title: Vegetation Line Point Intercept Data, Owens Valley, CA USA 1984-2013

description: Each year, the Inyo County Water Department monitors vegetation conditions on the floor of the Owens Valley. The primary goal of this monitoring, according to the technical appendix to the Long-Term Water Agreement (Green Book) are to detect any significant decreases and changes in Owens Valley vegetation from conditions documented in 1984 to 1987. Vegetation live cover and species composition documented during the 1984-87 mapping effort were adopted as the baseline for comparison with each annual reinventory according to the Agreement. The reference measurements collected within individual areas mapped with similar vegetation (parcels) are referred to as baseline. The Green Book details certain decreases and changes in vegetation community types that must be avoided under the Agreement. Baseline vegetation communities in which evapotranspiration exceeds precipitation were classified as groundwater-dependent communities and are referred to as Types B, C, and D. These phreatophytic communities are dependent on shallow groundwater to maintain plant populations, as precipitation alone is inadequate to meet the water demand of these species. For these parcels, according to the Green Book, the goal is to manage groundwater pumping and surface water management practices so as to avoid causing significant decreases in live vegetation cover and to prevent a significant amount of vegetation from changing to a vegetation type that precedes it alphabetically (for example, Type C grass dominated meadow changing to type B shrub-dominated meadow). The goal is to manage the effect of pumping on the depth to groundwater to maintain baseline plant communities. A large proportion of groundwater-dependent parcels were mapped during baseline as Type C alkali meadows (61%), and the Agreement seeks to prevent these meadows from changing to shrub-dominated communities (Type B), a state change that is associated with increased depth to groundwater. Alkali meadows are of special concern because small increases in depth to groundwater can decouple the groundwater from the root zone of grass species.. Alkali meadow comprises 0.1% of the vegetation community types in California and 80% of alkali meadow communities in California are located within Owens Valley. Local management of water resources will be influential in determining the likelihood these ecosystems persist in California.

title: Replication data for: Effects of transformation processes on plant species richness and diversity in homegardens of the Nuba Mountains, Sudan

description: This dataset was moved to: https://doi.org/10.34725/DVN/26620Traditional homegardens (HGs) are considered to harbor high levels of plant diversity and have been therefore characterized as sustainable agro-ecosystems suitable for on-farm (incl. circa situm) conservation of plant genetic resources. While the functional structure of traditional HGs is poorly understood specifically for semi-arid and arid regions, their plant species richness and diversity is increasingly threatened by recent and fast evolving agricultural transformation processes. This has been particularly claimed for traditional jubraka HG systems of Sudan. Therefore, sixty-one HGs in four villages of the Nuba Mountains, South-Kordofan Province, Sudan, were randomly selected, geographically recorded and plant richness and abundance determined and plant diversity parameters ca lculated. In addition, socio-economic household data were assessed by interviews and soil samples taken to allow a comprehensive analysis of putative factors affecting HG plant diversity across different villages, levels of commercialization and plant species composition based clusters. A total of 110 species from 35 plant families were grown in the HGs along with 71 ornamentals. Perennial species accounted for 57 % including 12 indigenous fruit tree (IFT) species and six exotic fruit tree species. Mean species richness of useful plant species (excluding ornamentals) per HG was 23 (range 6â46). On average, 41 % of the 23 species per HG were of exotic origin, however, with a large range (21â83 %) among locations. Mean diversity and evenness indices were 1.46 (range 0.49â2.42) and 0.48 (0.15â0.87), respectively. The level of commercialization of HGs only marginally affected species diversity measures although the species richness was significantly higher for commercial than subsistence HGs. Species richness was higher on lower (6.6â7.2) pH soils. IFT richness was highly variable, but non-significantly different across the four locations. Plant species richness and diversity was high in comparison with other HG systems in semi-arid regions. Cluster analysis was found to be a valuable tool to classify HGs and to extract homogeneous HG types with low, intermediate and high richness and diversity. In addition, the share of exotic and ornamental species in HGs indicated a trend towards the loss of traditional farming practices, particularly in areas with good market access. The data did not indicate the hypothesized loss of inter-specific diversity due to commercialization and species richness was numerically even higher for market-oriented HGs compared to subsistence ones.

title: Western Kenya Integrated Ecosystem Management Project (WKIEMP) Ex Post Household Survey

description: This dataset was moved to: https://doi.org/10.34725/DVN/26664This study assessed the economic impact of the WKIEMP project on households in the Nyando and Yala river basins of Western Kenya. The survey included 362 households which together formed three groups – those formally involved in WKIEMP, those informally involved in WKIEMP and those not involved in WKIEMP. The data captured included variables on household characteristics and details of adoption behaviour of the interventions offered by the project. Further analyses in the paper modelled the adoption into impacts using a 20 year time horizon. From that model, benefit cost ratios, internal rates of return and net present values were calculated. These showed that there was a positive impact of the project before adding in additional carbon benefits. The analysis then contributed to an overall assessment of the project by the World Bank.

