    Linked to municipal water sources, the Cachipamba Ecological Park suffers from lack of water management due to climate change. The objective of this study is to propose a drip irrigation system integrated with Sustainable Urban Drainage Systems (SUDS) to optimally use water, reduce the amount of runoff and improve resilience to climate change with a certain case study model for an urban green space in a semi-arid area. Methods: The approach used in this thesis was mixed, including: (1) analysis of available hydrological series (1976-2017) to determine maximum rainfall and return periods; (2) hydraulic modeling of the irrigation system with a flow rate of 45.89 m3/h (90% efficiency); (3) design of a SUDS that had capacity for extreme events (180 mm/h) and; (4) social assessment, conducted through workshops with local community members and by interviewing community experts. Results: The system demonstrated: (a) 36.03% potable water savings with rainwater harvesting; (b) effective storm management for a 100-year return period; (c) irrigation coverage of 16.67 mm every three days. The SUDS infrastructure proved to be able to infiltrate 40% of the runoff and improve water quality (85% solids removal). Discussion and conclusions: The results confirm the success of integrated systems for sustainable water management in urban areas. Although continuous monitoring is necessary to observe and maintain biological parameters, the design outperforms conventional alternatives in terms of climate adaptability and efficiency. Future research will need to study the long-term impacts on biodiversity, as well as its replicability in other urban contexts.

    Retos en la conversión del sistema de riego gravitacional a métodos más eficientes en los cultivos de papas, maíz y claveles de la comunidad de Carrillo, parroquia Cusubamba, cantón Salcedo.

    Objective: The technical, economic, and social challenges of transitioning from gravity irrigation to more efficient pressurized methods (sprinkler and drip) in the Carrillos community (Cusubamba, Salcedo) were analyzed, given their importance for water security and the production of potatoes, corn, and carnations. Methodology: A mixedmethods case study was conducted, including topographic surveys and infrastructure inventory,flow measurements and water balance, estimation of waterrequirements using FAO-56 (ETo/ETc), infiltration and soil moisture tests, and a technical-economic comparison of gravity, sprinkler, and drip irrigation; in addition, interviews were conducted with producers to assess technological acceptance and water governance. Results: The gravity system showed overall efficiencies below 45% and conveyance and application losses exceeding 50%, with flow rates dropping from 27 L/s at the intake to approximately 11–10 L/s at the plot; cumulative water deficits were identified, especially in carnation. Sprinkler irrigation raised efficiency to ~78–80% for potatoes and corn and drip irrigation to ~92% for carnations, reducing water waste by 40% to 70%; 85% of the area had slopes under 8% suitable for sprinkler irrigation; 65% of farmers expressed willingness to adopt technology if financing was available, while small landholdings (≈70% with less than 1 ha) emerged as a barrier. Conclusions: Conversion istechnically feasible, economically justifiable, and environmentally necessary, provided it is integrated with clear distribution rules, planned operation and maintenance, micrometering, and financing schemes; scaling up the modernization with strengthened community governance is recommended to improve water efficiency, stabilize yields, and enhance climate resilience in Andean ecosystems.
