title: Sygnola Tsafack and Ann Degrande (2015) The Value of Printed Sources of Information in Agricultural Extension Case Study on “The Farmer’s Voice” in Cameroon, MEAS Evaluative Case Study

description: Various methods are used to provide extension workers and farmers with agricultural information. Printed materials remain a major source of information, despite digitalization of information networks, but few studies have looked at their effectiveness. The present work characterizes and assesses the effectiveness of The Farmer’s Voice (TFV), an agricultural newspaper in Cameroon. Data were collected using a semi-structured questionnaire from 107 randomly sampled readers (mainly farmers, lead farmers and extension workers) in three regions.
Most respondents subscribed to TFV and paid fees themselves. The time readers took to read completely the magazine varied with gender, reader category, and education level. Respondents recalled topics such as technical tips and health/nutrition much more than others. For 94 percent of users, the motivation to read TFV was to learn appropriate practices on production, consumption, and marketing.
Though TFV was a complementary source of agricultural knowledge for most respondents, 97.2 percent were using information from this magazine on a day-to-day basis. Most respondents kept copies of TFV, mainly for future reference. More women than men and more subscribers than occasional buyers preserved copies.
All respondents agreed that TFV had significantly contributed to changes in their farming practices. For farmer trainers, TFV was very useful in their extension and advisory activities. Though more than four-fifths of readers had learned about new farming practices through TFV, 27.2 percent were not able to master some of the techniques described in TFV. The difference can be explained by their low education level. Around one-third of respondents said they were willing to share information with others through TFV; very few (11.5 percent) had written to the journal.
The majority of users found TFV easy to read and understand. The current price was just about right for 52.8 percent of readers, and 76.8 percent said the quality of the journal was good. Less than one-fourth of respondents (23.4 percent) were able to specify a journal that could substitute for or complement TFV. Most users of TFV (83.5 percent) confirmed that the content of the journal is relevant to all types of farmers. The average score of the general effectiveness of the TFV was 8 out of 10 (min = 5, max = 10, median = 8).
The majority of subscribers complained about not receiving their monthly issue on time. Distribution coverage was also low, especially in the rural areas and in towns where there is no official distributor. Some respondents criticized TFV for not sufficiently dealing with topics such as fund-raising, agroforestry and processing of agricultural products.

title: Replication data for: Management, use and ecology of medicinal plants in the degraded dry lands of Tigray, Northern Ethiopia.

description: An ethnomedicinal study was conducted to document the indigenous medicinal plant knowledge on the management, use, and ecology of locally important medicinal plants in Tigray, Northern Ethiopia. Ethnobotanical data were collected from 250 people, using semi-structured questionnaires, field observation and informal disc
ussion. The ethnomedicinal use of 259 plant species mainly herbs (31 to 51%), shrubs (31 to 46%) and trees (13 to 39%) used to treat 147 human and livestock ailments were documented in the study area. The most frequently used plant part were roots (49%), followed by leaves (37%) and bark (14%)... Crushing (59%), homogenizing with ingredients (17%) and chewing (14%) were the commonly used forms of herbal preparation. Drinking (45%), smoke inhalation (12%) and tie and hold on (10%) were the most frequently used methods of application. Most of the medicinal plants are collected from the wild. The use of more than one species was reported for remedy preparations and some health problems were treated by more than one medicinal plant. Our result showed that the local communities give less attention for the management of medicinal plants as local communities consider medicinal plants as wild, have unattractive market value and lack of knowledge. The mismanagement together with loss of habitat showed that ethnomedicinal plant species used by healers are under serious threat which indicates the need for urgent attention towards their documentation, conservation and sustainable utilization.

title: Replication data for: Are coffee agroforestry systems suitable for circa situm conservation of indigenous trees? A case study from Central Kenya

description: Coffee agroforestry systems (CAFS) are often considered to be species-rich, potentially contributing to the conservation of indigenous trees. To investigate the conservation capacity of a Kenyan CAFS, all tree species on 62 smallholder coffee farms (covering 39 ha in total) in the Aberdare Mountains of Central Kenya were recorded. In total, 6,642 trees of 59 species were enumerated, with a mean density of 256 trees per ha and a mean species richness of 11.2 species per farm. Indigenous species represented 63 % of the richness but only 31 % of the abundance. For individual farms, as expected, farm size had a positive correlation with tree species richness, but more interestingly there was a negative correlation with tree density. Cluster analysis based on densities of the 18 most important species (defined by an importance value index) revealed two groups of farms: one cluster represented small farms (mean size = 0.4 ha) with high tree species diversity and individual density, particularly of indigenous trees; the other cluster represented large (mean size = 1 ha) and less diverse farms with low tree densities, particularly regarding indigenous species. Tree individuals were unevenly distributed within farms, being more frequent in living fences (38 % of all individuals), the garden zone (
20 %) and in coffee plots (18 %). The relative occurrence of indigenous species was also uneven, being greater in living fences and the garden zone. Most adult trees (83 %) were planted, but only 46 % of seedlings were, revealing the active removal of volunteer seedlings by farmers as trees mature. Surveyed coffee farms harboured 20 % of the 135 tree species of the potential natural vegetation for the region, but only 3.6 % of the on-farm tree individuals belonged to the most valuable types of dominant and forest vegetation. Thus, although a source of significant tree cover and heterogeneity at landscape level, the value of these CAFS as circa situm reservoirs of forest tree species is questionable.

