The mosquito Aedes (Ae). aegypti transmits the viruses that cause dengue, chikungunya, Zika and yellow fever. We investigate how choosing alternate emissions and/or socioeconomic pathways may modulate future human exposure to Ae. aegypti. Occurrence patterns for Ae. aegypti for 2061–2080 are mapped globally using empirically downscaled air temperature and precipitation projections from the Community Earth System Model, for the Representative Concentration Pathway (RCP) 4.5 and 8.5 scenarios.

The global human population now exceeds 7 billion and is projected to reach 10 billion around 2060. While population growth has been associated with certain benefits (e.g., economies of scale, technological advancements), theoretical models, probabilistic projections, and empirical evidence also indicate that this growth could increase the likelihood of many adverse events (e.g., climate change, resource shortages) and the impact of these events, as more people are exposed to the outcomes.

The continent’s population will continue to soar with the birth of almost two billion babies in the next 35 years and eventually reach 4.2 billion by 2100. An increasingly crowded Africa will have to invest in reproductive health and education to avert a disaster.

East Asia and Pacific is aging faster – and on a larger scale – than any other region in history, which could lead to a steep drop in the size of its workforce and sharp increases in public spending on pensions, health care and long-term care in the coming decades, according to a new World Bank report.

Global dimming refers to the decrease in surface solar radiation (SSR) observed from the 1960s to the 1980s at different measurement sites all around the world. It is under debate whether anthropogenic aerosols emitted from urban areas close to the measurement sites are mainly responsible for the dimming. In order to assess this urbanization impact on SSR, we use spatially explicit population density data of 0.08° resolution to construct population indices (PI) at 157 high data quality sites.

This book lays out a range of policy actions that are needed at the various phases of the demographic transition and uses global and regional experiences to provide evidence on what has worked and what has not.

This year’s Global Monitoring Report, produced jointly by the World Bank and International Monetary Fund, details the progress the world has made towards global development goals and examines the impact of demographic change on achieving these goals.

Australia's population growth has slumped to its lowest level in a decade, figures released by the Australian Bureau of Statistics (ABS) have revealed on Thursday.

Managing freshwater resources sustainably under future climatic and hydrological uncertainty poses novel challenges. Rehabilitation of ageing infrastructure and construction of new dams are widely viewed as solutions to diminish climate risk, but attaining the broad goal of freshwater sustainability will require expansion of the prevailing water resources management paradigm beyond narrow economic criteria to include socially valued ecosystem functions and services.

Cryptosporidium is a protozoan parasite that can cause diarrhoea. Human faeces are an important source of Cryptosporidium in surface waters. We present a model to study the impact of sanitation, urbanization and population growth on human emissions of Cryptosporidium to surface waters. We build on a global model by Hofstra et al and zoom into Bangladesh and India as illustrative case studies.
