3. Introduction
Solid fuels are source of energy for cooking purposes to almost half of the world’s population.
Traditional ways of cooking using these fuels result to incomplete combustion which releases greenhouse gases and other incomplete combustion products.
These products have been found to be harmful to both human health and climate.
Indoor air pollution in Malawi is estimated to be around 226 μg/m3 (Fullerton et al, 2009). acceptable level by WHO is 25 μg/m3.
Deforestation in Malawi is increasing at a higher rate which is estimated at 3.2% (Malinski, 2008)
Leading to scarcity of firewood
Different organisations and other development agents are promoting the adoption of improved cookstoves (ICS) in order to address these problems.
Chitetezo Mbaula: Most widely promoted portable efficient cookstove in Malawi as it is more affordable to poor rural household than other stoves
Comparatively easily made locally using locally available resources

4. PROBLEM STATEMENT
Five years down the line since NCSC was created, only 879,711 improved cookstoves have been reported to be produced (energypedia, 2018).
Yet we have two years only to reach the adoption target of 2 Mio
Other studies have found that ownership of improved cookstoves in Malawi are strongly influence by the availability (Meyer, 2015; HEDON, 2014).
It is against this background that the need to explore effective ways of producing improved cookstoves should not be undermined.

5. PROBLEM STATEMENT CONT’D
The GoM set a policy of strengthening the capacity of local producers.
It is envisaged that such developments would increase the production levels thereby meeting the demand for the stoves.
However, such efforts would be undermined by inefficiency of how the resources are used in the production process.
Efficiency is also very crucial in sectors characterised by resource constraints.
Mpofu, (2015) reported that Chitetezo Mbaula production groups face various challenges among which include lack of inputs.
It is therefore imperative to conduct a study analysing the production efficiency of Chitetezo Mbaula cookstove producers
This study seeks to answer the following research questions:
Are Chitetezo Mbaula production groups in Malawi technically, allocative and cost efficient?
How does institution and producer socio-economic characteristics affect the technical, allocative and cost efficiency levels of Chitetezo Mbaula production groups?
Cook Stoves Road Map is strengthening the capacity of local producers

6. OBJECTIVES
Main Objective
To analyse the production efficiency of Chitetezo Mbaula production groups in Malawi
Specific Objectives
To analyse the technical, allocative and cost efficiencies of Chitetezo Mbaula cookstove production groups.
To determine the factors that the influence technical, allocative and cost efficiency levels of Chitetezo Mbaula cookstove production groups.

7. HYPOTHESES
Chitetezo Mbaula production groups in Malawi are technically, allocative and cost inefficient.
Socio-economic, institutional and demographic factors do not influence the technical, allocative and cost efficiencies of Chitetezo Mbaula production groups in Malawi.

8. STUDY JUSTIFICATION
Guidance on what level of inputs combination ensures optimum production.
Advance the understanding of producer differences and prospects to improve producer efficiency in using the resources of production.
Help to pinpoint prospects and limitations that can be used as input information to devise strategies that promote ICS production.
Developing and restructuring interventions for improved cookstove production

9. METHODOLOGY
Study Area
Central region: Dedza, Kasungu and Salima districts
Southern region: Nsanje, Balaka, and Mulanje districts
Purposively chosen as they have considerable amount of Chitetezo Mbaula producers to suffice the required sample.

10. Where Z =1.96 for 95% CI, P=0.5, q=1-p, e=0.09 and N=217
METHODOLOGY CONT’D
Sampling Technique
Cluster sampling technique to draw the sample of producers to be studied.
Cluster- districts
Using a simple random sampling (SRS) method adopted from Kothari, (2004):
Where Z =1.96 for 95% CI, P=0.5, q=1-p, e=0.09 and N=217
n=67
Considering a Design effect of 2 and 10% increase for non-respondents: n=150
P is the population probability
e is the margin of error

Proportional to population size (PPS) technique has been used to determine the sample size from each district

12. DATA ANALYTICAL TECHNIQUES
