Human populations in the world's mountains: Spatio-temporal patterns and potential controls.

Changing climate and human demographics in the world's mountains will have increasingly profound environmental and societal consequences across all elevations. Quantifying current human populations in and near mountains is crucial to ensure that any interventions in these complex social-ecological systems are appropriately resourced, and that valuable ecosystems are effectively protected. However, comprehensive and reproducible analyses on this subject are lacking. Here, we develop and implement an open workflow to quantify the sensitivity of mountain population estimates over recent decades, both globally and for several sets of relevant reporting regions, to alternative input dataset combinations. Relationships between mean population density and several potential environmental covariates are also explored across elevational bands within individual mountain regions (i.e. "sub-mountain range scale"). Globally, mountain population estimates vary greatly-from 0.344 billion (31%) in 2015. A more detailed analysis using one of the population datasets (GHS-POP) revealed that in ∼35% of mountain sub-regions, population increased at least twofold over the 40-year period 1975-2015. The urban proportion of the total mountain population in 2015 ranged from 6% to 39%, depending on the combination of population and urban extent datasets used. At sub-mountain range scale, population density was found to be more strongly associated with climatic than with topographic and protected-area variables, and these relationships appear to have strengthened slightly over time. Such insights may contribute to improved predictions of future mountain population distributions under scenarios of future climatic and demographic change. Overall, our work emphasizes that irrespective of data choices, substantial human populations are likely to be directly affected by-and themselves affect-mountainous environmental and ecological change. It thereby further underlines the urgency with which the multitudinous challenges concerning the interactions between mountain climate and human societies under change must be tackled

Surgical site infection after cesarean section in Ukraine: results a multicenter study

The aim: To obtain the first national estimates of the current prevalence rate of SSI after CSEC and antimicrobial resistance of causing pathogens in Ukraine. Materials and methods: We performed a retrospective multhicentre cogort study based surveillance data was conducted from May 2017 to December 2019. The study population consisted of all women who had a cesarean section in 11 regional women hospitals of Ukraine. Definitions of SSI after cesarean section were used from the CDC/ NHSN. Results: A total of 2 326 CSEC operations and 14.7% SSI were identified within 30 days of the operation. Of these, 44.4% were superficial incisional SSI, 28.9% were deep incisional SSI, and 26.6% were organ/space SSI, 25.7% of which were classed as endometritis. Of all cases 70.5% of infections were detected post discharge. The most commonly identifed pathogen were Staphylococcus aureus (23.5%), Escherichiacoli (20%), Coagulase-negative staphylococci (8.1%), Enterococcus spp. (7.7%), Pseudomonasaeruginosa (7.7%), Enterobacter spp. (6.4%), and Streptococcus spp. (5.6%). The overall proportion of extended spectrum beta-lactamase (ESBL) production among Enterobacteriaceae was 18.3% and of methicillin-resistance in S. aureus(MRSA) 13.9%. Resistance to third-generation cephalosporins was observed in 15.2% E.coli and 7.9% Klebsiellapneumoniae isolates. Carbapenem resistance was identified in 7.3% of P.aeruginosa isolates. Conclusions: The results of this study revealed high rates of SSI after CSEC and most causing pathogens were associated with resistant to antibiotic stranis. This knowledge is essential to develop targeted strategies to surveillance and reduce the incidence of postoperative infections

Actions to halt biodiversity loss generally benefit the climate

The two most urgent and interlinked environmental challenges humanity faces are climate change and biodiversity loss. We are entering a pivotal decade for both the international biodiversity and climate change agendas with the sharpening of ambitious strategies and targets by the Convention on Biological Diversity and the United Nations Framework Convention on Climate Change. Within their respective Conventions, the biodiversity and climate interlinked challenges have largely been addressed separately. There is evidence that conservation actions that halt, slow or reverse biodiversity loss can simultaneously slow anthropogenic mediated climate change significantly. This review highlights conservation actions which have the largest potential for mitigation of climate change. We note that conservation actions have mainly synergistic benefits and few antagonistic trade-offs with climate change mitigation. Specifically, we identify direct co-benefits in 14 out of the 21 action targets of the draft post-2020 global biodiversity framework of the Convention on Biological Diversity, notwithstanding the many indirect links that can also support both biodiversity conservation and climate change mitigation. These relationships are context and scale-dependent; therefore, we showcase examples of local biodiversity conservation actions that can be incentivized, guided and prioritized by global objectives and targets. The close interlinkages between biodiversity, climate change mitigation, other nature\u27s contributions to people and good quality of life are seldom as integrated as they should be in management and policy. This review aims to re-emphasize the vital relationships between biodiversity conservation actions and climate change mitigation in a timely manner, in support to major Conferences of Parties that are about to negotiate strategic frameworks and international goals for the decades to come

Technical summary

Human interference with the climate system is occurring. Climate change poses risks for human and natural systems. The assessment of impacts, adaptation, and vulnerability in the Working Group II contribution to the IPCC's Fifth Assessment Report (WGII AR5) evaluates how patterns of risks and potential benefits are shifting due to climate change and how risks can be reduced through mitigation and adaptation. It recognizes that risks of climate change will vary across regions and populations, through space and time, dependent on myriad factors including the extent of mitigation and adaptation
