Colombian Scientists Predict Climate Change to Affect Most Food Crops

To CIAT. From Rio Branco - Acre - BRAZIL - West Amazon. Without a doubt there can be future food shortages in the near future keeping in mind that the World population continues to grow. But there is still a lot of land to cultivate crops, despite the real estate speculation. I would like to call the attention of the researchers, to pay attention to the famous American HAARP PROJECT that is now being put into practice. I would like to receive comments regarding this. What the agricultural technicians of CIAC tell us is amazing. I would like it if DIALOGO, using its contacts, began a campaign directed at South America in order to confront the problem before it is out of control and the dwarf becomes a giant. Encourage financial accounts in the domestic budgets from Mexico to Argentina to study and for see the problems of climate change, petition for satelite help from the Americans and Europeans in order to monitor the changes in vegetation and climate from space and research new seeds and investigative techniques. I ask that not only continue to act as informative agents, but that you become entities of ACTION and CHANGE for the good of the people.
Thank you
An international agricultural research institution in Cali, Colombia is conducting a study into the effects of climate change on the world’s top crops. The study by the International Center for Tropical Agriculture is scheduled for release later this year.

For generations, rich Colombian mountains have produced a variety of food crops, beans, cassava and notably coffee. But local coffee farmers say the weather is changing, and so are crop yields. Carmen Eneida Trujillo is worried. “Look, there are not too many coffee flowers around here; this is a sign that the weather is already damaging the crop,” she said.

Eneida says until a few years ago, this plantation would be loaded with white flowers in September, announcing a good harvest. Her husband, Elias Claros, says they are already considering other crops. “I believe we won’t be able to plant coffee here for much longer,” he said.

More than a million people in Colombia grow and produce coffee, a crop sensitive to climate change.

And what they are experiencing now is what scientists at the International Center for Tropical Agriculture, or CIAT, in Cali, have forecast for some time — climate change is changing agriculture. Many traditional crops will have to move to other regions.

“Essentially, the geography of agriculture is likely to change significantly, so where you grow maize today may not be the same areas in the future. In temperate regions, crops are moving north. Here in Colombia is more across the elevation, so it moves upwards, in the mountains to greater altitude,” said Andy Jarvis, who is in charge of the climate change and policy program at CIAT.

CIAT is conducting a study about the impact of climate change on 50 of the world’s major crops, including rice, maize and wheat. Jarvis says every region of the world is experiencing different climate change, from extreme heat or drought to cold and flooding.

“In the past, the bamboo would have troubles at 2,000 meters, but now is growing and adapting well to higher altitude,” said Carlos Arturo Trujillo, who has been a farmer all his life.

Some scientists are increasingly concerned about food security, especially for the poor.

“We are finding large scale producers are just as susceptible to unexpected, uncertain highly variable weather patterns as the small holders. Small holders are much more vulnerable because they have less access to knowledge and information in the right time and the right place,” said Erick Fernandes, an adviser on climate change and natural resource management at the World Bank in Washington.

However, he says large farmers have more access to information and insurance that help them mitigate the impact. “Work done recently by Stanford University researchers have projected that for southern Africa where maize supplies a huge amount of the calories for the poor, by 2030, relative to 1990 production, there may be as much as 30% negative impact on maize productivity,” he said.

Researchers expect crops in Africa, Asia and Latin America to suffer greatly over the next few decades and they also expect extreme temperatures to contribute to land degradation and an increase in agricultural pests. Meanwhile experts predict that in order to feed the world’s growing population, agriculture will need to nearly double its production by the year 2050.
