Dutch eco-technologies in arid zones: autonomous water, controlled microclimate and biodegradable plant incubators

Global climate change and extreme heat waves are forcing the international community to rethink approaches to reforestation and agronomy in arid regions. The traditional concept of permanent artificial irrigation of desert areas is recognized as economically inefficient and environmentally dangerous due to the depletion of underground aquifers and secondary salinization of soils.

The modern approach is based on the principles of local microclimatic engineering. Instead of trying to change the macrosystem, innovations focus on creating autonomous points of viability for each individual plant. The leading role in this direction is played by Dutch developments, which have demonstrated high efficiency in harsh desert conditions.

1. SunGlacier system: generation of atmospheric moisture from renewable energy

One of the most talked-about technological demonstrations in recent years was the Netherlands Pavilion at Expo 2020 Dubai. The complex functioned as a closed climate ecosystem, the heart of which was the development of SunGlacier – a technology for autonomous distillation and collection of moisture from atmospheric air (Atmospheric Water Generation, AWG).

Technological parameters and results:

• How it works: Unlike conventional air conditioning systems that use huge amounts of energy to cool the air to the dew point, SunGlacier is based on patented heat exchange processes powered exclusively by solar panels. The system is capable of absorbing moisture even at extremely low relative humidity (20–30%) typical of desert locations.
• Productivity: During the six months of the World Expo, the plant extracted over 150,000 liters of clean water from the dry desert air. On the most productive days, the generation exceeded 1,200 liters per day.
• Practical application: The resulting water was used to create artificial internal “rain”, which naturally lowered the temperature inside the pavilion, and also fully ensured the irrigation of food and ornamental crops integrated into the architecture. You can learn more about the concept of sustainable pavilions on the official website Netherlands and you.

2. Cocoon cocoons from Land Life Company: a targeted start against permanent irrigation

If SunGlacier technology solves the problem of finding an autonomous source of fresh water, then Land Life Company’s Cocoon development meets the challenge of efficiently distributing that moisture. It is a biodegradable water-efficient tree incubator designed for planting in poor, rocky and arid soils.

The mechanism of operation of the bioincubator:

• Construction: Cocoon is a rounded hollow tank (“donut”) made from pressed cellulose, agricultural waste and natural waxes. The construction is fully biodegradable and leaves no plastic or chemical residue in the substrate.
• Capillary feeding: A young seedling is placed in the central opening of the incubator. The tank is filled with a fixed volume of water (about 25 liters) immediately upon planting and hermetically sealed with a top lid to prevent evaporation. Special wicks slowly, at a capillary level, transport moisture directly to the tree’s root system during the first few months – the most critical period for survival.
• Stimulation of deep rooting: The logic of the incubator is not to provide the tree with water throughout its life, but to create a protected starting microclimate. Limited but stable basal moisture stimulates the root to develop vertically downwards, into the deep layers of the soil to natural aquifers, rather than growing horizontally near the surface in anticipation of anthropogenic irrigation.

The use of such incubators allows you to increase the survival rate of trees in degraded regions from the standard 10–20% to 85–90%, completely eliminating the need for further costly maintenance and regular water supply.
