First Irrigation Engineering Graduates Enter the Market in Style
It What exciting time lies ahead of us? This is probably a question that preoccupied the First Irrigation Engineering Graduates
during their student life at the College. The Arusha Technical College, popularly known as ATC, was upgraded to autonomous institution in 2007 to replace the then Technical College Arusha that was founded in 1978. It started operating autonomously in July 2009 and immediately, in response to market demand and as a part of support to the realisation of the National Irrigation Master Plan (NIMP) the College introduced a Civil and Irrigation Engineering programme leading to the award of ordinary Diploma and Bachelor’s Degree respectively. The Master Plan is supported by the Tanzania Development Vision 2025 and the “KILIMo KWANZA” strategy. The Process of developing Curriculum for this programme was guided by NACTE provisions with effective involvement of stakeholders.
Key NACTE provisions applied were level descriptors and learning outcomes. The process requires determination of labour market demands through situation analysis as a first step towards curriculum development. As a second step the findings of the Labour Market Demands were synthesized with NACTE guidelines in a Situation Analysis Report. This Report was applied to develop Curriculum in a writers workshop comprising a strategic
mix of selected members from the Ministry of Agriculture and Food Security, Local Government, Contractors, Sokoine University of Agriculture, and Agriculture Research Institutes, among others.
The College also developed an implementation plan to guarantee that the training to be offered is of required quality, experiential in nature with entrepreneurship development component to motivate students to opt for self employment activities after completion of their study. The developed curriculum and its implementation plan were presented to a stakeholders workshop to confirm if it adequately addressed the needs of both irrigation engineering industry and professional bodies. This step in addition to approving the curriculum, also ensured that the graduates could be relevant to society. As a part of Quality Assurance framework of the College, practicing professionals, professional bodies and the views of other stakeholders were taken into consideration.
The College mobilised the required resources both human and facilities to impart the necessary knowledge, skills and good attributes engraved in the curricula as demanded by Irrigation Engineering Industry and allied stakeholders. Further, the College recruited a total of 5 qualified academic staff in the Civil Engineering Department, contracted visiting Lecturers/Professors from institutions such as Sokoine University of Agriculture, University of Dar es Salaam and Dar es Salaam Institute of Technology among other Institutions. Further, the College, requested for support of Irrigation Experts from the Government of Japan to build teaching capacity especially in design and practical classes. The Japanese Government dispatched two Experts from June 2010 todate to work with ATC is realizing this noble dream.
In order to support teaching, a Demonstration Farm was constructed within the ATC campus to demonstrate field irrigation techniques for gravity irrigation and pressurized irrigation
technologies. In addition, the College is in the process of establishing a 150 acres Irrigation Training Farm 15 km away at VETA oljoro area to support teaching practice. Currently, drilling of boreholes and construction of rainwater harvesting system are in progress. In addition, in each academic year Students attend Field Practical Training in Irrigation Schemes and Design Offices for ten weeks where they work under supervision of contractors, consultants, and Irrigation Officers.
The first batch of Students who pursued this three academic years Bachelor’s Degree Programme and successfully fulfilled the requirements for the awards, graduated with Bachelor’s Degree in Civil and Irrigation Engineering in January 2014. These are the first graduates in this field in our Country. They are recognized and registed by the Engineers Registration Board (ERB). Government is working on its promise of employing them to various irrigation schemes and relevant projects in the Local Government. A good number of them however have already been employed by other stakeholders. During the Graduation Convocation the Graduands resolved that at every graduation occasion each graduand should plant a memorial tree starting with their cohort.
The ATC staff are student centred, career focused and committed to student success. our hands-on (competence based) philosophy distinguishes ATC from many other technical institutions in Tanzania and the East African region. The College is confident that its graduates leave with a qualification which is respected in the industry with the competence and confidence that go with it.
The support of all stakeholders including students, Government, visiting lecturers/professors, Irrigation Experts and the College staff is highly appreciated and we count on your continued support and good cooperation.
Remember that always ‘Skills make the Difference!

