Agent-Based Models

On code sharing and model documentation of published Individual and agent-based models

Thursday, June 4, 2020

Being able to replicate research results is the hallmark of science. Replication of research findings using computational models should, in principle, be possible. In this manuscript, we assess code sharing and model documentation practices of 7,500 publications about individualbased and agent-based models. The code availability increased over the years, up to 18% in 2018.

Food Security in the Face of Climate Change: Adaptive Capacity of Small-Scale Social-Ecological Systems To Environmental Variability

Wednesday, October 28, 2015

Improving the adaptive capacity of small-scale irrigation systems to the impacts of climate change is crucial for food security in Asia. This study analyzes the capacity of small-scale irrigation systems dependent on the Asian monsoon to adapt to variability in river discharge caused by climate change. Our study is motivated by the Pumpa irrigation system, a small-scale irrigation system located in Nepal that is a model for this type of system.

Using Agent-Based Models to Compare Behavioral Theories on Experimental Data: Application for Irrigation Games

Friday, February 20, 2015

Behavioral experiments have demonstrated that people do cooperate in commons dilemmas. The traditional theory of selfish rational behavior is clearly falsified. However, we lack agreement on alternative formal models to explain the actions seen in the lab and beyond. In this paper, we will use agent-based models to compare alternative behavioral theories on a series of experimental data of irrigation games.

Bene fits of Grouping and Cooperative Hunting Among Ache Hunter-Gatherers: Insights from an Agent-Based Foraging Model

Wednesday, September 18, 2013

We develop an agent-based model of foraging behavior based on ecological parameters of the environment and prey characteristics measured in the Mbaracayu Reserve Paraguay. We then compare predicted foraging behavior from our model to the ethnographically observed behavior of Ache hunter-gatherers who inhabit the region and show a close match for daily harvest rates, time allocation, and species composition of prey.

What to Monitor and at which Scale: Fragmented Landscapes and Insights on Large-Scale Conservation Management

Monday, January 7, 2013

In recent years there has been a shift in biodiversity conservation efforts from the confines of enclosed protected areas to a more expansive view of interlinked habitat patches across multiple land tenure types and land uses. However, much work remains on how conservation managers can intervene in such a system to achieve the sustainability of basic conservation goals.

Mobility, Resource Harvesting and Robustness of Social-Ecological Systems

Wednesday, October 3, 2012

Globalization is an important feature affecting the robustness of small-scale social-ecological systems (SESs). Understanding the way globalization affects those systems is crucial for adaptation. In this paper we focus on analyzing how the increased displacement of resource users as a consequence of globalization affects the robustness of SESs. We developed a stylized agent-based model representing a dynamic population of agents moving and harvesting a renewable resource.
