Aquaponics: Sustainable Farming for Urban Slums

Aquaponics: Sustainable Farming for Urban Slums in South AmericaAquaponics is a sustainable solution to food insecurity and economic instability in urban slums. It combines aquaculture (raising fish) and hydroponics (growing plants in water), creating a closed-loop system where fish waste provides nutrients for plants and plants help filter and clean the water for the fish. In South America, countries like Brazil and Peru are implementing more aquaponics, improving their economy and reducing poverty.

Urban Slums

Urban slums in South America encounter significant challenges, such as food insecurity, unemployment and poor nutrition. A report by the United Nations (U.N.) reveals that nearly 20%, which is more than 130 million people, live in slums across Latin America, where they struggle with limited access to basic services and job opportunities. Many face financial instability, with little to no savings or access to credit. The impact of poverty and food insecurity leads to widespread malnutrition and health issues, especially among children, due to a lack of access to proper sanitation or even clean water. Additionally, the lack of job opportunities perpetuates the cycle of poverty, making it difficult for residents to improve their living conditions.

Aquaponics

Aquaponics is a highly efficient and sustainable solution, using up to 90% less water than traditional agriculture and requiring minimal land space – a perfect fit for densely populated urban areas. It enables year-round food production, reduces reliance on external food sources and creates local employment opportunities. The most common type of fish used is tilapia and the most common plants are leafy greens. With its controlled environment, crops thrive, resulting in better quality and higher yield. A study by SpringerLink found that in aquaponics, more than 50% dedicate less than 10 square meters, with some using larger areas. Notably, more than half of respondents did not receive technical advice, relying instead on web pages, books and acquaintances for information. This goes to reveal how easy and accessible this practice is. 

Brazil

In São Paulo, Brazil, the NGO Cidades Sem Fome has undertaken aquaponics projects in multiple urban slums. These initiatives have proven to be highly successful in addressing food insecurity by providing local communities with sustainable access to fresh produce and fish. In addition to significantly contributing to improved nutrition, these projects have also played a crucial role in improving the lives of residents. Through training programs and the creation of employment opportunities, the projects have also fostered the development of valuable skills.

Peru

In Lima, the Peruvian government, along with local NGOs like Cooperar Peru, has initiated aquaponics projects to enhance food security in urban slums. INMED Andes has also set up an aquaponics system in the indigenous community of Yarinacocha to provide a consistent food supply for the local school students and surrounding households. These initiatives have proven successful, offering a reliable source of nutrition, generating employment opportunities and safeguarding often overlooked Indigenous communities. These projects have had a significant positive impact on the community’s health and economy, revealing the potential of aquaponics as a sustainable solution to urban poverty.

Government and Private Sector

Government policies are crucial in promoting aquaponics. In Brazil, for example, government grants and subsidies, such as the Inovagro program, have helped establish aquaponics systems in urban slums. Private sector investment in aquaponics projects has also contributed to their success by providing capital and expertise. While aquaponics systems are cheaper and easier to maintain, they do require a high initial capital investment. 

Various programs and initiatives in South America, such as the “Huertos Urbanos” program in Peru, aim to establish urban gardens using aquaponics in slum areas. These programs have facilitated collaboration between different stakeholders, ensuring the sustainability and scalability of aquaponics projects.

Looking Ahead

Aquaponics provides an effective strategy to combat poverty and improve food security in urban slums across South America. Its benefits include sustainable food production, water conservation and economic opportunities. Successful initiatives in Brazil and Peru demonstrate its positive impact on local populations. With continuous support, aquaponics has the potential to significantly reduce poverty, boost nutrition and empower communities in urban slums, making it an essential part of a more sustainable South America.

5 Nonprofits Fighting Poverty in South America

5 Nonprofits Fighting Poverty in South America More than a quarter of Latin America’s population faces low income and a scarcity of food and resources, highlighting the critical role of numerous nonprofits dedicated to combating poverty across the continent. In South America, poverty disproportionately affects women, Indigenous peoples and rural communities, prompting many organizations to specifically target vulnerable groups experiencing poverty in the region. Here are five nonprofits fighting poverty in South America:

RedEAmérica

This foundation creates partnerships between powerful businesses and organizations in Latin America to promote the exchange of ideas and resources to promote sustainable living and the development of local communities. RedEAmérica is based in 11 countries in the Caribbean and Latin America and has secured more than 40 partnerships across the regions. Its primary focus is collaborative knowledge to solve problems in climate change, education and gender issues. 

South American Initiative

The South American Initiative is a U.S.-based organization founded by Steven Malca. It provides food and medical aid to vulnerable groups in South America like children, babies, mothers and senior citizens. Malnutrition is the first cause of illness and death for infants, hence why its work is so important. Through its work, the South American Initiative has distributed almost 250,000 meals to those in need. In addition, the organization has many programs based in Venezuela specifically. It targets orphans, refugees and hospitals. For instance, the SAI Medical Clinic for Children helps youth avoid lifelong health conditions by ensuring they receive proper nutrition and medical aid.

Fundación Corazón Raíz

This Mexican organization primarily focuses on foundational education programs for children and youth. Its work is based on six pillars: solidarity, justice, confidence, respect, coherence and transparency. La Casa de la Mujer Indígena (translated to “The House of the Indigenous Woman”), one of its successful programs, empowers women in Indigenous communities to pursue educational opportunities and economic security. Another one of the Fundación Corazón Raíz’s initiatives is the Gayela Children Foundation, which provides housing, food, medical attention and access to education to children without families.

Nuestros Pequeños Hermanos

Nuestros Pequeños Hermanos is a nonprofit that helps children in poverty and disadvantaged circumstances in Central and South America, as well as the Caribbean. The organization has several other initiatives focused on health care and security. For instance, the Dental Care for Our Children program helps establish good dental hygiene by educating participants on the importance of a healthy dental routine.

Another initiative is the NPH Peru One Family Program. It helps children without parental care or those at risk of losing theirs, through family awareness programs that help kids become aware of their options. The program also facilitates family reintegration with follow-up support. Overall, Nuestros Pequeños Hermanos has been highly successful in providing aid to children, as seen in its past yearly reports. For instance, in 2022, more than 3,300 children from low-income households were sent to school.

Ayuda en Acción

Ayuda en Acción is a nonprofit that provides intervention throughout infancy and adolescence to disadvantaged youth through educational and economic programs. With more than 600 beneficiaries and programs in 20 countries, the organization hopes to create greater food security and peaceful conflict resolution in communities across South America.

Since its founding, Ayuda en Acción has provided more than 30,000 youth with access to education. Many of its initiatives are region-specific. For example, in Bolivia, the nonprofit helps Indigenous youth lead development in their communities to improve production and create new employment opportunities. In El Salvador, another program fortifies protection for children experiencing gender-based violence and supplies emotional and psychological care to those impacted by the COVID-19 pandemic.

Looking Ahead

Nonprofits across South America are tackling poverty by focusing on the needs of vulnerable populations, including women, Indigenous communities and rural residents. Organizations such as RedEAmérica, the South American Initiative, Fundación Corazón Raíz, Nuestros Pequeños Hermanos and Ayuda en Acción provide crucial support through education, health care and food security initiatives. Their ongoing efforts can potentially enhance the quality of life and promote sustainable development throughout the region.
