Article presents an overview of palaeogeographical heritage of the Permian Period in the network of protected areas and museums of the Perm Region. Permian Period, received its name after the city of Perm in Russia, includes the so-called “Main Permian Field”. It contains two types of palaeogeorgaphical heritage: marine and terrestrial. The representation of palaeogeographical objects of different types is analysed for the geoheritage of the protected areas in situ. Geoheritage ex situ, in the network of the regional museum collections, is estimated from the representative aspects. Recommendations on optimization of the protected areas network and museum acquisition is given from the point of view of paleo-geographical heritage objects representation.

The purpose of the research is to determine the level of conservation and management of signifi Permian System geoheritage objects in special protected natural areas and world museum collections as well as to rehabilitate and preserve Perm Region on the Permian museums and geoheritage map. Th geographical distribution of modern geotoponyms of the Permian geological System, identifi in 1841 in Russia and named aft the city of Perm, was made in relation to the stratigraphic (geochronological) scale subdivisions at the place of discovery by the level of system, series, stage (period, epoch, age respectively), including Global Boundary Stratotype Sections and Points (GSSP). Geographical distribution of the geoheritage sites allows highlighting their primary and secondary localization for the Permian Period. Signifi objects of the Permian heritage were analyzed in conjunction with its representation of the place of its discovery based on the protected areas and signifi museum collections network. Ex situ conservation of the Permian spatial collections' localization is caused by two main factor: territorial linkage to the localities (primary type research and acquisition), and acquisition of the most signifi collections by museums, universities and research institutes (secondary type of research and acquisition). Th analysis of signifi Permian geoheritage sites in the world spatial distribution allows us to identify nine main clusters. Key clusters of the Permian refer to CisUral region, South of the USA, and WestEastern China (with the GSSP for the Lower, Middle, and Upper Perm respectively). Signifi in situ sites let develop geotourism activities. Proposals for the Permian geoheritage system optimization in the Perm Region are formulated in conjunction with the network of protected areas, university research and key museum collections.

AbstractConservation programmes are always limited by available resources. Careful planning is therefore required to increase the efficiency of conservation and gap analysis can be used for this purpose. This method was used to assess the representativeness of current ex situ and in situ conservation actions of 234 priority crop wild relatives (CWR) in Indonesia. This analysis also included species distribution modelling, the creation of an ecogeographical land characterization map, and a complementarity analysis to identify priorities area for in situ conservation and for further collecting of ex situ conservation programmes. The results show that both current ex situ and in situ conservation actions are insufficient. Sixty-six percent of priority CWRs have no recorded ex situ collections. Eighty CWRs with ex situ collections are still under-represented in the national genebanks and 65 CWRs have no presence records within the existing protected area network although 60 are predicted to exist in several protected areas according to their potential distribution models. The complementarity analysis shows that a minimum of 61 complementary grid areas (complementary based on grid cells) are required to conserve all priority taxa and 40 complementary protected areas (complementary based on existing protected areas) are required to conserve those with known populations within the existing in situ protected area network. The top ten of complementary protected areas are proposed as the initial areas for the development of CWR genetic reserves network in Indonesia. It is recommended to enhanced coordination between ex situ and in situ conservation stakeholders for sustaining the long term conservation of CWR in Indonesia. Implementation of the research recommendations will provide for the first time an effective conservation planning of Indonesia’s CWR diversity and will significantly enhance the country’s food and nutritional security.

