International Interdisciplinary Conference on

Land Use and Water Quality

Agriculture and the Environment

Maastricht, the Netherlands, 12-15 September 2022


LuWQ2022 is an international and interdisciplinary 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.

Objectives of the conference are:

  • to provide a forum for exchange of scientific knowledge, research to better understand ’systems function’, modelling and uncertainty;
  • to discuss the entire policy cycle for water quality improvement;
  • 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.

Conference is jointly convened by:

LuWQ2022 is the follow-up to the successful LuWQ conferences, 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 the LuWQ2013 conference held in The Hague, the Netherlands, in June 2013.

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.

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.

No need to explain why we had to undergo all these troubles. However, be assured that we never complained…

We indeed look forward to meet with you in Maastricht during 12-15 September 2022!
