What a fantastic review by @westsyduhie.bsky.social researchers on the impacts of climate extremes on plant pathogens, microbiomes and plant health.

despite an increase in N2O emissions after the termination of the #covercrops, and without significant change in #yield
#cassava can be cultivated in a much more sustainable way for #soils, #climate, and #foodsecurity
The previous study about SOC stock changes:
soil.copernicus.org/articles/10/...
Using measured change in SOC stocks with a diachonic method (10 yrs) and equivalent soil mass, we also calculated changes in #carbondioxide and the overall #greenhousegas balance. We showed that cassava grown under #conservationagriculture resulted in a large net climate mitigation benefit,
#JustOut The second paper of Vira Leng's PhD is finally out, congrats 👏 !! It is #openaccess and available here:
doi.org/10.1016/j.ag...
We monitored #nitrousoxide and #methane emissions during two full years in a long-term experiment in Cambodia, comparing different cassava-based cropping systems.
The current paper is also illustrated by examples taken from the PhD of @souleymanejules.bsky.social in Zimbabwe 🇿🇼, and referring to this paper:

... and how surface albedo affects climate and #climatechange mitigation strategies
The idea of this paper emerged during a workshop hold in December 2020 "Can albedo change offset the climate benefit of carbon sequestrating practices?". All keynote presentations are here:
albedocc.lsce.ipsl.fr
New #openaccess paper "Reflecting on surface albedo and climate". Here, we clarify what is surface #albedo, how it is measured, what influences surface albedo (Earth surface features, soil and plant properties, land use and land management...), ...

With this natural aridity gradient, the #RAIZ Project experiments with farmers a basket of options towards more climate-smart cropping systems, and this is complemented with our on-station rainfall exclusion experiment in Harare. #climatechange #adaptation #foodsecurity #diversification
But this time in a more water-limited environment.
The district is in AgroEcological Zone (AEZ) III (650-800mm, semi-intensive farming) & in AEZ IV (450-650 mm, semi-extensive farming). More droughts and dry spells, more livestock than in Murehwa which is in AEZ II (750-1000mm, intensive farming).
Again, some demonstration plots and trials with #legumes, sorghum, maize, cowpea, mucuna, #intercropping, integrated #soilfertility management. Also more soil profiles, and some serious infestation with witchweed in some plots...
Another day, another district... #RAIZ Project field days in Mutoko! Same success 👏 , same energy, same willingness of farmers, extension officers, scientists and students to share experience and knowledge. Even us scientists learn a lot during these days.
Then an experiment with mucuna grown as a green manure to improve soil fertility, and replicated in about 300 farms, and finally observed soil profiles. #sustainableintensification
Great success for the #RAIZ Project field days in Murehwa 🇿🇼! Congrats to the team for organizing such a very nice event!
We first visited demo plots showing maize 🌽 or sorghum without #fertilizers, with #manure, with both manure and fertilizers, and with or without #intercropping with cowpea.

We analyse current SOC monitoring methodologies for croplands and proposes a decision tree to help MRV stakeholders select the monitoring strategy considered most appropriate for their context
New analysis confirms global warming is accelerating. "all data sources agree: the warming rate has been far higher during the last decade than any previous." agupubs.onlinelibrary.wiley.com/doi/full/10....
Three years after, we came back to the same two paired-sites inside and outside of protection areas in Zimbabwe 🇿🇼 for the 2nd #SoilBON sampling campaign @soilbon.bsky.social ! And this time, instead of #teabags, we also buried wood sticks to study litter decomposition #soilhealth #soilbiodiversity
Illiana Kwenda successfully defended her MPhil "Performance of Maize and Legume Fodder Crops Under Current and Future Climate: A Case Study in Mutoko District, Zimbabwe" @gatienfalconnier.bsky.social
Her first article below, a 2nd one is in the making. Well done Illiana 👏 !

Do we have globally representative data to understand soil processes? We set out to explore this in our Letter that’s in press at Biogeochemistry

Thank you @pablogarciapal.bsky.social ! I will learn a lot in this project, and of course enjoy the amazing biodiversity of Hwange National Park 🇿🇼 #Big5 !
This morning was the online kickoff meeting of the #ELECASE project "ELephants Engineering of dry woodland and consequences for CArbon Sequestration" @agencerecherche.bsky.social
Such an exciting (and challenging) project for the next 5 years 🤩 ! @cirad.bsky.social @cnrs.fr

Researchers have published the recipe for an artificial-intelligence model that reviews the scientific literature better than some major LLMs are able to, and gets the citations correct as often as human experts do

The diversity of soil types, farming systems, tree species in such a small area is really striking. It is actually quite difficult to find a small plot without trees!
It was great to spend time in the field to discuss protocols with colleagues (and enjoying some fresh mangoes 🥭!)
for the PhD thesis of Milton Oboka and of Isaack Hassan Adan from the University of Embu. In the next 3 years, they will study crop and tree productivity, carbon, nitrogen and water cycling, soil biodiversity, pests, pollination...
What a fantastic week in the field in Embu county, Kenya 🇰🇪! We visited many farmers in the 4 wards (Mbeti South, Nthawa, Makima, Mavuria) of the GALILEO EU-AU project @cirad.bsky.social living lab, to identify paired #agroforestry - non agroforesty plots
However, we also found out that integrated soil-fertility management (#ISFM), combining organic and mineral fertilizers, can be seen as a no-regret climate change adaptation strategy, capable of sustaining and substantially increasing yields, even under #climatechange.
In #subSaharanAfrica, #soildegradation threatens #maize yields as much as #climatechange
www.cirad.fr/en/press-are...
We used 4 long-term experiments in sub-Saharan Africa (2 from Kenya, 1 from Côte d'Ivoire, 1 from Zimbabwe) and an ensemble of 15 calibrated soil-crop models to show that hashtag#soilfertility decline over time can impact maize 🌽 yields even more than climate change.
