Flexible pavement design requires considering a variety of factors including the materials used, variations in water tables, traffic levels, and the climatic conditions the road will experience over its lifetime. Most pavement designs are based on historical climate variables such as temperature and precipitation that are already changing across much of the United States, and do not reflect projected trends. As pavements are typically designed to last 20 years or more, designs that do not account for current and future trends can result in reduced performance. However, incorporating climate projections into pavement design is not a trivial exercise. Significant mismatches in both spatial and temporal scale challenge the integration of the latest global climate model simulations into pavement models. This study provides a national-level overview of what the impact of climate change to flexible pavement could look like, and where regional focus should be placed. It also demonstrates a new approach to developing high-resolution spatial and temporal projections that generates hourly information at the scale of individual weather stations, and applies this as input to the AASHTOWare Pavement ME Design™ model. The impact of three different future climates on pavement performance and time to reach failure thresholds in 24 locations across the United States are quantified. Changes to projected pavement performance differ by location, but nearly all result in decreased performance under current design standards. The largest increases in distress are observed for permanent deformation measures, especially toward the end of the century under greater increases in temperature.

Do negative shocks in origin countries encourage or inhibit international migration? What roles do networks play in modifying out-migration responses? The answers to these questions are not theoretically obvious, and past empirical findings are equivocal. We examine the impact of hurricanes on a quarter century of international migration to the United States. Hurricanes increase migration to the United States, with the effect’s magnitude increasing in the size of prior migrant stocks. We provide new insights into how networks facilitate legal, permanent US immigration in response to origin country shocks, a matter of growing importance as climate change increases natural disaster impacts.

The disparate fates of the polluter pays principle (ppp) as an instrument of municipal environmental governance in the environmental law of China, India, and the United States illustrate how institutions and culture can shape its use. In China, essential elements of the Chinese legal tradition and an institutionalized devolution of power from the central government to local governments essentially neutralized the Chinese variant of the ppp in one important context by mobilizing certain culturally defined behavioural norms at the local level. In India, the Supreme Court has behaved in accordance with the socially revolutionary role intended for it by the framers of India’s Constitution by recognizing a maximalist conception of the ppp as part of Indian law, although other features of India’s unique legal culture and institutions have reduced the impact of this development. In the United States, the institutionalized fragmentation of the law-making process within the Federal Government has undermined even the implicit implementation of the ppp, to which US environmental statutes do not refer. The implications of these developments for the ppp as an instrument of municipal but also global environmental governance in climate change mitigation law flow less from the nominal status of the ppp in the laws of China, India, and the United States than from the unique institutional and cultural conditions that prevail there. The result is a case study in how institutions and culture can transform the implementation of a principle of environmental governance that at first glance might seem to be a simple exercise in economic rationality into a different exercise that is not simple at all.

<p>Groundwater represents 98% of the world's freshwater resource. This resource is strongly impacted by the increase in temperature and variation in precipitation. Therefore, the relationship between climate change and the dynamics of aquifer recharge is still poorly understood. It was not until the 1980s when investigations in this field were improved. This research aims to evaluate the studies carried out on the impact of climate change-related to the recharge of aquifers. The applied methodology is strictly based on the bibliographic review. Bibliographic references were selected from citation database Scopus. This database was studied from a quantitative analysis using the Bibliometric package in RStudio. This investigation evaluates growth performance research on aquifer recharge on climate change from the 1980s to 2020.</p><p> </p><p>The results show an average growth of 14.38% and a significant increase in research from 2009. This study identifies 52 countries, just over 26% of total countries; the highest contribution has been made by Australia, the United States and Spain. The journals with the most increased contributions are Water Journal, Journal of Hydrology, Water Resources Research, Science of the Total Environment, and Hydrology and Earth System Sciences. According to the impact of climate change, the worst projections related to the decrease in recharge were identified in arid and desert areas. While the highest recharges were placed in the northern regions and at high altitudes where the recharge capacity is maintained or increases due to rapid thaw and increasing rain. More studies should be extended to analyse groundwater assessment in other latitudes to achieve a complete and comprehensive understanding. This understanding should be one of the priorities of water and governments' scientific society to safeguard this precious resource.</p><p><strong>Key words: </strong>Climate change, aquifer recharge, climate models, precipitation, and temperature.</p>
