title: Land and Soil Health Assessment in the Western Amazon Sentinel Landscape

description: This dataset was moved to: https://doi.org/10.34725/DVN/2FTPZ5The LDSF was carried out at three-100 km2 sites within the Western Amazon Sentinel Landscape. Madre de Dios and Ucayali in Peru, and Pando in Bolivia. Field teams were trained by Norvin Sepulveda (CATIE, Nicaragua- Honduras SL) and Noel Ulloa in August 2014. Field surveys were completed in July 2015. The LDSF is a spatially stratified, randomized sampling design, developed to provide a biophysical baseline at landscape level and a monitoring and evaluation framework for assessing processes of land degradation and effectiveness of rehabilitation measures over time. Measured variables include: land cover, tree and shrub densities, tree biodiversity, erosion prevalence, infiltration capacity, along with an assessment of impact to habitat and occurrence of soil conservation structures. Soil samples were also collected (320 top (0-20 cm) and sub (20-50 cm) soil samples per site) and were processed in Managua. Processed samples were shipped to Nairobi and subjected to infrared spectroscopy and wet chemistry analysis. These combined data sets will be used to assess soil and ecosystem health for the landscape in more detail.

title: Mekong Village Level Baseline

description: This dataset was moved to: https://doi.org/10.34725/DVN/XXW0JGThis study consists of village level baseline data and other related materials generated as part of the ‘Sentinel Landscapes’ initiative. The village level baseline data was collected using four survey protocols designed by the International Forest Resources and Institutions (IFRI). The data collected is used to understand the relationship between communities, local governance and forests. Four IFRI protocols were used for this purpose: (i) Forest Form (ii) Settlement Form (iii) Association Form and (iv) Product Form. The instruments facilitate the collection of political and institutional data at communal level for those communities that use those forests. In China, a total of 35 villages were surveyed between November 2014 and January 2015 namely: MengLuo, ZhuShiHe, LanTianXiaZhai, DaHuangBa, SiJjiaCun, DingJiaZhai, YangJiaZhai, DaBa, MengYeBa, ChaHe, ManSa, DaZhai, LanTianShangZhai, DingJiaShangZhai, DingJiaXiaZhai, PaXiHe, ZhangJiaWan, JiuMiao, XinZhai, Xiaofang, Manda, Manfa, Mangajian, Mankong, Manlao, Manleidai, ManLeine, Manlongdong, Manluanga, Manna, Mansaojing, Mantang, Manyingdai, Manyingne, Manyuan In Thailand, a total of 15 villages were surveyed between November 2014 and January 2015 namely: Ban Hok, Ban Krueng Tai, Ban Kwak Nuea, Ban Lo, Ban Luang, Ban Muangchoom, Ban Nern Somboon, Ban San, Ban Sri Mongkol, Ban Srivilai, Ban Tha Chareon, Ban Thakham, Ban Tong, Ban Tonplong, Ban Yai Nuea In Laos, a total of 15 villages were surveyed between November 2014 and January 2015 namely: Sienglea, Phiahuanam, Phonsa At, Napa, Namet, Thamun, Pangthong, Huaylor, Nangoua, Mang, Namtouy, Yor, Lai Gnai, Muanghom, Nalai.

title: Replication Data for: Improving commercialization of Cola spp. in Cameroon – applying lessons from NTFPs in a context of domestication

description: This dataset was moved to: https://doi.org/10.34725/DVN/PBSKRSDevelopment organizations and research institutes worldwide have implemented numerous projects that target improved production, use and commercialization of Non-Timber Forest Products (NTFPs) and Agroforestry Tree Products (AFTPs) for livelihoods, markets and biodiversity purposes. These projects aim to contribute towards the Millennium Development Goals of eradicating poverty and hunger and promoting social equity and environmental sustainability. Given the current lack of impact studies, this review paper attempts to summarize the bottlenecks, potentials and impacts of improved NTFP commercialization, and apply the lessons learnt in a context of emerging domestication efforts on cola nut (Cola spp.) in Cameroon. Several limitations to increased cola commercialisation are listed. There are biological constraints, as well as those related to market organization. Projects aiming to improve NTFP/AFTP commercialization have the potential to improve farmers’ livelihoods and to contribute to the conservation of the natural resources. However, no consensus on the real impact could be deduced from evaluation studies, since some of these projects failed to deliver the expected benefits in terms of poverty alleviation, led to resource overexploitation and put pressure on traditional tenure systems. On the other hand, collective action at producer level was found to result in improved market information, increased product quality and quantity, reduced transaction costs, enhanced negotiating abilities and strengthened social bonds. Benefitting also traders, group sales comprised a win-win situation. Finally, this article looks at the position of women who are important NTFP/AFTP value chain actors and finds that improved commercialization can have both positive and negative effects on women’s livelihoods.

