The composition of food baskets can significantly influence the water consumption rate and society’s environmental impact. This study evaluates the sustainability of Iran’s food and nutrition security by evaluating five food baskets using water and carbon-footprint indices. These food baskets are the common Iranian food basket (CIFB), the vegetarian food basket (VFB), the Ministry of Health desired food basket (MHDFB), the Swiss Society for Nutrition food basket (SSNFB), and the Mediterranean food basket (MFB). This study also examines the role of Iran’s agricultural sector under the Paris Climate Change Agreement (COP21). The TOPSIS multi-criteria decision-making method was used to identify the most desirable food basket. The results of this study show that the VFB could be the most desirable alternative to the CIFB. Replacing the CIFB with the VFB causes a 10% and 21% lower water and carbon footprint, respectively. From a 30-year perspective (around 2050), choosing the VFB would reduce the blue water footprint by 19.7 BCM and the gray water footprint by 3.6 BCM compared to the CIFB. According to the provisions of COP21 regarding Iran’s voluntary program to reduce greenhouse gas emissions, the agricultural sector will be one of the sources of greenhouse gas emissions that will face an upward trend. Hence, to adhere to this voluntary commitment, these emissions should be reduced by changing the CIFB to the VFB or reducing emissions in other sectors, such as industry. Choosing the VFB can reduce 10.7 million tons of CO₂ emissions, which can be a significant step for the agricultural sector in Iran in reducing greenhouse gas emissions. Overall, considering the characteristics of farm products (water and carbon footprints) in Iran, a country located in a semi-arid climate, the VFB is recommended.

Water security is a crucial element in the realm of agricultural development, significantly impacting the welfare of farmers and stakeholders throughout the agricultural supply chain. However, the connection between agricultural water security and food security has been relatively understudied. This research seeks to fill this gap by examining the influence of agricultural water security on the food security of smallholder farm households in Ghana. Using principal component analysis, the study classified farmers into two groups: those considered agriculturally water-secure (48.56%) and those agriculturally water-insecure (51.44%), with a threshold set at the 40th percentile. Employing an endogenous treatmenteffect ordered probit model, the research delved into the impact of water security on household food security among smallholder farmers. The analysis revealed several critical factors influencing agricultural water security, including gender, land ownership, non-farm income, access to extension services, credit availability, membership in farmer-based organizations (FBOs), adoption of irrigation, and information sources like NGOs and the Ministry of Food and Agriculture (MoFA). These factors were identified as positively contributing to water security. Conversely, factors such as age, total livestock count, distance to water sources from the farm, and information obtained from fellow farmers hurt agricultural security. Concerning the effect of agricultural water security on food security, the study found that farmers achieving water security witnessed a significant 23% improvement in their food security status. This translated to reductions in mild food insecurity (by 0.8%), moderate food insecurity (by 6.1%), and severe food insecurity (by 17.8%). These findings underscore the importance of government and development partners' support for enhancing agricultural water security among smallholder farmers to improve overall food security.

Abstract In this study, a spatiotemporal disaggregated simulation model was developed based on water–food–energy (WFE) nexus approach to assess water and food supply security considering ecosystem provisioning services. The main components of the developed model in this study (SD-WFE model) are population, water, agriculture, and energy modules. The model, which was developed using system dynamics (SD) approach, was utilized to simulate effectiveness of sectoral municipal, industrial, and agricultural water and energy consumption management and environmental protection policies in improving ecosystem provisioning services during a 20-year period. Through sensitivity analysis utilizing the Monte Carlo model, the study addresses the formulation of sustainable water resource policies across four main categories: water demand management, water supply management, food resource management, and energy resource demand management. Additionally, it explores the integration of policies within an optimal framework. The simulation of proposed solutions revealed that a combination of water demand management and food resource management yielded the most promising outcome. Specifically, the recommended solution entails enhancing water irrigation efficiency by 18% through the expansion of pressurized irrigation network coverage, adjusting cropping patterns by 14%, reducing agricultural product losses by 8% via improved food supply management, minimizing food demand by 9% due to reduced food consumption losses, and achieving an annual 10% increase in crop performance. These selected policies form the foundation for sustainable water resource management strategies.

