Abstract
Climate change is a global issue that is not evenly distributed in causes and effects. While the industrialized
nations are the major causes of climate change, the effects of climate change hardest hit the developing nations.
The whole of sub Saharan Africa account for less than 2 percent of global greenhouse gas (GHG) emissions. The
developed countries with greater historical responsibility for climate change and a greater capacity to act should
take the lead in dealing with climate change. On the other hand, the emerging economies and developing
economies should have mitigation measures in place for their own emissions. The domestic energy sector is the
largest energy-consuming sector in Nigeria and Uganda with the effects of climate change quite visibly seen in
both countries. This paper compares the climate change impacts, policies, governance structures and method of
approach to climate change in both countries and puts forth recommendations on how to mitigate and adapt to
climate change in the domestic energy sector.
Keywords: Climate change, energy, sustainability, GHG emissions
1. Introduction
Sustainable development refers to the pattern of resource use that meets human needs while preserving
the environment so that generations yet unborn can also meet their needs in the future (Sambo 2009). Sustainable
energy is essential for sustainable development. Access to affordable, reliable energy advances education,
empowers women, and creates economic opportunities. Climate change is a long term threat that is currently
affecting every part of the globe. With the resultant disruption of economic activities, climate change is no longer
just an environmental issue but also a developmental issue in developing countries. It affects all sectors from
energy, agriculture, health and sanitation to forestry, biodiversity, coastal water and fresh water resources and so
on. Recent estimates suggest that in the absence of mitigation and adaptation measures, climate change could
result in a loss of between 2 percent to 11 percent of Nigeria’s GDP by 2020 and rising to between 6 percent and
30 percent in 2050 (NASPA-CCN 2011). The United Nations Framework Convention on Climate Change
(UNFCCC) has the main objective of mitigating climate change through the Kyoto Protocol and the purpose of
the Clean Development Mechanism is to assist developing countries (Non Annex 1) that are parties to the
protocol achieve sustainable development as well as the developed nations (Annex1) comply with their certified
quantified emission limitations. Nearly 3 billion people around the world rely on wood, coal, charcoal or animal
waste for cooking and heating (United Nations report 2013). Nigeria is richly endowed with conventional energy
resources (oil, gas, coal, bitumen and lignite) as well as renewable energy resources such as hydro, wind and
solar. Aside hydro, the natural resources are largely untapped. It is the largest oil producer in Africa and has the
second largest proven crude oil reserve in Africa exporting most of its crude oil to Europe and the United States.
Nigeria is a member of the organization of petroleum exporting countries (OPEC) and relies heavily on the
petroleum sector for its economic growth. The sector contributes 76 per cent of the government revenues
(Economic Report on Africa, 2013). She has a proven crude oil reserve of 37.14 billion barrels and a daily
production of about 2.5 million barrels per day with plans by the government to hit the 40 million barrels mark in
reserve by the end of the first decade of the millennium with a daily production of 4 million barrels by the target
date. With a proven natural gas reserve of 260 trillion cubic feet, Nigeria gas reserve is triple the crude oil
resources and it’s rated the world’s number 1 in gas flaring because most of the associated gas during the oil
production is being flared. Plans are under way to end gas flaring and develop the domestic gas market. Flaring
intensity has reduced by 60 per cent between 2003-2012.The domestic sector is the largest energy consuming
sector of the economy and accounts for about a quarter of total commercial energy and over 90 per cent of
traditional fuels especially fuel wood in the country (Adegbulugbe & Akinbami 1992). Predominant energy
sources in this sector are fuelwood, charcoal, kerosene, liquefied petroleum gas (LPG) and electricity. The rural
households which constitute 49 percent of the population (according to the world bank data in 2013) depend on
unsustainable fuel wood use for their domestic activities. Abundant energy resources including renewables also
characterize Uganda having discovered oil in 2006. Proven crude oil reserve in 2014 is 2.5 billion barrels and
commercial oil production is expected to start in 2018. The domestic energy sector in Uganda is predominantly
