Climate Information Sources, Adaptation Practices and Barriers among Smallholder Crop Farmers in Kakamega East Sub-County, Kenya
Abstract
Smallholder farmers need climate information and feasible responses within their production and financial constraints. This cross-sectional household-questionnaire study describes information sources, perceived yield trends, reported adaptation practices and barriers among 196 farmer respondents in Kakamega East, Kenya. Descriptive statistics and five exploratory cross-tabulations were recalculated from respondent-level records. Pearson chi-square statistics and Cramér’s V were calculated for each comparison; exact conditional p values were used where expected cell counts were below five. Radio was reported by 110 respondents (56.1%), personal experience by 102 (52.0%) and agricultural extension officers by 64 (32.7%). Yield trends were classified as fluctuating by 113 respondents (57.7%), decreasing by 75 (38.3%) and increasing by eight (4.1%). Reported practices included drought-tolerant varieties (165; 84.2%), adjustment of planting dates (157; 80.1%), crop diversification (137; 69.9%) and irrigation (42; 21.4%). Poverty (167; 85.2%) and high input costs (157; 80.1%) were the most frequently reported barriers. None of the five exploratory comparisons met the 0.05 significance threshold (p = 0.067–0.976; V = 0.034–0.188). Availability-based recruitment, undocumented ward-level selection and self-reported measures limit population inference. The findings support assessing accessible information and affordable, locally suitable practices; they do not establish climatic attribution, adoption determinants or practice effectiveness.
Introduction
Climate-sensitive crop production exposes smallholder farmers to uncertainty in planting, water availability and harvests. In Kenya, dependence on rain-fed production connects rainfall and temperature variability with agricultural and food-security risks (Kogo et al., 2021). The consequences depend on the farming system and the resources available to respond. Local evidence is therefore needed on the information farmers use, the practices they report and the constraints they face.
Climate change concerns persistent changes in climatic conditions, while climate variability concerns departures from those conditions across temporal scales. Adaptation involves adjustment to actual or expected climate and its effects (Intergovernmental Panel on Climate Change [IPCC], 2022). Here, climate change provides the wider policy context. The survey measures reported information sources, practices, barriers and perceived yield trends. It does not estimate meteorological trends or attribute weather events to anthropogenic climate change.
Information, reported practice and effective adaptation are different constructs. Identifying radio or an extension officer as an information source does not establish scientific knowledge, the accuracy of information received or its use in a particular farming decision. Similarly, reporting a practice does not establish when it began, why it was selected or whether it improved household outcomes. Agronomic adjustments, soil and water management, livelihood activities and cultural responses require distinct interpretation.
Kenyan research documents crop diversification as one response to climate risk, with its suitability varying across agroecological settings (Ochieng et al., 2020). In Busia County, Ndiwa et al. (2024) examined adaptation choices and intensity in relation to information, credit, off-farm income, and household characteristics. An East African review identifies substantial variation in strategies and their socioeconomic context (Ackerl et al., 2023). These studies justify practice-specific comparisons rather than treating all reported activities as a single measure of resilience.
Earlier Kakamega research described adaptation options and constraints on their implementation (Mulinya, 2017). The present study adds a respondent-level description for the area designated Kakamega East. It contributes an account of information channels, practice prevalence and perceived barriers, along with five exploratory comparisons based on paired responses. The analysis is restricted to surveyed farmers and does not establish representativeness across the sub-county.
Four objectives guide this article: (1) describe reported climate information sources and perceived crop-yield trends; (2) describe reported adaptation practices and related livelihood responses; (3) examine exploratory bivariate associations between selected farmer characteristics and reported practices; and (4) identify reported economic, production, market, water and input-quality barriers. Direct climate-awareness prevalence or rainfall or temperature perceptions.
Materials and Methods
Study setting
The study covered six wards in Kakamega County, western Kenya: Isukha North, Isukha East, Isukha South, Isukha West, Isukha Central and Murhanda. The survey used the designation Kakamega East; county administrative records list these wards under Shinyalu (County Government of Kakamega, 2015, 2023). Crop production included maize, beans, vegetables and sugarcane, with livestock and non-farm work also supporting household livelihoods. Rain-fed production makes rainfall timing relevant to planting decisions, while limited cultivated area can constrain diversification and water-management investment.
