- Agriculture is one of the most water- and energy-intensive sectors of the economy, consuming about 70% of global freshwater withdrawals. Access to clean and affordable water for irrigation is an essential step towards guaranteeing water and food security, improving incomes and living standards, decarbonizing an energy-intensive sector and attaining the United Nations Sustainable Development Goals (SDGs), in particular SDGs 2 (Zero Hunger), 6 (Clean Water and Sanitation), 7 (Affordable and Clean Energy), and 13 (Climate Action). Ensuring access to water for irrigation, as well as for other agricultural (i.e., livestock watering), domestic, and industrial purposes is a global challenge, and it is more challenging in remote areas where the grid connection is often not available. Solar-powered pumping systems represent a renewable solution for the decarbonization of the irrigation sector worldwide. While solar water pumping systems were used in the past to supply water for irrigation, livestock, and domestic purposes only in remote locations without access to the electric grid, the drastic drop in photovoltaic (PV) modules prices has made the technology also competitive for on-grid applications. This chapter reviews the configurations of solar water pumping systems for irrigation, highlighting the water–food–energy nexus aspects and recent advances, reviewing case studies, and analyzing the economics and current and future challenges.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The agricultural and food processing industries are considered key sectors aligned with sustainable development goals, as they play an important role in sustainable rural development. About 30% of global energy is used in these sectors, particularly thermal energy in both heating and cooling applications. Research considers solar energy technologies to be promising ways to increase system flexibility and lead to climate mitigation impacts. Different types of solar heating and cooling systems can supply a wide range of desired operating temperatures for various applications in agricultural and food processing systems. The main applications of solar thermal energy systems in the agricultural and food processing industries are solar air heaters for drying and dehydration processes, solar water heaters for both heat and food processing systems, solar cooking systems, solar heating and cooling systems for maintaining greenhouse climate, and solar-powered cooling systems for both food processing and space cooling. Furthermore, some innovative active and passive integrated solar systems such as the solar-blind concept remain underdeveloped. Further advances in solar energy integration systems in the agricultural and food processing industries will lead to considerable climate mitigation impacts as well as more resilient energy management in this sector.
