    Development and Application of a Methodology for the Identification of Potential Groundwater Recharge Zones: A Case Study in the Virvini Micro-Basin, Tiraque, Bolivia

    Groundwater plays a vital role in human consumption and irrigation in many parts of Bolivia; yet, the absence of policies to regulate its extraction and protect groundwater recharge areas has led to a decline in water tables and threatened food security. Some municipal initiatives have been implemented to develop regulations, but the lack of reliable hydrogeological data (such as aquifer geometry, groundwater level data, location of potential groundwater recharge zones, and flow dynamics) hinders their effective implementation. The case study presented herein focuses on a municipal policy in Tiraque, Bolivia, aimed at protecting groundwater recharge zones, in addition to the need for a reliable methodology for their technical identification. The EARLI approach (an acronym for “Enhanced Algorithm for Recharge based on the Rainfall and Land cover Inclusion”) is suggested as a participatory-simplified multi-criteria decision method to address the absence of hydrogeological data. This approach was adjusted to the basin’s specific conditions, including local vegetation communities and their influence on infiltration, and was applied as a pilot study in the Virvini micro-basin. The EARLI model emphasizes the spatial distribution of rainfall as an input indicator for potential recharge in addition to the biophysical characteristics of the catchment area. The methodology successfully mapped the degree of groundwater recharge potential and was validated by traditional hydrogeological models, field infiltration measurements, and the local community’s application of the tool. Therefore, the results of this study provide the necessary technical bases for groundwater-integrated management in Tiraque.

    Framing Water Policies: A Transdisciplinary Study of Collaborative Governance; the Katari River Basin (Bolivia)
    (Universidad Católica Boliviana "San Pablo". VLIR-UOS., 2022-11-18) Agramont Akiyama, Afnan; Peres-Cajías, Guadalupe; Villafuerte Philippsborn, Leonardo; Van Cauwenbergh, Nora; Craps, Marc; Van Griensven, Ann
    Collaborative water governance deals with diverse actors under participatory systems of decision making. This form of water governance involves stakeholders with fundamentally different values and premises about water resources, as well as different understandings of the problem and how to approach it. Thus, one of the major challenges of collaborative water governance relies on the diversity of frames carried by stakeholders involved and the shift from hierarchical decision-making to a more collaborative and participative process. The fragmentation of frames can represent an obstacle, impede mutual understanding, and negatively influence decision making and policy outcomes. Based on participative observation, interviews, and document analysis, we explored the drivers behind the framing process in the multi-actor platform of the Katari River Basin, located in Bolivia. The results highlight a participatory process design favoring the fragmentation of frames and a unidirectional decision-making process, where public authority, scientific–technical expertise, and the local community’s knowledge are insulated, and communication among actors is asymmetrical. At the same time, this research reveals the influence of the political context in the framing process.

    Integrating spatial and social characteristics in the DPSIR framework for the sustainable management of river basins: case study of the Katari River Basin, Bolivia
    (Universidad Católica Boliviana "San Pablo". VLIR-UOS., 2021-10-25) Agramont, Afnan; Van Cauwenbergh, Nora; van Griesven, Ann; Craps, Marc
    The drivers–pressures–state–impact–responses (DPSIR) framework has been used widely to support environmental policy developments. However, we argue that DPSIR tends to oversimplify the complexity behind socio-ecological systems. Based on the Katari River Basin in Bolivia, we explore how the incorporation of spatial and social considerations may enhance DPSIR applications. The results reveal a spatial mismatch between driving forces/pressures and policy responses, and severe impacts on the vulnerable communities. Moreover, we also show that local levels tend to be neglected. The study concludes that integrating spatial and social characteristics in the DPSIR may result in valuable implications for river basin management practitioners.