title: Replication data for: Reconciling Legal-Institutional and Behavioral Perspectives on Voter Turnout: Theory and Evidence from Pennsylvania, 1876-1948

description: Foundational studies in political science endeavored to explain the dynamics of voter turnout in America over time. Two theories, one focused on legal-institutional factors and the other on behavioral elements such as party mobilization strategies, were born from the need to account for temporal fluctuations in aggregate voter turnout. A comprehensive test of these competing theories has been hindered by the fact that reliable measures of the behavioral factors driving turnout have proven elusive. In this paper I develop and test an interactive theory of voter turnout that focuses on the impact of legal-institutional barriers to the franchise conditional on party organizational strength and mobilization efforts. To this end I employ data on the circulation of party-sponsored newspapers, coupled with information on the spread of voter registration requirements, to capture the effects of both behavioral and legal-institutional factors in Pennsylvania between 1876 and 1948. My results offer modest empirical support for an interactive theory of aggregate voter turnout. In isolation, however, the effects of behavioral factors are quite limited. On the other hand, legal-institutional variables exert a sizeable impact on voter turnout in the state. Contrary to other recent work on the subject, careful analysis of the Pennsylvania case therefore provides a great deal of evidence in favor of legal-institutional accounts of the changes in aggregate voter turnout that were witnessed at the beginning of the 20th century, while at the same time demonstrating that behavioral factors, such as the decline of the partisan press, served to enhance the del eterious effects of legal reforms on turnout.

title: Carbon neutral? No change in mineral soil carbon stock under oil palm plantations derived from forest or non-forest in Indonesia. Agric. Ecosyst. Environ. (2015). http://dx.doi.org/10.1015/j.agee.2015.06.0009

description: This dataset was moved to: https://doi.org/10.34725/DVN/BNFMONSustainability criteria for palm oil production guide new planting towards non-forest land cover on mineral soil, avoiding carbon debts caused by forest and peat conversion. Effects on soil carbon stock (soil Cstock) of land use change trajectories from forest and non-forest to oil palm on mineral soils include initial decline and subsequent recovery, however modeling efforts and life-cycle accounting are constrained by lack of comprehensive data sets; only few case studies underpin current debate. We analyzed soil Cstock (Mg ha-1), soil bulk density (BD, g cm-3) and soil organic carbon concentration (Corg, %) from 155 plots in 20 oil palm plantations across the major production areas of Indonesia, identifying trends during a production cycle on 6 plantations with sufficient spread in plot age. Plots were sampled in four management zones: weeded circle (WC), interrow (IR), frond stacks (FS), and harvest paths (HP); three depth intervals 0-5, 5-15 and 15-30 cm were sampled in each zone. Compared to the initial condition, increases in Corg (16.2%) and reduction in BD (8.9%) in the FS zone, was compensated by decrease in Corg (21.4%) and increase in BD (6.6%) in the HP zone, with intermediate results elsewhere. For a weighted average of the four management zones and after correction for equal mineral soil basis, the net temporal trend in soil Cstock in the top 30 cm of soil across all data was not significantly different from zero in both forest- and non-forest-derived oil palm plantations. Individual plantations experienced net decline, net increase or U-shaped trajectories. The 2% difference in mean soil Cstock in forest and non-forest derived oil palm plantations was statistically significant (p&lt;0.05). Unless soil management changes strongly from current practice, it is appropriate for C footprint calculations to assume soil Cstock neutrality on mineral soils used for oil palm cultivation.

title: Survival, growth and reproduction of the amphipod Hyalella azteca in 42-d water only treatments with and without the addition of bromide

description: Poor survival, growth and reproduction of the amphipod Hyalella azteca has been observed in exposures using reconstituted waters. Previous studies have reported success in H. azteca water-only exposures with the addition of relatively high concentrations of bromide (Br). This study evaluated the influence of lower environmentally representative concentrations of Br on the response of the amphipod H. azteca in 42-d water-only exposure conditions in various reconstituted waters. Improved performance of H. azteca was observed in reconstituted waters with &gt;0.02 mg Br/L. These tables and figures provide online supplemental information that will not be included in the journal article.

