For Maxergy version 3 a tool is not directly needed, that is, its an easy calculation of adding up all impacts in terms of ha-year based on data provided here and possibly contributed by other researchers.

Of course its still required to not only look to the actual direct impact but also include the secondary and tertiary impacts. ( for agriculture think of fertilizer, pesticides, transport, storage etc. see example calculation for potato crops here: [x] )

First there is a table with the space time potentials of many resources, the INPUT side. Or ‘The Offer’, and links to original documents.

The second table is a listing of space time requirements for a first set of activities. ( The OUTPUT, or the demand )

the sources, detailed explanations, or analyses are referred to in the accompanying documents.

INPUT data:

This is the INPUT data, the known yields per hectare so far , or the maximum ‘forming capacity’ per hectare, as far as available currently. See for some explanations under method. Links to the references and sources are given in this document:

one of the documents referred to, is this one, which has a collection of short analyses of several different resources:

You can also download the excell file, but its under development.

OUTPUT :

These are data for Land Embodied by specific activities. Its a minimum, not all secondary and or tertiary impacts are counted for. Its under development, and sources for data mainly described in the Book: ‘Space time economy’ , but they will be separately published as blogs later. Some references are collected in this file here:
