Short summary
Urban gullies are a major problem in Kinshasa, caused by poor planning, fragile soils, and heavy rainfall. They destroy homes, disrupt services, and reduce land value, increasing poverty. A study of 802 households near 183 gullies and 12 brokers shows severe damage and high costs, with property losses estimated at 979 million dollars. Many people underestimate risks, and local solutions are often ineffective, highlighting the urgent need for better planning, prevention and coordinated action.

Pedotransfer functions (PTFs) are used to predict parameters of models describing the hydraulic properties of soils. The appropriateness of these predictions critically relies on the nature of the datasets for training the PTFs and the physical comprehensiveness of the models. This roadmap paper is addressed to PTF developers and users and critically reflects the utility and future of PTFs. To this end, we present a manifesto aiming at a paradigm shift in PTF research.

Measurements of soil water retention properties play an important role in a variety of societal issues that depend on soil water conditions. However, there is little concern about the consistency of these measurements between laboratories. We conducted an interlaboratory comparison to assess the reproducibility of the measurement of the soil water retention curve. Results highlight the need to harmonize and standardize procedures to improve the description of unsaturated processes in soils.

This research highlights the importance of human activities on the occurrence of landslides and the need to consider this context when studying hillslope instability patterns in regions under anthropogenic pressure. Also, this study highlights the importance of considering the timing of landslides and hence the added value of using historical information for compiling an inventory.

Short summary
Heavy rainfall can cause sudden, damaging floods on farmland, yet most small catchments have no stream gauges, making floods hard to predict. We built a detailed computer model that traces how rain becomes runoff across a well-monitored Belgian farm catchment. It reproduces flood timing reasonably well, but less so for short, intense storms. Applied to extreme rainfall scenarios, it pinpoints flood-prone flow paths, a first step toward better flood planning in unmonitored farmland.
