Abstract and Figures

Gender gaps in crop productivity can negatively affect rural socio-economic development of agrarian economies with serious implications for food and nutrition security. We assess productivity in male- and female-managed sorghum plots in Lira, Kumi, and Serere districts in Uganda. We find male-managed plots have higher productivity of 850.6 kgs/ha compared to female-managed plots (832.6 kgs/ha). An observed mean gender gap of 18% due to structural advantages of male plots (57%), structural disadvantages of female plots (33%), and endowment (10%) exists. Therefore, interventions aimed at promoting equitable access to institutional support services are paramount in reducing structural disadvantages against female farmers.

ABSTRACT
Gender gaps in crop productivity can negatively aect rural socio-
economic development of agrarian economies with serious implications
for food and nutrition security. We assess productivity in male- and
female-managed sorghum plots in Lira, Kumi, and Serere districts in
Uganda. We nd male-managed plots have higher productivity of 850.6
kgs/ha compared to female-managed plots (832.6 kgs/ha). An observed
mean gender gap of 18% due to structural advantages of male plots
(57%), structural disadvantages of female plots (33%), and endowment
(10%) exists. Therefore, interventions aimed at promoting equitable
access to institutional support services are paramount in reducing
structural disadvantages against female farmers.

1. Introduction
Agricultural productivity plays an important role in promoting welfare and stimulating growth in on-
farm and non-farm activities of rural households. Specically, sorghum (Sorghum bicolor) contributes
approximately half of the micronutrient requirements of small-holder farmers living within the semi-
arid tropics of Africa and Asia; it is therefore a key crop in promoting food and nutrition security
(Kumar et al. 2018). Sorghum is a drought-tolerant cereal crop that is mainly grown in the semi-
arid tropics. In Africa, it is the second staple grain crop after maize (Mundia et al. 2019) and is
mainly cultivated for food and fodder, especially by smallholder farmers in drylands that are charac-
terised by low soil fertility, inadequate extension services, and erratic rainfall (Assefa et al. 2020).
In Uganda, sorghum is an important dryland cereal after maize and wheat in terms of total pro-
duction (Wang et al. 2015). Uganda supplies approximately 0.5% of the worlds sorghum output
(USDA 2018). It is the staple crop for a majority of people in the Northern and Eastern parts
where it is primarily grown. Farmers in these areas exhibit low levels of input use; hence, productivity
over the years has remained relatively low and the sorghum value chain greatly remains under-
developed (Nangobi and Mugonola 2018; Tenywa et al. 2018).
Various studies have documented the existence of gender disparities in agricultural production in
sub-Saharan Africa (SSA) due to the patriarchal kinship structures where men tend to have stronger
rights to assets, especially land ownership, thus skewing power relations between spouses (Sell and
Minot 2018; Danso-Abbeam, Baiyegunhi, and Ojo 2020; Gebre et al. 2021). This leads to men having a
higher power in household decision-making in access, utilisation of assets and control of income
generated from economic activities, hence lowering womens bargaining power (Osanya et al. 2020).
Dierences in productivity across plot managers, which refers to the person involved in making
day-to-day farming decisions on a plot have been attributed to gender-specic constraints in access
to farm inputs leading to lower and unequal levels of fertiliser, labour, and land use (Palacios-Lopez

