Competences of agricultural extension agents in dissemination of climate change adaptation strategies in Misungwi district, Tanzania
(Asian Journal of Agricultural Extension, Economics & Sociology, 2025-03-28) Samweli, Sagire Nelson; Martin, R.; Ntumva, M.
This paper assessed the awareness and competencies of extension agents regarding climate change in Tanzania, utilizing questionnaires from 64 agents and analysing data through descriptive statistics. Results indicated a high knowledge level, with an overall mean score of 6.36; 70.3% identified drought and extreme weather as significant climate change effects, and 82.8% recognized soil conservation as vital for adaptation. However, knowledge gaps were noted in crop diversification (53.1%) and climate-resilient crop varieties (46.9%). Skills assessment yielded a mean score of 6.8, with 70.3% competent in recommending mulching and drip irrigation, and 75.0% guiding farmers in organic farming. Attitudes towards climate adaptation were generally positive, with a mean score of 3.97; 73.5% valued continuous learning. Yet, practice inconsistencies emerged, as only 23.4% frequently recommended climate-resilient practices and 37.5% regularly implemented innovative solutions. Institutional support was inadequate, with the highest support observed in policy availability (54.7%), while the lowest was in digital tool provision, as none of the extension agents (100%) had access to such resources. The findings suggest that enhanced training, improved communication, and better resource allocation are essential for strengthening extension agents' roles in aiding farmers' climate change adaptation in Tanzania.
Extension advisory services on farmer’s climate change mitigation strategies in Misungwi district, Tanzania: issues and options
(International Journal of Environment and Climate Change, 2025-02-17) Samweli, Sagire Nelson; Martin, R.; Ntumva, M.
This study evaluates the impact of extension advisory services on farmers’ climate change mitigation strategies. Questionnaires were completed by 64 extension agents and data were analysed using descriptive statistics. The study found that the most common method used for identifying farmers’ climate change adaptation needs is extension agents visiting farmers (84.6%), followed by training sessions are less frequently used (26.2%), and other methods are rarely employed (1.5%). Insufficient training on climate change, with a frequency of 55, resource constraints, reported by around 49 respondents and limited access to climate information also stand out as a significant issue, with a frequency of about 41, and lastly knowledge barriers with 39 respondents were shown as the challenges encountered during dissemination of advisory services to farmers. This study revealed that majority (56.9%) of extension agents reported receiving transport facilities, while 41.5% had access to timely updated information. Though, only 18.5% of respondents indicated receiving regular training. This study concludes that the majority of extension agents have reported that they do not receive sufficient support in their efforts to educate farmers on how to adapt to climate change. The extension agents are not prepared to deal with the complexities of climate change, despite the fact that they rely on personal visits to capture the needs of the farmers. The low level of diversity engagement approaches, the low rates of hands-on training, and the moderate perceptions of comfort in communicating climate information are all indicators that this is the case. In addition, many extension agents believe that the increase of these concerns is caused by resource problems, which include inadequate access to timely information, inadequate training, and inadequate financial resources. This study recommends that the government should allocate enough resources aimed at supporting the extension agents in fulfilling their operations.
Factors influencing the adoption of improved groundnut cultivars amongst smallholder farmers in Singida Tanzania
(AJOL, 2023) Humphrey, S. C.; Martin, R.; Ntumva, M.
Groundnut is amongst the global important food and cash crops; irrespective of its importance, studies report its low adoption. Amongst the reported adoption factors were age, gender, education, group membership and seed availability. Nevertheless, there is insufficient documentation on the influence of these factors on the adoption of groundnut amongst beneficiaries of Singida Rural Farmer Research Networks (FRNs). Innovation systems, networks and Roger’s theories of diffusion of innovations guided this study to establish the determinants of the adoption of improved groundnut cultivars amongst these target groups. Specifically, the study (1) assessed the adoption of improved groundnuts in relation to farmers’ socio-economic characteristics; (2) determined the factors that influenced the adoption of improved groundnuts and (3) examined farmers’ adoption perception towards access to services, technological characteristics and the institutional environment. Cross-sectional design and mixed research methods were used. The socioeconomic characteristics of farmers were compared using Chi-square test cross-tabulations. The binary logistic regression model was used to determine factors influencing the adoption of improved groundnut cultivars. A Likert scale was used to assess the farmers’ perceptions towards the adoption of improved groundnut cultivars in relation to access to services, technological characteristics and the institutional environment. Findings show that socioeconomic characteristics such as age, sex, marital status, education level and income had no significant influence on the adoption of improved groundnuts. The adoption of improved groundnuts was significantly influenced by three factors: FRN group membership, seed accessibility and technological characteristics which include adaptive to agroecological zones, high yields, early maturity, drought tolerance, pests and disease resistance. The majority of farmers had a positive perception towards access to services, technological characteristics and the institutional environment for the adoption of improved groundnut cultivars. In this regard, sensitization for more farmers to join groups and enhancement of timely seed availability and accessibility of improved groundnut cultivars are recommended.
