Commercialization of Sericulture Technologies and Innovations in Uganda project was part of the innovation projects which were supported by Innovation Fund in the FY2017/2018 in accordance with guidelines from H.E The President of the Republic of Uganda to support scientists to commercialize their innovations.
Since it’s inception, this project is partly supported by the Government of Uganda through The Ministry of Science, Technology and Innovations (MoSTI) and supervised by The Uganda National Council for Science and Technology (UNCST).
Sericulture: is the art and science of rearing of silkworms for the production of raw silk and its end product is silk. Silk is a natural protein fibre, some forms of which can be woven into textiles.
The protein fibre of silk is composed mainly of fibroin and produced by certain insect larvae to form cocoons. Sericulture has become an important cottage industry in the world today creating employment for millions of rural and urban people.
Sericulture is an eco-friendly agro-based labor intensive and commercially attractive economic activity, falling under cottage and small-scale sector. Sericulture enterprise in its totality is a long chain industry from mulberry cultivation to fabric making. Sericulture is the only cash crop, which provides frequent and attractive returns throughout the y
Sericulture Industry provides classified employment generational pattern of the industry into two major types:
The Sericulture Industry Value Chain Cycle (SIVCC) or Distinctive Segments (DSs) is as follows:
Stage 1: Mulberry Cultivation,
Stage 2: Construction of grainage (Silkworm egg production house),
Stage 3: Construction of Silk worm rearing houses,
Stage 4: Silkworm rearing,
Stage 5: Construction of structures for reeling based on the specifications of the reeling and re-reeling machines,
Stage 6: Installation of Reeling and other post cocoon processing equipment and training technicians on how to operate them,
Stage 7: Twisting and dying operations,
Stage 8: Silk products and silk trade of commercialization of the innovations,
Stage 9: Support Services for Silk value chain (SVC).

Increase industrialization and export Development through sustainable adoption of Sericulture technologies and innovations in Uganda.
To achieve excellence in utilization of Next Generation Research Outputs (NGRO’s) to transform Uganda’s sericulture industry from subsistence to sustainable commercial production.
The project aims at promoting the development of Silk Industry to create gainful employment and improved levels of income in Sericulture through utilization of Next Generation Sericulture Technologies, Innovations and Management Practices (NGSTIMPs). This project also aims at increasing domestic production of Silk and its by-products, thus raising rural incomes for small-holder producers and ensuring the supply of affordable silk products to Ugandan consumers and export markets.
In developing countries, agriculture and agro-based industries play a vital role in the improvement of rural economy. Uganda is endowed with abundant natural resources and thus scientific agricultural development can contribute to the gross economic product to a greater extent. The limited availability of land, the limited cash returns and agriculture being confined to one or two seasons in a year have created the need to look for supporting rural industries such as Sericulture. Among the agro-based rural industries, sericulture occupies an enviable point of view of providing gainful employment and additional income.
Sericulture, the process of silk production, is an-agro based industry which can play an eminent role in the rural economy of Uganda. Sericulture can play a vital role in the Ugandan economy in transfer of wealth from the richer to the poorer sections of the society. The affluent class mostly consumes silk products and the value of the final fabric is distributed among all the intermediaries such as farmers, reelers, twisters, weavers and traders. Sericulture has the potential of becoming one of the most important rural industries due to certain inherent advantages like minimum gestation period constant and periodic returns throughout the year.
In commercial production, an acre of Sericulture Industry Value Chain offers a minimum of six (6) (1 for mulberry cultivation, 2 in Silkworm rearing, 1 in post cocoon technology, 1 in making silk fabric and 1 in Marketing of the silk fabric) job opportunities. At an average of UGX: 300,000 per worker per month, each worker in sericulture industry will earn UGX: 3,600,000 from one acre of cultivated land by selling silk yarn. Going up the value chain; each kilogram of silk yarn produces 9.3 meters of pure silk cloth (grey fabric) whose price ranges from USD: 10 to about USD: 20 per meter. 180 kilograms of yarn can produce 1,674 meters which at a rate of USD: 10/meter results into USD: 16,740. A farmer when provided with a handloom for weaving cloth can thus earn USD: 16,740 equivalent to UGX: 62,775,000 from one acre by selling silk cloth but can even earn more if gets better price for the cloth especially if there is a mixture of mulberry yarn with yarn/threads from wild silk.
In summary an adequately trained and supported farmer can approximately earn UGX: 8 million from selling mulberry leaves and cuttings, UGX: 14 million from selling cocoons, UGX: 34 million selling yarn and UGX: 63 million from selling fabric all from having one acre of mulberry, a rearing house, a pedal/hand-reeling machine and a hand-loom. The benefit can be higher if tailored clothes are sold.
Cost benefit analysis of leaf and cocoon production from one acre per year
Higher productivity and consequently higher returns are the guiding factors for any venture. Investing in Sericulture has long been known for its higher returns as compared to other cash crops such as coffee, cotton, sugar cane, tea and tobacco.

