I love challenges and I believe that big results are achieved starting from small actions. The Greenhouse Challenge gave me the right input to set up a team and share a goal: develop innovative and inclusive solutions for urban food supply.

As a coordinator of a 17-member team, I am responsible for the integration of the four topics of the competition: Social inclusion, economic feasibility, food production and design.

TEAM coordination and process facilitator

Taking part in the Urban Greenhouse Challenge as part of the Green Spark team enables me to to work alongside a multicultural team which can investigate societal, business and technical limitations in the field of urban agriculture and propose implementable solutions. Due to my multidisciplinary background I will work alongside the team coordinator, Andrea, in integrating the ideas of all subgroups and ensuring smooth coherent communication to guarantee a productive and creative design process. I truly believe that by working together with perspectives from different cultures and disciplines it is possible to solve some of the worlds largest challenges, in this case: providing sustainable lifestyles for the ever-increasing city citizen.

By participating in the Urban Greenhouse Challenge, I want to focus on the aspect of social inclusion as I think is of a pivotal importance to provide new meeting points for people, especially in the cities. Amsterdam in particular, offers an interesting and multicultural environment where diversity can become a powerful starting point for social inclusion and education. As a consequence, people can learn by different cultures; learn again traditional knowledge about food production and processing, as well as enjoying simpler life shared within a community. Furthermore, people can gain more awareness about food production (and consumption), waste management and energy production in order to create a new and a more committed future society, which will care about topics as climate change mitigation, nature conservation and equity.

As a student of Communication Science I am driven by the mission to improve peoples’ life by the
practice of right listening, right seeing and right speaking. When Hegel points to the Zeitgeist in all
nations, I point to the Zeitgeist in all cities, originated
by everyone and no one. In that matter, city
development is a very special topic to me:
Depending who is listening a city can become both a place of harmony or disharmony. All revolution started with a new forum to speak, so (maybe) to archive a Green Revolution, we just need to image new spaces. Here, I believe that Urban Greenhouses provide an unseen opportunity, not only for local food production, but also for the empowerment of local communities.
Urban Greenhouses can become forums, where people speak, get to know each other, in order to harmonize their voices. Alone we are small, but together we can think tall.

Creating support amongst citizens for sustainable developments in cities is one of my main goals. As I am from a big city myself, I noticed how important it is to make the connection between urbanites, food production and the environment but also between different social groups. I hope to contribute to this aim by participating in the Greenhouse Challenge and being part of the social team.

I believe that bad externalities of the current food system in the planet are caused by the ignorance of (mostly urban) consumers, who dissociates themselves from that production. Urban farming not only benefits the environment in terms of carbon footprint or land saving but also in an education that may transcend just food habits to become healthy habits at all leves. My ambition is to be able to help in bringing this change into reality. I think that no one can envision one's place in the world without understanding where the food that they eat three times a day comes from. There is no better way to learn this than trying to design a food production facility, in this case where is most needed: a urban greenhouse. Doing this in a multi- cultural and disciplinar team of a Challenge is an unique oportunity to do this.

Agriculture is at the foundation of our society. It influences so much, from our environment to our health and cuisine. When I was 16, I started a hobby of growing plants at home using hydroponics, and since then, my interest in producing high-quality food in a resource-efficient way has only grown. As a student in biosystems engineering, the Greenhouse Challenge is a fantastic opportunity to apply my skills and learn from others’ backgrounds.

My motivation for joining the Greenhouse Challenge is to establish a less wasteful and more circular system for food production and food consumption. My background is as an ecologist in California -- a State where agriculture is a primary economic driver and a source of food throughout the world. The UN predicts that the global population will reach 9.6 billion by 2050, many of which who will be living in urban areas; this, magnified with the existing 88 million tonnes of food waste generated annually in Europe alone is reason alone for more efficient, streamlined, and creative urban agriculture to come to fruition.

Growing up in Costa Rica  gave me a strong connection with my surroundings, nature, and people. During my bachelors in agriculture I discovered the possibility of growing food in cities and how this represents a solution to many of our metropolitan challenges. I’m an urban agriculture enthusiast, my goal is to work within the urban agriculture scope to improve the outflows and surpluses of the urban systems, while supporting food security for people and having a positive impact on all possible levels, from aesthetics of the urban landscape to the mentality of city dwellers that feel disconnected with nature and the production of food. The Greenhouse Challenge is a great opportunity to grow and learn from my peers while working on a hypothetical but realistic tool for Amsterdam’s current foodscape state.

What really ticks me is being able to contribute in topics which provide solutions to the biggest challenges in our human and natural environment. My ambition is to create an example that shows how the quality of life and well being can be improved in an urban environment. An example that creates new sustainable economic opportunities and improves food security. An innovative space that brings different interests together to create social, economic and environmental benefits for the community.


2017: MSc. Environmental Sciences

Trying to help solve a massive problem for mankind by creating innovative solutions already is very attractive. Doing so in an international, multi-disciplinary team makes up for the rest. By participating in the Urban Greenhouse Challenge I’m trying to discover the other end of agriculture from what my bachelor is focused upon. From smallholder farming in developing countries to high-tech farming in the center of a global metropole.

Many themes developed in relation to architecture were considered at a time unreal or futuristic, only through time they were realized. Based on the given data, I have a firm belief that urban agriculture developed through architecture practice has the potential to do an immense change in resolving food-related global challenges. The design challenge is literally a global think-tank to explore what we can reach until the moment.

Since we are living in bigger and bigger communities, we now have the problem of too less living space and of course we need more field for agriculture. Another way would be, importing food from other countries, but that is very expensive and bad for the environment.  So we have to find ways to grow our food on less space. One way is to use different floors in buildings and grow indoor. That leads also to a big biodiversity because you can influence the factors you need for the growing process.I like being part of this new stream and being part of something bigger than me.

My goal for this challenge is to change or to extend the thinking of our resources and the overall thinking about "not living in abundance". I think this simple mindset could contribute to a better world where all livings can live together in harmony and peace. And I am happy to get the chance to integrate and express my mindset and actively work on something all livings can benefit from. We were born in a world which is certeined by the older generation but now we have the chance to make a bigger green change for our future.
