Urban Agriculture and biodiversity

Did you know that recent studies show that urban ecosystems present a higher richness of species than intensively managed agricultural ecosystems?  This could suggest that the conditions in the cities are giving these species a place to live without the threats of pesticides, disturbance from machinery or clear cuts after harvesting… isn’t that great? our cities are giving biodiversity a home!

With a growing population, the food demand will also increase. And maybe using urban spaces for food production could be an alternative to avoid agricultural intensification and enhance urban biodiversity. Boom! what a combination! 😉Lettuce

Cuba is an example worth mentioning…Evidence shows that the country has 8000 agro-ecological gardens managed without any chemical pesticide or fertiliser. Such gardens promote the diversity of crops and species, recycle and uses local inputs, and produce considerable amounts of food. In the case of La Habana city, these agro-ecological systems provided with 8500 tons of food, including 7, 5 millions of eggs, and 3650 tons of meat in 1996. Not bad right?

In a pot, in a garden or in an allotment close to your place…lets’s do it!


Urban biodiversity conservation

Why bother with urban biodiversity? … I can mention at least four reasons for knowing, caring and doing something to protect  all the species in our cities….

1.- cities offer an enormous niche and an opportunity for biodiversity conservation

2.-  urban settlements are inevitably growing in size and density and are one of the major threats to nature conservation.

3.- cities tend to be located in important biodiversity hotspots

4.- urban ecosystems provide a platform for citizens to understand the natural processes that govern global sustainability and provide them with several different social and psychological benefits.

Wanna do something about it? Get involved in urban planning and development in your home city! There is a lot of room for biologists, ecologist and conservationists in general. For example, green infrastructures such as green roofs and walls for food production, carbon sequestration, regulation of temperature could be the perfect scenario for the restoration of ecosystems, and the reintroduction of some native plants, birds, small mammals, insects that otherwise would not have a chance to co-exist with cities. It is true that many native species won’t resist to urban conditions but such technologies have the potential to restore the ecosystem’s functioning and to reconnect cities with the natural cycles.

Hope and innovation for conservation

There are great examples of successful conservation and sustainability efforts around the world that give us hope (Balmford, 2012; Bernard, 2010) and demonstrate that things can get better and will get better.IMG_0880 However, it is time to be honest in tackling the root causes of the problem from a conservation perspective.

Waste and our current consumption and production patterns are the major drivers for biodiversity loss, pollution, poverty, climate change (Orr, 1994).

What if we think  out-of the box for substituting something with nothing (Pauli, 2010)? and we create solutions that move away from pollution and waste and that use the resources that we already have?

The Blue Economy (Pauli, 2010) is a great example  showing that it IS possible to do so. In a nutshell, Gunther Pauli proposes the use of the waste produced by the coffee industry to grow mushrooms to feed vulnerable communities. Producers could grow coffee in a way that is compatible with biodiversity and responsible with the producer’s wellbeing. Responsible coffee drinkers could pay a fair price to producers, and in addition, new entrepreneurs could use the coffee waste to grow mushrooms to feed people (Pauli, 2010). The result would be that we wouldn’t need more land to grow more coffee or more resources for the creation of more goods, more jobs and more money. Check out more about this idea here.

With the same reasoning , there are many other examples of innovation in conservation. It is essential that we keep innovating our actions to tackle waste, production and consumption in the Anthropocene era (Steffen et al., 2011).  Keep checking the blog!!! new ideas coming soon… 🙂
