“…Some current bottlenecks include the photosynthetic process itself, and technological limitations in harvesting and processing biomass, as well as extracting useful materials. Most commercial biomass sources are from terrestrial plants, so the availability of conventionally arable land and freshwater is another important consideration ( OECD, 2011 ). In addition, plant evolution has led to limited genetic diversity when compared to cyanobacteria or microalgae ( Häder, 2022 ).…”

Current work in photosynthetic engineering is progressing along the lines of cyanobacterial, microalgal, and plant research. These are interconnected through the fundamental mechanisms of photosynthesis and advances in one field can often be leveraged to improve another. It is worthwhile for researchers specializing in one or more of these systems to be aware of the work being done across the entire research space as parallel advances of techniques and experimental approaches can often be applied across the field of photosynthesis research. This review focuses on research published in recent years related to the light reactions of photosynthesis in cyanobacteria, eukaryotic algae, and plants. Highlighted are attempts to improve photosynthetic efficiency, and subsequent biomass production. Also discussed are studies on cross-field heterologous expression, and related work on augmented and novel light capture systems. This is reviewed in the context of translatability in research across diverse photosynthetic organisms.

“…Other drivers that are aff ecting water use for agriculture include competition for water from biofuel production, for example, for sugarcane or maize as well as increased demand for energy production from hydropower, which might improve or reduce irrigation water availability, depending on the location and timing of generation capacity, and water use for thermoelectric power generation. Finally, climate variability and climate change, including both more extreme events and higher temperatures are increasing pressure on total and agricultural water demands (Ringler, 2011).…”

Agricultural water use includes a continuum from purely rainfed to fully irrigated systems. Growing pressures on limited water supplies from domestic, industrial, and environmental uses will likely lead to a decline in water availability for food production. Similarly, income growth and urbanization lead to dietary shift s that require more water resources per calorie consumed, putting further pressures on water supplies. As a result, semiarid and arid countries continue to increase net imports of food. Crop water use for sugarcane (Saccharum offi cinarum L.), maize (Zea mays L.), soybean [Glycine max (L.) Merr.], and fruits are expected to grow over time, whereas water use for wheat (Triticum aestivum L.) and rice (Oryza sativa L.) are expected to decline aft er 2030. Th ese projections include substantial improvements in water use effi ciency at the fi eld, farm, and river basin scale over the coming decades in response to growing water scarcity. If these effi ciency improvements are not achieved, future crop water demands would be even larger. Although water resources are a key limiting factor for future food security, policy and investment options to reduce agricultural water use exist on both the water supply and demand side; but political will and ingenuity are needed for their implementation.
