Gairebé el 40% dels joves espanyols entre 18 i 24 anys utilitzen telèfons 'intel·ligents’, els anomenats smartphones. Més enllà de les trucades i els wassups, els smartphones o mòbils intel·ligents són dispositius tecnològicament punters, amb prestacions que els converteixen en autèntics ordinadors en miniatura.

Precisament amb la idea d’aprofitar la tecnologia dels smartphones i les tablets, un equip d’investigadors del Barcelona Supercomputing Center – Centro Nacional de Supercomputación (BSC-CNS) està dissenyant un prototip del que serà el primer superordinador del món basat en tecnologia de telèfon mòbil.

Amb la idea d’aprofitar l’eficiència que aporta el consum energètic dels smartphones i les tablets – la major part del temps no estan endollats a la xarxa elèctrica i funcionen sense sobre escalfar-se –, un equip de recerca està dissenyant el prototip d’un nou supercomputador amb major capacitat de càlcul i que no augmenti la despesa energètica. És l’objectiu de Mont-Blanc, projecte coordinat per Àlex Ramírez, investigador del Barcelona Supercomputing Center – Centro Nacional de Supercomputación (BSC-CNS) i professor del Departament d'Arquitectura de Computadors.

Participatory Systems of Guarantee (PSGs) arise when proposed by civil society, revolving around the production and commercialization of ecological foods. They are constructed as an alternative to the model of certification by a third party, in order to guarantee that productive initiatives which are not covered by the official system are still able to access the certified product sector / market.



Their dynamism is that they are constantly evaluating and reviewing their structures and procedures, as a result of their constant interaction with their environment. Given this characteristic, in reality PSGs are reaching great levels of complexity, not only internally – as part of the same system – but in a global sense, where organizations are using a number of them in line with diverse criteria.



Their social design and focus on the system, as well as the sensitivity that they show for processes of co-evolution, allow us to visualize them as one of the possible tools that will permit the transition from one system to another.



The systems themselves (integrated in political agroecology), and the activities that they encourage, widen the options for agroecological approaches. These can then be applied in territories that are working towards greater sustainability.

Diàleg. Due to global food shortages, some stakeholders defend industrial agriculture versus agroecology
Can agroecology organic production sustain the global population without increasing the land currently under cultivation?

Agriculture can be described in terms of two competing models: On the one hand, the industrial model operates within a productivist industrial discourse. Input intensive monocultural methods have resulted in ecological and socioeconomic negative externalities. These affect not only ecosystem services and rural populations but also reverberate throughout the agrifood system.
On the other hand, agroecology can be placed within a holistic paradigm that promotes interdisciplinary collaboration between researchers, growers, consumers and other stakeholders to work towards an agrarian sector that operates under ecological and socioeconomic principles.
An important argument made by proponents of the industrial model is that ecological models of agriculture do not produce as much food as the conventional model and therefore would cause global food shortages if implemented on a large scale.Questions to speakers
1- Who should benefit from the use of agricultural land? For what uses and needs? Who should decide?
2- What is the role of biotechnology in agriculture? And what is the role in agroecology? Angel and/or devil?

This presentation will be split in two parts. At first, a general overview will be made about the present situation and main roles of small-scale livestock farming in the world. Secondly, the specific case of organic livestock farming in Catalonia will be more in-depth examined.

Backcasting is an instrument to develop a path towards a realistic desirable future for a given theme (e.g. sustainable agriculture, sustainable food etc). It involves the following steps: problem definition, establishment of terms of reference for solutions (here, in relation to sustainability and to functionality), brief description of some future views, selection/construction of a final future view, establishment of backcasting steps (working backwards from the future view).

As part of the talk, the "selection of relevant future trends" will be discussed. This involves making an inventory of trends relevant to the theme and categorising them graphically with respect to probability and impact. Taking such steps allows the most probable scenarios to be taken into account when establishing future views.
