Around 250 million migrants currently live outside their countries of birth, making up approximately 3.5 percent of the world population. Despite the widespread perception of a global migration crisis, this ratio has stayed remarkably stable since the end of the Second World War and lags well behind other major metrics of globalization – international trade, capital flows, tourism etc. A more remarkable statistic is that refugees, at around 15 million, account for 6 percent of the migrant population and only 0.2 percent of world population. In other words, we can fit all refugees in the world in a city with an area of 5000 square kilometers – roughly the size of metropolitan Istanbul or London or Paris – and still have some space left over.
Inorganic fertilizer use by smallholder farmers is one way to boost soil fertility and associated crop-yields and farm incomes. Yet fertilizer use remains the lowest where yield increase is needed the most. Per the World Development Indicator database , inorganic fertilizer use averages 154 kgs/hectare in middle-income countries, while in low-income countries it is less than one-tenth this level at 13 kgs/hectare. What is driving this situation? And are at times fiscally expensive programs, such as government subsidies, commonly used in low income countries, the right solution?
