Rain Is Coming to Burning Los Angeles and Will Bring Its Own Risks
Rain is forecast to begin as soon as Saturday afternoon and to continue as late as Monday evening, says meteorologist Kristan Lund of the National Weather Service’s Los Angeles office. The area desperately needs the precipitation, but experts are warily monitoring the situation because rain poses its own risks in recently burned areas— most notably the potential occurrence of mudslides and similar hazards. “Rain is good because we’ve been so dry,” Lund says. “However, if we get heavier rain rates or we get the thunderstorms, it’s actually a lot more dangerous because you can get debris flows.”
Fires do a couple of different things to the landscape that can increase the risk of burned material, soil and detritus hurtling out of control. When fires burn hot or long enough, they leave an invisible layer of waxy material just under the surface of the ground. This develops from decomposing leaves and other organic material, which contain naturally hydrophobic or water-repellent compounds. Fire can vaporize this litter, and the resulting gas seeps into the upper soil—where it quickly cools and condenses, forming the slippery layer.
When rain falls on ground that has been affected by this phenomenon, it can’t sink beyond the hydrophobic layer— so the water flows away, often hauling debris with it. “All of the trees, branches, everything that’s been burned—unfortunately, if it rains, that stuff just floats,” Lund says. “It’s really concerning.” Even a fire that isn’t severe enough to create a hydrophobic layer can still cause debris flows, says Danielle Touma, a climate scientist at the University of Texas at Austin. Under normal conditions, trees and other plants usually trap some rain above the surface, slowing the water’s downward journey. But on freshly burned land there’s much less greenery to interfere; all the rain immediately hits the ground. [...]
Fortunately, the rain should also help firefighters tame the blazes that remain active. The largest, the Palisades Fire, is currently 77 percent contained. The second largest, the Eaton Fire, is 95 percent contained. The Hughes Fire is third largest and only 56 percent contained. A fire can be fully contained but still burning. The containment percentage refers to the amount of the perimeter that has barriers that firefighters expect will prevent further spread.

Many studies reveal the contributions of plant breeding and agronomy to farm productivity and their role in reshaping global diets. However, historical accounts also implicate these sciences in the creation of new problems, from novel disease vulnerabilities propagated through industrial monocrops to the negative ecological and public health consequences of crops dependent on chemical inputs and industrialized food systems more generally.
Increasingly, historical analyses also highlight the expertise variously usurped, overlooked, abandoned, or suppressed in the pursuit of “modern” agricultural science. Experiment stations and “improved” plants were instruments of colonialism, means of controlling lands and lives of peoples typically labeled as “primitive” and “backward” by imperial authorities. In many cases, the assumptions of colonial improvers persisted in the international development programs that have sought since the mid-20th century to deliver “modern” science to farming communities in the Global South.
Awareness of these issues has brought alternative domains of crop science such as agroecology to the fore in recent decades, as researchers reconcile the need for robust crop knowledge and know-how with the imperatives of addressing social and environmental injustice.

Excerpt:
"Implementing technology in the language classroom can foster learner autonomy, yet it demands careful planning and ongoing assessment to ensure meaningful interaction. Teachers should integrate digital resources that reinforce communicative goals rather than simply replacing traditional methods."
