title: Replication Data for: Genetic variation and clines in growth and survival of Prosopis africana from Burkina Faso and Niger: comparing results and conclusions from a nursery test and a long-term field test in Niger

description: This dataset was moved to: https://doi.org/10.34725/DVN/ANGAPDRural communities in West Africa value Prosopis africana for its wood and other essential products and environmental services. The climate is becoming hotter and drier with more variable rainfall, so it is important to identify provenances that are better adapted to a hotter, drier climate. Some tree improvement research programs use nursery tests to identify better adapted provenances, but are conclusions comparable to those from field tests? We analyzed data (height, root dry weight, shoot dry weight, root/shoot ratio, survival) from a provenance/progeny nursery test of P. africana at 8 months, and compared the results with a field test at 11 and 13 years. The tests included 275 families from 28 provenances in the Sahelian and Sudanian ecozones of Burkina Faso and Niger, and were established at one relatively dry site in Niger. The proportion of total variance due to provenances and families within provenances was greatest for root/shoot ratio, and root/shoot ratio had the highest heritability of growth variables in the nursery. Provenances with smaller seedlings and larger root/shoot ratios in the nursery had better growth and survival in the field, and were from drier locations. Mean annual rainfall of provenances was the best predictor of provenance growth and survival in the field, followed by provenance height and root/shoot ratio in the nursery. We recommend that tree improvement research programs in the Sahelian and Sudanian ecozones of West Africa identify P. africana provenances that are from drier locations and have smaller seedlings and larger root/shoot ratios in the nursery for planting in agroforestry projects in rural communities.

title: Replication data for: Aboveground carbon stocks in oil palm plantations and the threshold for carbon-neutral vegetation conversion on mineral soils

description: This dataset was moved to: https://doi.org/10.34725/DVN/BXRB2RThe carbon (C) footprint of palm-oil production is needed to judge emissions from potential biofuel use. Relevance includes wider sustainable palm oil debates. Within life cycle analysis, aboveground C debt is incurred if the vegetation replaced had a higher C stock than oil palm plantations. Our study included 25 plantations across Indonesia, in a stratified study design representing the range of conditions in which oil palm is grown. From allometric equations for palm biomass and observed growth rates, we estimated the time-averaged aboveground C stock for 25-year rotations and 95%-confidence intervals to be 42.07 (42.04-42.10) Mg C ha-1 for plantations managed by company on mineral soil, 40.03 (39.75-40.30) Mg C ha-1 for plantations managed by company on peat, and 37.76 (37.42-38.09) Mg C ha-1 for smallholder oil palm on mineral soils. Oil palm can be established C debt-free on mineral soils with aboveground C stocks below these values; neutrality of mineral soil C pools was documented in a parallel study. Acknowledging variation in shoot:root ratios, the types of vegetation that can be converted debt-free to oil palm include grasslands and shrub, but not monocultural rubber plantations, rubber agroforest, and similar secondary or logged-over forests of higher C stock.

title: Replication data for: The Balance of Power in Household Decision-Making: Encouraging News on Gender in Southern Sulawesi

description: This dataset was moved to: https://doi.org/10.34725/DVN/HND9YCAnalyses of intra-household decision-making in Sulawesi are linked to gender issues shown to affect involvement in landscape management. These include agriculture, food, money, life chances, and attitudes toward domestic violence. The picture portrayed is encouraging, showing the social sophistication of a group often marginalized: This group shows considerable female involvement in decision-making and strongly democratic elements. We identify three issues that need greater attention—for equitable landscape management to result: women’s spheres of decision-making must be ascertained and taken into account, men’s involvement in care needs to expand, and women’s agency requires enhancement and external support.

