3. BACKGROUND
Globally, biomass fuels are the most commonly used fuels for cooking and heating
In Malawi, 95% of the households use biomass while fuel wood use accounts for 84% (NSO, 2012).
Because 70% of households in Malawi have no access to non-biomass fuels (Stanturf et al., 2011).
Even households with electricity still depend on wood fuels because of high electricity tariffs and cost of appliances (Jumbe and Angerson, 2011).
The dependence on biomass is associated with environmental & health- related problems such as Household Air Pollution, carbon emissions and deforestation (Sagbo, 2014).

4. BACKGROUND
In Malawi, deforestation rate is estimated at 3.2 percent which is among the highest in Africa (Malakini et al., 2014).
Burning of biomass for cooking and heating on traditional three-stone firewood stove is often associated with greenhouse gas emissions (Wanjohi and Smyser, 2013).
Soot from burning biomass fuels is considered the second largest contributor to anthropogenic climate change (Sagbo, 2014).
Household air pollution is reported the second most vital risk factor after childhood underweight in sub-Saharan Africa with 13,000 annual deaths estimated in Malawi alone (Lim et al., 2012).

5. BACKGROUND
To reduce the negative health and environmental effects associated with cooking with biomass fuels, GoM & NGOs have been promoting the use of ICS.
Aiming at distribute two million ICS in households by 2020 (Jagger and Jumbe, ).
However, past research has shown that ICS adoption has been low and slow (see Meyer et al. (2015), Jeuland et al. (2013) and Jueland et al. (2015)).
This raises the questions as to whether consumer preferences and WTP for ICS are considered when promoting such ICS.

6. BACKGROUND
In addition, others claim that ICS technologies are not widely adopted because they do not conform to user preferences and local cooking environment (Lewis and Pattanayak, 2012 & Whittington et al., 2012).
This study was therefore designed to assess the consumer choice and willingness to pay for Improved Cookstoves in Malawi using Chiradzulu as a Case Study.
Chiradzulu District was purposefully chosen as most households have never used ICS before and that there are presently no stoves program in the district
A thorough understanding of consumer preferences and WTP for ICS is critical for the success of interventions aimed at promoting ICS.

7. Study Objectives
Specifically, the study aimed at achieving the following two objectives:
To determine factors that influence household choice of ICS in the study area
To determine willingness to pay for ICS and its influencing factors
The findings of this study are crucial as they inform the design and implementation of appropriate strategies to enhance wider adoption of ICS in Malawi.

8. METHODOLOGY
We used a Contingent Evaluation method as a stated preference technique which involves posing hypothetical questions to respondents.
During the interview;
Primary cook was presented with pictures of Chitetezo Mbaula, TLC Rocket Stove and Portable Rocket Stove along with the description of their associated features and attributes.
Primary cook was asked to choose a preferred stove among the three stoves.
The respondent was then told of the stove`s prevailing market prices of the preferred stove and asked to state his/her WTP.
This information was used along with other socioeconomic data that were collected to conduct the analysis

13. Determinants of ICS Choice
MLM results revealed that
Chitetezo Mbaula is the most preferred ICS seconded by TLC Rocket Stove and Portable Rocket Stove.
Choice of Chitetedzo mbaula is influenced by
Distance to firewood source from home,
firewood collection frequency per week,
number of adult females,
primary cook education level,
household head age,
under-five children ratio

14. Determinants of ICS Choice
MLM results revealed that
c) Choice of TLC Rocket Stove is influenced by
Value of household assets
Own source of firewood
Choice of Portable Rocket Stove is influenced by monthly income

15. WTP ESTIMATES Mean WTP estimates
Chitetezo Mbaula MK1586 ($2.22)
TLC Rocket Stove MK2838 ($3.98)
Portable Rocket Stove MK12032 ($16.87)
Estimated mean WTP value for Chitetezo Mbaula is far above the presented market price of the stove MK650 ($0.9)
Estimated mean WTP for TLC Rocket stove MK2838 ($3.98) is slightly lower than the presented TLC Rocket Stove market price (MK3000 or $4).
Estimated mean WTP for Portable Rocket Stove is slightly higher than its market price by MK20.34 ($0.03).

16. Determinants of WTP for ICS
WTP for Chitetezo Mbaula was influenced by;
household head sex,
total time spent collecting firewood,
number of adult female members in the households
However, number of firewood collection helpers in the household has a negative effect on WTP.
TLC Rocket Stove`s WTP was ;
Positively influenced by firewood source distance from home
But negatively influenced by age of the primary cooks.
WTP for Portable Rocket Stove was;
Positively influenced by firewood source distance from home.
But negatively influenced by total time spent collecting firewood

17. Policy Implications/ Messages
From our study, there are 4 key findings that have important implications for the Government initiative to distribute 2 million cookstoves by 2020
The study has established that household income increases the probability of choosing ICS in Chiradzulu District. Wider adoption of ICS will therefore require complementary interventions that will raise incomes of households (e.g., income generating activities).
The study further establishes that household socioeconomic and demographic differences play an important role in determining choice and WTP for ICS. It is therefore imperative that the dissemination of the ICS should be complemented by consider civic education on benefits of using ICS prior to the distribution.

18. Policy Implications/ Messages
GOOD NEWS is that there high willingness among households to pay above the market price of the ICS. This offers hope for the sustainability of the program. This calls for intensifying training of local artisans/community groups on stove production to ensure the sustained availability/supply of cookstoves in the areas.
We also found that distance to firewood source and total time taken to collect firewood increases the WTP for ICS. This again is GOOD NEWS because it shows that ICS are technologies most appropriate in areas with serious firewood scarcity like Chiradzulu District. This calls for the need to extend the current ICS distribution efforts to Chiradzulu and other districts that have serious.

20. Way Forward
There are some areas that we further conduct research, both from the SUPPLY SIDE and DEMAND SIDE
SUPPLY SIDE: We will conduct research to analyse the production efficiencies of improved cookstoves and its determinants. (Emmanual Tolani)
DEMAND SIDE: We want to investigate factors that influence adoption/disadoption and sustained use of improved cookstoves (Christopher Chikowi)
