🚨À ne pas manquer : Le secret des eaux souterraines dévoilé en LIVE🚨
Qui se cache derrière nos réserves d'eau🚿? Jean-Denis Taupin lève le voile lors d'un live exceptionnel! Vous y croyez❓ Moi, aussi je n'y croyais pas avant de découvrir le monde fascinant des eaux souterraines🌊
"Nous ne connaissons la valeur de l'eau que lorsque le puits est à sec." - Proverbe anglais

2/6: Loss of #biodiversity is one of the most devastating impacts of #climatechange as it compounds the damages to our ecosystems, agriculture, and livelihoods.
3/6: As the planet’s atmospheric temperature continues to rise, extreme weather events become more frequent, and ecosystems, to face further destruction, we drive loss of species, sometimes with irreversible consequences.
1/29. 📜NEW BRIEF: Today we launch “PASSED THE POINT OF NO RETURN: A Non-Economic #LossAndDamage (#NELD) Explainer” covering what #NELD is, why and how it happens, where it happens, who is most affected, and importantly, how we can respond.

2/29. The brief begins with a foreword by @UNFCCC NELs Expert Group Member @IrfanUllahCDO, who highlights that Non-Economic #LossAndDamage has been largely overlooked in climate negotiations and that urgent action is needed to address #NELD happening now e.g. The #PakistanFloods.
3/29. Then @DLodry of @LossDamageYouth shares the powerful story of his lived experience of Non-Economic #LossAndDamage in #Cameroon called "The Tears Of A Village River And Its Population" which tells how climate-intensified #Drought can lead to a loss of #Culture and #Identity.

1/8 Our paper in a #nutshell 🌰The prevailing view is that dryland areas like the Sahara or Sahel are largely free of trees and shrubs 🌴🌳. However, we find that’s not the case!😯🤓🤖the relatively high density of isolated trees challenges prevailing narratives #desertification
2/8 Although the overall canopy cover is low, the relatively high density of isolated trees challenges prevailing narratives about dryland desertification (see photo below) 🌴👉
In IPES-Food's latest report, 'The Added Value(s) of #Agroecology', we focused on a series of obstacles that prevent the transition to agroecological #foodsystems.
🌱 One such obstacle is the *access to #seeds & #organic inputs*. Here's a quick thread on why this matters! 👇🏿

#Farmer seed systems - through which farmers select, multiply, conserve & exchange a wide range of reproducible varieties - are an essential component of #agroecology, which relies on diversity at all levels (including crop genetic diversity). 🌱🌿🌾

#DidYouKnow that these systems account for up to 90% of the seeds used in some African countries? And in #Mali, peasant seed systems make up 75% of the varieties grown in the country.
❗️ However, these systems are lacking in legal recognition and policy support ❗️

At a press conference on the #GreatGreenWall in the #Sahel and #Sahara
Deputy Secretary-General of the @UN @AminaJMohammed says it is vital to complete the wall. "The #GreatGreenWall provides solutions to properly respond and recover from the current challenges."
Deputy Secretary-General of the @UN @AminaJMohammed says it is vital to complete the wall. "The #GreatGreenWall provides solutions to properly respond and recover from the current challenges."
The #GreatGreenWall is meant to tackle climate change, land degradation, and loss of biodiversity in the #Sahel and #Sahara from Senegal to Djibouti. 65% of African land is currently degraded. #ClimateChange #desertification
Close to 18 million hectares of land have been restored by the #GreatGreenWall. The target is 100 million hectares by 2030. In an update today, @UNCCD says 8,2 million hectares & $4.3 billion are needed to reach the goal.
At a @UNCCD press conference on the Great Green Wall for the Sahara. The GGW aims to create a 15km wide and 8,000 km long green corridor stretching across Africa from Senegal to Djibouti to combat #desertification. Desertification is a significant challenge in the region.
"We need to move forward and help the local populations," @greatgreenwallafrica ambassador @Innamodja said. #climatechange #desertification
The goal is for the GGW to be complete by 2030.
Q: Will the Great Green Wall be completed by 2030?
A from Louis Perroy from @climatekos : "It is an extremely challenging target. If we carry on having the same security issues, it will be a challenge." #ClimateChange @UNCCD

My first 2 months at @EU_ScienceHub have been fascinating. I’ve begun to explore a rich tradition of scientific excellence spanning nearly 60 years.
Here are some of the things I have discovered so far ⬇️

On August 7, 2019, the @IPCC_CH published Climate Change and Land, a special report that addresses greenhouse #gas emissions and their link to #desertification, #land degradation and #food #security.
This report is the culmination of two years of work by 107 experts from 52 countries. The report is a key scientific input at the Conference of the Parties of the #UN Convention to Combat Desertification (COP14) in New Delhi this month. ruralindiaonline.org/library/resour…
About 1/4th of the Earth’s ice-free land area is subject to human-induced degradation that is an adverse land condition caused directly/indirectly by humans, leading to a long-term reduction in/ loss of,the land’s biological productivity,ecological integrity, or value to humans.
