LuWQ2022 - 5th International Interdisciplinary Conference on ’’LAND USE AND WATER QUALITY: Agriculture and the Environment’’ (Maastricht, The Netherlands, 12-15/09/2022)

Dear colleagues,


PLEASE MARK YOUR CALENDAR – LuWQ2022, 12-15 September 2022, Maastricht, The Netherlands – and plan to submit an abstract to the conference.


A conference on the cutting edge of science, management and policy to minimise effects of agriculture and land use changes on the quality of groundwater and surface waters.



5th International Interdisciplinary Conference on


Agriculture and the Environment

Maastricht, the Netherlands, 12-15 September 2022.


Activation of webpage for abstract submission on Monday 25 October 2021.

Deadline of abstracts submission is Monday 7 February 2022.


More information is on website


Jointly convened by

  • RIVM National Institute for Public Health and the Environment, Centre for Environmental

Quality, the Netherlands

  • DCE - Danish Centre for Environment and Energy, Aarhus University, Denmark
  • Department of Bioscience, Aarhus University, Denmark
  • Geological Survey of Denmark and Greenland (GEUS), Denmark
  • Umweltbundesamt (UBA), Federal Environment Agency, Germany



The conference aims to discuss the entire ’policy cycle’ to enable enhancing the quality of the water environment, which includes problem recognition, formulation of technical options, policy formulation, interaction between policy makers and stakeholders (i.e. pressure groups), policy implementation, monitoring and research. The conference also aims to facilitate networking opportunities between scientists of different discipline backgrounds i.e. economic, social and natural sciences, as well as between scientists, water managers and policy makers. In short, the objectives are:

  • to provide a forum for exchange of scientific knowledge, research to better understand ’systems function’, modelling and uncertainty;
  • discuss the entire policy cycle for water quality improvement; and
  • to intensify contacts (a) between soil/water related scientists, agro-related scientists, social scientists, ecological scientists and economists, and (b) between scientists, water managers and policy makers.


LuWQ2022 is the follow-up to the previous successful LuWQ conferences, namely LuWQ2019 ( held in Aarhus, Denmark, in June 2019, LuWQ2017 held in The Hague, the Netherlands, in June 2017, LuWQ2015 held in Vienna, Austria, in September 2015 and LuWQ2013 held in The Hague, the Netherlands, in June 2013.


History of development of LuWQ2022 conference…

•         We started with LuWQ2021 conference, initially planned for 17-20 May 2021;

•         then we decided to postpone the conference by four months until 13-16 September 2021;

•         then – to avoid very high hotel prices in Maastricht due to an unexpectedly scheduled huge exhibition in MECC during “our” dates 13-16 September – we postponed LuWQ2021 by two weeks until 27-30 September 2021;

•         and finally, was postponed LuWQ2021 to 12-15 September 2022 and renamed it to LuWQ2022.


We have two versions of the flyer available, A3-page and A4-page. You can download the conference flyers from


To give you a feeling for the essence of Land Use and Water Quality (LuWQ) conferences… The key strength of the conference is twofold. On the one side, LuWQ has a well-defined narrow focus on ‘agriculture and water quality’. On the other side, the conference is broadly oriented with regard to the various professional disciplines related to the conference topics. Based on the experience from previous Land Use and Water Quality conferences, it is just the diversity in professional background of participants which results in a multi-faceted conference programme. Consequently, LUWQ offers sessions on a broad variety of topics, all of them however dedicated exclusively to agriculture and water quality. In this sense, the conference topics range – to illustrate by a few randomly chosen examples – from scientific research on denitrification and travel time, …, challenges in monitoring and modelling at different scale (parcels, field, region), …, practice-oriented and technical measures to limit leaching of nutrients and agrochemicals, …, development of management options to mitigate effects on water quality in drinking-water protection areas, including cooperation between local governments, water supply companies and farmers, …, to policy development, and lessons to be learned from policy implementation, e.g. comparison of farmers’ behaviour between top-down and bottom-up implementation of agri-environmental measures.


Conference target groups and keywords


Conference target groups (professionals, fields of expertise, audience) are scientists, managers and policy makers involved in the policy cycle for water quality improvement.


The conference deals with themes and topics characterised by the following keywords:

-      Keywords for fields of expertise and scientific disciplines: agronomy, agro-economics, agro-sociology, water management, water policy, action plan, river basin management plan, hydrology, soil science, drinking water supply, data analyses (including data sharing)

-      Keywords for system description: aquatic ecosystems, terrestrial ecosystems, unsaturated zone, groundwater, surface waters, monitoring, modelling, chemical water quality, biological water quality, nitrate vulnerable zones, river basins, catchments

-      Keywords for best management practices: buffer zones, sedimentation ponds, constructed wetlands, incorporation of fertilisers, catch crops, erosion control, cost effectiveness

-      Keywords for policies and implementation: voluntary measures, laws and regulations, participatory governance, top down versus bottom up, building relationships, gaining trust, raising awareness, evidence based approach

-      Keywords for substances: nutrients, nitrate, phosphorus, pesticides and other organic agrochemicals, heavy metals




Contributions are solicited according to the following themes, themes A through I:

A.. Increasing our understanding of ‘systems function’: research, tools and methodologies to increase understanding and improving modelling of the hydro(geo)logical, geochemical and biochemical processes

B.. Water quality monitoring: improving the effectiveness and increasing the added value of monitoring – use of new sensor techniques, remote sensing, improved (meta)data management, analysis and interpretation, modelling and generalisation of observations, and assessment of status and trends

C.. Impact of weather variability and climate change on water quality: assessment of impact on land use, groundwater and surface water quality

D.. Assessment of national or regional policy: effectiveness of programmes of measures on water quality on a regional and national scale

E.. Improving water quality by farm management practices: research (monitoring and modelling) at plot, field and catchment scales to quantify the effects of farming practices and changes in land use

F.. Improving water quality by establishing eco-technological mitigation measures: development, testing, implementation and operation at plot, field and catchment scales to quantify the effects of structural measures

G.. Managing protected areas for water supply and nature conservation: risk assessment techniques, monitoring and modelling of water quality and quantity for the protection of (a) water resources for drinking water supply, and (b) groundwater dependent terrestrial ecosystems

H.. Decision-making on Programmes of Measures: the role of stakeholder input and science in policy decision-making

I.. Implementation of Programmes of Measures: social and economic incentives and regulatory mandates that drive implementation (carrots and sticks), catchment officers, etc.

We would appreciate if you would announce the LuWQ2022 conference by direct emails to your own contacts (colleagues across the country etc.), professional communities in your country, and your networks. Announce, for example, at: 

  • University institutes dealing with agriculture and water quality;
  • Relevant research institutions / organisations;
  • ministries and state authorities (policy makers) involved in agricultural management and water quality improvement (on national, regional, provincial level etc.);
  • stakeholder groups like water supply companies and chambers of agriculture etc.


Thank you for your assistance!


With kind regards,
