The various land management and planning policies that have been developed for the Tierra de Campos district of northwestern Spain over the past century have had major effects on wetland ecosystems of this area. To assist conservation planners in the future management of these habitats, this study outlines the changes that have occurred in these environments using data for the years 1900, 1956, 1984 and 2007. Multiple logistic regression models allowed the accurate projection of locations of wetlands that need to be restored or regenerated.

Why do many smallholder farmers fail to adopt improved land management practices which can improve yields and incomes? The reason is not always because these practices are uneconomical but sometimes it is because resource poverty prevents farmers from taking advantage of yield and income enhancing agricultural practices. In this study we examine the relative merits of using a carbon payment scheme compared to a subsidy policy to help reduce the cost of specific land management practices with productivity and ecosystem benefits such as carbon sequestration.

Government agencies in many countries are encouraging rural landholders to improve their land management practices in order to improve the health of the natural environment. The level of adoption of improved practices by landholders is, however, highly variable. Understanding the diversity of rural landholders is an important step in increasing the uptake of improved land management practices. In this study, we investigate the factors that influence landholders to adopt recommended practices and use this to provide insights into how to encourage greater adoption of these practices.

A number of studies have dealt with the assessment of potential and actual desertification risk using composite indices. The Environmental Sensitivity Areas (ESA) approach, developed in the framework of MEDALUS project funded by the European Community, is one of the most used procedures to monitor land vulnerability to degradation in the Mediterranean region. The final output of this procedure is an index (ESI) composing four indicators of climate, soil, vegetation, and land management based on 14 elementary variables.

Living and detrital biomass in a riparian buffer zones ameliorate diffuse-source pollution originating from adjacent landscapes, with higher nutrient removal potential, particularly with respect to nitrogen and sediments, associated with more biomass (i.e., older forests). Pollution removal is mediated by sediment trapping and uptake of nitrogen by plants and by denitrification by microbial communities in root zones using organic matter and root exudates as energy sources.

The importance of soil storage in global carbon cycling is well recognised and factors leading to increased losses from this pool may act as a positive feedback mechanism in global warming. Upland peat soils are usually assumed to serve as carbon sinks, there is however increasing evidence of carbon loss from upland peat soils, and DOC concentrations in UK rivers have increased markedly over the past three decades.

Pricing greenhouse gas emissions is a burgeoning and possibly lucrative financial means for climate change mitigation. Emissions pricing is being used to fund emissions-abatement technologies and to modify land management to improve carbon sequestration and retention. Here we discuss the principal land-management options under existing and realistic future emissions-price legislation in Australia, and examine them with respect to their anticipated direct and indirect effects on biodiversity.

The objective of this paper is to contribute to progress in the choices of strategies for further development of goat farming in the 21st century. During the last 20 years, the number of goats around the world increased (by about 60%) not only in the countries with low income (75%) but also in those with high (20%) or intermediate (25%) income.

While numerous scientific publications have used biological data and sometimes decision theory to identify where conservation funds should be invested, studies that examine where money for conservation actually has been spent and how investment patterns have changed through time are scarce. We analyze changing spatial patterns of spending on land protection, using investments by a major conservation organization, The Nature Conservancy (TNC), in the conterminous United States as a case study.

Long-term records from USDA Forest Service Experimental Forests and Ranges (EF&Rs) are exceptionally valuable scientific resources and common ground for research in natural resource management. Coweeta Hydrologic Laboratory, Southern Appalachian Mountains in western North Carolina, is one of 82 EF&Rs located throughout the United States and Puerto Rico.
