The most dynamic component of the conservation movement in the United States for the past three decades has been land conservation transactions. In the United States, land conservation organizations have protected roughly 40 million acres of land through transactions. Most of these acres have been protected using conservation easements. Climate change threatens the vast conservation edifice created by land conservation transactions. The tools of land conservation transactions are, traditionally, stationary. Climate change means that the resources that land conservation transactions were intended to protect may no longer remain on the land protected. Options to purchase conservation easements (OPCEs) have long played a modest but important role in conservation law practice. In the world climate change is creating, with its substantial uncertainties and shifting windows of opportunity, OPCEs can serve more complicated and strategic purposes. The ability of OPCEs to serve important roles in protecting land in the context of uncertainty would be significantly increased if state legislatures amend current conservation easement statutes to (1) specifically recognize OPCEs, (2) immunize OPCEs from a range of potential common law challenges, (3) guarantee the durability and transferability of OPCEs, and (4) integrate OPCEs into the burgeoning body of conservation easement law. These statutory amendments would do for OPCEs what conservation easement statutes have done for conservation easements: transform them into an essential multi-purpose tool for conservation in a changing world.

The United States Department of Agriculture employs soil and water conservation programs to assist with the sustainable use of natural resources in balance with economic vitality in rural America. This capstone project analyzed soil and water conservation programs to identify strengths, weaknesses, and methods to maximize environmental benefits. There are many requirements for participation in these programs which are difficult for most agricultural producers to comprehend. Research indicates in order to accomplish the goals of federal conservation programs and assist individuals, a method must be developed to effectively present information in a concise manner. This capstone project created a communicative measure, a template, to disseminate pertinent knowledge on soil and water conservation programs, thereby filling a void in existing literature.

The proposed Endangered Species Act listing of the gopher tortoise has the potential to impact the military mission at installations in the southeastern United States. Candidate Conservation Agreements with the U.S. Fish and Wildlife Service could be a tool to promote conservation and potentially preclude listing. This project identified military activities that could be affected and determined that military natural resources managers are unsure if such an agreement would prevent impacts to the military mission or impose the same restrictions as federal listing. This project found that if a gopher tortoise Candidate Conservation Agreement can be developed such that it benefits the species as well as the military, it should be used as a model for other species.

The Denver metropolitan area is facing rapid population growth that increases the stress on already limited resources. Research and advanced computer modeling show that trees, especially those in urban areas, have significant environmental benefits. These benefits include air quality improvements, energy savings, greenhouse gas reduction, and possible water conservation. This Capstone Project applies statistical methods to analyze a small data set of residential homes and their energy and water consumption, as a function of their individual landscape. Results indicate that tree shade can influence water conservation, and that irrigation methods can be an influential factor as well. The Capstone is a preliminary analysis for future study to be performed by the Institute for Environmental Solutions in 2007.

In the tropics, bats are an essential component of many native ecosystems, through providing various ecological services including pollination and insect pest control, in addition to seed dispersal. Many Philippine bat species roost in caves and underground habitats. However, many caves are disturbed by people, to exploit resources for food, recreation, and mineral and guano extraction. The misunderstanding of the importance of bats to the ecosystem is also considered a threat to many cave roosting species. Understanding the conflicts between humans and ecosystems which provide essential services is important to maintain ecosystem service provision. A total of 100 local respondents from the village of Pisan, Kabacan North Cotabato in south central Mindanao were interviewed through semi-structured interviews and focus group discussions. Respondents were asked about their views, levels of knowledge, use, interaction, and awareness towards both the caves and bats in their locality. Our survey found that most of the respondents are aware of the presence of bats from the caves in their locality. Unfortunately, a large proportion of the respondents noted that bats are hunted in caves for bush meat and trade, and most people perceived bats as pest to fruit crops such as durian. These factors are among the main factors of the execution of many bat colonies in caves of south central Mindanao. In general, cave bats are under appreciated species in caves. The unregulated tourism, hunting for bush meat and trade, and guano extraction are among the alarming threats occurring for both caves and bats in the locality and possibly to other localities in the country. Furthermore, the establishment of strong and effective model conservation education programs and the strengthening the participation of local government, academic, and community are essential steps to preserve the current state of cave bats in the area.

This study aims at assessing the socio-economic and environmental effects of different societal and human development scenarios and climate change in the water-scarce southern and eastern Mediterranean. The study develops a two-stage modelling methodology that includes an econometric analysis for the southern and eastern Mediterranean region as a whole and a detailed, integrated socioecological assessment focusing on Jordan, Syria and Morocco. The results show that water resources will be under increasing stress in future years. In spite of country differences, a future path of sustainable development is possible in the region. Water withdrawals could decrease, preserving renewable water resources and reversing the negative effects on agricultural production and rural society. This, however, requires a combination across the region of technical, managerial, economic, social and institutional changes that together foster a substantive structural change. A balanced implementation of water supply-enhancing and demand-management measures along with improved governance are key to attaining a cost-effective sustainable future in which economic growth, a population increase and trade expansion are compatible with the conservation of water resources.
