The continuous improvement of international protection awareness has dramatically increased the number of protection organizations and promoted various reserve-naming methods. However, the existing global natural reserves have either fully or partially overlapped, thereby allowing the same region to hold various international titles, resulting in serious issues, which are especially manifested in the boundary delimitation process of natural reserves. Therefore, delimiting the titles of reserve borders will become an enormous challenge in protected-area governance worldwide. This study conducted an in-depth investigation of the technical methods for delineating the spatial boundaries of natural reserves. Taking Jiangshan Nature Reserve in China as the case object, the Candidate Area–Natural background–Heritage Resource–Construction (C-NHC) framework was constructed, and the boundaries of the new reserves were delineated. This study has changed the status quo of the spatial overlap of the reserve through the quantitative evaluation of the conflict patches and the triple optimization of the boundary of the reserve. The area of the new reserve is 150.524 km2, which is 6.682 km2 larger than the original one. The original reserves are all included within the scope of the new one. This study provides guidance and new insights into the boundary delineation of integrated nature reserves worldwide.

As a first approach to the conservation status of the hypogeous environment we studied six troglobyte arthropods in 19 chasms and caves in four natural reserves in Catalonia: Garraf, Sant Llorenç del Munt i l’Obac, El Montseny, and El Montnegre i El Corredor. The target species were four leiodid beetles, Troglocharinus ferreri ferreri (Reitter), Troglocharinus kiesenwetteri sanllorensi (Zariquiey), Parvospeonomus canyellesi (Lagar), and Parvospeonomus urgellesi (Español), a pseudoscorpion, Troglobisium racovitzai (Ellingsen), and an isopod, Stenasellus virei Dollfus. Other findings of interest herein are the description of Dicranophragma relictum Mederos (Diptera: Limoniidae) and new citations for Catalonia of Troglobisium racovitzai, the beetle Linderia armata (Schaufuss), and the dipterans Dactylolabis sexmaculata (Macquart) i Elliptera hungarica Madarassy.

Abstract In Russia 45156.3 tons of waste were generated from agriculture, forestry, hunting, fishing and fish farming according to statistics for 2020. 1200 tons of manure are formed per day in Tyumen region. The volume of accumulation of such manure is 432,000 tons per year. But at the same time, manure is a source of greenhouse gases, their amount can be: CO2 – 21.5 million м3, methane – 12.9 million м3 per year. Due to its unique chemical and biological properties, diatomite is widely used in many areas of agriculture. It can be used as an excellent adsorbent, fertilizer, food additive for animals and birds, an environmentally friendly contact insecticide for pest control of grain, fruit and ornamental plants. To restore the lost fertility (0.6% per year (2032.2 hectares), it is necessary to carry out soil protection measures, as well as to add mineral and organic fertilizers to the soil (11.7 million tons of organic fertilizers annually for 15 years). The availability of a large amount of mineral resources and bird manure makes it possible for researchers to develop the composition and technologies to create organomineral fertilizers.

La réserve naturelle forestière de Vyanda subit des pressions anthropiques permanentes et risque de disparaître avant qu’elle ne soit étudiée. La présente étude a pour objectif de déterminer la composition et la diversité de la végétation de cette réserve et de motiver la prise des mesures de conservation localement adaptées. L’étude a procédé par l’inventaire de la végétation suivant la méthode du relevé phytosociologique de Braun Blanquet (1932). Des spectres bruts et pondérés des formes biologiques, des types de diaspores et des types phytogéographiques ont été établis. Les résultats de l’inventaire floristique ont fait état de 108 espèces réparties en 81 genres et 41 familles. Sur le plan des formes biologiques et des types de diaspores, les phanérophytes et les sarcochores dominent tandis que les hémicryptophytes de même que les sclérochores sont bien représentés. Sur le plan phytogéographique, l’étude a mis en évidence une forte représentativité de l’élément paléo-africain, de l’élément soudano-zambézien et de l’élément guinéo-congolais. Ces spectres attestent la spécificité de cette réserve comme forêt claire du type miombo tout en mettant en évidence l’impact des perturbations dont elle est victime. L’étude met en évidence la richesse spécifique de la réserve et démontre l’intérêt qu’il y a de prendre des mesures visant à arrêter les perturbations anthropiques et à bien gérer ce milieu naturel. Sa diversité est en effet grande comparé aux autres réserves naturelles du voisinage.   English title: Phytosociological analysis of the vegetation of the Vyanda natural forest reserve in southwestern Burundi The Vyanda natural forest reserve is under constant human pressure and is in danger of disappearing before it is studied. The objective of this study is to determine the composition and diversity of the vegetation of this reserve and to motivate the taking of locally adapted conservation measures. The study carried out a vegetation inventory using the Braun Blanquet (1932) phytosociological approach. Spectra of life forms, phytogeographical elements and diaspores morphology were established. The results of the floristic inventory revealed 108 species divided into 81 genera and 41 families. In terms of life forms and types of diaspores, phanerophytes and sarcochores dominate when hemicryptophytes as well as sclerochores are well represented. Phytogeographically, the study revealed a strong representativeness of the Paleo-African element, the Sudano-Zambezian element and the Guinean-Congolese element. These spectra attest to the specificity of Vyanda natural forest reserve as an open forest of the miombo type while highlighting the impact of the disturbances that affect it. The study highlights the specific richness of the reserve and its diversity and demonstrates an urgent need to take measures to stop anthropogenic disturbances and well managing this natural ecosystem. Its diversity is indeed great compared to other natural reserves in the region.

