The Development of Sustainable Agriculture in EU Countries and the Potential Achievement of Sustainable Development Goals Specific Targets (SDG 2)

The development of sustainable agriculture is treated as a priority at the EU level, and the importance and role of agriculture, in general, and sustainable agriculture, in particular, is undeniable. The European Commission pushes for sustainability in agriculture in rural areas across the EU through the common agricultural policy (CAP), and the achievement of the 2030 Agenda for Sustainable Development targets becomes essential. Through our research, we aimed to investigate the status of sustainable agriculture development in EU Member States by assessing the current level of the achievement of SDG 2 targets, as well as the potential achievement of these targets by 2030. Based on data collected from Eurostat, we forecast the evolution of indicators for each country considered until 2030 using the ARIMA model and dynamic indicator analysis. The results obtained suggest, on the one hand, the existence of positive developments at the level of European countries, but also highlight a number of existing disparities, together with evidence of potentially significant deviations from the targets assumed by the 2030 Agenda.

“…ecological risk evaluation of heavy metal elements in the soil of Tangwang village was carried out by calculating their E i and RI, where the toxicity response coefficients of Cu, Hg, As, Pb, Cr, Cd, and Zn were taken as 5, 40, 10, 5, 2, 30, and 1, respectively [30]. As shown in Table 6, the mean values of the E i for each heavy metal element in the soil were E(Hg) = 86.81, E(As) = 80.67, E(Cd) = 67.83, E(Cu) = 8.74, E(Pb) = 4.75, E(Cr) = 3.63, and E(Zn) = 0.64.…”

The impacts of heavy metal pollution in arable soil on agricultural production, environmental health, and the wellbeing of urban and rural residents cannot be overlooked. It has become a significant bottleneck in achieving comprehensive rural revitalization. To accurately grasp the characteristics of heavy metal pollution in suburban cultivated soil, Tangwang Village (a suburb of Huainan City) was subjected to scrutiny. The contents of heavy metals (Hg, Cu, Hg, As, Pb, Cr, Cd, and Zn) in the topsoil of cultivated land in this area were detected, and their spatial distribution characteristics were analyzed using inverse distance spatial interpolation. (1) After conducting a comprehensive analysis and thorough examination of the PMF model sources, it was determined that Cu, Cd, and Zn exhibit a direct correlation with agricultural practices, collectively contributing to a cumulative percentage of 21.10%. Meanwhile, Cr is derived from a combination of sources, including both natural parent materials and human activities, accounting for a total proportion of 24.45%. Notably, lead emissions from automobile exhausts constitute a significant source, while arsenic is primarily associated with dispersed factories and their respective operations, contributing to respective proportions of 36.38% and 18.07%. It is evident that agricultural practices, transportation, and industrial activities are the main reasons for heavy metal pollution in arable soil. (2) The evaluation of geological accumulation indicators reveals that the level of soil arsenic accumulation pollution is mild to moderate (1.199). On the other hand, the cumulative pollution level of Cd, Hg, Cr, and Cu was relatively low (0.462→0.186), whereas the levels of Pb and Zn were below the threshold. (3) The assessment of the ecological risk index revealed that the predominant elements posing potential ecological risks in the investigated region were Hg, As, and Cd, with average Ei values of E(Hg) = 86.81, E(As) = 80.67, and E(Cd) = 67.83, respectively. (4) The human health risk assessment revealed significant differences in the single non-carcinogenic risk values of heavy metals generated by different exposure pathways, with oral ingestion > dermal contact > oral nasal inhalation. Children were more susceptible to the toxic effects of heavy metals compared to adults. Both As and Cr caused an increased risk of cancer in both children and adults, which is a matter of great concern. The results of this study contribute to a more accurate description of the sources of heavy metals in farmland soil. This study indicates that the application of PMF for soil source analysis yields clear results that can be further applied. This research also has potential policy significance as it can help to improve the sustainability of ecosystems by coordinating both environmental and human activities.

“…When following the approach to shorten food chains, a first step ought to be assessing the level of self-sufficiency and then act upon the results [20][21][22][23][24]. To assess the level of self-sufficiency, we need to know which plants grow on local fields and how much of those would be necessary to feed the local population.…”

Land Consumption of Current Diets Compared to the Planetary Health Diet: How many People can our Land Feed?

The way people in many countries eat today is disconnected to the resources and land locally available. In Europe, for instance, too much meat is eaten, but often cannot be fed by local resources. The percentage of non-local and non-seasonal food is tremendous, exploiting other regions and their water reservoirs. Current diets harm eco systems and people’s health. (Re-)regionalising food systems and aligning diets to planetary boundaries could be one way to reconnect people to the food they eat. Before demanding the (re-)regionalisation of food, it should be analysed whether current consumption patterns can be met at all with the regionally available agricultural land. We looked at the region Hesse in Central Germany, calculated and compared land consumption of current diets with the consumption as recommended by the Planetary Health Diet. Our focus is on livestock because land consumption to produce meat, dairy and eggs is relatively high. Our results show that the region is far from being able to feed the current livestock population, that it does not have the land to support the livestock needed to meet current consumption patterns, but that it could support a smaller livestock population according to the Planetary Health Diet, especially if farmers adopt crop rotation systems and extensive husbandry.
