Environmental Change and Human Mobility: Trends, Law and Policy

"Enhancing the protection of persons displaced by natural disasters and the impacts of climate change will require sustained attention. This article identifies practical solutions, many of which are currently under consideration by governments and international organizations, to improve the lives of millions of people affected by environmental crises. It begins with a brief overview of why people move, the nature of those movements, and the relationship between human mobility and adaptation to environmental change by highlighting three types of mobility – migration, displacement and planned relocation. Next, the international and regional level will be discussed, with particular focus on legislative and policy frameworks for addressing human mobility in the context of environmental change. The article identifies gaps in existing frameworks as well as recent efforts to address them, particularly through mini-multilateral initiatives aimed at identifying principles and practices that should guide governmental action. The article concludes that efforts to improve responses require a better evidence base than currently exists on issues such as the environmental determinants of migration, displacement and planned relocation; the multi-faceted ways in which environmental factors relate to the many other causes of population movements in the cases of human mobility; and the impact of such movements on the well-being of migrants, communities of origin, and communities of destination."

US Leadership and the International Refugee Regime

This article examines the role of the United States in the international refugee regime. It argues that the United States generally leads in assistance and protection of refugees and displaced persons when three conditions are present: a strong link to US foreign policy; clear and highly visible humanitarian needs and important domestic constituencies in support of action; and strong congressional support. The United States manifests its leadership through its financial contributions, as the largest donor to the array of international organizations with responsibilities in this area; resettlement of the refugees; and the use of the convening power of the US government. Nevertheless, there are reasons to be cautious about US leadership. While it is unlikely that the United States will soon lose its status as principal donor and principal strategist on tackling displacement, its ability to generate new resettlement offers is less clear, as is its ability to increase its own resettlement levels. The asylum system still has significant gaps, making it difficult for the United States to lead by example.Cet article examine le rôle que jouent les États-Unis (É.-U.) vis-à-vis du régime international des réfugiés. Il défend l’idée que les États-Unis jouent généralement un rôle de leader actif en matière d’assistance et de protection apportées aux réfugiés et aux personnes déplacées quand trois conditions sont remplies: l’existence d’un lien solide avec la politique étrangère des É.-U., un solide soutien du Congrès, et la coexistence de besoins humanitaires manifestes et particulièrement visibles et d’importantes parties prenantes nationales pour soutenir leur action. En tant que principal donateur des organismes internationaux responsables dans ce domaine, les É.-U. expriment leur leadership par leurs contributions financières, mais aussi en réinstallant les réfugiés et en faisant appel au pouvoir de mobilisation de leur gouvernement. Il existe néanmoins des raisons d’être vigilant vis-à-vis de leur leadership. Même s’il est peu probable qu’ils perdent dans un avenir proche leur statut de principal donateur et leur place parmi les principaux stratèges de la problématique des déplacements, leur capacité à offrir de nouveaux sites de réinstallation est moins évidente que celle de développer leurs propres sites. Le régime d’asile comporte encore d’importantes lacunes, qui rendent difficiles pour les É.-U. de diriger par l’exemple

The effect of age on neural processing of pleasant soft touch stimuli

Tactile interactions with our environment stimulate afferent fibers within the skin, which deliver information about sensations of pain, texture, itch and other feelings to the brain as a comprehensive sense of self. These tactile interactions can stimulate brain regions involved in interoception and reward processing. This study examined subjective, behavioral, and neural processing as a function of age during stimulation of A-beta (Aβ) and C tactile (CT) afferents using a soft brush stroke task. 16 adolescents (ages 15–17), 22 young adults (ages 20–28), and 20 mature adults (ages 29–55) underwent a simple continuous performance task while periodically anticipating and experiencing a soft touch to the palm or forearm, during functional magnetic resonance imaging (fMRI). fMRI results showed that adolescents displayed greater bilateral posterior insula activation than young and mature adults across all conditions and stimulus types. Adolescents also demonstrated greater bilateral posterior insula activation than young and mature adults specifically in response to the soft touch condition. Adolescents also exhibited greater activation than mature adults in bilateral inferior frontal gyrus and striatum during the soft touch condition. However, mature adults showed greater striatum activation than adolescents and young adults during anticipation. In the left anterior cingulate cortex, mature adults exhibited greater activation than adolescents and young adults when anticipating the upcoming touch. These results support the hypothesis that adolescents show an exaggerated neural response to pleasant stimulation of afferents, which may have profound effects on how they approach or avoid social and risky situations. In particular, heightened interoceptive reactivity to pleasant stimuli might cause adolescents to seek experiences that are associated with pleasant stimulation

Collaborative Learning and Innovative Assessment in Humanitarian Studies

This article examines a multiyear project funded by the Teagle Foundation to assess student learning in humanitarian studies. It explores outcomes derived from developing a collaborative learning approach to humanitarian action that emphasizes both cross-campus and cross-institutional peer-to-peer learning and exchange. Faculty, staff, and students from Fairfield, Fordham, and Georgetown Universities worked together as members of the Jesuit Universities Humanitarian Action Network (JUHAN) to design an innovative and comprehensive assessment process for curricular programs in humanitarian studies, as well as courses with significant humanitarian content. In particular, we focus on the value of establishing cognitive and affective learning objectives; developing tools and methods to assess learning (for example, rubrics and vignettes); demonstrating use of these tools through piloting and data analysis; and closing the assessment “loop.” As the first of its kind assessment strategy for humanitarian studies at the undergraduate level, we argue that these efforts make important inroads in establishing a common baseline for measuring learning in the burgeoning field of humanitarian studies. They also contribute to preparing individuals for futures in the humanitarian profession and to becoming “men and women for and with others.”