This work is focused on the diagnosis of behavior, from the point of view of control emissions and noise level, of a power Turbogas plant during the process of commissioning, to guarantee that its operation complies with national and international standards. The environmental diagnosis of the power plant was developed as part of the performance evaluation of the unit. The conditions of the unit evaluation include operation at base load and partial load, as well as time periods for load changes. The evaluated power plant consists of an aeroderivative gas turbine installed in a simple cycle, operating with a cooling system (chiller) installed in the urban zone of Mexico City. Therefore, it should comply with the legislation and regulations of the city concerning air pollution and allowed noise, besides the international standards established by the manufacturer. The study includes emissions measurements using a Continuous Emissions Monitoring System installed in-situ, previously calibrated and checked during and after the test which was found inside the permissible deviation of 3%. Measurements were recorded at intervals of 5 minutes during test periods of 110 minutes for each load and 45 minutes for load changes. On the other hand, noise pressure evaluation was carried out in near field as well as far field produced by the power plant during operation. Measurements were carried out by using precision instruments installed specifically for it. A temporary system for obtaining data was used to monitoring the environmental conditions every 30 seconds. It was possible to verify that the turbogenerator complies with all noise levels and contaminant emissions requirements and regulations according to the limits established by the manufacturer and national and international standards.

Industrial activities lead to the release of different types of toxic metals into the environment. Phytoremediation has been established as one of the environmental-friendly and economical processes that have the potential for the remediation of industrial waste. Phytoremediation is used to extract metals from industrial effluents using ex-situ and in-situ treatments. Also, phytoremediation may be used to reclaim the polluted land resource for agricultural purposes. Moreover, this also prevents the bioaccumulation and biomagnification of xenobiotics from farming activities if carried out from polluted land. Phyto-mining can be done to recover and reuse the heavy metals from plant tissues after phytoremediation by plants. This study aimed to give a comprehensive review of recent research work in heavy metal phytoremediation.

Biodiversity is vital for the stability of the planet; its ecosystem services provide essential elements for our survival and well-being. This review analyzes the national biodiversity policies and describes the main strategies for biodiversity conservation in Ecuador, one of the “mega-diverse” countries in the world with the highest species density. It deepens an analysis of in-situ and ex-situ conservation processes. Ecuador has six clear policies for biodiversity conservation. These policies strengthen biodiversity conservation through mechanisms that improve the well-being of wildlife by ensuring human, wildlife and ecosystem health. It promotes actions for the welfare of wildlife, through technical, administrative and legal tools. The National System of Protected Areas, with 60 protected areas, is the most effective in-situ conservation instrument at the country level. Several ex-situ conservation and management means for the conservation of wild species are being utilized, including nurseries, botanical gardens, zoos, germplasm banks, aquariums, species reproduction and rehabilitation centers. Ecuador is making slow progress on ex-situ conservation despite the availability of a sound policy framework, possibly due to financial, infrastructural, and/or technological challenges, and knowledge gaps. We propose fostering international research collaborations and establishing fully funded small-scale captive breeding programs at zoos, aquariums and university research facilities to help recovery of at-risk species of reptiles, amphibians, fish and species beyond Galapagos region. We recommend utilizing citizen science programs to fill the gaps of biodiversity information and increasing efforts to revive the ex-situ conservation strategies in protecting the unique biodiversity of Ecuador.

Studying the motivations and satisfaction of visitors in protected areas is increasingly important for the interaction with nature. The Samanes Park recreation area located in the city of Guayaquil in Ecuador is visited by national and international tourists for outdoor activities and for the purpose of being in contact with nature. The present empirical study was carried out in situ, for which univariate and bivariate techniques were applied using a questionnaire. The results show that the main motivations of the visit are "to enjoy its environment and pure air", "to enjoy its public recreation spaces", "to perform sports" and "to carry out activities in nature", which indicates the importance of ecotourism in this destination. The most valued attributes in satisfaction are "security", followed by "places of recreation". Visitors to the Samanes Park find general satisfaction in their visit and the vast majority are totally satisfied. All these findings show the importance of this site for ecotourism in Ecuador.

