Heat, droughts and an Indian Feast

20 Jan

I’ve been neglectful over the past few weeks. I should have had lots of time over to post during the quiet Christmas . I thought that I would be incredibly sad, missing family and friends but it felt like such a different world and such a different experience that it was hard to correlate the hot weather and sunshine with Christmas Day. And Christmas Day was hot…the thermometer hit 43.2 C across Rio, the highest ever recorded temperature. We decided it was the perfect day to cook an Indian curry! We surrounded the table with four fans as an attempt to try and keep cool, it didn’t stop the sweat dripping.

An Indian Feast on Christmas Day in Brazil

An Indian Feast on Christmas Day in Brazil

Its amazing the lethargy that the heat brings on, the imperative to slow down, lie down, rest, sleep early and the difficulty to generate enthusiasm and excitement to think, communicate, do new things. But this heat is not just a personal challenge. The North East of the country has been suffering the worst drought in 30 years, the amount of milk produced in many states has dropped by 40 – 50% with many animals dying. Friends visiting the Chapada Diamantina near Salvador recently walked along dry riverbeds, in the rainy season! Around 90% of the electrical energy used in Brazil is hydroelectricity. The drought has resulted in low levels of the reservoirs, down to 28-30% of normal levels across the country, a decrease in energy production and a tripling of the use of thermal power plants. Attempts to ensure the continuity of electricity supply by opening the floodgates at hydroelectric plants is depleting the reservoirs even faster. At the same time the high temperatures cause an increase in energy consumption as the use of air conditioning rises. Electricity prices will continue to rise, where inflation was already at 7.8% last year, as well as CO2 emissions.

This has coincided with droughts across the world, particularly in North America, resulting in much higher soybean and corn prices. The result of this, lots of farmers in Brazil switching to growing soybean and corn instead of other crops such as cotton, rises in land prices and huge pressure to convert more land to agriculture.

Its a worrying and vicious cycle if the effects of a changing climate, decreasing agricultural yields and rising food prices just results in the conversion of more land for agriculture, increased habitat destruction, emissions from land-use change and the loss of carbon sinks.

Thankfully the rain has now returned to Rio…abnormally so, with temperatures closer to that of the winter. But I’m not complaining. The fans are silent and our energy has returned!