title: Energy demand survey in rural commercial centers of Western Kenya

description: This dataset was moved to: https://doi.org/10.34725/DVN/26665Due to increases in demand for fossil fuels and in the price of fuels, availability of energy to those of limited resources has declined. Access to sustainable energy is increasingly recognised as both a mechanism and a requirement for development. Thus, increasingly the role of energy, including bioenergy, in development and poverty reduction process is being considered. This study investigates demand for the proposed pyrolysis unit to generate bioenergy in developing countries at a local level. The survey was conducted across fifty six commercial centres in Western Kenya. The key findings include; issues continue to persist in relation to current fuel supply chains, the lack of availability of energy in small quantities acts as a barrier to the uptake and use of energy and development of the biofuels sector represents potential to increase incomes for transporters whilst strengthening rural market linkages.

title: Climate change perceptions and adaptations of rural households in Western Kenya

description: This dataset was moved to: https://doi.org/10.34725/DVN/26666The ICRAF contribution was to collect and analyse data from Kenya as part of a four country study on climate change perceptions and responses by rural communities and farmers. The formal survey was done in Bondo and Bungoma districts. The study found that farmers were undertake a range of different ex ante and ex post measures in response to various drivers and incentives. SLM type of investments were made to varying degrees but often not in direct response to climate change or variability. Nonetheless, it was generally found that yield variability is reduced when SLM investments were made.

title: Impact of fodder shrubs in East Africa

description: This dataset was moved to: https://doi.org/10.34725/DVN/26691The objective of this study is twofold, to demonstrate (1) the effects of fodder shrubs on milk production and their value at the household and regional level and (2) the contribution of research by the World Agroforestry Centre toward strengthening the impact of fodder shrubs. The study is a synthesis of previous studies related to dissemination, adoption and impact combined with two new analyses, one quantitatively measuring the impact of the shrubs through econometric analysis and the other a qualitative analysis to better understand constraints on adoption and gender issues related to participation and control of benefits from fodder shrubs. Among the study findings are that fodder shrubs have been widely adopted in East Africa, by an estimated 205,000 smallholder dairy farmers by 2005. Women were active in planting shrubs, as monitoring found almost half of planters to be women. Several studies have confirmed that shrubs do have an impact on milk production. While feeding trials have found that 1 kilogram of calliandra increases milk production by 0.6–0.8 kilograms, a new survey of f armers’ perceptions in Kenya found the effect to be about half as large after controlling for the effects of breeds, season and other feeds. Whether the effect is the lower or higher estimate, the overall impact of the shrubs in terms of additional net income from milk is high, at US$19.7 million to $29.6 million in Kenya alone over the past 15 years.

title: Testing Amazon Transitional Forest Leaf Flammability: Combustion Experiment Flammability Metrics (2013)

description: Intensifying land use practices and global climate change are leading to increased forest fragmentation and more severe droughts in the southeastern transitional forests of the Brazilian Amazon. The combination of land use and droughts has increased fire frequency, intensity, and extent in the region. Various plant traits can either limit or promote flammability, as demonstrated in many seasonally dry environments (e.g. Mediterranean shrublands), which are home to species that are adapted to frequent fire. However, little research has been done to associate flammability with the leaf traits of humid tropical forest species that are experiencing fire with greater frequency and severity than historically recorded. In this study, the leaf traits and consequent burning characteristics of seventeen species abundant in a transitional forest plot in Mato Grosso, Brazil were analyzed through controlled combustion experiments and trait measurements. Principal components analysis and linear regression were employed to compare leaf traits and their ability to predict flammability. The results reported herein show that these species demonstrate variability in flammability. Individual leaf surface area and leaf volume were found to be the most significant predictors of flammability among these species. The most flammable species were those with thin, lightweight leaves that become arranged in loosely packed, highly aerated fuelbeds and would be able to drive rapidly moving, high intensity fire across the forest floor, consuming a larger amount of fuel. The less flammable species were characterized by thick, heavy leaves that create dense fuelbeds, potentially inhibiting fire spread and the overall consumption of available fuels. Analyzing the dynamics between leaf traits and plant flammability with forest composition, successional trajectories and future fire behavior could lead to an examination of overall landscape effects in which certain species with fire-adaptive strategies could outcompete more fire-sensitive species, therefore influencing future fire regimes. Furthermore, given a scenario of increasing fire, this knowledge can lead to more effective conservation and land use policies in tropical regions.
