Inundaciones y migración en la República Checa

Los residentes suelen centrar sus estrategias en protegerse de las inundaciones o adaptarse a ellas. La migración a gran escala desde las planicies aluviales de los ríos no se plantea, ni siquiera en las zonas de alto riesgo

Commuting patterns of Czech households exposed to flood risk

Using unique data collected from October to December 2012, we estimate the link between commuting to and from work and the level of household exposure to floods. The result suggests an empirical puzzle - individuals affected by only one flood are roughly 10% more likely to engage in the commuting activity, whereas households affected by two floods are 13% less likely to do so. We check the robustness of this result by operationalizing the past exposure to floods with variables that describe the geographical location of the house and its characteristics. We explain the puzzle by the fact that individuals commute to work in order to accumulate resources to decrease the household's vulnerability to flood risk, amongst other reasons. When the flood risk is high, some households out-migrate, and stayers commute less, probably, for similar reasons as why they stay. Further, we find evidence in support of the "network effect" hypothesis - an individual with an active commuter in the household is by 47% more likely to commence commuting. We also find that flood affected commuters travel shorter distance for work

Migration instead of Aid? Remittances and Brain Circulation as Tools of Development

International migration and development are among the most often cited issues in contemporary scholarly and political discussions. Reduction of socioeconomic disparities through development of economically less developed countries or liberalization of workforce movement are positioned very high on the political agendas of particular countries, as well as on those of supranational and international organizations. Therefore, it is not surprising that relations between migration and development attract more and more attention not only from the scientific community but from other individuals and organizations as well. In a limited amount of space, this paper uncovers the impacts of international migration, above all of the phenomenaons of remittances and skilled migration on the development of both receiving and sending countries. The article discusses the challenge of whether international migration is a better development strategy than traditional development tools such as Official Development Assistance (ODA) and argues against some traditional migration myths. This article wants to contribute to the discussion in the Czech Republic on relations between international migration and development with an emphasis on developing countries. The article is structured as follows. The first part is a brief description of international migration theories with development aspects in mind. The second part deals with international migration in the contemporary global world, stressing quantification of migration flows with respect to the level of development. Finally, the third chapter summarizes the most important findings from specific domains of relations between international migration and development (particularly remittances and skilled migration)

Direct Economic Impact Assessment of Winter Honeybee Colony Losses in Three European Countries

Honeybees are of great importance because of their role in pollination as well as for hive products. The population of managed colonies fluctuates over time, and recent monitoring reports show different levels of colony losses in many regions and countries. The cause of this kind of loss is a combination of various factors, such as the parasitic mite Varroa destructor, viruses, pesticides, management practices, climate change, and other stress factors. Having in mind that the economic aspect of honeybee colony losses has not been estimated, a pioneer effort was made for developing a methodology that estimates the economic impact of honeybee colony losses. Winter loss data was based on 2993 answers of the COLOSS standard questionnaire survey of honeybee winter colony losses for 2016/2017. In addition, market and financial data were used for each country. In a comparative analysis, an assessment on the economic impact of colony losses in Austria, Czechia, and Macedonia was made. The estimation considered the value of the colonies and the potential production losses of the lost colonies and of surviving but weak colonies. The direct economic impact of winter honeybee colony losses in 2016/2017 in Austria was estimated to be about 32 Mio; in Czechia, 21 Mio; and in Macedonia, 3 Mio. Economic impact reflects the different value levels in the three countries, national colony populations, and the magnitude of colony losses. This study also suggests that economic losses are much higher than the subsidies, which underlines the economic importance of honeybees for the agricultural sector

Climate Mobility and Development Cooperation

Development cooperation actors have been addressing climate change as a cross-cutting issue and investing in climate adaptation projects since the early 2000s. More recently, as concern has risen about the potential impacts of climate variability and change on human mobility, development cooperation actors have begun to design projects that intentionally address the drivers of migration, including climate impacts on livelihoods. However, to date, we know little about the development cooperation’s role and function in responding to climate related mobility and migration. As such, the main aim of this paper is to outline the policy frameworks and approaches shaping development cooperation actors’ engagement and to identify areas for further exploration and investment. First, we frame the concept of climate mobility and migration and discuss some applicable policy frameworks that govern the issue from various perspectives; secondly, we review the toolbox of approaches that development cooperation actors bring to climate mobility; and third, we discuss the implications of the current Covid-19 pandemic and identify avenues for the way forward. We conclude that ensuring safe and orderly mobility and the decent reception and long-term inclusion of migrants and displaced persons under conditions of more severe climate hazards, and in the context of rising nationalism and xenophobia, poses significant challenges. Integrated approaches across multiple policy sectors and levels of governance are needed. In addition to resources, development cooperation actors can bring data to help empower the most affected communities and regions and leverage their convening power to foster more coordinated approaches within and across countries

Who cares about ocean acidification in the Plasticene?