and Lopez 2015; Khan et al. 2021). Access to institutional support services, such as information and
credit facilities, by female plot managers is limited compared to male-managed plots (Sell et al.
2018). In addition, female plot managers in SSA have more limited access and weak tenure security
over land than male farmers (Chigbu, Paradza, and Dachaga 2019). However, where there is joint plot
management, these constraints have been addressed to some extent due to the complementary role
played by men (Miriti et al. 2021).
The majority of studies on gender gaps in productivity use the household head as a proxy to esti-
mate plot-level outcomes rather than the plot manager who is directly involved in the plot activities
(Kilic, Palacios-López, and Goldstein 2015; Mukasa and Salami 2016; Mugisha et al. 2019). There is a
likelihood that the household head is not the person responsible for making farm-level decisions.
Therefore, associating the household head with farm productivity may lead to inaccurate pro-
ductivity measurements (Kilic, Palacios-López, and Goldstein 2015). The present study attempts to
address this knowledge gap by using plot manager to reduce the gender gap.
We provide rigorous evidence on gender gaps in productivity between male- and female-
managed sorghum plots using the OaxacaBlinder decomposition approach by taking into
account observable and unobservable factors, examining productivity dierences and their determi-
nants in Uganda. The rest of the paper is organised as follows. Section 2 comprises the methodology
highlighting the study area, sampling, and the empirical analysis. Section 3 presents the results and
discussions while Section 4 provides the conclusion and policy implications.
2. Methodology
2.1. Description of the study area
The study was undertaken in the Lira, Serere, and Kumi districts of Uganda, which are the predomi-
nant sorghum producing areas (Figure 1).
Lira district lies in the Northern part of Uganda at a latitude of 2.2316° N and a longitude of
32.9438° E. The district receives about 1300 mm of rainfall annually and approximately 71% of its
residents depend on subsistence farming for their livelihood (UBOS 2017a). Serere district lies at a
latitude of 1.4994° N and a longitude of 33.5490° E in Eastern Uganda. In the 2012 national popu-
lation census, the district had a population of approximately 294,100. The district receives an
average of 1250 mm rainfall annually, and has an annual mean temperature of 25° C (UBOS
2017b). Kumi district is located in the Eastern region of Uganda at a latitude of 1.4877° N and a longi-
tude of 33.9304° E and has a population of about 255,500. The district receives an average of about
900 mm rainfall, and has a mean annual temperature of 24° C (UBOS 2017c).
2.2. Data sources and sampling
The study used plot-level gender-disaggregated data collected by the International Crops Research
Institute for the Semi-Arid Tropics (ICRISAT). A multi-stage sampling procedure was used to identify
study areas and respondents. In the rst stage, the Kumi, Lira, and Serere districts were selected pur-
posively because they predominantly produce sorghum for food security and commercial purposes.
In the second stage, four sub-counties within the districts with the highest sorghum production were
selected: Amach and Agali sub-counties in Lira, Katete in Kumi, and Mukongoro in Serere. In the third
stage, a systematic random sampling procedure was used to select respondents within the four sub-
counties who were then interviewed using structured questionnaires. A total sample of 362 (182
male plot managers and 180 female plot managers) were interviewed 47% from Lira, 31% from
Serere, and the rest from Kumi district which were allocated proportionately to their population
sizes. The necessary ethical approvals were obtained before the study commenced from the Insti-
tutional Ethics Committee (IEC) at ICRISAT and informed consent from all farmers was sought
before the interview process.

2.3. Empirical analysis
The data collected was downloaded from the Open Data Kit (ODK) and analysed using Stata 15 to
obtain frequencies, mean, standard deviations of socio-economic characteristics, and estimation
of determinants of sorghum farmers. Productivity estimates for male and female managed plots
were estimated following the partial factor productivity (PFP) equation as follows:
PFPai =Ya
Xai
(1)
where PFPai denotes the partial factor productivity of plot a under plot manager a,Yais the output
(sorghum yield in kilograms) from plot a, while Xai is the primary input (land in hectares) used for plot
aby the plot manager i. Since the dependent variable is continuous in nature, the Ordinary least
square (OLS) regression was tted to evaluate determinants of sorghum productivity following

