Flood causes damage to crops,
Yet leaves a healing message.
Pandemic inflicts more shocks,
But does not leave a recovery passage.
Credit is a must for crop production,
Stop its misuse due to corruption.
Enough food ensures the strength grow more,
And helps winning friends in distant shore.
Coronavirus poses serious obstacle in production and harvest of staple food grain. It already cripples agricultural supply chain. A famine like situation looms large. Though authorities ruled out such an extreme possibility, their reassuring remarks did not find a convinced audience. In urban areas, hoarding fever continues unabated. Desperate people defied confinement measures and stood behind the long queue of fair-price-program, operated by Trade Corporation of Bangladesh.
In the face of soaring rice price, I did a little analysis on production of rice and its dependence on agricultural credit and chemical fertilizers. However, I included the credit and fertilizer on separate equations. And I included both only when I wanted to see their contribution in total production of rice. Data gleaned from Bangladesh Economic Review 2018.
Domestic production of rice means growing of three crops--- Aus, Aman, Boro--- round the year. Data from 1996 to 2017 were considered for current analysis. Following panel model was considered:
Prod
it = b
1i + b
2 Cred
it + e
it
Where Prod
it = production of ith kind of rice at t,
Cred
it= credit disbursement for the production of ith rice at t,
b
1i captures individual heterogeneity.
The issue of whether data would be pooled together with a common intercept or a regression function with dummy variable for individual intercept would be constructed was settled with the aid of F-test. F-test statistic for 2 and 62 degrees of freedom , 263.69, appeared to exceed the critical value, insinuating that different intercepts for different rice varieties.
However in estimating the fixed effect I relied on deviation from individual means. So my model looked like:
῀Prod
it = b῀Cred
it + ῀e
it
Where ῀Prod
it = Prod
it - ‾Prod
i
῀Cred
it = Cred
it - ‾Cred
i
‾Prod
i= mean production of variety i,
‾Cred
i = mean credit for variety i,
‾e
i = mean error for i.
Prior to deviation-from-mean panel model, I checked for autocorrelation for Aus, Aman, and Boro individually. For 20 observations and 1 explanatory variable, none of the crops exhibited any autocorrelation. (For Aus d= 1.411, for Aman d=1.54, for Boro d = 0.801)
Having run individual regression, the resulting transformed regressions looked like:
῀Prod
Aust = 0.0345῀Cred
Aust + ῀e
Ausit
(t=4.649,p=0.00017) (F=21.62, p=0.00019)
῀Prod
Amant = 0.2267῀Cred
Amant + ῀e
Amant
(t=4.57, p= 0.00021) (F=20.88, p=0.00023)
῀Prod
Borot = 0.527῀Cred
Amant + ῀e
Amant
(t=8.267, p= 0.000) (F=68.35, p=0.000)
During the given period a Tk 1 crore increase in disbursement of agricultural credit led to increase in Boro production by 0.527 thousand metric ton. Meanwhile, a Tk 1 crore increase in disbursement of agricultural credit translated into increase in Aman production by 0.2267 thousand metric ton.
Later I turned to see what kind of impact disasters leaves for production of rice. Here I took into account natural calamities like flood and cyclone as they inflict severe damage to crop production during the time of their occurrences. A semilogarithmic dummy regression function was constructed and the result looked like this:
lnProd
t = 9.962 + 0.000034Cred
t - 0.0625D
t
(t=242.47,p=0) (t=8.23,p=0.00) (t=-1.059, p=0.302) (F=36.11, p=0.00)
Where lnProd
t= natural log of total production of rice at t,
Cred
t = Credit disbursement at t,
D= 1 for flood/cyclone years,
=0 for calm years.
It appeared that dummy coefficient was not significant. If it were significant, we would say that rice production during flood years was 6.06% lower than that of calm years.
Then I probed on joint role of credit and fertilizer on rice production. The resulting function looked like this:
lnProd
t= 8.459 + 0.2445lnred
t- 0.0454 lnChem
t
(t=9.771, p=0.00) (t=8.04,p=0.00) (t=-0.346, p=0.732) (F= 94.23, p=0.00)
Where lnProd
t= log natural of total rice production at t,
lnCred
t = log natural of credit disbursement at t,
lnChem
t= log natural of chemical fertilizer at t.
Here coefficient of natural log of chemical fertilizer did not turn out to be significant. Model fit well. We could say a 1% increase in credit disbursement led to 0.244% rise in rice production in the given period.
Crux of the matter is disbursement of credit is vital for crop production. Disaster year presses for renewed effort and commitment in this regard. Disaster like flood often leaves some healing messages for agriculture. For instance, silt deposited along with other agricultural inputs could boost rice production in post flood years. This time we could be deprived of that as damages spring from both pandemic and lockdowns. Silver lining is that oil price is all time low and it means that irrigation cost and fertilizer production cost will be much lower than anyone can anticipate. We have to devise policies to grow more food grain to cater to the demand of people. There is evidence that past pandemic left active population severely weak. And weak population cannot fully contribute to post disaster period.
The post-pandemic world will be hungrier than ever before. Food will play a decisive role in shaping bilateral and strategic relations. We have to grow enough food so that we can win friend and allies in Africa and Asia and secure our economic interests. So we have to grow more food not just for us but for friends in near and far away continents. For that, agricultural credit should be easier to access and hassle-free. And we have to make sure that it falls into the right hands.
Key takeaway of this analysis is that this pandemic may inflict damages to crop production that may not be seen in other disaster years. Agricultural credit is quintessential to grow more crops and requires govt’s policy support. Growing enough food has also strategic benefits. While assessing policies in the time of pandemic, our policy makers should contemplate this uncharted course of food security.