title: Replication data for: Intercropping Teak (Tectona grandis) and Maize (Zea mays): Bioeconomic Trade-off Analysis of Agroforestry Management Practices in Gunungkidul, West Java

description: This dataset was moved to: https://doi.org/10.34725/DVN/PG6BZIProducing high quality wood meeting export standards requires intensive tree management. Using a tree-crop interactions model (WaNuLCAS) we analyzed tree management practices in intercropped teak and maize compared to teak and maize monocultures. Tradeoff analysis in intercropped teak and maize was designed in a three-treatment factorial: initial teak density (1600 trees ha-1 (2.5m × 2.5m), 1111 trees ha-1 (3m × 3m) and 625 trees ha-1 (4m × 4m)), thinning intensity (light (25%), moderate (50%) and heavy (75%) of tree density), and pruning intensity (40% and 60% of crown biomass). Cumulative maize yield in the first 5 years of teak growth increased 10% – 38% when tree density was reduced. All simulated intercropping practices produced a higher wood volume then a monoculture, as trees benefit from crop fertilization. Maximum wood volume (m ha-1) was obtained at initial tree density of 625 trees ha-1, 25% of which was thinned in year 5 and another 25% in year 15 with 40% of the crown pruned in years 4, 10 and 15. However, greater stem diameter as can be obtained with further thinning is rewarded with higher market price per volume of wood. Profitability analysis taking into account the cost of labour (for maize production, thinning and pruning) and its effect on additional timber revenue showed that the highest Net Present Value and return to labour was provided by the system with 50% thinning in year 5. Economic optimization was not sensitive to variations around the default price assumptions.

title: Replication Data for: Can gender appreciation of trees enhance landscape multifunctionality? A case of smallholder farming systems on Mount Elgon

description: This dataset was moved to: https://doi.org/10.34725/DVN/SCKGMVTrees provide livelihood support functions and environmental services that contribute to the multifunctionality of landscapes. The presence or absence of trees is influenced by the interactions between ecological, social-economic and cultural elements. The role of gender in land use perceptions and changes involving trees have received little attention. In Africa, gender differentiated access, use and decision-making related to trees are common features. Divergent control and access to resources by men and women are likely to influence their perceptions and preferences for trees in the landscape. This paper discusses the results of an assessment of men's and women's appreciation of trees in Kapchorwa District, on the slopes of Mount Elgon in Uganda. While men and women were found to have differences in their access to tree products, decision-making powers and agroforestry practices, their land use preferences and perceptions of environmental services were similar. The paper provides recommendations on community forest management, agroforestry programmes and conservation agreements.

title: Replication Data for: Participatory forest management in Burkina Faso: members’ perception of performance

description: This dataset was moved to: https://doi.org/10.34725/DVN/VFGISYThis study examines variations in the performance of participatory forest management programs among four forest management groups (FMGs) in southern Burkina Faso, and assesses the factors that influence their members’ perceptions of performance through a household survey of 216 members. Variations in performance scores among the FMGs were analyzed through multivariate analysis of variance while multinomial regression analysis was used to identify factors that influence their perception of the performance. The results reveal significant differences in performance scores among FMGs. Members of some FMGs perceived that the participatory forest management program enabled them to get benefits from the sale of fuelwood while performance scores in the forest conservation and decision-making processes is generally poor. The score for economic performance of FMGs in turn was related to better access to roads and markets. Group size tended to enhance economic performance via its strong influence on annual fuelwood harvest, while the resource base appeared to be inconsequential. Members of the forest management groups perceived that large group size and group heterogeneity, particularly in terms of ethnicity, as well as knowledge and awareness of problems related to the forest environment have no influence on the performance of their respective groups. For rural communities to have a favorable disposition toward sustainable forest management, differences in member understanding of collective actions and their impact before and during the implementation of participatory forest management programs should be considered.