Udry et al. (1995), who expressed a simple productivity function as:
Yai =

where Yai = sorghum productivity (kgs/ha) of plot aunder manager i;Xai denotes variables used,
such as age, years of formal schooling completed, years of sorghum farming experience, household
size, distance to plot from homestead, amount of seed used, hired labour, family labour, access to
credit, access to extension services and farmer group membership; Gai is a dummy variable denoting
the gender of the plot a; and
m
ai is the error term.
The approach of estimating determinants discussed in Equation 2 does not give insights on rela-
tive contribution of the vectors of covariates to the gender productivity gap (Joe-Nkamuke et al.
2019). In order to account for this, we adopt the OaxacaBlinder decomposition approach
(Oaxaca 1973; Djurdjevic and Radyakin 2007). The decomposition technique is increasingly being
applied in gender and productivity studies (see for example, Kilic, Palacios-López, and Goldstein
2015; Bello et al. 2021; Nchanji et al. 2021; Singbo et al. 2021). The approach starts by estimating
the expected yield value per ha for the male (m) and female (f) plot managers as presented in
Equation 3:
E(Yg)=ag+E(Xg)
b
g(3)
where gdenotes the gender of the plot manager,
a
is the intercept,
b
is the slope coecient, and X
denotes independent variables. The gender gap in mean productivity between the male- and
female-managed plots is expressed as follows:
Gender gap =E(ym)E(yf)=
s
m+E(Xm)
b
m
s
fE(Xf)
b
f(4)
The gap in the equation above can further be decomposed into two parts, where the rst part is
composed of the gender gap that is explained by the male and female dierences, and the
second part consists of the unexplained part (Oaxaca 2007). Therefore, it can be expressed as:
Gender gap =Q+U(5)
where Qdenotes the gender gap due to the dierences between the male and female plot managers
and can be expressed as:
Q=[E(Xm)
E(Xf)]
b
(6)
where
b
represents the non-discriminatory coecients. The second part of Equation 5 is referred to
as the unexplained Uor the structural eect and it accounts for the dierences in returns or the dis-
crimination between the male and female plot managers. Following Fortin, Lemieux, and Firpo
(2010), it can be expressed as follows.
U=(

Equation 7 can be subdivided further into two components:

b

b

and
Uf=(
a

where Equation 8a represents the discrimination in favour of the structural advantage of the male
managed plots and Equation 8b denotes the discrimination or the structural disadvantage of the
female managed plots (Oaxaca 2007; Fortin, Lemieux, and Firpo 2010).

3. Results and discussion
3.1. Socio-economic characteristics of the respondents
Table 1 shows the summary statistics of the interviewed plot managers. The majority of sorghum
plot managers were adults with less than seven years of formal education although male plot man-
agers had a relatively higher number of years spent in school. This shows that rural sorghum farmers
in Uganda have little formal human capital.
The average years of sorghum production for the plot managers were more than ten years for the
two groups, showing that the majority of the farmers have been growing sorghum for quite a long
time. The World Bank (2018) similarly noted that in Uganda, about 70% of households rely on agri-
culture as a source of livelihood. The mean household size for the male- and female-managed plots is
slightly above the national mean household size of 4.7 persons, which has remained relatively stable
in the last decade (UBOS 2016). This variance from the national household means can be explained
by the polygamous nature of rural households where the study sites are located.
The mean plot size of sorghum farmers is less than two hectares, implying that they are small-
holder farmers. This is consistent with Cervantes-Godoy (2015) who dened smallholder farmers
as those owning less than two hectares of land. However, the average plot size in the three study
areas is below the national average farm size of 0.97 ha (Priegnitz et al. 2019). This can be attributed
to the subdivision of agricultural land due to rapid population growth and its attendant pressure on
productive resources, such as arable land.
Distance to the plot from the homestead was larger for male plot managers; this could be attrib-
uted to the likelihood of farmers leasing land from various areas to increase prot margins. For farm
inputs such as hired labour, family labour, and the amount of seed and fertiliser used, male plot man-
agers had higher quantities compared to female plot managers. This corroborates Palacios-Lopez,
Christiaensen, and Kilic (2017) who observed that female plot managers have lower access to and
utilisation of farm inputs. We observe a similar pattern for access to credit facilities, access to exten-
sion services, and farmer group membership. Lastly, the age of the plot manager, years completed in
school, household size, plot size, farmer group membership, and access to credit were signicantly
dierent between the two groups.
3.4. Measurement of sorghum productivity
Sorghum productivity was computed using plot-level data on the male-managed plots, the female-
managed plots, and the pooled sample. Male plot managers had the highest productivity (850.6 kgs/

