Lessons from farmers' adaptive practices to climate change in China: a systematic literature review.

Due to the vulnerability and exposure of agriculture, farmers' adaptive strategies to climate change are important to food security and sustainable environment development. However, a systematic review is still absent, though there are many studies about farmers' adaptations to climate change, and few studies discuss their potential impacts on climate change. This article analyses farmers' adaptation strategies and their heterogeneities across regions in China via a systemic literature review.

Effects of WeChat use on the subjective health of older adults.

Objectives: In this study, the effect of WeChat use on the subjective health of older adults was examined.

Methods: Using 2018 China Health and Retirement Longitudinal Study (CHARLS) survey data, we attempted to rule out potential endogeneity bias by employing instrumental variable regression to estimate the effects of WeChat use on the health of older individuals. Mobile phone price was chosen as the instrumental variable, and the health of older adults was measured from two aspects: self-rated health and the Center for Epidemiological Studies of Depression Scale (CES-D10).

Development impacts of migration and remittances on migrant-sending communities: Evidence from Ethiopia.

This paper evaluates the development impacts of migration and remittances in migrant source communities by applying insights from the New Economics of Labor Migration (NELM) theory to Ethiopia's migration. Using household survey data, we empirically evaluate how household participation in migration arises and so that the subsequent labor losses and the influx of remittances affect income sources and asset accumulation of smallholder farm households. To account several econometric issues and consistently estimate the impacts of migration and remittances, we adopted three-stage least-squares method complemented with endogeneity and multicollinearity test.
