Background information

The world has several challenges that we’ll have to solve in the 21st century. The problems that we face are connected and integrated. Therefore, we believe it necessary to focus on an integrated solution for the challenges that we believe mankind faces nowadays. They are: erosion, deforestation, desertification, poverty, food crisis, unemployment; child labour, rural-urban migration, climate change and water scarcity.

In order to solve these challenges, mankind needs the solutions of thousands and the hard work of millions to implement them. There is not one solution for all these problems, on the contrary, we need an integrated approach of all the available solutions in order to solve the challenges. So, we need solutions for energy, against diseases, to produce more food, to create jobs, and so on. Groasis will focus on a small part of the spectrum of needed solutions that can help alleviate the challenges. We call this part the Treesolution. There is approximately 2 billion hectares of degraded farmland available. Planting productive trees in combination with growing vegetables in this area of degraded farmland can help combat erosion, create the production of saleable products, help produce approximately 5 to 10 tonnes of food per hectare, disconnect approximately 15 tonnes of CO₂ per hectare, create approximately 1 direct and 1 indirect job per hectare, can help revitalize the rural areas and this way diminish migration and change the soil into a sponge, stimulate the harvest of rainwater.

The Treesolution in combination with all the other thousands of solutions, will help us to combat the challenges.


Groasis aims to cause the reforestation of 2b hectares of manmade deserts – we call this the Treesolution - by developing and implementing cost-effective solutions that are commercialized as the Groasis Ecological Water Saving Technology. We do this because we want to help reduce poverty, ensure everyone has enough food, create jobs and wealth. Groasis will take the responsibility to do its utmost to help the implementation of the Treesolution to be successful during the 21st century.


Groasis will take any action that is necessary to help implement the Treesolution. It means that we will focus on causing the replanting of the mentioned 2 billion hectares of degraded farmland with productive trees and vegetables. 

Groasis has created 5 rules to reach her Mission:

  1. Strive to develop the Groasis Ecological Water Saving Technology in such a way that planting a tree will not cost more than 7 USD per tree, including training, the tree, vegetables and tree protector against grazing animals and a +95% survival guarantee;
  2. Groasis will always try to develop working methods that stimulate social welfare of the citizens living in the areas where the Groasis Ecological Water Saving Technology is and will be used;
  3. Groasis will not cooperate with projects where land grabbing is part of the business model;
  4. Groasis will help develop all talents of its personnel in order to make them feel happy while working to reach the Mission and Vision and do its utmost to let them earn sufficient for their families;
  5. Groasis will found the Green Musketeer Fund to help reach the Mission.

Groasis is a socially active and environmental friendly enterprise from Holland that is founded in 2003 by Pieter Hoff. Pieter Hoff was a lily breeder and an exporter/importer of bulbs. For his work, he travelled across the globe and he saw many problems. Almost all his clients were using drip irrigation and were complaining about the declining water table, more and more areas were the victim of deforestation and there were more manmade eroded and dry lands than ever.

He did not only think about the eroded, dry and wastelands, he thought also about the water shortages in the world. The UN states that already 700 million people in 43 countries are suffering from water shortages. At this moment we are using around 70 to 80% of the fresh water for agricultural purposes. We need this fresh water to drink. Besides the water shortages in the world, the world population is increasing. Will there be enough water to produce enough food in the future?

Pieter Hoff started to think about a solution how we can plant productive trees and produce food in a water saving way. There had to be a way to raise more awareness and to let people use water in an efficient way. He found the solution, sold his lily company and started to concentrate on the development of the Waterboxx® plant cocoon. After the Waterboxx® plant cocoon, other products were developed to plant trees, shrubs and vegetables in the most effective and water saving way as possible. In the end, you can plant with success with the Groasis Ecological Water Saving Technology and we are working hard to reforest the 2 billion hectares of wastelands in such a way that it is affordable for everyone.

Change wasteland into productive land

You can change wasteland into productive land while creating capital growth with the Groasis Ecological Water Saving Technology. While you use the Waterboxx® or Growboxx plant cocoon, you will use 90% less water than traditional irrigation methods (drip irrigation). Pieter Hoff has made the products of the Groasis Ecological Water Saving Technology in such a way that you don’t need any gardening knowledge. The products are easy to install and use!

You can use the Groasis Ecological Water Saving Technology for the planting of economical and ecological interesting trees. You can plant – for example – orchards and earn money on the trees, or you can plant for ecosystem restoration purposes. The trees can be planted in any climate and any soil. With the Groasis Ecological Water Saving Technology you use cost saving mycorrhizae and organic matter instead of expensive fertilizers to feed your plants.

The Groasis Ecological Water Saving Technology can be used by small farmers (planting fruit trees in combination with vegetables), corporate companies, NGO’s, investors or governments (greening up cities, minimize the effects of a sandstorm). Anyone who is interested to make degraded and eroded land valuable again, can use it.

While planting with the Groasis Ecological Water Saving Technology, you get a +90% survival rate without using irrigation. The costs are approximately 2 to 4 USD per tree (box, seeds, water, etc.). With a quick estimated calculation, you can calculate the costs of your project.
