title: Trees for Food Security Project-Local Knowledge-Tree management and impact of management on trees’ phenology in Oromiya region, Ethiopia

description: This dataset was moved to: https://doi.org/10.34725/DVN/25245The research investigated the impact of management on the phenology of Acacia tortilis, Faidherbia albida, Croton macrostachyus, Dichrostachys cinerea and Ziziphus mucronata. The trees were selected, as they were dominant species, in two sites in a parkland system in Oromiya region, Ethiopia. The main purposes of this research were to elicit local knowledge about the effect of common management practices on phenology, the effect of management on tree – crop interaction and if management practices affects the tree size. Data mainly were collected by semi – structured interview and in combination with participatory research tools. This research found that pollarding, pruning and coppicing were three common management practices in both sites that farmers have a broad knowledge about them and they use from each one of these practices under the special circumstances for example they never do the pollarding when the trees are still so young. The farmers’ local knowledge suggested that the practice of pollarding was found to have a significant impact on the timing of flushing and flowering of all five species at both sites Tree management can change the tree - crop interaction. Except the managed F. albida trees, crops grow better under the other managed trees, as they have no shade and no water dropping on crops. Unmanaged F. albida has no leaf at the time of cropping but when farmers do the pollarding these trees start leaf flushing only 1 week to one month after pollarding and when they have leaves they have more light and water competition with crops so the crop productivity decrease under the managed F. albida.

title: Trees for Food Security Project-Local Knowledge-Using local knowledge to understand soil properties and land management in Ongobo bakanisa, Ethiopia

description: This dataset was moved to: https://doi.org/10.34725/DVN/25246To design appropriate interventions, it is essential to gain information about the types and the temporal and spatial changes of local soils in the target area and their interaction with trees. Information from soil maps is often not detailed enough to be operational and does not show soil variation within a landscape. The use of local knowledge can help gather information about the various soil types within an area. It does also reveal farmers view on soils and can help understand spatial and temporal changes. This study brings together two approaches to elicit local soil knowledge to inform the ACIAR project "Trees for food security". The AKT5 and InPaC-S methodologies were used to elicit farmers knowledge about soils and land management impacts. Objectives and research questions: Understand spatial and temporal changes of soil properties in the area. 1. Research question: How do farmers classify soils and what are their functions? 2. Research question: What is the spatial distribution of soils? 3. Research question: How did soils change over time? Understand farmers perception of soil soil quality and driving factors for soil quality changes 1. Research question: How do farmers evaluate soil quality? 2. Research question: How does soil management, crop management and trees change soil properties? Find synergies between the methodol oies AKT5 and modied bits of Barrios` InPac-S tool. 1. Research question: How can the two approaches AKT5 and InPaC-s complement each other?

title: Replication data for: Simulating impact land use change watershed services in Sasumua Watershed using SWAT

description: This dataset was moved to: https://doi.org/10.34725/DVN/25267Land use change has a major influence on the capacity of watersheds to produce watershed services such asimproving water quality and flood mitigation. The objective of this study was to simulate the effect of land usechange on the sediment and water yield in Sasumua watershed, Kenya using SWAT model. The SWAT modelwas calibrated and validated using recorded reservoir data. The validated model was then used to simulatewater and sediment yield under three scenarios of runoff curve number CN (improved land surface conditionCN-6, base case, degraded land surface condition CN+ 6). The CN was used as a surrogate to represent landsurface treatments that influence generation of surface runoff following rain events. The coefficient ofdetermination from the calibration of the model was 0.6 and 0.5 for the validation. An increase in CN by 6(scenario CN+ 6) units in the agricultural part of the watershed, increased the sediment loading to the streamsby 53.6% while a reduction by 6 units (scenario CN-6) reduced sediment loading by 34.3%. Scenario CN-6resulted in a 28.5% decrease in surface runoff, a 13.8% increase in base flow and a slight decrease in totalwater yield of 1.2%. On the other hand, scenario CN+ 6 increa sed the surface runoff by about 44%, reducedbase flow by 10.5% and increased the water yield by 6.5%. Improvement in land surface condition thatenhances infiltration is a feasible conservation measure to reduce soil erosion and subsequent sedimentation ofthe rivers and the reservoir. CN-6 can be achieved through terracing, contour farming, grass strips, better cropresidue management and well managed grazing

