What was in news last week in the World of Hydroinformatics ?


..."the global water crisis will put half the world’s food production at risk of failure within the next 25 years".

A report from the Global Commission on the Economics of Water warns that over half the world's food production will be at risk of failure within 25 years due to a rapidly accelerating water crisis. The report found that demand for fresh water will outstrip supply by 40% by the end of the decade due to unprecedented stress on the world's water systems. The report also found that governments and experts underestimate the amount of water needed for people to have decent lives, with most regions relying on trade for food, clothing, and consumer goods.

Bangkok will host the International Soil and Water Forum 2024, co-organized by the Food and Agriculture Organisation of the United Nations (FAO) and the Ministry of Agriculture of Thailand, December 9–11, 2024. 

The world's first action plan on halting soil degradation and water scarcity will be discussed at an event featuring heads of state, ministers, researchers, and experts. The campaign, "Caring for Soils: measure, monitor, manage," emphasizes the importance of soil data for agriculture and biodiversity.

The next United Nations Water Conference will be held in 2026 in UAE and cohosted by Senegal and UAE

The 2026 United Nations Water Conference, co-hosted by Senegal and the UAE, will aim to accelerate the implementation of Sustainable Development Goal 6 by ensuring water availability and sustainable management for all. The conference, the first since the launch of the UN System-wide Strategy for Water and Sanitation in July 2024, will focus on enhancing water action and political commitment to address water-related challenges.

The Global Ecosystems Atlas, the first open-source atlas of the world's ecosystems, has been launched at the 2024 United Nations Biodiversity Conference.

The atlas aims to provide a comprehensive and harmonised resource for mapping and monitoring all the world's ecosystems. It will help identify priority areas for conservation and restoration, making it an invaluable resource for policymakers, financial institutions, private companies, and local communities. Monitoring ecosystems will be instrumental in implementing the Kunming-Montreal Global Biodiversity Framework, an international agreement aimed at halting and reversing biodiversity loss by 2030.

"....new research suggests the slowing of a key ocean current could reduce projected Arctic warming by up to 2 degrees Celsius by the end of the century."

New research suggests that the slowing of the Atlantic Meridional Overturning Circulation (AMOC) could reduce projected Arctic warming by up to 2 degrees Celsius by the end of the century. The AMOC is a critical component of the climate system, as it moves heat around the globe. The study, published in the Proceedings of the National Academy of Sciences, examined the effects of the slowing AMOC on the Arctic climate. Although temperatures in the Arctic are projected to rise by 10 degrees Celsius by the end of the century, when the slowing AMOC current is factored in, Arctic temperatures will only rise by 8 degrees Celsius.

However, the study also highlights ongoing concerns for Arctic ecosystems, such as habitat loss for polar bears and the potential shift in the Intertropical Convergence Zone, a tropical rain belt. The overall impact on ecosystems and weather patterns, both in the Arctic and globally, could still be severe. The research team used a coupled climate model to isolate the effect of the AMOC by running two simulations.

Eight most common impurities observed in water supplied to domestic households

The water supplied to domestic households has many types of contaminants which have the potential to create health irregularities in the consumer family. Among these contaminants, eight most common impurities were identified, and the type of filter which can remove or reduce them was delineated in the figure. Before procuring a water filter remember to see this chart. It will help to understand the impurities that the selected water filter can remove. Any water filters available in the market are generally made of one or more of these filters. To decide wisely use the concepts of MCDM to select your filters. Compare the filters available in the market with respect to Cost, Contaminant Removal Efficiency, Maintenance requirement, and type of filters used and rate each filter based on these factors with the help of AHP or ANP techniques. The result will be the filter that will be most efficient for your use. You can also use the ODM tool to come to a decision regarding the procurement o...

How to use Goodrich Flood Routing Method for Predicting Outflow Hydrograph of a Reservoir ?

A mathematical method called the Goodrich Method of Flood Routing is used to forecast how much water would flow through a river or channel during a flood. When determining the downstream water flow rate, the channel's geometry, roughness, and slope are all considered. With the use of this technique, hydrologists and engineers can better evaluate the possible effects of flooding and decide how best to safeguard infrastructure and populations. It makes more precise flood prevention measures possible by properly predicting the behaviour of water under different situations. In order to better inform strategies for sustainable development, the Goodrich Method also evaluates how land use patterns affect the likelihood of flooding. It is a flexible tool for planning for and responding to disasters.

Five open source free hydrologic models that you can use to model runoff of micro to macro watersheds

The principal objective of hydrologic models is to forecast the runoff of a surface water body, especially dendritic systems like rivers, streams, etc. The inputs to these models are generally Rainfall/Precipitation, Soil Characteristics, and other Climatic parameters like evapotranspiration, humidity, etc. LULC and geo-morphology are also used as the required input parameters of the hydrologic models. Both input and output of these models are temporally as well as spatially variable. Now the resolution varies with different models. Some models consider all the sub-basins to be a single watershed and determine the output based on the characteristics of this single watershed(lumped).In contrast, some other models will consider the {impact|effect} of each of the sub-basins on the central outflow of the watershed(distributed).In a few models, the entire watershed is divided into grids or units of uniform dimension. However, the accuracy is highest for the models, which considers the {impa...
