Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

And in a world of accelerating sea level rise and climate change, in which farmland is being degraded and turned to desert, in which ever more land is set aside for carbon storage in the form of forest, and in which the strains of survival increase social divisions and social conflict, there is a new challenge: where will the 2bn climate refugees find new homes?

This is the new face of the old threat — that new land - based mitigation techniques, such as biochar, bioenergy carbon capture and storage (BECCS) and other types of carbon dioxide removal (CDR) geoengineering approaches, as well as old «solutions» like biofuels, will compete with the use of land to feed people.

Biofuels and bioenergy take up finite land resources at the cost of food production and carbon storage and doesn't guarantee carbon emissions cuts.

Biological sequestration includes direct removal of CO2 from the atmosphere through land - use change, afforestation, reforestation, carbon storage in landfills and practices that enhance soil carbon in agriculture.

Comparing emissions from various fuel crops versus carbon storage in natural ecosystems, Renton Righelato and Dominick Spracklen write that «forestation of an equivalent area of land would sequester two to nine times more carbon over a 30 - year period than the emissions avoided by the use of the biofuel.»

Chapter 4 addresses the energy supply sector, including carbon capture and storage; Chapter 5 transport and associated infrastructures; Chapter 6 the residential, commercial and service sectors; Chapter 7 the industrial sector, including internal recycling and the reuse of industrial wastes; Chapters 8 and 9 the agricultural and forestry sectors, respectively, including land use and biological carbon sequestration; Chapter 10 waste management, post-consumer recycling and reuse.

By using three different models to address the problem, the researchers encompassed in their answers the variability in estimates of forest cover, carbon storage in forests and costs of land management.

There are a wide range of hypotheses about the dominant controls and key parameter values governing land carbon storage, and a parallel range of ways in which these hypotheses are implemented in the codes of land models.

Some forms of carbon removal are also subject to significant debate, such as whether bioenergy with carbon capture and storage (BECCS)-- which involves burning biomass like crop wastes for energy and capturing and storing the carbon emissions underground in geological formations — can be truly sustainable at a large scale given competing needs for land, among other concerns.

The research needs for predicting — across multiple scales — the impact of land use change and management practices to the future of terrestrial carbon storage and CDR potential

The most likely method of achieving negative emissions, biomass with carbon capture and storage (BECCS), is controversial because it might require very large areas of land to be set aside for fast - growing trees or other biomass crops.

A slight contemporaneous increase in 13C of atmospheric CO2 has led to the suggestion that this effect was caused by enhanced carbon storage on land (Francey et al., 1999b; Trudinger et al., 1999).

Developed countries push for a mitigation approach where they see agricultural land usage as a way to reduce emissions through false solutions like biofuels and bioenergy carbon capture and storage which reduce the amount of land we can use for growing food.
