Bangladesh’s rice farmers tap underground ‘reservoirs’

[NEW DELHI] The pumping up of groundwater by Bangladesh’s 16 million smallholder farmers has led to a massive storage capture of underground reservoirs rivalling the storage capacity of the world’s large dams, according to a study . Published in   Science,   the   study   said that groundwater-fed irrigation had transformed much of Bangladesh’s single-crop, rain-watered floodplains into highly productive double-cropping and, in places, triple-cropping lands to make the country the world’s fourth highest producer of rice. The researchers say the  sustainable  irrigation process could be replicated in other areas affected by the impacts of  climate change  which is intensifying extreme

How Sri Lanka’s forced organic transition crippled its tea industry

                 From - Mongabay Magazine,                By-     Joanik Bellalou  ,               Edited by - Amal Udawatta,            Tea leaves from the Bluefield tea plantations are handpicked during              weekdays. A lack of fertilizers means fewer trips into the fields for                 the workers, as the tea plants now take longer to grow. Image by                  Joanik Bellalou In April 2021, then-president Gotabaya Rajapaksa abruptly banned imports of chemical fertilizers, pesticides and herbicides, in an attempt to preserve Sri Lanka’s fast-depleting foreign currency reserves. The government sold it as a shift to organic agriculture that would make Sri Lanka the world’s first toxin-free nation, but in the process disregarded warnings by academics and agronomists about the disastrous economic fallout. Several months after the aggressive shift, Sri Lanka’s agricultural output has plummeted by 20%, while farmers, who account for 27% of the country’s workforce, have

The science of drought explained in pictures

  By Helen Briggs, Environment correspondent, Edited by -Amal Udawatta, From all the pictures of parched fields, dusty soil and dried-up reservoirs, it might appear obvious there's a drought. But from a scientific point of view, it's more complicated than that. There's no one definition of drought - it's different depending on whether you look at weather, agriculture or water flow in rivers and streams. And when it comes to declaring an "official" drought, government agencies look at how the long dry spell is affecting food production, water supplies and the environment. That includes how much rivers and streams are shrinking, which puts wildlife and water supplies at risk. They also look at threats to crops and livestock if fields are turned into dust bowls. How water supply is affected One big indicator for drought is hydrology - the flow of water through rivers and the state of the water stored underground in permeable rocks beneath the soil. These are cruc
