This conclusion presents some closing thoughts on the key concepts discussed in the preceding chapters of this book. The book explores instances where economic valuation systems are being newly proposed, assembled and/or deployed in the fields of development, environment and conservation. It examines how white commercial farmers were able to subvert legislation drafted to promote redistribution of water rights and instead use a category of existing legal use to maintain their privilege. The book argues that attending to the limits of economic valuations is worthwhile, as these limits may be leveraged in struggles against the progressive economisation of worth in the fields of development, environment and conservation. The first and most obvious source of limits to economic valuation is the difficulty in achieving commensurability between valued entities. The limits of economic valuation often seem to only encourage further iterations of economic values and economising practices.