title: Total elemental composition of soils in Sub-Saharan Africa and relationship with soil forming factors

description: This dataset was moved to: https://doi.org/10.34725/DVN/4VOYZWA thorough understanding of the variation in total soil element concentrations is important especially in the Sub-Saharan Africa (SSA) soil contexts for agricultural and environmental management at large scale. Fingerprinting of soil elemental composition may form a useful basis for evaluating soils in a way that relates to soil-forming factors and inherent soil functional properties. The objectives of this paper are to quantify the proportion of variability in total elemental composition by total X-ray fluorescence (TXRF) method of 1074 soil samples from the Africa Soil Information Service (AfSIS) Project baseline and to determine the relationships with soil forming factors. The samples were from 34 sentinel sites measuring 10 × 10 km, randomized within major climate zones in SSA. Within each sentinel site there were sixteen spatially stratified 1 km2 clusters, within which there were ten 100 m2 plots. The within and between site patterns of variation in total element composition of 17 elements; Al, P, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, Sr, Y, Ta, and Pb, were explored. Total element concentration values were within the range reported globally for soil Cr, Mn, Zn, Ni, V, Sr, and Y and higher than reported range for Al, Cu, Ta, Pb, and Ga. There were significant variations (P &lt; 0.05) in total element composition within and between the sites for all the elements analyzed with the greatest proportion of total variance and number of significant variance components occurring at the site (55–88%) followed by the cluster nested within site (10–40%) levels. The explorations of the relationships between element composition data and site factors using RandomForest regression demonstrated that soil-forming factors have important influence on total elemental composition in the soil. The fact that the soil-forming factors are related to the concentration of naturally occurring elements in the soil gives rise to the notion that they might be predicted from the soils' element composition. Results implied that &gt;70% of variation in soil element composition patterns can be predicted using information in existing databases or readily observable features. Successful use of TXRF technique would open up possibilities for using total soil elemental composition fingerprints as a useful basis for characterizing soils in a way that relates to soil-forming factors and inherent soil functional properties.

title: Mid-infrared and total X-ray fluorescence spectroscopy complementarity for assessment of soil properties

description: This dataset was moved to: https://doi.org/10.34725/DVN/N0UGWLDiffuse reflectance Fourier transformed mid-infrared (DRIFT-MIR) spectroscopy can predict many soil properties but extractable nutrients are often predicted poorly. This paper tested the combined DRIFT-MIR and total X-ray fluorescence (TXRF) spectroscopy analysis for prediction of soil properties related to soil fertility. A total of 700 soil samples from 44 stratified randomly located 100-km2 sentinel sites distributed across Sub-Saharan Africa (SSA) were analysed for physicochemical composition using conventional reference methods, and compared with MIR and TXRF spectra using Random Forests (RF) regression algorithm and an internal out-of-bag (OOB) validation. Mid-infrared spectra resulted in good prediction models (R2 &gt; 0.80) for organic C and total N, Mehlich-3 Ca and Al, and pH. Moderately predicted (R2 &gt; 0.60) were extractable Mg, P sorption index, sand, silt, and clay. Models were less satisfactory (R2 &lt; 0.60) for Mehlich-3 extractable K, Mn, Fe, Cu, B, Zn, P, S, and Na, exchangeable acidity and electrical conductivity (Ecd). Inclusion of total element concentration data from TXRF analysis in the MIR RF models significantly reduced root mean square error of prediction by 70% for Ecd, 66% for Mehlich-3 Na, 61% for Mehlich-3 S, and 50% for Mehlich-3 B due to detection by TXRF of some saline soils that were not well predicted by MIR. Overall, both methods predicted soil properties that relate to nutrient buffering capacity, including some exchangeable bases, pH, P sorption capacity, clay content, and organic matter content, and fingerprint basic soil mineralogy. Thus, further research should test whether MIR and TXRF fingerprinting could better predict soil nutrient supply capacity, as determined by crop nutrient uptake potential, than conventional soil P, K and micronutrient tests.

