I. Introduction
The Republic of Mali, or Mali for short, is a landlocked country in the Sahelian belt of West Africa. It
covers an area of 1.2 million km2 with a population of 16.3 million. Mali is one of the poorest countries
in the world, ranking 160 out of 169. The country currently faces an extreme food security challenge.
Three out of four households in the northern regions of the country are either moderately to severely
food insecure, or heavily dependent on food aid. These food issues are largely due to droughts over the
past two years. Over 95% of the region’s crops rely on rain irrigation and the droughts have led to
massive crop failures and increases in food prices, to the point where families cannot afford to eat.
Although lacking food and water, the one resource the region does not lack is solar radiation. The
country receives close to double the global average of solar energy. The enterprise proposed in this
report, Solar for Life, aims to capture the high solar potential of Northern Mali and apply it to irrigation
practices in order to solve the country’s dire food challenge. The enterprise will use a newly developed
system called a Solar Powered Drip Irrigation (SPDI) system, which combines two common technologies,
solar photovoltaic water pumps and drip irrigation, to decrease the dependency of crops on irregular
rain fall and give farmers the ability to grow high yield, high value crops throughout the year.
The project is based on a successful pilot run by Stanford University’s Program on Food Security and the
Environment in the country Benin located in West Africa, just south of Mali. Using some data from the
pilot as well as external research, financial projections show Solar for Life is able to yield a 23% internal
rate of return and offer a payback period of 3 years. The positive social impact include improved food
security, nutrition, income security and access to energy and water in certain periods of the year.
II. Country and Regional Overview
Mali is a landlocked country in West Africa where 51% is desert lands and 4% are arable lands under
natural conditions. Mali is the 9th poorest country in the world and ranks 182 out of 187 on the 2013
UNDP Human Development Indexi. The GDP per capita of Mali is $693.98 USD. The country is in a trade
deficit of over $2 Billion dollars, with the main export being gold and imports ranging from fuels, cement
and food staples (See Appendix A. In March 2012, President Amadou Toumani Toure was overthrown in
a military coup and civil unrest broke out between the interim government and four rebel groupsii. Some
experts have argued that food shortages and drought, acted as a tipping point to the civil unrest. The
opposing groups entered into a ceasefire in October 2013 and have been working on an agreement
which is anticipated to stop the fighting. The fighting has put additional strain on resources, like food
and water, and has disrupt some essential services. As such, political security is a concern for all
enterprises operating in the area.
III. Challenges: Food, Water, Energy
Food: The most pressing challenge for the people of Northern Mali is having enough food to eat and
water to drinkiii. The first concern among the local communities is to find a way to overcome the
endemic lack of water and agricultural produce that place the people of the region in a cycle of poverty
and poor health. In the northern regions around 50 percent of people have already sold off or
mortgaged their assets, further threatening
food security. 1.3 million continue to be in need
of food assistance throughout 2013 and into
2014. This number will rise to approximately 1.5
million people once those displaced by the
fighting return to their Maliiv. Although most citizens are engaged in agricultural production as their
main livelihood, they nevertheless spend 50–80% of their income on food, and are often net buyers of
food, particularly staples. Their high imports and food security issues are due to the region’s inability to
grow vegetables and staples because of the low and inconsistent rainfall.v Currently only 4 percent of
cropland in Mali is irrigated.vi Many grow low-value cereal crops that depend on a short rainy season, a
Figure 1 Oxfam – Food Security Map of Mali, April 23, 2013
practice that traps farmers in poverty and malnutrition. Reliable access to irrigation water could change
the farmers' situation. The development community is currently calling for investments in small-scale
irrigation projects and hydrologic mapping to help buffer the growers from the erratic weather and poor
crop yields that are expected to worsen in the future due to climate change and population growth.vii
Drinking Water: A lack of clean drinking water and poor sanitation systems has made humanitarian
organizations fear a cholera outbreak. Cholera is endemic in Mali, and last year 1,000 cases were
reported in the northern region. With a faltering water system in Gao and a lack of public health
facilities, providing safe drinking water is a critical challenge and need. viii
Energy: Electrification rates are very low in Mali, with 15% of rural towns and villages and 55% of urban
centers having electricity. The country imports all of its liquids fuels which includes diesel and gasoline.
Spending on fuels currently amount to up to 75-80% of the country’s operational expenditures which
makes the economy susceptible to swings in world oil prices. The shortage of energy coupled with
projected population growth creates an opportunity for developing the nation’s high solar exposure and
to support solar energy enterprises. The National Energy Policy governs Mali’s energy sector. There are
active efforts to increase renewable energy production in the country, with a goal of reaching 15% of
total energy production through renewables in 2020ix
IV. SWOT Analysis for Solar for Life
(SWOT diagram located in Appendix A) Strengths: One major strength of Mali is its geography. Average
solar radiation in Mali is well distributed over the nation with an estimated 5-7 kWh/m3/day and a daily
sun lighting duration of 7-10 hours; this is well above the global average of 4-5 kWh/m3/day. The
business environment is also friendly for solar development. There are active efforts by the government
in the National Energy Policy to increase renewable energy as a means for development and strengthen
energy independence.
