These countries, located in regions prone to unpredictable temperature and precipitation changes, are facing significant challenges, particularly in climate-sensitive sectors such as mining and agriculture. LDCs need more resilience to adverse climate shocks but have limited capacity for adaptation compared to other developed and developing nations. This paper examines Liberia’s susceptibility to climate change as a least developed country, focusing on its exposure, sensitivity, and adaptive capacity. It provides an overview of LDCs and outlines the global distribution of carbon dioxide emissions. The paper also evaluates specific challenges that amplify Liberia’s vulnerability and constrain sustainable adaptation, providing insight into climate change’s existing and potential effects. The paper emphasizes the urgency of addressing climate impacts on Liberia and calls for concerted local and international efforts for effective and sustainable mitigation efforts. It provides recommendations for policy decisions and calls for further research on climate change mitigation and adaptation.展开更多

Design/methodology/approach: In this study we reconstruct the framework of the 2010 and 2018 models of book evaluation in Poland within the performance-based research funding system. Findings: For almost 20 years the book evaluation system in Poland has been based on the verification of various technical criteria(e.g. length of the book). The new 2018 model is based on the principle of prestige inheritance(a book is worth as much as its publisher is) and is inspired by the publisher list used in the Norwegian Model. In this paper, we argue that this solution may be a more balanced policy instrument than the previous 2010 model in which neither the quality of the publisher nor the quality of the book played any role in the evaluation.Research limitations: We work from the framework of the 2018 model of book evaluation specified in the law on higher education and science from 20 July 2018, as implementation acts are not available yet. Practical implications: This study may provide a valuable point of reference on how structural reforms in the research evaluation model were implemented on a country level. The results of this study may be interesting to policy makers, stakeholders and researchers focused on science policy. Originality/value: This is the very first study that presents the new framework of the Polish research evaluation model and policy instruments for scholarly book evaluation. We describe what motivated policy makers to change the book evaluation model, and what arguments were explicitly raised to argue for the new solution.展开更多

On the basis of 236 samples whose ages are determined by 14C chronological method and their sites are corrected with ancient water depth and crustal deformation, a basic model about sea-level changes of the South China coast since late Epipleistocene is set up. This model basically accords with the general cognitions of predecessors, i. e. it not only represents the common characteristics of sea-level changes of the East China coast but has some features of the South China coast itself. In general, this model is relatively close to the Fairbridge's curve, indicating that the sea-level undulations exist since 6 ka ago but the ranges of undulations are slightly larger than those of Fairbridge's curve.展开更多

Research in vegetables has been historically key. From early domestication efforts to modern-day breeding and value addition, research has enabled vegetable productivity to support the nutritional and economic needs of societies. Impactful research, however, requires competent research capacity and a guiding framework, in a continuously changing socio-climatic world. Vegetable research appraisal in Malawi, especially regarding capacity, focus, and a guiding framework, is lacking. By using 5 search engines and 506 analyzed publications, this review sought to first examine the existing research capacity in Malawi and assess the vegetable research focus in terms of both value chain analysis themes and specific vegetable tax. This approach allowed for the isolation and flagging out of key emerging issues from existing research that positively contextualize future vegetable research direction in Malawi. It has been found that Malawi has adequate institutional and expertise capacity to further vegetable research. The identified challenges include local funding and infrastructural capacity to leverage donor funding. Three key emerging issues of climate change, modeling, and biofortification in vegetable crops have been identified. It is suggested that, with Malawi facing the climate change challenge, research focus in these areas, will enhance not only nutritional and economic security, but also overall climate change readiness. Key to climate change readiness is the involvement of indigenous vegetable production. As a package, vegetable cultivation can play a critical role in contributing to the achievement of pillar 1 of the Malawi vision 2063, which seeks to leverage agricultural productivity and commercialization with a focus on climate change resilience.展开更多

National perspectives play a crucial role in addressing climate change. Mutual understanding of perspectives is nec- essary to result in rational policies and a consensus among stakeholders with divergent interests. Conceptual frameworks for understanding the problem of climate change in China, the largest developing country and the largest greenhouse gas emitter, are of great significance to national and international efforts to address the problems of climate change. Chinese perceptions of climate change as a sustainable development problem have recently been in tension with an emerging Western perspective that frames climate change as a security issue. This paper explores Chinese perceptions of climate change as expressed in recent governmental policy statements, public opinion surveys, and academic scholarship with a focus on publications in Chinese-language journals, often unfamiliar in the West. It looks at the relationship between Chinese research and policy and finds that the Chinese policy frame of climate change as a sustainable development problem draws from the body of domestic research and is reflective of the perspectives and multidisciplinary approach of Chinese researchers in areas of climate change.展开更多

The paper summarizes the fast growth of OA journals and OA repositories, the outstanding OA journal impact increase, the rise of mega-OA journals like PLoS ONE, the overwhelming support of research communities to open access of publicly funded research, and the quick building up of OA support structures. These forces work together to push scholarly communications toward a turning point where OA resources occupy a major and increasing share of scholarly research resources and when management of OA resources becomes a strategic, yet unfamiliar, and potentially disruptive task for research libraries. This paper is composed of two parts. The first part will focus on the development of OA resources, while the second part will analyze the challenges in management of OA resources and develop an OA resource strategy exemplified by some of NSL's initiatives.展开更多

