CAMPINAS, Brazil, July 4 (Reuters) - Louis Dreyfus

Company, one of the world's three largest coffee merchants,

estimates that Brazil could add 23 million 60-kg bags to the

market over the next 10 years, the firm's head of coffee

research, Charles Chiapolino, said on Friday.

That would come after the South American country, the

world's No.1 producer and exporter, increased output by 9

million bags in the last decade, he added during a presentation

at the Coffee Dinner & Summit event.

Chiapolino noted that global demand for coffee remains

resilient even after it hit record prices earlier this year.

Brazil still faces some challenges to increase production,

including logistics, he added.

In the face of climate change, he said that the solution for

Brazil should be investing more in irrigation, as was done in

Espirito Santo state, which faced a drought last year but did

not report major problems.

"If you want to be resilient, you have to be prepared in

terms of global warming," he said.
