The text you quoted is certainly a part of the support for "optimism," clbrogesr. I'd say it's also generally found throughout the passage. The author has described a problem, and is telling us about a solution. We're told that experts are searching for a way to solve the problem, which is optimistic in itself (they aren't ignoring the problem, but are aware of it and actively seeking to solve it). We're told that a recent study has confirmed the value of heirloom crops for solving the problem. And we're told that it is a viable solution, because heirloom varieties have been preserved, they can adapt well to resist pests and reduce the need for intensive practices like irrigation, and the knowledge of how to use them has also been preserved. This is a passage filled with good news!
Thus, "optimism" is supported, even if we cannot be absolutely assured of success. The author seems to think heirloom crops will be the answer that the experts have been looking for.