dependent on wood fuel and biomass which accounts for up to 93 per cent of the country’s total energy
needs .The main other sources of energy are petroleum products (6 per cent) and hydro-electricity (1 per cent)
(Knofle 2004). The high dependency on wood fuel and charcoal has implications on carbon production through
25

deforestation and carbon dioxide emission through combustion. Developing nations are thus both a contributor to
climate change processes and vulnerable to the effects of carbon dioxide accumulation in the atmosphere. Wood
fuel is the main source of heating and cooking in rural and urban areas (Uganda Bureau of Statistics 2009). The
household sector will remain in the medium term, a developing country’s most relevant energy sector in terms of
access, energy efficiency, environmental impact, rural livelihoods and lost government revenues. Total household
demand for firewood and wood for charcoal is 22.2 million tonnes per year with cottage industries adding a
further 5.5 million tonnes of demand for a total of about 27.7 million tonnes for the entire country (Uganda
National Report 2010). This leads to a lot of wastage due to the inefficient cooking technologies employed. An
estimated 90 per cent of Ugandans live in rural areas with less than 3% electricity access (daily monitor 2013).
Both countries are greatly vulnerable to climate change impacts, in respect of climate variability including
increasing temperatures, increased frequency and intensity of rainfall, heat waves, droughts, floods and storms.
Climate change is being experienced in various forms such as rising temperatures, changing rainfall patterns,
increased frequency and intensity of droughts and floods, decline in quantity and quality of water resources,
reduced agricultural productivity, spread of vector borne diseases and heavier storms (UNDP 2012). Nigeria's
key vulnerabilities to climate change, as stated by Nigeria's First National Communication (FNC) on climate
change are Exposure of northern Nigeria to accelerated desertification linked to increasing drought with resulting
impacts on the local population and the natural resource base and sensitivity of other sectors of the economy to
climate variability such as Nigeria's electrical supply, which is heavily dependent on hydropower and thus is
affected by fluctuations in rainfall amongst others. There is evidence that average temperatures have increased
by as much as 1.4 degrees Celsius since the 1960s, looking further ahead, up to 4.3 degrees Celsius change in
average temperatures by the 2080s is possible in Uganda (Corner 2011). Based on Intergovernmental Panel on
Climate Change (IPCC) report for Nigeria, a possible sea level rise from 1990 levels to 0.3m by 2020 and 1m by
2050 with a rise of temperature up to 3.2 degrees Celsius by 2050 is predicted. A temperature rise of that
magnitude would have disastrous consequences for both countries.
Nigeria and Uganda have a generally low GHG emissions profile. A GHG emission per capita of 2.25tCO2e and
2.05tCO2e respectively (this is less than 10 percent of GHG emission per capita in the United States) however
emissions are steadily increasing due to economic and population growth as a result of demand for energy,
industrialization and private transport. However, the greatest source of GHG emissions is from land use change
through the continued depletion of forest cover and agricultural activities. Climate change-related disasters
contribute well over 70 per cent of the natural disasters and destroy annually an average of 800,000 ha of crops,
resulting in economic losses of over UGX 120 billion. The annual economic losses resulting from the associated
transport damage, accidents, fires are estimated at UGX 50 billion (UNDP/UNEP 2009).
2. Climate change and Energy security
2.1 Impact on Electricity Demand and supply to Households
Both countries have one of the lowest electricity generation and consumption rates in the world. Nigeria’s per
capita electricity consumption is 4 times less than the African average and about 19 times less than the world
average (Sambo 2009). Per capita electricity consumption currently stands at 107kWh for Nigeria. Total
electricity generation from hydro and thermal power plants is less than 4,000MW for a population of about 160
million. Per capita electricity consumption in Uganda is 22kWh. Hydropower contributes about 32 per cent of
net electricity generation and there exist hydro potential in excess of 11,000MW in Nigeria (Zarma 2006). The
present and ever increasing population with the total capacity of the available power stations reveals that Nigeria
is not able to meet the energy needs of the people. The rural dwellers still lack electric power (Oyedepo 2012).
