Agricultural Survey [ag/oth]
In recent past, three survey projects had been conducted through National Survey of Agricultural Exportable crop Commodities (NSAEC). The survey projects include: Pilot test 2002/2003, others 2004/2005 and 2005/2006.
The projects were jointly carried out by four federal agencies namely: National Bureau of Statistics (NBS), Central Bank of Nigeria (CBN), Federal Ministry of Agriculture & Rural Development (FMA&RD) and Federal Ministry of Commerce (FMC).
Obviously, the results obtained from these joint projects would add value to agricultural production in the country. It is believed that the survey results would give both government and non governmental agencies ample opportunity to address the ugly situation of the past years.
The survey covered the following fourteen crops: Cashew, Cocoa, Coffee, Cotton, Garlic, and Ginger, Groundnut, Gun Arabic, Oil palm, Rubber, Sesame seed, Sheanuts, Sugar cane and Tea.
This report is based on the 2005/06 survey result which is the third edition of its series and the most recent conclusive project.
In the recent past, three survey projects had been conducted by the Technical Committee of the Consultative Committee on Agricultural Export Commodities Statistics (CCAECS). The survey projects include: Pilot test 2002/2003, 2004/2005 and 2005/2006. The projects were jointly carried out by four federal agencies namely: National Bureau of Statistics (NBS), Central Bank of Nigeria (CBN), Federal Ministry of Agriculture & Rural Development (FMA&RD) and Federal Ministry of Commerce (FMC).
Obviously, the results obtained from these joint projects would add value to agricultural production in the country. It is believed that the survey results would give both government and non-governmental agencies ample opportunity to address the ugly situation of dearth of reliable statistical data on export crops.
The survey covered the following fourteen crops: Cashew, Cocoa, Coffee, Cotton, Garlic, Ginger, Groundnut, Gum Arabic, Oil palm, Rubber, Sesame seed, Sheanuts, Sugar cane and Tea.
This report is based on the 2005/06 survey result which is the third edition of the series and the most recent conclusive project.
The major objectives of the survey include:
i. To ascertain the spread of the cultivation of each of the fourteen export crops within Nigeria in terms of area cultivated by state.
ii. To provide a national baseline data on agricultural export commodities.
iii. To provide structural data on agricultural export commodities in Nigeria.
iv. To obtain socio-economic data and demographic characteristics of holders within households.
v. To provide production estimates at national and state levels.

Sampling
The first frame was the list of 774 LGAs nationwide. The second frame was the list of EAs demarcated by the National Population Commission during the 1991 population census. 192 LGAs were selected nationwide. A 2-stage sample design was employed.
In the first stage,10 EAs were systematically selected from each sampled LGA. Of the expected 1,920 EAs, only 1,855 were found to have export crops and were eventually studied.
In the second stage,10 export crop farming housing units were systematically selected from each sampled EA (provided there were more than 10 farming housing units in the EA). Where there were 10 or less farming housing units, no selection was required and all available housing units were studied.
Out of the 18,550 export crop farming housing units expected to be covered, 16,310 were canvassed.
On national basis, 100 percent response rate was acheived at LGA level and 96.61 percent at EA level while 87.92 percent was acheived at export crop farming housing units level.
The variable (rf ) raising factor is computed and attached to the data file.
The formula adopted in calculating the design weights for the survey data (sample results) were as follows:
(i) The probability of selecting an EA within a state was obtained by dividing the total number of EAs sampled in a state by total number of EAs in that particular state. Let this be represented by fj. That is,
fj = Total Number of EAs sampled in a state / Total Number of EAs in that particular state
(ii) Likewise, the probability of selecting an housing unit (HU) within an EA was obtained by dividing the total number of housing units selected in an EA by the total number of housing units (HUs) listed in that particular EA. Let this be represented by fk. That is,
fk = Total Number of HUs selected in an EA / Total Number of HUs listed in that particular EA
Mathematically,
Design weight = (Total number of EAs in a state / Total number of EAs sampled in that particular state) X ( Total Number of HUs listed in an EA / Total Number of HUs selected in that particular EA)
