“…Water security implies that stakeholders, both humans and ecosystems, have sufficient access to water in the appropriate quality at the right spatial-temporal scale. Therefore, assessments and monitoring of water quantity and quality must be conducted regularly encompassing all related aspects, such as impacts on biodiversity and human livelihoods (Veilleux & Anderson, 2016). Science-policy interactions for facilitating transboundary water governance were found to be most effective when all stakeholders recognize science as a crucial input to policy-making process, the knowledge on water governance is co-produced in an trans-disciplinary manner, and informal networks of scientists, policy makers, and civil society are facilitated (Armitage et al, 2015).…”

This paper proposes that transboundary water governance needs to become an essential input to sustainable governance of protected natural reserves. The paper reviews the challenges and opportunities for such governance mechanisms, and identifies the factors behind successful practices. Successful transboundary governance of water and nature requires the reduction of associated transaction costs. Firstly, water diplomacy through joint research, data collection and monitoring, capacity building, dialogues for consensus building, promoting responsible leadership and providing advisory support can help in overcoming mistrust between stakeholders and create opportunities for cooperation. Secondly, power asymmetries may hinder transboundary water governance, therefore, there is a need to involve multi-scale links across stakeholders to counterbalance local power asymmetries and engage all stakeholders in consultations and negotiations. Thirdly, transboundary water governance is critically dependent on accurate and transparent data and analysis tools for informing policy decisions. Science-policy interactions for facilitating transboundary water governance were found to be most effective when the knowledge on joint water and nature governance is coproduced in a trans-disciplinary manner, in collaboration with wide-ranging informal networks of scientists, policy makers, and civil society. Finally, transboundary water governance organizations can serve as platforms for facilitating water diplomacy, building trust and cooperation, especially when they are granted the ability to enter into binding cooperative agreements regardless of external political pressures.

“…Climate change and resulted phenomena like increases in frequency and intensity of floods, droughts and salinity intrusion have significant effects on agriculture and food production (Deschênes and Greenstone, 2007; Parry et al , 2007; Chavas et al , 2009; Nelson et al , 2009). With more extreme weather events, major river basins worldwide such as The Nile, Mekong and Amazon demonstrate similar water security challenges that affect people's livelihoods and reduce agricultural productivity (Van Dam, 2003, Hamouda et al , 2009; Szabo et al , 2016; Veilleux and Anderson, 2016). This is particularly the case of the Mekong River basin, where the economy depends heavily on agriculture (Nelson et al , 2009; Le Dang et al , 2014; Vu et al , 2018).…”

“…The number of dams being constructed around the world is increasing, with numerous and extensive ecological and social consequences (Veilleux & Anderson, 2016; Winemiller et al, 2016; Zarfl, Lumsdon, Berlekamp, Tydecks, & Tockner, 2015). Dams reduce hydrologic connectivity—the water‐mediated transport of matter, energy, and/or organisms across elements of the hydrologic cycle (Pringle, 2003)—and have been identified as one of the most threatening factors to freshwater biodiversity (Vorosmarty et al, 2010).…”

Hydropower development is accelerating in the tropics, especially construction of small dams. Small dams are often classified as those lower than 15 m in height or with reservoir capacity less than 3 × 10 6 m 3. Small dams frequently operate with water diversions from the main river channel, thereby affecting river connectivity through the creation of a dewatered reach. However, the extent and impact of dewatered reaches have been overlooked in most analyses of river fragmentation and dams to date. In Costa Rica, small dam development increased during the 1990s, ahead of current trends in other tropical regions. This study examined the effects of dams and their dewatered reaches on river connectivity at a national scale in Costa Rica. We adapted the Dendritic Connectivity Index and applied it to the four basins where over 80% of hydropower development has occurred. Our results showed that in two basins, the Sarapiqui and San Carlos, dewatered reaches contributed most to river fragmentation. In the Tarcoles and Reventazon basins, dams and dewatered reaches had similar effects on river fragmetnation. These different patterns can be explained by the spatial arrangement of dams in the individual river networks. We also found that dewatered reaches extended the elevation range of rivers affected by hydropower activity; this expansion was most significant in cases with interbasin water transfers. We discuss the implications of our findings on connectivity losses from dams for fishes whose range overlaps with hydropower activity. Our study may provide insights for other tropical countries with ongoing and future small dam development.