Model for analysis of energy demand (MAED) was used to model the demand structure of Nigerian energy
sector in four scenarios (reference growth, optimistic growth, high growth I and high growth II). With the
reference growth scenario (GDP grows at 7 percent per annum), electricity demand in 2020 is 50,820MW as
shown in Table 1 (Energy Commission of Nigeria 2006). Electricity supply from hydro in 2020 is 6,619MW as
shown in Table 2. This reveals a wide gap between electricity demand and supply from hydro at present and in
the future. There would still be a shortfall in energy supply even when all hydro potentials in Nigeria (large and
small) have been developed. There is therefore the need to explore other natural resources such as solar. In
Uganda, hydro power contributes over 90 percent to net electricity generation (African Union Report 2008).
According to IPCC, water resources are more susceptible to global warming. Effects of climate change on water
resources manifests as periodic droughts and floods that reduces hydro power generation capacity. A predicted
rise of temperature of 3.2 degrees Celsius by 2050 will increase peak energy demand above the baseline
scenarios. About 5 million households (85 percent) of the population lack access to electricity, most Ugandan
homes use kerosene lanterns and candles in their homes. Currently, domestic power demand exceeds the
available supply by as much as 80 MW during peak periods, and is growing at the rate of 8 per cent per year in
Uganda (UNDP/UNEP Report 2009). Load shedding is a common similarity and the shortfall in generation
26

Vol.4, No.8, 2014
capacity is limiting growth in many sectors of the economies. The Council for Renewable Energy of Nigeria
estimates that power outages brought about a loss of 126 billion naira (US$ 984.38 million) annually. Although
11 percent of the population in Uganda can access the grid, electricity is mainly for the purpose of lighting. Lake
Victoria which is the second largest freshwater lake in the world is the source of power generated by Owen falls
dam and Kira dam with a combined generating capacity of 380MW. Low water level in Lake Victoria has caused
reduction in electricity generation by over 60 per cent. This has led to increase in electricity tariffs due to
additional power generation from thermal sources. The cost of hydroelectricity to every consumer is subsidized
by 35 percent of the tariff. This makes it even more difficult for households to afford as taxes on petroleum
products are as high as 35- 40 percent.

2.2 Impact on Fuel wood Demand and Supply to households
In many African communities, women bear the brunt of domestic activities. Charcoal is the predominant source
of energy used in urban settings, while firewood is more common in rural areas of Uganda. LPG supply and use
in Uganda is very minimal and limited to middle-class town residents, mostly in Kampala (see Tables 3 & 4).
When it comes to shortage of fuel wood, women are more helpless because of their responsibility for firewood
collection and cooking, and are exposed to diseases associated with smoke during cooking. To address the
problem of wood scarcity, women often resort to negative coping mechanisms such as undercooking their meals
especially meals that reportedly take a longer time to cook, reducing the number of meals per day, and even
selling part of their food ration to buy firewood (Bizzarri 2009). The number of people who live with inadequate
calorie consumption – 14 million Ugandans in 2002 – has increased in 2008 to 68 percent of the total population
(27 million), due to increased incidence of climate change disasters that continue to disrupt food production and
incomes (UNDP, UNEP 2009). The inability to create wealth from Nigeria's flared gas or to develop alternative
ways of using it to meet energy needs of households in both rural and urban areas is partly responsible for the
increasing fuelwood demand. Nigeria is ranked among the countries with lowest per capita LPG consumption of
0.5kg. The Federal Government spends 222 billion naira monthly on the use of firewood and kerosene for
cooking. This economic loss will continue until the government show significant commitment to the use of LPG.