ha) compared to the female managed plots (832.6 kgs/ha) and the pooled sample (841.6 kgs/ha).
This nding is similar to Djurfeldt et al. (2019); (Miriti et al. 2021), and Singbo et al. (2021), who attrib-
uted it to male plot managerssuperior access to productive resources and institutional support ser-
vices. The productivity of the male-managed plots, the female-managed plots, and the pooled
sample is presented through a kernel density plot in Figure 2.
Further, Peterman et al. (2011) noted that female farmers have lower human capital, resource
bases, access to, and utilisation of farm inputs than male farmers, hence they have low ability to
respond to subsidy programmes and agricultural incentives, thus leading to low productivity. More-
over, female plot managers spend more time on domestic chores than male plot managers, as well
as taking disproportionate responsibility of care for their children, thus limiting the time they spend
on their plots (Donald et al. 2018). Consequently, this impacts negatively on the productivity of their
sorghum plots.
3.5. Determinants of sorghum productivity
Results show that years of formal learning positively inuences sorghum productivity for female
managed sorghum plots (Table 2). Formal education plays a crucial role in decision making, especially
in the use of better inputs. This corroborates ndings by Wouterse and Badiane (2019) that invest-
ment in human capital, such as education, stimulates productivity. Similarly, the age of the plot
manager is positive and signicant for the female plot manager. Therefore, a one unit increase in
the age of a female plot manager would lead to a 9% increase in productivity, which can be attributed
to the possibility that older female plot managers may have a higher access to productive resources
and institutional support services than younger women (Ingutia and Sumelius 2022).
However, household size has a negative and signicant eect on sorghum productivity for the
female-managed plots. Rural sorghum farmers are resource-poor and tend to have large household
sizes. This corroborates the socio-demographic characteristics in Table 1, where the mean household

size was higher than the national average. This increases expenses on food and health services for
the household, thus limiting resources available to invest in farm inputs. As noted by Mango et al.
(2015), this results in low technical eciency, thus lowering productivity.
Interestingly, the coecients for labour (both family and hired) were positive and signicant for
the male-managed plots, female-managed plots, and the pooled sample. However, the amount of
seed used was positive and signicant for the male-managed plots and the pooled sample.
Similar results were observed by Kloss and Petrick (2018) and Anang et al. (2022), who argued
that proper utilisation of farm inputs enhances crop productivity.
There was a signicant inverse relationship between plot size and sorghum productivity for all
categories of plot managers; the largest decline is in male-managed plots (2.42). Empirical evidence
has shown that small farms are more manageable, thus increasing eciency in utilisation of farm
inputs as well as close monitoring of farm activities. These results are consistent with Muyanga
and Jayne (2019) and Sheng, Ding, and Huang (2019), who found that productivity tends to
decline as the farm size increases.
Access to extension had a negative and signicant eect on sorghum productivity for female-
managed sorghum plots. This shows that male plot managers who had extension services were
less productive than those who did not. This could be explained by three possibilities: improper
application of the services by the plot managers, the extension service provided was not specic
to sorghum growing, or the services were not suitable for the local agro-ecological condition. This
nding corroborates Abate, Dessie, and Mekie (2019). On the other hand, Mwololo et al. (2019)
and Rajkhowa and Qaim (2021) argue that access to extension plays a critical role in farmers
ability to diversify farming enterprises, which leads to increased productivity.
3.6. OaxacaBlinder decomposition of the gender agricultural productivity gap
As noted in Section 2.3, the application of OLS in gender and productivity studies does not account for
the contribution of the explanatory variables to the gender gap. Table 3 presents the decomposition
estimates on the dierential in the log of the productivity value between male and female sorghum
plot managers. The OaxacaBlinder decomposition in terms of endowment and structural eects
oers detailed insights into the magnitude of the contribution of observable factors to the gender gap.
The estimates are grouped in three parts; the rst part (mean gender dierential) presents the
observed mean gender gap in productivity of 18.3%. This shows that, on average, sorghum plot