Weaknesses: A weakness of using solar drip irrigation technology is that it is a fairly new technology and
therefore has a higher chance of mechanical failures. The technology will also be imported to Mali and
so shipment logistics and tariffs will need to be addressed. Training of local staff and ongoing
maintenance of the system will also need be considered. Finally, securing food contracts with buyers will
be an issue.
Opportunities: Mali is in dire need of food as well as being water scarce. Energy access is also a
challenge for the country. As the effects of climate change lead to longer droughts and as the population
continues to grow, these resource scarcity issues will only worsen. These challenges mean many
opportunities to improve food security through agricultural practices, like irrigation techniques, and for
enterprises which increase access to drinking water and energy.
Threats: The most significant threat is the current civil unrest that has affected the country for the past
two years and will increase the political risk of working in the country. Although the two fighting sides
are in peace talks, there is a chance that the negotiations won’t be successful or there is a relapse in
civility and fighting continues. Additionally, the nation’s food supply is currently highly dependent on
food and development aid and if the world’s economy worsen, withdrawal of foreign aid may affect any
enterprise that relies on their support.
V. Enterprise Proposal – Solar for Life
With Mali’s close proximity to the desert and high solar radiation, solar energy could be captured to
solve the country’s food needs. The proposed enterprise, Solar for Life, has the objective of utilizing
solar energy to improve food access to the northern regions of Mali through drip irrigation practices. It
also hopes to provide access to drinking water and energy as secondary objectives. In order to meet
these objectives, the enterprise consists of five components: solar drip irrigation technology, contracts
with food buyers, allocation of farm yields, solar charging services, and water access services. The
following section will go through each component of the enterprise through the Policy, Technology,
Enterprise framework. An additional analysis through the spider framework is in Appendix E.
Policy: Although agriculture is a mainstay in Mali, the sector itself is not heavily regulated. The
government encourages foreign investment in agriculture and charges a tax of 20% on producers.
Technology: The technology utilized is called a Solar Powered Drip Irrigation (SPDI) system which was
successfully piloted by Stanford University’s Program on Food Security and the Environment in northern
Benin. More information about the study can be found in Appendix B.
The SPDI system is a combination of two well used technologies, solar-powered water pumps and drip
irrigation tubes, however the marriage of the two technologies is fairly new. Drip irrigation is the most
rapidly growing type of irrigation in sub-Saharan Africa. The technology delivers water and fertilizer
directly to the roots of plants through low-lying tubes, thereby improving soil moisture conditions and
decreasing rates of evaporation. Cases of drip irrigation have resulted in yield gains of up to 100%, water
savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional
irrigation systemsx. The consistent rainfall and water efficiency allows for introduction of new
(potentially high-value) crops in regions where they could not be sustained by rainfall alone.
Solar-powered photovoltaic pumps save hours of labor in off-grid areas where water hauling is
traditionally done by hand by women and young girls. Diesel powered pumps are one option but since
Mali imports all of its liquid fuels, utilizing solar over diesel powered generators will make the farm
immune to fuel price fluctuations or shortages. In the medium- to long- term, solar pumps cost less than
traditional diesel-powered generators as well.
Solar-powered pumps and drip irrigation systems make an ideal pairing. Drip irrigation applications in
the developing world have been limited by reliable access to water. This can be solved by using solar
water pumps which enable the farmer to pump water from a nearby stream to the irrigated land.
Furthermore, the amount of solar radiation received is linked to pump speed, and since solar radiation is
the main driver of evapotranspiration, the pump speed will correlate to how much water crops need. xi
For example, the pump works faster when it is sunny and the plants need more water, and vice-versa. A
SPDI system is shown in Figure 2, where a PV array
powers a pump, which feeds water to a reservoir. The
reservoir then gravity-distributes the water to a low-
pressure drip irrigation system. Sizing of pumps,
reservoirs, and fields is done based on water
availability and estimated evapotranspiration needs for the region. When used together, solar water
pumps and drip irrigation allow farmers to grow during the dry season and produce profitable, high-
nutrition crops like fruits and vegetables in addition to the cereal crops they already grow. The system
will provide a much-needed source of both income and nutrition for the poor. (See Appendix C & D for
more details on the technology and requirements).
Water Access: Water can be accessed through the use of bore holes or from nearby streams. For the
first pilot, a nearby stream will be the water source as drilling boreholes will incur additional costs.
Farms can draw water from a small year-round stream using a floating motor pump.xii Ideal farm
locations for the pilot are in the purple box region on the water map of Mai in Appendix E.
