Singirankabo, U.A. (author), Ertsen, M.W. (author), van de Giesen, N.C. (author)On the basis of a data set from four research sites over the course of three agricultural years (2006/2007, 2012/2013, 2016/2017), this article empirically assesses the relations between land tenure security and smallholder farms’ crop production in Rwanda. We show that the general assumption that secure land tenure improves farm level...journal article 2022

Vermunt, P.C. (author), Steele-Dunne, S.C. (author), Khabbazan, S. (author), Judge, Jasmeet (author), van de Giesen, N.C. (author)Microwave observations are sensitive to vegetation water content (VWC). Consequently, the increasing temporal and spatial resolution of spaceborne microwave observations creates a unique opportunity to study vegetation water dynamics and its role in the diurnal water cycle. However, we currently have a limited understanding of sub-daily...journal article 2022

van Amelrooij, Edward (author), van de Giesen, N.C. (author), Plomp, J. (author), Thijs, M.A. (author), Fico, Tomáš (author)A newly developed Boron-based Large-scale Observation of Soil Moisture (or BLOSM) system is currently being tested and implemented. The stationary system provides a cost-effective way to measure fast and thermalized neutrons by using low-cost, non–hazardous and accessible materials and equipment. BLOSM operates by measuring cosmic-ray induced...journal article 2022

Kaandorp, C. (author), Miedema, T. (author), Verhagen, J.D. (author), van de Giesen, N.C. (author), Abraham, E. (author)Infrastructure for heat provision in the built environment needs to change remarkably to support lowering carbon emissions and achieving climate mitigation targets before 2050. We propose a computational approach for finding a mix of heat options per neighbourhood that minimises cumulative carbon emissions between 2030 and 2050, referred to as...journal article 2022

van der Heijden, T.J.T. (author), Palensky, P. (author), van de Giesen, N.C. (author), Abraham, E. (author)In this manuscript we propose a methodology to generate electricity price scenarios from probabilistic forecasts. Using a Combined Quantile Regression Deep Neural Network, we forecast hourly marginal price distribution quantiles for the DAM on which we fit parametric distributions. A Non-parametric Bayesian Network (BN) is applied to sample from...conference paper 2022

(author), Albers, Thomas (author), Alidoost, Fakhereh (author), Andela, Bouwe (author)Hutton et al. (2016) argued that computational hydrology can only be a proper science if the hydrological community makes sure that hydrological model studies are executed and presented in a reproducible manner. Hut, Drost and van de Giesen replied that to achieve this hydrologists should not “re-invent the water wheel” but rather use existing...journal article 2022

Singirankabo, U.A. (author), van de Giesen, N.C. (author)The year 2007 marked the beginning of a journey to secure food in Rwanda. The country introduced the Crop Intensification Program (CIP), which promotes the farmland use consolidation (LUC). This study assesses the effect of farmland use changes on the agriculture production. We collected data at four research sites and considered three...journal article 2022

Kaandorp, C. (author), van de Giesen, N.C. (author), Abraham, E. (author)Sustainable energy systems can only be achieved when reducing both carbon emissions and water use for energy generation. Water-energy nexus studies are therefore crucial for supporting environmental policy oriented towards the mobilisation of resources in an optimally integrated way. Decarbonizing heating infrastructures is an important part of...abstract 2021

de Villiers, D.J. (author), Schleiss, M.A. (author), ten Veldhuis, Marie-claire (author), Hut, R.W. (author), van de Giesen, N.C. (author)A new type of rainfall sensor (the intervalometer), which counts the arrival of raindrops at a piezo electric element, is implemented during the Tanzanian monsoon season alongside tipping bucket rain gauges and an impact disdrometer. The aim is to test the validity of the Poisson hypothesis underlying the estimation of rainfall rates using an...journal article 2021

(author), van de Giesen, N.C. (author)In 2009, the International Soil Moisture Network (ISMN) was initiated as a community effort, funded by the European Space Agency, to serve as a centralised data hosting facility for globally available in situ soil moisture measurements . The ISMN brings together in situ soil moisture measurements collected and freely shared by a multitude of...review 2021

le Coz, C.M.L. (author), Heemink, A.W. (author), Verlaan, M. (author), van de Giesen, N.C. (author)Many satellite-based estimates use gauge information for bias correction. In general, bias-correction methods are focused on the intensity error and do not explicitly correct possible position or timing errors. However, position and timing errors in rainfall estimates can also lead to errors in the rainfall occurrence or the intensity. This is...journal article 2021

Kaandorp, C. (author), van de Giesen, N.C. (author), Abraham, E. (author)Sustainable energy systems can only be achieved when reducing both carbon emissions and water use for energy generation. Although the water use for electricity generation has been well studied, integrated assessments of the water use by low-carbon heat systems are lacking. In this paper we present an analysis of the water use of scenarios for...journal article 2021

(author)Plastics originating from land are mainly transported to the oceans by rivers. The total plastic transport from land to seas remains uncertain because of difficulties in measuring and the lack of standard observation techniques. A large focus in observations is on plastics floating on the water surface. However, an increasing number of...journal article 2021

Tariq, Muhammad Atiq Ur Rehman (author), Farooq, Rashid (author), van de Giesen, N.C. (author)Modern-day flood management has evolved into a variety of flood management alternatives. The selection of appropriate flood measures is crucial under a variety of flood management practices, approaches, and assessment criteria.

Tariq, Muhammad Atiq Ur Rehman (author), Farooq, Rashid (author), van de Giesen, N.C. (author)All over the world, probability-based flood protection designs are the ones most commonly used. Different return-period design floods are standard criteria for designing structural measures. Recently, risk-based flood management has received a significant appraisal, but the fixed return period is still the de facto standard for flood...review 2020

(author), Coyte, Rachel (author), van de Giesen, N.C. (author)Irrigated agriculture contributes 40% of total global food production. In the US High Plains, which produces more than 50 million tons per year of grain, as much as 90% of irrigation originates from groundwater resources, including the Ogallala aquifer. In parts of the High Plains, groundwater resources are being depleted so rapidly that they...journal article 2020

Wang, Z. (author), Hut, R.W. (author), van de Giesen, N.C. (author)Particle filters are non-Gaussian filters, which means that the assumption that the error distribution of the ensemble should be Gaussian is unnecessary. Like the ensemble Kalman filter, particle filters are based on the Monte Carlo approximation to represent the distribution of model states. It requires a substantial number of particles to...journal article 2020

(author)Plastic debris in water systems is a major challenge for our ecosystem, because it is extremely persistent in the environment. Apart from the importance of reducing the amount of plastic entering the ocean, clearing the rivers from debris is important for societal concerns, such as flood risks. Plastic waste accumulation at trash racks leads...journal article 2020