title: Replication data for: Locating REDD: A global survey and analysis of REDD readiness and demonstration activities

description: Mechanisms that support reduced emissions from deforestation and forest degradation (REDD/REDD+) have potential to counteract a large share of global greenhouse gas emissions if implemented effectively across the tropics. In 2007 the conference of parties to the United Nations Framework Convention on Climate Change called upon parties and international organizations to promote REDD through investments in capacity building and demonstration activities. This prompted many new actors to become involved in REDD activities at a variety of locations and scales. A global survey of REDD activities was undertaken in 2009 to enable better understanding of the intensity and geographic distribution of these activities. Existing compilations, literature review, web-based sources, face-to-face and telephone interviews, and e-mail questionnaires were used to compile data for the inventory. Inter alia, data were collected on the location of activities and official and unofficial factors influencing location choices. Inventory data were combined with secondary data to estimate a statistical count model (Poisson) of factors affecting the number of REDD activities undertaken in the 64 developing countries that experienced significant emissions from deforestation. The results show that there were at least 79 REDD readiness activities and 100 REDD demonstration activities as of October 2009. Of these, the largest shares of REDD readiness and demonstration activities were implemented in Indonesia (7 and 15 respectively) and Brazil (4 and 13 respectively), countries widely agreed to have the greatest potential for re
ducing forest-based emissions. The statistical results found no national characteristic to have a statistically-significant effect on the number of REDD readiness activities, but five national characteristics to have significant effects on the number of REDD demonstration projects. Baseline CO2 emissions, forest carbon stock, number of threatened species, quality of governance, and region all had significant effects. The results reveal the importance of biodiversity and good governance, and the relative unimportance of human need and opportunity cost of land. The results also reveal a bias against Africa and toward Latin America. Unless this pattern is countered, REDD and REDD+ may have geographic biases that undermine its broad political support.

title: Towards an Evergreen Agriculture in Africa: Scaling-up Conservation Agriculture with Trees for improved Livelihoods and Environmental Resilience in Eastern and Southern Africa

description: An 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 â 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: Agent-based Social Simulation of Government Incentives for Diversifying Rubber in Yunnan, China

description: Monoculture rubber plantations are conquering Southeast Asian landscapes at an unprecedented  rate.  The  district  of  Xishuangbanna  is  not  only  the  epitome  of  Chinese
biodiversity but also China's cradle of rubber framing. Driven by accelerated rubber demand  and rising rubber prices, large forest areas have been converted into rubber plantations. This leads to a clash between the political goal to conserve biodiversity and heritage landscapes - both driving the rapidly emerging tourism industry -  and economic aspirations at household and  district  levels.  Currently,  policy  options  are  discussed  to  change  incentives  that  better balance conserva
tion and economics. The policy process invited this research to inform the political debate. One of the methods used d
uring this participatory process was agent-based social  simulation,  revealing  a  few  surprising  insights  in  potentially  perverse  outcomes  of payments  for  ecosystem  services  to  convert  monoculture  rubber  into  green  rubber.  As  an outcome  of  this  modeling-based  initiative  the  current  debate  revised  previously  drafted payment schemes and reconsiders regulatory approaches.

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

description: To 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: Optimum Pruning Strategies for Reducing Crop Suppression in a gmelina-maize Smallholder Agroforestry System in Claveria, Philippines

description: On-farm trials were conducted to assess the effects of four branch pruning levels on maize grain yield, tree growth and stem shape. The experimental plots consisted of gmelina (Gmelina arborea R.Br.) trees planted at 1 x 10 m with maize intercropped in the 10 m-wide alleys between lines of trees. Pruning levels consisted of retaining a live crown ratio of 60-Â70% (T1), 40-50% (T2); 30-40% (T3) and of 20-30% (T4). At the end of the experiment, the total maize grain yield was highest under the high pruning intensity (T4) (18.06 t ha-1) and lowest under T1 (14.48 t ha-1). Maize grain yield under the pruning regime T2 and T3 were 16.08 and 17.21 t ha-1 respectively. Mean annual increment (MAI) in tree diameter was greater (5.0 cm yr-1) under T1 than those at T4 (4.1 cm yr-1). Pruning regimes T2 and T3 resulted in a MAI of 4.7 cm yr-1 and 4.5 cm yr-1 respectively. Financial analysis showed that maize-tree systems under T4 were more profitable than under T1 as long as the reduction of the average dbh at harvest were not greater than 1 cm. Pruning trees intensively also generated greater returns from labour than moderate pruning, as the greater maize grain yields under T4 compen
sated for the cost of pruning and the lower timber yield. In the context of resource-poor farmers, intensive branch pruning was a practice that prolonged the period of profitable intercropping and was compatible with commercial timber production.

title: Influence of clone provenance, branch diameter and positioning on the rooting ability of Dacryodes edulis macot in sourthen Cameroon.

description: In the process of participatory domestication of agroforestry species, one of the objectives is the conservation of genotype of fruit trees commonly used by local people and the overpower of their reproductive system. For this, techniques of vegetative propagation (tissue culture, grafting, cuttings and air layering) are applied
to those species which include the safou (Dacryodes edulis "G. Don" HJ Lam.) (Burseraceae), which is a forest tree native to tropical and equatorial Africa. It plays an undeniable role in the lives of Farmers. In addition to its fruit eaten as a food supplement, its wood is used for heating and contribution of traditional medicine should not be overlooked.   The objective of this work is to identify clones that are better suited for air layering and assess the effect of the diameter of the marcots on its ability to take root. To achieve these objectives, 12 clones and two diameter classes (2-3 cm and 3-5 cm) were tested in this trial conducted following a randomized complete block.
