ABSTRACT Many rural dwellers in tropical regions depend on non-timber forest products (NTFPs) for their livelihood and income requirements. However, the link between the economic benefits of NTFPs and their resource base (including local availability and sustainability) and sources are poorly understood. Understanding the dependence on NTFPs requires an economic valuation to improve on sustainable utilization and planning of NTFP resources in the forest. Further, NTFPs are undervalued and not be included in the national accounts therefore lowers overall contribution of forests to the GDP. The current study, therefore, estimated the value NTFPs from The South Nandi forest reserve, using a combination of methods. Twenty-two NTFPs and associated plant species used were cited in Focused Group Discussion, but it was firewood, grazing and medicinal plants that were mostly utilized. The collection of NTFPs took 54.5% of the households’ productive time suggesting high dependence on them. The economic value of NTFP extraction household−1 yr−1 was US$ 579.51. The annual firewood extraction was 7 285.4 ± 1 586.9 kg household−1 and households spent an average of 2.9 ± 1.2 hours to collect a headload of firewood. The net economic value for grazing cattle in the forest yr−1 household−1 ranged from US$ 11.6 to US$ 205.0. NTFPs contributed between 32.7% and 48.7% to households’ income confirming the importance of NTFPs to their livelihoods. This forest should be managed based on the principles of sustainable forest management for continued provision of these benefits.
热带地区的许多农村居民依靠非木材林产品(NTFPs)维持生计和收入需求。然而，对非森林保护区的经济利益与其资源基础(包括当地的可得性和可持续性)和来源之间的联系了解甚少。了解森林对非森林植被的依赖，需要对非森林植被资源进行经济评估，以提高森林中非森林植被资源的可持续利用和规划。此外，国家森林保护区的价值被低估，没有列入国民核算，因此降低了森林对国内总产值的总体贡献。因此，本研究采用多种方法对南南迪森林保护区的非森林保护区价值进行了估算。在focus Group Discussion中引用了22种ntfp及其相关植物，但利用最多的是薪柴、放牧和药用植物。收集ntfp占用了农户54.5%的生产时间，表明农户对ntfp的依赖程度较高。NTFP提取家庭- 1年- 1的经济价值为579.51美元。年采柴量为7 285.4±1 586.9 kg户- 1，平均耗时2.9±1.2小时。在森林中放牧牲畜的净经济价值在11.6美元至205.0美元之间。非森林保护区对家庭收入的贡献在32.7%至48.7%之间，这证实了非森林保护区对其生计的重要性。应该根据可持续森林管理的原则来管理这片森林，以便继续提供这些利益。

ABSTRACT Nyandarua County has enormous milk production potential and has a large amount of milk, because of large a population of dairy cows coupled with the huge milk market demand from within and without. Despite this potential, milk postharvest losses have posed a major challenge to the dairy sector in the county. The general objective of the current study was to establish causes of losses among milk producers, as well as factors that contribute to the choice of a milk-marketing channel. A total of 188 milk producers were selected through proportionate to size sampling from Nyandarua North subcounty, including the formal and informal milk value chains. A statistical analysis, as well as a quantitative analysis was done with the help of Microsoft Excel, STATA and SPSS Ver. 21. The first step Heckman results indicate that age of household head, gender of household head, education level, breed type, total milk output, feeding system, keeping of records and type of milk container significantly influenced the choice of milk-marketing channel. The second step Heckman results suggest that dairy farming experience, distance to milk collection point, type of breed, total milk output, use of detergent to clean milk containers, feeding system and keeping of production records were significant as far as causes of milk losses among milk producers was concerned. Based on the results of the current study, it is recommended that policy implementers and dairy stakeholders should prioritise efforts to minimise postharvest milk losses considering that the implications of these losses directly affect the economic wellbeing and livelihood of farmers and other dairy chain participants. Milk-marketing channels, both formal and informal, need to be re-evaluated based on returns and convenience with emphasis on proper postharvest milk management and handling. This will reduce on the losses and additional cost incurred by milk producers and transporters resulting to higher economic returns for the respective chain participants in the dairy value chain.

