Sericulture in Turkey is; performed where the agricultural lands are not suitable for other

agricultural activities,

done in mountanious, limited, unproductive and slantingagricultural areas,

performed in small scale farms

providing alternative source for livelihood income

performed by families with lower income scales

economically performed only in spring

Sericulture in Turkey is; Employing family labor in 1709 households in 2014

Still an economical activity for the producers who have lowerincomes

14-fold added value is provided as a result of transformation offresh cocoon into silk carpet

Turkey is one of the few countries that produce silkworm eggsfree from polarin disease (sanitary) and has its own geneticresources, and meet the big part of the EU’s need of silkwormeggs.

Moreover sericulture has an important place for Turkey interms of protecting cultural heritage and genetic resources.

The main factors that leads to significant decrease on production andnumber of households involved in sericulture :

decreased prices in domestic markets due to the lower import prices

The more revenue of alternative agricultural activities than that ofsericulture

The structural problems of the farms

The changes and interactions in social structure

The excessive use of agricultural chemicals

Industrialization

Urbanization and immigration

Most of the cocoon produced in Turkey processed domestically andsilk is manufactured

Raw silk thread production began in the facility that was establishedby Kozabirlik (Cocoon Union) in Eskişehir in 2009 in order to drawfilaments from silkworm cocoons.

However, the production was ceased for a while in February of 2012because of the decreasing prices towards the end of 2011

Moreover, to prevent the losses stemmed from dehiscence in 2008, adehiscence facility was established to disseminate the dehiscent bugsto the producers in the region

The only organization in sericultureis Cocoon Union (Kozabirlik) that isactive in sericulture and marketingthe products.

Kozabirlik is an Agricultural SalesCooperative and the sole purchaser(monopsony) of the fresh cocoonsproduced domestically. from CocoonUnion.

22.07.2015 10

After 1995, with the private sectorwithdrawing from the market,Kozabirlik purchasing share hasreached to 100 percent.

All the silkworm seed to feed is met

Page 11: SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND ... Taskaya Top pres_.pdf · SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND POLICIES. Berrin TA. Ş. KAYA TOP,

Consumption The dry cocoon is processed mostly by Kozabirlik (Cocoon Producers

Union) and transformed to silk, drawing filaments from annuallyaverage of 50 tons dry cocoon.

The significant proportion of imported raw silk and silk thread is usedin carpet sector.

Because of the very high prices of silk carpet, nearly all of carpets areexported. However, 50 tons of silk textile products made by raw silk areconsumed domestically.

22.07.2015 11

Taking into account marketconditions, nearly average of100 tons of silk thread importedannualy is used by carpetmanufacturers

Foreign Trade of Turkey

The fresh silk cocoon is not subject to trade in Turkey but drycocoon, raw silk and silk thread.

The products (seed, dry cocoon, raw silk) of sericulture has zerotariff rate and there is no subsidy allocated for their exportation

22.07.2015 12

Page 13: SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND ... Taskaya Top pres_.pdf · SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND POLICIES. Berrin TA. Ş. KAYA TOP,

Import Turkey is dependent on foreign

countries and is net importer forraw silk. Because of;Supply of fresh cocoon not

meeting the demand, Turkey not having modern

drawing facilities for processingof cocoons produceddomestically,

Silk production costs being veryhigh

In 2013, Turkey imported 58.3 tonsraw silk and 63.2 tons silk threadand value of this importation was6.3 million dollars

Export Since there is no modern silk flatur

machine and the cocon drawing capacityis limited, the big part of cocoons areexported. Therefore, Turkey is a netexporter of dry cocoon.

Average 35 tons of dry cocoon wereexported annually between 2002-2013 andimportant decreases occured in the yearsof crisis since the product elasticity wasvery high.