Dr.Bilal added that development in science and technology was a crucial determinant of the processes governing national development and the country’s position in the global economy.
‘While developed countries are mulling over the post- industrial era, most African countries have not been able to adequately embrace even the
technologies of the first industrial revolution,’ the Vice President pointed out.
on his part, the Minister for education and Vocational training, Dr. Shukuru Kawambwa stated that technical and vocational education and training was the only vehicle which would enable African countries to reduce the gap between them and the first world countries as far as technology was concerned.
‘ it is indisputable that the contribution of TVET training in wealth creation is essential and if effectively utilized technical training graduates could be drivers of small and medium enterprise development’ said Dr. Kawambwa.
The Conference has been organized by Commonwealth Association of Polytechnics in Africa (CAPA) in conjunction with Arusha Technical College (ATC), National Institute of Transport (NIT) and Vocational Education and Training Authority (VETA).
‘Technological advancement in the case of Tanzania is particularly of major importance in the agriculture sector’ he said.

The Ministry of Energy and Mineral (MEM) in collaboration with the Tanzania Mineral
Dealers Association (TAMIDA) recently organized the 2nd Arusha International Gem, Jewelry and Mineral Fair (AIGMF) in which Arusha Technical College (ATC) fully participated.
In these exhibitions different institutions from Tanzania and outside Tanzania participated. ATC like many institutions used the exhibition as a means to disseminate information to the local and international Public on its newly introduced Course of Lapidary and Jewelry Technology.
The organizing Committee from ATC displayed different activities performed by students under this course including demonstration on how to cut and polish Gemstones, especially Tanzanite.
Speaking at ATC pavilion the College’s
Rector, Eng. Dr. Richard Masika told the Minister for Education and Vocational Training, Dr. Shukuru Kawambwa that the Institution intends to create local experts who will be able to add value to the diverse valuable gemstones explored in the Country
The Minister visited the pavilion where activities related to the College’s lapidary and Jewelry Training were
being displayed to an international delegation.
He lauded the College’s initiatives, pointing out that for many years mineral mined in the Country provided employment to the people in the other countries that could buy raw products only to cut and polish them in their own countries.
“This is a commendable initiative as the Country has a limited number of experts in this area. We want more people to have expertise in this area to add value to our mineral to make Tanzanians benefit out of this sector,’’ he said
The new Course has already been rolled out with the first batch of 16 students and is already enrolling new ones in an effort to boost the number of Jewelry Polishing experts in the Country.

ARgo lAb Introduced at ATC
Arusha Technical College (ATC) has unveiled a special ARGo system of Automotive engine diagnostic and repair workshop that is likely to change motor vehicle
repairing services in the country.
Speaking during the opening ceremony, the ATC Rector Engineer, Dr. Richard Masika said, the new advanced car that are extremely differently from old mechanical dilapidated vehicle means that the country’s mechanics and motor vehicle repair garages not equipped to handle them.
“older motor vehicles were mostly composed of mechanical parts with little, if any electronic, but new cars are automated, featuring mostly electronic and digital components with mechanical parts taking the back seat. Pointed out Dr. Masika
He added that the new ARGo lab at ATC will enable the new breed of mechanics to handle modern cars.
ATC has already developed a tailor- made automotive engineering curriculum which has been submitted to the National Council for Technical Education (NACTE) for approval.
Furthermore, the College has consulted the motor vehicle industry experts to see what they specifically wanted from the workforce who will be graduating from the programme.
ARGo project experts from Netherlands, Hendrick Jonkman and Sieberrn Idzenga are assisting in the maiden training scheme at the College pioneering the journey in digitalizing motor vehicle repairing in Tanzania.
The Hague based, PUM Netherlands senior experts organization is assisting ATC on the new ‘ Practical Training for Technicians’ Programme, the organization connects entrepreneurs in developing countries and emerging markets with senior experts from Netherlands that boast at least 30 years of experience in business environment .
With the newly established ARGo engine diagnostic laboratory and repair workshop at ATC, local car garages are set to be transformed from the old, smelly, oily warehouses full of spanners and blue-coat mechanics to modern centres featuring Lab like clean interiors fitted with Computers attended white- clad workmen who look like doctors.

