Abstract

The study was conducted in eight selected villages in the Chittagong Hill Tracts (CHT) of Bangladesh aiming to perceive the socio-economic impact of bagging technology on farmer’s income and livelihood and to know the factors affecting adaption of pre-harvest mango bagging technology. Findings of the study revealed that a few varieties in particular BARI Mango 4, BARI Mango 8, BARI Mango 3, Mallika and Arshina were reported to be the most preferred varieties for bagging because of less pest attacks, attractive color and higher market prices. The average market price received from bagged mango was 74% higher than non-bagged mango. The difference of average gross margin of bagged and non-bagged mango was recorded Tk.22790 per ton which implies that bagged mango was more profitable than non-bagged mango. According to the survey report on an average 15.7% of the annual gross income was increased due to adoption of bagging technology whereas this technology contributed 25.13% increment in income from mango selling. About 96% of the respondents admitted that they were able to control fruit flies and 92% of them confirmed that they were able to produce safe and toxicity free fruits utilizing pre-harvest bagging technology. The price of bagged mangos, training, research contacts, extension contacts, risk taking behavior and willingness of farmers influenced the adoption process significantly. This technology should be disseminated for the welfare of the hilly areas with maintaining proper time and methods.

Contribution/ Originality

This study is one of very few studies which have investigated the socioeconomic impact of pre-harvest bagging technology on livelihoods of CHT mango growers of Bangladesh through value addition and the factors influencing the rate of adoption of bagging. As a new concept in the CHT, this study is original. 


1. INTRODUCTION

Fruit bagging is the practice of putting bags over fruits to protect them from pests, disease and other harmful elements. Pre-harvest fruit bagging is gaining popularity among the mango growers all over the world as an effective alternative to chemical pesticides. This eco-friendly method has been adapted by more farmers after successful use of it in different orchards last few years. Bagging prevents pests, especially fruit flies, from damaging mangoes and checks latex burns, fungal spots and mechanical damages on fruits. The bagging method came as a blessing to farmers against the canvas of widespread use of pesticides; that popped up as a potential threat to the ecological balance and public health (Sharma et al., 2014). Mango growers usually spray pesticides at least 15 to 25 times in their orchards in a season (Islam et al., 2017). But pre-harvest bagging technology  allows escaping that much use of chemicals, that has been considered as one of the greatest threats to the environment as it  requires spraying pesticides for only two to three times at the early stages of fruiting.
Mango (Mangifera indica L.) belonging to the family Anacardiaceous; arguably known as the king of fruits; is one of the most popular tropical fruits especially in Asia and by large the most popular fruit in Bangladesh.  Bangladesh is  currently being the 8th largest mango producing country in the world (Islam et al., 2017) as there are about 25100 hectares of land occupied by mango orchards (Islam et al., 2014) and produces around 10,00,000 tons (Khrishi, 2016).

Several good agricultural practices (GAP) are becoming popular throughout the world for the production of high quality fruit with less dependence on man-made chemicals. Bagging technology has several beneficial effects on internal fruit quality reducing fruit disorders etc (Abdel et al., 2017). Brown paper bag improves fruit color, texture, appearance and sweetness (Islam et al., 2017). Rathore and Pal (2016) recommended for fruit bagging for mango in commercial use to the growers to escape attack of insect- pests and diseases, fruit cracking, and blackening. Rakesh et al. (2017) reported that the fruits bagged with brown paper bag gave better results in all of the parameters (colour, texture, taste, flavor, TSS and carotenoids contents). Kireeti et al. (2018) concluded that different types of bags influenced growth and development of mango fruit and it is one of the best alternatives to avoid adverse effect of recent changes in climate on fruit. Jakhar and Pathak (2016) reported  that the pre-harvest treatment of 2% CaCl2+1% K2SO4+bagging was found superior to improve the quality of fruits in respect of highest fruits weight, firmness, TSS, ascorbic acid, total sugars with minimum black spotted fruits per cent and maintained it throughout the storage period up to 18 days over control. 