Study design and population
The study used a quantitative, cross-sectional household questionnaire survey. Ward coverage and availability-based home interviews are treated as non-probability recruitment because random selection within wards was not documented. Eligible participants were smallholder crop farmers aged 18 years or older who had lived in the sub-county for at least ten years and farmed full- or part-time. We targeted household heads as respondents and mainly interviewed them. The respondent farmer was the unit of analysis; household size, cultivated area and livelihood activities described the household farming context. The reported achieved sample was 196 farmer respondents.
Sample size and sampling procedure
Sample size and retrospective numerical reference
The reported survey sample comprised 196 farmer respondents. The 2009 Kenya Population and Housing Census recorded 159,475 residents in Shinyalu, as reported in the Statistical Abstract 2010 (Kenya National Bureau of Statistics [KNBS], 2010) and the county profile (County Government of Kakamega, 2015). This resident count provides geographical context; it is not an eligibility-checked frame of farming households. For a retrospective numerical reference, the finite-population expression of Krejcie and Morgan (1970) is evaluated at 95% confidence, an assumed proportion of 0.50 and nominal precision of seven percentage points:
In this expression, n is the numerical reference sample size; N = 159,475 is the resident population used for the calculation; χ² = 3.841 is the critical chi-square value for one degree of freedom at 95% confidence; p = 0.50 is the conservative assumed population proportion; and d = 0.07 is the nominal absolute precision of seven percentage points. Thus, 1 − p = 0.50 and d² = 0.0049. Substitution gives:
The numerical result rounds upward to 196. This retrospective calculation shows the nominal precision assumption associated with a reference sample of this size; it does not document the sample-size decision made before fieldwork. A population margin of error cannot be assigned to the completed survey because an eligible household frame and probability selection were not established. The calculation is not a power analysis for the individual association tests.
Recruitment and reported survey sample
The survey findings describe 196 farmer respondents. Recruitment and field disposition records are required to establish the numbers selected, contacted, refusing, excluded or providing incomplete questionnaires. The reported sample total does not establish the valid denominator for every item, and no response rate is calculated from the total alone. Conclusions are restricted to the surveyed respondents.
Ward sampling frame and allocation
The six wards defined the geographical coverage. Table 1 gives their historical resident populations and a computed proportionate reference allocation for the reported sample of 196. The ward schedule uses the 2009 KNBS census and totals 159,475 (Independent Electoral and Boundaries Commission [IEBC], 2012, Schedule, wards 1041–1046). The eligible farming-household frame, the actual numbers selected, and the completed interviews by ward require the household and field registers.
Where a complete, eligibility-checked household list is available, proportionate stratified sampling can allocate a sample of 196 across wards. Each household must appear in one stratum only. Let Nₕ be the eligible frame in ward h, NF the sum of all ward frames, pₕ the ward’s proportion, and qₕ its unrounded quota for n = 196, provided NF is at least 196. NF refers to eligible households, not the resident population of 159,475. This conditional procedure does not establish the design used in the completed survey.
Reference integer allocations nₕ should total 196. One transparent rule is to take the floor of each quota qₕ, then assign the remaining places to the wards with the largest fractional remainders; ties require a documented rule. Actual completed interviews by ward must be taken from the field records; calculated quotas do not establish those counts.
For the population-based reference calculation in Table 1, Pₕ is the resident population of ward h, wₕ is its share of the six-ward total and tₕ is its unrounded quota for 196. The integer allocation aₕ applies the largest-remainder rule to tₕ. This calculation assumes that eligible farming households are distributed in proportion to residents; the household frame is needed to assess that assumption. It provides a coverage benchmark rather than a record of implemented selection. The weights and quotas are:
| Stratum / ward | Resident population 2009 Pₕ | Population proportion wₕ | Calculated allocation aₕ |
|---|---|---|---|
| Isukha North | 23,496 | 0.1473 | 29 |
| Isukha East | 17,930 | 0.1124 | 22 |
| Isukha South | 35,807 | 0.2245 | 44 |
| Isukha West | 19,412 | 0.1217 | 24 |
| Isukha Central | 34,545 | 0.2166 | 42 |
| Murhanda | 28,285 | 0.1774 | 35 |
| Total | 159,475 | 1.0000 | 196 |
Source. KNBS (2010), 2009 census; IEBC (2012), Schedule, wards 1041–1046. Population shares are rounded to four decimal places. Calculated allocations use unrounded shares and largest-remainder rounding to total 196. They assume that eligible farming households are distributed in proportion to residents.
