Article Synopsis
- Climate change is heightening the risk of drought in sub-Saharan Africa, where high HIV prevalence exists, potentially increasing HIV transmission through various social and economic mechanisms.
- Data from HIV surveys in 2016 across five countries were analyzed, linking survey data with local drought conditions to explore how drought affects poverty, sexual behaviors, and HIV acquisition.
- Findings indicate that drought increased poverty levels in rural areas and was associated with higher rates of risky sexual behaviors, especially among women, leading to a significantly greater likelihood of recent HIV infection in drought-affected rural women.
Background: Periods of droughts can lead to decreased food security, and altered behaviours, potentially affecting outcomes on antiretroviral therapy (ART) among persons with HIV (PWH). We investigated whether decreased rainfall is associated with adverse outcomes among PWH on ART in Southern Africa.
Methods: Data were combined from 11 clinical cohorts of PWH in Lesotho, Malawi, Mozambique, South Africa, Zambia, and Zimbabwe, participating in the International epidemiology Databases to Evaluate AIDS Southern Africa (IeDEA-SA) collaboration.
Objective: To assess the potential bidirectional relationship between food insecurity and HIV infection in sub-Saharan Africa.
Design: Nationally representative HIV impact assessment household-based surveys.
Setting: Zambia, Eswatini, Lesotho, Uganda and Tanzania and Namibia.
Article Synopsis
- Armed conflicts lead to food insecurity by causing cropland abandonment and making it hard to collect relief information.
- Satellite remote sensing can effectively gather data during these conflicts and assess food security conditions.
- Analysis of satellite images in South Sudan revealed a 16% decrease in cultivated land from 2016 to 2018, underlining the impact of war on food supply and highlighting remote sensing's importance in improving aid distribution.
