Scaling up innovations in agriculture: Lessons from Africa

For too long the narrative surrounding Africa’s agri-food sector has been one of limited opportunity, flat yields and small farms. It’s true that Africa is still producing too little food and value-added products despite recent efforts to increase investment, and that agricultural productivity has been broadly stagnant since the 1980s as shown in the 2018 African Agriculture Status Report.

Confronting tobacco illicit trade: a global review of country experiences

Sheila Dutta's picture



Illicit trade in tobacco products undermines global tobacco prevention and control interventions, particularly with respect to tobacco tax policy. From a public health perspective, illicit trade weakens the effect of tobacco excise taxes on tobacco consumption - and consequently on preventable morbidity and mortality - by increasing the affordability, attractiveness, and/or availability of tobacco products. Furthermore, tobacco illicit trade often depends on and can contribute to weakened governance.

The key to resilient housing lies in the fine print

From Canada to Kenya, nearly every country struggles to provide housing for all its residents. It’s a goal that has become a moving target: Migration – both rural-to-urban and cross-border – is placing mounting pressure on cities to house their newcomers.

Three million people move to urban areas every week, and by 2030, three billion more people will need quality housing. The growing risks of climate change demand housing strategies that focus not only on affordability, but also on resilience.

As markets change fast, governments must be ever vigilant that policies don’t become obsolescent or even harmful because their details have become out of date. Even well-designed housing programs require adjustments.

Medellin Lab 2.0: Sharing knowledge on urban transformation

Philip E. Karp's picture
 


Medellin represents a remarkable story of urban transformation. 
 
At one point, it was considered one of the most dangerous cities in the world. From 1990 to 1993, more than 6,000 people were murdered annually.  Drive-by shootings were regular and indiscriminate, stemming from warfare between gang lords, drug criminals, and para-military groups.  The need for change was urgent and led to radical urban experimentation.
 
The city’s political and business leaders recognized that Medellín’s security issues could not be dealt with through policy measures alone. They initiated a series of radical programs to reshape the social fabric of the city’s neighborhoods and to mobilize the poor. 
 
City planners began addressing the problem of endemic violence and inequity through the design of public spaces, transit infrastructure and urban interventions into marginalized neighborhoods.  Key to their approach was a commitment to making the public realm a truly shared space, and a faith that they could transform Medellín’s public spaces from sites of segregation and warfare into spaces where communities would come together. 

Resilient housing joins the machine learning revolution

Machine learning algorithms are excellent at answering “yes” or “no” questions. For example, they can scan huge datasets and correctly tell us: Does this credit card transaction look fraudulent? Is there a cat in this photo?

But it’s not only the simple questions – they can also tackle nuanced and complex questions.

Today, machine learning algorithms can detect over 100 types of cancerous tumors more reliably than a trained human eye. Given this impressive accuracy, we started to wonder: what could machine learning tell us about where people live? In cities that are expanding at breathtaking rates and are at risk from natural disasters, could it warn us that a family’s wall might collapse during an earthquake or rooftop blow away during a hurricane?

Can Wealth Taxation Work in Developing Countries? Guest post by Juliana Londoño-Vélez

Development Impact Guest Blogger's picture

This is the first in this year's series of posts by PhD students on the job market.

Developed countries have recently begun considering wealth taxes to raise revenue and curb rising inequality. Should developing countries follow suit? On the one hand, developing countries are often afflicted by acute income and wealth inequality (Alvaredo et al., 2018), and could thus benefit from a more progressive tax system. On the other hand, the question remains whether governments can enforce wealth taxes on an elite that have a vast arsenal of tools to avoid and evade taxes altogether.

My job market paper explores individual responses to personal wealth taxes and enforcement policies in Colombia. Colombia provides a unique opportunity to study these issues thanks to its extensive administrative tax microdata on the assets and debts of wealthy individuals, its numerous tax policy changes since 2002, and its recent enforcement efforts to improve compliance among the rich.

The challenges of bringing development to the remote areas of Colombia

In 2017-18 we visited the Meta department in Colombia on multiple occasions. Located right where Colombia’s Llanos Orientales (Eastern Plains) disappear south into the vastness of the Amazon rainforest, this area of the size of Belgium, the Netherlands, and Luxembourg combined is a magical spot in the world’s second most biodiverse country.
 
Meta is not a poor region - it boasts some of the nation’s largest oil reserves. Highly fertile soil and multiple thermal floors have created a boom in agribusiness in recent years, while its geographic proximity to Colombia’s capital has more recently led to a thriving tourism industry.
 
Despite having made significant progress on many fronts, this region still faces critical challenges. On our last visit, we had the opportunity to chat for hours with several small-scale farmers from south-western Meta – a sub-region where economic development has been seriously damaged by the cultivation of coca leaf, the raw material used to produce cocaine.
 

Why are energy subsidy reforms so unpopular?

It is well established in the economic literature that it’s the rich who benefit from the lion’s share of energy subsidies. Yet, it is often the poor and vulnerable who protest loudly against these reforms. Why does this happen? What are we missing?

As the World Bank Group strengthens support for refugees, internationally displaced people, and their host communities, the World Bank Art Program curated a multi-dimensional art exhibition entitled, Uprooted: The Resilience of Refugees, Displaced People and Host Communities to contribute a unique perspective. This exhibition showcased the creative voices of those artists touched by the refugee crisis, or those artists who were refugees themselves.

The Uprooted exhibition included a visual art exhibition and musical performances featuring over 30 artists from places such as Bangladesh, Pakistan, Colombia, Lebanon, Iraq, Syria, Jordan, Central African Republic, Burundi, and Guinea. The artists produced works that questioned the impact of transience in individual lives and entire communities of people.

One capstone of the exhibition was the construction of a shed intended to evoke the shelters found in places such as the Azraq Refugee Camp in Jordan. For the exhibition, the shed was enhanced with murals on its sides. Each mural was done by the hand of a different artist – Suhaib Attar, an artist from Jordan and son of Palestinian refugee parents, Marina Jaber from Iraq, a country with millions internally displaced people, Diala Brisly, a refugee from Syria, and Didier Kassai from the Central African Republic, a country in which violence and war have forced hundreds of thousands into displacement.