managers are 18.3% signicantly more productive compared to female-managed plots. The second
part consists of the aggregate decomposition in terms of the endowment eect which accounts for
the gender gap in terms of socio-demographic dierences between male and female plot managers
and also includes the structural advantages and disadvantages. The aggregate endowment signi-
cantly accounts for 4.7% of the observed gender gap between the male and female plot managers
and it explains 10% of the mean gender productivity dierential. Likewise, the male structural advan-
tage and female structural disadvantage signicantly explain the mean gender productivity dieren-
tials of 57% and 33%, respectively. Similar ndings were reported by Kilic, Palacios-López, and
Goldstein (2015); Joe-Nkamuke et al. (2019); and Singbo et al. (2021).
The third part (detailed decomposition) captures the magnitude of contribution or reduction of
the gender gap in productivity where a positive coecient increases the gender gap while a nega-
tive coecient reduces the disparity (Nchanji et al. 2021). The amount of seed, hired labour, access to
credit, and farmer group membership contributes positively to the endowment eect, thereby
exacerbating the gender gap in sorghum productivity between the male- and female-managed
plots. On the other hand, years of farming sorghum and use of family labour reduce the endowment
eect; therefore, it reduces the gender gap.
The age of male plot managers, hired labour, and membership of farmer groups contributes posi-
tively to the male structural advantages, which, in turn, act as positive contributors to the gender
gap, while the household size and access to credit play a role in reducing the gender productivity
gap. Similar ndings were reported in Malawi by Nsanja, Kaluwa, and Masanjala (2021). On other
hand, the amount of seed and use of family labour reduce the structural disadvantage of female
plot managers, thus reducing the gender gap, while we nd that access to extension services and
the plot size increase the gender gap.
Generally, the main driver of the gender gap in sorghum production is the structural advantage of
men (57%) which corroborates Addai, Ngombe, and Temoso (2022), who reported that gender gaps
in Ghana are signicantly attributed to mens structural advantages. However, our results dier from
those of Joe-Nkamuke et al. (2019), who found that a 76% gender gap in Malawi was due to the
endowment eect. Singbo et al. (2021) reported that the main driver of the gender gap remained

unexplained (56%) by the structural disadvantage of women in Mali. Therefore, drivers of gender
gaps in productivity vary from one context to another.
4. Conclusions and policy implications
This study assessed productivity dierentials between male- and female-managed sorghum plots
in Uganda. An Oaxaca Blinder decomposition technique was applied to quantify the magnitude
of the gender productivity dierentials. Overall, the male-managed plots were found to be more
productive than the female-managed plots. The amount of seed, family, and hired labour had
signicant positive eects on the productivity of male-managed sorghum plots. Age, access to
extension, family, and hired labour positively inuenced the productivity of female-managed
plots. On average, male-managed plots are 18% more productive than female-managed plots.
About 57% of the gender dierential in productivity is accounted for by the male structural
advantages. Access to extension services, access to credit, and the amount of hired labour are
the most important factors that constitute the endowment eect. These ndings oer novel
insights for enhancing equity and progressive development through the empowerment of
female plot managers. Due to the relative contribution of access to extension services to the
gender gap, the government should put in place systems that promote ecient dissemination
of extension services, especially to female plot managers. Private agricultural companies and
non-governmental organisations that are involved in the provision of extension services should
oer gender-inclusive and tailor-made services to farmers. For example, women farmers require
a specialised agricultural extension that can help ease the double role they play as household
caregivers and as farmers to improve the participation of female farmers and increase access
and utilisation of farm inputs.
Access to agricultural credit by female plot managers can be facilitated by the legislature through
the formulation of banking rules that favour female farmers. For instance, oering exible repayment
terms, lower interest rates, and credit facilities that are demand-driven and use of other forms of col-
lateral besides land, such as womens group guarantees, can help increase uptake of nancial pro-
ducts by female plot managers.
Female structural disadvantages, such as the size of plot owned and access to extension services
by female plot managers, are greatly inuenced by cultural and social norms; these calls for contin-
ued behavioural research on gender dynamics to promote the dissemination of information and
interventions aimed at showcasing the importance of enhancing womens land rights and access
to institutional support services, such as agricultural extension.

