Both Ecosystem-based Adaptation (EbA) and Payment for Ecosystem Services (PES) have a wide range of strategies that include different economic instruments for nature conservation. Although the generation and maintenance of payment for hydrologic ecosystem services (Water-PES) is expanding in Brazil, there are difficulties in the implementation of projects. Due to the complexity and non-linearity of the hydrological processes, also affecting both EbA and Water-PES goals, monitoring qualiquantitative aspects of streams have been here addressed as a useful management tool. This study presents the Hydrological Monitoring Plan (HMP) of the Water Producer/PCJ project, operating between 2009-2014, in order to: 1) evaluate the impact of project actions under water quali-quantitative aspects; and 2) promote the incorporation of HMP's elements in water resources management. HMP of the Water Producer/PCJ project has been implemented following the conditions for efficiency (baseline, long-term scale compatible with the actions of the project, in the experimental and reference watersheds). In addition, HMP is being implemented from upstream to downstream in catchments with areas ranging from 17 to 130 km 2 . This proposal favors the quantification and valuation of hydrologic services that could be assessed by ecohydrologic monitoring and modeling. Thus, we look forward to the consolidation of the Brazilian information system of water resources, the reduction of modeling uncertainties and integrated assessment of the consequences of landuse/land-cover change that strongly impact goals of EbA and Water-PES initiatives.

“…For some authors, the absence of responses from formal participatory institutions to the water crisis can be explained by two factors: the lack of participation, transparency, and accountability -the principles of good governance -in the water governance system, as well as the lack of environmental justice (Jacobi et al, 2015;Fracalanza and Freire, 2015). Others have suggested the absence of strategic planning and the use of scientific information to support decision-making processes (Cortez et al, 2015), alongside a suite of more general assertions around population pressure and water wastage (Braga and Kelman, 2016;Otto et al, 2015;Tundisi and Tundisi, 2015). However, this and other literature has presented no discussion of the historical and structural factors shaping governance practices, which, in this case, allowed the São Paulo state governor as well as the state agencies and SABESP to control responses to the 2013-15 water crisis.…”

Governance and water security: The role of the water institutional framework in the 2013–15 water crisis in São Paulo, Brazil

2019

Between 2013 and 2015, São Paulo experienced a major drought. With drinking water reservoirs reduced to 5% of their capacity, the water supply company, SABESP, implemented measures to reduce household water consumption, while the Government of São Paulo State overruled watershed committees to prioritize the supply of water to SABESP. While attention centered on freak meteorological conditions, the management of water resources and water services also played a role; in particular the conversion of SABESP from a state company to a mixed capital company in which the State Government held a majority stake. As the crisis abated, the State Government announced measures to increase 'water security', comprising water diversion infrastructure to increase supply alongside governance reforms to improve state-led responses. This paper examines the relationship between water security and water governance in the context of the São Paulo water crisis. Most literature that analyses the governance dimensions of water security focuses on the principles of "good governance", including decentralization, transparency, and participation, which not only neglects that these can function instrumentally, but also risks ignoring the structure and scaling of the water institutional landscape within which governance takes place. We thus demonstrate how processes and structures that are broadly characteristic of "good governance" both exacerbated the effects of the drought and constrained responses to it. We make two related arguments. First, the mutually-beneficial commercial relationship between the state government and SABESP was fundamental in shaping these dynamics. Second, the drought experience, shaped by these dynamics, has legitimized a shift back towards a centralized, top-down and supply-led approach to water. This is discursively framed as envisaging future 'water security', yet serves to enhance SABESP's revenue streams, and consequently State Government finances. We thus suggest that the conventional view that good governance is conducive to water security needs to be reevaluated.

“…In addition, slope, topography, soil development and soil depth are also terrestrial characteristics of the watersheds which impact hydrologic services, as we have shown in The land-use/land-cover (LULC) changes of microcatchments contributing to public drinking supply are crucial for the production of water in adequate quantities and quality conditions (Whately & Cunha, 2007). Also, these changes lead to risks of potential water crisis with impacts on vulnerable ecosystems and people (Tundisi & Tundisi, 2015;. Comparing LULC in years 2003 and 2010, regarding soil uses, Figure 3.2 shows that the anthropic use is higher in Cancã catchment (66%) than in Moinho (around 50%) and…”

“…Paulo and Rio de Janeiro, the Tiete waterway was disabled during the Brazilian rainy season in 2014, resulting in the loss of 5,000 jobs and millions of tonnes of un-transported products (Tundisi & Tundisi, 2015), which shows that the multiple uses of water were affected by this severe drought. On the other hand, water withdrawals from reservoirs with very low levels (Coutinho et al, 2015) also pose problems related to water quality, with the settled sediments, metals, microorganisms and macronutrient over-enrichment, mainly phosphorous (Carpenter, 2005), which increase the water treatment costs.…”

“…However, land-use changes such as urbanization, industrial development, deforestation and intensive agriculture with rapid population growth and climate change threaten the supply of safe drinking water and ecological integrity. These changes lead to risks of potential water crisis with impacts on vulnerable ecosystems and people (Tundisi & Tundisi, 2015;.…”