A quick design method For SubSurFAcE conStructEd wEtlAndS For trEAtInG wAStEwAtEr
Experience has shown that both subsurface constructed wetlands work much better if preceded by a settling tank or a septic tank. They are suitable for secondary treatment- Second step in most waste treatment systems during which bacteria consume the organic parts of the wastes and further removal of suspended solids or tertiary treatment- Advanced cleaning of wastewater during which nutrients (such as phosphorous and nitrogen) and most suspended solids are removed).
Standard design of Horizontal Subsurface constructed wetlands
Design of horizontal subsurface flow constructed wetlands is guided by Kickuth Equation and media (gravel) characteristics giving a design equation below:
, where Ah is the surface area of the bed (m2),
Qd is the flow rate (m3/d), C
o is the influent organic
matters measured as BoD5 (mg/l) and Ce is the
effluent organic matters measured as BOD5 (mg/l).
KT is the temperature dependent factor (d-1), y is
media depth (m) and n is the porosity of the media (%). However K
Tyn = K
BoD =0.067-0.1
The design equation is suitably applied if at all possible to carry out a flow and load sampling survey.
Quick design of Horizontal subsurface constructed wetlands
In designing horizontal subsurface fowl constructed wetlands without prior information on characteristics of wastewater, a quick method is to use population equivalent (pe). With the following assumption
a) flow per person 40-200l/pe
b) BOD contribution (Co) 40-60g BOD5/pe and
c) Quality required (Ce) 10-20 mg/l (standard)
d) 20-45% of Co will be removed by pre-treatment system (e.g. septic tank)
Example
With an area of say with 200 people which requires horizontal subsurface constructed wetlands. The area of land required will be obtained as follow:
BoD5 flowing to pre-treatment system will be:
(60g/pe)/200 =300 mg/l and with assumption that 30% this BoD will be reduced at pre-treatment unit, Co = 0.7 x 300 – 210 mg/l
Qd = 200 pe x 200l/pe = 40 m3/d
Ah = [40ln (210/20)]/0.1 =940 m2
It is necessary to remember that:
a) Horizontal subsurface flow constructed wetlands are designed based on plug-flow assumption (l/w =1-5) and
b) In flow Qin
and out flow Qout are equal
c) Bed slope < 2%
d) Media depth should allow water to flow 0.15 m from the surface
INTRoDUCTIoN
Wetlands is land where the water surface is near the ground surface for long enough time to maintain saturated soil conditions
along with the related vegetation. They have partly oxic (oxygen condition), partly anoxic (anaerobic condition) soils in which organic breakdown takes place. Wetlands support a highly productive, tall emergent vegetable capable of taking up large amount of nutrients. There are two types of wetlands namely natural of constructed wetlands.
NATURAL WETLANDS
These have been used for wastewater treatment for many years. In many cases natural wetlands were used for disposal and not treatment and were considered as wastelands
Although improvement in the quality of wastewater is generally observed as a result of flow through natural wetlands, the extent of their treatment capability is largely unknown. In Tanzania natural wetlands occupy over 7% of the country’s surface area.
CoNSTRUCTED WETLANDS
These are Designed/man-made systems aimed at achieving removal of pollutants as observed to take place in natural systems. They are sometimes called Reed beds or artificial wetlands but constructed wetlands is an international term
Constructed wetlands are increasingly seen as a viable Eco-technology for wastewater treatment due to:
a) Public demand for more stringent wastewater effluent standards,
b) Rapidly escalating costs of construction and operation associated with conventional treatment plants, and
c) Environmental benefits
Classification of Constructed wetlands
These are:
a) Surface Flow Constructed wetlands (popular in USA particularly for Large wastewater flow: This is characterised by Wastewater being exposed to the atmosphere as it flows through the cell (treatment unit)
b) Subsurface constructed wetlands (Horizontal or vertical flow) widely accepted in Europe, Australia and Africa: This is characterised by Wastewater
being exposed to the atmosphere as it flows through the cell
Horizontal flow
Vertical flow
Processes (mechanisms) in treating wastewater by constructed wetlands
Treating of wastewater by Constructed wetlands involves transformation or removal of organics (BoD), suspended solids, nitrogen, phosphorus, pathogens and trace metals by:
a) Sedimentation: Gravity settling solids
b) Filtration: Particulate filtered mechanically as water passes through substrate, root masses etc.
c) Adsorption: Inter-particle attractive force
d) Biological microbial/metabolism: include nitrification/denitrification
e) Natural die off: Naturally decay or organisms in unfavorable conditions and
f) Plant absorption: Under proper conditions, significant quantities of these contaminants will be taken up by plants
Design of subsurface Constructed wetlands
This article will only discuss design of Horizontal subsurface constructed wetlands which have many advantages as compared to surface flow Constructed wetlands as indicated in the Table below:
SUBSURFACE FLoW SURFACE FLoW
Often greater operating cost
Generally lower installation costs
Clogging happensSimple hydraulic (no clogging)
More effective per unit area i.e. it needs less space