NERRS is an ecosystem-based research and monitoring network of sites serving as platforms to develop quantitative databases of value to coastal management programs in identifying and tracking short-term variability and long-term changes in the integrity and biodiversity of estuarine systems nationwide due to natural perturbations and anthropogenic disturbances. The reserve sites also play a vital role in assessing coastal issues of local, regional, and national significance for the purpose of sustaining estuarine systems and coastal lands, such as evaluating their responses to climate change and other major stressors to inform coastal decision-making and public awareness for the protection and resilience of natural resources and coastal communities. Over the past four decades, NERRS sites have collected large volumes of research and monitoring data of great utility in characterizing estuarine environments and addressing an array of resource-management concerns, including degraded water quality, loss and alteration of essential habitat, impacted fisheries, invasive species, and conservation.展开更多

The Nile Delta ...Availability of reliable knowledge on future climate change impacts, vulnerability, and adaptation are considered key elements to improving adaptive capacities and developing proper adaptation actions. The Nile Delta vulnerability to Sea Level Rise (SLR) has been the subject of a relatively significant number of studies in Egypt. The research question that this paper intends to address is “to what extent have the produced scientific knowledge supported climate change adaptation policy making, concerning inundation by SLR in the Nile Delta”. To address this question, the paper begins with a review of the literature on policy-research interaction, based on which a framework of policy-research interactions is developed. This is followed by examining generated knowledge from research and the role of such knowledge on adaptation strategy development in Egypt. It was found that the research cycle has provided ample knowledge on the Nile Delta vulnerability to inundation by SLR. Additionally, the bulk of this research work and produced knowledge have been the main source of information for climate change adaptation policymaking. The interaction between research and policymaking interest in the climate change adaptation arena in Egypt confronted several challenges that may have reduced impacts of research on policymaking. These challenges included low interest in the far future, uncertain sea level rise impacts among policymakers and the uncoordinated research and varied estimates of sea level rise impacts provided by the research cycle. Moreover, the lack of proper and effective communication channels between the two cycles may have further hindered possible interaction.展开更多

This paper, the progress in scientific investigations and research regarding the atmosphere in the polar regions over the last 30 years by Chinese scientists is summarized. Primary understanding of the relationship between the polar regions and global change, especially, the variations in time and space in the Antarctic and Arctic regions with respect to climate change is indicated. Operational weather forecasts for investigation of the polar regions have also been established. Moreover, changes in sea ice and their impact on the atmosphere of polar regions have been diagnosed and simulated. Parameterization of the atmospheric boundary layer of different underlying layers and changes in the atmospheric ozone in the polar region has also been experimented. Overall, there has been great progress in studies of the possible impact of changes in the atmospheric environment of polar regions on circulation in East Asia and the climate of China.展开更多

On the basis of 236 samples whose ages are determined by 14C chronological method and their sites are corrected with ancient water depth and crustal deformation, a basic model about sea-level changes of the South China coast since late Epipleistocene is set up. This model basically accords with the general cognitions of predecessors, i. e. it not only represents the common characteristics of sea-level changes of the East China coast but has some features of the South China coast itself.

文摘Vapor pressure deficit(VPD)plays a crucial role in determining plant physiological functions and exerts a substantial influence on vegetation,second only to carbon dioxide(CO_(2)).As a robust indicator of atmospheric water demand,VPD has implications for global water resources,and its significance extends to the structure and functioning of ecosystems.However,the influence of VPD on vegetation growth under climate change remains unclear in China.This study employed empirical equations to estimate the VPD in China from 2000 to 2020 based on meteorological reanalysis data of the Climatic Research Unit(CRU)Time-Series version 4.06(TS4.06)and European Centre for Medium-Range Weather Forecasts(ECMWF)Reanalysis 5(ERA-5).Vegetation growth status was characterized using three vegetation indices,namely gross primary productivity(GPP),leaf area index(LAI),and near-infrared reflectance of vegetation(NIRv).The spatiotemporal dynamics of VPD and vegetation indices were analyzed using the Theil-Sen median trend analysis and Mann-Kendall test.Furthermore,the influence of VPD on vegetation growth and its relative contribution were assessed using a multiple linear regression model.The results indicated an overall negative correlation between VPD and vegetation indices.Three VPD intervals for the correlations between VPD and vegetation indices were identified:a significant positive correlation at VPD below 4.820 hPa,a significant negative correlation at VPD within 4.820–9.000 hPa,and a notable weakening of negative correlation at VPD above 9.000 hPa.VPD exhibited a pronounced negative impact on vegetation growth,surpassing those of temperature,precipitation,and solar radiation in absolute magnitude.CO_(2) contributed most positively to vegetation growth,with VPD offsetting approximately 30.00%of the positive effect of CO_(2).As the rise of VPD decelerated,its relative contribution to vegetation growth diminished.Additionally,the intensification of spatial variations in temperature and precipitation accentuated the spatial heterogeneity in the impact of VPD on vegetation growth in China.This research provides a theoretical foundation for addressing climate change in China,especially regarding the challenges posed by increasing VPD.