ABSTRACT The study was carried out at the Kenya Agricultural and Livestock Research Organisation (KALRO) Centre at Mtwapa to assess the effect of shade on the productivity of a maize–cassava intercropping system and on the contribution of the intercropping system to food and feed during the dry season, as well as to income. Maize and cassava crops were established in two plots measuring one hectare each. One plot was established in the shade to mimic crop production under tree crops, which is characteristic of coastal Kenya. The second plot was established in an open area. There were no significant differences (p > 0.05) between the yields in the shaded and unshaded plots for all cassava products with the exception of cassava leaf yield, which was higher (p < 0.05) in the shade, (1.67 vs 1.25 t ha−1). In contrast, all the maize products differed (p < 0.05) between the shaded and unshaded treatments. Shade reduced maize grain and bran yield by 48% and stover by 29%. It was estimated that the grain yield in the shade (2.38 t ha−1) would feed a family of 10 people and leave a surplus of 1.4 t ha−1 for sale. The marketable cassava in the shaded and unshaded treatments (19 and 22 t ha−1) could be sold for KES 317 720 and KES 323 600, equivalent to US$ 3 488 and US$ 3 553, respectively. The unmarketable cassava roots (8.5 and 9.59 t ha−1), plus the maize bran (0.11 and 0.21 t ha−1) from the shaded and unshaded treatments could be an adequate energy supplement for seven to eight cows (400 kg live weight) annually. Maize stover (1.5 to 2.1 t ha−1) could be fed to 7–9 cows for 53 to 65 days. The cassava leaves would provide protein supplement for one to two cows per year. Maize–cassava intercrop systems would, therefore, contribute to food and feed security and increase incomes in coastal Kenya.
肯尼亚农畜研究组织(KALRO)在Mtwapa中心开展了一项研究，旨在评估遮荫对玉米-木薯间作系统生产力的影响，以及该间作系统在旱季对粮食和饲料以及收入的贡献。玉米和木薯种植在两块土地上，每块面积为一公顷。在阴凉处建立了一个地块，模拟树木作物下的作物生产，这是肯尼亚沿海地区的特点。第二个地块建立在一个开放的区域。除遮荫区木薯叶产量高于无遮荫区(1.67 vs 1.25) (p < 0.05)外，遮荫区木薯叶产量均无显著差异(p > 0.05)。遮荫处理与未遮荫处理的玉米产量差异显著(p < 0.05)。遮荫使玉米籽粒和麸皮产量降低48%，秸秆产量降低29%。据估计，遮荫下的粮食产量(2.38 tha - 1)可以养活一个10口之家，剩余的1.4 tha - 1可供出售。遮荫处理和无遮荫处理(19和22 t ha - 1)的可售木薯的售价分别为317720和323600 KES，相当于3 488美元和3 553美元。遮荫和不遮荫处理的未上市木薯根(8.5和9.59 t公顷- 1)，加上玉米麸皮(0.11和0.21 t公顷- 1)，每年可为7至8头奶牛(400公斤活重)提供足够的能量补充。玉米秸秆(1.5 ~ 2.1 t ha - 1)可饲喂7 ~ 9头奶牛，饲喂期53 ~ 65 d。木薯叶每年可以为一到两头奶牛提供蛋白质补充。因此，玉米-木薯间作系统将有助于肯尼亚沿海地区的粮食和饲料安全，并增加收入。

To understand farmers' preference and perceptions of breed attributes, breeding and feeding practices, 419 households in western Kenya were interviewed in a cross-sectional survey. Respondents scored their preference for cattle breeds, traits and breeding methods on a scale of 1 (most preferred) to 5 (least preferred). Preferences were compared using multinomial logistic regression models on weighted scores. The Ayrshire breed was most preferred followed by the Friesian. Using hardship tolerance as a reference trait, the Friesian was preferred 4.86 times more for high milk production and Ayrshire, Jersey and Guernsey breeds 4.61, 4.60 and 4.18 times (p < 0.01) more, respectively, for milk fat content. The Ayrshire was preferred 4.16 times more for its perceived low feed requirement and 1.22 times more (p <0.01) for resistance to diseases. Friesian was the only breed preferred (3.18 times more) (p < 0.01) for high growth rate of calves. Artificial insemination (AI) was the breeding method of choice, but majority (>68%) of respondents used natural mating, because it was readily available and cheaper. The current study highlights the importance of taking into account farmers' objectives and the production environment when designing breed improvement programmes and recommends packaging of breeding together with feeding interventions.

