The System of Rice Intensification (SRI) is a group of agronomic management practices and principles which delivers optimum conditions for rice plants to manifest their fullest potentials for growth and yield.  This climate and enviroment friendly method of rice cultivation uses 50 percent less irrigation water, requires 90 percent less seeds and allows for the cultivation of rice using only organic inputs with zero chemical or synthetic fertilizers.  

SRI ensures that farmers in the group all use the same protocols or method of cultivation, use the same seed varieties and prepare organic inputs using the same formulas and use them in the same dosages.  These ensure that quality of rice grains are consistently of high quality and of the same organic integrity from farmer to farmer. 

Additionally, organic SRI plants exhibit substantial root architectures which allows them to withstand long periods of drought or extreme bouts of wind and rain.  The deeply entrenched roots also allow for maximum uptake of nutriens and water as well as allows the rice plants to sequester deeper in the soil horizon, organic and photosynthetic carbon.  The use of intermittent irrigation also lessens emissions of methane as a Green House Gas and the non-use of fertilizers reduce carbon emissions.

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.

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. 

The first community garden was built by Mr. Temp and his brother on their own initiative on a plot of vacant urban land in front of Temp's house in São Paulo's East Zone.

Both have experience in organic agriculture: His brother runs their great-grandfather's farm in Agudo in the South of Brazil, and Temp, after having studied business management in Rio de Janeiro (1985-88), completed a two-years course in organic agriculture on a farm in Tübingen, Germany (1993-95). 

The garden area had been abused as a dumping site. When neighbours saw the garden being built there instead, they became aware of and interested in this alternative kind of landuse. A group of people got together to help and to replicate the implementation of gardens. Temp guided them.

Today, having implemented 25 community gardens, he considers guidance crucial for the success of the gardens. Furthermore, this guidance needs to be continuous and intensive especially in the first year of a garden's implementation. Afterwards, community gardeners are able to manage their garden autonomously, but it is important for Cities Without Hunger to be present as contact persons and to lend bigger machines when needed. 

Before he founded Cities Without Hunger, Hans Dieter Temp had worked as project coordinator in the city of São Paulo's public administration, supporting the creation of the Secretaria de Relações Internacionais da Prefeitura de São Paulo, the mairy's secretary for international relations. He found that the effort put into administrative tasks could do little to tackle the actual problems of local people in 

the city districts, because the city administration was lacking staff responsible for such tasks, and because residents were lacking basic prerequisites to improve their situation. He wanted to close this gap and to be present on-site as coordinator to support the local network. In December 2003 he quit his job at the city administration and began the foundation process of Cities Without Hunger.

The producer family with their garden is always linked with a broader sphere, such as the relationships between gender and generations, the social organisation, community, local and international markets, the cultures, and – something often overlooked as important – religion and/or spirituality. These aspects, however, should be considered within the concept of training.

The proposed methodology is based on a period of intensive theoretical and practical training of local trainers (facilitators) and lead farmers. In addition, the participants must "rebuild" their knowledge on their own plots of land. Individual practice must be supervised and accompanied by a senior trainer experienced in Dynamic Agroforestry.

Lead farmers present their practical know-how and document the processes experienced in the following installation period. In this way, a practical implementation of the concepts worked on can be achieved within a concrete context for the production level of a rural family. 

Upscaling is achieved as followed:

- 1 local trained facilitator trains 10 lead farmers

- 10 lead farmers accompany 5 to 10 farmers each in implementing DAF

- 10 trainers accompany 100 lead farmers

- 100 lead farmers  = 500 to 1000 followers

In addition to improving overall conditions related to increasing temperatures, the city of Stuttgart has designed an innovative project “KlippS – Climate Planning Passport Stuttgart” based on quantitative findings in urban human-biometeorology, for improving human thermal comfort. The KlippS project calculates the human thermal sensation under “warm” category during the daytime in summer. KlippS is divided into two phases: the first phase is concerned with a rapid evaluation of human heat stress for the areas involving “sustainable building land management Stuttgart”, the second focuses on numerical simulations at high-risk urban areas related to heat.
 

KlippS provides the following remarkable issues on a planning-related potential to mitigate local human heat stress:

a) innovative program involving the human-biometeorological concept which represents a new interdisciplinary field

b) various spatial scales including the both regional and local ranges on the basis of the systematical two-phase method

c) quantitative approach to human heat stress by using dominant meteorological variables such as air temperature T, mean radiant temperature MRT and thermophysiologically equivalent temperature PET

A preparatory land use plan (PLUP) was undertaken, which organises land into its building and other types of uses and includes green areas and corridors. This PLUP is not legally binding, but serves as a basis for planning and information.

The land use plan developed in 2010 contains essential components for sustainable urban development, envisaging urban development under the slogan "urban─compact─green". Its guideline is for brownfield rather than greenfield development in a 4:1 ratio. It aims to protect green areas and develop a green network through brownfield areas.