Enterprise - Food Contracts: To ensure that there is a ready buyer for the produce harvested, and at a
predictable price, Solar for Life will enter into food purchase contracts with food aid organizations. This
is similar to power purchase agreement, only applied to food instead of energy. Food aid organizations,
like the United Nation’s World Food Program have been operating in Mali and providing emergency
food aid for over five years. With increasingly severe droughts and civil unrest, more food aid is now
being delivered than ever before. Much of the food donated is sourced from across the world and
shipped to Mali for relief, and so by purchasing from Mali farmers to provide to the country and
Figure 2 Technical drawing of a solar powered drip irrigation system
neighboring nations, aid organizations are able to cut down transport costs while at the same time
spurring the local economies. There is the risk that food organizations will not enter into contacts in
which case local governments or international buyers will purchase this food at a contracted price. The
ideal terms of the contract will be five years to grow high nutrients vegetables such as tomato, okra,
pepper, hot pepper, eggplant, carrot, amaranth, moringa, and other greens. The price will be at the
average food price (approximately $0.90/kg).
Enterprise - Yield Allocation: The farms will act as farming cooperatives where every farmer on the field
will have a stake on the crop’s profits and yields. The objective of the farm is not only to be financially
sustainable but to also increase the nutrition and food available to the community. Therefore the crop’s
yields will be allocated to meet this objective. 50% of the yield will be sold to the contractor(s) at global
food prices, 30% to be sold to market at a cost that is affordable within the town (assumed to be half
the cost of the world food price), and the remaining 20% stays within the co-operative and given to the
families for free. The allocation and targeted pricing will encourage farmers to manage the farm while at
the same time allowing enough to be exported to guarantee the financial payback of the project.
Enterprise - Solar Charging and Water Access: Drip irrigation requires watering approximately every six
days for about 75 minutes at a timexiii. This means that the utilization of the solar PV to pump water and
irrigate the land is approximately 3% of the year. xiv With the remaining idle time, the solar PVs can be
used to charge cell phones and solar lamps through a pay-per-use system. Additionally, some of the
energy can be used to pump water for drinking purposes. The drinking water will need to be filtered and
stored in a second container but can then sold by the liter at a low cost to the local community market.
VI. Economics, Operations and Financing
Economic feasibility: Financial projections show that Solar for Life is economically sustainable. The 5-
year financial analysis located in Appendix G shows an enterprise payback period of approximately 3
years, 23% internal rate of return and a positive NPV. These returns are based on the ideal scenario
where food aid or government buyers agrees to purchase 50% of the crop yields at the average world
food price of $0.90/kg, 30% of the yield is sold at a discount in the local market at $0.45/kg and 20% of
the yield is given for free to the farmers. A pessimistic scenario (Appendix H) where no food contract is
obtained and all food is sold on the local market at $0.70/kg (still below world food prices) would yield a
payback period of 3.5 years and a 17% internal rate of return. Both scenarios assume average monthly
farm yields would produce 2,000 kg of produce. All assumptions and their sources used to derive these
financial projects can be found in Appendix G & H.
Revenue: Revenue is projected at $15,000 USD per year, with gross margins at $9,000 USD per year.
Revenue is derived from four areas: food contracts fulfillment, local market sale, solar charging station,
and water sales. The organization’s objective is to address the food security challenges of Northern Mali
and provide access to water and energy, while at the same remaining financially viable. To reach these
objectives, the pricing for each product/buyer is adjusted accordingly. 50% of the yield will be sold
through contracts at the global food price, however to compensate the buyer for bearing the risk of a
long term contract, the contract price per kg will be on the lower end of the world food price spectrum.
In order to ensure local consumers can afford the food, a 50% discount on the world food price will be
applied to 30% of the yield and sold at the local market. The remaining 20% of the yield will be given
free to the farmers to either consume or sell themselves for additional personal revenue. Revenue will
also be obtained through solar charging using the PVs when not in use for irrigation. Customers will
charged on a per kilowatt basis. Lastly, revenue will be charged on a per liter basis of the water that is
filtered and sold by the liter. (See Appendix I for revenue model diagram)
Capital and operating costs: Total capital costs amounted to $8,500. The capital costs for the Solar PV &
drip irrigation system include the equipment, installation, and training. In terms of the solar charging
and water services, capital costs include the upgrades needed to run the solar charging service as well as
the water filtration equipment and installation. Operating costs are based on the Stanford Benin project
and include inputs such as fertilizer, labor, and support technicians. Further costs relating to operating
the solar and water services were added. Total operating costs amounted to 6,000. See Appendix G for
all the costs and assumptions.