title: Replication data for: Plant elemental composition and portable X-ray fluorescence (pXRF) spectroscopy: quantification under different analytical parameters

description: This dataset was moved to: https://doi.org/10.34725/DVN/WGWE8SEmergence of portable X-ray fluorescence (pXRF) systems presents new opportunities for rapid, low-cost plant analysis, both as a lab system and in situ system. Numerous studies have extolled the virtues of using pXRF for a wide range of plant applications, however, formany such applications, there is need for further assessmentwith regards to analytical parameters for plant analysis. While pXRF is a potential powerful research tool for elemental composition analysis, its successful use in plant analysis is made more likely by having an understanding of X-ray physics, calibration process, and ability to test a variety of homogenous and well-characterized materials for developing a matrix-specific calibration. Because potential pXRF users may often underestimate the complexity of proper analysis, this study aims at providing a technical background for plant analysis using pXRF. The focus is on elemental quantification under different analytical parameters and different methods of sample presentation: direct surface contact under vacuum, placement in a sample cup with prolene as a seal, and without the aid of a vacuum. Direct analysis on the surface of a pXRF provided highest sensitivity and accuracy (R2&gt;0.90) for light elements (Mg to P). Sulfur, K, and Ca can be reliably measured without the aid of a vacuum (R2&gt;0.99, 0.97, and 0.93 respectively), although lower detection limits may be compromised. pXRF instruments provide plant data of sufficient accuracy for many applications and will reduce the overall time and budget compared with the use of conventional techniques. Sensitivity and accuracy are dependent on the instrument’s settings, make, and model.

title: Replication Data for: Improved seed germination of four savanna-woodland species: effects of fire-related cues and prolonged soaking in sulphuric acid

description: This dataset was moved to: https://doi.org/10.34725/DVN/0UTGWAA study was carried out to investigate the effects of fire related cues (heat and smoke) and sulphuric acid treatments on the germination of four woody savanna species, namely, Terminalia avicennioides, Piliostigma thonningii, Piliostigma reticulatum and Prosopis africana. The heat treatment consisted of putting seeds in a preheated oven at 100,150 and 200 °C for 2.5 min. Seeds were then soaked in four concentrations of smoke solution (0 (tap water), 25, 50 and 100% smoke solutions). Parallel to smoke and heat treatment, seeds of the four species were each soaked in concentrated sulphuric acid for 2 hours and also according to the conventional soaking time of each species. Under experimental conditions, heat and smoke did not stimulate seed germination. For P. thonningii and P. africana, soaking seeds for 2 hours in sulphuric acid significantly increased germination capacity compared with conventional soaking time of 5 min. Longer soaking time reduced mean germination time. Results of this study will be useful in the establishment of these species.

title: Replication Data for: Effect of Inoculating Seeds with Bradyrhizobium japonicum on the Agronomic Performance of Five Varieties of Soybean (Glycine max) in Côte d’Ivoire

description: This dataset was moved to: https://doi.org/10.34725/DVN/QWZMUIRecent studies in the Nawa region of Cote d’Ivoire have indicated an acute malnutrition rate of 11.3% among cocoa producers. One of recommended actions from the studies was to diversify agriculture with nutrients rich crops. Introduction of soybean (Glycine max) cropping system could go a long way to ensure food and nutritional security in the region. The current study was conducted in two sites (Logboayo and Soubré) in the south-west of Cote d’Ivoire, to evaluate the effect of IRAT-FA3 Bradyrhizobium japonicum strain inoculum on the agronomic performance of five varieties of soybean named Doko, Canarana, V3_2013, V6_2013 and IT_235. The experimental design was randomized complete block with a split plot with inoculation as the main factor and variety of soybean as subplot treatment replicated three times. Data were collected on some yield parameters and the grain yield. Results of yield showed a highly significant effect (P&lt;0.0001) of the site and a significant effect (P=0.0316) of the variety x treatment interaction. Highest yield was recorded at Logboayo with 1838 kg ha-1 compared to 1220 kg ha-1 for Soubre. The variety V6_2013 with a yield of 1931 kg ha-1 and good vegetative development could be recommended as elite variety for the farmers in the Nawa region.

