Quais fatores-chave podem promover a efetividade das alocações negociadas de água e seus acordos?

Autoria SCIMAGO INSTITUTIONS RANKINGS

Acordos pelo uso da água são estabelecidos para evitar, minimizar ou resolver conflitos relacionados a estes recursos. As negociações materializam os acordos, tornando-se importante analisar a efetividade tanto das negociações como dos acordos. Este artigo considera fatores-chave que colaboram para alcançar a efetividade das negociações e seus acordos em arenas de recursos hídricos, como o processo de alocação negociada de água que tem sido aplicado em reservatórios críticos no Brasil. Foram analisados dois sistemas hídricos na Bacia Hidrográfica do Rio Paraíba. Os resultados indicam que sistemas hídricos com maior relevância para o estado negociador e a presença das partes interessadas nas negociações tendem a resultar em acordos mais efetivos. Apesar das alocações negociadas serem uma ferramenta muito importante para o planejamento participativo em nível local, fragilidades institucionais podem enfraquecer o processo e fazer com que eles não cumpram os compromissos estabelecidos.

	Key factor	Meaning	Source
1	Rivers of high value to the negotiating state	Rivers with strategic locations that serve multiple uses are factors contributing to the success of the negotiation.	Brochmann & Hensel (2011)
2	Real problem and not future one	When it is a real problem, stakeholders are motivated to seek a solution	Brochmann & Hensel (2011)
3	Highly contentious issues (water quantity, navigation, water quality)	When contentious issues are debated during negotiations, they lead to greater effectiveness in those negotiations.	Tir & Stinnett (2011)
4	Opponents with closer relationships	The opponents engage in dialogue, collaborate, and seek common resolutions to reduce conflicts.	Brochmann & Hensel (2011) and Zareie et al. (2021)
5	Consideration of local needs	Negotiations must take into account the system's local potential and vulnerabilities to be successful.	Giordano et al. (2013)
6	Stakeholders participation	The actors involved in the conflicts must participate in the negotiations for them to be successful.	Giordano et al. (2013), Laurenceau et al. (2020), and Offutt (2022)
7	Inclusion of non-state actors in negotiation arenas	Actors outside state institutions, such as users and civil society, must participate in the negotiations, as they are impacted by or influence the conflict.	Haefner (2016) and Denoon et al. (2020)
8	Power distribution among local actors	When power is distributed more evenly, debates tend to seek consensus and mutual benefits, without one group dominating the others.	Mutahara et al. (2019)

	Key factor	Meaning	Source
1	Clear allocation structure	Specifying how the allocation should occur makes the agreement more effective.	Giordano & Wolf (2003) and Petersen-Perlman et al. (2017)
2	Flexible allocation criteria	Agreements should consider the possibility of adjustments.	Giordano & Wolf (2003) and Horbulyk (2017)
3	Equitable distribution of benefits	There should be an equitable distribution of benefits, taking into account the current legislation and system characteristics.	Giordano & Wolf (2003)
4	Effective monitoring	Data about the system must constantly be updated to enable effective monitoring.	Petersen- Perlman et al. (2017) and Grünwald et al. (2020)
5	Consideration of local needs	Agreements should be developed based on the characteristics of the water system.	Giordano et al. (2013)
6	Conflict resolution mechanisms	The agreements that include conflict resolution mechanisms may be more effective.	Giordano & Wolf (2003) and Hussein et al. (2023)
7	Participation of river basin organizations	The river basin committee should be directly involved in developing agreements.	Mitchell & Zawahri (2015), Schmeier & Shubber (2018), and Chilima et al. (2021)
8	Exchange of information between actors	Information about the implementation of actions should be regularly disclosed and easily to be understood, as this facilitates informed decision-making and enables more effective agreements.	Mitchell & Zawahri (2015), Hasan et al. (2023), and Lu et al. (2023)
