Without healthy soils, it is not possible to produce healthy food. But soils do not just produce food: they
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.
Understanding the combined and separate effects of climate and land use change on the water cycle is necessary to mitigate negative impacts. However, existing methodologies typically divide data into discrete (before and after) periods, implicitly representing climate and land use as step changes when in reality these changes are often gradual. Here, we introduce a new regression-based methodological framework designed to separate climate and land use effects on any hydrological flux of interest continuously through time, and estimate uncertainty in the contribution of these two drivers.
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.
Suzhou city was the cultural centre of ancient south China. It continues the urban pattern of more than 800 years ago. Suzhou gardens are the essence of Chinese gardening art, as well as the valuable world cultural heritage site. This paper compared the evolution in the distribution and scale of Suzhou gardens among five historical periods, and discussed the influence of urbanization on gardening.
Senegal currently has a complex and poorly regulated system of land governance, which — combined with an urbanisation trend and increasing outsider interest — is leading to land privatisation and a consequent reduction in the availability of cultivable land for small producers. Young farmers in particular are struggling to gain sufficient access to land to maintain viable enterprises.
The National Urban Assessment for Armenia provides a snapshot of the country’s urban sector and offers insights to achieving prosperous and sustainable cities. Armenia is highly urbanized, with the population concentrated in Yerevan and its surrounding areas given the capital’s geopolitical, economic, and cultural legacy. Opportunities exist to develop well-planned infrastructure along with balanced resource distribution among Yerevan and other cities, while leveraging Armenia’s cultural and environmental assets.
This Country Profile (CP) of the Republic of Armenia is the nineteenth in the series and the second review done for the country. The first was prepared in 2004 and the analyses covered only the housing sector. This CP is an in-depth analyses of the housing, urban development and land management sectors of the Republic of Armenia. It provides policy recommendations on these sectors, while focusing on specific challenges and achievements.
La ville de N’Djamena, capitale de la République du Tchad connaît sans cesse, depuis sa création en 1900, une extension urbaine qui se traduit par une consommation démesurée de l’espace. Un état de fait rendu possible durant des décennies par différents facteurs antagonistes issus de l’absence et/ou de l’insuffisance de l’autorité de l’Etat. Par ailleurs,d’autres facteurs contextuels s’invitent pour donner lieu à des effets irréversibles tels que: la prolifération de quartiers sousintégrés.
This report uses unique household survey data from 24,870 respondents in 33 countries in Latin America, Europe, Africa and Asia to investigate correlations between demographic, economic and spatial characteristics and perceived tenure insecurity.
ncreasing flood risks in Thailand are leading to new challenges for flood management and subsequently for livelihoods, which are still significantly agricultural. Policy makers prefer building flood protection infrastructure over utilizing non-structural measures like urban planning regulations to mitigate risks. We argue that unplanned urbanization intensifies flood risks and livelihood vulnerability and may even create new poverty patterns in peri-urban areas.
Urban planners are entrusted with the power to make critically important, long-term decisions that determine the future development of cities and towns around the world. The decisions they take shape the urban environment and directly affect the lives and livelihoods of entire communities.
