SQI was fair (0.6) in agroforestry and poor (0.5) in agriculture at Site 2. Altogether, the application of farmyard manure and vermi-compost including the higher vegetation density contributes to enhancing the soil quality in agroforestry systems.

There is generally a strong relationship between farmland price and production capital, as well as with biomass production. From a soil-centric point of view, under dryland agriculture in Australia, we hypothesise that soil available water capacity (AWC) is a key soil property influencing farmland prices and consequently can act as a soil production capital indicator. Here, we relate soil AWC of Australia to median farmland prices using digital soil maps of AWC. The results revealed that AWC from 0 to 100 cm is significantly associated with farmland prices (<em>r</em> = 0.31, <em>p</em>-value<0.05), providing a linear regression to estimate the soil production capital. As long as the AWC (mm) is above 67.6, the coefficient suggests that a 1 mm increase in AWC (mm) results in an increment of 293.6 $/ha in farmland prices in Australia. Additionally, an assessment of the anthropological impact on soils was conducted through phenosoil-genosoil differentiation analysis. We concluded that despite the shared formation characteristics of each pedogenon, soils with the highest AWC were not necessarily chosen for agricultural purposes since European settlement. Furthermore, our findings indicate that phenosoils in Queensland and Tasmania have higher levels of insecurity, likely due to intensified and inappropriate farming that may result in AWC reductions. This analysis provides another perspective to quantify the capital dimension of soil security, valuing its critical role in sustainable food systems and ecosystem services.</p></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"16 ","pages":"Article 100157"},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667006224000315/pdfft?md5=74a7f3dedf6b8e9d59cdcc95d9f7e8de&pid=1-s2.0-S2667006224000315-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141849244","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}

Moreover, a major player in this fight is still missing, consumers. If there is no connection between soil and society then the soil itself may not be valued and it is less likely to be managed sustainably. In this study, we propose the concept of soil footprint, defined as the ratio of soil loss to crop yield, to communicate, quantify, and compare soil security for different crops. It is a versatile concept that can be applied for a multitude of potential practical uses. To showcase some of these potential uses, we used national data to calculate the soil footprint of the ten main crops in Spain. We demonstrate the utility of this metric to compare and rank crops, identify problematic regions, and assess the effect of land management on the soil footprint. The soil footprint indicator offers advantages in terms of simplicity, facilitating easy calculation, comparison, and interpretation by non-technical users.

The current food production system and agricultural policies rely heavily on international supply chains, creating instead a dependence on external sources for food security, while internal sources have been declining for years due to territorial food specialization and monocrops. Since the COVID-19 pandemic and the conflict in Ukraine, global supply chains have experienced unprecedented disruptions due to a combination of factors. The lack of strategic planning to ensure food security continuity in the midst of the geopolitical landscape, supply chain disruption, and soil security overlooked, significantly increase the risk of food and agricultural input shortages, price volatility, and labor disruptions affecting both industrialized and developing countries. In addition, misunderstanding, undervaluation, and underestimation of securing soil among stakeholders, policymakers and legislation are significant factors that exacerbate the problem. As a result, threats to the supply chain compromise the pillars of food security in ways that affect countries unequally, potentially leading to social instability and threatening national and international security.
