Climate change threatens smallholder agriculture and food security in the Global South. While cropland expansion is often used to counter adverse climate effects despite ecological trade-offs, benefits for diets nutrition remain unclear. This study quantitatively examines relationships between anomalies, forest loss from expansion, dietary outcomes Nigeria, Africa’s most populous country. Combining high-resolution data on cover variables within random panel regression models, we find that 25 31% of annual linked variability. Using georeferenced household survey data, then changes have a significant positive association with child diet diversity—a key proxy nutritional adequacy—while does not, suggesting such conversions may be an ineffective adaptation strategy improving nutrition. Our findings highlight potential nutrition-sensitive enhance yields, promote nutritious cropping choices, protect remaining forests.

Climate anomalies, such as floods and droughts, well gradual temperature changes have been shown to adversely affect economies societies. Although studies find that climate change might increase global inequality by widening disparities across countries, its effects on within-country income distribution little investigated, has the role of rainfall anomalies. Here, we show extreme levels precipitation exacerbate inequality. The strength direction effect depends agricultural intensity an economy. In high-agricultural-intensity anomalies negatively impact sector lower incomes at bottom end generate greater Our results indicate a 1.5-SD in from average values 35-times-stronger shares for countries with high employment agriculture compared low sector. Projections modeled future reveal highly heterogeneous patterns scale, worsening economies, particularly Africa. findings suggest degree dependence are crucial factors assessing negative impacts distribution.

Climate-driven changes in precipitation amounts and their seasonal variability are expected many continental-scale regions during the remainder of 21st century. However, much less is known about future predictability precipitation, an important earth system property relevant for climate adaptation. Here, on basis CMIP6 models that capture present-day teleconnections between previous-season sea surface temperature (SST), we show change to alter SST-precipitation relationships thus our ability predict by 2100. Specifically, tropics, from SSTs projected increase throughout year, except northern Amazonia boreal winter. Concurrently, extra-tropics likely central Asia spring The altered predictability, together with enhanced interannual poses new opportunities challenges regional water management.

Instrumental variable (IV) analysis assumes the instrument only affects dependent via its relationship with independent variable. Other possible causal routes from IV to are exclusion-restriction violations and invalidate instrument. Weather has been widely used as an instrumental in social science predict many different variables. The use of weather variables represents strong prima facie evidence exclusion for all studies using IVs. A review 288 reveals 192 previously linked weather: representing potential violations. Using sensitivity analysis, I show that magnitude these is sufficient overturn numerous existing results. conclude practical steps systematically literature identify when designs.
