Abstract [en]

This study is based on the results from fieldwork conducted in November of 2014 in

the Gasabo and Kamonyi districts of Rwanda and aims to provide a cross-sectional

insight into the potential of optimized cookstove technology for rural Rwandan

households. The economic benefits of a transition into more sustainable cookstove

practices are recognized, by examining links between farming structures, waste

management and energy use. Rwanda confronts many challenges in the face of

climate change and increasing land pressure, which go hand in hand with energy

efficiency. In order to tackle the problems related to deforestation, land degradation

and loss of soil fertility, key factors, such as the use of cookstoves, must be identified

and adapted. The use of gasifier cookstoves can for example produce biochar, which

when used as a soil amendment, can sequester carbon, improve soil biology and

increase agricultural productivity.

Fieldwork results show that current cooking practices in the Gasabo and Kamonyi

districts do not enable efficient use of fuel. More than half of the farms that were

interviewed bought their firewood supplies, although functioning agroforestry

systems were observed on most of the farms. Food and crop waste was managed

through composts and mulching to cycle nutrients, and all farms fertilized their crops

with cow dung. Nonetheless, ever-increasing use of heavier fertilization was regarded

as a requirement to achieve anticipated crop yields.

Furthermore, optimized cookstove technology, such as the TLUD, the Philips Stove,

Biogas and Solar stoves are examined to discuss their economical suitability for rural

Rwandan households based on the criteria; fuel efficiency, time efficiency, household

air pollution levels and added benefits such as production of biochar in the case of

gasifier stoves or fertilizer from the biogas digester.