title: Replication data for: Households’ Willingness to Pay for Improved Watershed Services of the Layawan Watershed in Oroquieta City, Philippines

description: This dataset was moved to: https://doi.org/10.34725/DVN/25298Watersheds provide numerous ecosystem services to downstream communities often with no cost to them. Although these services are valuable to humans, they do not have monetary values attached to them, making their total economic value quite ambiguous. This ambiguity results in the non-optimal use o f the natural resources that leads to the degradation of the watersheds. One approach that could address this issue is payments for ecological services (PES). The main objective of this study was to estimate the willingness-to-pay for improved watershed services by domestic water users within the Layawan Watershed in Oroquieta City. It employed the contingent valuation method to assess the willingness to pay of water users. More than 50% of the respondents voted positively to the referendum question which is whether they are willing to pay a certain amount for the conservation of the Layawan Watershed or not. The computed mean willingness to pay amounts were Php 57.48 and Php 53.89 per month per household for the parametric and non-parametric estimations, respectively. These amounts translate to 0.68% of the average monthly household income of the sample respondents, which is approximately Php 8 198.84. The amounts computed may serve as bases for a water user fee that may be collected from the domestic water users in the Layawan Watershed as buyers of the watershed services.

title: Teak agroforestry systems for livelihood enhancement, industrial timber production, and environmental rehabilitation

description: This dataset was moved to: https://doi.org/10.34725/DVN/25256Teak is produced in industrial plantations in more than 43 countries. National and international demand for teak timber exceeds the sustainable yield from natural forests and plantations. High demand creates opportunities for enterprising farmers. Teak is now grown in smallholder' agroforestry systems in many tropical countries. These systems enable farmers to diversify production, reduce farm risk, contribute to food security, and generate much-needed income. They also meet commercial needs for timber and improve environmental conditions. This paper reports the contributions of teak systems to smallholders livelihoods in Indonesia, where farmers have been producing teak for over 50 years. Indonesian farmers cultivate teak as one component in integrated multispecies agroforestry systems. Annual cropping is an important aspect of these systems, producing commodities for both household consumption and market sale. Besides supplying food for households, smallholder teak systems provide 40% of household income from agricultural and timber crops. Teak and other tree crops allow households to re-allocate labor to off-farm employment when those opportunities are lucrative. However, farmers suffer from limited resources, labor, and access to information, which constrain the productivity of their teak sys tems. Specific recommendations are provided regarding how smallholders can adopt improved silvicultural and marketing management. Roles for government, support agencies, and industry that would provide benefits to all parties are outlined. Policy changes that would motivate smallholders to improve the management of their teak systems are identified. Conclusions and recommendations are applicable to smallholder teak systems across the tropics.

title: Assessing the willingness to pay for reliable domestic water supply via catchment management: results from a contingent valuation survey in Nairobi City, Kenya

description: This dataset was moved to: https://doi.org/10.34725/DVN/25265Shortage of domestic water is a key problem in Nairobi. The Sasumua Reservoir supplies 20% of Nairobi'ÃÂÃÂs water. However, reservoir water quantity has been impacted by human activities. Landholders within the catchment have no incentives to take into account this impact in their decision. The objective of this study was to estimate the willingness to pay (WTP) of Nairobi residents for reliable domestic water via catchment conservation. Data were collected through face-to-face surveys. A censored regression model was employed to estimate the WTP. Results show that monthly mean WTP of an average household is about 275 Kenya shillings; income , education, and age are the key variables affecting WTP; and lack of an appropriate institutional regime is the major public concern that could hinder implementation of market-based schemes

title: Africa RISING project: Local agro-ecological knowledge as a basis for sustainable intensification of tree- crop- livestock systems in the Ethiopian highlands: Sinana Woreda, Oromo Region