The adoption of bagging technology could minimize environmental pollution and accumulation of the ill-effects of chemicals on the health of workers, household members and consumers (Maria, 2009). The chemical parameters such as moisture content, acidity, TSS, reducing, non-reducing sugars and β carotene were not significantly varied due to bagging (Nagaharshitha et al., 2014). Bagging technology saves fruits from pests, improves quality.  Fruit bagging could reduce use of harmful chemicals, insecticides and pesticides to a great extent on the trees (The Independent, 2017). Sharma et al. (2014) reported that pre-harvest bagging of fruit can also reduce the incidence of disease, insect pest and/or mechanical damage, sunburn of the skin, fruit cracking, agrochemical residues on the fruit, and bird damage. The differences in taste, flavor and texture between ripe bagged and non-bagged mango were not significant. Non-bagged fruits had a higher postharvest weight loss than bagged mango (Josphat, 2009). 

The Chittagong hill tract is an area with an enormous potentiality for fruit production. According to BBS (2018) about 6316 ha land is currently occupied in the Chittagong hill tracts under mango production and the recently recorded  production was 14823 m.tons in the year of 2017-18. Besides quality production and better prices the bagging technology has been found to be the most effective economic and environment friendly way to solved production related problems. With this view the following objectives were set (i) to document socioeconomic profile and contextual information of the sample farmers (ii) to estimate the price increments of mango due to adaption of  bagging technology as compared to non-bagging and (iii) to identify the factors effecting  adaption of mango bagging technology and (iv) to know the socioeconomic benefits of bagging technology for mango.

2. METHODOLOGY

2.1. Description of the Area

A survey was conducted in 9 villages in three hill districts of  Chittagong Hill Tracts aiming to perceive the socio-economic benefit of  bagging technology regarding value addition of mango and to know farmers responses to the technology. Multi-stage sampling techniques were followed to select the study areas and sample farmers. The selected villages namely were: Guamahat, Madhupur, Comilla Tila, Protap para, Hafchari in Khagrcahri District; Manikchari in Rangamati and Basantopara and Bandarban Sadar in Bandarban Hill District. The specific locations were selected based on numerical abundance of mango growers who have been adopting bagging technology.

2.2. Sampling Technique Adopted

Purposive and stratified random sampling technique was followed for selecting the samples in each area. In total, 164 mango growers (adopter-117 and non-adopter-47) were selected purposively. As the technology is quite a new one for adoption in the CHT, the sample size couldn’t be extended to strategic standard, but it was enough to represent the areas considering the circumstances.

2.3. Data Collection Procedures

Both primary and secondary data were used in the study. The primary data were collected by using pre-tested semi-structured survey questionnaire. The secondary data were collected from published reports, journal, internet and BBS sources. Face to face interview with respondents were conducted by the scientific assistants, scientific officers and the researcher himself. Several case studies on the mango growers were done in the study areas to know the impact of bagging technology on farmer’s livelihood and yearly household earning in terms of income generation from mango sales. The data collection period was May-August 2018.

2.4. Analytical Techniques

In tabular technique, mean, percentages and mean comparison were used in the study. In statistical technique the Probit regression analysis was done for estimating the contribution of factors responsible for adopting the technology by the farmers. In that case, the independent variables were chosen as: price of bagged mango, family size, family type, education, training, risk taking behavior, willingness, having knowledge on bagging technology and mass media exposures. Two communication variables were included in the study: research and extension contact. Suitable scales were used to measure the variables. The collected data were analyzed using appropriate statistical techniques. One-way ANOVA was used for analyzing the mean differences of the selected variables in all locations. The mathematical expression of the Probit model is given below:

2.5. Probit Model

In order to ascertain the adoption of bagging technology, the following empirical Probit model was employed. Since the dependent variables were dichotomous, Ordinary Least Square (OLS) method was not suitable. Therefore, MLE method was followed to run the Probit model using STATA software. The empirical probit model was as follows:

