He made no attempt to broaden his government or to mitigate its program of putting money in the pockets of the rich, rolling back environmental protections, favoring energy extraction over conservation, and the rest.
A more serious concern, says Williams, former chief of CSIRO Land and Water, is the need to persuade Marshall to shift his focus from water extraction to conservation.
The social and economic purposes for which land is managed (e.g., grazing, timber extraction, and conservation).
Lower wealth households were more likely to admit extraction, supporting the conservation narrative that poverty constrains conservation.
Finally, swidden fallows could potentially be managed for enhanced Brazil nut densities, which may provide an opportunity for greater income for extractive families while contributing to the sustainability of Brazil nut extraction and forest conservation in the long term.
It is unclear whether high risk land zones are identified as such because they are close to access routes, or are placed near access routes for the intention of enabling resource extraction and non-conservation uses.
What makes these negotiations difficult is the tension between conservation and extraction.
Our approach of selecting fishing areas instead of reserves could help redirect debate about the relative values that society places on conservation and extraction, in a framework that could gain much by losing little.
As explained in the introduction, for reaction models these invariants are used for flux analysis, variable simplification through conservation law extraction, module decomposition, etc.
Conservation law extraction is actually already provided by a few tools, but then using numerical methods, based on the quantitative view of the model, and not integer arithmetic (as in direct P-invariant analysis).