Remittance flows to post-conflict states: perspectives on human security and development

This repository item contains a single issue of the Pardee Center Task Force Reports, a publication series that began publishing in 2009 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future.Migrant remittances – that is, money or other goods sent to relatives in the country of origin– play an increasingly central role in post-conflict reconstruction and national development of conflict-affected states. Private remittances are of central importance for restoring stability and enhancing human security in post-conflict countries. Yet the dynamics of conflict-induced remittance flows and the possibilities of leveraging remittances for post-conflict development have been sparsely researched to date. This Pardee Center Task Force Report is the outcome of an interdisciplinary research project organized by the Boston University Center for Finance, Law & Policy, in collaboration with The Frederick S. Pardee Center for the Study of the Longer-Range Future. The Task Force was convened by Boston University development economist John R. Harris and international banking expert Donald F. Terry, and social anthropologist Daivi Rodima-Taylor, Visiting Researcher at the Boston University African Studies Center, served as lead researcher and editor for the report. The Task Force was asked to research, analyze, and propose policy recommendations regarding the role of remittances in post-conflict environments and their potential to serve as a major source of development funds. The report’s authors collectively suggest a broader approach to remittance institutions that provides flexibility to adapt to specific local practices and to make broader institutional connections in an era of growing population displacement and expanding human and capital flows. Conditions for more productive use of migrants’ remittances are analyzed while drawing upon case studies from post-conflict countries in Africa, Asia and Latin America. The papers in this Task Force Report establish the importance of remittances for sustaining local livelihoods as well as rehabilitating institutional infrastructures and improving financial inclusion in post-conflict environments. Highlighting the increasing complexity of global remittance systems, the report examines the growing informality of conflict-induced remittance flows and explores solutions for more efficient linkages between financial institutions of different scales and degrees of formality. It discusses challenges to regulating international remittance transfers in the context of growing concerns about transparency, and documents the increasing role of diaspora networks and migrant associations in post-conflict co-development initiatives. The Task Force Report authors outline the main challenges to leveraging remittances for post-conflict development and make recommendations for further research and policy applications

Wildlife Trade and Human Health in Lao PDR: An Assessment of the Zoonotic Disease Risk in Markets.

Although the majority of emerging infectious diseases can be linked to wildlife sources, most pathogen spillover events to people could likely be avoided if transmission was better understood and practices adjusted to mitigate risk. Wildlife trade can facilitate zoonotic disease transmission and represents a threat to human health and economies in Asia, highlighted by the 2003 SARS coronavirus outbreak, where a Chinese wildlife market facilitated pathogen transmission. Additionally, wildlife trade poses a serious threat to biodiversity. Therefore, the combined impacts of Asian wildlife trade, sometimes termed bush meat trade, on public health and biodiversity need assessing. From 2010 to 2013, observational data were collected in Lao PDR from markets selling wildlife, including information on volume, form, species and price of wildlife; market biosafety and visitor origin. The potential for traded wildlife to host zoonotic diseases that pose a serious threat to human health was then evaluated at seven markets identified as having high volumes of trade. At the seven markets, during 21 observational surveys, 1,937 alive or fresh dead mammals (approximately 1,009 kg) were observed for sale, including mammals from 12 taxonomic families previously documented to be capable of hosting 36 zoonotic pathogens. In these seven markets, the combination of high wildlife volumes, high risk taxa for zoonoses and poor biosafety increases the potential for pathogen presence and transmission. To examine the potential conservation impact of trade in markets, we assessed the status of 33,752 animals observed during 375 visits to 93 markets, under the Lao PDR Wildlife and Aquatic Law. We observed 6,452 animals listed by Lao PDR as near extinct or threatened with extinction. The combined risks of wildlife trade in Lao PDR to human health and biodiversity highlight the need for a multi-sector approach to effectively protect public health, economic interests and biodiversity

Xyloglucan is released by plants and promotes soil particle aggregation

Soil is a crucial component of the biosphere and is a major sink for organic carbon. Plant roots are known to release a wide range of carbon-based compounds into soils, including polysaccharides, but the functions of these are not known in detail. Using a monoclonal antibody to plant cell wall xyloglucan, we show that this polysaccharide is secreted by a wide range of angiosperm roots, and relatively abundantly by grasses. It is also released from the rhizoids of liverworts, the earliest diverging lineage of land plants. Using analysis of water-stable aggregate size, dry dispersion particle analysis and scanning electron microscopy, we show that xyloglucan is effective in increasing soil particle aggregation, a key factor in the formation and function of healthy soils. To study the possible roles of xyloglucan in the formation of soils, we analysed the xyloglucan contents of mineral soils of known age exposed upon the retreat of glaciers. These glacial forefield soils had significantly higher xyloglucan contents than detected in a UK grassland soil. We propose that xyloglucan released from plant rhizoids/roots is an effective soil particle aggregator and may, in this role, have been important in the initial colonization of land
