Population growth, rapid urbanization, and dietary changes are placing tremendous pressure on food systems, particularly in developing countries. Based on current income, population and consumption trends, the Food and Agriculture Organization of the United Nations (FAO) estimates that, by 2050, some 50 percent more food will be needed to satisfy the extra demand compared to 2013 (Alexandratos and Bruinsma, 2012). The challenges posed by rapid growth in food demand are intensified by the effects of climate change on agricultural systems, including crops, livestock, forestry and fisheries.

Vegetable cultivation is a survival strategy for the urban population, especially with the increasing population, urbanization, and high unemployment rate. For decades, men have practiced vegetable cultivation in Tamale's metropolitan city, with women being involved at the last node of the value chain – marketing. Women are known as market queens, and culturally, sell foodstuff in the market, unlike men who can’t do the same. These market queens buy vegetables from farm gates and sell them at wholesale prices to other market women who retail them in the market.

This course includes self-paced e-learning training modules which present descriptive and practical step-by-step guidance on how to compute SDG 11+ indicators. It is aimed at strengthening national and city capacities in collecting, analyzing, and monitoring the urban SDG indicators.

This training course is intended for all the professionals involved in monitoring and reporting on SDG 11 indicators and anyone who wishes to get guidance in the monitoring process.

Diamonds in the Delta (DiD) is an international research-action network of scholars, water professionals and civil society advocates who are concerned about how climate change compounds problems of flooding and subsidence in delta cities. We – the people in the network – are united in our conviction that the needs, experiences and aspirations of communities that are actually or potentially most affected by these problems should be the focus when designing and implementing solutions.

Over the past half-century, the risk of urban flooding in Dar es Salaam has increased due to changes in land cover coupled with climatic changes. This paper aimed to quantify the impacts of climate and land-cover changes on the magnitudes and frequencies of flood runoffs in urban Dar es Salaam, Tanzania. A calibrated and validated SWAT rainfall-runoff model was used to generate flood hydrographs for the period 1969–2050 using historical rainfall data and projected rainfall based on the CORDEX-Africa regional climate model.

The preservation of suburban agricultural land in the face of rapid urbanization in the West African region has been a major problem in recent decades. This paper examines the land tenure strategies used by farmers in relation to their assessments of the impact of urban growth. It is based on individual surveys conducted among farmers and landowners on the outskirts of the city of Lomé in Togo. This study reveals that perceptions differ according to gender and that women—although marginalized by customary land tenure—play an important role in maintaining suburban agricultural land.

This paper considers the foundations of contemporary African urban economies and how these intersect with the evolution of urban politics, carving a route through a wide range of existing literatures relevant to the politics and political economy of African urban development. It considers the economic and demographic drivers of urbanisation in Africa and their consequences for urban restructuring and uneven development, before turning to the forms of urban politics that have emerged alongside, responded to and also helped shape these urban economic developments.

México ha transitado por un proceso de cambios territoriales importantes en las últimas décadas; sin embargo, las políticas de vivienda de los últimos años, las modificaciones constitucionales sobre la propiedad agraria y la falta de una aplicación rigurosa de los instrumentos de planeación y de Ordenamiento Territorial (OT), entre otros factores, aceleraron la expansión urbana sobre áreas agrícolas y naturales. Si bien los procesos de urbanización y metropolización han favorecido el desarrollo económico del país, también han tenido efectos negativos, tales como un aumento de la desigualdad

Countries in Southeast Asia have been developing quickly from a predominantly rural to predominantly urban society, leading to a rapid increase in urban land. This increase in urban land has mainly occurred in river deltas and floodplains, exposing humans and human assets to flood hazard. Here we present an assessment of current and future flood risk in five countries of mainland Southeast Asia, using a new modeling approach that accounts for differences in urban land systems.

Today, the Coalition for Urban Transitions releases a new report ‘Seizing the Urban Opportunity’, which provides insights from six emerging economies on how national governments can recover from COVID-19, tackle the climate crisis and secure shared prosperity through cities. Launching as a call to action for national governments ahead of COP26 in Glasgow, it builds on the Coalition’s flagship 2019 report: Climate Emergency, Urban Opportunity.

This study assesses the global mountain population, population change over the 1975–2015 time-range, and urbanisation for 2015. The work uses the World Conservation Monitoring Centre (WCMC) definition of mountain areas combined with that of mountain range outlines generated by the Global Mountain Biodiversity Assessment (GMBA). We estimated population change from the Global Human Settlement Layer Population spatial grids, a set of population density layers used to measure human presence and urbanisation on planet Earth.
