        <Description1Txt>Cooks Branch Conservancy, comprised of approximately 5,300 acres donated by the Mitchell family in 2011, promotes conservation ethics and demonstrates the resilience of nature in perpetuity, offering a rare glimpse into what a century of regeneration looks like in the East Texas Piney Woods. The transformation of the once clear-cut, overgrazed working ranch into an award-winning nature conservancy exemplifies extraordinary habitat management and wildlife conservation on private land.Heat and water stress associated with climate change is making forests more vulnerable throughout the world. Cooks Branch acts as a field laboratory for the study of such things as carbon flux, drought, ecosystem transition, biodiversity, and the effects of fire.The conservancy utilizes tools such as restoration timber harvests, prescribed burning, mechanical and chemical midstory control, invasive species eradication, and replanting in various combinations to meet specific eradication, and replanting in va</Description1Txt>

        <Description2Txt>Consistent with the sustainability science approach that characterizes the foundations grantmaking, the Water Program aims to increase the scientific understanding of water issues in the state of Texas, which informs the design of effective policy approaches to ensure that the water quantity needs of the environment are met. According to the 2012 State Water Plan, under certain conditions, Texas does not and will not have enough water to meet the needs of its people, its businesses, and its agricultural enterprises. To address these water management challenges and ensure adequate water supplies for the environment in Texas, the Water Programs resources are deployed to 1. Define the grand challenges of water management and the scientific, policy, and legal investigations necessary to address intractable questions; 2. Increase water conservation in major Texas cities through urban water conservation programs and utility business model reform; 3. Protect water resources in the Texas Hill</Description2Txt>

        <Description3Txt>The foundation focuses on improving the governance of shale development in addition to supporting efforts to reduce the negative environmental and community impacts of shale gas development.The unresolved challenges related to shale development and natural gas can be divided into two broad categories. The first set of questions involves natural gas as a fuel source, including to what extent fugitive methane emissions occur and how these emissions can be minimized and to what extent abundant natural gas displaces renewable energy and energy efficiency in electricity generation.The second set of questions involves the risk of impact from hydraulic fracturing and horizontal drilling to develop shale formations. These technologies have a distinct risk to the environment and communities, but these risks can be economically managed.The Shale Sustainability Program supports a number of solution-driven strategies, including: 1. Examination of the interplay between federal, state, and local gov</Description3Txt>

        <Description4Txt>The Mitchell Foundation is committed to clean energy in the state of Texas and supports strategic efforts that ensure that the states growing demand for power is both minimized and met with the cleanest and water-leanest sources of electricity possible. The foundation seeks to invest in initiatives that demonstrate a comprehensive understanding of Texass competitive electricity market structure and can leverage that knowledge to create innovative and effective energy policies that ensure reliability and resource adequacy while reducing the environmental and health impacts of power generation.To achieve its strategic goals, the Clean Energy Program supports: 1. Efforts to bring an array of diverse, centrist-thinking communities to bear on clean energy policy issues; 2. Policies and innovative mechanisms that increase cost-effective energy efficiency activities; 3. The development of renewable energy markets to help fill the gap in electricity supply; 4.

        <Description1Txt>The Mitchell Foundation granted a request by Texas Parks and Wildlife Foundation to provide a program-related investment loan at zero percent interest to the Gulf Coast Conservation Loan Fund. The loan is pooled with contributions from other funders and used to make loans to nonprofit land conservation organizations for the purpose of acquiring and holding properties of high ecological value, pending the disbursement of grants from Deepwater Horizon settlement funds which would enable their permanent protection. Support from the Mitchell Foundation was leveraged with public funding for a significant impact on conservation efforts.</Description1Txt>
