NATURAL CAPITAL - LAND
LAND is a critical constraint on the performance of the socio-enviro-economic system ... but almost totally misunderstood in policy making
Much of the land on planet earth is either desert or mountain and unsuited to human habitation. Some people in the modern consumer economy are using more than their fair share of the land to support their lifestyle. Land is being developed into urban conurbations and for industrial scale agriculture reducing the land that is available for natural ecosystem services critical for the sustainability of the enviro-socio-economic system.
The total land area of 200 territories is 13,056 million hectares. Divided up equally that would be 2.1 hectares for each person. A hectare is 100 metres by 100 metres. However, population is not evenly spread: Australia's land area is 21 times bigger than Japan's, but Japan's population is more than six times bigger than Australia's.

Land ... Wetlands ... TPB note:
I became aware of the importancve of mangrove and coastal wetlands early in my career when I was the CFO of an international shrimp company. In order for a shrimp fishing company to be financially sustainable there has to be a supply of wild shrimp not only this season, but into future seasons. The mangrove is a key part of the shrimp life cycle, and without a biologically healthy mangrove there will not be a financial future for the company. Accordingly I worked in a variety of countries on initiatives to maintain coastal wetlands. I left this role at Continental Seafoods in 1978 and I am appalled at the amount of coastal degradation that has taken place in the last 50 years mainly because of tourist development and shrimp farming in sensitive coastal areas!
Land ... Wetlands ... The New Jersey Meadowlands
The New Jersey Meadowlands is very valuable real estate very close to Manhattan, New York City. At the same time the Meadowlands are very valuable as wetland and part of the essential natural ecosystem for the Hudson River and local marine life. Prior to 1960s the land was also used as a dump for the solid waste from New York City. This was ended and then the area became toe site for commercial development including the Meadowlands Sports Complex. Subsequently the value of the Meadowlands as a critical wetlands has been recognized and ongoing built development restricted.

The business case for soil
Action on soil sustainability must move beyond the farm and into the boardroom, urges Jess Davies ... Nature-The-Value-of-Soil
Savanna covers approximately 20% of the Earth's land area. There are several variants of savanna.
Tropical and subtropical savannas are classified with tropical and subtropical grasslands and shrublands as the tropical and subtropical grasslands, savannas, and shrublands biome. The savannas of Africa, including the Serengeti, famous for its wildlife, are typical of this type. The Brazilian savanna (Cerrado) is also included in this category, known for its exotic and varied flora.
Temperate savannas are mid-latitude savannas with wetter summers and drier winters. They are classified with temperate savannas and shrublands as the temperate grasslands, savannas, and shrublands biome, that for example cover much of the Great Plains of the United States. (See areas such as the Central forest-grasslands transition).
Mediterranean savannas are mid-latitude savannas in Mediterranean climate regions, with mild, rainy winters and hot, dry summers, part of the Mediterranean forests, woodlands, and scrub biome. The oak tree savannas of California, part of the California chaparral and woodlands ecoregion, fall into this category.
Flooded savannas are savannas that are flooded seasonally or year-round. They are classified with flooded savannas as the flooded grasslands and savannas biome, which occurs mostly in the tropics and subtropics.
Montane savannas are high-altitude savannas, located in a few spots around the world's high mountain regions, part of the montane grasslands and shrublands biome. The lowland savannas of the Angolan Scarp savanna and woodlands ecoregion are an example.

GREEN INFRASTRUCTURE GUIDANCE for reducing the impacts of impervious cover on water quality
A total of 14 Major Habitat Types reflect the diverse array of organisms adapted to life on land. These habitats range from the wettest of forest types to the driest and hottest desert conditions. Moreover, terrestrial communities represented here include the full extent of continental topographic relief: from mangrove forests by the sea to the alpine meadows of the Himalayas.
