“…In the near future, a global overlap of crises is foreseen, such as food, water and energy crises. Prior to the COVID-19 pandemic, more than a quarter of the world's population did not have access to these products [57], with malnutrition affecting one in ten people, especially in developing and less developed countries [58]. The pandemic has worsened the global economic situation, and political conflicts are exacerbating the negative economic and social consequences.…”

Agriculture and related activities generate a significant amount of greenhouse gas emissions with environmental and biodiversity implications. Based on the European objectives proposed by the Green Pact, this paper assesses the carbon footprint of agricultural chains for European OECD member countries. The period analysed is 2000–2019, and the method applied is panel data, specific to OLS models. We opted for three research directions: one is general, one is geographical and one is in temporary dynamics. The general analysis shows that in the European region, the organically cultivated area and economic growth reduce the carbon footprint, while fertilisers, aquaculture production, investments in road infrastructure and agricultural area determine its increase. The geographical analysis outlines the existence of two clusters, one consisting of Member States where agricultural chains reduce their carbon footprint and one consisting of a larger number of Member States, including the major European agricultural powers, where agricultural chains increase the carbon footprint. The temporary analysis reveals that the EU has changed its paradigm since 2008–2009. Economic growth has been slowly decoupling from the carbon footprint since 2016, and the rest of the factors analysed have become more environmental since the late 2010s. The EU has positioned itself towards achieving the objectives set by the Green Pact at a slow pace, justified by the heterogeneity of members’ national characteristics, in addition to its purpose not to harm the food security of the population. In order to achieve the objectives proposed by the Green Pact, it is necessary to focus on more extensive organic farming and traditional production methods, more extensive efforts to reduce nitrogen surplus in fertilizer content, to support short agri-food chains and to identify new production techniques, including the use of nanotechnology and high-performance technologies. Local agricultural chains are crystallizing into a possible solution to the insecurity generated by energy and food crises, political conflicts, pandemics, under the observation that organic products should be excluded from the category of luxury commodity.

“…Worldwide exists a growing crisis in three main categories: energy, water, and food. Alarmingly, the number of hungry people globally has risen for three consecutive years leading to 2017 up to 821 million people [1]. One factor that has contributed to the constant food crisis is the climate change [2].…”

Evaluation of Sugarcane Agroindustrial Wastes as Substrate in Soilless Cultivation of Tomato (S. lycopersicum Linnaeus): Effect of Substrate Composition on Yield Production

et al. 2021

Traditionally, biochar is generally proposed to substitute Canadian Sphagnum peat moss. Sugarcane bagasse, filter press mud and sugarcane bagasse ash were mixed in different ratios and proposed as an alternative to substitute commercial Sphagnum peat moss (SPM) for the soilless cultivation of tomato (S. lycopersicum Linnaeus). The choice of the agroindustrial waste ratio was performed from physical-chemical sample characterization. During vegetable production, an adequate ratio was evaluated based on plant height, substrate pH, number of leaves, yield, and fruit size. The addition of essential macro- and micro-nutrients was performed manually. The results show that as-received materials contain different minerals with a structure that corresponds to the quartz, cristobalite, and feldspar phases. A morphology composed of lamellate structures was observed for sugarcane bagasse, whereas the filter press mud and the sugarcane bagasse ash presented compact agglomerates with a surface area of 1.60, 3.78, and 1.07 m2 g−1, respectively. The properties of each component promote the water adsorption, retention and releasing capacity. Important differences were observed as the quantity of filter press mud increased, but also it is required an amount of sugarcane bagasse above of 18 wt% to reach a superior performance. This work demonstrated that, in adequate quantities, agroindustrial wastes can be used as a soilless substrate for growing tomatoes in greenhouse, reducing their disposal problems.

“…The 2017 World Health Organization (WHO) reports that, with the prevailing climate change situation, more than 50 % of the world population will exist in high water stress areas by 2030 [3]. The intensifying water crisis is also associated to food production since agriculture accounts for 70 % of all freshwater usages [4], hence fresh water supply is one of the most significant future issues [5]. The evident increasing demand for food, energy and water, coupled with the ever-increasing scarcity of land resources, this study aims to tackle these issues by proposing the investment of solar energy into desalination and greenhouse systems.…”

This study presents the effective performance of a sustainable solar driven agricultural greenhouse (GH) self-reliant of energy and irrigation water via desalination. The GH is furnished with infrastructures such as; (i) - an inlet condenser for cool air exchanger and partial water production, (ii) - an internal cavity for crop production (iii) - roof transparent solar distillers (TSD) for solar desalination and partial shading and (iv)- a thermal chimney for natural air ventilation. A mathematical model is developed to predict the performance of the sustainable GH system. A coupled approach of MATLAB/Simulink and computational fluid dynamics (CFD) based on three simulation models were used: solar radiation, thermal energy balance and CFD model. Two parametric studies were carried out. The first one analyzed the effects of different air velocity on the system thermal performance and natural ventilation rate. The second study assessed the effects of different covering material on the transmitted solar radiation. Results from the model shows that 8.5 MJ/m2.day of total solar radiation is transmitted into the GH. The greenhouse air temperature is lowered by 5 °C and humidified by 20%, to satisfy the required conditions necessary for plant growth. Maximum water yield of 11.5 L/m2.day was obtained, aided by the addition of Al-metal net. Additionally, 2.6 kWh/m2.day of power is consumed by the air-cooling condenser. At air velocity of 0.3 m/s, there is a natural tendency of air to flow by draft, due to air temperature difference of up to 4 °C. Furthermore, glass and EVA cover materials transmit 52 and 48% of solar radiation into the GH respectively. The proposed system will enable the parallel production of water and food and enhance economical plant productivity.
