Development and validation of the global surface type data product from S-NPP VIIRS
Accurate representation of actual terrestrial surface types at regional to global scales is an important element for many applications.
Management strategies for maximizing carbon storage and tree species diversity in cocoa-growing landscapes
How do we manage the trade-offs between agricultural yields, biodiversity and ecosystem services? One option is to adopt high yield, intensive farming that allows land to be spared elsewhere for conservation (land sparing); another is to adopt low yield, extensive farming over a greater area that retains more biodiversity and protects ecosystem services (wildlife-friendly farming). We examine which is likely to be the best option to achieve high carbon storage and tree species richness in tropical cocoa-growing landscapes.
Bracken distribution in Great Britain: strategies for its control and the sustainable management of marginal land
Bracken is often perceived as a widespread and increasing land management problem. The pollen record of a wide range of sites in Great Britain suggests that the current abundance of bracken is less than or, at worst, equivalent to maximum historical levels. Recently gathered data also suggest that bracken cover is declining. Results of risk assessments of land use change, and experimental and modelling investigations into the effects of climate change are synthesized.
Woodland habitat structures are affected by both agricultural land management and abiotic conditions
CONTEXT: The identification of habitat structures with biologically meaningful links to habitat quality has enabled an increased understanding of wildlife distributions in fragmented landscapes. However, knowledge is lacking of where these structures occur in the landscape. OBJECTIVES: For a broad-scale agricultural landscape, we investigated how the occurrence and abundance of wildlife habitat structures is related to abiotic conditions and land management practices, and whether this differed between old growth and regrowth woodland.
Hydrological modelling of drained blanket peatland
Open ditch drainage is a commonly implemented land management practice in upland blanket peatlands, particularly in the UK, where policy decisions between the 1940s and 1970s led to widespread drainage of the uplands. The change in the hydrological regime associated with the drainage of blanket peat is poorly understood, yet has perceived importance for flooding, low flows and water quality. We propose a new simplified physics-based model that allows the associated hydrological processes and flow responses to be explored.
Multi‐Taxa Assessment of Biodiversity Change After Single and Recurrent Wildfires in a Brazilian Amazon Forest
In the last decades, due to human land management that uses fire as a tool, and due to abnormal droughts, many tropical forests have become more susceptible to recurrent wildfires with negative consequences for biodiversity. Yet, studies are usually focused on few taxa and rarely compare different fire frequencies. We examined if the effects of single and recurrent fires are consistent for leaf litter ants, dung beetles, birds (sampled with point‐counts PC and mist net‐MN), saplings, and trees.
Factors affecting farmland management in Poland in 1992-2012 in the institutional context
The aim of this article has been to identify and evaluate main factors which influence the agricultural land market in Poland. Statistical data from two institutions, namely the Agricultural Property Agency (APA) and the Central Statistical Office (CSO) as well as the author’s research have been used in the paper. The time horizon of the analysis covers the years 1992-2012. The lower limit was determined by the start of operation of the Agency of Agricultural Property of the State Treasury and the launching of a process of transformation in agriculture state.
Environmental perceptions and practices of livestock keepers on the Namaqualand Commons challenge conventional rangeland management
Assessment of soil organic carbon in semi-arid Sudan using GIS and the CENTURY model
Using the UNFCCC as a basis, and the objectives of estimating soil organic carbon (SOC) changes during the period 1900–2100, a spatially explicit database of climate, land cover and soil texture was compiled for a 262,000 km2 region in semi-arid Sudan. The area is characterized by low input cultivation of millet, sorghum and sesamé combined with livestock grazing. By integrating the database with the CENTURY ecosystem model, we were able to estimate historical, current and future pools of SOC as a function of land management and climate.

Litter production and decomposition in the forested areas of traditional homegardens: a case study from Barak Valley, Assam, northeast India
Homegardens are one of the oldest forms of managed land use systems characterised by high diversity and complexity of their species structure which in turn contribute to efficient nutrient cycling. Litterfall and decomposition are the two major processes that replenish the soil nutrient pools and endow sustainability to these agroforests. A study was carried out in the village Dargakona, Barak Valley, northeast India to understand the pattern of litter production and litter decomposition in the traditional homegardens.