Auto-Trans.Vehicle“ECT /OD” Button Application.
ECT stands for “Electronically Con-trolled Transmission”. When you push the button in, there should be
a light on the dash board that indicates “ECT PoWER”. This changes the normal shift times (based on engine vacuum, rpm, and throttle position) to a later point.
This simply means that, the engine rpms will go higher before shifting to a higher gear when you’re accelerating. When engaged, the transmission shifts later, allowing the engine to get to a higher power level and accelerate faster. Gas mileage is usually reduced in this mode.
Use it only when you need to get up to speed faster; for example, to merge into fast moving traffic. The normal position for this switch is oFF.
In “Freelander vehicles” the button has “ECT/SNoW” mode. The “Snow” mode starts the transmission in 2nd gear rather than first so that the wheels don’t have quite as much torque and are less likely to spin in inclement weather. Secondly, it changes the whole shift pattern of the transmission, particularly when accelerating from a start or when passing. It has the transmission change into higher gears earlier so that, again, when it is bad
conditions you are less likely to spin the tires each time the transmission shifts up and when you go into a passing gear, it down-shifts only “one” rather than the usual “two” 2 gears so that you don’t have as dramatic a change in the power going to the wheels.
o/D stands for “over-Drive” this is a 4th gear on the transmission that will engage when you are going above about 35 mph/ 56kmh, that lets the engine operate at a lower speed (RPMs) when all it has to do is maintain a high speed when you are going over flat, even highway. This improves fuel economy.
Technically, any transmission gear with a ratio of less than 1:1 is considered “over-Drive”. o/D can normally be left “oN” except when going up a gradual hill where the overdrive tends to not give the engine enough power to maintain a steady speed. This may cause the transmission to annoyingly “hunt” between 3rd and 4th gear. When o/D is switched oFF there should be a light on the dash board that says “o/D oFF”.
o/D oFF essentially suppresses the automatic shifting on your car, and lets you use the gears as if it were like a manual (note, like a manual,, but not exactly). For instance a vehicle is a 4-gear auto transmission and have D, 2 and L; so if the button O/D (switched off) engaged, L = 1st gear, 2 = 2nd gear, D = 3rd gear, and the 4th gear is only engageable if you switch the button on. otherwise each of these are the ‘highest’ gear your car will go in, but it will drop to a lower gear if necessary. (o/D oFF, and the gear lever is in ‘2’ position, this will limit you to the 1st and 2nd gears of your auto transmission)
Instructions on the use of (o/D oN)
1 Press the button when passing another car on the highway. When
passing another vehicle in an automatic transmission car, it is sometimes difficult to get the car to accelerate fast enough. Try clicking the overdrive button. By forcing the car into third gear, your engine will gain more toque and thereby
be better able to accelerate past the other car.
2 Press the button when entering the expressway. As explained above, this
will make it easier to efficiently accelerate up to cruising speed.
3 Engage the button when exiting the expressway. Click the button just as you turn onto the exit ramp, and let the engine help slow you down. Brakes have a greater tendency to overheat when used at high speed. Using the o/D lockout button will help to slow you down to a lower speed, at which point you can use your brakes.
4 Press the button when going up a long, shallow grade on the expressway. In
such situation, sometimes the automatic transmission will fail to shift down soon enough, causing you to lose power. Engage the o/D lockout to force the car into third gear.
5 Engage the o/D lockout button when going down a long hill to help keep
you from gaining too much speed. If the hill is steep, you may even need to shift the car down into second gear with the shifter. This will help prevent overheating your breaks.

