Have you suffered heat stress this summer? If not, you were lucky. Depending on where you live and how wealthy you are, a sweltering and humid couple of days can either be an opportunity to catch up with paperwork in an air-conditioned room, or they can literally mean the difference between life and death. Too much heat can kill you.
Accumulated scientific evidence shows that proper nutrition and stimulation in utero and during early childhood benefit physical and mental well-being later in life and contribute to the development of children’s cognitive and socioemotional skills. Yet, a critical but often overlooked fact in policy design and program development across the world is the association between maternal depression and childhood stunting -- the impaired growth and development measured by low height-for-age.

Cities are growing at a staggering rate, changing our world beyond recognition. For the first time in history, over half the population -- 55 percent -- lives in urban areas. By 2050, that number will rise to 68 percent. This rapid urban growth has given rise to sprawling megacities, many of which are in Asia and Africa.
Perhaps no place epitomizes this trend better than Shanghai. In 1990, the city was still primarily an industrial hub with a population of 13 million. By 2016, the figure had ballooned to 24 million, making Shanghai one of the largest metropolitan areas in the world and the financial and economic hub of China.
As an urban dweller in Beijing, a rapidly modernizing city, my daily life would look like a science-fiction movie for people from just a few decades ago. I use my mobile phone to buy groceries, pay for meals, take photos, access the subway, and find my way to unknown places.
Cooking with firewood was not only a tough job because of all the smoke but also required skills and experience. If the fire was not well controlled, the rice could be easily burned. .
However, not everyone is as lucky as me.
Water scarcity is a pervasive problem across much of China. By the numbers, per capita water resources stand at only 2,100 cubic meters, which is one-fourth of the global average. Population growth, agricultural demands, and the adverse impacts of climate change further compound the challenge.
As China moves to secure water for all and provide a foundation for continued sustainable social, economic, and environmental development, there are many important lessons that have global relevance and application.
The North Atlantic hurricane season officially opens June 1, and there are predictions that storms this year could be worse than average again. That would be bad since last year was the costliest year on record for coastal storms. Communities and countries across the Caribbean and SE USA were particularly hard hit. The need for resilient solutions to reduce these risks is paramount.
Nonetheless it has been difficult to convince most governments and businesses (e.g., insurance, hotels) to invest in these natural defenses in the absence of rigorous valuations of these benefits.
So in 2016 The Nature Conservancy teamed with the World Bank and scientists from the public, private and academic sectors to identify how to rigorously value the flood protection benefits from coastal habitats. In short, we recommended that we value this ecosystem service by adopting tools and from the engineering, risk and insurance sectors and following an Expected Damage Function (EDF) approach. This approach assesses the difference in flooding and flood damages with and without coastal habitats such as mangroves across the entire storm frequency distribution (e.g., 1-in-10, -25 and -100 year storms).
As the world urbanizes rapidly, – it is estimated that only 1.5% of the world’s land is home to about half of global production.
Such economic concentration is a built-in feature of human settlement development and a key driver of growth. However, while some countries have succeeded in spreading economic benefits to most of their citizens, many other countries have not.
Especially outside the economic centers that concentrate production, there are “lagging areas” with persistent disparities in living standards and a lack of access to basic services and economic opportunities.
Over one billion people live in underserved slums with many disparities from the rest of the city in terms of access to infrastructure and services, tenure security, and vulnerability to disaster risk. A further one billion people live in underdeveloped areas with few job opportunities and public services.
How can countries address the division between the leading and lagging regions?
