Sydney, 28.06.2021 (IPS): Robby Nena is one of the many farmers and fishermen on the frontline of climate change in the Federated States of Micronesia (FSM), where coastal flooding and erosion, variable and heavy rainfall, increased temperature, droughts and other extreme weather events are becoming all too common.

FSM is one of the 22 Pacific Island Countries and Territories (PICTs). These nations contribute less than 0.03 percent of the world’s total CO2 and other greenhouse gas (GHG) emissions. Yet, they are amongst the most vulnerable to the impacts of global warming, climate change and sea level rise. A quarter of Pacific people live within 1 km of the coast.

“Every time it rains, our home and farm get flooded, destroying our crops, damaging infrastructure and posing a major health hazard. Our tapioca and taro crops were completely destroyed in the major flooding event last month”, Nena tells IPS from Utwe village in FSM’s Kosrae state via a choppy Messenger call.

Sydney, 11.12.20 (SciDev.Net): Researchers have developed a living plant-based sensor that can in real-time detect and monitor levels of arsenic, a highly toxic heavy metal, in the soil. Arsenic pollution is a major threat to humans and ecosystems in many Asia Pacific countries.

Arsenic contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health because the toxic chemical is naturally present at high levels in the groundwater of a number of countries, according to the World Health Organisation (WHO).

“Detecting arsenic level in the soil is important to ensure minimal contamination of our food chain. If we can have a convenient way to measure arsenic concentration in the soil in real time, we would be able to take preventive measures to keep arsenic level at the minimum, strengthening our food safety”, says Tedrick Thomas Salim Lew, a recent graduate student of the Massachusetts Institute of Technology (MIT) and co-lead author of the research published in Advanced Materials on 26th November 2020.

Mohangarh, (Jaisalmer District, Rajasthan, India), 29.03.2012 (The Hindu Businessline): Not long ago, the remote communities in Jaisalmer district eked out a living from a single annual crop of millet (bajra), dependent on the mercy of rain gods. The 48 degree centigrade heat of the harsh summer sun, frequent sandstorms and no water posed a major challenge for survival. Droughts and the spectre of camel and livestock bones strewn on the sand dunes was a common phenomenon. But the advent of the Indira Gandhi Canal Project (IGNP) in the mid-1980s transformed the landscape and its inhabitants.
