Nature provides a vast array of goods and services for free to people — from clean water and air to places of recreation and spiritual significance — however, the value of these services is rarely taken into account in decision making process because no economic market exists for these benefits. The emerging framework of ecosystem services is an attempt to better understand and, if possible, quantify the flow of nature’s goods and services so that managers can better evaluate trade-offs when making complex decisions that affect the environment. Part of the this framework involves the development of “ecosystem market mechanisms” where landowners are financially compensated for keeping their lands healthy and functioning so that they will continue to deliver ecosystem services, such as the provision of fresh water to downstream users, the sequestration of atmospheric carbon dioxide, or pollination of agricultural crops. SIG helps clients in every stage of the process of implementing ecosystem service-based decision making, from initial scoping, to detailed analytics, to market mechanism development, to communication with stakeholders. SIG can help clients integrate ecosystem services and natural infrastructure values into their decision making process by offering the following services:
