Different types of vegetation in riverine landscapes, ranging from grass on dikes to shrubs and trees in floodplains.

Project output

A quantitative and qualitative analysis of residual biomass use from vegetation management in riverine areas.

Challenge

The land surrounding rivers is characterized by arable soils and high vegetation growth. Where floodplains are not occupied by agricultural production, vegetation must often be removed to ensure sufficient discharge capacities during high water levels. Water management organizations are interested in using biomass from riverine vegetation as ecosystem service. Riverine residual biomass can serve as resource for the bioeconomy and can be considered an Ecosystem Service, contributing to a more self-supporting river system. It is yet unclear which biomass applications are the most sustainable and how sustainable use of residual biomass can be achieved.

Key goals: Collaborative Governance Integrated management

Overview of the greenhouse gas emissions of different residual biomass applications and the processing locations in the Netherlands.

Innovative components

In this project, we compare the carbon footprint of different applications of riverine biomass and analyze how biomass use is currently organized by Dutch water management organizations. We combine quantitative and qualitative methods and applied a transdisciplinary approach, considering both stakeholder knowledge and experiences. We provide data on current practice and organisational structures which are valuable to practitioners in the Netherlands and internationally. Our project also provides an extensive comparison of the greenhouse gas emissions of different residual biomass applications, showing that some uses result in emission benefits and others in burdens (see Figure).

For whom and where?

Vegetation management departments of water management organisations in the Netherlands and internationally.

Data-collection methods: Interviews Life Cycle Assessment

Temporal scale: Project duration

Application development & findings

We found that changing the use of residual biomass to provide resources to a bioeconomy is not automatically sustainable. We analyzed how vegetation management and the use of biomass is currently organized in water management organizations and found that there is a trend to consider the use of residual biomass as an ecosystem service, contributing to the bioeconomy. But formal comparison tools to be applied in tendering procedures are lacking, resulting in trial and error approaches and uncertainty.

Vegetation management practices should be adapted to make optimal use of residual biomass as an ecosystem service. Changing tendering procedures to include sustainability evaluation of biomass harvest and biomass use can stimulate creative solutions to collect biomass, instead of leaving it behind, and finding feasible, societally relevant applications.

Status for day-to-day practice

There are currently no formal, objective evaluation methods to compare the sustainability merits of different residual biomass applications. The insights and data from this project should be used to develop tools for vegetation managers to compare different applications during tendering procedures in the future.

Key locations where the study took place.

Key locations: IJssel River (NL) Nederrijn-Lek River (NL) Rhine River (NL) Waal River (NL)

Spatial scale: Delta scale

Next steps

The insights and data from this project should be used to develop tools for vegetation managers to compare different applications during tendering procedures in the future.
