Innovative and Critical Issues in Natural Resource Management and Exploitation

The International Union for Conservation of Nature (IUCN) conducts critical international studies and offers recommendations on the sustainable conservation, use, and management of protected areas worldwide by setting targets within the framework of the Nature 2030 goals and the Green List standards. These initiatives are essential for protecting designated areas and encouraging their use through nature-based and community-based solutions. The success of implementing these solutions depends on the effectiveness of the local legal regulations that are currently in place. This article argues that developing a common language and norms between global and national conservation frameworks, along with the efficiency of the national legal framework, plays a crucial role in facilitating the goals of the protection, use, and management of global protected areas. This study evaluates how the reflections and presence of IUCN’s globally significant targets are addressed within Türkiye’s national legal framework and policy level. The article evaluates global and national legal texts in Türkiye for social, environmental, and economic sustainability, comparing them with the Nature 2030 and Green List standards through methodologies such as word matching, comparison, and compatibility analysis. For the development of laws and policies that align with Türkiye’s global goals for the protection, use, and governance of protected areas regarding language and normative standards unity, the article highlights the importance of nature- and community-based national policy norms in achieving global protected area targets. The article’s results highlight the absence of community-based norms such as participation, governance, transparency, and equality, despite international consensus on norms like planning, area management, and the rule of law for the effective management of protected areas in Türkiye.

Resource-based regions face particular challenges in achieving sustainable land-use transformation due to their entrenched development patterns. Through an integrated approach (super-efficiency SBM, Global Moran’s I, synergistic modeling, and SNA), this study analyzes Shanxi Province’s land-use efficiency dynamics (2015–2021), revealing (1) an N-shaped efficiency trajectory with core-periphery polarization stable high-efficiency clusters (Taiyuan/Yangquan/Luliang, mean > 1.1) versus fragmented northern mining zones and stagnant southern regions; (2) deficient spatial coordination (Moran’s I < 0) and failed capital-city spillovers, with only 2/10 cities achieving positive synergy; and (3) network instability (density = 0.14–0.29) featuring paradoxical power shifts in the emerging mining hub Shuozhou (degree = 100) outperforming traditional cores. Based on these findings, this study proposes policy recommendations from the perspective of regional policymakers, focusing on establishing provincial-level land resource utilization planning, promoting coordination among cities in terms of land resource utilization at the municipal level, and improving land resource utilization efficiency through environmental regulations. This study offers a new perspective on regional coordination for sustainable development in resource-based regions by conducting research at the provincial level, advancing policy suggestions at the meso-policy level for the green transformation of resource-based cities, and providing theoretical support for promoting the intensive and efficient utilization of land across cities in specific regions.

The establishment of the Ministry of Natural Resources and the Ministry of Agriculture and Rural Affairs of China marks the integrated installation of centralized and unified supervision of agricultural natural resource assets. It is of great practical significance to explore comprehensive systems of supervision of agricultural natural resource assets with the aim of super-ministry system restructuring; this could provide support for the development of new quality agricultural productivity. This paper mainly discusses the value objective and the approach of the rule of law concerning comprehensive supervision of agricultural natural resource assets in China with the aim of super-ministry system restructuring and codification. It combines a normative analysis of law with an economic analysis to address the current laws and regulations concerning the supervision of agricultural natural resource assets and summarize the existing problems of the supervision system. From the perspective of game equilibrium, the paper explores the reasonable expected utility of multiple entities under comprehensive supervision of agricultural natural resource assets. The results show the following: (1) The value objective of comprehensive supervision of agricultural natural resource assets should include process-oriented, multi-participation asset accretion and technological innovation. (2) Different supervision departments have different objectives and interests with respect to taking risks. (3) From the perspective of game equilibrium, an effective balance between development and use and comprehensive supervision of agricultural natural resource assets calls for a reconstruction of the structure of rights (powers) and for practical systematic selection. Therefore, this research recommends that efforts to improve the legal systems of comprehensive supervision of agricultural natural resource assets in China should take comprehensive supervision legislation as an approach to solving the issues and should also take comprehensive central and local cohesion as realization mechanisms, highly integrated and coordinated in legislation, while allocating to various institutions responsibility for the efficient use of agricultural natural resource assets, and the protection of rural green ecological environment, to promote the revitalization of rural ecology, and the security of agricultural resources.

