Currently, climate changes or alterations are known to be reflected on the stable isotope ratios of Hydrogen, Nitrogen, Carbon, Oxygen and Sulphur present in atmospheric gas forms, fresh or ocean water, as well as in plants and animals and organic matter in the soil. Samples from those matrices can provide a record for such changes across a given length of time and / or space. Also, ecological and physiological processes often reflect on stable isotope ratios, again setting a record in plant, animal or other living tissues.

The continuous urban development associated with the growth of the world population has become one of the most important challenges of the present time. Today, cities accommodate more than 54% of the world's population, a proportion that is expected to increase to 70% by 2050. Trends in urbanization show that cities are becoming more complex and heterogeneous social-ecological systems with growing demand for natural resources mainly for infrastructure, housing, food, water, and energy.

A sessão irá refletir sobre as cidades do futuro, um tema recorrente nos media pela incerteza da sua evolução.

There is increasing evidence of the effects that excess nitrogen has on semi-natural ecosystems globally, affecting vegetation, soils and ecosystem processes. Although coastal systems can be highly dynamic and in some cases receive inputs of nitrogen from marine sources, sand dune ecosystems have also been shown to be sensitive to nitrogen.

Addressing the key challenges that the energy sector faces to ensure a sustainable future requires technology progress and innovation. Energy consumption is expected to grow 40% in the next two decades, putting increased pressure on resources and the environment. Meeting these challenges will require innovation to provide the abundant, clean and affordable energy the world needs. 

Este evento com duração de dois dias, terá conferências, debates, workshops e espaços de conversa com alunos recém-graduados e empresas.

Os painéis das II Jornadas da Energia terão os seguintes temas principais:

A two-week international training school on the multiple effects of atmospheric nitrogen in ecosystems. The school will provide training in a holistic approach of key aspects related to N issues under the WAGES concept (nitrogen threats to Water, Air, Greenhouse gases balance, Ecosystems and Soils), with a long-term perspective. This edition will focus on Air quality, Ecosystems and Biodiversity.
