California Institute of Environmental Design & Management (CIEDM), a California based conservation grassroots, is engaging actions in a single program to provide local supports and participation in two global awareness campaigns that are closely related to each other in the end of July 2026. The two observances are World Nature Conservation Day (WNCD) and Earth Overshoot Day (EOD), respectively, on July 28 and 30. Not only they both are observed globally and close in time, but also they are inter-related on their shared campaign goals and objectives – Conservation of natural resources and ecosystems – which is coincided with the missions of CIEDM. We thereby have developed and carried out the action program to celebrate the global campaigns and to raise public awareness and actions for them. WNCD, established by the International Union for Conservation of Nature (IUCN) in 1997, is about protecting natural resources, preserving biodiversity, and maintaining a healthy environment for future generations on this planet. EOD, similarly, marks the date when humanity’s demand for natural resources and services in a given year exceeds what our planet’s ecosystems can regenerate in that year. Based on footprint and biocapacity factors, calculation by Global Footprint Network reveals that the global wide EOD for 2026 falls on July 30, and warns that human consumption of natural resources beyond that date is at risk. With CIEDM serving as a Partner for the IUCN Nature For All, a global initiative to inspire people to love, connect with, and care for nature, and myself as a member of the IUCN Research Taskforce and Inter-commission Human-nature Connectedness (HNC) Task Forces, we are compelled to take lead-by-example actions and share with others as to what concerned citizens and grassroots can do for natural conservation. Our voluntary community engagements for WNCD and EOD through this last week of July and beyond include such components as online campaigning and knowledge sharing, public policy advocacy, capacity and network building, in-person gardening and yard maintenance works, and hybrid community/citizen science engagements.