Gene conservation of native conifer species in British Columbia is considered necessary primarily to safeguard the future evolutionary potential of species to climate change, new biotic challenges and for commercial genetic improvement programs. The tactical options include: (i) maintaining existing protected areas, (ii) creating new reserves for in situ management, and (iii) ex situ collections of various types.A two-part strategy is presented, with emphasis on technical justifications, for the conservation of conifer tree genetic resources of 23 British Columbia species. Part I is a survey of the frequency of each species in current land reserves in BC. Part II outlines an approach that will aid in setting priorities for additional gene conservation activities for specific species. This process attempts to use information on: (i) levels of in situ protection, (ii) the status of each species in current provenance research and breeding programs, and (iii) the relative capabilities for natural regeneration for each species.Representation of the 23 native conifer species in the current network of protected areas is generally complete. For instance, western hemlock is under little threat, as extensive ex situ collections are in field tests; it is well protected in the current reserve network, and it has a great capacity for natural regeneration. At the other extreme, whitebark pine has no ex situ collections made to date, needs additional protection in some ecoregions of the province, and generally has poor natural regeneration potential. While implementation of our strategy will be an ongoing process (i.e. updating information from both new and old in situ reserves, and setting new priorities among species), several immediate issues have been noted. These include; (i) follow-up work in the area of population sampling for ex situ collections, (ii) "ground truthing" of current reserves where data are weak, and (iii) examining the merit of certain populations not located in BC (as they could be as important as those currently protected in BC).For the future, various broad management questions will need to be resolved, such as: (i) whether existing reserves will perpetuate the various gene pools, and what management will be appropriate for such areas, (ii) the impact of pollen migration from genetically improved production stands on reserve stands, and (iii) the role of commercially improved stands and the breeding populations themselves to meet gene conservation objectives.

The growth of interest in the Anthropocene has coincided with the rise of geoheritage research and these ideas seem to be mutually enriching. However, very few previous investigations were devoted to the Anthropocene geoheritage. The conceptual treatment of the geoheritage classification demonstrates that the majority of geoheritage types and forms are relevant to the Anthropocene. From types, the most relevant are the stratigraphical, economical and geomorphological types, which include, for instance, such unique objects as the Anthropocene global stratotype candidate sections, exploited ore deposits and man-made landforms, respectively. Ex-situ forms (such as museum collections) and many in-situ forms (such as quarries and roadcuts) result from the geological-scale activity of humans. The practical importance of the strong Anthropocene–geoheritage relationship is linked to communication of Anthropocene-related knowledge and better research coordination. Importantly, geosites and geopaks themselves manifest human influence on the global geological environment, that is, their establishment among the Anthropocene-related forces.

Under the unprecedented wave of urbanization and pace of economic development, the living conditions of residents have been unevenly changed in Chinese cities. To understand the diversified living conditions in Chinese urban neighborhoods from the supply-side point of view, new spatial and residential data were gathered to investigate the social infrastructure configurations around the residential communities. Using Tianjin as a case study, the research focuses on six important categories of human needs: education, healthcare, leisure, culture, entertainment, and transportation. Based on the cumulative accessibility measurements of 25 types of facilities, the social infrastructure configurations within neighborhoods are statistically and spatially analyzed and compared. The study discovered that: (1) despite the great diversity of living conditions in the city, the neighborhoods that have better services and strong associations with entertainment and education are prominent; (2) the neighborhoods with advantageous living conditions in different aspects tend to cluster at different places; (3) the neighborhoods of different types of communities, belonging to different administrative districts, or in different urban zones, all have distinctive characteristics in living conditions.

Risk Knowledge

The conservation of heritage structures is pivotal not only due to their cultural or historical importance for nations, but also for understanding their construction techniques as a lesson that can be applied to contemporary structures. Timber is considered to be the oldest organic construction material and is more vulnerable to environmental threats than nonorganic materials such as masonry bricks. In order to assess the structural vulnerability of heritage timber structures subjected to different types of risk, knowledge about their structural systems and configurations, the nature and properties of the materials, and the behavior of the structure when subjected to different risks, is essential for analysts. In order to facilitate the procedure, different assessment methods have been divided into the categories in situ and ex situ, which are applicable for vulnerability assessments at the element and full-scale level of a case study. An existing methodology for structural vulnerability assessments and conservation of heritage timber buildings is reviewed and a new methodology is proposed.
