The European Union has outlined a new European Green Deal, whose objectives include increasing the overall quality of the agri-food chain in relation to environmental sustainability, focusing on reducing the use of pesticides and increasing the share of organic in overall production. A Nexus thinking perspective is applied to analyse this topic over a 50-year time horizon (2010–2060) for the agricultural system of the Basilicata Region (Southern Italy), represented by the TIMES Land-WEF, an optimizing, bottom-up energy-technology model, built to investigate the interactions and interrelations between water, energy food and land. The novelty of this modelling approach is the choice of land use as the guiding parameter of the optimization process. The main objectives of the Farm to Fork Strategy are modelled as system constraints and the scenario analysis allows to characterise their effects on the evolution of the agricultural system over the examined time. The results show that the pesticide reduction constraint leads to an increase in land use by organic crops from 24.6 % to 32.4 % in 2060. In particular, this is due to the increased contribution of cereal, forage, olive growing crops, permanent meadows and pastures, which lead to a 46 % reduction in irrigation water consumption. On the other hand, the reduction in inorganic fertilizers is not accompanied by a significant increase in organic crops, but resulted in the reduction of cereal crops.</p></div>","PeriodicalId":93548,"journal":{"name":"Energy nexus","volume":"15 ","pages":"Article 100315"},"PeriodicalIF":8.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772427124000469/pdfft?md5=be5b7beec557834e0a6c2b821ef753fc&pid=1-s2.0-S2772427124000469-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141582655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In some rural places, it is hardness and chlorides that make groundwater or surface water dangerous in terms of the level of toxins. The requirement of hardness and chlorides is influenced because, in large quantities, when it comes to the quality of drinking water, it causes disease. Water is hazardous to the eyes because of its alkaline nature, inhalation organs, and skin problems. The more hardness and chlorides and related irritations there are, the larger the share. A naturally occurring physiochemical mechanism called biosorption enables certain biomass to passively adsorb hardness and chlorides into the biomass's cellular structure. In the lab, five distinct biosorbents were created, including parthenium, rice husk, rapeseed straw, sawdust, and egg cells, in that order. The parthenium biosorbents turned out to be the most successful biosorbents, despite the fact that each biosorbents has a different level of effectiveness in eliminating hardness and chlorides from water. By using the plant based biomass of parthenium, 65 % of chloride removal with 80 % of hardness removal was obtained. Having identified the best biosorbents, we optimized their parameters and took water samples from different sources. In chlorides removal over parthenium biosorbents, the optima dosage of biosorbents is 3.8 g, temperature is 35 °C, pH is 7, contact time is 120 min and optima agitation speed is 120 rpm. In hardness removal over parthenium biosorbents, the optima dosage of biosorbent is 5.4 g, temperature is 35 °C, pH is 6.5, contact time is 90 min and agitation speed is 150 rpm.

However, this potential has not been explored in the South African small-scale sugarcane sector. The current trash management practices of farmers, especially, pre-harvest burning, have huge negative environmental implications. Sustainable management of sugarcane trash could help address several challenges in the sugarcane industry including the high cost of irrigation. Therefore, this study is meant to assess small-scale growers’ trash management practices and their implications on greenhouse gas emissions. It also ascertains the potential for using sugarcane trash in the co-generation of electricity. The study was conducted in two communities in KwaZulu-Natal and Mpumalanga provinces with 330 small-scale farmers. A probit regression was used to determine factors that influence farmers’ trash management practices. Other analyses such as estimations of the amount of available trash, burning emissions and potential energy from sugarcane were informed by previous studies. The findings showed that pre-burning of sugarcane is a common practice among smallholder producers in South Africa. However, some farmers have attempted to move away from this practice opting to leave their sugarcane in the field or use it for compost. The farmers’ burning of sugarcane releases an estimated 0.08 tCO2-e per ha into the atmosphere. In total, the estimated greenhouse gas emissions from sugarcane burning of all small-scale growers in the two provinces are 725 tCO2-e per annum. The findings also revealed that having more land, poor endowment with psychological capital, lack of access to extension, limited resources, and working in silos compound the practice of burning sugarcane. The estimated energy potential from small-scale sugarcane producers in the country, using a 50 % recovery efficiency and 36 % energy conversion efficiency is 150,323.3 MWh.
