E-book Designing Urban Food Policies : Concepts and Approaches
ollowing the reign of nation states, there is every reason to believe that the twenty-first century will be a new era for cities.First because, from a structural standpoint, currently over half of the world popu-lation is urban (compared to 30% in 1950), and it will increase to two-thirds by 2050 according to the United Nations (2014). Medium-sized cities have consider-able weight in this process since half of the urban population presently lives in cities of fewer than 500,000 inhabitants, while 1 urban dweller in 8 lives in a megacity of more than 10 million inhabitants. Africa and Asia—two continents that are still mainly rural—will be the locus of most of this urban population growth (2.5 billion more people in the next 35 years). Together, China, India and Nigeria will account for nearly 40% of the world’s population growth by 2050. This raises major chal-lenges in meeting housing, infrastructure, transportation, energy, employment, edu-cation, health and, of course, food needs.Second because cities are gaining tremendous social, political and economic power. This power rises which—in addition to the demographic weight that cities represent—may be partly explained by production system changes taking place worldwide in a globalization setting and by the financial disengagement of States in land-use planning. Cities represent powerful local hubs that States can rely on to manage transitions to new development models. Cities have thus extended and asserted their power in many areas of social life to transform an ambient ‘ecodesire’ into tangible local reality (Haëntjens 2009) while developing their scope of opera-tions to ensure their sustainability (Emelianoff 2007). This trend is reflected by the growing number of territorial sustainable development policies and the development of global networks of local urban governments. At the 1992 United Nations Conference on Environment and Development (Rio Earth Summit), local authorities in each country were called upon to set up local Agenda 21 programmes tailored to their local setting, considering that: ‘[...] As the level of governance closest to the people, they play a vital role in educating, mobilizing and responding to the public to promote sustainable development’ (Chapter 28 on local authorities’ initiatives in support of Agenda 21).
