Conservation easements (or conservation covenants) are commonly conceptualized as acquisitions of sticks in a ‘bundle of rights’ and are increasingly implemented for wildlife conservation on private lands. This research asks: (1) What are the possibilities and limitations of the conservation easement approach to wildlife conservation in contrasting rural and periurban regions? and (2) How does analysis of conservation easements differ when examining property as a bundle of rights or alternative metaphors?

Increasing world population and the depletion of natural resources due to imbalances in development necessitates a new approach to development and the use of natural resources. Controlled adaptive planning, design, and judicious management of these precious resources seem to be a more logical approach towards resource conservation and sustainable development. This requires careful consideration and understanding of all attributes of a proposed site in order to suggest the appropriate form of development that will be in harmony with existing natural forces acting on the site.

In the conditions of the Republic of Belarus there was presents an organization of agricultural use of lands contaminated by radioactive elements. There were shown theoretical bases of the main problems forming the components of a complex project of intra-farm land usage.

Excessive loading of sediment and nutrients to rivers is a major problem in many parts of the United States. In this study, we tested the non-parametric Seasonal Kendall (SEAKEN) trend model and the parametric USGS Quality of Water trend program (QWTREND) to quantify trends in water quality of the Minnesota River at Fort Snelling from 1976 to 2003.

Context. Mismanaged fire is one of the main processes threatening biodiversity in northern Australian savannas. While the suite of species adversely affected by fire has been quite well documented, empirical studies that seek to identify the ecological mechanisms that underpin these declines are rare. This dearth of mechanistic knowledge is hindering the refinement and development of conservation management practices and policy, such as early dry-season prescribed burning programmes. Aims.

Cultivating annual row crops in high topographic relief waterway buffers has negative environmental effects and can be environmentally unsustainable.

In an era of global climate change, the agricultural sector faces the challenge of increasing the production of safe and nutritious food supplies to meet a growing world population while safeguarding the environment. Farmers will adapt their agricultural practices to a changing climate to safeguard against loss of production and to take advantage of any positive climatic conditions.

Preventing the establishment of saltcedar in new areas requires early detection and rapid response. However, it is unclear when saltcedar develops perennating tissue and which treatments are most efficacious for young plants. The effectiveness of mowing, herbicide, and fire treatments, alone and in combination, was evaluated on saltcedar plants grown from seed to 4, 8, and 12 wk age in 2011 and 6 and 12 wk age in 2012. Plants were clipped to 2 cm height or remained intact.

Irrigation is a widely used water management practice that is often poorly parameterized in land surface and climate models. Previous studies have addressed this issue via use of irrigation area, applied water inventory data, or soil moisture content. These approaches have a variety of drawbacks including data latency, accurately prescribing irrigation intensity, and a lack of conservation of water volume for models using a prescribed soil moisture approach.

Agricultural land use and the management of agricultural lands in Ghana as evidenced fromfarmer practices have been analysed using descriptive and regression analysis. The analysisshows that different land management practices affect crop yields differently in the differentecological zones. Also, the types of land management practices farmers use differ across thedifferent ecological zones. The policy implication is that agricultural interventions should bedeveloped on the basis of agro-ecological zones, and blanket crop improvement packagesshould be avoided.
