INTRODUCTION

Malawi is a small country of 12.3 million hectares with a population of 10 million, 85% of which live in rural areas where subsistence farming is the main way of earning a living. Malawi's productive capacity is limited and concentrated within a few sectors.  Agriculture is the largest economic sector, while the industrial base remains limited and consists mainly of agro-processing industries.

 

Agriculture accounts for one-third of GDP, 90 per cent of export earnings, and three-quarters of total employment. The smallholder sub-sector occupies 1.8 million hectares, over one-half of the households have less than one hectare, and one-quarter less than 0.5 hectare. Only one-third of these farmers use fertiliser, most use less prolific local seed, and productivity among smallholder farmers is generally low. The majority of households are unable to meet their food requirements.  Currently the non-formal sector employs 85.5 per cent of the labour force, out of which 81 per cent is in smallholder agriculture and only 4.6 per cent in non-agriculture related self-employment. Maize is the dominant subsistence crop and covers 80 per cent of all cultivated land (UNDP Malawi Profile, 2001).  In addition to maize other food crops include roots and tubers (cassava, potatoes), grains and legumes (rice sorghum, millets, beans, cowpeas, Soya, Ground nuts) fruits and vegetables (mangoes, bananas, oranges, avocados, peaches, tomatoes and many others).  Most of these crops are produced on small scale and in specific areas of the country.

 

Bunda College of Agriculture was established in the late 1960s as an institution of higher learning for agricultural officers.  There are several departments at the college which tackle post harvest issues, and these are  Home Economics and Human Nutrition , Agricultural engineering and Animal science.  Several courses are offered in these departments that address post harvest issues.  In addition several research projects in the post harvest sector are underway.   

 

Food production and post harvest issues in Malawi

The post harvest sector in Malawi is very crucial in ensuring food security in Malawi where over 90% percent of the food supply is produced in the rural areas of the country under the rain fed system.  Such that there is one major harvest in the year which has to cater for the food needs of both the urban and rural areas through out the year.

 

There are several challenges being faced in the post harvest sector in Malawi.  Although few detailed studies on post harvest loss have been conducted,  about 30% loss in hybrid maize stored for 8 months has been reported (Phiri et al 1997).  The loss in fruits  and vegetables may be as high as 50% during the peak season.  These losses are mainly due to lack of proper transportation and storage structures.

 

Post harvest techniques are crucial to the welfare of poor rural people because of their effects on income distribution and employment in addition to decreasing food losses (Greeley 1990).  Small holder farmers producing the bulk of the food crops sell them in the raw form at very low prices.  However provided appropriate technology farmers would be able to increase their income from their products as well as create employment within their communities.

 

Post harvest programmes/initiatives at Bunda College of Agriculture

As an agricultural institution of higher learning Bunda College is involved in teaching, research and consultancy.  There are several projects dealing with post harvest issues which are underway at the college. 

 

Legumes and oil seed  processing

Soya beans

The crop has been produced for  a long time in Malawi as early as the 70s, however it was towards the end of the 1980’s that the production of Soya beans picked up.  In 1989 Soya bean was substituted for common beans and ground nuts in Likuni Phala (Ministry of Health 1992).  Likuni phala is the flour that is used as a weaning food mainly comprising of maize and legumes in differing proportions.  Despite being widely incorporated in Likuni Phala, utilization of Soya beans has been limited  in the basic diet of most Malawians.  Attempts have been made to promote the utilization of Soya beans at household level by various interests groups including UNICEF, Ministry of Agriculture, University of Malawi (Bunda College of Agriculture) and the Ministry of Health (FAO/MOALD 1997).  Much of this promotional work was targeted at small holder farmers who are the major producers  of Soya beans.  These farmers were growing Soya beans as cash crop.  However the majority of the people in the rural areas are at an increased risk in terms of Protein energy malnutrition.  The drive behind this promotional efforts was the potential of Soya beans in improving the nutrient value of the predominantly maize based Malawian diet.  Students are in taught the processing of Soya beans into products that can be easily incorporated in the Malawian diet.  In addition several non governmental organizations dealing with food security send their extension workers for training in Soya bean processing.    

 

In addition UNIDO through the SEPIA project is also promoting the utilisation of Soya beans by training Micro Small and Medium Scale enterprises in soya bean processing.  These MSMEs have been trained in Soya bean processing and are awaiting training in food safety and quality assurance.

 

Sun Flower

Bunda College in corroboration with UNICEF embarked on promotion of a sunflower oil extractor among women groups in rural areas.    Women groups operated a ram press as an income generating activity but due to stiff competition in the procurement of raw materials and selling of the oil the project could not be sustainable (Chiyembekeza 1996).

 

Fruit vegetables processing

Despite the fact that there is a lot of spoilage of fruits and vegetables during  peak production minimal work has been done to harness this opportunity.  However the Agricultural Engineering department at Bunda has developed a Ram juice extractor for citrus fruits and pineapples.  The technology is currently being promoted the Malawi Industrial Research and Technology development Centre (MIRTDC). 

 

Charcoal and brick coolers have been developed to address the need for storage of fruits and vegetables.  This technology assist in increasing the storage life of fresh fruits vegetables.  In addition a solar drier has been tried for drying vegetables.  Although dried fruits are not a common item on the market there is potential for drying mangoes and bananas which are usually wasted in peak months.

 

Roots and Tubers

Through the Small grant programme funded by IITA and Sarrnet, Bunda College is involved post harvest research for cassava.  The project is aimed at promoting commercial processing of cassava.  The work include a consumer study, proximate analysis, shelf life studies and preference.

 

Currently shelf life study of the cassava flour and the secondary raw materials is underway.   Information on the shelf life of cassava products  will assist the interested processors in the production and marketing of their product..  Currently one of the main grain millers has started buying dried cassava chips from farmers and processing into flour which has just been launched on the market.

 

Food safety and quality

Food safety and quality issues are now gaining more attention among consumers.  Therefore students are exposed to the prevailing food safety issues in the country.  Information on the status of food safety and quality in Malawi is very scanty.  Concerns on food safety and quality are not properly documented at all.  

 

Challenges faced by post harvest initiatives at Bunda College of Agriculture

a.         The Master of Science degree programme in Food Science and Human Nutrition at Bunda is facing high financial difficulties in that most potential students are unable to source funding for their studies.  Funding for research in the area of food processing is minimal because most of the funding organisations prefers other areas directed at increasing food production other than post harvest issues. 

b.         Some of the technologies that have been developed or adopted at Bunda College of Agriculture have not successfully been adopted by the targeted end users.  This apparent failure in adoption is partially due to:

i.                     Promotion campaigns for these technologies were dependent on funding of a particular project

ii.                   Some of the targeted end users lack financial resources to purchase of appropriate machines

c.                   Partnership between researchers at the College and the industry has

been a problem.  At the moment there is one grain miller who is working with us on cassava processing.

d.                  Access to information on Post harvest issues is limited.  New developments in the sector are difficult to access due to limited financial resources.

e.         While there are several projects taking place at the college there is limited space for work.  The design and stocking of sheds or laboratories at the college does not accommodate post harvest work properly.  There is need for a pilot plant or shed where students and staff can work properly and interested MSMEs cn test new technologies.
