1. Introduction
Water is one of the most essential natural resources for sustaining life, human well-being, and ecosystem balance. Both its availability and quality are determining factors for food security, public health, economic productivity and the resilience of natural systems to climate change [
1,
2]. In this framework, water sources play a strategic role in regulating the hydrological cycle, stimulating groundwater infiltration and storage, and ensuring a sustainable flow for domestic, agricultural, and ecological needs [
3,
4].
The Totorani micro-basin, located in the district of Puno, represents an ecosystem of great socio-environmental importance, providing approximately 10% of the water supply to the city of Puno, which has more than 145,000 inhabitants [
5]. The source that supplies the northern part of the city of Puno is groundwater from Totorani, which benefits more than 21,000 residents and supports long-standing agricultural and soil conservation practices. It also hosts wetlands and high-altitude springs that perform essential ecological functions in water regulation and biodiversity preservation [
6,
7,
8]. Increasing anthropogenic pressure, such as uncontrolled urban growth, agricultural expansion, and soil degradation, along with climatic variations, are negatively impacting the natural recharge capacity of the basin [
9,
10].
In this research, the term
bofedales refers to high-altitude Andean wetland grasslands, which represent unique ecosystems located mainly above 3000 m [
11,
12].
Bofedales act as natural sponges, retaining water from rainfall and snowmelt and gradually releasing it during dry spells, which play a crucial role in local hydrology [
13,
14]. These wetlands are distinguished by their hydromorphic vegetation, such as Distichia and streamside grasses, and function as essential pastures for feeding camelids in winter, important carbon sinks, and vital water sources for local communities. More than 50% of the
bofedales are concentrated in southern Peru [
15,
16], and their preservation is essential due to threats posed by climate change, overgrazing, and illicit peat moss extraction.
The study of water recharge areas in the Andean regions poses a significant challenge due to the harsh geographical and climatic conditions typical of these areas, where water resources are limited and vulnerable [
12,
14].
The identification and mapping of recharge areas using scientific approaches and stakeholder participation enable an understanding of hydrological processes, the determination of priorities for critical conservation areas, and sustainable land use planning [
2,
16]. In recent years, multicriteria analysis models integrated with Geographic Information Systems (GIS) have proven highly effective for delineating recharge areas [
3,
17]. For example, a GIS-based MCDA approach using AHP successfully identified water recharge areas using a Management Aquifer Recharge (MAR) system in semi-arid conditions in southern Kazakhstan, supported by hydrogeological field data and expert assessment of key criteria, such as aquifer depth and drainage density [
18]. In the Ponnaniyaru watershed in India, a GIS, together with AHP and MIF (Multi-Influence Factor) techniques, effectively classified areas with groundwater potential, which was validated by an ROC curve analysis [
19]. The multicriteria comparative methods used in the Willochra catchment (Australia) confirmed that integrating GIS with AHP and other decision rules yielded consistent classifications of recharge potential, and that a substantial portion of the basin was identified as having a high recharge potential when validated with the well data [
20]. These tools allow for the evaluation of variables, such as vegetation cover, slope, soil type, geology, and land use, as well as other thematic maps, providing highly reliable results even in situations where hydrometeorological information is limited [
21,
22]. However, several studies agree that purely technical approaches, based on expert-driven engineering designs, hydrological models, and top-down decision-making, without significant input from local stakeholders, are insufficient to achieve sustainable outcomes in watersheds; they need to be combined with social participation, the integration of local knowledge and the involvement of relevant community and institutional actors [
23,
24,
25,
26,
27,
28].
The aforementioned studies were conducted in semi-arid or monsoon-fed regions, which contrasts with the focus of this current research on the challenging Andean environment of the Totorani micro-basin. The Andean region faces distinctive hydrological, climatic, and socio-environmental challenges, driven by the extreme altitude, pronounced seasonal variation, and the vital role of wetlands and springs in regulating water.