Butterfly-based handicraft activities are usually performed around or within natural reserves. Using these insects in a sustainable way by rural communities should address multiple factors, goals and conservation constraints. This study ranks tourist zones in Veracruz, México, to create and market butterfly-based handicrafts by applying a multicriteria analysis. We differentiated top zones where a segment of the rural population could benefit from this activity. Roads, butterfly diversity, and tourists emerge as key elements while protected areas and transport costs were considered as constraints. The economic value of the butterfly-based handicraft market was estimated as well.

the use of technogenic raw materials in the production of building composites is an urgent direction in the technology of production of building materials in view of its economic efficiency, environmental effect and wide possibilities of their application. Recently, the issues of environmental safety in the production of building materials, the possibility of their processing and disposal have come to the fore. All this is dictated by the need for energy and resource conservation, the massive depletion of natural reserves and the progres-sive pollution of the environment due to anthropogenic activities. Construction composites provide ample opportunities for recycling of secondary raw materials, as their structure allows them to be used not only as a filler, but also in some cases as additives for regulating certain properties. More studied and widely used are ash and slag mixtures on the basis of which various organomineral additives are developed. So, on the territory of the Chechen Republic there are dumps of ash and slag mixtures, which, according to their chem-ical and mineralogical composition, are suitable for the design of organomineral additives and fillers in con-struction concretes and solutions. Building solutions are widely used for interior and exterior finishing works during the construction of construction projects in the Chechen Republic, which is characterized by high humidity in the winter, which provokes deformations of the plaster layer on facades. In this article, the de-velopment of an organomineral additive based on an ash-slag mixture is considered to improve the quality of mortar mixtures resistant to such conditions.

Resumen: El rápido crecimiento de las carreras por montaña, ha motivado durante los últimos años su estudio. Aun son pocas las referencias bibliográficas que podemos encontrar a escala local, aunque algunas a nivel de España. Existen diferencias regionales, que demandan la necesidad de examinar este tipo de pruebas a una escala detallada. La Comunitat Valenciana, dada su extensión forestal y porcentaje de territorio montañoso (56 %), el número de espacios naturales (646) y superficie total protegida (40 %), se convierte en un buen ámbito de estudio. Una revisión bibliográfica y un análisis de la información recogida ha permitido determinar el número y la evolución de esta práctica en los últimos 25 años, la distribución espacial y temporal, y otras características de interés, como la tipología y los actores que intervienen.  La tendencia a realizar este tipo de actividades dentro de Espacios Naturales Protegidos, incita a conocer el alcance que reciben diferentes áreas protegidas, elegidas para el estudio, que vistos los resultados es bastante significativo. Surge entonces la necesidad de plantearse, si los métodos de gestión y regulación son adecuados. El objetivo no es prohibir las carreras por montaña, puesto que desde una perspectiva social y económica aportan muchos beneficios, sino hacer compatible su desarrollo con los valores de conservación y protección de los espacios naturales.   Palabras clave: Carreras por montaña, Comunidad Valenciana, Espacios Naturales Protegidos, Impacto ambiental.  Abstract: The fast increase of the mountain races events, has motivated recently the appearance of several studies. Still are few the available references at local scale, although some at Spanish level. There are regional differences that enhance the need of study that king of events in a local scale. The Comnunitat Valenciana, with large forested mountain areas (56 %), the number of natural reserves (646) and total protected proportion (40 %), becomes a good case of study. A literature review and an analysis of the collected information allowed to know the figures an evolution of the that practice during the last 25 years, its spatial and temporal distribution, among other relevant characteristics, like the kind of events and involved actors.  The tendency to organize that kind of events on Natural Protected Areas enhance the needs of evaluation of the affection to that areas, chosen for this paper, that seem clearly significative. The need arises then to consider whether the management and regulation methods are adequate. The objective is not to limit the mountain races, since from a social and economic perspective they provide many benefits, but to make their existence compatible with the protection and conservation of the natural areas.   Key words: Trail running, Valencia Autonomous Region, Natural protected areas, Environmental impact.

Abstract Current energy consumption and how to mitigate the negative environmental effects alongside rising demand have become prominent issues in everyday discourse. Following this trend, the topic of energy security too has stepped back into the spotlight. This article aims to analyse the energy security situation of three East Asian countries, Japan, South Korea, and Taiwan. All three countries feature similar predicaments, being overly reliant on imports, having minuscule natural reserves, and also being high-tech and service-based economies. In this article the author attempts to determine similarities and differences from an energy security perspective. In order to assess these countries, a framework is created with thirty-five distinct indicators relating to energy security. Each indicator is then systematically compared with each of the three countries. The results are then presented in a table and with graphs to illustrate a comparison of each country’s values. Through these results, the largest differences can be observed in energy efficiency and diversification of energy supply. The concluding remarks offer possible avenues for further studies and deliberate on lessons to be learned from these results.
