    Content: With international production fragmentation, countries specialize in activities along the production chain rather than particular products. This paper therefore analyzes export diversification taking an activity perspective. It measures export activities combining new data on the export income of workers in industries cross classified by occupational classes. Based on the panel data, the paper documents that countries initially specialize along the extensive margin (shifting activities across industries) but later on along the intensive margin (shifting activities across occupational classes). New activity specialization is found to be strongly related to the proximity of this activity to the initial export basket. Yet, countries that defy proximity appear to grow faster. The results show that an activity perspective delivers novel insights into trade development and structural change.

    Content: As climate change intensifies, dry rainfall shocks and droughts are a growing concern. At the same time, scientific evidence suggests that the world has surpassed the safe planetary boundary for green water, which is water stored in biomass and soil that is crucial for maintaining climate resilience. Yet, evidence at the global scale of these combined forces on economic growth is poorly understood. This paper attempts to fill this gap by using data on annual subnational gross domestic product for 82 countries from 1990-2014. Using rainfall shocks as plausibly exogenous variations in a spatially specific panel at the grid level, the analysis finds that the global effects of droughts on economic activity are substantial. Moderate to extreme droughts reduce gross domestic product per capita growth between 0.39 and 0.85 percentage point, on average, depending on the level of development and baseline climatic conditions, with low- and middle-income countries in arid areas sustaining the highest relative losses. In high-income countries, moderate droughts have no impact, and only extreme droughts have adverse effects, reducing growth by about 0.3 percentage point, a little less than half the impact felt in the low- and middle-income country sample for the same intensity of drought. Crucially, the impact of a dry shock of a given magnitude also depends on antecedent green water availability. The results show that increases in soil moisture in previous years can neutralize the harmful impacts from a dry shock, with suggestive evidence that local and upstream forest cover are key channels through which these impacts manifest. These findings have important implications for measuring the economic impact of droughts and can inform adaptation investments

    Content: The fallout of nitrogen pollution is considered one of the largest global externalities facing the world, impacting air, water, soil, and human health. This paper combines data from the Demographic and Health Survey data set across India, Vietnam, and 33 African countries to analyze the causal links between pollution exposure experienced during the very earliest stages of life and later-life health. The results show that pollution exposure experienced in the critical years of development-from birth until age three-is associated with decreased height as an adult, a well-known indicator of overall health and productivity, and is robust to several statistical checks. Because adult height is related to education, labor productivity, and income, this also implies a loss of earning potential. The analysis begins within an assessment in India, where the data are more available, and is then extended to geographic settings including Vietnam and 33 countries in Africa. The results are consistent and show that early-life exposure to nitrogen pollution in water can lower height-for-age scores during childhood in Vietnam and during infancy in Africa. These findings add to the evidence on the enduring consequences of water pollution and identify a critical area for policy intervention

    Content: Salinity in surface waters is on the rise throughout much of the world. Many factors contribute to this change, including increased water extraction, poor irrigation management, and sea-level rise. To date no study has attempted to quantify the impacts on global food production. This paper develops a plausibly causal model to test the sensitivity of global and regional agricultural productivity to changes in water salinity. To do so, it utilizes several local and global data sets on water quality and agricultural productivity and a model that isolates the impact of exogenous changes in water salinity on yields. The analysis trains a machine-learning model to predict salinity globally, to simulate average global food losses over 2000-13. These losses are found to be high, in the range of the equivalent of 124 trillion kilocalories, or enough to feed more than 170 million people every day, each year. Global maps building on these results show that pockets of high losses occur on all continents, but the losses can be expected to be particularly problematic in regions already experiencing malnutrition challenges

    Content: The Middle East and North Africa Region encapsulates many of the issues surrounding water and human mobility. It is the most water-scarce region in the world and is experiencing unprecedented levels of forced displacement. Ebb and Flow: Volume 2. Water in the Shadow of Conflict in the Middle East and North Africa examines the links between water risks (harmful outcomes related to water, from droughts and floods to lack of sanitation), conflict, and forced displacement. It aims to better explain how to address the vulnerabilities of forcibly displaced persons and their host communities, and to identify water policy and investment responses. Contrary to common belief, the report finds that the evidence linking water risks with conflict and forced displacement in the region is not unequivocal. Water risks are more frequently related to cooperation than to conflict at both domestic and international levels. But while conflict is not necessarily a consequence of water risks, the reverse is a real and concerning phenomenon: conflict amplifies water risks. Since 2011, there have been at least 180 instances of intentional targeting of water infrastructure in conflicts in Gaza, Libya, the Syrian Arab Republic, and the Republic of Yemen. Forcibly displaced persons and their host communities face myriad water risks. Access to safe drinking water is a daily struggle for millions of forcibly displaced Iraqis, Libyans, Palestinians, Syrians, Yemenis, and international migrants in the region, heightening public health risks. Tanker trucks often help fill the gap; however, significant issues of water quality, reliability, and affordability remain. Host communities also face localized declines in water availability and quality as well as unplanned burdens on water services following the arrival of forcibly displaced persons. The reality of protracted forced displacement requires a shift from humanitarian support toward a development approach for water security, including structured yet flexible planning to deliver water services and sustain water resources for forcibly displaced persons and their host communities

    Series Statement: Ebb and flow / The World Bank Group Volume 1
    Content: Migration shapes the lives of those who move and transforms the geographies and economies of their points of departure and destinations alike. The water sector, and the availability of water itself, implicitly and explicitly shape migration flows. Ebb and Flow, Volume 1. Water, Migration, and Development presents new global evidence to advance our understanding of how fluctuations in water availability, as induced by rainfall shocks, influence internal migration, and hence regional development. It finds that cumulative water deficits result in five times as much migration as water excess does. But there are important nuances in why and when these events lead to migration. Where there is extreme poverty and migration is costly, water deficits are more likely to trap people than induce them to migrate. Water shocks can also influence who migrates. Workers leaving regions because of water deficits are often less advantaged than typical migrants and bring with them lower skills, raising important implications for the migrants themselves and receiving regions. Cities are the destination of most internal migrants, but even here, water scarcity can haunt them. Water shortages in urban areas, which lead to so-called day zero events, can significantly slow urban growth and compound the vulnerability of migrants. No single policy can be completely effective at protecting people and their assets from water shocks. Instead, the report puts forth a menu of overlapping and complementary policy options that target both people and places to improve livelihoods and turn water-induced crises into opportunities for growth. A key message is that policies that focus on reducing the impacts of water shocks must be complemented by strategies that broaden opportunities and build the long-term resilience of communities. Doing so will give individuals more agency to determine the best outcome for themselves and to thrive wherever they may choose to locate

    Content: Groundwater is our most important freshwater resource, but the lack of systematic analysis of its economic importance has evaded attention from policymakers and the general public-threatening the resource. "The Hidden Wealth of Nations: The Economics of Groundwater in Times of Climate Change" report offers new data and evidence that advances understanding of the value of groundwater, the costs of mismanagement, and the opportunities to leverage its potential
    Content: Its findings also reflect on the policy issues policymakers confront when attempting to align the private and social costs of groundwater use. A central message of this report is that groundwater needs to be politically prioritized and should be carefully managed through integrated cross-sectoral action to benefit society, the economy, and the environment
