Updates on the Collaroy seawall from @wendy_harmer 👇.

This is one of many ways to manage our #coasts & deal with #erosion issues. 🧵[1/5]

Other options include:
1. Do nothing. This is cheap in theory but may have hidden costs due to having to deal with the impacts of erosion.
2. Retreat and relocate. This involves moving infrastructure and property back away from the area of risk and allowing the coast to do its thing in a more natural manner. There are big challenges with how you do this and manage people who own beachfront property.
🧵[2/5] Image
3. Soft engineering solutions. This includes doing things like beach nourishment and rebuilding dunes using "soft" approaches like fences. It has costs and does not provide a hard line beyond which the beach cannot erode.

🙋‍♀️Bonjour, c'est Fatima Jomaa, doctorante à @IGE_Grenoble, qui travaille avec l'équipe C2H (Climat, Cryosphère et Hydrosphère). ⤵️
🔎L'équipe C2H cherche à mieux comprendre les interactions entre le #climat, la cryosphère et l'hydrosphère dans les régions froides de la planète, et leur positionnement dans le système climatique global. Suivez mon fil de discussion pour en savoir plus sur mon travail !🧐
➡️Les risques naturels associés aux précipitations extrêmes, tels que les #inondations 🌊 et l'#érosion côtière, ont provoqué la mort de milliers de personnes et d'énormes pertes économiques. Image

"In September 2020, #Cambodia razed a #US-built facility on #Ream Naval Base that served as the headquarters for the National Committee on Maritime Security, reportedly in order to make way for a #PRC #naval #base."

🚨My first #phd @EarthArXiv #preprint!🚨doi.org/10.31223/X5Q592

"A Storm Hazard Matrix combining coastal flooding and beach erosion"

Consider these two locations. Did they face the same type of coastal storm hazard? A thread 1/7
Coastal #storms and #hurricanes can bring flooding (elevated water levels) and beach #erosion, but how much of each depends the coastal setting and the storm conditions. If we can understand and predict what hazards may threaten a coast, we can better prepare for them. 2/7
Coastal flooding and beach erosion hazards on sandy beaches should be considered separately. We're building off the existing Storm Impact Scale and proposing a new erosion hazard scale which is based on changes to the beach and dune profile. 3/7

En Angleterre, l'#érosion des #sols est aussi présente là ou les sols ne sont pas assez protégés...
Quel est le coût environnemental et économique de cette #érosion des #sols ?

En Pologne, cette photo montre une différence suivant le type de gestion des sols...
Si nous voulons assurer notre sécurité alimentaire demain il faut préserver nos sols. #ErosionSol

Érosion des sols: Processus naturel à l’origine des reliefs et paysages
En agriculture, amincissement de la couche arable d’une parcelle sous l’effet d’un arrachement/entrainement de particules solides par les forces érosives de l’eau, du vent ou les pratiques de travail du sol
3 séquences consécutives dans les processus d’érosion :
1- Détachement ➡️ 2- Déplacement ➡️ 3- Dépôt
= différents modes d’action ou d’atténuation à envisager selon la séquence visée

Healthy #soil sequesters #carbon, promotes the growth of nutrient-dense crops, holds more #water, and fights disease. What #farming practices can get you there? A thread:
Cover crops 🌿 When fields are bare, they're vulnerable to #erosion and #nutrient loss. Planting cover crops protects against this, while also smothering weeds, controlling pests, retaining #water, and enhancing #biodiversity.
Crop rotation 🔄 By refusing to plant the same #crop over and over, #farmers can return nutrients to the #soil without synthetic inputs. Crop rotation also wards off pests and disease, which have a harder time adapting with constantly-changing crops.

Need a quick overview of our new report assessing progress in preparing for the impacts of climate change in #England? Look no further! Read the full report theccc.org.uk/publication/pr…, take a look at our new infographic theccc.org.uk/wp-content/upl… or check out the following #thread
[1/10] Ministers must strengthen policy on adaptation & put resources in place to drive action to prepare for climate impacts in #England. Our report finds that support services/funding have been eroded over past 10yrs & latest National Adaptation Programme is not strong enough.
[2/10] There are many examples of dedicated officials+organisations doing great work to try to build resilience to #climate impacts. But a better, strategic national framework to underpin and drive action on the ground is needed. Piecemeal action does not match the scale of risk.

This month we'll be doubling up on #WomenInScienceWednesday to feature black women in STEM for #BlackHistoryMonth. Today we're featuring Marguerite Williams, the first African American to earn a PhD in geology in the United States. 1/n
Williams completed her BA at @HowardU and then went on to complete her MA at @Columbia and PhD in geology at @CatholicUniv in 1942. Her dissertation work was titled "A history of erosion in the Anacostia drainage basin." 2/n
Throughout her education & academic career, Williams taught at the Miner Teacher's College, now part of the @udc_edu, where she served as Chair of the Division of Geography. She was promoted to full professor after receiving her PhD and also taught at her alma matter @HowardU 3/n