Recorded household recruitment
We administered questionnaires one-to-one at farmers’ homes based on respondent availability. The available account does not document the household list, random draw, interval, random start or treatment of unavailable households. It therefore supports the non-probability interpretation used in this article. If the field records establish simple random sampling or another design, the Methods should report that actual procedure.
Selection procedure with a complete frame
If the field records confirm systematic random selection within strata, the procedure should identify the list and the following steps. These steps describe an appropriate probability procedure; they do not establish that it was used in the completed survey.
The researchers first checked eligibility, removed duplicate households and numbered the complete ward list from 1 to Nₕ. Check that its order does not create periodic patterns related to the outcomes. For each ward with a positive allocation nₕ, divide its eligible frame by its allocated sample:
When kₕ is an integer, draw an independent random start rₕ from 1 through kₕ, then select positions rₕ, rₕ + kₕ, rₕ + 2kₕ and so on until nₕ households have been selected (Statistics Canada, 2021). For a non-integer interval, retain kₕ and use fractional systematic selection: draw uₕ uniformly with 0 < uₕ ≤ kₕ and take the ceiling of uₕ + j kₕ for j = 0, …, nₕ − 1. Record the start, interval and selected household identifiers.
Lastly, record completed and partial interviews, refusals, noncontacts, ineligible cases and unknown eligibility. Retain nonresponding households in the field records and report any replacement rule. When eligibility is known for all selected cases, the completed-interview response rate is 100 × completed interviews ÷ all eligible selected households, including refusals and noncontacts. Unknown eligibility requires a stated outcome-rate definition (American Association for Public Opinion Research [AAPOR], 2023).
The allocation table, household list, selection records and field dispositions must agree. A preferred procedure must not be retrofitted to data already collected under a different design.
Questionnaire administration and quality control
We administered the structured questionnaire face-to-face at respondents’ homes. Farmers self-reported responses during a one-to-one interview; this was an interviewer-administered questionnaire rather than a form completed independently by participants. The instrument covered respondent and household characteristics, cultivated land and crop types, climate awareness and perceived changes, information sources, reported adaptation practices, alternative livelihoods, and barriers to adaptation.
The reported variables included numeric information such as age and household size; categorical information such as sex, education and land-size bands; awareness indicators; and information sources, crops, practices and constraints. Several reported items include more than one source or practice per farmer. These options are summarised individually rather than treated as mutually exclusive shares of a total. Reported temperature changes referred to the preceding decade, whereas the crop-yield question used a twenty-year reference period. These recalled experiences were not treated as measured climatic trends or independently verified yield records.
The questionnaire was pre-tested among ten small-scale farmers with similar characteristics in a neighbouring sub-county. The pre-test assessed comprehension and question flow, and the instrument was revised in response to participants’ feedback. Quantitative responses were entered into Microsoft Excel, cleaned and analysed in SPSS version 22.0.
Variables and operational definitions
Awareness, perceived climatic changes, individual reported practices, and barriers are distinct survey outcomes. The planned comparisons pair education with drought-tolerant varieties and organic farming, age with non-farm activities and crop diversification, and cultivated area with irrigation. Each practice is considered separately; no composite adoption score is created. Table 2 aligns the four objectives with the available descriptive evidence and the illustrative analysis. The original questionnaire, response coding and missing-value codes still require verification.
| Objective and construct | Indicator or variable | Measurement and analytical role | Summary or procedure |
|---|---|---|---|
| Objective 1 Characterise climate change awareness and perceived changes in rainfall and temperature | Awareness; rainfall timing; temperature changes | Respondent-reported awareness and perceptions; descriptive outcomes | Reported percentages; valid item denominators require verification |
| Objective 2 Describe reported adaptation practices and livelihood responses | Varieties; planting dates; diversification; irrigation; soil practices; livelihoods | Separate reported responses; selections can overlap | Reported practice percentages and response typology |
| Objective 3 Explore bivariate associations between selected farmer characteristics and reported practices | Education; age group; cultivated area; practice-specific Yes or No | Planned empirical comparisons; illustrative reporting format | Crosstabs; Pearson χ²; df; N; p; Cramér’s V; expected-frequency checks |
| Objective 4 Identify reported economic, production and institutional barriers | Poverty; inputs; pests; markets; water; seed quality | Separate respondent-reported constraints | Reported constraint percentages; selections can overlap |
| Household context | Household size; crops; livestock; non-farm activities | Descriptive farming and livelihood context | Mean and SD for numeric items; percentages for categories |
Note. Awareness represents self-reported recognition, not a validated knowledge score. Climatic indicators are perceptions. Practices may overlap. Objective 3 uses an illustrative reporting format.
