How to get started

You can:

  • try out the package using the provided example data in the Data-Tab taken from Gosling et al. (2020).
    It is a study that took place in a forest frontier region in Eastern Panama and used data from interviews with local farmers. The farmers ranked the performance of different conventional land-cover types and two agroforestry land-cover types against various socio-economic and ecological indicators. The data table contains the necessary expectations and uncertainties.

  • upload your own dataset with which strictly follows the format specifications of the example data:
    • Indicators for different land cover types
    • with their average expectations and uncertainties
    • and a further column with the direction for each indicator to indicate whether more or less of the indicator is desirable

  • go to Tab Data to upload the example data or your own data
  • go to Tab Model to perform the optimization and evaluate the results.

Package Info

This is a graphical shiny application for the package optimLanduse to get a quick idea of the functionalities of the package. optimLanduse (version 1.1.0) has been released on CRAN and can be accessed via the project page.

Short summary

  • How to simultaneously combat biodiversity loss and maintain ecosystem functioning while increasing human welfare remains an open question. Multiobjective optimization approaches have proven helpful in revealing the trade-offs between multiple functions and goals provided by land-cover configurations. The R package optimLanduse provides tools for easy and systematic applications of the robust multiobjective land-cover composition optimization approach of Knoke et al. (2016).

  • The package includes tools to determine the land-cover composition that best balances the multiple functions a landscape can provide, and tools for understanding and visualizing how these compromises are reasoned. A tutorial on the basis of a published data set guides users through the application and highlights possible use-cases.

  • Illustrating the consequences of alternative ecosystem functions on the theoretically optimal landscape composition provides easily interpretable information for landscape modeling and decision making.

  • The package opens the approach of Knoke et al. (2016) to the community of landscape and planners and provides opportunities for straightforward systematic or batch applications.
