A Snapshot of the World’s Water Quality: Towards a Global Assessment – 2016

A Snapshot of the World’s Water Quality: Towards a Global Assessment

The World Water Quality Assessment pre-study has developed a data and model-driven methodology to assess the quality of surface waters, measure progress and identify pathways towards sustainable solutions. The final report summarizes the most important results including types, intensity and sources of water pollution, potential impacts on human health and food security as well water quality data and information gaps. With the contribution of Philipp Saile from the ICWRGC, chapter 2 provides an overview of the current observational knowledge and GEMS/Water’s role as the primary source of global water quality data. Further developing and strengthening GEMS/Water and its associated online database GEMStat will support a reliable global assessment of water quality in the future.

Training Guidelines on Integrated Flood and Drought Management – 2015

Training Guidelines on Integrated Flood and Drought Management

Biljana Radojevic, November 2015 Floods and droughts are the greatest water-related natural disasters known to mankind – their human, material and ecological cost can be devastating to sustainable development. Countries have developed integrated flood and drought management plans and policies.

Training Guidelines on Integrated Flood and Drought Management Biljana Radojevic, November 2015

Training Guidelines on Integrated Flood and Drought Management
Biljana Radojevic, November 2015

Flood and drought risks are defined based on the vulnerability of the affected areas, therefore preparedness and anticipation are the key actions to limit hazard risk. Preparedness plans are developed on the basis of regional climate, economic, and social conditions. These guidelines on integrated flood and drought management aim at providing all necessary elements needed for a successful flood and drought management at the country level, particularly for least developed countries. Best practice of different countries is an essential component of these guidelines.

Workshop Report - Exploring new data for monitoring of water SDGs – 2015

On 30 November and 1 December 2015 the workshop “Exploring new data for SMART monitoring of water SDG targets” took place in the House of the Regional Government in Maastricht, The Netherlands. The workshop was organized by the Netherlands National IHP-HWRP Committee Secretariat and jointly convened by the National IHP-HWRP Committees of The Netherlands, Germany and Belgium.

Workshop Report – Exploring new Data, for SMART monitoring of water SDG targets. 30 November – 1 December 2015, Maastricht

The workshop brought together more than 40 scientists, policy-makers and practitioners from the three countries, who analyzed the present state of monitoring in their countries; looked into the water-related targets of the Sustainable Development Goals (SDGs) and their indicators; presented innovative data collection and monitoring techniques; and identified gaps between what is currently being monitored and what needs to be monitored to fulfill the monitoring responsibilities of the water SDGs .

Estimation of the predictive uncertainty of hydrological model simulations and forecasts – 2015

Estimation of the predictive uncertainty of hydrological model simulations and forecasts

This article presents a hitherto relatively rare method to estimate predictive uncertainty of hydrological model simulations and forecasts. The probability distribution of uncertainty is ascertained by means of a statistical analysis of the model performance in the past.

Updating initial states of the HBV hydrological model by means of an Ensemble Kalman Filter to improve discharge forecasting – 2014

Updating initial states of the HBV hydrological model by means of an Ensemble Kalman Filter to improve discharge forecasting – 2014

The report illustrates the potential of data assimilation to improve discharge forecasting by means of the HBV hydrological model in two tributaries of the Rhine. In the process, both observed discharge values are assimilated into the applied hydrological model as well as spatially distributed data of the snow water equivalent and soil moisture. The data assimilation process provides so-called updated initial conditions for discharge forecasts and evaluates the quality of the forecasts by means of objective and aggregated criteria.

Historical carbon dioxide emissions caused by land-use changes are possibly larger than assumed (Nat. Geosci.) – 2017

Historical carbon dioxide emissions caused by land-use changes are possibly larger than assumed (Nat. Geosci.)

The terrestrial biosphere absorbs about 20% of fossil-fuel CO2 emissions. However, the land sink is composed of two largely counteracting fluxes that are poorly quantified: fluxes from land-use change and CO2 uptake by terrestrial ecosystems. Dynamic global vegetation model simulations suggest that CO2 emissions from land-use change have been substantially underestimated and that terrestrial ecosystems might have greater potential to sequester carbon in the future.

Resilience in the global food system (ERL) – 2017

Resilience in the global food system (ERL)

This study results from an international cooperation mainly funded by the National Socio-Environmental Synthesis Center (SESYNC) of the United States and quantifies a national-scale resilience indicator for the years 1992-2011. This indicator is based on three dimensions of resilience: biophysical capacity to intensify or extensify food production, including water resources, socio-economic access to food in terms of income of the poorest quintile relative to food prices, and the magnitude and diversity of current domestic food production.

Green and blue water demand from large-scale land acquisitions in Africa (PNAS) – 2016

In the last decade, more than 22 million ha of land have been contracted to large-scale land acquisitions in Africa, leading to increased pressures, competition, and conflicts over freshwater resources. We use a dynamic global vegetation model to simulate water demand and crop yields for seven irrigation scenarios. We identified hotspots areas at risk for transgressing regional constraints for freshwater use as a result of overconsumption of irrigation water, where socioenvironmental systems might face increased conflicts and tensions over water resources.

Reserves and trade jointly determine exposure to food supply shocks (ERL) – 2016

Does the increased reliance on trade benefits or hinders food security? This paper introduces a model that simulates the short-term response to a food supply shock in the global trade network. The study also identifies countries where trade dependency may accentuate the risk of food shortages from foreign production shocks.

Probabilistic flow and water-level forecasts – communication strategies and potential uses for inland navigation (HyWa) – 2014

Probabilistic flow and water-level forecasts – communication strategies and potential uses for inland navigation

Hydrology and Water Resources Management (Hydrologie und Wasserbewirtschaftung, 58. Jahrgang, Heft 2, April 2014)

A central aspect many forecast centres are concerned with, is finding an adequate way of communicating the calculated uncertainties. This might be one of the main reasons for the prevailing reluctance to publish probabilistic forecasts. Only if we succeed in transforming the undisputed theoretical advantage of probabilistic forecasts into practical use, establishing probabilistical forecasts will go beyond being a purely academic exercise.

Ascertainment of probabilistic runoff forecasts considering censored data (HyWa) – 2014

When forecasting water levels and river flow, ensemble weather forecasts are frequently used as meteorological input to hydrologic process models. In hydrologic forecasting systems, data below or above certain threshold values are subject to increased uncertainty. In this study, two sub-catchments of the River Rhine are considered. The forecasting systems associated with these two catchments use runoff data that are censored below a predefined threshold value. On the basis of Ensemble Model Output Statistics (EMOS), a censored EMOS method is developed that is able to cope with censored data. Censored EMOS will then be verified over the entire forecast time horizon of 1 to 114 hours using several different statistical measures.
