Energy is a fundamental element supporting societal development, particularly with the increasing dependency on the Internet of Things. It is also the main contributor to environmental impacts and subsequently, a potential sector for mitigation. Sustainable energy system design considers energy savings and energy efficiency, waste and consumption reduction, process efficiency enhancement, waste heat recovery, and integration of renewable energy. Emerging tools range from advanced Process Integration, modelling, simulation, and optimisation, to system analysis and assessment. This review covers selected emerging studies promoting sustainable system design, including the recent developments reported in the Special Issue (SI) of the 22nd Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (PRES’19). The primary emphasis was to enhance the economic and environmental performance. However, social factors were also highlighted as essential for future sustainable development. The discussion and analysis in this review focus on the most recent developments of (a) heat integration and heat transfer; (b) integrated and newly developed heat exchangers, (c) integration of renewables, and (d) roles in economic and environmental sustainability. The key results are highlighted, and future research ideas are suggested according to their links to a broader context.

“…Optimization models for reservoir operations use an objective function, decision variables, and constraints to define mathematically the costs and benefits related to optimal reservoir operations, water supply allocations and physical characteristics of the water network [8,17]. Many optimization models in Western Canada, such as the Government of Alberta's Water Resources Management Model, are based on the water license system.…”

Water managers’ perspectives on reservoir operations for sustainable irrigation in Alberta

Sustainable reservoir management is essential to ensure the productivity of agriculture and to adapt to a changing climate. Despite progress in reservoir modelling and management with the improvement of computer capabilities and the development of optimization methods, managers and decision-makers still face the challenge of applying the output of more-theoretical optimization models to real-world reservoir operations. This research analyzes reservoir managers' perspectives in Alberta's heavily-allocated South Saskatchewan River basin, in order to improve understanding of the behaviour of reservoir operators under different climatic and hydrological conditions. The method involves in-person interviews with twelve water managers of Southern Alberta's irrigation districts. The data collected suggest that seniority-based allocation priorities are generally not strictly applied. Instead, cooperation between districts and between irrigators within a district indicates that water allocations are driven principally by the infrastructure capacity on a river-basin-scale basis. Of additional importance is recognition of the "day-by-day" approach adopted by all water managers interviewed who will "never sacrifice today for tomorrow". Moreover, water managers do not apply annual or multi-year water deficit-distribution strategies, but instead impose variable water rationing for all irrigators at the beginning of a growing season. The contribution of this research is to provide real-world data and a better understanding of water managers' perspectives that may lead to more valuable outcomes from modelling studies, and results that may be more readily adopted by water managers.

Resource use and economic impacts in the transition from small confinement to pasture-based dairies

In recent years, many livestock farms have transitioned from total confinement housing to a pasture-based system in an effort to reduce labor and production costs and improve profitability. There is a growing interest in biogas recovery among livestock producers to reduce energy costs and manure odors but the economic benefits of anaerobic digestion (AD) on small farms is not well known. A comprehensive analysis was conducted using the Integrated Farm System Model (IFSM), to describe, evaluate and compare the farm performance and economic impacts of representative dairy farms in Michigan transitioning from conventional confinement to seasonaland pasture-based systems, and evaluate the potential for integration of an AD in the confinement and seasonal pasture systems. The results in farm performance present higher milk production per kilogram of feed in the confinement systems, followed by the seasonal pasture and the annual pasture systems. In the economic analysis, the annual pasture-based system had the greatest net return to management and unpaid factors followed by the seasonal pasture and confinement systems. The addition of an AD on a 100-cow, total confinement dairy decreased the net return to management and unpaid factors by 20%. When anaerobic digestion was added to the seasonal pasture with an increased land base for cash crop production and an imported manure volume equivalent to a 500-cow dairy, the net return to management and unpaid factors increased 269% compared to the seasonal pasture dairy alone.
