“…The Ogallala Aquifer, one of the largest aquifers in North America, serves as a pertinent example of the challenges faced by regions heavily reliant on groundwater for agriculture. Overexploitation of such resources can lead to significant water level declines, posing threats to food security and the sustainability of agricultural economies (Gowda et al, 2019). Similar challenges might be inferred for regions in South West Nigeria, where water resources are crucial for agriculture and local livelihoods.…”

This research explores Integrated Water Resource Management (IWRM) in South West Nigeria, emphasizing its diverse ecological landscapes and burgeoning population. This study aimed to dissect the historical, socio-economic, and environmental facets of water resource management, aiming to pinpoint existing gaps and discern both challenges and avenues for prospective advancements. Employing an exhaustive methodology that amalgamated literature reviews, pertinent case studies, and stakeholder feedback, the investigation illuminated the region's profound history in water management, the pivotal role of local communities, and the ramifications of various strategic interventions. The results indicated that, despite notable progress in IWRM, persistent challenges such as water pollution, rapid urbanization, and the impacts of climate change remain. The research accentuated the criticality of community participation, holistic stakeholder collaboration, and the harmonization of age-old practices with contemporary technological innovations. In conclusion, the future of water resource management in South West Nigeria teeters at a crucial juncture, presenting opportunities to carve a sustainable trajectory. The recommendations advocate for augmented investments in research, nurturing community-driven initiatives, and embracing adaptive strategies to preemptively address anticipated shifts in water demands and supplies. Keywords: Integrated Water Resource Management, South West Nigeria, Community Engagement, Water Security, Stakeholder Collaboration.

“…The aquifer provides water for approximately 1.9 million people and has been instrumental in the development of the robust agriculture economy of the Great Plains region. The Ogallala Aquifer region accounts for about 30% of all irrigation in the US [6] and more than 30% of US crops and livestock are produced in this region [9].…”

The Ogallala Aquifer underlies 45 million ha, providing water for approximately 1.9 million people and supporting the robust agriculture economy of the US Great Plains region. The Ogallala Aquifer has experienced severe depletion, particularly in the Southern Plains states. This paper presents policy innovations that promote adoption of irrigation technology, and management innovations. Innovation in Kansas water policy has had the dual effects of increasing the authority of the state to regulate water while also providing more flexibility and increasing local input to water management and regulation. Technology innovations have focused on improved timing and placement of water. Management innovations include soil water monitoring, irrigation scheduling, soil health management and drought-tolerant varieties, crops, and cropping systems. The most noted success has been in the collective action which implemented a Local Enhanced Management Area (LEMA), which demonstrated that reduced water pumping resulted in low to no groundwater depletion while maintaining net income. Even more encouraging is the fact that irrigators who have participated in the LEMA or other conservation programs have conserved even more water than their goals. Innovative policy along with creative local–state–federal and private–public partnerships are advancing irrigation technology and management. Flexibility through multi-year allocations, banking of water not used in a given year, and shifting water across multiple water rights or uses on a farm are promising avenues to engage irrigators toward more sustainable irrigation in the Ogallala region.

“…Greater saturated thickness and recharge in the northern part of the aquifer (Nebraska and South Dakota) could feasibly sustain pumping while lower recharge and greater evaporative demand in the southern (Texas and New Mexico) and west-central (Colorado, Kansas, and Oklahoma) parts of the OAR make long-term pumping less sustainable (Deines et al 2020). Although widely varying groundwater policies, governance structures, socio-economic conditions, and climate change impacts exist across the OAR (Gowda et al 2019), improved irrigation management at the farm level can have a significant impact in conserving groundwater in the OAR (Ajaz et al 2020). This special issue of Irrigation Science highlights interdisciplinary approaches to improving irrigation management in the OAR through in-field management, deployment of various technologies, and strategic economic or modeling analyses.…”
