Abstract:
Ethiopia is endowed with great biodiversity and the population has access to potentially many
underutilized plant species with both nutritional and medicinal benefits. Moringa stenopetala
here after named Moringa, is one of the most valuable and multi-purpose underutilized plant.
This study analyzes Moringa tree-based agroforestry practice, market participation decision,
and its impact on smallholder farmers‟welfare in Segen area people zone to fill the existing
knowledge gap. Descriptive statistics and econometric models were employed to analyze the
data. Tobit model, Double Hurdle model, Endogenous Switching Regression model, Generalized
Propensity Score Approach, and Seemingly Unrelated model were used to identify the
determinants of adoption of Moringa tree-based agroforestry practice, determinants of intensity
of market participation decision, potential welfare impact of the status and intensity of market
participation on farm households, and their interdependence respectively. A cross-sectional data
from 385 smallholder farmers were used in the analysis. The Tobit model result revealed that
age, farm size, family size, training in any agroforestry-related activity, access to extension
services, awareness of the market for Moringa product, livestock owned, and economic
incentives of Moringa plant positively and significantly influence the intensity of MTBAFP
adoption. Education, family size, contacts with extension agents, farm size, training, livestock
owned, and access to transportation means were positively and statistically significant in
determining both market participation and intensity of participation. Similarly, access to
Moringa market information encourages market participation whereas the distance to market
exerts a negative influence on market participation. Membership to rural cooperative group and
receiving market assistance from NGOs increase intensity of market participation. Endogenous
Switching Regression (ESR) model that accounts for selection bias was used in impact
assessment. This was further expanded to generalized propensity score (GPS) approach to
evaluate the effects of the level of market participation on welfare of producers. Results from
ESR show that several demographic, institutional, socio-economic, and market factors affect
participation decision and welfare of farm households. Overall, Moringa market participation
has a positive and significant impact on rural farmers‟welfare, but substantial differencial
between the groups are observed. Participation in the Moringa market increases their crop
income, per capita annual consumption expenditure and per-capita daily calorie intake by 24%,
29%, and 45% respectively compared to non-participants. This shows the importance of
Moringa market participation in improving the welfare of poor farmers in the study area. Results
from GPS are also similar as the welfare of households has increased with the intensity of
Moringa market participation. Policymakers, agricultural planners, institutions and
organizations involved in Moringa production and distribution need to consider the key
variables (age, family size, livestock rearing, extension advice, agroforestry training, efficient
XVII
use of available farmlands, awareness on marketing potential and economic incentives of
Moringa plant) identified in this study to forecast more accurately, future Moringa plant
adoption. Similarly, to expand the market for Moringa production, designing appropriate
support from different stakeholders, encouraging and assisting Moringa associations and linking
them with markets, designing market information transmission mechanism, improving marketing
extension services, training, infrastructural facilities and providing farmers with the chance of
attending basic education is critical. Furthermore, policies aimed at reducing the transaction
costs of accessing markets, promoting the tree via different Media, working on rural institution
capacity building, encouraging value addition and market linkages among diverse market
players, pest/disease control, access to secure markets; establishing information sources will
increase both intensity of adoption and market participation
