Properties of a system that sup-port actors to cope with change,
to be adaptive and resilient.

• Supporting the ability of farmers to remain agile in responding to new challenges, by adapting their production system
• Resilience or adaptive capacity are proper-ties of the actors, sustainagility that of the system in which they function
• Resilience may indicate return to status quo, agility refers to continuously moving targets
• Sustainagility + Sustainability => Probability of meeting future needs
Sustainagility

The appreciation by local and ex-ternal stakeholders of the envi-ronmental services that remain-ing forest + agroforest patches provide tends to depend on how much forest is left, as well as the spatial pattern.

In forest-rich landscapes, forest functions are taken for granted at the local scale, even if they represent considerable value from a global perspective; in landscapes with little forest left, the environmental services of the remaining forest may be highly valued locally, but probably represent little of interest to global stakeholders (as sensitive species will most likely have disappeared).
![Page 19: Questions for multifunctionality symposium: 1. Where is the space for synergy in integrated multifunctionality? 2. Where are ‘hard tradeoffs’ unavoidable](https://reader030.vdocuments.mx/reader030/viewer/2022032708/56649e715503460f94b6f166/html5/thumbnails/19.jpg)
Following this logic, it is in interme-diate landscape mosaics that forms of ‘environmental service rewards’ will be needed, as external value exceeds local appreciation, while (supposing that loss of forest cover continues) conservation may in fact match future local appreciation.
