The global population is growing at an accelerated rate, as is life expectancy. It is clear that the world’s population is heading toward urban areas, therefore, it is essential to implement specific measures that guarantee the survival and quality of life of its inhabitants.A more efficient and responsible use of energy resources, breathing new life into public spaces, using ICTs and introducing green areas into cities, are just some of the elements that are important to the younger population. It is therefore obvious that, in order to take advantage of all their ingenuity and creativity, a transformation in the education system is essential if we are to maximise these skills and adapt to the new era of knowledge.
Young initiatives for a technological and sustainable city

Organic power generation
Humans are a great source of energy and we move from here to there wasting that resource. One of the youngsters’ proposals is to install smart paving in major cities that absorb the impact of every step and transform it into energy. Each year four and a half million people visit the Sagrada Familia Basilica in Barcelona, 17 million tourists visit London each year and 65 million visit New York City.How much energy could those pedestrians generate? Perhaps not enough to light up an entire stadium, but enough to maintain passive and energy saving infrastructure systems. An interesting proposal that would contribute to energy efficiency and sustainability.Organic urban vegetable gardens
If the global trend is to abandon rural areas and move to the city, it is clear that the number of green areas needs to increase, not just for leisure and sports, but also for food production. In most countries, there are thousands of plots of land for sale, the majority of which are located in cities. The idea is that the owners of these plots assign this land until they decide, or manage, to sell them.Although the general idea of urban vegetable gardens is not new, the idea put forward by ShareUHort, which is the name given to this idea, includes a financial incentive, by paying for the use of these plots while they are unoccupied. The creation of organic vegetable gardens would also result in better use of rainwater and organic waste generated in households, thus tackling two problems experienced by all cities.Education systems under scrutiny