The Totorani basin faces specific risks, including rapid urban growth, agricultural demands, and climatic fluctuations, which directly affect the water recharge mechanisms. Addressing these obstacles requires not only technical solutions but also the integration of local knowledge and community involvement to ensure sustainable management.
By combining an advanced spatial analysis with community feedback and traditional knowledge, the study produces findings that are both scientifically rigorous and socially pertinent. This methodology is specifically tailored to the complex characteristics of the Andean setting, carefully considering both the physical and social aspects of water recharge management and providing a pragmatic framework for sustainable water governance in locations such as Totorani, where community involvement is crucial.
In this context, participatory analysis is presented as a fundamental tool for strengthening water governance by involving the local actors in knowledge generation and land management decision-making. In the Totorani micro-basin, traditional knowledge related to wetland management, springs, and ancestral conservation techniques is intertwined with current science, thus enriching water planning and monitoring processes [
29,
30,
31].
From a legal perspective, Peru’s legal framework, specifically Water Resources Act No. 29338 [
32], acknowledges the importance of an integrated and participatory approach to water management as a guiding policy for sustainability. Consequently, the identification and protection of water recharge areas not only respond to technical requirements but also align with a national policy focused on water security and the achievement of Sustainable Development Goal 6 (clean water and sanitation) [
33,
34]. Therefore, this analysis suggests a combined approach integrating local community participation with geospatial tools (multicriteria analysis and GIS). This process aims to combine science, regulations, and ancestral knowledge to generate accurate information on water recharge areas in the Totorani micro-basin. The results will serve as a basis for designing conservation strategies, territorial planning, and promoting water resilience in high-altitude Andean ecosystems in the face of climate change.
This study presents an innovative framework that combines the Analytic Hierarchy Process (AHP), Geographic Information Systems (GIS), and participatory stakeholder involvement to tackle the intricate challenges of Andean and mountainous watersheds. By integrating quantitative spatial modeling with local knowledge, the methodology strikes a harmonious balance between scientific precision and community pertinence, notably enhancing the precision of recharge zone delineation. Specifically tailored to address the region’s distinct hurdles, such as extreme altitude, seasonal variations, and the crucial significance of wetlands and springs, the approach actively engages local stakeholders, linking scientific principles with traditional methods. Through its comprehensive, multicriteria, and participatory approach, the methodology not only enhances understanding of recharge dynamics but also establishes a transferable model for comparable mountainous areas. Above all, the research findings will directly influence policy-making and conservation tactics, setting a novel standard for participatory environmental governance in high-altitude basins.
2. Materials and Methods
2.1. Research Location
The study was conducted in the Totorani micro-basin, which has an area of 61.39 km
2 and a perimeter of 42.042 km. It is located in the Puno District, in the high Andean region of Peru, at an average altitude of 4054.8 m above sea level (
Figure 1). This micro-basin is of great importance to the city of Puno, supplying approximately 10% of the water used for human consumption and local agricultural activities. The area is characterized by a cold semi-arid climate, with an average annual temperature of 7 °C, marked seasonality in rainfall from November to April, and a hydrological pattern strongly influenced by topographical and orographic factors. The predominant land cover includes high Andean grasslands, wetlands, and agricultural areas, ecosystems that are fundamental to water regulation.
2.2. Methodological Approach
The study employs a mixed-methods approach, which combines spatial analysis techniques with a participatory approach. This integrated methodology allows for the collection of objective scientific data using Geographic Information System (GIS) tools and multicriteria models, while also incorporating local knowledge and the perspectives of stakeholders involved in water management [
24,
25]. The combination of methods addresses the need to consider water replenishment as both a biophysical phenomenon and a social process [
29].
2.3. Collection of Information
2.3.1. Spatial and Biophysical Data
To obtain the spatial and biophysical information, geological and geomorphological maps, slope maps, and drainage maps from the National Geographic Institute (IGN) and the National Water Authority (ANA) were used.
