Підсумок	Real options valuation applies the theory of financial options to real (physical, strategic) investment decisions, valuing the managerial flexibility to defer, expand, contract, switch, or abandon a project as uncertainty resolves over time. Where standard discounted-cash-flow analysis assumes a now-or-never commitment to a fixed plan, real options recognize that managers hold rights — not obligations — to act, and that this flexibility has value precisely because the future is uncertain. Using option-pricing and dynamic-programming methods, the approach values these embedded options and identifies the optimal timing and conditions for exercising them.	Ecosystem Services Valuation (ESV) is a framework pioneered by Costanza and colleagues (1997) that assigns economic value to the benefits nature provides to humanity—from pollination and water purification to climate regulation and cultural enjoyment. Formalized in the Millennium Ecosystem Assessment (2005) and The Economics of Ecosystems and Biodiversity (TEEB 2010), ESV bridges ecology and economics to make the invisible value of ecosystems visible to policymakers and markets.
