The Groasis Ecological Water Saving Technology consists of 5 building blocks:

1) Growboxx®/Waterboxx® plant cocoon

​intelligent bucket

Provides water to a tree and vegetables while creating a healthy micro-climate. Both boxes use 90% less water and provide a survival rate of +90%.

2) (Bio)Growsafe Telescoprotexx

protects plants

Plant protector against heat, frost, wind, (sand)storms, and grazing animals. Protects plants and speeds up to plant growth. Available in carton or polypropylene.

3) Growmaxx Mycorrhizae

assists and/or replaces fertilizer

Fungi that feed the plant and support a healthy root system. Fertilizers contain salt and in dry soil often burn the roots. Mycorrhizae replace expensive fertilizers (natural alternative) while supporting faster plant.

4) Capillary Drill

elevates planting productivity

Machine used to accelerate making planting holes while leaving the capillary system intact. Digging planting holes by hand takes 15 min/hole (32 – 40 holes/day). Capillary drill makes 6.000 holes per day.

5) Terracedixx

increases water infiltration

Machine is used to make mini-terraces to stimulate increased rainwater infiltration into the soil. Currently just 25% of (rain)water enters the soil in degraded areas, by using the Terracedixx up to 90% is harvested.

Ensuring that farmers are able to competitively supply food to any future home-grown school meals programme, or other institutional market, will be essential for improving livelihoods and generating broad-based health and economic growth. Currently, the guarantee of a steady supply of fresh vegetables remains a challenge and schools are accustomed to purchasing food from one or more larger traders following government guidelines for contracts and bidding processes. Trainings provided through the Farmer Business School on sustainable agricultural practices and the provision of certified seed have helped farmers scale up their production levels for indigenous vegetables, while guidance on gross margin analysis and bidding processes has increased farmer skills in contract negotiation and in determining an equitable price for their produce. Prior to the training, a limited number of farmers had attended market and value addition trainings, expecting third parties to undertake market searches on their behalf. Following the training, farmers were more confident about going out to seek their own markets, particularly after learning that institutional markets were open to purchasing indigenous vegetables to increase dietary diversity for their beneficiaries and to improve nutrition.

Enterprises are most successful when they leverage strong community involvement, collaborate with a local conservation organization, and are dedicated to the conservation of wildlife. Forming strong partnerships and avenues of communication on the ground ensures that certification benefits local communities and incentivizes the protection of biodiversity.

The Wildlife Friendly Enterprise Network offers a range of certification programs that promote best practice standards for farming and ranching enterprises around the world. These standards represent global best practice with input from the appropriate experts to ensure that a) key species of wildlife are protected for net positive impact and b) local communities are actively involved.

CAMGEW provided the various cooperatives with equipment and materials to enable them to function better. The materials included beehives, honey drainers, honey harvesting containers, beesuits, bee smokers, honey storage containers and honey packaging containers.The cooperatives needed material for honey harvesting and storage, and equipment to drain honey. CAMGEW gave them basic equipment and material to promote a smooth start-off. The various cooperatives have to care for additional material and equipment on their own. There are other institutions that could assist the cooperatives. To access those, CAMGEW supported cooperative leaders with training on management skills. CAMGEW created 5 new cooperatives in the Sub-Divisions of Belo, Njinikom, Jakiri and Fundong. One cooperative existed already in Oku for more than two decades, contributing much experience and success stories. The new cooperatives are learning from the existing one through exchange visits.

The high level of cultural and biological diversity of the Cuyabeno Wildlife Reserve attracts thousands of local and international tourists every year. It’s important to mention that the Reserve’s main natural attraction is a floodable lake system.

In the last years, the flux of tourists increased after the Government issued a National Decree in 2012 that eliminated any entrance cost to access any protected area in the country.

Another important factor was the investment done by the Government and some international cooperation agencies, to improve tourism planning and public infrastructure in the Cuyabeno Reserve, which reflected in better services for the Area’s visitors.

Also, the Ecuadorian Ministries of Environment and Tourism regulated the tourism activities inside the protected area, licensing tourism operators and developing actions to promote good practices linked to sustainable tourism.

The actions carried by both institutions in the last years, for example, promoted the design and implementation of management standards for sustainable tourism and an income increase for local communities.

CAMGEW uses apiculture to fight bushfires in Kilum-Ijim forest. Bee farmers have been producing honey with no market, due to poor quality and the fact that it is difficult to collect honey produced by individual farmers. CAMGEW decided to organize bee farmers into Oku White Honey Cooperatives to develop quality and quantity of Oku White Honey and its products like bees wax. Through these 5 new cooperatives and existing ones, the quantity and quality of Oku White Honey will be improved to satisfy consumers and meet standards. The honey is certified as Geographical indication product. It will become easy to access and assist bee farmers and market their produce. Oku White Honey is the brand name of honey produced from the Kilum-Ijim forest in Cameroon that covers two Divisions (Bui and Boyo) and 5 Sub-divisions (Oku, Jakiri, Belo, Njinikom and Fundong). The forest covers three tribes (Nso, Oku and Kom). Kilum-Ijim White Honey Association (KIWHA) is the umbrella association for the promotion of Oku White Honey. The bee farmers groups in each village act like family bee farming groups where adults teach the young bee farmers to prepare future bee farmers. Women engage in bee farming with their families to increase family income or as individuals.

When implementing a new community garden, Cities Without Hunger offers agricultural training courses to the people interested in becoming community gardeners. Those selected for the projects are often domestic migrants who have come from rural regions to the city in search of employment but have little chances on the regular job market due to their age or education. They often have practical experience in agriculture, which facilitates their activities as community gardeners. Their knowledge is complemented by Cities Without Hunger's agricultural engineers, who train people to run urban community gardens. 

The implementation of a community garden of about 6000 square metres costs around 33 000 USD. This includes working devices (e. g. spades and hoes), irrigation system and sun protection, measures of soil improvement such as organic fertilizer and humus, construction timber for the compost heap and planting beds, plants, seeds, petrol for the delivery of materials and machines, and personnel costs for two agricultural engineers who help residents create the garden. Costs vary depending on the size of the garden. 

The implementation of the community gardens is financed through donations from private and public persons and foundations. In 2015, a German branch was founded in Berlin (Städte Ohne Hunger Deutschland e. V.) with the objective to support Cities Without Hunger's work in Brazil financially and public relations work abroad, especially in Germany, but increasingly at an international level. 

After one year, community gardens are self-supporting. Gardeners earn their income selling their produce. Cities Without Hunger still provides technical support and lends bigger machines like tractors when needed. The NGO also supports network-building actions to integrate the gardens in São Paulo's wider economy, e. g. through delivery partnerships with restaurants.

Vacant urban land is the essential building block required for the implementation of a community garden. The urban sprawl offers spaces where such gardens can be created. Areas include land below electricity lines, near oil pipelines, city-owned land, or private properties. 

Cities Without Hunger makes contracts with land owners on the use of the respective area. The land is given to the NGO for free. In turn, land owners can be certain that their land is going to be used as a community garden, avoiding the misuse of areas as dumping sites, and helping prevent wilful damage of infrastructures such as electricity lines or oil pipelines. On such areas, other landuses such as housing are prohibited. That way, landuse conflicts do not occur. 

Land use contractors include e. g. the energy supplier Petrobras, Transpetro, or Eletropaulo. 

With a growing number of community gardens and strong media presence within São Paulo and beyond, Cities Without Hunger earned a reputation as an NGO with who private and public land proprietors want to collaborate. Hence, getting access to new areas is usually unproblematic.
