Urbanization proceeds globally and is often driven by migration. Simultaneously, cities face severe exposure to environmental hazards such as floods and heatwaves posing threats to millions of urban households. Consequently, fostering urban households’ resilience is imperative, yet often impeded by the lack of its accurate assessment. We developed a structural equation model to quantify households’ resilience, considering their assets, housing, and health properties. Based on a household survey (n = 1872), we calculate the resilience of households in Pune, India with and without migration biography and compare different sub-groups. We further analyze how households are exposed to and affected by floods and heatwaves. Our results show that not migration as such but the type of migration, particularly, the residence zone at the migration destination (formal urban or slum) and migration origin (urban or rural) provide insights into households’ resilience and affectedness by extreme weather events. While on average, migrants in our study have higher resilience than non-migrants, the sub-group of rural migrants living in slums score significantly lower than the respective non-migrant cohort. Further characteristics of the migration biography such as migration distance, time since arrival at the destination, and the reasons for migration contribute to households’ resilience. Consequently, the opposing generalized notions in literature of migrants either as the least resilient group or as high performers, need to be overcome as our study shows that within one city, migrants are found both at the top and the bottom of the resilience range. Thus, we recommend that policymakers include migrants’ biographies when assessing their resilience and when designing resilience improvement interventions to help the least resilient migrant groups more effectively.

Remittance from migrants reinforces forest recovery for China’s reforestation policy
Forests play a key role in the mitigation of global warming and provide many other vital ecosystem goods and services. However, as forest continues to vanish at an alarming rate from the surface of the planet, the world desperately needs knowledge on what contributes to forest preservation and restoration. Migration, a hallmark of globalization, is widely recognized as a main driver of forest recovery and poverty alleviation. Here, we show that remittance from migrants reinforces forest recovery that would otherwise be unlikely with mere migration, realizing the additionality of payments for ecosystem services for China’s largest reforestation policy, the Conversion of Cropland to Forest Program (CCFP). Guided by the framework that integrates telecoupling and coupled natural and human systems, we investigate forest-livelihood dynamics under the CCFP through the lens of rural out-migration and remittance using both satellite remote sensing imagery and household survey data in two representative sites of rural China. Results show that payments from the CCFP significantly increases the probability of sending remittance by out-migrants to their origin households. We observe substantial forest regeneration and greening surrounding households receiving remittance but forest decline and browning in proximity to households with migrants but not receiving remittance, as measured by forest coverage and the Enhanced Vegetation Index derived from space-borne remotely sensed data. The primary mechanism is that remittance reduces the reliance of households on natural capital from forests, particularly fuelwood, allowing forests near the households to recover. The shares of the estimated ecological and economic additionality induced by remittance are 2.0% (1.4%∼3.8%) and 9.7% (5.0%∼15.2%), respectively, to the baseline of the reforested areas enrolled in CCFP and the payments received by the participating households. Remittance-facilitated forest regeneration amounts to 12.7% (6.0%∼18.0%) of the total new forest gained during the 2003–2013 in China. Our results demonstrate that remittance constitutes a telecoupling mechanism between rural areas and cities over long distances, influencing the local social-ecological gains that the forest policy intended to stimulate. Thus, supporting remittance-sending migrants in cities can be an effective global warming mitigation strategy.

Understanding uneven patterns of forest use and tracking changes in the composition of forest residents are both important for sensitive forest policy and management. With increases in migration streams in several tropical forest regions, we need corresponding information about how new immigrants are influencing human-environment relations in sites of ecological significance. We use data from over 6500 household surveys collected by the Wildlife Conservation Society in three sites in Central Africa: the forests surrounding Nouabale-Ndoki National Park and Lac Tele Community Reserve in the Republic of Congo, and the Okapi Wildlife Reserve in the Democratic Republic of Congo. We compare household characteristics, livelihoods, and forest use among recent migrants (arriving within the past decade), longer-established households, and households belonging to an Indigenous group. We find that recent migrants are less likely to engage in forest-harvest-based livelihoods and harvest several types of forest foods and fibers less frequently than other households. Recent migrants also tend to be wealthier, younger, and over-represented in salaried jobs. Meanwhile, Indigenous households are 3 to 16 times more likely to participate in a forest-based livelihood, depending on the site. Other consistent predictors of forest harvest include village, age of the household head, household size, whether a household is female-headed (−), and wealth (−). Many trends hold broadly across all three sites, but there are also site-specific patterns related to differences in remoteness and economic opportunities. We conclude with reflections about what the changing make-up of forest-proximate communities might mean for forest management and governance.more » « less

Rural out-migration was a rare socio-economic phenomenon when community forestry began in the 1980s in Nepal. Now, out-migration significantly influences nearly every aspect of rural livelihoods in the country. However, it is unclear how out-migration affects community forestry governance, which is essential for sustainable rural development. Therefore, this paper addresses the following research question: Does rural out-migration affect forest users’ participation in community forestry decision-making and management practices? This paper draws on data collected from an extensive survey of 415 households from 15 community forest user groups in 2 Mid-Hill districts of Nepal. The research used ordered-logit regression to model the impacts of out-migration on participation in forest management and decision-making, while controlling for a number of other socio-economic factors. The model results show that total household size and number of internal migrants, together with multiple resource characteristics and institutional attributes, were major factors affecting participation in decision-making and forest management. However, the number of international migrants did not have a significant role in determining the levels of the participation. This study provides valuable insights for future community forestry policymaking that aims to address the effects of out-migration on community forest management in Nepal.more » « less

Nepal’s forest cover nearly doubled over the last three decades. While Community Forest (CF) management and agricultural abandonment are primary drivers of forest cover expansion, the contribution of afforestation on privately managed land is not well documented. We mapped forest cover change from 1988 through 2016 in 40 privately managed sites that transitioned from agriculture to forest and assessed how agricultural abandonment influenced private land management and afforestation. We used a mixed method analysis to integrate our 29- year Landsat satellite image-based record of annual forest cover with interview data on historical land cover and land use dynamics from 65 land managers in Bagmati Province. We find that privately managed land accounted for 37% of local forest cover gain, with mean forest area within private forests growing from 9% to 59%. Land managers identified two factors driving these gains on private land: implementation of CF man- agement in adjacent government forests and out-migration. These previously undocumented linkages between forest cover gain on private land and CF management merits further research in community forests and calls for greater policy and technical support for small-scale timber growers and rural households who rely on private forests for income generation.more » « less

This study investigates the effect of international migration experience on entrepreneurship in sending areas. To identify prosperous businesses that create jobs and encourage economic development, this study isolates businesses other than street-vending enterprises with non-family employees. Retrospective life history data from the Mexican Migration Project (N = 11,789 persons & 146,372 person-years) was used to estimate the annual probability of becoming an entrepreneur across 170 Mexican communities between 1975-2017. This study found that (1) any prior migration experience increases the probability of entrepreneurial entry relative to non-migrants; (2) accumulated months of migration experience are positively associated with the probability of entrepreneurial entry; (3) undocumented status is associated with a lower probability of entrepreneurial entry. The positive effect of accumulated migration experience on entrepreneurship suggests that international migrants can accumulate human and financial resources that are essential to early stage entrepreneurship. Thus, entrepreneurship represents an important pathway through which international migration can encourage economic development in less developed regions. At the same time, the results suggest that that immigration policies in receiving countries can undercut migrants’ capacities to mobilize resources and contribute to economic development upon return. These findings suggest that target migration creates a win-win by addressing labor shortages in receiving countries, while transferring resources to sending areas that enable economic mobility and development.more » « less