ABSTRACT Few studies have evaluated improved pigeonpea varieties developed and released in Kenya for soil fertility improvement and contribution to the productivity of cereal-based cropping systems prevalent in marginal areas. A study comprising field and greenhouse experiments was conducted between 2009 and 2013, in order to evaluate improved pigeonpea varieties for nitrogen (N) uptake, biological nitrogen fixation (BNF), response to rhizobia inoculation and their effect on maize yields. Field experiments were conducted in Katumani Research Centre using a split-split plot design, with three pigeonpea varieties, two cropping systems and three crop residue regimes as the main plot, subplot, and sub-subplot, respectively. Greenhouse experiments were conducted at Muguga Research Centre where five pigeonpea varieties were screened for BNF and response to rhizobia inoculation in plastic pots filled with 10 kg of soil and replicated four times in a completely randomized design. Data collected on nitrogen uptake, BNF and maize and pigeonpea yields was subjected to analysis of variance using GENSTAT statistical software. Pigeonpea had significantly (p ≤ 0.05) higher nitrogen uptake compared with maize; Mbaazi II (84–114 kg N ha−1) absorbed more N, followed by Kat 60/8 (29–44 kg N ha−1) and Mbaazi I (20–37 kg N ha−1). All the three pigeonpea varieties fixed 60–70 kg N ha−1, meaning they were all good nitrogen fixers. Mbaazi II fixed significantly (p ≤ 0.05) higher N (70 kg N ha−1) compared with KAT 60/8 (66 kg N ha−1) and Mbaazi I (62 kg N ha−1) when intercropped with maize. Inoculation with rhizobia gave mixed results. Mbaazi II-maize intercrop gave the highest maize (1.9 t ha−1) and pigeonpea (1.4 t ha−1) grain yields and produced sufficient maize stover (2.1 t ha−1) and pigeonpea stalks (2.9 t ha−1).
很少有研究评估肯尼亚开发和发布的改良鸽豆品种对土壤肥力的改善和对边缘地区普遍存在的以谷物为基础的种植系统生产力的贡献。2009 - 2013年，通过大田和温室试验，评价了改良鸽豆品种对玉米氮素吸收、生物固氮、接种根瘤菌的反应及其对玉米产量的影响。在Katumani研究中心采用分块-分块设计进行田间试验，分别以3个鸽豆品种、2种种植制度和3种作物残茬制度为主、次、次样地。在Muguga研究中心进行了温室试验，筛选了5个鸽豌豆品种在装满10 kg土壤的塑料盆中接种根瘤菌的BNF和响应，并采用完全随机设计重复4次。利用GENSTAT统计软件对氮吸收、氮肥、玉米和鸽豆产量进行方差分析。鸽豆的氮素吸收量显著高于玉米(p≤0.05);Mbaazi (84 ~ 114 kg N ha−1)吸收氮量最大，其次是Kat 60/8 (29 ~ 44 kg N ha−1)和Mbaazi (20 ~ 37 kg N ha−1)。3个鸽豆品种均能固定60 ~ 70 kg N ha - 1，均为良好的固氮剂。间作玉米时，与KAT 60/8 (66 kg N ha - 1)和Mbaazi (62 kg N ha - 1)相比，Mbaazi可显著(p≤0.05)提高氮素(70 kg N ha - 1)。接种根瘤菌的结果好坏参半。Mbaazi -玉米间作玉米产量最高(1.9 t ha - 1)，鸽豆产量最高(1.4 t ha - 1)，玉米秸秆产量最高(2.1 t ha - 1)，鸽豆秸秆产量最高(2.9 t ha - 1)。

ABSTRACT Adoption studies have identified gender as one of the factors that determine technology uptake and this has been linked to women’s access to farming information or lack of it. Technology scaling up systems should utilise pathways that are compatible with the needs of rural women, who have to juggle farming with other household chores. Unfortunately, there has been limited effort to evaluate the suitability of the information pathways used to specific gender. The current study evaluates the appropriateness of field days with respect to gender of the participants. Data were collected from selected farmers who attended field days in Kenya, Uganda and Tanzania in 2014. A total of 2 615 participants were interviewed out of 6 221 who attended field days. Descriptive analysis and ordered probit and logit models were used for analysis. The majority of the participants in Kenya and Tanzania were women (51.3% and 62.6%, respectively), whereas in Uganda the majority of participants were men (57.4%). Most participants were middle aged (42 years for women and 45 years for men). The majority of the women (54.1%) had primary level education, with only 29.1% having secondary education, whereas 41% and 40.1% of men had attained primary and secondary education, respectively. The results from the econometric models shows that gender, age, education, being push-pull farmers, perceptions on Striga severity were the main significant determinants of knowledge for the ordered probit. Conversely, gender of the participant, perception on stemborers and Striga weed severity and having mobile phones were the significant determinants of willingness to adopt. The two models were significant at 1% (p < 0.001). The significance of the gender variable in the two models shows that women farmers understood more about push-pull (coefficient of ordered probit = −0.112) when trained during field days. Furthermore, the willingness to adopt push-pull after the training was much higher for women (coefficient of logit = −0.367) compared with men. The findings demonstrate that field days can be more appropriate for training farmers, especially women who are often disadvantaged in information access, as a result of their socio-economic circumstances.