Purpose: The study aimed at determining the gender gap in agricultural productivity: A case of Smallholder Farmers in Busia Kenya. Methodology: The research employed a correlational research approach, utilizing multistage sampling to choose 384 participants from seven sub-counties within the study region. Data collection utilized structured questionnaires, and analysis was conducted on quantitative data using descriptive statistics and inferential methods with STATA version 17. The findings were presented using tables and figures. Findings: The study revealed a statistically significant gender gap in agricultural productivity in Busia-County at the expense of female farmers. Specifically in Teso North, gender gap was -0.43 with a p-value of 0.049, in Teso south, gender gap was -0.63 with a p-value of 0.040, in Bunyala, gender gap was -0.67 with a p-value of 0.035, in Butula, gender gap was -0.47 with a p-value of 0.002, in Matayos, gender gap was -0.72 with a p-value of 0.041, in Nambale, gender gap was -0.64 with a p-value of 0.041 and In Samia, gender gap was -0.67 with a p-value of 0.036. It was concluded that female farmers are less productive than male farmers in Busia County Kenya. Unique Contribution to Theory, Practice and Policy: Drawing from production theory, and social feminist theory, the study investigated the relationship between productivity and gender among smallholder farmers. To address the gender gap in agricultural productivity, it is recommended that policymakers, agricultural extension services, and other stakeholders advocate for gender-inclusive agricultural development initiatives in the area.

A sorghum Value Chain Analysis (VCA) was undertaken at the Bubaare Sorghum Innovation Platform (IP). The analysis points out that the chain starts with seed production and distribution to small-holder IP farmers who are the main players in production and marketing. Based on the VCA, innovation opportunities exist in Uganda that can influence expansion of sorghum VC for enhanced socioeconomic gains of all the actors. Some of the identified opportunities among others include increasing farm level production through enacting supportive policy and providing support to National Agricultural Research System (NARS) sorghum processing, and increasing their capacity as well as that of the existing processing entities.

We examined gender-based household welfare differences in Ghana among smallholder households. We measured disparities in welfare outcomes (food poverty, vulnerability, and food consumption inequality) across male and female household heads and identified the set of covariates influencing them. The study utilizes a dataset from a farm household survey undertaken in Northern Ghana from October to December 2018. A multistage sampling approach was adopted in selecting 900 farm households. The Oaxaca–Blinder mean and Recentered Inference Function decomposition techniques highlighted the sources of gender differentials in household welfare outcomes. The findings indicate a significant gap in food consumption expenditure per capita and household dietary diversity scores between male- and female- headed households, and these gaps are as high as 28.2% and 18.1%, respectively. However, there are no statistically significant differences in vulnerability to food poverty between male- and female-headed households. The Lorenz curves confirm inequality in gendered households’ food consumption expenditure and dietary diversity scores. This study highlights the existence of systemic female-headed household vulnerability to food poverty in Ghana. This study provides significant evidence of the need for policymakers to address food systems’ structural deficiencies and inequalities with gender in mind.