The path begins with an open field and we walk amongst the herd of buffaloes. The guide insists that
they do not attack as a group but one should be cautious of a lone buffalo for they are prone to charging and in such instance one must lie down and not run away. You cannot outrun a buffalo, he insists. He then ordered us to follow what he says, as he quotes some
statistics indicating that the highest attacks caused by animal on human are from buffaloes. Our hearts start beat very fast and our steps become light.

Mzee Makumulo, and rehemael Anael, ) We call ourselves the winning team and some of us mock the mountain that they will climb it for a day instead of three or four days as we hurry away from the open field up a small incline that is forested and full of mysterious plants that the guide knows by names, indicating their usage.
We go through a series of grassy walkways and forested inclines and finally encounter a river. The river runs silently, no sharper sound to it as what we would expect of buzzing of the bee. Trees surrounded the forest, giving it an indistinct feeling.
Steeper route
the route runs steep and our stories and laughter fade, it become harder to stare at the environment and we end up watching our steps, mindful to stay on the track and not to deviate into the bush.
As we start to wonder when we shall arrive at the first Hut we see a wooden backyard stand peeping above us and we
are relieved. We have reached Miriakamba Hut
As we start to wonder when we shall arrive at the first Hut we see a wooden backyard stand peeping above us and we are relieved. We have reached Miriakamba Hut
Day 2
The next day we assemble at the start of the next route we pray and start our next journey. We climb to the big valley, then up to the saddle area. our goal is Saddle Hut. There we will relax for a while and then continue hiking up to Little Meru. We stay overnight in Saddle hut and sleep early because we will get up again very soon.
We will have hiked about 5 hours and reached a height of 3570m by the end of the day.
Summit Day
We get up at midnight and after a light breakfast we are ready for our ascent to the summit. The trail is steep and rocky it will take us 5-6 hours to reach Meru Peak, the second highest peak in Tanzania at 4566m.
Finally after, a series of seemingly endless climbs we finally saw the flag and our energy was revived.
We thank God for making us reach the Top as there was no sign of human life and none of his sounds , except ours, just the sky, the sun, the sea of cloud under our feet, Mt Kilimanjaro to the east and our mountain Meru. Seeing all these splendid stuff; we glorify God for his wonderful works.