Mulberry is a perennial crop. It contributes to soil conservation and provides green cover Waste from silkworm rearing, is recyclable for agricultural use Dried mulberry twigs and branches can be used as fuel. Mulberry can be cultivated in areas of often unused land, e.g. hill slopes and watersheds.
Total investment over a period of five years is 775 billion Ugandan Shillings including; establishment of Sericulture Research and Technology Transfer Centers in Western, Central, Eastern and Northern Uganda. Returns will be more than one Trillion shillings per year. If Uganda can master silk fabric technology and tailoring, the benefits will be more than 5 Trillion shillings over a period of five years and there after UGX: 1.322 Trillion annually. Full time employment worth UGX: 105 Billion annually will be created and over 50.000 casual jobs worth UGX: 200 Billion annually.
Employment on both on and off-farm activities. 60% of those employed in sericulture are women. Rural economies will be maintained and strengthened. This is because more than 80% of the gross value of silk fabrics returns to the local area of production (to cocoon growers, reelers, twisters and weavers).

Our approach is guided by the baseline and feasibility study that we conducted which identified 10 entry districts and 40 other districts for up-scaling the project. Eventually the project will cover the entire country. As an entry point, we normally request to use public land or land that belongs to a given community and or church or land belonging to a religious community.
This is to ensure that there are minimum volumes required to sustain extension and agro-processing facilities during project commercialization. Using this model, activities are sustained in the absence of funding from government and or external funding. It is run on a business model and it is profit-oriented. It is a model which combines nucleus farmer approach and commercial farming approaches.
Nucleus farm model: is a large farm unit (plantation, large-scale farm) which guarantees a certain minimum provision of raw material for a large-scale processing plant or other downstream aggregation use, while the other part of the raw material is procured from smaller farmers who are linked through out-grower arrangements to the nucleus.
Nucleus model combines a commercial farm with a program that works with nearby farmers, called out-growers, allowing TRIDI greater control over its product while still leaving room to foster and train local small-scale farmers in Sericulture production. The goal is to establish a production hubs of Sericulture Industries benefiting both TRIDI and local farmers.
A nucleus farmer under this model is an exemplary farmer at village level, who has adopted best practices of farming and acts a model where farmers access technology and common user facilities.
Using this arrangement, the project avoids organizing the procurement from a large number of farmers and this means reducing the associated high costs. In addition, the project avoids risk in contract farming which is side-selling, where farmers sell to other buyers for various reasons – better price, avoidance of repayment of credits, better (i.e. more rapid) payment conditions, and social obligations. In addition, the reliance on a smaller region for procurement, while reducing transport and communication costs, increases risks from crop failures due to local adverse weather or pest events, more so if farmers do not have means such as irrigation, knowledge or to pesticides to control at least a part of these production risks. This model avoids pure large-scale farming, by requiring fewer land acquisitions, distributing wealth more equitably, disturb rural social structures less radically, and have a higher support from governments. Compared to pure contract farming, procurement is less risky and internal transaction costs are lower. Using this model, TRIDI enters into a memorandum of understanding with the land owner who provides the land and TRIDI develops the land and is responsible for the implementation and management of all the activities. The profits are determined in accordance to the overall contribution made by each party (one party being the land owner and the other being TRIDI or as determined by change of share capital from time to time).
To enhance commercial production, there has been mulberry plantation establishment, management and production at 25 stations in 18 districts i.e. Sheema, Mbarara, Kiruhura, Bulambuli, Kamuli, Mubende, Mukono, Iganga, Luweero, Kayunga, Nakaseke, Kween, Bukedea, Zombo, Nwoya, Buikwe, Pallisa, Busia on a total of 627.92 acres. The project will expand to cover 50 districs and potential sites are to be established in Lira, Amolatar, and Otuke districts.
Silkworm rearing has so far been carried out in 6 districts i.e. Sheema, Mukono, Kamuli, Pallisa, Iganga and Kayunga.
