Worldwide, governments subsidize agriculture at the rate of approximately 1 billion dollars per day. This figure rises to about twice that when export and biofuels production subsidies and state financing for dams and river basin engineering are included. These policies guide land use in numerous ways, including growers’ choices of crop and buyers’ demand for commodities. The three types of state subsidies that shape land use and the environment are land settlement programs, price and income supports, and energy and emissions initiatives. Together these subsidies have created perennial surpluses in global stores of cereal grains, cotton, and dairy, with production increases outstripping population growth. Subsidies to land settlement, to crop prices, and to processing and refining of cereals and fiber, therefore, can be shown to have independent and largely deleterious effect on soil fertility, fresh water supplies, biodiversity, and atmospheric carbon.

Economics plays an important role not only in the management of national parks in developed countries, but also in demonstrating the contribution of these areas to societal well-being. The beneficial effect of park tourism on jobs and economic activity in communities near these protected areas has at times been a factor in their establishment. These economic impacts continue to be highlighted as a way to demonstrate the benefit and return on investment of national parks to local economies. However, the economic values supported by national parks extend far beyond local economic benefits. Parks provide unique recreation opportunities, health benefits, preservation of wildlife and habitat, and a wide range of ecosystem services that the public assigns an economic value to. In addition, value is derived from the existence of national parks and their preservation for future generations. These nonmarket benefits can be difficult to quantify, but they are essential for understanding and communicating the economic importance of parks. Economic methods used to estimate these values have been refined and tested for nearly seven decades, and they have come a long way in helping to elucidate the extent of the nonmarket benefits of protected areas.
In many developed countries, national parks have regulations and policies that outline a framework for the consideration of economic values in decision-making contexts. For instance, large oil spills in the United States, such as the Exxon Valdez spill of 1989 and the Deepwater Horizon spill of 2010, highlighted the need to better understand public values for affected park resources, leading to the extensive use of nonmarket values in natural resource damage assessments. Of course, rules and enforcement issues vary widely across countries, and the potential for economics to inform the day-to-day operations of national parks is much broader than what is currently outlined in such policies. While economics is only one piece of the puzzle in managing national parks, it provides a valuable tool for evaluating resource tradeoffs and for incorporating public preferences into the decision-making process, leading to greater transparency and assurance that national parks are managed for the benefit of society. Understanding the full extent of the economic benefits supported by national parks helps to further the mission of these protected areas in developed countries.

Coastal zone management (CZM) has evolved since the enactment of the U.S. Coastal Zone Management Act of 1972, which was the first comprehensive program of its type. The newer iteration of Integrated Coastal Zone Management (ICZM), as applied to the European Union (2000, 2002), establishes priorities and a comprehensive strategy framework. While coastal management was established in large part to address issues of both development and resource protection in the coastal zone, conditions have changed. Accelerated rates of sea level rise (SLR) as well as continued rapid development along the coasts have increased vulnerability. The article examines changing conditions over time and the role of CZM and ICZM in addressing increased climate related vulnerabilities along the coast.
The article argues that effective adaptation strategies will require a sound information base and an institutional framework that appropriately addresses the risk of development in the coastal zone. The information base has improved through recent advances in technology and geospatial data quality. Critical for decision-makers will be sound information to identify vulnerabilities, formulate options, and assess the viability of a set of adaptation alternatives. The institutional framework must include the political will to act decisively and send the right signals to encourage responsible development patterns. At the same time, as communities are likely to bear higher costs for adaptation, it is important that they are given appropriate tools to effectively weigh alternatives, including the cost avoidance associated with corrective action. Adaptation strategies must be pro-active and anticipatory. Failure to act strategically will be fiscally irresponsible.
