title: Land Health: Land health surveillance system in support of Malawi food security project

description: The World Agroforestry Centre (ICRAF) with funding from the Irish Aid Malawi, has been implementing a four-year nation-wide programme known as the Agroforestry Food Security Programme (AFSP) in 11 districts and eight Agricultural Development Divisions (ADDs): Shire Valley, Blantyre, Machinga, Lilongwe, Salima, Kasungu, Mzuzu, and Karonga ADDs since its inception in January 2007.  The AFSP has six specific objectives as follows:     Target, prioritize, adapt and demonstrate fertilizer, fodder, fruit and fuel-wood trees portfolio options in eleven selected districts with suitable biophysical, geographical and social niches for agroforestry interventions, including vulnerable sub-populations (HIV/AIDS afflicted, food insecure, poor, women);     Engage partners in developing and applying strategies for sustainable supply and delivery systems of quality tree germplasm to meet massive demand by smallholder farmers;     Engage, mobilize and sensitize policy makers to formulate appropriate policy mechanisms and instruments for mainstreaming agroforestry and catalyzing its adoption at the district and national levels;     Improve strategies for accessing functional and equitable input markets and market support systems for agroforestry products that increase prices paid to farmers for their outputs and reduce costs incurred by farmers for needed inputs;     Strengthen and mobilize the capacity of national and local institutions and development agencies in sc
aling up agro-forestry and develop strategies for institutionalizing agroforestry research for development in Malawi;     Mainstream agro-forestry into national development plans and community based land-use and management practices.

title: Replication data for: Positioning fruit trees into climate change / variability scenarios: opportunities and constraints in the placement of fruit tree species in payment for environmental services.

description: Extreme environmental conditions due to climate change or variability are a threat to crop production, productivity and livelihoods. Thus, providing alternative livelihoods to communities, especially the rural masses remain an important catalyst in reducing poverty, food insecurity and deforestation in the development of climate change/variability scenarios. This is critical in southern Africa where poverty, deforestation rate and food insecurity are high. These are challenges that rural development programs abating impacts of climate change/variability must address. Planting trees including those outside the forest has been a possible climate change mitigation or adaptation measure.   Surprisingly, planting fruit trees have been given little attention and have always aligned to food security, but not their contribution to carbon sequestration and payment for environmental services (PES). There have been limited research studies quantifying carbon sequestration capacities in diverse fruit tree species. This contributes to low profile of fruit tree species in carbon trading. While the emphasis has been on forest trees, those trees outside the fore
st have also a role to play, especially with proper fruit orchard management systems and propagation protocols that maximize carbon reservoirs.   This paper reviews the role of fruit trees in the context of carbon quantities sequestered and the reasons they should be considered in PES or better still carbon trading. It is envisaged that proper fruit tree orchard management practices and propagation protocols can be designed to increase carbon sequestration, while gaining some socio-economic benefits. We hypothesize that proper management of fruit trees offers an opportunity to extend and maximize fruit productivity and carbon storage over a long period. This provides a diverse development option within the framework of climate change/variability mitigation/adaptation. Planting fruit tree species presents many opportunities, but there are still limited documented research studies and piloted projects on any form of PES, especially carbon trading. It is clear that many research studies are warranted to quantify carbon storage within diverse fruit orchards and under different management systems.

title: Replication data for:  No appropriate technology so far for Ricinodendron heudelotii (Baill. Pierre ex Pax) processing in Cameroon: Performance of mechanized kernel extraction

description: Ricinodendron heudelotii kernels are an important source of income for rural wome
n in the humid tropics of Africa. Manual kernel extraction is time consuming and efforts have been made to mechanize the process. However, mechanical damage to kernels remains an issue. Within the socioeconomic and resource ecology context in the central region of Cameroon, a prototype machine for extracting njansang kernels was developed and has been tested since 2007, then evaluated using a learning selection model. Surveys with users and non-users suggested a shift towards male and younger users. The advantages of rapid kernel extraction are partly offset by the requirement to sort out broken kernels, leading to a total time requirement of 60.87 min for manual processing and 2.08 + 39.56 min for mechanical extraction + manual sorting. The technology needs further improvement to deliver the expected increase in labour efficiency and economic advantages for rural women. The study was carried out in the small community of Epkwassong, 42 km from Ayos city, Nyong-et-Mfoumou Division in the Central region of Cameroon. Epkwassong was chosen because njansang is common here and women in the village have a good knowledge of its exploitation. The njansang producer group âFaâa Si Obeâ is well-organized and has been selling njansang as a group since 2005. In terms of socio-economic and biophysical characteristics, Epkwassong is in many ways representative of the humid forest zone of Cameroon, and even of the Congo Basin. Epkwassong is located in a forest zone with bimodal rainfall l(1500 to 2000 mm per year in average) characterized bya Guinean climate with 4 seasons (main dry season from December to February; main rainy season from March to June; short dry season from July to August; short rainy season from September to November). The average temperature is 25Â°C and the main economic activities of the area are agriculture, artisanal fishing in the rivers Nyong-et-Mfoumou and hunting.  Commercialization of njansang is the fourth most important source of income after plantain, cocoa and cocoyam.  R. heudelotii in this zone is typically found in abandoned farmland and is often retained when land is cleared for farming because it improves soil fertility and provides shade required for cocoa cash cropping.