title: Aquatic invertebrates and vegetation and water-quality of Big Stone National Wildlife Refuge, Minnesota: 2013-2014

description: During 2013 and 2014 aquatic invertebrates were collected and vegetation was inventoried from sample locations distributed throughout Pool 10 and West Pool of Big Stone National Wildlife Refuge. Invertebrate sampling was conducted using aquatic activity traps and by collecting organisms from submersed vegetation. Vegetation was inventoried through a combination of visual observation and collection using the rake method. In conjunction with the invertebrate and vegetation sampling, water depth was recorded and the following water-quality parameters were collected using a multi-parameter Sonde: dissolved oxygen, oxidation-reduction potential, pH, specific conductance, water temperature, and turbidity. For the aquatic invertebrates, the database includes taxonomic identification, number, and mass for each sample (activity trap). Vegetation variables for each subsampling area include taxonomic identification, an overall and species-specific visual density rating, and a density rating for the rake samples. Presence of non-common species also is included. Data were collected to provide baselines and comparisons to inform refuge management decisions.

title: Replication data for: Preparing the ground for better landscape governance: gendered realities in southern Sulawesi

description: This dataset was moved to: https://doi.org/10.34725/DVN/A07QFAIn recognition of the importance of effective and equitable governance at the landscape scale in enhancing human and environmental well-being, we use a recently developed framework for assessing men’s and women’s involvement in local governance. These results set the stage for an ongoing examination of the success of the AgFor project in southern Sulawesi in achieving this goal. Our findings establish a baseline on gender and governance in five communities with landscapes that include forestry, agroforestry, and agriculture: Bonto Tappalang and Tana Toa in South Sulawesi, and Tawanga, Ladongi, and Wonua Hua in Southeast Sulawesi. These indicators, which we complement with ethnographic insights, fall into two categories: (1) level of public involvement and (2) skills relevant for political action, each of which is assessed for both women and men. Our findings reflect what we believe to be a comparatively equitable gender situation in Sulawesi, with hopeful prospects for enhancing women’s (and men’s) public involvement in governance. We conclude with some practical and ethnographically informed suggestions for enhancing collaboration with women and men in these (and similar) communities.

title: Replication data for: Gender roles and knowledge in plant species selection and domestication: case study in South and Southeast Sulawesi

description: This dataset was moved to: https://doi.org/10.34725/DVN/4UCTTYWomen and men have different sets of knowledge, experiences, and strategies in addressing aspects of plant domestication such as plant propagation, management, utilisation and marketing. Identification of gender roles and knowledge related to tree domestication is important in planning for tree-basedlivelihood enhancement and sustainable environmental management, however, such identification has not yet beensufficiently researched to date. This study investigated gendered selection of economically priority species and their domestication in South and Southeast Sulawesi. From the focus group discussion, both men and women give priority to tree species with high economic value; the management of those species is a stronger priority for men but is also expressed by women. However, specifically for their livelihoods, women are keen to domesticate vegetables and other annual crops that contribute directly to household food security and nutrition.

title: Replication Data for: Local Perception on Land Use Systems and Biodiversity in a Rubber Plantation of North Sumatera.

description: This dataset was moved to: https://doi.org/10.34725/DVN/29788Forest area in North Sumatera has declined since many years ago and have changed to more intensive land use systems, e.g. oil palm plantation, rubber monoculture plantation and smallholder. The study of local perception on land use systems and biodiversity was conducted in six villages in Simalungun district, Asahan district, and Serdang Berdagai district, North Sumatera province, to understand local preferences for land-use systems, local perceptions on land-use functions, and values on biodiversity, using Multidisciplinary Landscape Analysis (MLA) approach. The study showed that smallholder rubber and oil palm were the main sources of livelihoods in almost every village, since the two land use systems were important as cash income source. All participants perceived that rubber agroforest was the most important land use, as it could provide sources of income, food and environment values. Peoples understanding on biodiversity was closely associated with livelihood patterns and social life, as biodiversity contributed to their daily needs, and related to specific knowledge. All rubber plots under mixed and monoculture systems were perceived as good value in preventing erosion, while oil palm plots were of relatively low value. Interestingly, people also understood that forest had the highest function as an erosion control as these area are prone to soil erosion due to topography. Local people classified flora and fauna diversity based on their functions, such as food, source of income, fuelwood, construction, medicine, fodder, handycraft and tools, and erosion control. They noticed different biodiversity occured in different land-use types. Rubber agroforests provide all needs, e.g. goods and services, for local communities
