The role of science in agricultural climate mitigation

In this paper, FCRN members Pip Brock and Daniel Tan examine how Life Cycle Assessment (LCA) is used as a tool for informing resource-use decisions. They contend that two different schools of thought - natural resource management and planning theory - would benefit by learning from each other.

Natural resource management generally takes a so-called rational-comprehensive approach to decision-making, whereby people attempt to think of every possible course of action, tally up the costs and benefits of each approach, and select the optimum approach. Planning theory, in contrast, often focuses on making step-by-step changes that meet the interests of people affected by each action, rather than aiming for a predetermined optimum state.

Two problems faced by LCA practitioners include: 

  1. Deciding how to allocate impacts between two or more co-products of a single process, and 
  2. accounting for knock-on effects that might occur in markets when production levels of one item change. 

Brock and Tan argue that planning theory can be applied to LCA. Regarding allocation of impacts between co-products, a planner (practitioner of planning theory) would rather include affected stakeholders in discussions about how scenarios might play out when different allocation methods are used, rather than trying to find the best or most precise allocation methods. 

Regarding accounting for market changes, planners might be concerned that LCAs could be seen as more authoritative than they really are, because predicting market substitutions and shifts is highly uncertain. Planners would rather use a series of different LCA scenarios as an input for decision-making, rather than seeking one complete LCA and basing decisions on that one LCA.

 

Abstract

Background

Natural resource management theory has been informed by disciplines such as ecology, agricultural science, economics and engineering; but much less so by the literature of planning and public administration. This paper demonstrates that applying an incremental view to what is traditionally seen as a rational-comprehensive discipline provides insights into resource management theory and practice, including adaptive management.

Results

We show how current theory and practice in natural resource management are not aligned to the degree that is routinely presumed. In particular, the prevailing focus on optimality creates conflicts, especially during democratic decision-making, whereas adopting a participatory-incremental hybrid approach should provide a superior solution, which is discussed here in the context of Life Cycle Assessment by resource managers.

Conclusion

Resource management tends to be both incremental and participatory; and whilst decisions are strongly informed by science, on reflection, the process of formulating decisions is rarely rational-comprehensive. We suggest greater retrospective analysis of resource management decisions at a theoretical level. This may result in adoption of a theoretical framework which better supports practice, a reduction in tensions between those trained in the arts and sciences; and more ‘freedom’ in practice, through a softening of the focus on optimality.