Q: Tell us about your early life?
A: I was born in 1961 at Nyaburundu village in Musoma, Mara region. I started standard one- 1972-1978 at Gongoni Primary School in Tabora. In 1979-1982 I joined Ifunda Technical Secondary school, a special school by then where I took Mechanical Engineering with specialization in Automotive Engineering.
In 1983-1986, I joined the then TCA (Now ATC) where I took Automotive Engineering. In 1986-1987, I joined JKT at Massange in Tabora for National Service. Thereafter, I joined TANAPA as senior Technician in Automotive Department at Serengeti National Park in 1987.
In 1989 I rejoined TCA (now ATC) not as a student but this time as a Grade IIIA teacher. I went for further studies i.e. diploma course in Technical Education at Dar es Salaam Technical College (DTC).
Between 1991-1993 I went to Germany for Advanced Training in Automotive Engineering. Upon my return to Tanzania in 1993, I went to
Complete Diploma in Technical Education at Klerru Teachers’ Technical Colle
In 2002-2005, I returned at Dar es Salaam Institute of Technology (DIT) to take advanced Diploma in Mechanical Engineering then for Bachelor’s Degree in Automotive Engineering at National Transport Institute (NIT) between 2009-2013.
Currently, I’m a Workshop Manager in the Automotive Engineering Department
at Arusha Technical College.
Q2: What are your tasks at Arusha
Technical College?
I’m still teaching at the department of Automotive, planning and s u p e r v i s i n g all activities at
the Automotive E n g i n e e r i n g
workshop. Also, I provide consultancy
services in the automotive field at the College.
Eng. Joseph Kottini is one of the alumni of the Arusha Technical College formerly known as Technical College Arusha (TCA). He graduated in 1989 with full Technician Certificate in Automotive Engineering. Our staff writer Gasto Leseiyo interviewed him recently on his experiences at ATC.

Eng. Kottini: Automotive dream realized
Q3: Why did you choose to major in automotive engineering and noT in any other technical discipline?
“It is simple. When he was young I was interested more in cars and my dream was to become a driver. It reached a point when I was dreaming to make a car that could fly like aero plane. In short I can say automotive engineering was flowing in my blood’’.
Q4: Have you ever thought of giving up?
“In my entire life is all about struggling. I’ve never given up and my above short history can justify what I’m telling you”.
Q5: is there any challenge in your daily activities?
“Yes! Managing such a huge automotive workshop someone has to burn the candle in both ends. It is very hectic because all students from first year to third year need to pass in the automotive workshops for skills acquirement. But I thank God that I can handle this and other challenges because at ATC we work as a team.’’
Q6: A word to students willing to become automotive engineers
Vehicles need people who are careful because they carry people and valuable property. Automotive industry needs youths because it keeps changing every day due to advancement of technology and other innovations hence they’ve to work hard if they want to realize their dreams.

Higher learning education institu-tions in Tanzania have the role to produce specialists of different
fields. Moreover, the institutions have great chances to solve various challeng-es that face this nation. For this reason, Arusha Technical College (ATC) has suc-cessfully used skills and knowledge of its students and their lecturers to innovate simple technologies to solve the elec-tricity shortage in rural setting.
Engineer Urbanus Melkior is the Head of Electricity Engineering Department at the College who believes that if stu-dents and their academicians work to-gether they can solve the electricity problem facing many villages in Tanza-nia. In translating this idea into reality, the engineer says that, ATC has come up with a simple machine for produc-ing electricity which has been branded as ‘Mini hydro Turbines. The good news
about this technology is that, amid the shortage of water on the earth surface, it uses very little water to generate pow-er!

“In the year 2011 there was a great power blackout. It was a time when people Could stay for up to 11 hours with no electricity. This was actually what made us to think about the solution for this prob-lem,” says the Head.
Explaining the process-es that ena-bled this idea to materialize, Eng. Melkior says his Department in collaboration with Mechanical Engineer-ing Department managed to come up with the ma-chine which was installed at Makumira in Arumeru district.
The Mini hydro Turbines, ac-cording to Eng. Melkior, can produce electricity using little water. To assure how effective the technology is, estimated 20 households are beneficiaries of this simple technology.
“What we are doing is to Construct the machine and install where there is a need. After that, we handover to the vil-lagers to operate and maintain it,” he adds.
“After installing the machine, the next activity is to let water enter in it or re-duce water from it. Also the care taker of machine should make sure that the fric-tion part of machine is lubricated. Any-body can do this works,” he explains.
Apart from Makumira, other areas