Farm productivity in most developing countries remains low, hence the need to enhance technical efficiency (TE) of producers. This study evaluates the TE of maize production in rural Ghana, using primary data from a survey of smallholder producers. A two-stage double bootstrap data envelopment analysis (DEA) approach was used to assess TE and its determinants. The results revealed a bias-corrected mean TE of 68% (as opposed to 81% using the traditional DEA approach). Hence, with the prevailing technology and current input levels, farmers can increase their TE of maize production by 32%. TE increased with adoption of improved varieties, weeding frequency, and herd size but decreased with producer’s age, household size, educational status, and group membership. Subsequently, these factors need to be carefully considered in targeting policies for increasing maize productivity. The study observed increased adoption of improved varieties and training in efficient methods of weed control as important measures to enhance TE of maize farmers.

Productivity growth in smallholder agriculture is an important driver of rural economic development and poverty reduction. However, smallholder farmers often have limited access to information, which can be a serious constraint for increasing productivity. One potential mechanism to reduce information constraints is the public agricultural extension service, but its effectiveness has often been low in the past. Digital technologies could enhance the effectiveness of extension by reducing outreach costs and helping to better tailor the information to farmers' individual needs and conditions. Using primary data from India, this study analyses the association between digital extension services and smallholder agricultural performance. The digital extension services that some of the farmers use provide personal-ized information on the types of crops to grow, the types and quantities of inputs to use, and other methods of cultivation. Problems of selection bias in the impact evaluation are reduced through propensity score matching (PSM) combined with estimates of farmers' willingness to pay for digital extension. Results show that use of personalized digital extension services is positively and significantly associated with input intensity, production diversity, crop productivity , and crop income.

Although women are actively involved in a wide array of agricultural production activities, they have limited access to farm productive resources and their influence in decision-making is also restricted compared with men. These limitations have the potential to affect women performance in agriculture. This study assesses gender-based farm performance (proxy by productivity) differences and identified sources of performance differentials among rice farmers in rural Nigeria using the Blinder-Oaxaca gender decomposition framework. The results revealed a disparity between men and women with a gender performance gap of about 11% in favour of men, of which 77.66% of the gap remained unexplained after accounting for gender differences in household characteristics, access to supply-driven factors, and farm productive resources. A more detailed analysis suggests that factors such as the use of improved rice varieties, membership of farmer-based organizations, extension services, and quantity of seeds sown could contribute to the gender performance gap. As a result, the study concludes that focusing on these productivity gaps and the factors that contribute to them is critical for developing policy interventions aimed at empowering women.

Production by smallholders in rural Kenya is limited by institutional, technical and investment constraints. Female farmers are the majority among smallholders and have significant roles in agriculture; nonetheless, they face constraints in accessing resources. Recent primary data of 347 farmers (proportional random sampling) was used to examine: (a) factors affecting women’s participation in agriculture; (b) factors influencing female farmers’ decision to join a farmer group; and (c) the effect of women’s membership in a farmer group on crop yield. We applied Probit and linear regression with endogenous treatment maximum likelihood methods. Results reveal that women’s participation is positively influenced by membership in a farmer group and land ownership. Women’s decision to join a farmer group is positively affected by access to credit, and negatively by limited decision-making power and lack of access to land. Crop yield is positively affected by membership years in a farmer group and ownership of mobile phones, negatively by lack of credit. Farmer groups are a particularly effective platform to improve crop yields and other constraints confronting female farmers. Surprisingly, this platform is under-utilised. Policymakers should invest in human, financial and physical capital of farmer groups as a pathway to rural development, improved rural livelihoods and reduced poverty.

Sorghum plot managers in different locations have varying levels of resource endowment that in turn influence technical efficiency (TE). Therefore, plot managers operate at different levels of technology. The present study applied a stochastic metafrontier approach to assess TE and technology gaps of female, male and jointly-managed sorghum plots. A two limit-Tobit model was subsequently applied to assess determinants of TE. Results indicate that male-managed sorghum plots had the highest metafrontier technical efficiencies (MTEs) (61%, 56% and 15%) and technology gap ratios (TGRs) (98%, 92% and 20%) for Lira, Serere and Kumi districts, respectively compared to female and jointly managed plots. However, jointly managed plots had higher TE and TGRs compared to female plot managers but lower than those of the male-managed plots. Age, distance to plot and farmer group membership influenced TE positively while household size, years of farming sorghum and access to credit had negative effects on efficiency.