title: DIVERSITY OF BIRDS ACROSS LAND USE AND HABITAT GRADIENTS IN FORESTS, RUBBER AGROFORESTS AND RUBBER PLANTATIONS OF NORTH SUMATERA

description: Birds play a pivotal role in ecosystems, but in disturbed areas their role may be limited due to the changes of their natural habitat. This paper studies the birds habitat in Simalungun and Asahan districts, North Sumatera. The study was conducted in four habitats: natural forest, rubber agroforests (RAF), rubber monoculture plantations (RMP) and emplacement areas (EA). The birds were observed using descriptive survey methods by implementing a quick biodiversity survey, data were collected along one km transect.  The results showed that in total, 142 species of birds from 42 families were observed in the four habitats. Natural forests had the highest diversity of bird species, followed by rubber agroforests, emplacement areas and rubber plantations, with a Shannon-Wiener index of 3.8, 3.6, 3.0 and 2.5, respectively. Regarding the IUCN red list species, 12 bird species of near-threatened status and 2 species of vulnerable status were recorded.  Based on CITES categories, one species was listed in the Appendix criteria I, 12 species were classified in Appendix II and 26 bird species were protected under Indonesian regulations. Changes in the structure and composition of vegetation in disturbed forests and cleared land determined the richness of bird species. The different tree compositions in the four habitats of the rubber estate plantations and surrounding areas influence the number of bird species, bird diversity and species composition.

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

description: The 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.<br>
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. <br>
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: Replication data for: Plant elemental composition and portable X-ray fluorescence (pXRF) spectroscopy: quantification under different analytical parameters

description: Emergence 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>0.90) for light elements (Mg to P). Sulfur, K, and Ca can be reliably measured without the aid of a vacuum (R2>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: Genetic Variation of Kenyan Populations of Warburgia ugandensis, an Important East African Highlands Medicinal Tree Species

description: Warburgia ugandensis is an important medicinal tree species in Eastern Africa used to treat several ailments. Wild populations are under great threat due to unsustainable harvesting for medicines and indiscriminate felling of trees for timber and firewood. There is an urgent need for developing and implementing conservation strategies of this species and information on genetic structure is a crucial input. Analysis of molecular variance (AMOVA), which employed 141 AFLP markers revealed most genetic variation to be among individuals within populations (59%, P is less than 0.0001), but variation among populations (41%, P is less than 0.0001) was highly significant as well. Constrained ordination analysis illustrating the relationship among populations showed a clear distinction between W. ugandensis from Uganda and western Kenya and other W.
ugandensis populations. No correspondence was shown in some cases on pair-wise genetic distances and geographic distances among populations. These findings suggested that conservation strategies for the species in Kenya should place relatively more emphasis on the revealed genetic structuring within the country.

title: Household and farm attributes affecting adoption of smallholder timber management practices by tree growers in Gunungkidul region, Indonesia

description: Farm household characteristics determine the success of programs promoting agroforestry systems and practices. This paper reports household and farm factors affecting the adoption of timber management practices by smallholders in the Gunungkidul region, Central Java, Indonesia. The research used three logistic regression analysis models - based on each household and farm characteristic, and a composite of both together - to identify the key factors influencing farmers' adoption and management decisions, and their relative importance. A sample of 152 farmers who managed their trees primarily for timber production was compared to a sample of 115 farmers with similar socio-economic characteristics who did not. The household condition and composite models identified both on-farm and off-farm gross incomes as significant factors affecting farmers' decisions to manage timber trees. The models confirmed that farmers with larger farms, and with higher on- and off-farm incomes, were more likely to manage their trees for timber production. These results have implications for extension programs that promote adoption of commercial timber management by smallholders in the case study and similar regions.

title: Scaling up agroforestry requires research ‘in’ rather than ‘for’ development

description: Recent high-level policy papers call for scaling-up agroforestry to sustainably increase agricultural production and maintain environmental services. Evidence suggests that this will not be achieved by wide scale promotion of a few iconic agroforestry practices. Instead, three key issues need to be addressed. First, fine-scale variation in social, economic and ecological context and how this creates a need for local adaptation. Second, the importance of developing appropriate service delivery mechanisms, markets, and institutional contexts, as well as technologies. Third, appropriate research design, within the scaling process, that enables co-learning amongst research, development and private sector actors. This requires a new paradigm that builds on previous integrated systems approaches, but goes further, by embedding research centrally within development praxis.