Ai = α + βiXi + ……..+ Ui

Where,
Ai = Adopter of bagging technology (Adoption of the bagging technology= 1; Otherwise = 0).
α = Intercept.
Xi = Explanatory variables.
βi = Coefficients of respective variables.
Ui = Error term.
The adoption impact of bagging technology is likely to be influenced by different explanatory variables.
The variables are
X1 = Ln price of bagged mango (tk/kg).
X2 = Family size (no.).
X3 = Family type (score).
X4= Education of the respondents.
X5 = Training (score).
X6 = Risk taking behavior (score).
X7 = Willingness (score).
X8 = Having knowledge on bagging technology (score).
X9 = Mass media exposure (score).
X10 = Research contact of the farmers (score).
X11 =Extension contact of the farmers (score).
The analytical results of the model are shown in the next section.

3. RESULTS AND DISCUSSION

3.1. Socioeconomic Profile and Contextual Information of the Respondents

Table 1 revealed that the average age of the respondents was found to be 43.8 years; implied that most of the respondents belong to the young age category. In case of education of the respondents, the average year of schooling was found to be 11.2 years in all locations; that explains the cause of willingness of the respondents to adopt new technologies. The major occupation of the respondents was agriculture (100%). The secondary occupation was reported to be business (40.0%) followed by private jobs (20.0%). The average household size was found to be 5.92; which was higher than the average household size (4.06) of Bangladesh (BBS, 2018). Most of the respondents were belonging from single family (84.0%). The average cultivable land per household was 7.88 ha and the average size of mango orchard was 5.94 ha. The mean differences of the cultivable land and average area of mango orchard was found to be significant at 5% (F=5.312) and 10% (F=2.111) level of probability, respectively.

As shown in ‘Table 2’’ the respondents had quite a collection of BARI and local varieties of mango. The cent percent (100%) of the respondents reported to have BARI mango-3(Ammropali) in their orchards. The second highest preferred variety was BARI Mango 8 (Ranguai) followed by BARI Mango-4 (80%). Among the local varieties Mollika had the highest rating (64%). Regarding preferences for bagging, BARI Mango 4 became on top of all (96.2%); followed by Mollika (87.0%) and BARI Mango-8 (Ranguai) (82.3%).

Table 5 shows that the average selling price of bagged mango was found to be Tk.60.59 per kg irrespective of all varieties where Tk. 25.77 per kg was found difference with non-bagged mango. Its revealed that about 74% higher prices was received for bagged mango in the study areas. The mean differences of bagged mango prices were varied significantly at 5% level of probability among the sample farmers.

Table 5 revealed that the price of bagged mango was greater than non-bagged mango by 74%. The difference of average price per kg was recorded at Tk. 25.77 irrespective of all mango varieties. Among the mango varieties, the highest price increment by 88.4% was found for BARI mango 4 followed by BARI mango 3 and BARI mango 8.

Table 6 shows that the difference of average gross margin between bagged and non-bagged mango was recorded at Tk.22790 per ton, implies that the bagged mango was more profitable than non-bagged mango due to its higher market price. Table 7 revealed that 15.7% annual gross income increased due to adoption of bagging technology irrespective to all interviewed farmers; whereas it was 25.13% increment over income from mango selling.

Table 8 shows that about 96% of the respondents mentioned that they were able to control fruit fly trough bagging technique, whereas 88% of them admitted that they got attractive color and spotless skin (92%) of bagged mangoes. Around 76% of the respondents agreed upon getting higher market prices and 88% of them thought it was more profitable. Almost cent percent of the respondents were happy as their reputations (100%) were built up and had their social status uplifted (84%) with increased self satisfaction (84%) through mango bagging.