The terrain slope was obtained from Land Viewer’s Digital Elevation Model (DEM) with a 5 m resolution, which was also used to calculate the micro-basin parameters. The small size of the basin and the need to record the complex variations in slope and terrain in the difficult conditions of the high Andes required such a high spatial resolution. The slope was calculated using the standard QGIS algorithm, which measures the greatest change in elevation between each cell and its neighbors. Before the analysis, the depressions in the DEM were refilled to remove artificial sinks and maintain hydrological consistency.
The geological map used to characterize the lithological units was provided by the Geological, Mining and Metallurgical Institute (INGEMMET). The climate data (precipitation and temperature) were obtained from international databases, such as WorldClim v2.1 [
35]. The information on land use and land cover was provided by the Peruvian Ministry of the Environment (MINAM). These were corroborated at various points in the micro-basin.
2.3.2. Social and Participatory Data
Semi-structured interviews were conducted with different local stakeholders, including farmers and livestock breeders (30); community leaders (seven) from Japuchuro, Machallata, Micaela Bastidas, San Miguel de Antonani, Secsani, Totorani Grande, and Yayawani; teachers (four); and local authorities (nine) from various institutions—the Water Administration Authority (AAA), the Puno Municipal Sanitation Company (EMSAPUNO), the National Superintendence of Sanitation Services (SUNASS), the Paucarcolla District Municipality (MDP), and the Puno Provincial Municipality (MPP). Three interactive workshops were held to identify traditional practices for managing wetlands, springs, and grasslands, and to gather information on the threats to water resources. Matrices for setting priorities and collective mapping were used to identify the critical water recharge areas. The participants directly identified the strengths, weaknesses, opportunities, threats, and the institutional actors operating in the micro-basin. In addition, panels of paper with maps and diagrams were used to identify the critical areas in the territory visually. These activities were carried out between January and October 2023.
The interactive workshops were attended by 30 farming families and seven community leaders, representing the main stakeholders in the Totorani micro-basin. Even though the sample size was small, it was representative of the limited population who are directly involved in water resource management within the micro-basin. The sessions focused on improving understanding of integrated water resources management (IWRM) and conservation strategies.
2.4. Multicriteria Analysis
To delimit the water recharge areas, we applied the multicriteria hierarchical analysis technique [
36], which is widely recognized in water resource studies [
16,
17]. There were five key variables: vegetation cover, slope, soil type, geology, and land use. Each variable was weighted using pair-wise comparison matrices, validated by the consistency index (CI < 0.1).
The Analytical Hierarchy Process (AHP) was used to define the water recharge areas within the Totorani River micro-basin, accounting for the critical factors: vegetation cover, slope, soil type, geology, and land use. Stakeholder engagement was methodically integrated through collaborative workshops involving farmers, community leaders, educators, and local officials, who contributed their qualitative perspectives on the relative significance of each factor. These viewpoints were quantitatively amalgamated using pair-wise comparison matrices. While experts determined the final priorities, these assessments were openly communicated and authenticated through consensus and interactive dialogue with local expertise. This method ensured methodological precision and the meaningful integration of community viewpoints, culminating in a robust, contextually relevant model for holistic water resources management in the Totorani micro-watershed.
The five physical variables were selected for their established significance in controlling infiltration, runoff, and subsurface water flow, as corroborated by recent research by Abdullah, Idrak, Kabir and Bhuiyan [
3]; Raja and Mathew [
17]; and Dongare and Deota [
16]. These studies highlight the fundamental role of these factors in assessing the groundwater recharge potential, especially in mountain regions. The geology and soil type influence groundwater mobility and storage; the slope affects infiltration and runoff; and the vegetative cover regulates infiltration and soil retention. The incorporation of these variables into a multicriteria analysis is widely accepted in hydrological research, ensuring a reliable and reproducible method for mapping the recharge areas in the Totorani micro-basin.