The motive behind
The innovation of the machine which has proved to be more
economical for the lower income com-
munities in the rural setting
has motivat-ed students to invent
variety of technolo-gies pur-posely to help the s o c i e t y. “In our d e p a r t -
ment, we have 18
s t u d e n t s who have
chosen to be-come innovators.
After class hours, they remain at the
workshop, scratching their heads to come up with
something tangible that can help the community,” says the
engineer.
He adds, “… now they have in-vented the device that can kill mosquitoes, device for searching minerals and a simple technol-
ogy for producing chickens.”
The Head of Department believes that students are doing great because they have been given freedom. When the freedom is used effectively, something great can be invented; indeed the ATC students are devoted to do so for the community’s betterment.
Engineer Melkior went on explaining the plans to encourage innovation in Electrical Engineering Department by saying, since the beginning of this se-mester, every student is required to in-
novate anything that when sold, can cover all cost of his/her tuition fees.
According to him, this initiative will not only help students while they are at the campus but also after their studies at ATC. The innovation spirit, according to the academician, will refute the mindset of most of graduates that employment is everything and embark on self-em-ployment because they can innovate.

Three Engineers
There are three engineers in a car: an electrical engineer, a chemical
engineer and a Microsoft engineer. Suddenly the car engine shuts off, leaving the three engineers stranded by the side of the road. All three engineers looked at each other wondering what could be wrong. The electrical engineer suggests stripping down the electronics of the car and trying to trace where the fault might have occurred.
The chemical engineer, not knowing much about cars, suggests that maybe the fuel is becoming emulsified and getting blocked somewhere.
Then, the Microsoft engineer, not knowing much about anything, comes up with a suggestion, “Why don`t we close all the windows, get out, get back in, open the windows again, and maybe it`ll work!?”
An Engineer and a Lawyer
An engineer and a lawyer attended an interview separately. the Engineer was asked:
“If ten men cleared one hectare of land in ten hours how many hours would five men require clearing the same piece of land?
the engineer answered: “If ten men cleared one hectare for ten hours, then one man would re quire 10 X 10 hours. Therefore five men would require 10x10 divided by 5 i.e 20hours.”
the lawyer was asked the same question and he answered: “If ten men cleared one hectare of land for ten hours, then there would be no piece of land for any man to clear. Therefore five men would require zero hour.”

There is no doubt that, water has be-
come a very crucial element vital to
life on earth. Every farmer, weather
small-scale or larger- scale knows quite
well that if there is no water, there are no
plants growing and so there is no food.
Water is therefore an essential resource to
farmers. Its management to a great extent
determines how successful a farming
enterprise is or can be. Many farmers in
Tanzania and Arusha in particular depend
on rain to satisfy the water requirements of
their farms.
Unfortunately due to the climatic changes
fuelled by global warming, this rainfall is
often low, erratic and unreliable and since
water availability is the limiting factor
to plant growth. Indeed, this is a time
farmers get involved into alternative way
to minimize risks on rain-fed agriculture.
More and more farmers need to be aware
of these problems and installing irrigation
systems on their farms.
The most reliable and more economical
irrigation technology is Drip Irrigation, a
highly efficient way to water; it saves time
and helps to conserve precious supplies
of clean water. Studies show that a well-
designed drip system uses at least 30
percent and in some cases 50 percent
less water than other methods of watering
such as sprinkling. This is because a drip
Irrigation system delivers water directly to
the root zone of the plant, where it seeps
slowly, into the soil, one drop at a time.
Almost no water is lost through surface
runoff or evaporation and soil particles
have plenty of opportunity to absorb and
hold water for plants. It also means very few
nutrients leach down beyond the reach of
the plant roots.
Furthermore, since drip irrigation delivers
water directly to the plant less water is
wasted on weeds. The water surfaces
between the plants also remain drier, which
discourages weed seeds from sprouting.

