts.

“…Diversas ações no mundo estão voltadas para a reutilização de água, com destaque para fins hidroagrícolas (Meng et al, 2016;Vanham et al, 2018). Através da Agenda 2030 para o Desenvolvimento Sustentável, as Nações Unidas também estão pressionando pela adoção mundial de tecnologias de reutilização, como uma ferramenta essencial para atingir seus Objetivos de Desenvolvimento Sustentável (ODS) (Ricart & Rico, 2019).…”

A escassez de água no semiárido pernambucano, associada à necessidade de produção agrícola contribuem para uso de efluentes domésticos tratados para fins hidroagrícolas. No entanto, para intensificação do reuso de água são necessárias ações de gestão participativa, principalmente aos jovens do meio rural, incentivando a permanência no campo. O estudo objetiva avaliar a viabilidade de cultivos agrícola com o reuso de efluente doméstico tratado, associado a práticas de conservação de água e solo, no semiárido. Desta forma, este estudo apresenta resultados de produção de milho, girassol e sorgo irrigado com esgoto doméstico tratado, com participação de agricultores rurais e jovens locais. O estudo foi desenvolvido na Estação de Tratamento de Efluentes (ETE) localizada no Distrito de Mutuca, Pesqueira-PE. O plantio do milho (Zea mays L.), realizado em 2016, e do girassol (Helianthus annuus L.), em 2017, foram realizados em duas parcelas experimentais, uma sem e outra com lodo de esgoto (LE), e o sorgo (Sorghum sudanense (Piper) Stapf) foi cultivado em 2019, com e sem cobertura morta (CM) (capim natural). O monitoramento agrometeorológico foi realizado de forma participativa com moradores e alunos de escola da comunidade local. Constatou-se que a altura das plantas, o diâmetro do caule e o número de folhas foram superiores nos tratamentos em que foram adicionados LE no girassol, e no diâmetro do colmo para o milho e sorgo. As aplicações de LE e CM promoveram incremento da umidade do solo. Através da gestão participativa, ações voltadas à intensificação do uso de efluentes domésticos e lodo de esgoto para fins hidroagrícolas devem ser incentivadas, promovendo a produção de alimentos e aumento de renda aos produtores agrícolas.

“…In this form, TWW can constitute a freshwater resource for agriculture (irrigation), industry (cooling purposes) and public services (drinking water) [11]. The extent of its usefulness is, however, limited by its quality and the regulations associated with reuse [12]. The EU recognise water as a resource which should be managed as a key element of the circular economy [13].…”

“…The EU recognise water as a resource which should be managed as a key element of the circular economy [13]. Indeed, literature points to the direct reuse of TWW becoming a more common trend in the future, both internationally [14] and in the EU [13], if appropriate regulations can be devised [15] and the societal "yuck" factor can be overcome [12]. These reports, however, generally neglect to include the occurrence of de facto reuse as a component of water reuse initiatives.…”

Following the Water: Characterising de facto Wastewater Reuse in Agriculture in the Netherlands

2019

View full text Add to dashboard Cite

De facto (or indirect) wastewater reuse is the practice of extracting from surface water bodies which are impacted by treated wastewater (TWW) for anthropogenic use. The extent to which surface water bodies in the Netherlands are impacted by TWW is poorly understood, and the distribution of de facto reuse even more so. This study addresses these knowledge gaps, with a focus on reuse for agricultural irrigation. This is achieved via a novel application of the Water Framework Directive (WFD) Explorer water quality model, allowing for the distribution of different flow components-namely TWW and flow from transboundary rivers-to be discerned for the national surface water network. When paired with data on surface water extractions for irrigation, this identifies notable areas of de facto reuse. Results show that during dry conditions, TWW is a significant flow component in many surface water bodies, particularly in smaller streams located close to WWTPs. De facto reuse is indicated as widespread, with several key areas identified in which extractions are from impacted surface water bodies. This study represents a first attempt to directly link TWW emissions to agricultural irrigation, highlighting a mechanism by which wastewater-associated contaminants can propagate through the hydrological system.
