A Estaca Zero da Mudança Climática

OUAGADOUGOU – O Burkina Faso localiza-se no coração do Sahel, e isso significa que é um dos países mais vulneráveis do mundo no que respeita à mudança climática. Os seus agricultores poderão saber pouco sobre as causas físicas do aquecimento global, mas conhecem os seus efeitos – com especial atenção à grande variabilidade dos regimes de pluviosidade, desde secas a cheias, que levam a colheitas perdidas, à erosão das pastagens, e a crises alimentares.

Em consequência, o conceito de agricultura sustentável tem ganho terreno nos últimos anos, tanto internacionalmente como no Burkina Faso. O termo faz parte do discurso político e tornou-se numa abordagem fundamental para o desenvolvimento agrícola global. Na verdade, a sustentabilidade é hoje uma força motriz na agricultura – e tão importante como foi a produtividade em décadas passadas.

O conceito de agricultura sustentável está inextricavelmente ligado ao de desenvolvimento sustentável, definido pela primeira vez em 1987 como um modelo de crescimento económico “que satisfaz as necessidades do presente, sem comprometer a capacidade das gerações futuras satisfazerem as suas”.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    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.