2.3 Impact on the Economies
Climate change can affect many important sectors of the economy by influencing the supply of and demand for
goods and services. Empirical evidence shows that there will be changes in the supply and demand of food
commodities as a result of low yields resulting mainly from drought and flooding events. The changes will also
affect the profitability of farming and the affordability of food (Chika & Ozor 2010). Climate change and the
threat of related extreme conditions have major implications for development particularly in developing
countries. Unlike Nigeria with the largest economy in Africa, the economy and the well being of the people of
Uganda are tightly bound to climate, especially because over 80 per cent of the population is rural and depending
on rain fed agriculture, that is prone to impacts of climate variability. Uganda is the largest coffee producer in
Africa and it is Uganda’s largest foreign exchange earner and Tourism is the third largest foreign exchange earner.
Small variations in weather conditions (temperature and rainfall) affect coffee flavor and hence the value of the
product. Coffee production and prices have declined in recent years. A kilogram of Uganda coffee sold at
approximately $4 in 2011 dropped to $1.30 in 2013 (UNDP 2014). This hurts the wider Ugandan economy since
the industry employs more than 2 million people directly or indirectly and contributing $400 million to the
Uganda economy in 2012. Without adaptation strategies, future production losses induced by climate change are
estimated to reach tens of millions of dollars annually (Jassogne 2013). Tourism has remained one of the fastest
growing sectors of the economy contributing over US$834 million to GDP in 2012, this represented 4% of total
Ugandan GDP (www.redpepper.co.ug). The sector alone employs country-wide an estimated 65,000 people with
the related transport sector accounting for another 20,000 jobs. Food prices, Tourism and coffee production are
the most sensitive and could affect the economy largely while hitting hard on the domestic sector.
3. The Forest Situation
Forests and forest products can play a significant role in mitigation of harmful effects of greenhouse gas
emissions. They can act as a “sink” to absorb emissions and store large quantities of carbon for extended periods
of time. Forests are also an important component of adaptation strategies needed to address continuing changes
in the natural resource base that sustains our livelihoods (Gbadegesin & Olorunfemi 2011). Historically over 35
per cent of Uganda was covered in forest, however rapidly increasing levels of deforestation have cleared over
50 per cent of forests to an extent that at present forests account for less than 15 per cent of Uganda’s land cover.
The trend in Uganda is one of loss of forest cover and degradation of the remaining forest resource base. A major
factor that causes deforestation in Uganda is the need for fuel and timber. With a population of about 35 million,
Uganda has over 90 percent of its total energy demand from biomass and trees are still expected to contribute up
to 75 percent by 2015 (UNDP/UNEP 2009). The lack of modern and affordable fuels for domestic use has forced
both the rural and urban population to rely on charcoal and firewood as their source of heat energy. This has led
to massive deforestation due to pressure exerted on the natural forest. Uganda’s forest cover is 24 per cent of the
land cover and is likely to decrease with increasing population dependent on it. In the Global forest Assessment
Report, the Food and Agricultural Organisation (FAO) said the forest cover has reduced from 4,924 million
hectares in 1990 to 3,627 million hectares in 2005. Woodlands provide the bulk of firewood and charcoal used in
the urban areas. Degradation is more marked in the woodlands as most of the current loss of forest cover occurs
in the woodlands (see Table 5). In high tropical forest, about 280,000 hectares is now degraded representing at
least a third of the country’s valuable high forest (Uganda Forestry Policy 2001). At global level, about 40
percent of all the carbon emitted by human activity has come from cutting forests and increased industrialization.
Stopping deforestation is, in principle, cheap and simple (Arthur & Namuteefa 2013). Nigeria is blessed with a
large expanse of land and variable vegetation, but this important resource is not sustainably used or managed.
The deforestation rate is about 3.5 per cent per year translating to 300,000 – 400,000 ha of forest land per year.