The hierarchical pair-wise model was implemented using a 5 × 5 comparative matrix. The characteristics of the physical environment relevant to estimating the water recharge were analyzed using a pair-wise comparison. Subsequently, a normalization matrix for the water recharge was explicitly developed, and the resulting values are presented in
Table 1. The normalization matrix showed values of 0.46, 0.28, 0.16, 0.06, and 0.04 (
Table 2), reflecting the respective importance of each variable within the model. Subsequently, a paired comparison was carried out, with the results presented in
Table 3.
The relative ponderations of each variable were determined using pair-wise comparative matrices and validated using the consistency index (CI) and consistency ratio (CR) test scores, both of which were well below the recommended threshold (CI = 0.02, CR = 0.02), confirming the reliability and accuracy of the weighting process. In addition, the results of interactive workshops were fed through the model: the stakeholders provided feedback on the relevance of each variable, which influenced the final scoring scheme. Such participatory validation ensured that the model components were not only academically robust but also aligned with local knowledge and priorities.
The consistency analysis suggested by [
37] considers the calculation of
λmax, which is the principal eigenvalue calculated using the eigenvector technique, and
n is the number of criteria (factors) using Equations (1) and (2).
where
n represents the number of independent rows in the matrix,
A represents the pair-wise comparison matrix, and
v means the matrix eigenvector. (
Aν)
i is the
i-th element of the matrix–vector product (pair-wise matrix × eigenvector). (
nνi) is the
i-th element of the eigenvector multiplied by the number of criteria.
Therefore, pair comparison helps improve the evaluation of error consistency, so it is advisable to use the consistency ratio (Equation (3)).
where
RCI is the random consistency index.
Saaty [
36] recommended that the CR value be less than 10%; otherwise, the weights must be reevaluated to maintain consistency. The best solution would be an IC = 0. Therefore, consistent values correspond to CR < 1.
The calculation of the weighted sum vector and the prioritization vector for the physical environment parameters yielded the following values, 5.18, 5.13, 5.09, 5.03 and 5.02, with a total sum of 25.45 and an average of 5.09. Based on these results, a consistency index (CI) of 0.02 and a consistency ratio (CR) of 0.02 were calculated. Both values are significantly lower than the recommended threshold of 0.1, confirming that the model is consistent and that the weights assigned to each parameter are appropriate and consistent across the analysis (
Table 3).
The added values in
Table 3, called the ‘weighted sum vector’, come from the pair-wise comparison matrix for each attribute. This vector has a key role in determining the principal eigenvalue (
λmax). To calculate the
λmax, each element of the weighted sum vector is divided by the corresponding element of the recharge vector, and the averages are calculated. These calculations are essential for maintaining logical coherence in pair-wise comparisons and validating the reliability of the weights assigned to each parameter in a multicriteria analysis.
The determination and identification of water recharge zones were carried out according to the criteria detailed in
Table 4, which presents the weights assigned to the five physical environment variables. These variables were grouped into five main classes, each with its own respective rating level, which allowed for assessing the possibility of water recharge within the Totorani micro-basin.
2.5. Participatory Validation and Analysis
A participatory cross-validation method was used, in which the preliminary maps were shown to the workshop participants to elicit agreement and disagreement regarding their knowledge of the territory [
23]. The findings of the spatial analysis were compared with the field data and the impressions of local actors. The final zoning was improved and its social legitimacy was ensured through this process, a crucial element for comprehensive watershed management [
30,
31].
The research approach enabled analysis of the roles and perspectives of participants involved in water resource management in the Totorani micro-basin. This method was appropriate for understanding the complexity of social dynamics and the relationships related to water. The key actors were carefully identified and selected, including government entities, non-governmental organizations, local authorities, members of the local community, and other important participants.
Data collection was carried out using various techniques, including document review and focus groups. These methods provided qualitative data from the stakeholders regarding their perspectives and experiences in water management.
An analysis of the collected information was conducted by detecting patterns, themes, and trends in the stakeholder responses, which facilitated an understanding of the dynamics and challenges in water resource management. Active stakeholder participation in the research process was encouraged, including feedback sessions in which the preliminary results were discussed to gather their opinions and additional perspectives.
