Three smallholder villages located in typical communal (from 1948), old (1987) and new (2002) resettlement areas, on loamy sand, sandy loam and clay soils, respectively, were selected to explore differences on natural resource management and land productivity. Focus group discussions and surveys were carried out with farmers. Additionally, farmers in three wealth classes per village were chosen for a detailed assessment of their main production systems.

Several long-term agroecosystem experiments (LTAEs) across Canada have been maintained for periods of up to a century. Much scientific knowledge of changes in soil properties through time has been learned from these few, highly productive LTAEs. We determined the effects of land management changes (LMC) on soil organic carbon (SOC) by re-sampling 27 LTAEs across Canada using identical sampling and laboratory protocols.

The International Commission on Irrigation and Drainage (ICID), a global network organization with 106 member countries in its fold, is dedicated to the promotion of best practices in water for agriculture, and addresses water supply and management for food production, including drainage and flood control. While striving to improve water and land management, and enhancing the world supply of food and fibre, ICID takes on board environmental concerns and seeks sustainable solutions.

Like many fishes native to western Great Plains streams, the Arkansas darter Etheostoma cragini has declined, apparently in response to changes in flow regimes and habitat fragmentation. We investigated the effectiveness of translocation as a management strategy to conserve this threatened species in the Arkansas River basin of southeastern Colorado.

Increasingly, landowners are establishing hardwood plantations to satisfy their land management goals. Unfortunately, little is known about how competition control affects initial seedling survival and subsequent investment returns for hardwood plantations. This study examines five alternative competition control regimes for southern oak establishment. The regimes include no site preparation, disking only, sub-soiling with rotary mowing, herbicides only, and herbicides with rotary mowing and sub-soiling.

Land use, land use change and forestry activities play an important role in determining whether soil is a sink or source of atmospheric carbon dioxide (CO₂). The effects of land use change on greenhouse gases and climate change are receiving greater attention in many developing countries. We simulated changes in soil organic carbon (SOC) pool over 100 years (1950-2050) under managed dense Shorea forest (DS), rainfed upland (Bari) and irrigated low land (Khet) of Pokhare Khola, a mid-hill watershed of Nepal, using the Century model.

Question: Small and marginal forest populations are a focus of attention because of their high biodiversity value as well as the risk of population decline and loss. In this context, we ask to what extent a small, marginal Quercus suber (Cork oak) population located in the eastern Iberian Peninsula (Valencia, Spain) has the capacity for self‐regeneration and what are the factors that determine its recruitment variability. Location: Quercus suber forest in Pinet (Valencia, Spain).

Willingness to pay (WTP) estimation typically involves some strategy for mapping nondichotomous contingent valuation (CV) responses onto a dichotomous yes/no dependentvariable. We propose a new approach to selecting which responses qualify as ‘yes.’ We apply the proposed method to polychotomous CV data for preventative land management programs in the Great Basin. We also estimate WTP using other methods of response recoding found in the literature.

Protected areas are regarded as the most important tool in the conservation toolbox. They cover > 12% of the Earth's terrestrial area, with over half of this designated since 1970, and are thus a unique example of governments and other stakeholders consciously changing management of land and water at a significant scale. The Convention on Biological Diversity (CBD) has a global programme to complete ecologically-representative protected area networks, and this is driving the creation of large numbers of new protected areas.

The fate and turnover of microbial carbon (C) in an arable soil following crop residue addition likely depends on the quality of both native soil organic matter (SOM) and residues. We labeled the microbial biomass with ¹³C-glucose and followed the microbial ¹³C turnover into different SOM pools under the influence of three plant amendments (mature wheat, immature wheat, and vetch) in a laboratory incubation experiment using a soil with two different contents of organic C (0.9 and 1.3 %) owing to different soil management.
