Rethinking the urban role of nature in climate change. The project for an urban green wall. – The paper discusses the Green Urban Oases project that aims to reconverse more than 500,000ha of land into new urban forests and restor about 300,000ha of forests in the Sahel and Central Asia. The project is part of a broader reflection that sees cities at the centre of the debate on climate change and aims to rethink the relationship between society and nature. Since, on the one hand, nature is increasingly becoming a protagonist in the process of urban adaptation, on the other hand it seems continuing to be conceptualised only in terms of human needs.
The aim of this contribution, part of a broader work, is to reflect on the role that nature-based solutions, implemented in particular through the above-mentioned project, have in cities and if they represent ways for the ‘nature’ to go beyond the marginal, passive and anthropocentric interpre-tation it has had until now in climate change depate.

Covid-19 and the spread in African spaces. A geo-anthropological overview. – It is not yet known how Covid-19 will spread in the African continent; many genetic, climatic, sociological, demographic factors can influence its evo-lution. There is no doubt that less developed countries such as the African ones have a weak capacity to respond. According to data provided by the WHO, UN-OCHA and other accredited sources, the spread of the Virus in the Continent appears limited compared to other areas of the Planet; the most affected country is South Africa. The governments of some countries have reacted by implementing, on the European mod-el, procedures such as curfew (Egypt) or lockdown (South Africa and Nigeria). The research aims to develop a framework on the spread of Covid-19 in Africa and the socio-economic impact of the measures im-plemented in the emergency. Another aim is to highlight the changes in the socio-anthropological aspects, considering that many African socie-ties define themselves on the basis of ethnicity, interaction with other communities and therefore social distancing measures will not be as ef-fective as elsewhere.