Plastics is all the rage, and mitigating marine litter is topping the agenda for nations pushing issues such as ocean acidification, or even climate change, away from the public consciousness. We are personally directly affected by plastics and charismatic megafauna is dying from it, and it is something that appears to be doable. So, who cares about the issue of ocean acidification anymore? We all should. The challenge is dual in the fact that is both invisible to the naked eye and therefore not felt like a pressing issue to the public, thereby not reaching the top of the agenda of policy makers; but also that it is framed in the climate change narrative of fear - whereby it instills in a fight-or-flight response in the public, resulting in their avoidance of the issue because they feel they are unable to take action that have results. In this article, we argue that the effective global environmental governance of ocean acidification, though critical to address, mitigate against and adapt to, is hindered by the both this lack of perception of urgency in the general public, fueled by a lack of media coverage, as well as a fight-or-flight response resulting from fear. We compare this to the more media friendly and plastics problem that is tangible and manageable. We report on a media plots of plastics and ocean acidification coverage over time and argue that the issue needs to be detangled from climate change and framed as its own issue to reach the agenda at a global level, making it manageable to assess and even care about for policy makers and the public alike?Agência financiadora European Cooperation in Science and Technology (COST) ITC Conference Grant within the COST Action OCEANGOV COST-ITCCG-CA15217-372 Horizon 2020 project GoJelly 774499 SINTEF Ocean project SEEINGSHORE NORTE-01-0145-FEDER-031893 NORTE 2020 Portugal 2020 European Union (EU) Portuguese Foundation for Science and Technology Portuguese Foundation for Science and Technology SFRH/BPD/108949/2015 CLIMFISH project n2/SAICT/2017 Horizon 2020 Framework Programme of the European Unioninfo:eu-repo/semantics/publishedVersio

Reduced local mutation density in regulatory DNA of cancer genomes is linked to DNA repair

Carcinogenesis and neoplastic progression are mediated by the accumulation of somatic mutations. Here we report that the local density of somatic mutations in cancer genomes is highly reduced specifically in accessible regulatory DNA defined by DNase I hypersensitive sites. This reduction is independent of any known factors influencing somatic mutation density and is observed in diverse cancer types, suggesting a general mechanism. By analyzing individual cancer genomes1, we show that the reduced local mutation density within regulatory DNA is linked to intact global genome repair machinery, with nearly complete abrogation of the hypomutation phenomenon in individual cancers that possess mutations in multiple nucleotide excision repair components. Together, our results connect chromatin structure, gene regulation and cancer-associated somatic mutation

Jejunal Variceal Bleeding Successfully Treated with Percutaneous Coil Embolization

A 52-yr-old male with alcoholic liver cirrhosis was hospitalized for hematochezia. He had undergone small-bowel resection due to trauma 15 yr previously. Esophagogastroduodenoscopy showed grade 1 esophageal varices without bleeding. No bleeding lesion was seen on colonoscopy, but capsule endoscopy showed suspicious bleeding from angiodysplasia in the small bowel. After 2 weeks of conservative treatment, the hematochezia stopped. However, 1 week later, the patient was re-admitted with hematochezia and a hemoglobin level of 5.5 g/dL. Capsule endoscopy was performed again and showed active bleeding in the mid-jejunum. Abdominal computed tomography revealed a varix in the jejunal branch of the superior mesenteric vein. A direct portogram performed via the transhepatic route showed portosystemic collaterals at the distal jejunum. The patient underwent coil embolization of the superior mesenteric vein just above the portosystemic collaterals and was subsequently discharged without re-bleeding. At 8 months after discharge, his condition has remained stable, without further bleeding episodes

Assessing uncertainties in climate change adaptation and land management

The entire cascade of scenario generation, global and regional climate modeling, as well as concrete measures towards climate adaptation are subject to uncertainties. An exact prediction of how the climate will change in the coming years, and how it will affect land use, is not possible. There is thus a perceived need to identify ways via which uncertainties can be addressed. Based on the need to address the research gap in this area, this paper reports the findings of a study on uncertainty in a climate change adaptation context, and how it is perceived. It consists of a multi-stakeholder survey among climate change professionals, including academic staff at universities, representatives from international agencies, members of NGOs, policymakers, and representatives of industry from 50 countries, including a balanced representation of industrialized and developing nations. The results obtained suggest that uncertainties are often a hindrance to engagement in climate change adaptation efforts, and to land management. Furthermore, there is a range of tools to reduce climate change adaptation uncertainties, whose deployment may help to address them. The paper concludes by providing a list of lessons learned and suggestions as to how uncertainty can be better communicated, and by doing so, how a reduction in the levels of climate change vulnerability may be achieved, and how land management may be fostered
