“…Carbon dioxide emissions were higher from SCM compared with IF in all years. Similar to our results, other studies have shown that CO 2 emissions are greater from plots with manure fertilizers when compared to plots with inorganic fertilizers (Galic et al., 2019; Mapanda et al., 2011). These higher CO 2 emissions with the use of organic fertilizers can be attributed to greater OM availability for microbial respiration in soil.…”

Fertilizer and water management practices have short-and long-term effects on soil chemical and physical properties and, in turn, greenhouse gas (GHG) emissions. The goal of this 4-yr field study was to establish the relationships between soil properties, agronomic practices, and GHG (CO 2 and N 2 O) emissions under different fertilizer and water table management practices. There were two fertilizer treatments: inorganic fertilizer (IF) and a mix of solid cattle manure and inorganic fertilizer (SCM), combined with tile drainage(DR) and controlled drainage with subirrigation(CDS). The cropping system was a maize (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotation. Nitrogen in biomass (BMN) and N in grain (GRN) were measured and used to calculate other plant N parameters. Nitrous oxide and CO 2 fluxes were collected weekly, and their respective cumulative emissions were calculated. The results show that soil organic matter (OM), soil total carbon (C), and soil total nitrogen (N) were greater in SCM than IF by 23.7, 35.2, and 24.4%, respectively. Water table management did not significantly affect soil N and C. Increased CO 2 emissions were witnessed under higher soil OM, soil total C, and total N. Plant N uptake parameters were negatively correlated with N 2 O and CO 2 emissions. Higher plant N uptake can reduce environmental pollution by limiting N 2 O and CO 2 emissions. INTRODUCTIONAgriculture is responsible for 10% of the total greenhouse gas (GHG) emissions in Canada (ECCC, 2020). The use of fertilizer for crop production has increased from 57.6 ( 2002) to 87.6 (2016) kg ha −1 in Canada (World Data Atlas, 2020). Greenhouse gas emissions from agricultural soils have also increased with fertilizer use (Rochette et al., 2008), contributing to climate change.

“…Application of municipal solid waste compost increased soil microbial populations. Our results corroborate those of Galic et al [13] who carried out a long-term fertilization study on the growing season of wheat and maize and finally concluded that the highest CO2 flux in the soil came from the treatment of organic fertilizers. Also Alate et al [14] in a study carried out in Togo on CO2 emissions from the soil in a tomato test field subjected to different water regimes and doses of compost recorded the highest CO2 emissions on plots amended with compost.…”

The objective of the study is to evaluate the respiration of the microbial flora of soils amended with household waste compost under tomato cultivation. The experimental device adopted was that of complete random blocks with three repetitions. The compost was applied in doses of 10 t.ha-1, 20 t.ha-1, 30 t.ha-1 and 40 t.ha-1. To these treatments are added those of absolute control, mineral fertilization (0.2 t.ha-1 of NPK 15-15-15 and 0.1 t.ha-1 of Urea 46% N) and organo fertilization -mineral (10 t.ha-1 of compost combined with 0.1 t.ha-1 of NPK 15-15-15 and 0.05 t.ha-1 of Urea 46% N). Soil samples were taken from the plots at a depth of 0 - 20 cm and incubated in the laboratory for the evaluation of the respiration of the microbial flora. Soil CO2 emission was measured daily for 28 days of incubation using NaOH and 0.1 N HCl as titrant after precipitating the carbonate with barium chloride (BaCl2) solution by alkaline back titration in the presence of the colored indicator (phenolphthalein). The results showed that the application of compost from household waste induced an increase in CO2 emission from the soil (60.67-215.4 mg.kg-1 of soil) and fruit yield of tomato (8.61-36.43 t.ha-1). Thus the application of compost at the dose of 30 t.ha-1 improves soil biological activity and tomato fruit yield.

“…Meanwhile, nitrogen oxides and carbon dioxide are the main contributors to the negative impact on the environment [111], which are generated in irregular and irresponsible agricultural practices [112], electricity generation [113], and transportation [114]. Researchers focused on the combustion processes of conventional solid and liquid fuels with inorganic or biomass additive to reduce pollutant emission [115]. Another effective method for achieving pollutant emission reduction is the application of CO 2 carbon management technologies, including CO 2 capture and storage, which is a competitive solution to mitigate global warming [116].…”

The global COVID-19 pandemic has had strong impacts on national and international freight, construction and tourism industry, supply chains, and has resulted in a rapid decline in the demand for traditional energy sources. In fact, research has outlined that urban areas depend on global supply chains for their day-to-day basic functions, including energy supplies, food and safe access to potable water. The disruption of global supply chains can leave many urban areas in a very vulnerable position, in which their citizens may struggle to obtain their basic supplies, as the COVID-19 crisis has recently shown. Therefore, solutions aiming to enhance local food, water and energy production systems, even in urban environments, have to be pursued. The COVID-19 crisis has also highlighted in the scientific community the problem of people’s exposure to outdoor and indoor pollution, confirmed as a key element for the increase both in the transmission and severity of the contagion, on top of involving health risks on their own. In this context, most nations are going to adopt new preferential policies to stimulate the development of relevant sustainable energy industries, based on the electrification of the systems supplied by renewable energy sources as confirmed by the International Energy Agency (IEA). Thus, while there is ongoing research focusing on a COVID 19 vaccine, there is also a need for researchers to work cooperatively on novel strategies for world economic recovery incorporating renewable energy policy, technology and management. In this framework, the Sustainable Development of Energy, Water and Environment Systems (SDEWES) conference provides a good platform for researchers and other experts to exchange their academic thoughts, promoting the development and improvements on the renewable energy technologies as well as their role in systems and in the transition towards sustainable energy systems. The 14th SDEWES Conference was held in Dubrovnik, Croatia. It brought together around 570 researchers from 55 countries in the field of sustainable development. The present Special Issue of Energies, specifically dedicated to the 14th SDEWES Conference, focuses on four main fields: energy policy for sustainable development, biomass energy application, building energy saving, and power plant and electric systems.