The identification of the main actors involved in the management and administration of water resources was carried out using the nominal group technique, a method for identifying the important actors or groups involved in a central action or problem [
38,
39,
40,
41,
42]. This technique can also be used to visualize the differences between the actors who may influence a situation or line of action, and those who may be affected by it [
43,
44].
Once the key actors were identified, they were characterized using the methodological tools of social analysis (collaboration/conflict, legitimacy, interests and power), and to identify the interactions and relationships among them, an analysis of social relations (ASR) was used.
The profiles of the actors were defined based on four factors: relationships of collaboration and/or conflict, legitimacy, interests, and power linked to water resources. To do this, the area was first defined, identifying the key actors involved in the conflict and water resource management. A mental map was then constructed with the actors involved and the strategic links for good management. The following matrices were then systematically developed: power, interests (gains and losses), legitimacy, collaboration, and conflicts [
38,
39,
40,
41,
42].
To examine the interactions and relationships among the key actors in the basin, a social network analysis was used to visualize the power relations and specific roles among the actors (authorities, organizations, associations, companies, regional authorities, among others), identifying information flows and bottlenecks [
45].
In this study, the categorization of “dominant” as proposed by authors Ashley and Carney [
46] and Dutta [
47] is not used, who characterized the actors in water resource management in a basin [
44]. Instead, our approach is based on four categories: “strong”, “respected”, “inactive” and “vulnerable”.
2.6. Ethics in Research
The study was conducted in compliance with the principles of participatory ethics, ensuring informed consent from the stakeholders involved and data confidentiality. Furthermore, efforts were made to ensure that the workshops were not only places for data collection, but also for feedback and strengthening the local capacities for water management.
2.7. Information Processing and Analysis
The layers were then combined in QGIS to create a map showing the likelihood that the areas were water recharge areas (
Figure 2). The qualitative data were analyzed using a content analysis, with emerging categories identified for water management practices, risk perceptions, and conservation strategies.
UCINET version 6 software was used to analyze the roles of stakeholders in planning, training, and financing activities. This tool facilitated the identification and visualization of key actors and their interactions in the basin. The qualitative data obtained from the interviews and workshops were systematically coded using UCINET to ensure methodological rigor of the analysis. The study received ethical approval, and all participants provided informed consent.
3. Results
3.1. Delimitation of Water Recharge Through Multicriteria Assessment
The application of multicriteria hierarchical analysis in the Geographic Information System (GIS) allowed for the zoning and classification of the Totorani micro-basin into four levels of susceptibility to water recharge (
Figure 3). Two main areas with significant water recharge potential can be distinguished in the micro-basin, both classified as high and very high.
The spatial examination of the Totorani micro-watershed indicates the prevalence of moderate groundwater recharge, covering 56.01% of the territory (34.38 km2). High recharge areas, which account for 39.91% (24.5 km2), are primarily located in the mid-section of the basin and play a vital role in water infiltration and storage. Very high recharge regions, accounting for 3.81% of the total surface area (2.34 km2), are concentrated in the high-altitude Andean wetlands, springs, and segments of the Totorani, Lluscamayo, Quelloccaca, Cachiña, and Llallahuane ravines. These areas encompass various population centers, such as Totorani, Ceccecani, Totorane Pata, Cachiña Grande, and Campanane, and are of significant importance for the conservation of water resources. Conversely, low recharge zones account for only 0.28% of the micro-watershed (0.17 km2), are primarily found on slopes exceeding 30°, and characterized by scant soils and limited infiltration capacity, and thus represent the smallest portion of the territory in terms of water accumulation and preservation.
3.2. Roles of Stakeholders Through Participatory Action
The participatory workshops largely confirmed the zoning produced by the spatial analysis. The local communities and authorities identified the Llallahuani wetlands and the Campanane springs as significant recharge areas, which coincided with the areas classified as “very high” in the model. They also pointed to areas impacted by overgrazing and urban expansion as critical areas with reduced infiltration capacity, in line with the areas classified as “low” and “very low.”
