Summary of ¿Biodiversidad o dominancia en la producción de alimentos? | Lucas Garibaldi | TEDxBariloche

00:00:00 - 00:15:00

In his talk, Lucas Garibaldi discusses the importance of biodiversity in food production and how we are losing this diversity due to our reliance on a few crop species. He then presents four cases of biodiversity loss in food production, with the worst situation being one with few pollinizers. He argues that we need diversity in our crops to produce more food, and that we are heading towards a negative cycle where we are losing biodiversity and producing less food. Solutions that producers, consumers, and scientists can take action on include bringing back biodiversity in our fields, promoting crop diversity with shrubs and trees, and protecting remaining natural habitats that support pollinator populations.

• 00:00:00 Lucas Garibaldi, a researcher studying food production and the environment, discusses the importance of diversity in agriculture and the problem of dominance, which is when a single species dominates an ecosystem. He discusses how monocultures, which are farming practices that rely on a single type of crop, led to the loss of biodiversity and the replacement of it by dominance. He talks about how we are losing biodiversity and what we can do to prevent this, including replacing dominance with diversity in our food production.
• 00:05:00 In his talk, Lucas Garibaldi highlights the importance of biodiversity in food production, and how we are losing this diversity due to our reliance on a few crop species for pollen. He then presents four cases of biodiversity loss in food production, with the worst situation being one with few pollinizers. The next two situations are better, as there are bee species that rely on flowers with both male and female parts. The third situation is the best, as there is a mix of wild and domesticated pollinizers. The last situation is jade, which has a mix of wild and domesticated pollinizers. Garibaldi argues that we need diversity in our crops to produce more food, and that we are heading towards a negative cycle where we are losing biodiversity and producing less food. Solutions that producers, consumers, and scientists can take action on include bringing back biodiversity in our fields, promoting crop diversity with shrubs and trees, and protecting remaining natural habitats that support pollinator populations.
• 00:10:00 In his talk, Lucas Garibaldi discusses how biodiversity and dominance in food production are important topics to consider. We find that it is key to conserve habitats and expand production when crops were located further from natural pollinators. When farms were left unattended, they were providing a valuable service to food production, known as "amigable practices" with pollinators or "friendly practices" with the environment. These practices are friendly to both humans and the environment, and are known as "intensification ecologically." In contrast, conventional intensification, which often leads to more production, less diversity in biology, and impacts on all aspects of life, is an important topic to consider. Consumers can make a difference by reducing their waste and choosing more homogeneous fruits and vegetables.
• 00:15:00 In his talk, Lucas Garibaldi discusses the importance of biodiversity and argues that, as consumers, we can become producers by replacing dominance by one species with a more diversified approach to agriculture. He also points out that, due to the pressure to reduce consumption in an era of dwindling resources, we are learning a lot about ourselves and what we can do to help preserve biodiversity.