Age is recorded in years and household size in members. Education categories are no formal education, primary, secondary and tertiary. The supplied age groups are 22–39, 40–59 and 60–91 years; these labels were checked against every recorded age and matched in all 196 records. Land under crop production is recorded as less than one acre, one acre, two acres or three acres. These categories were retained without combining sparse groups after inspection of test results. Land owned and cultivated area are different measures.
Perceived yield trend has three recorded categories: fluctuating, decreasing and increasing. It is a subjective assessment rather than measured harvest output. Each practice and barrier is analysed as its own binary indicator. No composite adaptation index is constructed. The irrigation indicator appears in both the production-system and practice fields; their responses agree in all 196 records, so irrigation is counted once in each relevant table. The file has no direct awareness indicator, rainfall- or temperature-perception responses, ward identifier or interview date.
Data preparation and descriptive analysis
The respondent-level Data worksheet was used as the analytical source. Counts and statistics were recomputed rather than taken from the workbook’s existing summary formulas. Checks covered unique identifiers, duplicate records, blank entries, permitted category labels, age-group consistency and agreement between irrigation fields. There were 196 unique identifiers, no duplicate records across the 37 non-identifier fields and no blank or invalid entries in the analysed variables. Thus, each displayed descriptive item, and each paired comparison has valid N = 196 and zero missing values in the analytical file. The absence of blanks in this file does not establish how unanswered questions were coded during field entry.
Numeric variables are summarised using the mean, sample standard deviation and range. Categorical results report observed counts and percentages calculated as 100 × count ÷ valid item N. Percentages are rounded to one decimal place from unrounded values, with ties rounded up. Multiple-response percentages may sum above 100%; mutually exclusive percentages may differ slightly from 100% because of rounding. No missing values were imputed, no respondent rows were reconstructed, and no record values were altered.
Analytical Model
Five comparisons were specified: education with drought-tolerant varieties; education with organic farming; age group with non-farm activities; age group with crop diversification; and cultivated area with irrigation. The comparisons use each respondent’s recorded characteristic and practice response. Cross-tabulation cells show counts and row percentages, with both Yes and No responses and the row total. The tests assume independence of respondents and mutually exclusive categories within each comparison.
Let Oᵢⱼ and Eᵢⱼ denote observed and expected counts in a table with r rows and c columns. Expected counts use row totals Rᵢ, column totals Cⱼ, and valid N. Pearson’s statistic is uncorrected, with nominal df = (r − 1)(c − 1); Cramér’s V summarises association (SciPy community, n.d.-a, n.d.-b):
Asymptotic Pearson p-values were used when every expected frequency was at least five. Where an expected frequency was below five, an exact conditional Pearson test enumerated every feasible table with the observed row and column totals. For an r × 2 table, let a be a feasible count vector for one column and K its fixed total. The conditional probability of a is the product of the row-specific binomial coefficients divided by the overall binomial coefficient. The p-value sums the probabilities of all tables whose Pearson statistic is at least as large as the observed statistic, including ties. This uses the fixed-margin null distribution (SciPy community, n.d.-c) and does not alter the respondent records.
Here, the entries of a sum to K, with each entry between zero and its corresponding row total. The binomial coefficient counts the combinations of selecting that column’s responses within each row. Pearson-tail ordering is used rather than ordering tables by their individual probability.
Exact enumeration covered 5,309 feasible tables for education with drought-tolerant varieties, 12,749 for education with organic farming and 1,555 for cultivated area with irrigation. Conditional probabilities summed exactly to one using integer combinatorial weights. Expected frequencies, Pearson statistics and Cramér’s V were also checked independently using direct arithmetic and SciPy 1.17.0 with NumPy 2.3.5. The five p-values are exploratory and unadjusted for multiple comparisons; 0.05 is the reporting threshold. No regression, causal interpretation or population-level precision claim is attached to these comparisons.
