"Geoengineering" refers to planetary-scale engineering projects which attempt to influence global properties. In theory, the term "Geoengineering" could refer to any planet, but it is most frequently use to refer to engineering of the planet Earth. Geoengineering is used to describe projects that involve Teraforming Earth - and making the planet more habitable.


  • Ocean reclamation - the world's oceans represent ecological wildernesses. The main problem is that all the food sinks to the bottom - where there is no light and plants cannot grow. Ocean reclamation aims to fix this problem - by either turning oceans into land, surfacing them over or skinning them for farming purposes, using aquaculture techniques. "Deep" ocean reclamation iis also possible, though it is more challenging and further off into the future.

  • Desert reclamation - some of the world's equatorial regions have baked. They badly need irrigating on a large scale.

  • Tundra reclamation - the earth is currently in the middle of an ice age - and much of its large northern landmasses are frozen wastelands. Tundra reclamation aims at improving this situation.

  • Irrigation - water supplies are of critical importance to plant and animal health. Constructing reservoirs by building dams helps supply fresh water. Rainfall can be stimulated via cloud seeding, or via increasing evaporation.

  • Mountain reclamation - some of the planet is too high off the ground. The air is thin, and plants do not grow well. Mountains cause clouds to empty themselves - and create dry areas in their "precipitation shadow". Unfortunately, mountain reclamation looks as though it will be difficult and expensive.

Some related techniques:

  • Earthquake amplification - seismic stimulation can be used to amplify and prolong small earthquakes can help to avoid big ones.

  • Cloud control and the weather - attempts to influence precipitation may help irrigate the planet in the future, and may have power to help avert extreme weather conditions.

Human systems are typically supported by a "grid" which supplies electricity, gas and information. At a pinch, information can be supplied wirelessly - but the electricity and gas grids are pretty fundamental infrastructure whose extent needs to be expanded.

The problems, geoengineering faces are technological, political and economic. All these aspects will need addressing before geoengineering can become more widespread.
