However, the precise relationships between soil properties and microbial diversity are poorly known. Here, we study the effect of agricultural management on soil microbial diversity and C turnover in tropical grassland of north-eastern Laos. Three years after native grassland conversion into agricultural land, we compared soils from five land use management systems: one till versus two no-till rotational cropping systems, one no-till improved pasture and the natural grassland. Soils were incubated in microcosms during 64 days at optimum temperature and humidity. Bacterial and fungal diversity were evaluated by metagenomic 454-pyrosequencing of 16S and 18SrRNA genes, respectively. Changes in soil respiration patterns were evaluated by monitoring 12C- and 13C-CO2 release after soil amendment with 13C-labelled wheat residues. Results show that residue mineralization increased with bacterial richness and diversity in the tilled treatment 7 days after soil amendment. Native soil organic C mineralization and priming effect increased with fungal richness and diversity in improved pasture and natural grassland. No-till cropping systems represented intermediate situations between tillage and pasture systems. Our findings evidence the potential of controlling soil microbial diversity by agricultural practices to improve soil biological properties. We suggest the promotion of no-till systems as a fair compromise between the need for agriculture intensification and soil ecological processes preservation.", "keywords": ["P33 - Chimie et physique du sol", "cycle du carbone", "Microbial diversity", "Conservation agriculture", "F08 - Syst\u00e8mes et modes de culture", "agro\u00e9cologie", "http://aims.fao.org/aos/agrovoc/c_7172", "[SDV.SA.SDS]Life Sciences [q-bio]/Agricultural sciences/Soil study", "630", "Tillage", "biodiversit\u00e9", "labour", "Acid savannah", "http://aims.fao.org/aos/agrovoc/c_12076", "biologie du sol", "http://aims.fao.org/aos/agrovoc/c_33990", "http://aims.fao.org/aos/agrovoc/c_2018", "sol acide", "Priming effect", "savane", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "http://aims.fao.org/aos/agrovoc/c_6154", "pratique culturale", "http://aims.fao.org/aos/agrovoc/c_8511", "F07 - Fa\u00e7ons culturales", "2.

Historical changes in land cover and land use were analyzed using a chronological series of remote sensing data. Impacts of landscape change on local livelihoods were investigated in seven villages through interviews with various stakeholders. The study reveals that the complex mosaics of agriculture and forest patches observed in the study area have long constituted key assets for the resilience of local livelihood systems in the face of environmental and socio-economic risks. However, over the past 20 years, a process of segregating agricultural and forest spaces has increased the vulnerability of local land users. This process is a direct outcome of policies aimed at increasing national forest cover, eradicating shifting cultivation and fostering the emergence of more intensive and commercial agricultural practices. We argue that agriculture-forest segregation should be buffered in such a way that a diversity of livelihood opportunities and economic development pathways can be maintained.", "keywords": ["http://aims.fao.org/aos/agrovoc/c_195", "550", "F08 - Syst\u00e8mes et modes de culture", "t\u00e9l\u00e9d\u00e9tection", "0211 other engineering and technologies", "02 engineering and technology", "2739 Public Health", "910", "630", "couverture v\u00e9g\u00e9tale", "conservation des for\u00eats", "http://aims.fao.org/aos/agrovoc/c_3062", "for\u00eat", "K01 - Foresterie - Consid\u00e9rations g\u00e9n\u00e9rales", "11.

This perspective has had wide\uffe2\uff80\uff90ranging impacts on rural development policy which, in the uplands, has long favoured forest conservation over agriculture. Integrating soil erosion and water sediment data with local perceptions of land degradation in an upland village of northern Laos, this study tests the validity of the official environmental discourse. Biophysical measurements made in a small agricultural catchment indicate a significant correlation between the spatial extent of cultivation and soil erosion rates. However, sediment yields recorded at the outlet of the catchment highlight relatively low levels of off\uffe2\uff80\uff90site sediment exportation. Furthermore, farmers' perceptions suggest that local land degradation issues and crop yield declines could be less related to soil erosion than to agricultural land shortage, increased weed competition, and fertility losses resulting from the intensification of shifting cultivation. The study concludes that a better understanding and management of land degradation issues can be achieved by developing more inclusive and scientifically\uffe2\uff80\uff90informed approaches to environmental perceptions and narratives.</p>", "keywords": ["http://aims.fao.org/aos/agrovoc/c_24420", "http://aims.fao.org/aos/agrovoc/c_7170", "SOL CULTIVE", "F08 - Syst\u00e8mes et modes de culture", "culture itin\u00e9rante", "\u00e9rosion", "SEDIMENT", "POLITIQUE AGRICOLE", "SYSTEME DE REPRESENTATIONS", "http://aims.fao.org/aos/agrovoc/c_12076", "conservation des for\u00eats", "http://aims.fao.org/aos/agrovoc/c_3062", "for\u00eat", "http://aims.fao.org/aos/agrovoc/c_1374158672853", "DEGRADATION DU SOL", "http://aims.fao.org/aos/agrovoc/c_7165", "http://aims.fao.org/aos/agrovoc/c_2651", "intensification", "http://aims.fao.org/aos/agrovoc/c_34823", "http://aims.fao.org/aos/agrovoc/c_7168", "2.
