title: Integrating Livelihoods and Multiple Biodiversity Values in Landscape Mosaics

description: This dataset was moved to: https://doi.org/10.34725/DVN/2JHSZNThe project, “Integrating Livelihoods and Multiple Biodiversity Values in Landscape Mosaics (or the Landscape Mosaics Project in short)”, was the first project of the CIFOR-ICRAF Biodiversity Platform. The project conducted research on socio-economic, governance and biophysical characteristics and dynamics of the five study landscapes and the interactions between these factors. It also investigated the potential for reward mechanisms for environmental services. The project aimed to in form and facilitate negotiation processes on natural resource use rights allocation between communities and district level and other key stakeholders in order to enable them to manage landscape mosaics more sustainably. The project worked in the following study sites: Tanzania: East Usambara Mountains, Tanga Region; South West Cameroon: Takamanda-Mone Technical Operation Unit; Sumatra, Indonesia: Bungo District, Jambi Province; Northern Laos: Vieng Kham District, Luang Prabang Province; and Eastern Madagascar: Manompana corridor, Soanierana-Ivongo District. Within these countries, a landscape was selected that reflected a gradient from a densely forested protected area to land covers fragmented by agricultural uses. From these landscapes, three representative territories (villages) were selected in which the support to negotiations and empirical research took place. The project was funded by the Swiss Agency for Development and Cooperation and supported by other donors such as the European Commission, the Governments of Finland, the Netherlands and Australia. The Biodiversity Platform was launched in 2006 as a joint initiative of CIFOR and the World Agroforestry Centre. The Platform was launched in recognition of the role that multifunctional landscape mosaics have in preserving biodiversity conservation, both within and outside of protecte d areas. Tree cover in multifunctional landscape mosaics preserves important habitats and can play a crucial role in maintaining connectivity between large reserves, which has been demonstrated to be essential for the survival of many species. The occupation and use of these landscapes by many peoples, however, require that any conservation efforts in these mosaics consider the social dimensions of the use and conservation of biodiversity, in addition to their biophysical dimensions and dynamics.

title: Antecedent and effect of group sales on supply chain performance: The Case of Kola production and Marketing in Cameroon

description: This dataset was moved to: https://doi.org/10.34725/DVN/9HHJY9Kola plays an important role in the livelihoods of people in the North West region of Cameroon. However, the potential benefits of the product have not been fully exploited due to many problems including ineffective marketing techniques. In an attempt to address this problem, some organisations like the World Agroforestry Centre (ICRAF) have facilitated the producers of kola to embark on group sales as a means to improve their marketing performance. During the first 5 years of implementation of this programme, there was no clear picture about the impact of the marketing intervention programme on the marketing performance of the farmers. This paper discusses the main antecedents and producers’ perception of the effects of the group sales on the supply chain performance of kola producers in Cameroon. Using open ended interviews with 50 farmers, the paper reveals that group sales has the potential to improve kola supply chain performance through increase in prices, quantity harvested and sold, and increase in number of producers involved in the group.

title: CAWT Survey: Scaling-up the science and practice of conservation agriculture in sub-saharan Africa

description: This dataset was moved to: https://doi.org/10.34725/DVN/BJKHI0An evergreen revolution is required in sub-Saharan Africa where increased human and livestock activities have led to the collapse of conventional soil conservation systems and increased land degradation soil compaction, nutrient and organic matter depletion, reduced water holding capacity and microbial activity. The proposed project is premised on the hypothesis that integrating trees with conservation agriculture has the potential to enable smallholder farmers attain resilient evergreen agriculture leading to more sustainable production and agro-ecosystems, and hence contribute to poverty reduction and increased food security while enhancing the resilience of systems in the face of climate change. However, for CAWT to become a reality for smallholder farmers in SSA there are several gaps in knowledge that must be filled. Information is lacking on the drivers that have made some countries succeed in scaling up CA, the constraints they face and how they address them, lessons learnt and how to advance success to larger scale impacts. The complementary effects of trees on CA under different environmental conditions are not well documented. Other issues include knowledge on how long term access to land, availability of inputs, appropriate CA implements, adequate extension support and advice, and institutional and policy support influence adoption of CA. Empowering, adaptive and participatory, bottom-up research and extension approaches are essential to stimulate more farmers to test and adopt CA and agroforestry for sustainable production intensification. The overall goal of the CAWT initiative is to promote a continental wide adoption of conservation agriculture and agroforestry to sustain the productive potential of the natural resource base, improve incomes, foods security and livelihoods of smallholder farmers in sub Saharan Africa.