Results
Respondent and farming characteristics
The analysis included 196 farmer respondents. Mean age was 49.4 years (SD 13.7; range 22–91), and mean household size was 6.8 members (SD 3.1; range 1–19). Female respondents numbered 103 (52.6%) and male respondents 93 (47.4%). Of the respondents, 150 (76.5%) cultivated less than one acre, 195 (99.5%) reported predominantly rain-fed production, and 42 (21.4%) reported irrigation (Table 1).
| Characteristic | Category or measure | n (%) or summary |
|---|---|---|
| Age in years | Mean (SD); range | 49.4 (13.7); 22–91 |
| Household size in members | Mean (SD); range | 6.8 (3.1); 1–19 |
| Sex | Female | 103 (52.6) |
| Sex | Male | 93 (47.4) |
| Age group | 22 to 39 years | 49 (25.0) |
| Age group | 40 to 59 years | 98 (50.0) |
| Age group | 60 to 91 years | 49 (25.0) |
| Education | No formal education | 18 (9.2) |
| Education | Primary | 80 (40.8) |
| Education | Secondary | 77 (39.3) |
| Education | Tertiary | 21 (10.7) |
| Farming experience | 1 to 5 years | 24 (12.2) |
| Farming experience | 6 to 10 years | 38 (19.4) |
| Farming experience | 11 to 15 years | 42 (21.4) |
| Farming experience | 16 to 20 years | 39 (19.9) |
| Farming experience | More than 20 years | 53 (27.0) |
| Land owned | Less than 1 acre | 98 (50.0) |
| Land owned | 1 acre | 56 (28.6) |
| Land owned | 2 acres | 23 (11.7) |
| Land owned | 3 acres | 19 (9.7) |
| Cultivated area | Less than 1 acre | 150 (76.5) |
| Cultivated area | 1 acre | 34 (17.3) |
| Cultivated area | 2 acres | 8 (4.1) |
| Cultivated area | 3 acres | 4 (2.0) |
| Production system | Predominantly rain-fed, Yes | 195 (99.5) |
| Reported irrigation, Yes | 42 (21.4) |
Note. Valid N = 196 for every variable; missing entries in the analytical file = 0. SD is the sample standard deviation. Rain-fed production and irrigation are separate indicators and can coexist. Land owned and land cultivated are distinct. One acre is approximately 0.405 hectares.
Information sources and perceived yield trends
Radio and personal experience were the most frequently recorded information sources (Table 2). Agricultural extension officers were reported by 64 respondents (32.7%). These responses identify information channels; they do not measure information quality, frequency of extension contact or a validated level of climate awareness. Fifteen respondents recorded No for all seven listed sources. This describes their coded responses and does not establish lack of access to every possible source.
| Information source | Yes n | Valid N | Missing n | Yes % |
|---|---|---|---|---|
| Radio | 110 | 196 | 0 | 56.1 |
| Personal experience | 102 | 196 | 0 | 52.0 |
| Agricultural extension officers | 64 | 196 | 0 | 32.7 |
| Seminars | 34 | 196 | 0 | 17.3 |
| Television | 30 | 196 | 0 | 15.3 |
| School | 21 | 196 | 0 | 10.7 |
| Public barazas | 8 | 196 | 0 | 4.1 |
Note. Multiple sources can be reported by the same respondent. Each percentage uses its own complete Yes or No item with N = 196. A baraza is a public community meeting.
Yield trends were described as fluctuating by 113 respondents (57.7%), decreasing by 75 (38.3%) and increasing by eight (4.1%). These three categories classify all 196 records (Table 3). The results concern perceived direction or variability of yields and provide no numerical estimate of harvest change or its cause.
| Perceived trend | n | Valid N | Missing n | % |
|---|---|---|---|---|
| Fluctuating | 113 | 196 | 0 | 57.7 |
| Decreasing | 75 | 196 | 0 | 38.3 |
| Increasing | 8 | 196 | 0 | 4.1 |
| Total | 196 | 196 | 0 | 100.0 |
Note. These are mutually exclusive recorded categories. The three displayed category percentages sum to 100.1% because each is rounded independently; their unrounded sum is 100%. No residual category or missing-response percentage is inferred.