description: This dataset was moved to: https://doi.org/10.34725/DVN/25286This study provides results from local knowledge studies conducted in Sinana woreda, Oromo region. The local knowledge was used as a means of understanding fine-scale variation in a non-homogenous smallholder system in the wheat-belt of the Ethiopian highlands. The research was supported through the USAID funded project Africa RISING (Research in Sustainable Intensification for the Next Generation). The project was launched as part of the US government’s Feed the Future initiative to address global hunger and food security issues in key farming systems in sub-Saharan Africa. This study was focussed on identifying existing sustainable intensive agricultural methods in Sinana woreda, Oromo region. The study also collected local knowledge on agricultural methods so as to assist in the development and implementation of appropriately adapted technologies to intensify production of crops, livelihood and household production without extending the areas subject to cultivation. The research objectives of the study were: · To characterize agro-ecological knowledge of farmers in the Africa RISING project sites · To identify and map out community resources · To assess land use and livelihood strategies at the household level · To characterise existing tree cover and assess the drivers of tree cover change · To determine temporal variation in availability of provisioning services (income, fuel, livestock feed, crops, labour.)

title: Replication data for: Ethnobotany, propagation and conservation of medicinal plants in Ghana

description: This dataset was moved to: https://doi.org/10.34725/DVN/25619Medicinal plants and plant-based medicines are widely used in traditional cultures all over Ghana and they are becoming increasingly popular in modern society as natural alternatives to synthetic chemicals. This paper studied the ethnobotany of medicinal plants through a socio-economic survey. Seed germination experiments were also carried out on selected medicinal plant species. It was found that the herbal medicine industry was a major source of income for 82% of the respondents. Almost 50% of the respondents were women with majority of them involved in marketing of the medicinal plant products. Out of 160 plant species marketed, 129 were collected in Ghana with Kumasi and Accra being the major marketing centres. Most of the species have multiple curative properties with over 46 diseases purported to be cured by herbal medicine. Over 100 species were reported to be in high demand, scarce or unavailable. Among the reported constraints to availability of medicinal plants were lack of cultivation, unsustainable harvesting, deforestation, wildfire and urbanization. Studies on seed germination showed that seven species out of the ten selected for conservation had good germination, ranging from 40-74% with an average of 63.3%. This suggests the possibility of cultivating medicinal plant species on commercial scale. Based on the results, it is suggested that linkages between all stakeholders should be strengthened in order to promote conservation and commercial production of medicinal plants. Furthermore, improving the knowledge-base of scientists, traditional herbal medical practitioners, policy makers and the public on the relevance and safety of traditional plant medicine could lead to the sustainability of the medicinal plants industry in Ghana.

title: Replication data for: The influence of seed and oil storage on the acid levels of rubber seed oil, derived from Hevea Brasiliensis grown in Xishuangbanna, China

description: This dataset was moved to: https://doi.org/10.34725/DVN/24942High acid levels, characteristic of rubber seed oil (RSO), limit RSO use in biodiesel production. The aims of this study were to determine the causes of these high acid levels by investigating what affects the storage of rubber seeds and RSO had on the acid levels. Two storage conditions/methods were evaluated, one representing a proposed storage method (SM 1), the other mimicking storage conditions characteristic to the Xishuangbanna region (SM 2). Furthermore, RSO storage was evaluated by testing RSO acid levels over a 2-month period, under standard storage conditions. Seeds from SM 2 displayed increased seed pile temperatures, higher levels of Mildew infection, lower seed oil content and higher acid levels. Low seed oil content and high acid values of SM 2 were resultant of the high Mildew infection and increased seed pile temperatures. In addition, a critical value of 90% relative humidity of seed piles was identified, above which Mildew infection increased sharply. Storage of crude RSO resulted in increased acid values. This data shows that in order to reduce high acid values, seed pile temperature, humidity and Mildew infections need to be kept to a minimum, as well as the storage time of the seeds and the RSO.

