Re: Back to the Land Economy

Márta 9, 2009

Considering “Land Economy,” we can also understand three dimensions of value – a “LAND Cube” – that Land represents:

1. “Land And Natural-resource Distribution” (utility in efficient allocation of raw material & natural capital);
2. “Location ANd Demographics” (Location values, Access to markets & services, Network effects & infrastructure, Demographic gravity & energy);
3. “Limiting Assets of Natural Development” (Land and land-like phenomena, fundamental means of production that are the limiting factors of all other economic processes).

We tend to compartmentalise all of these values as seperate, but all sets of these elements overlap the ownership and use of any parcel of physical land (although no. 3 also includes money, credit & cultural capital).

Mr. Berry isn’t just talking about efficient allocation of natural resources of course, but about the social capital and demographic networks of vibrant communities; the unofficial “added value” of social infrastructure that runs with the land like an easement on a title deed.

Space, Time, Energy, Matter, Information – 2

Samhain 17, 2008

L.A.N.D.2:

Space, the final frontier... BP = d / (1 + ( √ (m²1 / m²2))

Space, the final frontier... BP = d / (1 + ( √ (m²1 / m²2))

“… a new geography is being created within which physical distance is less important than electronic connectedness. ” (Seeking source 081117)

Recapping, in paraphrase, STEMI Compression:

STEMI compression in design evolution, as applied to Resilient Communities –
– Space: less volume/area used; “localization… reduction of space needed to support human activity”;
– Time: faster; Just-In-Time production;
– Energy: less energy, higher efficiency; Just-In-Place production reduces transport;
– Mass: less waste; made to order versus mass production;
– Information: “higher efficiency, less management overhead… radical simplification”;

Hypothesis set A:

  1. Limiting Assets – Natural, National, Network Development (Locational ANd Demographic) or L.A.N.D.^2 values, exist;
  2. these values are the result of positive externalities which are due to:
    • intentional investments of site-specific material and social infrastructure;
    • natural opportunities and exogenous natural capital;
    • exposure to social opportunities and demographic energy, access to market, social capital;
  3. These contain both rival and non-rival public goods;
  4. Overuse of non-rival goods can result in them becoming rival;
  5. The rationalisation of provision, or rationing of rival goods, is necessary;
  6. State-allocation is hampered by the problem of cost calculation absent market signals;
  7. Allocation through state-led privatisation of rival goods leads to negative externalities – socialisation of cost, privatisation of profit;

Hypotheses set B:

  1. Technology and design – investment of knowledge – reduce effective spatial and time distance;
  2. Technology and design reduce effective material and energy use;
  3. Both the reductions of effective space-time and matter-energy can be thought of as as reductions of resistance to human action and desire;
  4. The control of such technology and design is equivalent to control of other aspects of LAND2 (hence Infrastructure and Network);
  5. Bottlenecks in such control – whether intentional or not – create an institutional toll-bridge which the rest of society must pay;

Some previous thinkers on demographic energy, locational value, and technology…

Fuller uses as an example of this the Telstar satellite which. while weighing only one-tenth of a ton, out-performs 75,000 tons of transatlantic cable…
… substitution not only in materials but in functions… may vastly alter our lives, effecting how we otherwise spend our energy and time. For example, communications as a substitution for transportation can effect such savings to a great extent…
A society that exercises this option of using communication in place of transportation in many of its activities … can conserve many resources. (Seeking source 081117)

Von Thunen::

r = Y(p − c) − YFm

where R=land rent; Y=yield per unit of land; c=production costs per unit of commodity; p=market price per unit of commodity; F=freight rate; m=distance to market.

Locational rent, a term used by von Thünen in his argument, is to be understood as the equivalent to land value. It corresponds to the maximum amount a farmer could pay for using the land, without making losses. It can be defined as the equation below:

L = Y(P − C) − YdR

* L: Locational rent (in Money / m²)
* Y: Yield (in Units / m²)
* P: Market price of the crop (in Money / units)
* C: Production cost of the crop (in Money / units)
* d: Distance from the market (in m)
* R: Transport cost / Resistance / Friction (in Money / units / m)

Stewart:: Demographic Gravity:

F = (N1 X N2) / ( √d )
Demographic Force = (population 1 X population 2) / (distance squared)

E = (N1 X N2) / d
Demographic Energy = (population 1 X population 2) / distance; this is also Zipf’s determinant:
Interchange of value; Y value of goods exchanged; inter-community movement of goods (by value):
Y = (N1 X N2) / d

PEN1 = N2 / d
Demographic Potential Energy of population 1 = population 2 / distance

PE = N / d
Demographic Potential Energy @ point = population / distance, in persons per mile

Gradient = N / m²
Demographic Gradient = persons / (mile squared)

Force of Diversity: economy of population living at source of raw material production (saves transport to production centre); n+, N-
Force of Unity: Economy of living together in one big city where all production done (saves transport to consumers); n- (to 1), N+ (to 100%)
Conflict of economies: n number of different communities and N sizes;

Reilly’s retail gravity equilibrium::

Population 1 / (distance to balance, squared) = Population 2 / (distance to balance, squared)

Larger cities will have larger Sphere of Influences than smaller ones, meaning people travel further to reach a larger city.

BP = d / (1 + ( √ (m²1 / m²2))

The balance or Break Point (BP) is equal to the Distance (d) between two places, divided by the following: Unity or Total (1) plus the Square Root of, the size of Place One (p1) divided by the size of Place Two (p2).

Notional gravity can be influenced by a number of things, but square footage is simple and effective measure of utility, ceteris paribus.

Zipf::

Interchange of value; Y value of goods exchanged; inter-community movement of goods (by value):

Y = (N1 X N2) / d

The movement of goods by value – and of persons – between any two communities, N1 & N2 that are separated by the easiest transportation distance, d, will be directly proportionate to the product, N1 X N2, and inversely proportionate to the distance, d. (The “Principle of least effort”)