Presently, forests occupy only 10 percent of Nigeria’s forest land area (Ladipo 2010). Recent studies suggests
that present-day forest cover is under pressure as a result of human activities such as agricultural development
where vast lands are cleared without conservation considerations, large-scale peri-urban housing project
development, fuelwood generation, uncontrolled forest harvesting including poaching for logs and poles, and
urbanization (Ladipo 2010). Fuelwood exploitation in both the forest and savanna regions is unsustainable as
most fuelwood collectors do not plant trees to replace those removed from the vegetation for fuelwood
(Gbadegesin & Olorunfemi 2011).

4. Challenges in Mitigating Climate Change
Energy policy institutional arrangement is a challenge being faced by developing nations. The government of
Nigeria has many broad environmental policies that may not provide a strategic focus in mitigation and
adaptation to climate change though the environmental laws which promote sustainable environmental
management can influence on the adaptation and mitigation measures on climate change. The Climate Change
Unit (CCU) is reliant on global scale models as the analysis tool which only allows for a generalized assessment.
There is need for tools for climate change analysis, impact assessment at national and regional levels. Other
challenges are:
• Lack of awareness on climate change issues
• Inadequate financial incentives to stimulate the spread of clean energy technologies
• Lack of up to date data on the environment such as the extent of deforestation and volume of renewable
and non-renewable biomass. Database on fuelwood and other biomass energy consumption are usually not
reliable and in many years not readily available.
• An adequate legislative framework to support and enforce the implementation of energy efficiency and
29
conservation.
• Inadequate data on the current status of forestry resources in general and woody biomass situation in
particular.
5. Mitigation and Adaptation Options and the way forward
Both Nigeria and Uganda are parties to the Kyoto protocol which was adopted in December 1997. Both
countries do not have an existing climate change policy in place. The need for Nigeria to adopt a more
comprehensive and coordinated approach to the issues of climate change within its national development context
than what currently obtains is pertinent. Significant national efforts are needed to ensure that climate change
concerns are properly integrated into the country’s Vision 20:2020, which currently constitutes the country’s
blueprint for sustainable rapid socio-economic development. In developing a national response to climate change,
the governance structure should be fully in place and functional at the various levels of governance. More
importantly, Nigeria should develop its government priotized actions aimed at reducing or limiting GHG
emissions. This is expected to be the main vehicle for mitigation actions normally referred to as Nationally
Appropriate Mitigation Actions (NAMAs). However, the NAMA development in Uganda has made significant
achievements. The European commission and the governments of Germany and Austria provided funding and
the technical input needed was provided by the climate change unit and the United Nations Development
Programme (UNDP) under its Low Emissions Capacity Building (LECB) programme. Uganda has in place
active national and international organizations in the energy sector with various programs in energy efficiency
and fuel switch that will mitigate the effects of climate change. Also, the East African Community Climate
Change Policy (EACCCP) which came into existence in 2011 has the broad objective of creating a sustainable

Vol.4, No.8, 2014
environment in the East African Region through Mitigation, Adaptation and Climate Change research. Each
member state is guided and reinforced to draw up and implement its climate change policies. Uganda recognizes
Climate Change as a major risk factor to national development and specifically energy poverty eradication to
achieve sustainable development. This guided the preparation of its National Adaptation Plan of Action (NAPA)
and Nationally Appropriate Mitigation Actions (NAMAs). In developing mitigation and adaptation measures
that can be adequately implemented in the domestic sector, particular focus for both countries should be in the
following areas:
5.1 Improve rate of Energy Efficiency
Energy efficiency in domestic activities like cooking and lighting can be increased through the use of more
efficient cooking technologies like Improved Cook stoves (ICS), gas burners and Compact Florescent light bulbs
(CFL). These are also energy saving measures. Increased savings encourages investments and development.
