Water vapor maps from spaceborne radar: first African experiments.

The prediction of rainfall is a critical issue in several African countries. The scarcity of in-situ measurements (for example from ground-based radars) of water vapor content in the lower troposphere prevents Numerical Weather Prediction Models (NWPM) to reach high accuracy in weather forecasts. In order to compensate for the lack of in-situ measurements, satellite images […]

Mobile phone services for farmers

The limited amount of extension services for farmers. Using traditional farming practices and mostly relying on manual family labor, farmers receive only two extension visits (often at the start of the year and towards the end) due to limited resources and poor road infrastructure to villages. The absence of this timely agricultural information makes it […]

Drone training at KNUST in Kumasi

The recipe for a successful drone training week: 11 motivated participants. 1 Flying Sensor. 1 challenging task to perform. Perfect facilities (Thank you Mr Isaac Duodu from Kumasi Business Incubator!). The right assistance (Mr Joel Budu from Farmerline!). That`s what it takes to perform a week`s training and finish it successfully. Coming from different professional backgrounds […]

FAO AquaCrop in TWIGA

Crop simulation models are widely used by scientists, policy-makers, and practitioners to understand the response of crop yield to variables including soil fertility, water availability, and atmospheric composition. Among crop simulation models a common drawback is the need for highly detailed input data and parameter values, which are rarely available in data-scarce regions such as […]

GNSS DEPLOYMENT IN UGANDA

Objective 4 of the TWIGA project aims to Improve predictability and assessment of African rainfall by mapping perceptible water vapour and tracking convective storm systems. The main reason behind the poor prediction skills of present rainfall forecasts in Africa is the lack of knowledge of precipitable water vapour (PWV) in the atmosphere. If one does […]