Reported adaptation practices and related responses
The most frequently reported agronomic practice was using drought-tolerant varieties (165; 84.2%), followed by adjusting planting dates (157; 80.1%) and crop diversification (137; 69.9%). Irrigation was reported by 42 respondents (21.4%) and mulching by 39 (19.9%). Indigenous chicken rearing (172; 87.8%) and non-farm activities (148; 75.5%) were common related livelihood activities. Table 4 separates these responses by broad function and does not treat their reported presence as evidence of effectiveness or a climate-specific reason for uptake.
| Response domain | Practice or response | Yes n | Yes % |
|---|---|---|---|
| Agronomic | Drought-tolerant varieties | 165 | 84.2 |
| Adjustment of planting dates | 157 | 80.1 | |
| Crop diversification | 137 | 69.9 | |
| Changing crop types | 29 | 14.8 | |
| Soil and moisture | Reduced chemical use | 147 | 75.0 |
| Organic farming | 49 | 25.0 | |
| Mulching | 39 | 19.9 | |
| Water management | Irrigation | 42 | 21.4 |
| Livelihood | Indigenous chicken rearing | 172 | 87.8 |
| Non-farm activities | 148 | 75.5 | |
| Farming location | Relocation for farming | 20 | 10.2 |
| Cultural or religious | Prayers for rain | 16 | 8.2 |
Note. Valid N = 196 and missing entries = 0 for every practice item. Responses can overlap. Livelihood and cultural responses are listed separately from crop, soil and water practices. Indigenous chicken rearing does not measure all livestock keeping. The irrigation practice and production-system fields agree for every respondent.
Bivariate associations between selected farmer characteristics and reported practices
We cross-tabulated education with drought-tolerant varieties and organic farming. Neither exact conditional comparison met the 0.05 threshold (Table 5).
| Education level | Drought-tolerant varieties Yes n (%) | Drought-tolerant varieties No n (%) | Organic farming Yes n (%) | Organic farming No n (%) | Total n |
|---|---|---|---|---|---|
| No formal education | 17 (94.4) | 1 (5.6) | 2 (11.1) | 16 (88.9) | 18 |
| Primary | 66 (82.5) | 14 (17.5) | 23 (28.8) | 57 (71.3) | 80 |
| Secondary | 61 (79.2) | 16 (20.8) | 17 (22.1) | 60 (77.9) | 77 |
| Tertiary | 21 (100.0) | 0 (0.0) | 7 (33.3) | 14 (66.7) | 21 |
| Total | 165 (84.2) | 31 (15.8) | 49 (25.0) | 147 (75.0) | 196 |
Note. Row percentages; total-row percentages use N = 196. Both comparisons: valid N = 196, excluded n = 0; V = Cramér’s V. Drought-tolerant varieties: χ²(3) = 6.963, exact p = 0.06706, V = 0.188; minimum expected 2.847, 2/8 cells (25.0%) below five. Organic farming: χ²(3) = 3.580, exact p = 0.31432, V = 0.135; minimum expected 4.500, 1/8 cells (12.5%) below five. Neither table has an expected count below one.
Non-farm activities were reported by 32 of 49 respondents aged 22–39 (65.3%), 77 of 98 aged 40–59 (78.6%) and 39 of 49 aged 60–91 (79.6%). Crop diversification was reported by 38 of 49 (77.6%), 64 of 98 (65.3%) and 35 of 49 (71.4%), respectively. Irrigation was reported by 31 of 150 farmers cultivating less than one acre (20.7%), eight of 34 cultivating one acre (23.5%), two of eight cultivating two acres (25.0%) and one of four cultivating three acres (25.0%). The small two- and three-acre groups require cautious interpretation (Table 6).

Panel A Age group and reported livelihood or crop practices
| Age group | Non-farm Yes n (%) | Non-farm No n (%) | Diversification Yes n (%) | Diversification No n (%) | Total n |
|---|---|---|---|---|---|
| 22–39 years | 32 (65.3) | 17 (34.7) | 38 (77.6) | 11 (22.4) | 49 |
| 40–59 years | 77 (78.6) | 21 (21.4) | 64 (65.3) | 34 (34.7) | 98 |
| 60–91 years | 39 (79.6) | 10 (20.4) | 35 (71.4) | 14 (28.6) | 49 |
| Total | 148 (75.5) | 48 (24.5) | 137 (69.9) | 59 (30.1) | 196 |
Panel A tests. Non-farm activities: χ²(2) = 3.697, asymptotic p = 0.15747, V = 0.137; minimum expected count 12.000, 0/6 cells below five. Crop diversification: χ²(2) = 2.401, asymptotic p = 0.30110, V = 0.111; minimum expected count 14.750, 0/6 cells below five.
