Railway transportation is crucial to reducing greenhouse gas emissions and meeting increasing global demand for passenger and freight transport. To maintain a reliable, high-capacity railway infrastructure, regular and accurate maintenance is necessary. The recent development of a Rail-based Track
Surveying System that can be mounted on any operatio...
Low-cost dual-frequency global navigation satellite system (GNSS) receivers have recently been tested in various positioning applications. Considering that these sensors can now provide high positioning accuracy at a lower cost, they can be considered an alternative to high-quality geodetic GNSS devices. The main objectives of this work were to ana...
Most cadastral systems today are coordinate-based and contain only a weak or no reference to measurements or the origin of the information. In some contexts, this is largely due to the transition of land data management and maintenance from an analogue to a digital environment. This study focuses on analysing the importance of the measurement-based...

As a boundary of the seashore, the high-water mark (HWM) is relevant to the public, the State, and other rights holders in the coastal zone. Unlike most fixed property boundaries that are surveyed and beaconed, the HWM is subject to dynamic natural coastal processes and moves over time. Its location is difficult to determine, and the precision of t...
Echosounders are used to monitor suspended sediment concentrations (SSC) in coastal management studies and to monitor dredge plumes. Due to the dependency on sediment properties like particle size, shape and density, performance of single frequency measurements is limited when sediment properties are changing.
Using multi-frequency measurements, mea...

Key messages The pandemic increased poverty in Africa by less than expected, approximately 1.5-1.7 percentage points in 2020. Countries affected by Fragility, Conflict, and Violence (FCV) experienced the greatest increases in poverty. An emerging literature establishes that social protection programs in Africa during the pandemic had positive...
Forsa, which means “Opportunity” in Arabic, is a new economic inclusion program of the government of the Arab Republic of Egypt. Implemented by the Ministry of Social Solidarity, the program aims to graduate beneficiaries of the national cash transfer program, the Takaful & Karama Program (TKP), to economic self-reliance by enabling them to engage ...
The Forsa program, launched in 2021 by the Egyptian Ministry of Social Solidarity has been designed as a graduation program targeted to current beneficiaries of the Takaful cash transfer program. To understand how well Forsa supports household income generation and to better understand the beneficiary household characteristics which may relate to p...
