L’alimentazione nell’era dei biocarburanti

ROMA – Negli ultimi anni, i biocarburanti sono diventati il pomo della discordia. Per qualche motivo, una fonte di energia rinnovabile prodotta da materiale organico equivale a una bacchetta magica nella lotta contro il cambiamento climatico. Ma altri vedono i biocarburanti come una minaccia esistenziale, dal momento che le piante usate per crearle si contendono il terreno agricolo e l’acqua che in caso contrario sarebbero utilizzati per far crescere gli alimenti. 

Tuttavia si tratta di una falsa dicotomia. La scelta non può essere tra il cibo e il carburante. Possiamo fare buon uso di entrambi. Se sussistono le condizioni giuste, i biocarburanti possono diventare dei mezzi efficienti per aumentare la sicurezza sul cibo fornendo agli agricoltori poveri una fonte di energia sostenibile e conveniente.

In alcuni Paesi dell’Africa senza sbocchi sul mare, la benzina costa tre volte la media globale, rendendo i prezzi del carburante una delle principali barriere alla crescita agricola. Estendere l’uso di biocarburanti in queste regioni potrebbe dare impulso alla produttività e creare nuovi posti di lavoro, specialmente nelle zone rurali. L’effetto può essere anche maggiore se la domanda aggiuntiva di materie prime create da biocarburanti è stata soddisfatta da imprese agricole a conduzione familiare e da produttori su piccola scala.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