Panel B: Cultivated area and irrigation
| Cultivated area | Irrigation Yes n (%) | Irrigation No n (%) | Total n |
|---|---|---|---|
| Less than 1 acre | 31 (20.7) | 119 (79.3) | 150 |
| 1 acre | 8 (23.5) | 26 (76.5) | 34 |
| 2 acres | 2 (25.0) | 6 (75.0) | 8 |
| 3 acres | 1 (25.0) | 3 (75.0) | 4 |
| Total | 42 (21.4) | 154 (78.6) | 196 |
Panel B test. Irrigation: χ²(3) = 0.232, exact p = 0.97614, V = 0.034; minimum expected count 0.857, 3/8 cells (37.5%) below five and 1/8 (12.5%) below one. Each comparison in Table 6 has valid N = 196 and zero excluded records. Cell percentages use row totals; total-row percentages use 196. V denotes Cramér’s V; df are nominal Pearson degrees of freedom.
Across the five comparisons, p values ranged from 0.06706 to 0.97614 and Cramér’s V from 0.034 to 0.188. None met the stated 0.05 threshold. This indicates insufficient statistical evidence against independence in these comparisons; it does not establish equivalence between groups or rule out relationships that a larger or differently recruited sample could identify.
Reported barriers
Poverty was reported by 167 respondents (85.2%) and high input costs by 157 (80.1%). Other commonly recorded barriers were pests and diseases (137; 69.9%), poor agricultural practices (127; 64.8%) and limited market access (118; 60.2%). Lack of water for irrigation was reported by 98 respondents (50.0%) and low-quality seeds by 88 (44.9%) (Table 7). These are respondent-reported constraints; no independent poverty threshold, agronomic assessment or seed-quality test was applied.

Discussion
Information channels and perceived yields
Radio and personal experience were prominent information sources, while about one-third of respondents identified agricultural extension officers. This supports considering both broadcast communication and farmer-service contact when assessing local information provision. Research in Gilgil distinguished media, interpersonal contacts and extension pathways (Waaswa et al., 2021), while evidence from northern Ghana shows that source use and information utilisation vary across farming contexts (Alhassan et al., 2025). These comparisons provide context; the present source indicators do not measure utilisation intensity or communication effectiveness.
Information-source reporting should not be treated as direct climate awareness. A farmer may name a source without understanding a forecast, and a farmer who does not select a listed channel may use another source. The analysis therefore does not reproduce an awareness prevalence estimate. Future measurement should distinguish source access, understanding, trust and use in a farming decision, with the survey instrument and coding documented.
Most respondents perceived yields as fluctuating or decreasing. This is evidence about reported production experience, not an estimate of long-term yield change. Independent harvest records and relevant meteorological observations would be needed to assess the relationship between weather and production. Research comparing farmer perceptions with measured rainfall and temperature demonstrates why these evidence streams should be examined separately (File & Nhamo, 2024). The present study cannot attribute perceived yield trends to climate rather than soil, pests, inputs or other conditions.
Reported practices and livelihood responses
Drought-tolerant varieties, planting-date adjustment, and crop diversification were reported more often than mulching. These options have different resource requirements, and a high reporting frequency should not be interpreted as proof of suitability or effectiveness. Research in Busia identifies financial and informational considerations in adaptation choices (Ndiwa et al., 2024). The present data show which options were recorded but do not identify the reason an individual farmer used or did not use them.
Diversification was reported by 69.9% of respondents, most of whom cultivated small areas. Diversification may spread production risks, but its performance depends on the crops, land allocation and agroecological context. Kenyan panel research cautions against applying diversification uniformly across settings (Ochieng et al., 2020). Crop-specific portfolios and their effects on output, costs and food availability were not measured here.