Turkish silk thread exportation wasdecreased by 92.8 percent and theexportation value of 1.65 million dollarsin 2000 decreased to 445 thosand dollarsin 2013. In line with exportation decrease,thread importation increased by 8-fold

Nearly all the silk carpets produced areexported and the value of exportation ofsilk carpet is annually some 100 milliondollars

Sericulture policies in TurkeySince 2002, sericulture have been subsidized due to:

Encourage sericulture production,

Prevent immigration from rural to cities,

Provide livelihood income for rural people

Conservation of traditional and cultural activity

Conservation of genetic resources,

Promotion of Rural Development

Page 16: SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND ... Taskaya Top pres_.pdf · SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND POLICIES. Berrin TA. Ş. KAYA TOP,

Subsidy is given per kg of product to the producers who sell theirproduct to the Kozabirlik. In addition to the subsidy, the purchasingprice per kg of product is granted to the farmers.

In 2014, -silkworm seeds which have been distributed without anycharge- government gave 10 € per box subsidy to KOZABİRLİK and10 € per box to producers for fresh cocoon.

Page 17: SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND ... Taskaya Top pres_.pdf · SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND POLICIES. Berrin TA. Ş. KAYA TOP,

The amount of support is of big importance for the fresh cocoonproducers

Because, sericulture farms are located in mountanious areas in theabsence of alternative sources of income

74.9 percent of the producers interviewed stated that their mainincome sources was sericulture

Therefore, in order to provide livelihood income for people involvedin sericulture and to preserve genetic resources taking into accountthe importance of traditional and cultural dimensions by the waypreventing sericulture enterprises from expiring in addition to this toenhance rural development efforts by supports seems to be veryimportant and compulsory.

Page 18: SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND ... Taskaya Top pres_.pdf · SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND POLICIES. Berrin TA. Ş. KAYA TOP,

However, 72 percent of fresh cocoon producers interviewed statedthat the subsidy amount was insufficient.

On the other hand, producers asks for nurture house supports.

Page 19: SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND ... Taskaya Top pres_.pdf · SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND POLICIES. Berrin TA. Ş. KAYA TOP,

The lack of any precondition such as least production amount,etc. for producers to benefit from support ensure thesustainability of the production but do not increase the yieldsand production.

Because, after 2002, although the decrease in sericultureproduction was stopped due to subsidies, the productionamount in 1990s can not been achieved.

RESEARCH FINDINGS

22.07.2015 20

The findings that are obtained from the surveys conductedwith fresh cocoon producers in the farms engaged insericulture are given in this part of the study.

Page 21: SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND ... Taskaya Top pres_.pdf · SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND POLICIES. Berrin TA. Ş. KAYA TOP,

RESEARCH FINDINGS The work force has gradually decreased

and the average age of producers hasincreased

83.8 percent of fresh cocoon producersin the farms engaged in sericulture areover 40 and 20.3 percent over 65.

This shows that the silkworm producerswill become more aged population inthe future period. Therefore it isestimated that there will be ansignificant decline in the number ofhouseholds that are engaged insericulture.

RESEARCH FINDINGS

22.07.2015 22

71,4 percent of household workforce insericulture farms are actively working inproduction

20.3 percent of the farms are notinvolved in any agricultural activitybeside sericulture

79.7 percent of the farms produce plantsand/or livestock products.

However, the income of vegetative andlivestock production are the main sourceof income only in a little part of farms.

74.9 percent of the producers interviewed stated that their main incomesources was sericulture

Average annual income of the farms 3625 Euro

Average annual income of farms from sericulture 645 Euro

Share of income collected from sericulture under agriculture 54.7 %

Share of sericultural income under total agricultural revenue 17.8 %

Sericulture is an important income source for the small family farms

Since the annual total income of the producers that are engaged insericulture is very lower than the ones that make other agriculturalactivites it is obvious that the farms studied need certainly the income ofsericulture.

Gross Producion Value (GPV) per farm in 2013

hybrid cocoon producing farm 153 Euro breeding cocoon producing farm 400 Euro

However, as all the producers who produce silkworms get thegovernment subsidy, the annual GPV is 802 euro in breeding farms and605 in hybrid ones.

According to the study findings, excluding fresh cocoon and seed, grossmargin per farm is -11.72 euro/year, otherwise 226.96 euro/year.