The combination of technical and participatory findings led to the identification of three water recharge areas for intervention:
Upper Zone (Llallahuani–Campanane sector): Includes bofedales and wetlands essential for water regulation.
Middle Zone (traditional terraces): Has the potential for restoration and promotion of sustainable agricultural practices.
Lower Zone (peri-urban area of Puno): Presents with high human pressure and a risk of spring loss.
The nominal identification of the actors involved in water resource management and administration has been established. So far, only a few state institutions with influence in this area have been identified. Furthermore, these actors must lead and collaborate in the management of the micro-basin along with private organizations.
Figure 4 identifies several institutions and organizations that play crucial roles in water resource management in the Totorani micro-basin. These include the Water Administration Authority (AAA), the Puno Municipal Sanitation Company (EMSAPUNO), the Paucarcolla District Municipality (MDP), the Puno Provincial Municipality (MPP), the National Superintendence of Sanitation Services (SUNASS), and the National University of the Altiplano (UNA). Civil society organizations comprise the communities located within the Totorani micro-basin, including Japuchuro, Machallata, Micaela Bastidas, San Miguel de Antonani, Secsani, Totorani Grande, and Yayawani.
In terms of stakeholder characterization, the AAA, EMSAPUNO, and SUNASS have been assigned to the “strong” category due to their predominant influence on decision-making and water resource management in the area. The MDP and MPP are in the “respected” category, meaning they play a significant role but have less influence compared to the strong institutions. Furthermore, all local communities are in the “inactive” category, indicating that their participation and influence in water resource management are currently limited. However, the UNA is considered “vulnerable”, implying that its position is less supported compared to the stronger institutions. The stakeholder characterization provides significant insight into the challenges and dynamics of water resource management in the Totorani micro-basin (
Table 5).
The perspective presented here assumes that the actors categorized as “strong,” including EMSAPUNO, AAA, and SUNASS, have the obligation to lead and coordinate actions related to water resources management and administration. The prominent role of these key actors is crucial to promoting effective actions in this area, including capacity building (
Figure 5), planning and implementation (
Figure 6), and financing activities (
Figure 7).
The participatory analysis reveals the uneven process of the capacity building dynamics of the Totorani micro-watershed. As shown in
Figure 5, the outflow density is 87.50%, indicating that the flow of information, technical support, and resources from dominant institutions to local actors is considerably greater than the inflow density of 24.31%, which reflects the response of local communities or organizations and their effective participation. This asymmetry reveals a still centralized governance structure, where the institutional leadership of EMSAPUNO, SUNASS, and AAA predominates in the planning and execution of actions, while community participation is limited and self-management is low.
The network diagrams shown in
Figure 5,
Figure 6 and
Figure 7 examine the interactions of actors in the Totorani basin. In these representations, the nodes represent the individual actors or institutions involved in water resource management, while the arrows depict the relationships or exchanges among the stakeholders (e.g., information, resources, or influence). The thickness of the arrows represents the intensity or frequency of these interactions, and the colors differentiate between types of relationships (e.g., planning, training, and financing). The outgoing density indicates the proportion of connections emanating from a specific actor, revealing their role in the dissemination of resources or information. In contrast, the incoming density measures the proportion of connections received, indicating an actor’s participation or dependence within the network, facilitating a thorough understanding of the dynamics of stakeholders in the basin.
On the one hand, the planning and implementation of actions for water resource management in the Totorani micro-basin show moderate progress. However, there are still notable gaps between institutional design and local-level implementation. As shown in
Figure 6, the relationship structure is characterized by an intermediate level of coordination, suggesting that although there are formal coordination mechanisms among some actors, including the National Water Authority, EMSAPUNO, SUNASS, the Puno Regional Government, etc., the effective implementation of plans and projects is highly oriented toward a small number of driving institutions, without achieving solid integration with the communities and water user associations.
