SANCHEZ LAZO, Angie Vanussa  and  LORA LOZA, Miryam Griselda. Revenue collection and financial efficiency in irrigation projects: systematic review. Revista InveCom [online]. 2026, vol.6, n.3, e603068.  Epub Dec 15, 2025. ISSN 2739-0063.  https://doi.org/10.5281/zenodo.17561831.

The objective of this study was to synthesize the existing literature on revenue collection and financial efficiency in irrigation projects in various countries. The PRISMA methodology was used to conduct a systematic review of international databases such as ProQuest, Scopus, Google Scholar, PubMed, Redalyc, and EBSCO. The search was conducted using keywords in Spanish and English related to irrigation projects and financial efficiency, considering publications between 2015 and 2025, without restriction by country. The results show that water tariff collection is a fundamental pillar for the financial sustainability of irrigation projects; however, in many cases, these revenues do not cover operating and maintenance (O&M) costs, compromising their viability. It is observed that tariffs established per surface area are insufficient, while volumetric tariffs can increase revenues and promote more efficient water use. Likewise, technological modernization, drip irrigation, and the reuse of treated water are identified as key strategies for improving the profitability and sustainability of the system. It is concluded that strengthening collection mechanisms, modernizing infrastructure, and encouraging community participation are essential actions to ensure the financial and operational efficiency of irrigation projects.

Keywords : water collection; financial efficiency; irrigation projects.