文摘Global climate change has evolved from a scientific problem into an economic and political problem oI worlOwloe rater- est. National perspectives play a crucial role in addressing climate change. Mutual understanding of perspectives is nec- essary to result in rational policies and a consensus among stakeholders with divergent interests. Conceptual frameworks for understanding the problem of climate change in China, the largest developing country and the largest greenhouse gas emitter, are of great significance to national and international efforts to address the problems of climate change. Chinese perceptions of climate change as a sustainable development problem have recently been in tension with an emerging Western perspective that frames climate change as a security issue. This paper explores Chinese perceptions of climate change as expressed in recent governmental policy statements, public opinion surveys, and academic scholarship with a focus on publications in Chinese-language journals, often unfamiliar in the West. It looks at the relationship between Chinese research and policy and finds that the Chinese policy frame of climate change as a sustainable development problem draws from the body of domestic research and is reflective of the perspectives and multidisciplinary approach of Chinese researchers in areas of climate change.

文摘Open access(OA) resources are becoming a main part of scholarly information. The paper summarizes the fast growth of OA journals and OA repositories, the outstanding OA journal impact increase, the rise of mega-OA journals like PLoS ONE, the overwhelming support of research communities to open access of publicly funded research, and the quick building up of OA support structures. These forces work together to push scholarly communications toward a turning point where OA resources occupy a major and increasing share of scholarly research resources and when management of OA resources becomes a strategic, yet unfamiliar, and potentially disruptive task for research libraries. This paper is composed of two parts. The first part will focus on the development of OA resources, while the second part will analyze the challenges in management of OA resources and develop an OA resource strategy exemplified by some of NSL's initiatives.
文摘The National Estuarine Research Reserve System (NERRS) is an integrated network of 29 protected and coordinated estuarine reserve sites in 23 states and one territory (Puerto Rico) covering more than 525,000 ha of estuarine habitat, adjoining wetlands, and uplands that encompass 19 biogeographical regions along the Atlantic, Gulf of Mexico, and Pacific coasts, as well as the Caribbean Sea and Great Lakes. NERRS is an ecosystem-based research and monitoring network of sites serving as platforms to develop quantitative databases of value to coastal management programs in identifying and tracking short-term variability and long-term changes in the integrity and biodiversity of estuarine systems nationwide due to natural perturbations and anthropogenic disturbances. The reserve sites also play a vital role in assessing coastal issues of local, regional, and national significance for the purpose of sustaining estuarine systems and coastal lands, such as evaluating their responses to climate change and other major stressors to inform coastal decision-making and public awareness for the protection and resilience of natural resources and coastal communities. Over the past four decades, NERRS sites have collected large volumes of research and monitoring data of great utility in characterizing estuarine environments and addressing an array of resource-management concerns, including degraded water quality, loss and alteration of essential habitat, impacted fisheries, invasive species, and conservation.

文摘Availability of reliable knowledge on future climate change impacts, vulnerability, and adaptation are considered key elements to improving adaptive capacities and developing proper adaptation actions. The Nile Delta vulnerability to Sea Level Rise (SLR) has been the subject of a relatively significant number of studies in Egypt. The research question that this paper intends to address is “to what extent have the produced scientific knowledge supported climate change adaptation policy making, concerning inundation by SLR in the Nile Delta”. To address this question, the paper begins with a review of the literature on policy-research interaction, based on which a framework of policy-research interactions is developed. This is followed by examining generated knowledge from research and the role of such knowledge on adaptation strategy development in Egypt. It was found that the research cycle has provided ample knowledge on the Nile Delta vulnerability to inundation by SLR. Additionally, the bulk of this research work and produced knowledge have been the main source of information for climate change adaptation policymaking. The interaction between research and policymaking interest in the climate change adaptation arena in Egypt confronted several challenges that may have reduced impacts of research on policymaking. These challenges included low interest in the far future, uncertain sea level rise impacts among policymakers and the uncoordinated research and varied estimates of sea level rise impacts provided by the research cycle. Moreover, the lack of proper and effective communication channels between the two cycles may have further hindered possible interaction.

文摘The Antarctic and Arctic are sensitive to global climate change; therefore, they are key regions of global climate change research. This paper, the progress in scientific investigations and research regarding the atmosphere in the polar regions over the last 30 years by Chinese scientists is summarized. Primary understanding of the relationship between the polar regions and global change, especially, the variations in time and space in the Antarctic and Arctic regions with respect to climate change is indicated. Operational weather forecasts for investigation of the polar regions have also been established. Moreover, changes in sea ice and their impact on the atmosphere of polar regions have been diagnosed and simulated. Parameterization of the atmospheric boundary layer of different underlying layers and changes in the atmospheric ozone in the polar region has also been experimented. Overall, there has been great progress in studies of the possible impact of changes in the atmospheric environment of polar regions on circulation in East Asia and the climate of China.