Data were collected from selected farmers who attended field days in Kenya, Uganda and Tanzania in 2014. A total of 2 615 participants were interviewed out of 6 221 who attended field days. Descriptive analysis and ordered probit and logit models were used for analysis. The majority of the participants in Kenya and Tanzania were women (51.3% and 62.6%, respectively), whereas in Uganda the majority of participants were men (57.4%). Most participants were middle aged (42 years for women and 45 years for men). The majority of the women (54.1%) had primary level education, with only 29.1% having secondary education, whereas 41% and 40.1% of men had attained primary and secondary education, respectively. The results from the econometric models shows that gender, age, education, being push-pull farmers, perceptions on Striga severity were the main significant determinants of knowledge for the ordered probit. Conversely, gender of the participant, perception on stemborers and Striga weed severity and having mobile phones were the significant determinants of willingness to adopt. The two models were significant at 1% (p < 0.001). The significance of the gender variable in the two models shows that women farmers understood more about push-pull (coefficient of ordered probit = −0.112) when trained during field days. Furthermore, the willingness to adopt push-pull after the training was much higher for women (coefficient of logit = −0.367) compared with men. The findings demonstrate that field days can be more appropriate for training farmers, especially women who are often disadvantaged in information access, as a result of their socio-economic circumstances.","PeriodicalId":11421,"journal":{"name":"East African Agricultural and Forestry Journal","volume":"30 1","pages":"289 - 306"},"PeriodicalIF":0.0,"publicationDate":"2019-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87095158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT This study investigates the willingness of the respondents to establish private forest plantations (PFPs) in Oyo State, Nigeria. Two purposively selected and two randomly selected local government areas were used. One hundred and sixty household heads randomly selected were interviewed using the interview schedule and the data analysis was carried out using both descriptive (frequencies, percentages, mean) and inferential (Chi-Square and PPMC) statistics with α0.05. The majority of the respondents were male (89.2%), within 41–50 years (43.9%) and 92.8% were married. About 85.6% have knowledge of private ownership and 91.4% had knowledge on forest plantation establishment. Respondents’ attitude towards PFPs (78.4%) was favourable. A large percentage (96.4%) agreed that involvement in PFPs serves as income generating activity, whereas 58.3% identified government policy on forestry and land tenure system as major constraints to establishing PFPs. There were significant relationships between age (χ2 = 236.256), educational qualification (χ2 = 35.283), primary occupation (χ2 = 62.944) private ownership (r = 0.424), knowledge on forest plantation (r = 0.451), perception (r = 0.230), perceived benefits (r = 0.180), perceived constraints (r = −0.181) and willingness to establish PFPs. Respondents possessed high knowledge and favourable attitude towards PFPs despite the perceived constraints. The state, in collaboration with the Forestry Research Institute of Nigeria (FRIN), should initiate programmes to emphasise benefits of PFPs in order to encourage more participation and government policy on land use decree should be reviewed to promote participation in forest plantation establishment.

ABSTRACT Smallholder farmer groups increase market access and reduce transaction costs, but many challenges reduce their performance. A study on how group dynamics and capacity building influence group performance was conducted in Meru, Tharaka Nithi and Uasin Gishu Counties in 2013 with six smallholder dairy groups. Specific objectives were to determine how group dynamics influence group performance, build capacity in the groups and evaluate group performance. Focus group discussions were conducted followed by training based on findings from the discussions. Evaluation was done three months after training. Descriptive analysis was used by adopting the Institutional Analysis and Development Framework to evaluate group performance. The groups had differences in resource endowment, membership, and operating environment. After evaluation, Muchege Hortmil, Ciomburu Arithi and Langas Disabled Self-help Groups had the highest scores, whereas Kapkawa Baitany and Thuita Dairy Self-help Groups, and Chepng’oror Cooperative Society had the least. Awareness of the legal and governance systems after training increased labour division and democracy in Muchege Hortmil and Ciomburu Arithi. Strict enforcement of group rules in Muchege Hortmil improved performance, but the groups faced unfair competition from hawkers. Vulnerabilities reduced performance in Chepng’oror and Kapkawa Baitany, whereas the same vulnerabilities motivated Langas Disabled to improve. The high proportion of inactive members in Thuita reduced performance. Group performance is not so necessarily determined by the group's initial conditions, but by their efforts to organise themselves and learn. Rules are significant in determining group’s performance.

