A Synthesis of Global Urbanization Projections

Global nitrogen and phosphate in urban wastewater for the period 1970 to 2050

[1] This paper presents estimates for global N and P emissions from sewage for the period 1970–2050 for the four Millennium Ecosystem Assessment scenarios. Using country-specific projections for population and economic growth, urbanization, development of sewage systems, and wastewater treatment installations, a rapid increase in global sewage emissions is predicted, from 6.4 Tg of N and 1.3 Tg...

Livestock and global change: emerging issues for sustainable food systems.

The global food system is experiencing profound changes as a result of anthropogenic pressures. The ever-increasing human population (more than 9 billion by 2050), together with changes in consumption patterns (i.e., increasing demand for livestock products) caused by urbanization, increasing incomes, and nutritional and environmental concerns, is shaping what we eat, who eats, and how much, mo...

People Perception Regarding Possible Impact of Urbanization on Environmental Degradation in Islamabad

Urbanization is the process in which green space (fields, trees, wetlands, etc.) is converted into black space (concrete and asphalt). Urbanization occurs because people move from rural areas to urban areas. This usually occurs when a country is still developing. Slums and its consequences of overcrowding lack of sanitation, global warming, air pollution, water pollution and loss of forest cove...

Interpreting UN Urbanization Projections Using a Multi-state Model

Food for an Urban Planet: Challenges and Research Opportunities

In 2014, Khoo and Knorr (1) identified the global shift in population demographics as one of the twenty-first century grand challenges, which warrants research prioritization by the food and nutrition communities. A persistent global growth trend toward urbanization can be attributed to this demographic shift. Satterthwaite et al. (2) characterized urbanization as “the increasing share of a nat...
