Short introduction to ALMaSS

Alle under sider til ALMaSS findes i øjeblikket kun på engelsk

ALMaSS, The Animal, Landscape and Man Simulation System is a landscape scale simulation system for investigating the effect of changes in landscape structure and management on the population size and distribution of animals in the Danish landscape.

ALMaSS is since 2010 an open-source open-science project hosted on GitLab. The ALMaSS project page provides news, access to reprints and codes, and forums to discuss the ALMaSS project. Anyone interested in using or contributing to ALMaSS is encouraged to join GitLab and the ALMaSS project. 

ALMaSS Overview

ALMaSS is an agent-based model system, which means that the animals are modelled as individuals (agents) which will move around inside a virtual landscape to breed and die much in the same way as the real animals do in their natural environment.

Apart from the detail often used in ALMaSS models, what sets this system apart from others is that from its conception it has utilized dynamic landscapes rather than static maps. A very substantial part of the system is therefore the modelling of environment that the animal models are placed into. See landscape for further details.

 Development of ALMaSS was initiated in 1998 using a strategic research project under the ”Jordbrugeren som landskabsforvalter” programme. Development has continued unabated since that point until the code base for ALMaSS is some 70 000 lines of C++ describing the behaviour and ecology of a range of species as well as their virtual world.

The primary goals of ALMaSS at its conception were:

  • To create an impact assessment and management tool to evaluate the effect of changing landscape structure and management on animal populations in the Danish landscape.
  • To integrate current knowledge regarding key animal species into a single model and use this to guide future scientific endeavour.

Subsequently ALMaSS has been applied to a wide range of projects including assessing the impact proposed development of land, analysing impacts of proposed and potential government policy change, for risk assessment of agrochemicals, population genetics and for theoretical population ecology.

Documentation of the ALMaSS code is an ongoing project and the latest documentation version can be found here: ALMaSS ODdox 

This documentation is in ODdox format, a format we have devised to describe large agent-based models in an easily navigable form.

ALMaSS intl. meeting & workshop

October 10, 2019

We are excited to announce that we are hosting the first international ALMaSS meeting 11-12 November 2019 in Denmark. The purpose of this meeting is for the international ALMaSS team to come together and talk about the work we are doing related to development and use of ALMaSS models.­­

The meeting will be followed by a workshop 13-22nd November where the local ALMaSS team will be available to help with technical issues, model development, tool set-up etc. as needed.

We look forward to hosting the event, and we hope it will be a successful experience, which will become a reoccurring event moving between the ALMaSS collaborators. 


H2020 EcoStack project video

Here is a small video introduction to the new H2020 project, EcoStack, about stacking ecosystem services to promote sustainable crop production. ALMaSS contributes to this project by simulating EcoStack scenarios across the EU.
