卫星数据使用方法和机器学习方法能够很好地洞悉大数据和新的分析方法今后将如何改变我们度量贫困的方式。我本人并非贫困问题专家,不过我在寻思,这些数据和方法能否帮助我们测算就业增长情况。 
 
研究人员采用机器学习方法(即采用演算法从数据中获得启示)和卫星影像对贫困人口分布情况进行预测。 组合使用卫星影像的时间序列数据和学习辨认建筑物、道路、车辆以及经济活动痕迹的计算机,可带来更准确、成本更低以及更便于推广的方法,用于测算消费支出、资产及财富。图说收入增长情况。  
 

Partners in Prediction: How international collaboration has changed the landscape of hydromet

Intense drought can devastate a country. Severe flooding can be catastrophic. Dealing with both at the same time? That’s just another day for too many countries around the world that struggle to accurately predict weather- and climate-related disasters while simultaneously dealing with their effects.
 
Today, World Meteorological Day recognizes the benefits of accurate forecasting and improved delivery of hydromet services for the safety of lives and economies. Hydrological and meteorological (or “hydromet”) hazards – weather, water, and climate extremes – are responsible for 90 percent of total disaster losses worldwide. Getting accurate, timely predictions of these hazards into the hands of decision-makers and the public can save lives, while generating at least three dollars’ worth of socio-economic benefits for every one dollar invested in weather and climate services – a win-win. But less than 15 years ago, even the small amount of hydromet investment that existed was fragmented, with little hope of producing sustainable results. 

Connecting pension funds with emerging market infrastructure

It might sound improbable to hear a CFO say this, but I consider one of my roles since joining the World Bank Group to be that of matchmaker. Let me explain.

As I have noted in other blogs over recent months, the world’s emerging market and developing economies—EMDEs for short—face an enormous gap in infrastructure investment. Certainly it is not the only big financing challenge that countries face as they work to reduce poverty and extend prosperity to more of their citizens. But infrastructure underpins many aspects of economic growth, getting people to jobs and schools, connecting goods to markets, reducing the isolation of the poorest areas in many countries.  And by some estimates, the sector’s funding gap is as high as a trillion dollars. 

Honoring (and learning from) leaders who make a difference

What kind of leader can bring people together for the common good, even amid clashing opinions or real conflict?

That question was at the heart of the 2017 Global Leadership Forum March 6 on the growing need for “collaborative leadership” in an age of increasingly polarized societies.

The event at the World Bank was organized with the Global Partnership for Collaborative Leadership in Development. It explored how to bridge often wide divides to arrive at inclusive solutions, and featured guests such as Festus G. Magae, a former President of Botswana and a South Sudan peace negotiator, and Frank Pearl Gonzalez, Chief Negotiator in the Colombian Peace Talks.

The youth from the Turia community celebrating their first workshop on tiger conservation in the Pench Tiger Reserve
The youth from the Turia community celebrating their first workshop on tiger conservation in the Pench Tiger Reserve

In 2010, 15 days after graduating from college, with nothing but a backpack and an old water bottle, I stood in front of a large gate with a rusted sign welcoming me to the “Pench Tiger Reserve.” The same reserve that inspired Rudyard Kipling’s, Jungle Book. None of the mock interviews  or standardized testscould have prepared me for the job at hand. I was there to set up a small nonprofit whose mission was to involve youth from the local community near the tiger reserve and instill in them a love and passion for the environment. Specifically, instill in these young minds a commitment to safeguard the 41 tigers that roamed wild in the reserve.

As a 21 year old, my employers were entrusting upon me this responsibility based on a simple philosophy – if you want to inspire young people – give the opportunity to someone young! In the two and a half years that I spent in the reserve, with the help of the forest department, three local schools and community members, we were able to invite leading conservationists, teachers, innovators and environmental enthusiasts to conduct hands-on workshops with children aged 10-16 from within the community. Every workshop answered questions on the importance of environmental protection and the rationale behind how simple, local efforts can have positive impacts globally. These curious minds absorbed knowledge like sponges and within a few years, we had the next set of forest protectors and tiger champions. They are influencers in the community and are currently involved in small enterprises that help the local economy and preserve the tiger habitat in and around the Pench Tiger Reserve.

Since leaving the Reserve, I have been active in many youth groups around the world. One such organization is the 2041 Foundation whose mission is to provide leadership training to young people especially from developing countries to help preserve the environment. As a part of this training, on an expedition to Antarctica, I was able to see firsthand the effects of climate change on our fragile ecosystems. This experience had a profound influence on my commitment to conservation.  

To fight discrimination, we need to fill the LGBTI data gap

Ede Ijjasz-Vasquez's picture
Despite some progress in the past two decades, lesbian, gay, bisexual, transgender, and intersex (LGBTI) people continue to face widespread discrimination and exclusion around the world. Many of them suffer from punitive laws and policies, social stigma, and even violence. They may also be subject to lower educational attainment, higher unemployment rates, poorer health outcomes, as well as unequal access to housing, finance, and social services. As a result, LGBTI people are likely overrepresented in the bottom 40% of the population.
 
The adverse impacts on the health and economic wellbeing of LGBTI groups—as well as on economies and societies at large—tell us one thing: exclusion and discrimination based on sexual orientation and gender identity (SOGI) is a serious development issue.

We’ve already taken the first steps to address this issue, such as quantifying the loss in productivity, but there is still a long way to go. Robust, quantitative data on differential development experiences and outcomes of LGBTI people is crucial, but remains scarce especially in developing countries. Such a research and data gap poses a major constraint in designing and implementing more inclusive programs and policies.
 
The World Bank’s SOGI Task Force—consisting of representatives from various global practices and country offices, the Gender Cross-cutting Solution Area, as well as the GLOBE staff resource group—has identified the need for quantitative data on LGBTI as a priority. 
 
On Zero Discrimination Day, the World Bank’s Senior Director Ede Ijjasz-Vasquez and SOGI Advisor Clifton Cortez explain the urgent need to fill the LGBTI data gap. They’ve also discussed why inclusion matters for development, as well as what can be done to end poverty and inequality for LGBTI and other excluded groups.
