1/3

In the space of Forty years we shall have to build the equivalent of a 1000 cities of three million inhabitants

each to cater for the worlds population growthapproximately as many cities as there are today

(Mayor, et al. UNESCO: 2001).

Resilient Havana

Havana

Havana is home to some 2.14 million people (CIA, 2009). Its overall population density is 3,019

inhabitants per km because of the large amounts of open spaces that exist within the city (INV, 2002).

The city has put into place numerous policies to become more efficient and resilient.

1989 marked the end of the USSR. This was a period of great rejoice for the capitalist West but created a

period of unprecedented hardship for the countries that relied on the Soviet Union for trade, produce and

perhaps most importantly oil.

Almost overn ight Cuba lost 80% of its oil imports.

Havanas Change

Havanas resilience started in 1989 with the fall of the USSR. Cuba relied heavily on the USSR for

food, oil and products. The end of the USSR meant that the supply of these necessities ended almost

overnight.

Fidel Castro put into place the Special Period. This looked to adapting Havana to these changing

issues. This was seen by the Cuban government as the perfect time to make Havana as self reliant and

resilient to external factors as they possibly could.

Food For ThoughtFood Security

Havana is extremely unique in the way that it has tackled the issues of food production. After the

collapse of the Soviet bloc it understood that it could not continue to rely so heavily on food imports.

In order to tackle this localised, farming was put into place. Today more than 50% of the cities fresh

produce is grown within the city limits (Abitz, 2008). The reason for why this has occurred is the fact

that the Cuban government supported this agricultural action. It looked to putting in place land rights

for those who wanted to grow food. In 2002, more than 35,000 hectares (86,450 acres) of urban land

was dedicated to the intensive production of fresh fruits, vegetables, and spices (foodfirst, 2003).

Cuba and Havana have not only looked to becoming as self sufficient as possible when it comes tofarming it is also looking at reducing its oil dependency as well. Instead of the Green Revolution

model of using oil for farming Cuba went back to basics for instance, instead of using oil based

pesticides and herbicides Cuba uses natural means. More than 0.5 million tons of worm castings are

used per year in Cuban agriculture (Lotter 2003).

Havanas Energy Change

The massive decline on Cubas oil imports had a detrimental impact on the countrys economy and

energy production. Its energy production from oil-powered power plants dropped dramatically. The

1990s saw rolling blackouts and energy shortages.

It this because of this issue that the countrys energy consumption rates are significantly lower than the

rest of the world. Figure 1 shows that in 2002 the countrys power consumption per capita was 1,187

kWhs compared to the worlds consumption average of 2,441 kWhs.

Havana like other cities around the world has understood the risks of climate change and an almost sole

reliance on foreign energy sources. To overcome this issue the city has looked towards renewable and

sustainable energy solutions. Currently 7% of Cubas energy comes from renewable sources and further

biomass generation plants are being developed (Esencia, 2011). These biomass plants will burn

agricultural waste will help to make Havana more resilient to foreign energy prices.

(World Bank, 2012).

1.2 million bikes were bought from China and 500,000

made within Cuba itself. This reduced the countrys

dependency on cars and oil-based transport means.

Havanas Transport

The removal private vehicles. Instead mass

public transport systems were put into place.

These are designed to transport as many Cubans

around the city in the most fuel efficient way

possible. It looks to reducing the unnecessary

number of transports as much as possible.

Learning from Havana

To say that all the changes made within Havana in the name of sustainability are perfect and should be

followed by others is not true. However, a lot can be learnt from the actions of this city. For instance

the reduction in its reliance on oil not only means that it is more resilient to foreign energy market

prices but the citys pollution rates have decreased.

One of the most important factors that can be learnt from Havana is the importance of community.

Through communities the city has managed to grow 50% of its food needs within its limits. This not

only reinforces community spirits and a feeling of comradeship it also removes the reliance on oil that

once existed in the agricultural sector within Cuba. These measures show what cities can do to become

more resilient and prepare for the future.
