How can public-private partnerships work for agroforestry? I've been sitting in on the Tompkins County Water Resources Council meetings for a few months now, and today I presented on Agroforestry and Water Quality. 1 acre of parking lot creates the same amount of flood runoff as 36 acres of forest – and it's only a matter of time before Ithaca gets Asheville'd (that's 0% alarmist and 100% candid). Buffers with trees in them absorb 4-5x as much nutrient runoff as grass alone, and Harmful Algal Blooms (HABs) really stymie the swimming suitability of Cayuga Lake. Ithaca is unique: it's Tompkins County's main municipality, and it has 6+ creeks flowing right into downtown. Flooding is a massive concern, and even with plans to dredge Cayuga Inlet (the choke point for flooding): "Green infrastructure upstream takes the strain off of grey infrastructure downstream." For the ecological economics nerds: Ithaca is ideal for monopsonistic payments for ecosystem services, which is one of the replicable ways society actually pays for nature. Pictured is a small riparian buffer we planted in Danby, on Buttermilk Creek, in one of the two highest-priority watersheds. The next step here is systematizing funding agroforestry for flood mitigation. My take is that a municipal green bond, backed by both PES and timber revenue, is scalable, highly replicable, and can be tailored to diverse local contexts. Open to feedback here, but otherwise: onward. Plant the trees.