ABSTRACT The smallholder direct marketing outlets (private grain traders) serve the smallholder farmers poorly in the rural areas of Kenya, making local markets thin and less competitive. The purpose of this study is to evaluate the diversity and the determinant factors influencing the private grain traders’ performance based on the volumes transacted of green gram and pigeon pea commodities. A multistage stratified random sampling procedure was employed for this study to obtain relevant information on the grain traders in Mwala and Yatta subcounties. One hundred and ten (110) grain traders were sampled in Mwala (38) and Yatta (72) subcounties. Descriptive statistics and a multiple linear regression were used during analysis. The descriptive statistics indicated that the grain traders were diverse in terms of age with majority being 31 to 40 years old, gender in trading found mainly males (54.5%), trader education status with the majority having college education (58.2%), access to credit with large group of traders not accessing (65.5%) and the distribution of the volume purchased of green gram and pigeon peas grain, which indicated high market concentration and the trader inequality. Our model for the trader purchases of green gram and pigeon pea grain was correctly described by the multiple linear regression model. The results obtained from the ANOVA indicated that the overall regression is significant, F(16, 93) = 2 632.316, p < 0.000 for the green gram purchases and F(16, 93) = 660.542, p < 0.01 for the pigeon peas purchases. Grain markets for the green gram and pigeon pea functions poorly, because few traders dominate the markets with high shares in the volumes purchased. Few traders are likely to offer low prices to the smallholder farmers of green gram and pigeon pea. There is a possibility of collusion in the market, owing to few traders in the market.
肯尼亚农村地区的小农直销网点(私营粮食贸易商)对小农的服务很差，导致当地市场单薄，竞争力下降。本研究的目的是基于绿克和鸽豆的交易量来评估私营粮食贸易商的多样性及其影响其绩效的决定因素。本研究采用多阶段分层随机抽样方法获取姆瓦拉县和亚塔县粮食贸易商的相关信息。在Mwala(38)和Yatta(72)两个县抽样调查了110名粮食贸易商。在分析中使用描述性统计和多元线性回归。描述性统计表明，粮食贸易商的年龄分布多样化，以31 ~ 40岁居多，交易性别以男性为主(54.5%)，贸易商的学历以大专以上学历为主(58.2%)，获得信贷的贸易商居多，未获得信贷的贸易商占比较大(65.5%)，绿克和鹰口豆粮食购进量分布不均，市场集中度高，贸易商不平等。用多元线性回归模型正确地描述了商人购买绿克和鸽豆的情况。方差分析结果表明，总体回归显著，绿克采购量F(16,93) = 2 632.316, p < 0.000，鸽豆采购量F(16,93) = 660.542, p < 0.01。绿克和鸽豆的粮食市场运作不佳，因为很少有交易商在购买量中占据高份额。很少有贸易商可能向种植绿克和鸽豆的小农提供低价。由于市场上交易者少，市场上有勾结的可能。

ABSTRACT Small farmers in semi-arid areas of eastern Kenya produce green grams and pigeon peas for both subsistence and income. Because of this, it was important for a detailed investigation on the difficulty of raising marketed surplus (produce) of green grams and pigeon peas. The literature with respect to how small farmers differed in the uses of the produce and the determinants of marketed surplus is sparse. The objectives of the study therefore were to assess the differences in farm retention (for self-consumption, seed and payments in kind) and marketed surplus and to determine the factors affecting marketed surplus. Survey research design was selected for making the observations. Sampling of the households was done using a multistage technique. There were 364 households selected in two agro-ecological zones, each with 182 respondents. Data collection was done using a well-structured questionnaire. Data analysis was done using the IBM SPSS Statistics 21. One-way analysis of variance results indicated that farmers of green grams and pigeon peas differed significantly in the produce consumed, marketed and used as seed and in-kind transactions. Green grams farmers differed significantly at F(3, 1 452) = 11.420, p = 0.000, whereas pigeon peas small farmers at F(3, 1 452) = 21.680, p = 0.000. Multiple linear regression analysis results showed factors influencing farmers in marketed produce of green grams as area cultivated, yield and region of production at p = 0.01. Seeds and in-kind transactions showed positive effect at p = 0.05, whereas access to market information at p = 0.1. The factors influencing farmers on marketed production of pigeon peas were seeds and in-kind transactions and the price of output (p = 0.01). The study concluded that the design of policy interventions therefore needed to take account of small farmer variations and the factors influencing the marketed production of green grams and pigeon peas.