The living lab (LL) concept has a significant potential to drive sustainable development, particularly in the bioeconomy sector, by assisting communities in improving their quality of life whilst also considering the environmental impact. In this context, the main research question was the following: is there any specific mechanism through which living labs operate under the sustainable development concept? We reviewed 120 papers addressing this topic and performed a bibliometric analysis on the linkage between sustainability and living labs by applying the methodology of a systematic review. We concluded that living labs can drive innovation and experimentation in sustainability, which can be transposed into tangible solutions to economic, environmental, and social problems. The role of living labs in the transition to a bioeconomy is discussed and further research directions are presented. Full article

High-resolution remote sensing platforms are crucial to map land use/cover (LULC) types. Unmanned aerial vehicle (UAV) technology has been widely used in the northern hemisphere, addressing the challenges facing low- to medium-resolution satellite platforms. This study establishes the scalability of Sentinel-2 LULC classification with ground-linked UAV orthoimages to large African ecosystems, particularly the Burunge Wildlife Management Area in Tanzania. It involved UAV flights in 19 ground-surveyed plots followed by upscaling orthoimages to a 10 m × 10 m resolution to guide Sentinel-2 LULC classification. The results were compared with unguided Sentinel-2 using the best classifier (random forest, RFC) compared to support vector machines (SVMs) and maximum likelihood classification (MLC). The guided classification approach, with an overall accuracy (OA) of 94% and a kappa coefficient (k) of 0.92, outperformed the unguided classification approach (OA = 90%; k = 0.87). It registered grasslands (55.2%) as a major vegetated class, followed by woodlands (7.6%) and shrublands (4.7%). The unguided approach registered grasslands (43.3%), followed by shrublands (27.4%) and woodlands (1.7%). Powerful ground-linked UAV-based training samples and RFC improved the performance. The area size, heterogeneity, pre-UAV flight ground data, and UAV-based woody plant encroachment detection contribute to the study’s novelty. The findings are useful in conservation planning and rangelands management. Thus, they are recommended for similar conservation areas. Full article

Jaboticaba, a popular Brazilian fruit, has recently garnered scientific interest due to its nutritional properties and high levels of bioactive compounds. However, this fruit is highly perishable due to its high moisture content and physical–chemical structure. Therefore, it is imperative to employ methods for preserving it and explore its potential as a food resource. This study investigates the use of a spray drying method to dehydrate whole jaboticaba fruits. The effects of air temperature (T) ranging from 67.9 to 132.1 °C, air flow rate (AF) from 1.54 to 1.86 m³/min, maltodextrin concentration (M) from 8.9 to 41.1%, and feed flow rate (FF) from 0.36 to 0.84 L/h on the moisture content, drying yield, and bioactive compounds (total phenolic, total flavonoid, citric acid, and ascorbic acid contents) were quantified. The results indicate that spray drying can produce a powder with reduced moisture content levels, a satisfactory drying yield, and high levels of bioactive compounds if performed under specific conditions. An optimization study using desirability analysis shows that having T, AF, M, and FF at 132.1 °C, 1.86 m³/min, 15.0%, and 0.4549 L/h, respectively, is the optimal condition for the studied variables. Spray drying has proven to be a very promising alternative for jaboticaba processing, enabling better applications as a food resource. Full article

Post-recycling sodium polyacrylate (SPA) derived from the selective recycling of personal hygiene products was tested as a potential key component of soil modifiers. Recycled SPA in combination with layered aluminosilicate (halloysite) with the sorption capacity of fertilizers allows for the creation of a fully functional, original system responsible for both water retention in soil and controlled dosing of fertilizers. The use of post-recycling SPA (possibly partially supplemented with virgin SPA) is advantageous for the natural environment. The results of different water types retention in post-recycling SPA (deionized water, rainwater, tap water) are discussed. The most beneficial effects of R-SPA swelling and water accumulation are achieved when it comes into contact with rainwater. The clear impact of Mg²⁺ ions on the sorption capacity of R-SPA introduces the need for a technological compromise between the solution composition (N, P, K or N, P, K, Mg) affecting its fertilization value and the possibility of obtaining maximum R-SPA swelling. The sorption capacity of R-SPA can be slightly increased by using R-SPA/V-SPA mixtures, but R-SPA still plays a decisive role in this system. The possibility of technological adjustment of the leaching rate of fertilizer components under dynamic conditions using different combinations of (R-SPA/V-SPA)/HAL was demonstrated by column tests.