Currently, Uganda has many ICS projects being executed by international organizations, donor agencies and so
on in the rural areas which holds about 85 percent of its total population, however most of the ICS project do not
have the carbon finance aspect embedded in it to enhance sustainability. Two ICS projects designed to
disseminate 100,000 and 40,000 ICS to households in northern Nigeria by 2015 is being implemented. The
projects have the carbon finance aspect embedded in it for sustainability. More of such projects should be spread
across the length and breadth of Nigeria. Of particular point and urgency to Nigeria is the utilization of the
associated gas being flared during oil production for domestic use. Although Nigeria has crude oil and gas
resources, the levels of gas and kerosene cookers and cooking stoves adoption are far below the levels that could
make any impact (Gbadegesin & Olorunfemi 2011). Results from recent study show that an annual average of
2040 MJ of fuelwood is consumed in Nigeria, 77.3 percent of the sourcing is done by children and the time spent
in fuelwood trips is between 4 and 5 hours, at a frequency of three to four times a week. This amount of
fuelwood consumed examined alongside 2.5billion standard cubic feet of gas flared per day, revealed the
quantity of energy that ought to be saved and related avoidable extreme weather conditions that prevail in
Nigeria (Nwanya 2011).
5.2 Identification of issues which require investigation and providing results through advocacy and research
Training and public awareness amongst households on climate change, adaptation and mitigation measures
should be encouraged. Technical assistance and financial support from international organizations and donors for
capacity building, resource management and risk reduction initiatives should be optimized. In addition, strategic
advice with structures in place to report progress should be explored. Particularly, the government of Nigeria
needs to fully re-organize and make functional the National Strategic Climate Change Trust Fund as a channel
for broadening the scope of national and international interventions on climate change.
5.3 Explore economic benefits of Carbon Finance
For sustainability of projects that improve energy efficiency and save energy in the domestic sector, carbon
finance is important. Carbon credits are an immediate answer to reducing the amount of GHG emissions in the
atmosphere. The generation and sale of carbon credits funds carbon projects which would not have gone ahead.
Carbon credits also help lower the costs of renewable and low carbon technologies as well as assisting in the
technology transfer to developing countries. There exist the compliance and voluntary carbon markets. In the
compliance market, carbon credits are generated by projects that operate under one of the UNFCCC approved
mechanisms such as the CDM. The voluntary carbon markets function outside of the compliance market. They
enable businesses, governments, NGOs, and individuals to offset their emissions by purchasing offsets that were
created either through the CDM or by the voluntary carbon standards. The latter are called VERs (Verified or
Voluntary Emissions Reductions). Compared to the compliance market, trading volumes in the voluntary market
are much smaller because demand is created only by voluntary buyers (corporations, institutions and individuals)
to buy offsets. The CERs and VERs when converted into cash or any other beneficial form (e.g. development
project in the community) encourages the households to get involved in climate change issues and be better
informed on the trends, developments and policies as it relates to climate change. It also encourages the use of
clean energy technologies such as solar lamps and cookers and energy saving light bulbs.
5.4 Production of Biogas from Animal Waste
Biogas (a mixture of methane and carbon dioxide produced from anaerobic decomposition of animal waste)
reduces GHG emissions by replacing the combustion of non renewable biomass thereby reducing carbon dioxide
emissions. It can also reduce methane emissions by diverting animal waste that would otherwise decompose in
open pits emitting methane. The slurry serves as fertilizer to boost food production. Biogas plants can also earn
certified emission reductions (CERs) or VERs provided the appropriate methodologies and monitoring and
evaluation procedures laid out by UNFCCC or any other voluntary standard(s) have been followed. The impact
30

Vol.4, No.8, 2014
of biogas plants on the domestic sector is to reduce the financial cost expended by households on cooking and
lighting and for environmental sustainability. The first phase of the biogas program in Uganda has 12,000 biogas
plants installed in rural households within a five year period while the second phase (2014-2017) will install a
further 13,100 biogas plants. The biogas project has a carbon finance component to ensure expansion and
sustainability. Nigeria is an agricultural nation with 70 per cent of its population involved in different
agricultural activities. It is the largest livestock producer in sub Saharan Africa (Ikhatua 2000). Statistical data
have been scarce on livestock population, however ruminant domestic population has been put at 13.9 million
cattle, 34.5 million goats and 22 million sheep (Ikhatua 2000). Biogas potential has been estimated at 6.8 million
m3 per day (Mshandete & Parawira 2009). Based on a design selection report, a 6m3 fixed dome bio digester is
the preferred size for most rural households. 3 - 4 non grazing cattle will produce 1.7m3 of biogas daily which
can sufficiently cook meals up to 4 hours on a single gas burner and can power a lamp for 4-5 hours. With the
livestock population, biogas can adequately provide the energy needs for domestic activities in rural households.
