The CZO M-TROPICS (Multiscale TROPIcal CatchmentS) investigates the response of tropical catchments to global change based on long-term collection of meteorological, hydrological, sedimentary, geochemical, and land use data in partnership with academic and governmental institutions in various tropical countries. M-TROPICS includes in particular the experimental watersheds of Nyong in Cameroon (1994-), Houay Pano in Lao PDR (1998-), and of Mule Hole in India (2003-), which encompass a wide gradient of climates, bedrock types, topographies, and land-use conditions.

The datasets are published open access on the M-TROPICS website (https://mtropics.obs-mip.fr/catalogue-m-tropics/) and were the topic of three data notes published in the special issue « Research and Observatory Catchments: the Legacy and the Future » of the Hydrological Processes journal:

Data note for Nyong, Cameroon

Data note for Houay Pano, Lao PDR

Data note for Mule Hole, India

Exploring the nexus between hydroclimatic variability, population growth, land use land cover change, and long-term upper Nyong Basin River chemistry (Central Africa rainforest)

Hydrological and hydrogeochemical functioning of rivers depends on the relationship between climatic variability, land use and land cover change (LULCC), and population dynamics. However, there is a scientific gap on this relationship in the humid tropical zone of Central Africa. This study, led by David Eric Komba, aims to fill this gap by examining the […]

A float-controlled self-contained laser gauge for monitoring river levels in tropical environments

In this paper Dr Pierret and colleagues present the design, construction and performance of a self-contained float-controlled water level gauge for monitoring water levels in streams and small rivers. This device is inexpensive (cost of about EUR 220), easy to build (no electronics skills or specialized tools required; assembled in a few hours) and straightforward […]

Reuse of bottom sediment from reservoirs to cropland is a promising agroecological practice that must be rationalized

In semi-arid areas, intermittent streams are often equipped with small reservoirs to store water for irrigation and/or groundwater recharge, and to capture sediments lost through erosion. These reservoirs must be periodically desilted to maintain their storage capacity. While bottom sediments are generally considered waste, their reuse in agricultural fields is a centuries-old practice in India. […]
