Dr. Killian Vos, has announced a new webGIS platform at http://coastsat.space with updated satellite-derived time-series of shoreline change created with hashtag#CoastSat and the hashtag#Landsat archive. This dataset provides insights on coastal dynamics from 1984 to 2024.

The time-series include sandy beaches in hashtag#Australia, hashtag#NewZealand, hashtag#Japan, hashtag#Hawaii, hashtag#California, hashtag#Mexico, hashtag#Peru, hashtag#Chile and US East Coast (hashtag#Deltaware to hashtag#Texas). Dr. Vos has reprocessed them to 2024 and integrated the FES2022 global tide model for better tidal corrections and beach slope estimations. Reach out to him if you have interest in covering new regions or adding new datasets.  Check out this article for more info and use cases around the monitored coastlines:

Dr. Vos welcomes feedback on his new EO coastal platform.

Introductory Webinar: Calculating Spectral Indices for Land and Aquatic Applications Using QGIS

February 27, 2025 11:00-12:30 EST (UTC-5) This training will provide an overview of spectral indices for land and aquatic applications as they are calculated with a QGIS platform. Specifically, this training will begin with an introduction to the Normalized Difference Vegetation Index (NDVI), along with its calculation, uses, and applications in diverse thematic areas (agriculture, disasters, etc.). We will review additional land-based indices such as the Enhanced Vegetation Index (EVI), Soil-Adjusted Vegetation Index (SAVI), and Normalized Burn Ratio (NBR). Finally, we will concentrate on spectral indices primarily used in aquatic ecosystems, such as the Normalized Difference Chlorophyll Index (NDCI), Normalized Difference Aquatic Vegetation Index (NDAVI), Floating Algal Index (FAI), and Normalized Difference Turbidity Index (NDTI) for aquatic applications. Not only will these sessions discuss the correct circumstances under which to use these indices, but participants will also take part in hands-on indices calculation over relevant study areas. Case studies using indices for land and aquatic applications will be highlighted. Register

Webinar Introductorio: Cálculo de Índices Espectrales para Aplicaciones Terrestres y Acuáticas Usando QGIS

Los día 27 de febrero 2025 14h a 15h30m horario este de EE.UU. (UTC-5) Esta capacitación presentará un resumen general de los índices espectrales para aplicaciones terrestres y acuáticas y cómo calcularlos utilizando la plataforma QGIS. La capacitación comenzará con una introducción al Índice de Vegetación de Diferencia Normalizada (Normalized Difference Vegetation Index o NDVI)), junto con su cálculo, usos y aplicaciones en diversas temáticas (agricultura, desastres, etc.). Repasaremos otros índices para aplicaciones terrestres, como el Índice de Vegetación Mejorado (Enhanced Vegetation Index o EVI), el Índice de Vegetación Ajustado al Suelo (Soil-Adjusted Vegetation Index o SAVI) y el Índice Normalizado de Área Quemada (Normalized Burn Ratio o NBR). Por último, nos enfocaremos en los índices espectrales utilizados principalmente en ecosistemas acuáticos, como el Índice de Clorofila de Diferencia Normalizada (Normalized Difference Chlorophyll Index o NDCI), el Índice de Vegetación Acuática de Diferencia Normalizada (Normalized Difference Aquatic Vegetation Index o NDAVI), el Índice de Algas Flotantes (Floating Algae Index o FAI) y el Índice de Turbidez de Diferencia Normalizada (Normalized Difference Turbidity Index o NDTI) para aplicaciones acuáticas. Se discutirán las circunstancias correctas para utilizar estos índices y los participantes también participarán en cálculo de estos índices sobre áreas de estudio relevantes. Se destacarán estudios de caso que utilicen índices para aplicaciones terrestres y acuáticas. Registrarse

Join UNESCO for the first webinar in this series: “Water Quality and the Global Goals for Sustainability” by Dr. Joseph Alcamo, University of Sussex (UK)

UNESCO is pleased to announce the launch of our Monthly Webinar Series commemorating the UNESCO Intergovernmental Hydrological Programme’s 50th anniversary and 60 years of water sciences at UNESCO.

This comprehensive series, “Frontiers of Global Water Science,” brings together distinguished experts from the UNESCO Water Family and their international partners for in-depth discussions on critical water challenges and innovations.

Join the webinar on 30 January, 2025 from 13:00 to 14:00 (CET) featuring Dr. Joseph Alcamo (University of Sussex) on “Water Quality and the Global Goals for Sustainability.” Using the WorldQual model, Prof. Alcamo will present findings on river pollution across three continents, showing how bacterial contamination affects one-third of river-kilometers and impacts public health. He will also explore ecological solutions and management approaches for developing countries, highlighting science’s role in addressing these challenges.

Joseph Alcamo is Professor of Environmental Systems Science at the University of Sussex and Director of the Sussex Sustainability Research Programme (SSRP). His extensive experience in environmental systems science and dedication to sustainable development make him an ideal speaker to kick off our series. The presentation will be followed by a 15-minute Q&A session where participants can engage directly with Prof. Alcamo.

Throughout 2025, these monthly webinars will promote knowledge exchange and strengthen collaborations within our global water science community.

Register for the first webinar here:https://unesco-org.zoom.us/webinar/register/WN_1puvdSGVTo6L3JJIBaJfTA

The complete programme schedule will be available shortly on the UNESCO IHP website.  Join UNESCO in advancing water science for sustainable development.