title: Replication data for: Development pathways in medium-high potential Kenya: a meso-level analysis of agricultural patterns and determinants.

description: This dataset was moved to: https://doi.org/10.34725/DVN/LJAGXFSample aerial photographs used were obtained from Department of resource surveys and remote sensing (DRSRS) for the year 1997. The photography was done between the months of May June July after the long rains and when the maize crop has taslled. The photos are obtained using an aircraft flying at 1500m above ground level and equipped with a 35-mm camera, a 200mm lens and a 200 Ektachrome film. The slides produced are projected onto a 100 Dot grid paper on a wall and analysed for land use land cover and any other land parameters required. The number of times a certain use or cover type corresponds with the dot is recorded as the percentage cover for that type. The other parameters as mentioned in the introduction were directly counted on the projected slide and recorded as described later. A total of approx. 5700 slides were interpreted. The information was recorded and entered into computer using Access data entry forms and saved in Excel Format. The objective of the project was to interpret the 1997 land use / land cover Low level flying Aerial Sample Photos to derive the following information, a.)Percentage land use / land cover estimates for 5,747 aerial photo slides according to categories identified in Table 2 of the document b.)The number of mabati houses, thatched houses, houses with or presence of electrical poles, houses adjacent to or presence of streams or irrigation channels, number of schools, worship houses and factories. c.)The number of gullies d.)Percentage tree canopy cover e.)Percentage area under severe soil erosion

title: Data for: Two kinds of authigenic xenotime overgrowths in response to an Early Paleozoic tectonothermal event in South China

description: This study has documented two kinds of xenotime overgrowths from the Cryogenian-Ediacaran sedimentary rocks in South China. The identical tetragonal dipyramidal structures prompted one type of xenotime to overgrow detrital zircon grains, whereas the other type coexists with rutile crystals. SIMS Pb-Pb, NanoSIMS, EPMA, and TEM imaging analyses suggest these xenotime overgrowths, together with their rutile substrate could be of hydrothermal origin; formed by means of percolating fluids leaching ilmenite and REE(Y) bearing silicate minerals. Iron, Ti, and REE(Y) ions leached in this way were combined with O, S, and P anions to precipitate rutile, xenotime, iron oxides, and pyrite in other pore spaces. Such fluid induced activities were probably induced by the ca. 460-390 Ma Wuyi-Yunkai Orogeny in South China. The most important finding is that the rutile-xenotime assemblage was precipitated almost simultaneously, rendering a dissolution-reprecipitation process impossible. Absence of dissolution margins on detrital zircons suggest detrital Fe-Ti oxides are more prone to be leached by fluids than zircon grains, probably because the latter has more stable chemical properties.

title: Data for: Forms of thought by hand in the hospital administrative environment.

description: The use of paper with the AUX20 stain acts as a mechanism that maximizes or optimizes the perception of time. This could be done only in a psychological way. But it is indisputable that the human psychological recognizes the physical life as something to be interfered with. The use of stained paper plus the use of the internet, which makes analogy to ancient rock paintings, elucidates a physical science that can be classified as logical writing and mathematics. Promoting economy.

title: Replication data for: Farmers' preferences for tree functions and species in the West African Sahel

description: This dataset was moved to: https://doi.org/10.34725/DVN/T6G2THParkland agroforests are mixtures of trees and shrubs that farmers select for certain functions and cultivate together with staple food crops. In the West African Sahel, parkland trees and shrubs provide essential products and services for rural communities, and thereby contribute to poverty alleviation and food security. The principal products include wood for energy, construction, furniture, household and farm implements; fruits and leaves for food; numerous traditional medicines; fibers for roofs, mats and fencing. Environmental services of parkland trees and shrubs, such as soil and water conservation, are crucial because the region is semi‐arid and the soils are generally infertile. A participatory project to improve the management and productivity of native tree and shrub species in parkland agroforests was initiated in the West African Sahel in 2006. The first major activity was to determine farmers’ preferences for tree functions and the priority species for these functions. In this paper, we present results of preference surveys conducted in Burkina Faso, Mali, Niger and Senegal.