Reduced chemical use and organic farming were recorded as different practice indicators. Lower chemical use may reflect management preference, cost or product availability and cannot automatically be interpreted as improved soil quality. Similarly, the drought-tolerance label was self-reported and was not verified through seed characteristics or field performance. Indigenous chicken rearing and non-farm work describe livelihood activities; their timing and climate-specific motivation were not measured. Prayer is retained as a cultural response and is interpreted separately from biophysical changes to crop, soil and water management.
Interpretation of the exploratory comparisons
The five cross-tabulations show differences in observed reporting proportions but no comparison met the 0.05 threshold. The education comparison for drought-tolerant varieties had the largest observed association (V = 0.188; exact p = 0.06706). This should not be described as a confirmed educational gradient: all tertiary-educated respondents reported the practice, but the proportions did not rise consistently across every education category, and the small groups produced sparse expected cells.
The age and cultivated-area comparisons likewise do not demonstrate that these characteristics are irrelevant to practice choice. Broad age categories can conceal variation within groups, and the cultivated-area distribution is highly concentrated below one acre. Only eight and four respondents were in the two- and three-acre categories. Exact testing addresses the reference distribution for sparse cells; it does not increase information in small groups or correct selection bias.
Regional reviews and the Busia study examine socioeconomic circumstances alongside adaptation choices (Ackerl et al., 2023; Ndiwa et al., 2024). Their measures, sampling and models differ from these bivariate comparisons. A non-significant unadjusted test in this sample cannot overturn those findings or establish a causal explanation. Joint modelling would require adequately measured candidate variables, sufficient information for each outcome and a defensible recruitment account.
Barriers and implications for support
Poverty and high input costs were the most frequently reported barriers. These findings identify affordability as a concern for the surveyed respondents, consistent with earlier Kakamega work describing financial constraints (Mulinya, 2017). They do not measure poverty using income or expenditure thresholds or estimate how much uptake would change if input prices fell.
Production, market, water, and seed-quality concerns indicate that support may need to go beyond information provision. Half the respondents reported lack of irrigation water, but the file does not identify water sources, seasonal reliability, infrastructure costs or environmental limits. Technical and financial feasibility must therefore be assessed before recommending a particular water investment. Likewise, reported seed-quality and market problems require direct assessment before judging an intervention effective.
County agricultural and meteorological services could assess how radio messages, extension contact and community meetings provide farmers with useful, understandable information. Such an assessment should measure comprehension and use in planting or management decisions, including whether different educational backgrounds are reached. Source prevalence alone cannot identify the best communication format.
Agricultural services, researchers and farmer groups could evaluate affordable seed, crop-diversification and soil-management options suited to small cultivated plots. Variety advice should distinguish drought tolerance from early maturity and assess local performance. Poverty and input-cost reports justify assessing affordability, while evidence of effectiveness should come from monitored outcomes rather than practice counts alone.
Supplementary irrigation or water harvesting should be assessed where water availability, costs and environmental conditions allow. Reported market and seed-quality concerns also support investigating collective marketing arrangements and reliable input access. These proposals are linked to recorded concerns; their benefits were not tested in this survey.
Limitations
The cross-sectional design cannot establish temporal ordering, causal effects or practice effectiveness. Information sources, practices, barriers and yield trends are self-reported and may be affected by recall or social-desirability bias. No meteorological series, measured harvests, income records or objective input-quality measures were analysed.
Availability-based recruitment and undocumented within-ward selection restrict inference to the surveyed respondents. Actual ward counts and clustering could not be evaluated because the analytical file lacks ward identifiers. The tests assume independent respondent records, an assumption that the available recruitment information cannot establish fully. The reported target of 384, the reasons for the achieved sample of 196 and field response dispositions remain undocumented. Model-based exploratory p-values do not provide design-based population inference or a population margin of error.
Conclusion
Among the 196 surveyed farmers, radio and personal experience were the leading recorded climate information sources, and perceived yields mostly fluctuated or decreased. Drought-tolerant varieties, adjustment of planting dates and crop diversification were frequently reported, while irrigation was less common. None of the five exploratory comparisons provided statistically significant evidence against independence at the 0.05 threshold. Poverty and high input costs were the most frequently reported barriers. These findings support assessing accessible information and affordable, locally suitable practices for the surveyed farming context. They do not establish sub-county prevalence, adoption determinants, climatic attribution or improved outcomes from the reported practices.