A lot of awareness and capacity development by government and NGOs is required for the adoption of this
technology by rural households in Nigeria.
5.4 Efficient and sustainable Charcoal production and Utilization
The need for fuel wood stems from low electrification rates in both countries. For many urban households,
charcoal provides a reliable, convenient and accessible energy source for cooking at a stable cost and majority of
households depend on charcoal for their daily energy needs. Continuous urbanization and population growth
translates into increasing demand for charcoal and the economic importance of the charcoal sector is substantial
(Martijn 2010). Charcoal consumption in Uganda was over 300,000 tonnes per year in the last decade. The ever
growing demand for charcoal contributes to sustainability challenges which must be addressed so as to
continually meet the energy demands. Reforming the charcoal sector is one of the most important opportunities
to not only reduce emissions but also achieve multiple sustainable development outcomes. Sustainable charcoal
production has the potential to attract carbon finance. The environmental challenges in the charcoal sector
predominantly lie in forest management, production and consumption of charcoal. Deforestation occurs as a
result of unsustainable harvesting (forest practices) and pollution of the environment is as a result inefficient
kilns during firing and inefficient cooking technologies employed. Economic and societal issues also arise in the
value chain such as evasion of licensing fees and taxes and improper value placed on charcoal. The power
players are mainly found in transportation and wholesaling dealing in large volumes of charcoal. By controlling
the middle of the supply chain, they are able to dictate many aspects of pricing in the value chain leading to
lopsided income levels from stage to stage of the entire value chain (Roop 2013). In a NAMA study in Uganda,
Basu et al (2013) proposed a twenty year progression in which the traditional earth kilns are replaced by the
Cassamance Kilns and ultimately by Adam retort kilns (there are no further changes in years 2026-2030). The
former kilns shows higher levels of efficiency and reduction of GHG emission comes from the reduced amount
of wood needed to be pyrolized to produce the needed charcoal and the latter kiln also improves efficiency and
greatly reduces GHG emissions (see Table 7).

5.4 Increase Stakeholder participation in Sustainable Afforestation Programs
Increase stakeholder participation in sustainable afforestation programs and emphasize its economic benefit from
carbon finance perspective. Capacity development programs on climate resilient agriculture should be put in
place in addition to necessary support for the implementation of the National forestry Policy whose main goal is
towards ensuring a sustainable forest management and adopting an integrated approach to forestry development.
Trees are a source of fuel wood and income as well as a sink for carbon dioxide released to the atmosphere.
6. Conclusion
Energy efficiency, renewable energy, afforestation/deforestation and finance are pertinent to curbing the effects
of climate change in the domestic sector and are focal points to which the government of both countries should

Vol.4, No.8, 2014
engage meaningfully to achieve economic growth and environmental sustainability. In addition, climate change
mitigation through the Clean Development Mechanism and Voluntary Carbon Markets will significantly benefit
the countries in the near future. Increasing hydro generation capacity and grid expansion to improve access to
electricity are opportunities for Low-carbon energy generation with economic benefits which should be explored.
Particularly, the government of Uganda should address the Lake Victoria declining net basin. Finally, a favorable
economic environment through public/private partnership is important.