At the organizational level, gaps in coordination between levels of government are also identified. Interventions led by the Regional Government and the ANA are not consistently operationally coordinated with the local municipalities, which impedes the sustained implementation of conservation policies. On the other hand, the communities of Totorani, Ichu, and Yanamayo are more effective at implementing adaptive practices, such as conserving riparian vegetation strips and protecting springs, despite limited coverage and funding.
Summarizing what is presented in
Figure 6, the above findings suggest that the current challenge is not merely to plan actions technically, but to ensure their coordinated, sustainable, and evaluable implementation. The consolidation of a shared watershed management model, which integrates institutional strategic planning with participatory community action, is critical to achieving effective, resilient management of the Totorani micro-watershed.
3.3. Water Management in the Micro-Basin
The analysis in
Figure 7 highlights one of the most critical gaps in the participatory water management process in the Totorani micro-basin: the low density of economic interaction, that is, the limited financial coordination between institutional and community actors. First, it can be observed that the economic relations are low-density, reflecting, first and foremost, that funding sources are scarce, highly dispersed, and highly concentrated in a small group of public and technical cooperation institutions, where the participation of the private sector and organized communities is marginal.
The qualitative data from the participatory workshops corroborate that the National Water Authority, the National Superintendency of Sanitation Services, and the Provincial Municipality of Puno, which fund specific, short-term projects, finance the majority of conservation and water recharge management actions. This circumstance reinforces the structural dependence on public investment, which limits the financial sustainability of the actions, especially those related to natural infrastructure and the maintenance of wetlands and springs.
Based on all the above, the results in
Figure 7 also allow us to infer that the problem of the financial deficit constitutes a constraint on the consolidation of Totorani’s water management. The enormous institutional dependence and the lack of mechanisms for local generation and financing impede the continuity of conservation work. Overcoming this limitation is therefore proposed through a comprehensive financial strategy based on co-responsibility, the diversification of partners and sources, and the economic valuation of the ecosystem services provided. Establishing a financial strengthening axis is the structuring force that will ensure the environmental and social sustainability of participatory water management processes in Puno.
The results of this research should be considered in the development of public policies, which must be explicitly linked to the specific evidence described in
Section 3.2 and
Section 3.3. More specifically, suggestions for improving water governance, engaging stakeholders, and improving information flows are based directly on the study’s findings on the stakeholder configuration, network analysis, and input–output density.
In the stakeholder analysis conducted for the Totorani micro-watershed, “output density” pertains to the percentage of information, technical assistance, and resources that institutional actors (such as government bodies and technical organizations) provide to local stakeholders. On the other hand, “input density” refers to the extent of responses, involvement, and feedback that local communities or organizations provide to those institutions.
5. Conclusions
The analysis of multiple criteria revealed that 56.01% of the Totorani micro-basin exhibits moderate recharge potential, with 39.91% identified as high, and nearly 3.81% classified as very high. These critical zones are primarily situated in wetlands and floodplains. Through participatory validation, a strong correlation was found between the technical assessments and local knowledge, as community members consistently pinpointed springs and wetlands as key recharge areas.
The basin plays a crucial role in ensuring water security for more than 21,000 individuals. However, conservation endeavors face challenges due to institutional fragmentation; resource constraints; and various threats, such as agricultural expansion, overgrazing, and climate variability. These findings provide compelling evidence for prioritizing wetlands and floodplains in future conservation strategies and underscore the importance of incorporating community perspectives into sustainable water management.
Several limitations of this study must be acknowledged. The AHP methodology heavily relies on expert judgment and stakeholder input, introducing subjective bias into the variable weighting. The sample size for the participatory workshops was insufficient, potentially impacting the representativeness of stakeholder perspectives. Furthermore, the delineated recharge zones signify susceptibility and potential rather than directly measured water fluxes, which could constrain the precision of hydrological assessments. Future research should prioritize expanding stakeholder engagement to improve representativeness, incorporating direct measurements of recharge fluxes, and combining a multicriteria analysis with dynamic climate models to enhance predictive capabilities and facilitate adaptive water management strategies in high Andean ecosystems.