The inputs such as seeds and formaldehyde etc. are met for free byKozabirlik (Cocoon Union), the production cost of fresh cocoon isvery low.

The fresh cocoon cost is calculated as all expenses of sericultureactivity is divided into annual production.

Thus, 1 kg fresh cocoon cost is 2.67 euro in hybrid farms and 3.36 inbreeding farms and 2.72 euro in all the farms.

It is determined that mulberry treesin the farms studied were mostly(54.5 percent) scattered and bordertress. This creates hardness fortransporting leaves.

22.07.2015 27

Nurturing Conditions

The mulberry trees used in nurturein Turkey are generally grown inmountanious villages, sides of roads,the areas which is free fromagricultural chemicals. Therefore,sericulture is partly or wholly anorganic agricultural activity.

Page 28: SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND ... Taskaya Top pres_.pdf · SERICULTURE IN TURKEY: CURRENT SITUATION, CONSTRAINTS AND POLICIES. Berrin TA. Ş. KAYA TOP,

The production in Turkey is mademostly in traditional methods and thefarms do not have proper facilities.

63.3 percent of the producersinterviewed used the part of their houseas nurture facility and 30 percent ofthem used seperate nurture house.

Producers both live a social life andand produce in a part of their houses.3.9 percent of them use the barn asnurture house which has thecontamination risk and do not haveproper physical conditions.

Depending on adverse conditions of production, –in survey year- 47.8percent of producers stated that they met silkworm disease and incurredyield loss.

In the farms that faced with disease, yield per box was decreased by18.96 percent from average 28.51 kg/box to 23.10 kg/box.

According to the fresh cocoon producers interviewed the major reasonsquiting sericulture are:

The low price of cocoons : The lowness of cocoon prices cause toproducers to rip of their mulberry tress and tend towards the moregainful agriculturel activites

lack of work force: The other most important factor for quitingsericulture is the lack of work force for especially breeding silkwarmfarmers. Although it creates income in a short period, the youngpopulation do not continue sericulture and tend towards otherprofessions because of its hardness of working conditions and beinglabor intensive

The problems of procurement mulberry leaves and the more profitability of other agricultural activities

22.07.2015 31

The commitment of producers to sericulture and producers havingnecessary traditional information about it, producers being able toproduce healthy silkworm eggs, the existence of the regions that are notpolluted by pesticides and industry free, not requiring much expenses butproducers workforce, good quality, having silk carpet trademark and thesector organizing in Cocoon Union which is the sole farmer organizationon sericulture in Turkey are advantageous aspects to sustain sericulture

However, insufficient workforce due to the migration of youngpopulation from villages to cities with indutrialization, insufficiency ofthe number of mulberry gardens and trees and the production being madeonce a year so nurture performing in the houses are the most importantconstrainst for increasing production.

Constraints and proposals

Producers not having the special nurture houses and gaining lowincomes due to low production, the yield losses due to the continuedtraditional production methods, the negative effect of importation dueto competition for lower prices and zero tariff rate for silk importationaffect production increase.

The main aim in the sector is to increase production. Therefore, it isrequired to create strategies directed to increase production andconsistent price policies. However, creating financial funds for nurturehouses and mulberry gardens and giving information about currentrural development subsidies are other important issues.

Although there are various credits for agriculture in Turkey, these creditsgenerally comprises for postharvest phases. The current production will beprotected if the long-term credits are provided for the construction ofnurture places.

To increase quality and productivity;

• the use of new technologies in production,• modernization of nurture material,• Promotion of R&D activities,

Constraints and proposals

• increasing corporating possibilitieswith international institutes anduniversities are required.

Since there is an increasing demand for organic and ecological productsdue to awareness of conscious consumers to these products in the worldand Turkey, organic agriculture is developed. Therefore sericulture as thesecond agricultural activity should be promoted in the organic agriculturalareas. This potential should not be lost while such current sericulture isgoing on.

For silk carpet sector subsidies should be provided to compete withinternational markets, certification should be generalized in carpetproduction. New employment possibilities and income sources will becreated by producing new alternative products beside the silk carpet.