Financing: Capital will be raised mostly through development banks, such as the Asian Development
Bank, World Bank, and African Development Bank. Since food contracts will be obtained, the cost of
financing should be lower, or at least, will increase the likeliness of Solar for Life to obtain financing. To
support the local economy, a portion of the financing will also come from micro-finance in the area.
Alternative sources of financing could be obtained from impact investors, commercial banks or grants. A
5-year payback and conservative borrowing rate of 8% was used, although it is likely that the enterprise
would be able to negotiate a cheaper rate and more favorable terms if food contracts are secured.
Training and Maintenance: Training will be required for operating the solar drip irrigation system,
cultivating the new crops, running the solar charging station, and operating the water filtration system.
The initial training will be provided by an agriculture expert, solar PV expert, and water expert. Local
personnel with experience in agriculture, water management, and electricity will be recruited to work
on the farm for a one year contract to train and address any technical errors in the first year of
operations. An organizational chart is provided in Appendix J.
Implementation: The project will roll out in 5 phases. Each phase is described in Appendix K.
Measuring Impact: It is important to consistently evaluate the pilot’s effectiveness to decide whether to
replicate the concept in other parts of Mali. One framework is the planet, people, profit. Additionally,
metrics from IRIS can also be used. A list of suggested metrics can be found in Appendix L.
VII. Risks and mitigations
There are three key risks to Solar for Life which may impact the implementation. The first relates to
securing buyers through the food contract price agreements. If Solar for Life is not able to obtain buyers,
one alternative is to sell to a local market at slightly below the international food market cost at
$0.70/kg which would still yield a 17% internal rate of return. This alternative scenario can be found in
Appendix H. A second key risk is crop failure or technical breakdowns. To mitigate this risk, the first year
of the pilot would see two experts (one in agriculture and one in solar engineer) contracted to the
project to monitor its progress and immediately address any technical issues. After the first year, these
experts will have trained local staff to handle any issues that may arise. The last risk is that civil unrest
continues and threatens the safety of the farmers. Currently both fighting groups are in negotiations as
it comes closer to implement the project, political risk will need to be re-assessed. To prevent legal
repercussions of not fulfilling the food contracts due to civil unrest, a clause in the contract will be
written stating a renouncement of the contract if political risk deems the project unsafe to continue.
VIII. Recommendations
Food security is the most significant and pressing issue the country of Mali currently faces. The decline
in agricultural production is attributed to droughts and so by utilizing the country’s abundant solar
resources, Solar for Life can use solar powered drip irrigation technology to solve the nation’s food
needs. In order for Solar for Life to move forward, it must first obtain contracted food buyers. Next is to
identify farms and location for pilot and obtain quote for all equipment. Third is to obtain financing
through development banks and other funding avenues. Fourth is to assemble the team and purchase
equipment. Finally, the enterprise will set up and begin operations, with continual monitoring of results.

Appendix B: Stanford Study
Key Points from the Study:
I. Jennifer Burney at Stanford University’s Program on Food Security and the Environment (FSE)
conducted a study in villages in northern Benin using Solar Drip Irrigation technology. Household
survey and field-level data in the first year showed that solar-powered drip irrigation
significantly augmented both household income and nutritional intake, particularly during the
dry season, and is cost effective compared to alternative technologies.xv
II. FSE published its findings in the Proceedings of the National Academy of Sciences in January
2010. Researchers found that income and nutrition have improved significantly for women and
their families since the project installed three solar irrigation systems in 2007. The study also
concluded that the project is cost-effective and environmentally sustainable. The systems
should pay for themselves in approximately 2.3 years; and they are durable, emissions-free, and
more economical over time compared with gasoline- or diesel-powered water pumps.
III. For the first time, women farmers in the rural villages of Bessassi and Dunkassa in northern
Benin were able to grow vegetables and fruits during the six month dry season, improving food
security and nutrition for themselves and their families. Farmers are also increasing their income
by selling excess crops in the market. Now entering its third year, the project has proved that
solar energy can provide long term solutions to hunger, malnutrition and poverty in developing
nations.xvi
IV. The farms enough returns for women to send kids to school or buy small business equipment
like a sewing machine or market stall. Burney believe the technology has become a ladder out of
poverty.
Demonstrated Impacts of the Benin Project:
Improved food security: altered local vegetable availability
Improved nutrition: In villages irrigated with solar-powered systems, vegetable intake
increased to three to five servings per day;
Improved income security: women earned an extra $7.50 per week from the sale of fresh
produce at the local market;
Empower Women: Reduced time spent collecting water for women;
Preserve the Environment: Prevention of greenhouse gas emissions from reduction in
inefficient agricultural practices;
Increase access to energy: Increased market opportunities for solar energy.

maintenance
iii. Current solar pumps – expensive, at about $7,000
iv. SunWater pumps cuts cost about 80% to about $1,000 by concentrating solar radiation using
mirrors onto PVs to increase efficiency and power output. Also uses less expensive irrigation