title: Land use maps of Upper reaches of Changhua Watershed, Hainan

description: This dataset was moved to: https://doi.org/10.34725/DVN/25069To protect biodiversity and improve environmental conditions, China has invested billions of dollars in reforestation and payments for ecosystem service programs. Here, we examine the Sloping Land Conversion Program, the largest such programin the world and found that after 13 years of implementation at our study site, it has had negative impacts on natural tropical forests. GIS and remote sensing techniques revealed that both natural forests and natural shrub and grasslands were replaced by non-native monocultural plantations on Hainan Island, China, a key tropical biodiversity hotspot. Under current Chinese policy, these plantations are classified simply as forests, with the assumption that they are equivalent to natural forests. This lack of a distinction in forest quality has led to substantial deforestation and plantation expansion, including encroachment into protected areas on Hainan. Additional social and economic drivers of these changes were identified by examining the participants in this program and their actions. Without a new ecologically based definition of forests and new goals for reforestation, such programs designed to improve ecosystem services, and fores t quality may actually threaten remaining natural forests and other vegetation types in Hainan and in other areas of mainland China.

title: Africa RISING Project: Sustainable tree-crop-livestock intensification as a pillar for the Ethiopian climate resilient green economy initiative

description: This dataset was moved to: https://doi.org/10.34725/DVN/25253In 2012, Africa RISING funded an ‘early win’ project in Ethiopia led by the World Agroforestry Centre (ICRAF). The project aims to underpin the Ethiopian Climate Resilient Green Economy Initiative by providing early win tree species and management options for integrating fruit, fodder, fuelwood, fertilizer and timber trees in fields, farms and landscapes. This will enable sustainable intensification of farm systems by expanding the scope of options promoted by the initiative, and by targeting species and management options appropriately to sites and farmer circumstances. In the process, we will build a durable partnership amongst national and international institutions that will be well-placed to further refine the options available and their targeting. A novel aspect is bringing together tree, crop and livestock expertise to address the whole farm and landscape context. This is critical for the success of integrating trees in fields where they may compete as well complement crops, and where the management of livestock grazing is fundamental to the success of tree establishment. The outputs include: 1. Local knowledge about integration of trees in fields, farms and landscapes documented. 2. Best bet tree species and management options identified. 3. Needs for development of the tree seed and seedling supply sector assessed. 4. Effective partnerships for promoting tree-crop-livestock integration to underpin the climate resilient green economy initiative established.

title: Sugar palm (Arenga pinnata (Wurmb) Merr.) for livelihoods and biodiversity conservation in the orangutan habitat of Batang Toru, North Sumatra, Indonesia: mixed prospects for domestication

description: This dataset was moved to: https://doi.org/10.34725/DVN/25297Domestication of desirable forest resources in agroforestry is expected to contribute to community based forest conservation efforts, but there may be an optimum level of domestication in this respect. Aren or sugar palm (Arenga pinnata (Wurmb) Merr.) is a multipurpose tree that provides livelihoods for local people and food for other biota in the landscape. However, its domestication is still limited in many places, such as in Batang Toru Forest Block, an area of high conservation value, including habitat for the Sumatran orangutan (Pongo abelii). Options for aren management were prioritized as part of a landscape-scale conservation study by comparing domestication levels in the area. Data on economic indicators and ecological knowledge were gathered through interviews with key farmers, focus groups and transect walks. Four representative villages were selected for the study, that is, (i) two villages with no domestication of aren; and (ii) two villages with aren cultivation in rubber-based land-use systems. Costbenefit analyses suggested that in a rich biodiversity area, such as Batang Toru, although aren was one of the sources of local livelihoods, additional investment for domestication beyond cultivation was not an option considered by farmers. Farmers still perceived wildlife as an efficient mode of aren regeneration, supported by the coexistence of people and other biota in the area. It appears the value of aren for local people'ÃÂs livelihoods and conservation can be enhanced by increasing its stocking density. There is also scope for improving market access and share of end-user value received by farmers.
