Producing adequate food to meet global demand by 2050 is widely recognized as a major challenge, particularly for Africa south of the Sahara, including Tanzania (Godfray et al. 2010; Alexandratos and Bruinsma 2012; van Ittersum et al. 2016). Increased price volatility of major food crops (Koning et al. 2008; Lagi et al. 2011) and an abrupt surge in land area devoted to crop production in recent years (Grassini et al. 2013) reflect the powerful forces underpinning this challenge.
Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably.
A manhã de hoje foi de desolação nas aldeias afetadas pelo fogo que lavra desde domingo, em Alijó, no distrito de Vila Real, com a constatação comum a várias pessoas que vivem da agricultura: perderam tudo.
“Fiquei sem anda, perdi tudo: pinheiro, castanheiros”, desabafava Sónia Cardoso, junto à outros populares no cruzamento de Chã, que dá acesso a várias aldeias.
Sónia tem propriedades nas quatro frentes do fogo e nos quatro sítios, diz, ficou sem nada.

In conflict situations, peace settlements and cease-fire agreements may often, end violent conflicts, but do not prevent renewed violence or guarantee a permanent end to conflicts.5 According to the World Bank, chances that renewed conflicts will erupt are high and even higher when control over natural resources is at stake.6 In the past two decades alone, Africa has experienced violent conflicts with successive cease-fire agreements and peaceful settlements, which have often been followed by outbreaks of new conflicts.
Almost one in seven people around the world are chronically hungry, lacking enough food to be healthy and lead active lives. This is despite the fact that enough food exists for all of the world’s people.1 Agricultural policies, the prices of certain food commodities such as meat and grain and economic development hugely impact food security, but demographic trends also play a role.
The story of urbanization in Kenya should be one of cautious optimism. As an emerging middle-income country with a growing share of its population living in urban areas and a governance shift toward devolution, the country could be on the verge of a major social and economic transformation. How it manages its urbanization and devolution processes will determine whether it can maximize the benefits of its transition to a middle-income country.
"We think it's a crisis when one-in-three households - one-in-three citizens that live in cities - don't have adequate, secure or affordable housing"
TEPIC, Mexico, July 12 (Thomson Reuters Foundation) - Booming cities in developing nations should upgrade slums, build on underused land and promote rental choice to tackle a fast-growing crisis caused by a shortage of affordable housing, researchers said on Wednesday.
