On March 3rd we will celebrate World Wildlife Day. Adopted by the UN General Assembly in 2013, this day raises awareness of the world’s wild fauna and flora. This year’s theme, "The future of wildlife is in our hands" resonates with those who understand the impact of species loss on the health of ecosystems and human survival.
We are currently in the midst of the sixth, man-made mass extinction of plants and animals. Experts estimate the current loss of species to be between 1,000 and 10,000 times higher than the natural extinction rate. The global Living Planet Index (LPI) shows an overall species decline of 52% between 1970 and 2010. Our increasing demands on nature are driving the two biggest catastrophic threats to species decline- habitat loss and wildlife trade. Habitat loss is a threat to 85% of all species. Exploitation (including poaching and wildlife trade) is the most immediate threat to wildlife populations worldwide.
Illicit trafficking in wildlife is a multifaceted global threat. The problem is particularly acute in Africa, where poaching is leading some charismatic species to the brink of extinction. For example, in 2011 the International Union for Conservation of Nature (IUCN) declared the Western black rhino extinct, largely due to poaching. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Monitoring the Illegal Killing of Elephants (MIKE) program estimated that in the last 5 years, between 22,000 to 25,000 elephants were poached per year across Africa.
Factor Allocation and Growth
A central challenge for developing countries is to promote growth by reducing the misallocation of factors of production—labor, capital and land. While there may not be such a thing as a perfectly efficient factor allocation, evidence shows that there are huge gains in growth from reducing factor misallocation. Growth requires more efficient firms to produce more output and use more factors of production. Our past work has shown that land allocation is barely better than random at best, and probably worse than random in India. Put differently, low productivity firms have better access to land and buildings than high productivity firms. Indeed, land and buildings misallocation appears to be at the root of much of the misallocation of output and it accounts for a large share of the observed differences in output per worker in the manufacturing sector.
During the Ganesh Festival in India, tons of idols representing the elephant-headed god are immersed in the ocean. The paint and other elements used for the making of these idols get blended in the water and pollute and kill the marine life of the bay.
SPROUTS Environment Trust, an environmental NGO in India came up with a very original solution to this problem and their initiative took off:

Waste pickers are the principal actors in reclaiming waste for the recycling industry. Across the world, large numbers of people from low-income and disadvantaged communities make a living collecting and sorting waste, and then selling reclaimed waste through intermediaries to the recycling industry. Where others see trash or garbage, the waste pickers see paper, cardboard, glass, and metal. They are skilled at sorting and bundling different types of waste by color, weight, and end use to sell to the recycling industry. Yet waste pickers are rarely recognized for the important role they play in creating value from the waste generated by others and in contributing to the reduction of carbon emissions.
Fortunately, around the world, waste pickers have been organizing and cities have begun to promote the virtuous circle that comes with integrating waste pickers, the world’s recyclers, into solid waste management.
Brazil was the first country to integrate waste pickers, through their cooperatives, into municipal solid waste management systems and the first to adopt a National Waste Policy, recognizing the contributions of waste pickers and providing a legal framework to enable cooperatives of waste pickers to contract as service providers. The national movement of waste pickers in Brazil was awarded a contract to clean the stadiums during the World Cup.
The PPI database suggests that approximately 40 percent of all projects are valued at less than $50 million, and approximately 25 percent of all projects are less than $25 million (Figure below). However, the database misses out on projects in several emerging sectors at the sub-national level. While non-traditional sectors are captured in country and sub-national databases, few of these databases are readily available in the public domain.
In Dhaka, the capital city of Bangladesh, you cannot miss the slum neighborhoods. More than 5,000 slum communities, accounting for 40 percent of the population, are spread across the city, often located right next to luxury penthouses, hotels, and high-rise office buildings. Most slum dwellers are limited to low-quality housing in precarious areas, often prone to flooding. The limited access to adequate shelter is an important factor that – according to the Economist Intelligence Unit’s 2015 livability rankings – makes Dhaka one of the least livable cities in the world. These communities are among the most neglected in the city in terms of urban policy, planning, and development, although the people who live in the slums make up the lion’s share of the work force, which drives the city’s economy, contributing significantly to the garment and leather industries, construction, waste management, and many other informal sectors.
Living in slums puts enormous social, economic, and financial burdens on households, and it can lead to intergenerational poverty. Many argue that slum dwellers are caught in a poverty trap—that living in slums makes it harder for households to escape poverty. Several slum-related factors contribute to the perpetuation of poverty, including poor health outcomes; an inability to access finance or leverage property assets; and lack of access to basic services. The existence of slums is a symptom of a shortage of affordable housing, the provision of which can be viewed as a valuable goal in its own right and as a critical ingredient in addressing the broader challenges of poverty.
We've just launched a new, pilot global subnational population database featuring time series population estimates for 75 countries at the first-level administrative divisions (provinces, states, or regions). The database has time series data that spans 15 years (2000-2014), with total population numbers for each area and the shares relative to total national population estimates.
What's new about this?
The common data source of population estimates for most countries is a census, often conducted every 10 years or so. Many countries publish annual estimates between census years, but few publish similar population estimates for subnational regions. This database aims to provide intercensal estimates using a standard methodology.
