Like students, plants give up after years of failure, too

“The plant life of Australia’s outback may have “given up”, according to satellite-based maps tracking the impact of changing climatic conditions, such as rainfall and temperature, on the world’s ecosystems.

“The study suggests the vegetation of our interior does not respond to sudden increases in rainfall because it has “learned” that drought will soon follow. . . .

“‘Sometimes when you subject an ecosystem to some kind of disturbance, such as a drought or fire, they behave differently depending on their past,’ he explained. . . .

“‘They don’t care if it is good favourable conditions now, because they know it is temporary and it is not worth investing in growing more at this time because they become bigger and it is a lot more to care of when the drought returns,’ he said.”

Strong Social Networks Create Resiliency

“It’s not just that money can buy more sea walls, drought-tolerant agriculture equipment, private water supplies, and other material aids to adaptation. It’s that money also tends to come along with social capital, and one of the most important findings in research on resilience is that social cohesion is just as important as technology. It is the places with strong social networks that tend to have plans, civic institutions, early warning systems, and systems of aid and support that help communities through crisis.

It is socially cohesive communities, in which people are “in it together,” that survive disaster and rebuild afterward. Places without those social networks fragment; their suffering becomes a self-reinforcing cycle.

Unfortunately, economic inequality also tends to reduce social cohesion, leading to lack of trust and fewer shared resources. So if the people who support adaptation were being honest, they would acknowledge that perhaps the first and most effective form of adaptation is to reduce economic inequality, to create more cohesive communities defined by fellow-feeling rather than mutual suspicion and resentment. That’s true on the local level and also on the national and international level, as resource transfers between and within countries will need to rise markedly to prepare the most vulnerable places for what’s to come.”