This article examines the relationship between caste, land ownership and agricultural productivity in India, utilising data from a large-scale survey of farm households. Access to resources like information, technology, inputs, markets, and support institutions are important for sustainable and inclusive growth of agriculture. The results indicate that socially disadvantaged households (Scheduled Castes and Scheduled Tribes) have lower access to land and also other resources, but they produce more output per unit of land because they are more diversified towards high-value crops that generate more returns and are labour intensive. This calls for policy emphasis on crop diversification in the agricultural sector.

This paper decomposes the gender agricultural productivity gap and measures the factors that influence the gap between male and female agricultural plot managers in Mali. The Oaxaca–Blinder approach and the recentred influence function (RIF) decomposition methodology are applied to a nationally representative survey of Mali. The results show that the agricultural productivity of female plot managers is 20.18% lower than that of male plot managers. Additionally, while more than half (56%) of the agricultural productivity gap is influenced by female-specific structural disadvantages, 44% of the gap is due to an endowment effect. Socio-economic characteristics such as the educational level and age of the plot manager, environmental factors and agricultural production practices, i.e., the differential use of inputs (organic or inorganic fertiliser and improved seeds) and the use of hired female workers seem to affect the female-specific structural disadvantages. To reduce or close the gender productivity gap, the underlying causes of female-specific structural disadvantages must be addressed to enable female farmers to obtain the same returns as men. Traditional means of addressing the gender gap, such as providing education for women in rural areas and facilitating rural women’ access to extension services and improved seeds, can mitigate the endowment deficit. This paper highlights the need to develop a better understanding of the factors influencing the structural disadvantages faced by female farmers in Mali that could feed into the development of more effective policies to address the gender gap in agricultural productivity, improving productivity and gender equity and reducing poverty.

This study examines the extent of the productivity gap between male and female bean producers, its discriminatory nature and implications for the policymakers in agriculture in Tanza-nia. Generally, women are distinctively "invisible" in agriculture, due to social norms and even from the national agricultural policy perspective. Their discrimination arises from uncounted and unaccounted for farm work, and their productivity is reduced by triple roles, limited access to education , having triple effects on access to technology, training and land rights. In research, issues of concern to them such as nutritious food crops, varietal selection on important attributes, household food security, convenient home storage and small-scale processing are widely ignored through unfavourable policy design. Given the above discriminatory issues surrounding women in agriculture, they are hypothesised to be less productive and often lag behind male counterparts in crop production. To test the above hypothesis, a three-stage stratified sampling method was used to collect cross-sectional data in 2016 across four regions of Tanzania. Then, an Oaxaca-Blinder decomposition method (at means) was used to apportion the sources of the difference between men and women into explained and unexplained variations. Further improvements through the newly developed Re-Centered Influence Functions (RIFs) remarkably improved outcomes as the differences were analysed through unconditional partial effects on quantiles. Using a counterfactual approach and correcting for selection bias, the model provided consistent estimates for easy comparison of the two groups. Besides this, it emerged that interventions such as providing improved bean seed varieties and training farmers on good agricultural practices reduced the gender yield gap and provided a potential avenue for addressing the discrimination observed in productivity among males and females. Controlling for selection bias also improved the model, but the real discrimination was observed at the 50th percentile, where the majority of the respondents lay within. However, if a female's age, family size, additional years of schooling and discretion to spend income from beans were taken away, they would be worse off. Our study finds that females comprised 25 percent of the sample, had 6 percent lower productivity, provided 64.70 percent on-farm labour and had 0.32 hectares less land compared to males, ceteris paribus. Access to improved varieties contributed to a 35.4 percent improved productivity compared to growing indigenous/local varieties. The implication is that the gender yield gap can be reduced significantly if efforts are focused on preventing or correcting factors causing discrimination against women.
