Food security challenges are "complex, immense, frightening and urgent"

In an opinion piece in the Financial Times Paul Polman of Unilever reminds us that, due to a rising population and changing consumption habits, we will need to produce the same amount of food in the next 40 years as we did in the past 8,000.

He calls for increased investment in African agriculture; and for developing country governments need to create long-term partnerships with the private sector, donors and civil society, to stimulate investment in commercial agriculture.

He references the Copenhagen Consensus, which concluded that an investment in fighting malnutrition would benefit people more than any other type of investment – with a return of $30 for every $1 invested.