The food and water crisis that affected Zambia due to prolonged dry spells between 2018 and 2020 is an example of how natural, socioeconomic, and political drivers can produce compounding impacts with long-lasting implications for development. This retrospective disaster analysis explores the risk interactions and early warning early action functioning before and during the event, to draw lessons for anticipation and response to future crises of a similar nature. Combined, the findings feed into the understanding of risk and impacts, which is crucial for improving impact-focused early warning and implementation of early actions. The Government of Zambia’s Disaster Management and Mitigation Unity (DMMU) and Zambia Red Cross Society (ZRCS), key stakeholders in the research, indicated a gap in knowledge of the drivers and impacts of the food and water crisis in Western Province and EWEA functioning at the time, especially the more remote border areas located near the border with Angola and Namibia. No retrospective analysis of the 2018-2020 crisis event has so far included a review of the functioning of the EWEA components at the time at the national and local levels. Therefore, this analysis focuses on Western Province of Zambia, specifically the Sioma, Sesheke and Shang’ombo border districts. The research provides an in-depth perspective on one of the most recent food security crises in Zambia to inform localization and strengthen early warning and early action efforts at the national and community levels. The 2023 drought event in Zambia underscores the critical need for enhanced preparedness for similar crises. This research complements ongoing initiatives for early warning for drought (e.g. through the AWARE project) and efforts within the National Technical Working Group for Forecast-Based Financing, chaired by DMMU, on drought trigger and early action protocol development. This research's focus on hazard and vulnerability interactions aligns with the move to multi-hazard contingency planning in Zambia, led by DMMU. The mixed-methods forensic analysis builds on key informant interviews, focus group discussions, peer-reviewed literature, publicly accessible data and geospatial analysis to consider compounding and cascading risk interactions in 2018–2020 in Zambia, their attendant impacts and risk drivers, and available warnings as well as the communication and early actions associated with them. Complementing ongoing initiatives to strengthen EWEA activities in Zambia for food- and water-related impacts, this study provides contextual information that can support improved targeting, early action selection, warning system design and coordination.

There is a growing concern about limited water supply and water scarcity in many river basins across the world. The agricultural sector is the largest user of freshwater on the planet, with a growing amount of water extracted for livestock systems. Here, we use data from the GLEAM model to advance previous studies that estimated livestock water footprints by quantifying water use for feed production, animal drinking water, and animal service water. We additionally account for the role of trade in accounting for feed water allocations to different animals in different countries and make use of a hydrologic model to estimate feed irrigation water requirements for individual crops at a high spatial resolution. Lastly, we estimate the contribution of livestock water abstractions to water stress at a small river basin scale for the entire globe. We find that feed production water accounts for the majority (>90%) of global livestock water withdrawals, though there is regional variation. Similarly, we find large regional variation in the water consumption per head by livestock species. Despite consuming >200 km³ of water per year, we find that reducing water use in the livestock system alone will rarely reduce water stress in high-stress basins. This study highlights the need for quantifying locally relevant water use and water stress metrics for individual livestock systems.

Recently, different research has been carried out on its potential and usefulness. Due to its nutritional composition, protein contribution, high fiber content and low fat and carbohydrate content, it would be an adequate input to generate products of high nutritional value, characteristics that make it interesting compared to other species. It is used as a complement to commercial diets in a wide variety of animals such as birds, ruminants, non-ruminants, crustaceans, and fish, reducing feed costs by up to 50 %. Likewise, used in remediation processes of a wide range of chemical contaminants with a high elimination rate, they can absorb some dissolved substances and provide oxygen through photosynthesis. It has been indicated that they are low cost of construction, maintenance, easy to operate, have a wide tolerance to growing conditions, are generally easy to harvest, and do not compete with farmland. In the environmental field, it is important to find alternative and innovative raw materials, even without the need to use growth media or fertilizers, however, their acceptance as a food source needs extensive research regarding their nutritional value, large-scale yield, economic market supply and analysis of antinutritive components for human food.