title: Replication Data for: Rôle des feux de savane sur les caractéristiques biogéochimiques des sols en zone soudanienne du Burkina Faso

description: This dataset was moved to: https://doi.org/10.34725/DVN/WPB4MVLes feux de brousse dont les effets dépendent aussi bien de leurs intensités ainsi que de leur saison d’occurrence, sont considérés comme une perturbation écologique majeure des écosystèmes savanicoles. L’objectif général de cette étude est de générer des connaissances sur l’effet de la quantité du combustible et de la saison du feu sur le comportement du feu et les propriétés chimiques et biologiques du sol afin d’aider à la gestion des écosystèmes savanicoles. Les travaux de recherches ont été menés dans un dispositif expérimental couvrant 11,16 ha et installé dans la savane sud-soudanienne boisée de la forêt classée de Dindéresso (11° 13’ 59, 88’’ latitude nord and 4° 25’ 59, 59’’ longitude ouest). Sur la base de la quantité du combustible, trois traitements (Combustible réduit correspondant à la parcelle dont la quantité de combustible a été réduite de moitié; Combustible Normal pour la parcelle dont le combustible initial a été coupé et réparti de façon uniforme et le Combustible augmenté correspondant à la parcelle où la seconde moitié soustraite en CR a été rajoutée au combustible initial) ont été considérés en plus du témoin dans les deux régimes de feu. Les résultats n’ont montré aucune différence significative dans la vitesse de progression et dans l’intensité du feu. Cependant, un plus grand enrichissement en éléments nutritifs des couches superficielles a été observé. Le feu tardif a eu un effet plus néfaste sur les propriétés chimiques du sol que le feu précoce. L’effet immédiat du feu sur la macrofaune a été la réduction considérable du nombre d’individus. Toutefois, la quantité du combustible n’a affecté ni la composition ni l’abondance de la macrofaune. Les enseignements tirés de l’étude sur le comportement du feu ainsi que les résultats sur l’effet du feu sur les paramètres chimiques et biologiques du sol peuvent donc aider dans la gestion des formations boisées en zone soudanienne mais des investigations doivent cependant se poursuivre pour affiner les connaissances à l’échelle du paysage.

title: Land and Soil Health Assessment in the Central Africa Humid Tropics Transect (CAFHUT) Sentinel Landscape

description: This dataset was moved to: https://doi.org/10.34725/DVN/V8M94DThe LDSF was carried out at two-100 km2 sites within the Central Africa Humid Tropics Transect (CAFHUT) Sentinel Landscape: Etiolomo and Ayos in Cameroon. Field teams were trained by Bertin Takoutsing and field surveys were completed in April 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 Burkina Faso. 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: USGS National Assessment of Oil and Gas Project - Cherokee Platform Province Assessment Units

description: The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic elements that define the Assessment Unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are Assessment Units that border the Federal-State water boundary. In these cases, the Federal-State water boundary forms part of the Assessment Unit boundary.

title: Replication data for: The Electoral Determinants of State Welfare Effort in the U.S. South, 1960-2008

description: This article examines the impact of electoral politics on state welfare policy in the post-civil rights era South. In contrast to an emerging consensus concluding that southern African Americans materially benefited from rejoining the electorate, this study suggests that higher black registration rates actually reduced states’ poverty relief efforts. In the immediate post-VRA years, when Democrats controlled state government, the significant negative relationship between the size of the black electorate and state welfare generosity was moderated to some extent by high levels of partisan competition. In such cases Democrats ostensibly chose a “core” targeting strategy of pursuing lower-income votes and had the institutional wherewithal to purchase these votes with policy concessions. Overall, however, the liberal “Downsian” policy response to African American mobilization was dominated by an anti-redistributive response. In the South, welfare policies were relatively conservative vis-à-vis the other states during Jim Crow and became even more so in response to black voting.