As shown in “Table 9” that some other issues had been come up as the respondents mentioned them along with the benefits as well; where 78% of the respondents claimed that harvesting time of bagged mango couldn’t  be exactly determined. About 64% of them claimed not to have proper knowledge of bagging. About 24% respondents claimed the sweetness of the bagged mango to be lower and some mentioned about the unavailability of quality bag (42%).

3.2. Factors Influencing Adoption of Bagging Technology

In order to review the contribution of various factors to the extent of adoption of bagging technology at farm level, a regression equation was applied with dependent variables (0 and 1) and 11 independent variables; mentioned in the methodology section.

The results of the analysis are presented in “Table 10” and “Table 11”. The price of bagged mango is a significant determinant of decision to adopt this technology. The net margin was recorded for bagged mango and non-bagged.

Table 10 shows that the marginal effect of the relevant variables for price of bagged mango, training, research and extension contact and risk taking behavior were estimated at 0.332, 2.18, 2.22, 1.15 and 0.512 implying that a one per cent increase in price of bagged mango, the training, research, extension contact and risk taking behavior will increase the adoption of bagging technology significantly by 0.33, 2.18 and 2.22, 1.15 and 0.512% respectively. On the other hand, the marginal effect of the variable, willingness to adopt this technology is estimated at 0.34 implying that a one per cent increases in the willingness will increase the adoption of those technology by 34% “Table 11”. The results of regression analysis revealed that the income from bagging mango, training, research and extension contact, risk taking behavior and willingness has indeed helped in contributing to adopt this technology at farm level. Out of these, family size, family type and mass media exposure can be seen as insignificant but positive indicator of formulation of adoption  of  bagging technology in the region.

Marginal effect after probit y = 0.5909 (*) dy/dx is for discrete change of dummy variable from 0 to 1.
Note: The marginal effect is the average change probability when x increases by one unit. Since a probit is a non-linear model, that effect will differ from individual to individual.

4. CONCLUSION

Bangladesh has been an agricultural country since the very beginning of its birth.  Agriculture has been always the main driving force of our economy. It is in present already acknowledged as one of the countries which have achieved self sufficiency in food. As intention to get to the next level, the government is giving emphasis of value addition and uplifting the nutritional value of the crops; altering nutritionally single value crops with multi valued crops like fruits and vegetables. To execute the process the government is willing to introduce new modern technologies to agriculture sector. Fruit bagging is one of those revolutionary technologies which brought benefit to all the people from different poles; from fruit growers to traders and consumers. Though bagging technology had been introduced in the plane land of Bangladesh much earlier, but the idea is almost new in CHT for adoption. Based on the survey results it seems like the respondents were heavily influenced with the impact of bagging technology on their socio-economic conditions and livelihoods. Though unlike the other parts of the country, mango bagging is still a new concept in this region; but the great responses and acceptance from the consumer level and the ostensible benefits of the technology made the farmers believe in it. The income from bagged mango, training, research, extension contact, risk taking behavior and willingness of farmers influenced to adopt bagging technology significantly. Finally, considering the benefits of bagging technology, it should be disseminated throughout the CHT through the Department Agriculture Extension (DAE) and NGO’s for increasing farmer’s income to a greater extent.

5. RECOMMENDATIONS

To spread out the benefit of pre-harvest bagging technology a series of recommendation could be made: (i) Conducting promotional activities is the best way to get to the farmers with the technology. Proper initiatives could be taken by the Department of Agricultural Extension in collaboration with other governmental and nongovernmental sectors,  different sorts of means can be used like, documentaries, radio and TV programs, visual, audio visual, posters, leaflets, articles on news papers etc. (ii) Arranging intensive campaigns and training programs.

(iii) Some initiatives to motivate the farmers should be taken, like disseminating fruit bags free of charge or provision of aids and subsidy from the government. (iv) Conduction of more research works both in technical and socioeconomic aspects; for example of technical aspects: impact of using different kinds of fruit bags, time of bagging, change of physiochemical properties of fruits due to bagging etc.
