Greenhouses have been built and produce crops in the hottest deserts now. They have climate and humidity control. They use 7% of the water to grow crops compared to open-air farming.

Climate Change is something to be minimized. However, climate change only impact open-air farming. All food production can be brought indoors where it will be virtually immune to climate change.

China is planning to have over 2 million hectares of greenhouse buildings by 2025 with mechanized-automation of farming. The Ministry of Agriculture and Rural Affairs Monday issued a guideline to promote the country’s facility-based agricultural planting, outlining goals for infrastructure upgrades and mechanization to boost output and farmers’ income. By 2025, China will maintain over 2 million hectares of facilities, including plastic greenhouses, and achieve above 50 percent mechanization for facility-based planting, a sector of the so-called controlled-environment agriculture (CEA), or protected agriculture.

The world already has about 500,000 hectares of climate-controlled greenhouses. China has 4 million hectares of crude plastic sheeting covering land in partially enclosed conditions. The plastic sheets lie over simple metal poles and crude framing.

IF there was a need, the entire world could bring all agriculture indoors and under temperature and humidity control by 2035.

China’s newer greenhouses maintain optimal growing conditions throughout the development of crops, and optimizes the use of resources such as water, energy, space, capital and labor. Production takes place within an enclosed structure, such as a greenhouse or building.

Robotic greenhouse buildings can be up to 30 times more productive than the same area of regular farmland.

China under non-emergency conditions will build climate-controlled greenhouses to replace 10% of open-air farm production every year. If needed it would take ten years or much less to bring all agricultural production globally into climate-controlled conditions that use 7% of the water.

Doomer scenarios about billions forced to move because of widescale farm and water problems or collapsing megacities are a bunch of crap.

Pure Harvest is a startup that built a one-hectare facility in the Abu Dhabi desert in 2018. The warehouse has since been producing around two tons of tomatoes a day, which are retailing for around $2 (8 dirhams) for 300 grams.

Growers can take full control of their ventilation efforts – meaning you no longer have to wait for just the right breeze to come along to keep your plants growing strong.

Ventilation plays a huge role in everything from temperature regulation to humidity mitigation, and regular airflow itself can actually be crucial to providing fresh CO2 so indoor plants can keep breathing easy.

For most modern growers, proper ventilation can be achieved through a combination of fans and vents built right into the wall of a greenhouse. By encouraging airflow on still days and closing up gaps to prevent airflow on windy days, you can more naturally regulate temperature, introduce or remove humidity, and keep plants well supplied with breathable CO2 to keep them growing strong all year long.

New systems use vapor pressure deficit controls for super-energy efficient temperature control. They bring up humidity as the temperature rises. Costs are 2 cents per gram for maximum controlled environment farming of marijuana. China’s large-scale controlled environment agriculture will be at far lower energy costs for mass agriculture.
