When soil behaves like a liquid it can lose its ability to support structures. The soil can even flow down very gentle slopes, and erupt to the ground surface to form sand boils (“sand volcanoes”).

GHISA Crop Type Map
The DESIS and PRISMA Derived Spectral Library of Agricultural Crops in California was developed using 2020 DESIS and PRISMA data for almonds, corn, cotton, grapes, pistachios, rice, and tomatoes. For more details, see “New Generation Hyperspectral Sensors DESIS and PRISMA Provide Improved Agricultural Crop Classifications” (DOI: 10.14358/PERS.22-00039R2)

Re-greening a Dryland Watershed
The installation of thousands of rock detention structures in the Turkey Pen Watershed, of the Chiricahua Mountains in SE Arizona, provided a 30-year case study to consider low-tech and low-cost Natural Infrastructure in dryland watersheds.

La encrucijada del fuego silvestre
La relación entre la gente y los incendios forestales siempre ha sido paradójica: el fuego es esencial como proceso ecológico y herramienta de gestión, pero también puede ser perjudicial para la vida y la propiedad.

Wildfire at the Crossroads
The relationship between people and wildfire has always been paradoxical: fire is an essential ecological process and management tool but can also be detrimental to life and property. Consequently, fire regimes have been modified throughout history through both intentional burning to promote benefits and active suppression to reduce risks.
