“…Many advances have contributed to that trend, and technological advances and grower adoption of those advances must continue to meet the stated goal. Harmel et al (2020) outlined several actions that are needed to improve global water security, and those that could be directly applied to cotton are listed in table 2.…”

Highlights Over the last 40 years the amount of irrigation water used by cotton in the United States has decreased while yields have increased leading to a large increase in crop water productivity (CWP). Many factors have contributed to improved CWP, such as improvements in water delivery systems. Irrigation scheduling technologies have also contributed to improved CWP; however, farmer adoption of advanced scheduling technologies is still limited and there is significant room for improvement. Increased yields from improved cultivars without an increase in water requirements has also been important for CWP. Continued developments in sensor technologies and improved crop simulation models are two examples of future strategies that should allow the U.S. cotton industry to continue an upward trend in CWP. Abstract. Over the last 40 years the amount of irrigation water used by cotton in the United States has decreased while yields have increased. Factors contributing to higher water productivity and decreased irrigation water use include migration of cotton out of the far western U.S. states to the east where more water requirements are met by rainfall; improved irrigation delivery systems with considerable variation in types and adoption rates across the U.S.; improved irrigation scheduling tools; improved genetics and knowledge of cotton physiology, and improved crop models that can help evaluate new irrigation strategies rapidly and inexpensively. The considerable progress over the last 40 years along with the promise of emerging technologies suggest that this progress will continue. Keywords: Cotton, Crop water productivity, Irrigation, Sustainability, Water use efficiency.

“…According to World Health Organization (WHO) estimation due to pollution problems, almost 2 billion people worldwide do not have access to clean drinking water [6]. Recharging aquifers, encouraging water use efficiency, and implementing effective irrigation techniques are all examples of initiatives that are essential to sustainable groundwater management [7]. Reducing pollution and over-extraction is largely dependent on the establishment of strong monitoring programs, legal frameworks, and public awareness initiatives [8].…”

Groundwater is an important natural resource in the North China Plain (NCP) with high economic benefits and social significance. It fulfills 60% of drinking and 70% of irrigation water requirements. In this review, the information is retrieved from high-quality articles published in MEDLINE and other sources. We saw that groundwater is declining faster (>1 m yr−1) and polluting with NO3− (>30 mg L−1) due to excessive water pumping and application of a nitrogen (N) fertilizer, respectively. The water pumping (>600 mm ha−1 yr−1) for agricultural purposes in the region is higher than the recharge amount (<200 mm yr−1). The low recharge is the result of low rainfall (<600 mm yr−1), and high evapotranspiration (>800 mm yr−1) under the impact of dominant vegetative characteristics of winter wheat–summer maize (WW-SM) rotations, covering >80% of the land. Furthermore, N application exceeds the crop assimilation capacity (>250 kg ha−1 yr−1) and leach deep down (>50 kg ha−1) as well as loss in the atmosphere. Presently, Beijing, Tianjin, and Hebei are ecologically the most affected areas. We suggest that excessive water and N fertilizer use for intensive cropping systems should be controlled by paying high attention to groundwater-friendly farming practices. In addition, artificial groundwater recharge options and their safe utilization would be explored across the region to replenish aquifers. This literature review contributes valuable insights to the knowledge bank and offers a foundation for further research and policy development.

“…Even as a global pandemic disrupts markets, stalls labor, and upends supply chains, researchers around the globe continue to pursue solutions to the challenges facing agriculture and its ability to feed, clothe, and fuel humanity while sustaining our natural resources and environment (Henry, 2020). Population growth, demographic shifts, accelerated eutrophication, and climate change persist as wicked problems threatening the security of the food-water-energy nexus (Chaubey et al, 2016;Harmel et al, 2020;United Nations, 2018;WWAP, 2014). Successful adaptation to, and mitigation of, these challenges will necessitate technology-driven innovations that harness and apply abundant data that were previously unfathomable in their current availability, precision, scale, and volume (Kharel et al, 2020).…”

“…The role of data solutions to agriculture's challenges is no different, and research advances will require larger volumes of data with corresponding metadata and multilocation, transdiscipline collaboration, along with a transformation in methods to support more complex and integrated analyses leveraging artificial intelligence and machine learning. Further, socioeconomic aspects will need to be fully incorporated into technology development, decision making, and policy formulation, as will the expanded participation of all relevant stakeholders to ensure that agricultural research innovations are successful within human dimensions and constraints (Harmel et al, 2020).…”

For agricultural research to seize the potential of data-driven technologies, profound changes are needed in the full spectrum of data management, highlighted by a shift of researchers, institutions, and agencies toward a culture of data stewardship. The USDA-ARS established the Partnerships for Data Innovations (PDI) in 2019 to achieve this transformation from within. From the onset, PDI has integrated its customer-partners in developing and implementing state-of-the-art digital tools, leveraging off-the-shelf technologies when advantageous. In its short life, PDI has transformed more than 100 projects, from projects catalyzing collaborative efforts and underpinning information management to those salvaging end-of-life data repositories. Empowered by this active inclusive partnership and through sharing digital solutions on a "Digital Research Workbench" within the ARS Agricultural Collaborative Research Outcomes System infrastructure, PDI hopes to accelerate agricultural research through standardization, automation, and integration and to help usher in a culture of digital age data stewardship.
