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?
The potential for expanding the industrial sectors of African countries is substantial – this was a message I delivered on a recent trip to Italy, Tanzania, Mozambique and Malawi. This can happen through an improved understanding of the mechanics of economic transformation as well as by focusing on how such countries can follow their comparative advantage in natural resources and labor supply.
During my site visits and meetings with the private sector for the African segments of my trip, I became more convinced than ever of the strong untapped potential for private sector-led industrialization. Yet that can only happen when the government plays a facilitating role, such as by overcoming information asymmetries, coordination failures and externalities associated with first-mover actions. In Tanzania, initial experiments with industrial parks look promising, as do agricultural development projects and rural transport initiatives currently under way. In the case of industrial parks, it’s important to have a one-stop shop for registration and other administrative obligations, adequate electricity and water supply, and good transport/logistics links.
By the end of 2009, an estimated 5.2 million people in low- and middle-income countries received antiretroviral therapy (ART). In sub-Saharan Africa, nearly 37% [34%–40%] of people eligible for treatment had access to those life-saving medicines (UNAIDS 2010). This is an extraordinary achievement, considering that as recently as 2003, relatively few people living with HIV/AIDS had access to ART in Africa. The scaling-up of ART in Africa and other regions has saved the lives of countless people and we hope will continue to do so.
At the same time, access to HIV/AIDS treatment might have transformed the perception of AIDS from a death sentence to a manageable, chronic condition, not necessarily different from any other chronic disease. Such a change in perception could lead to change in sexual behaviors. If AIDS is not perceived as a killer disease anymore, it might induce complacency and increase risky behaviors and the mixing between higher- and lower-risk groups in the population. That’s what has been described as the “disinhibition” hypothesis.
