Night falls in Dhaka. Commercial streets glow with lights and the neon-lit stores and restaurants are abuzz with shoppers enjoying a break from Ramadan. This is a great visual spectacle punctuated by the incessant honking of colorful rickshaws.
But the reality is different right outside the capital. Sunset brings life to a halt in rural areas as about 60 percent of rural households do not have access to grid electricity. Kerosene lamps and battery-powered torches are widespread yet limited alternatives, their dim light offering limited options for cooking, reading or doing homework.
It is a sweltering hot day when our team sets out to visit a household of 14 in the village of Pachua, a two-hour drive from Dhaka. Around 80% of the villagers have benefited from the solar panel systems to access electricity. The Rural Electrification and Renewable Energy Development Project (RERED), supports installation of solar home systems and aims to increase access to clean energy in rural Bangladesh.
We’re accompanied by Nazmul Haque Faisal from IDCOL, a government-owned financing institution, which implements the program. “This is the fastest-growing solar home system in the world,” Faisal says enthusiastically, “and with 40,000-50,000 new installations per month, the project is in high demand.”
We’ve now reached our destination and Monjil Mian welcomes us to his house, which he shares with 13 other members of his family, including his brothers, two of them currently away for extended work stints in Saudi Arabia.
Delta regions constitute only 5% of the land area but are home to more than 500 million people. The proportion of deltas susceptible to flooding is projected to further increase, thus affecting negatively the livelihoods of local populations, in particular farmer communities.
Recently, the International Council for Science (ICSU) endorsed the Global Sustainable Deltas Initiative (SD2015). The objective of this initiative is to bring attention to the importance and vulnerabilities of delta regions worldwide. To this aim, the University of Minnesota-led Belmont Forum DELTAS project is working to create a global vision for deltas through scientific integration, collection and sharing of data and stakeholder engagement.
Goals (SDGs), now is the time to consider these delta specific challenges in a broader context.
Deltas are often described as cradles of civilization. They are the testing grounds for early agriculture and the birthplace of hydraulic engineering as we attempted to shape the landscape to suit our needs.
Deltas are the unique result of the interaction of rivers and tidal processes resulting in the largest sedimentary deposits in the world. Although comprising only 5% of the land area, deltas have up to 10 times higher than average population—a number, which is increasing rapidly, especially for deltas in Asia.
Low lying, deltas are widely recognized as highly vulnerable to the impacts of climate change, particularly sea-level rise and changes in runoff, as well as being subject to stresses imposed by human modification of catchment and delta plain land use.
It is Day Ten since the earthquake struck Nepal and the scale of the devastation is only just becoming evident. The official death toll has now crossed 7,000, of which 5,000 have been confirmed in remote rural areas. As many as 15,000 people are injured, many critically. Aftershocks continue to rattle central Nepal and most people are still too jittery to come to terms with what has happened.

While many impacts of climate change are already evident around the world, the worse is still to come. Having a clear picture of future risks is essential to spur action now on a scale that matches the problem. The World Bank has prepared the following infographic to communicate the risks for one of the world’s most vulnerable countries—Bangladesh.
The data comes from the 2013 World Bank report Turn Down the Heat: Climate Extremes, Regional Impacts, and the Case for Resilience. This report combines a literature review and original scientific modeling to build on a previous effort that found that the world will become 4°C (7.2°F) hotter during this century in the absence of deep and fast cuts to global carbon emissions. In this scenario, hotter local temperatures, greater water challenges, higher cyclone risks, and lower crop yields will create a hotspot of risks for Bangladesh.
Bangladesh already has a hot climate, with summer temperatures that can hit 45°C. Heat waves will break new records in a 4°C hotter world, with 7 out of 10 summers being abnormally hot. Northern Bangladesh will shift to a new climatic regime, with temperatures above any levels seen in the past 100 years and monthly deviations five to six times beyond the standard.