Drip Irrigation: every drop countsWHy DRIP IRRIGATIoN?
Drip irrigation permits you to produce
crops the whole year-much more than
the rain fed irrigation it has many other
advantages such as:
• It is very efficient; this is because
water soaks into the soil before it can
evaporate or run off
• Water is supplied to the soil around
the plant. This means that less water is
wasted, while high moisture conditions
are maintained close to the roots of
the plant. This makes drip irrigation
appropriate for area where water is
scarce.
• Drip Irrigation is easy to install and
can be inexpensive if locally available
material are used
• It allows you to add soluble nutrients
into the water, so they can be fed
directly. This economizes on your
fertilizer use.
• It gives a higher yield because you can
plant on both sides of the pipe
• It helps reduce diseases associated with
excess moisture on some plants
• Drip irrigation can be used in fields that
have uneven landscape
• It decrease weed populations. Since
water is applied close to the roots of the
plants, the soil surface between rows is
dry, so the weeds cannot grow.
• The drip irrigation system does the
watering without labor and reduces
costs
Criteria for choosing Drip Irrigation
system for small scale farmers
Using clean water is very important in Drip
Irrigation. Water from the ponds, rivers and
wells may contain some particles that can
block the holes that release water to the
plants. Hence it necessary to have filter to
remove these particles. The best way, for
small scale farmers who cannot afford to
own filter at beginning, is to let water run
through a piece of cotton or socks when
filling the bucket or drum.
THE BUCKET KIT SySTEM:
This system is ideal for growing vegetables
in small home gardens during the long dry
season. The bucket kit consists of fittings
and 30 meters of irrigation drip tape
connected to a 20 litre bucket. The bucket
is placed at least 1 meter above the ground
so that the gravity provides enough water
pressure to ensure even water for the
entire crop.
Water is poured into the bucket twice
daily and passes through a filter, it fills the
drip tape and evenly distributed to 100
watering points. The multi-chambered
plastic drip tape is engineered to dispense

water through openings spaced at 30 cm.
A seedling is planted at each wet spot so
that all the moisture is absorbed directly
by the plant roots.
THE DRUM IRRIGATIoN SySTEM
The drum system will cover a garden 6.5
metres wide and 16 metres long. The drum
kit is used to cover five planting beds and
therefore the plant population depends on
the type of crops grown. Water is supplied
from a 200-litre drum that is fixed on a
platform at a height of at least 1 metre
above the ground.
THE 1/8 FARM SySTEM
This system covers 1/8 of an acre (a
15 metre x 30 metre plot). A platform
2 metres high is constructed to create
enough water pressure. A drum with a
capacity of 1000 litres would be ideal to
supply enough water per day.
RECoMMENDATIoN To THE
GoVERNMENT:
Since water has become a scarce
commodity, Government through the
Ministry of Agriculture can introduced
cost sharing for farmers in
the installation of drip/micro
irrigation systems. This will
improved crop yield, less
applied water and will reduce
subsurface draining water
and surface tail water. Hence
benefits farmers.

National Council for Technical Edu-
cation (NACTE) has so far regis-
tered 323 technical institutions
which offer technical skills from NTA level
4 to 8. These institutions have developed
their own curriculum after conducting
situation analysis for the skills that will be
offered.
Also NACTE validates the curricular
as well as recognizing the capacity for
these technical institutions in running
the programs. Furthermore, Ministry of
Education and Vocation Training, through
its directorate of Vocational Training, has
so far registered 819 both public and
private VET providers.
Most of these technical and VET
(TVET) institutions have workshops
and laboratories which were equipped
in 1990’s. Today there is a number of
advancement in technology with more
less or no investment in workshops and
laboratories training facilities which
resulted in the production of graduates
with skill gaps. The skill gaps force our
graduates to seek jobs rather than
creating jobs for others, consequently
resulting to unemployment situation for
the most of them.
Tanzania is losing large amount of
domestic revenue due to importation of
substandard and counterfeit products.
Popular counterfeit products include
cloths, mobile phones, building material
and foot-wear. others that may be
harmful as recognized worldwide are
human and veterinary pharmaceuticals,
electrical goods, specialized technical
items and components, cosmetics, eye-
wear including sunglasses. Most of these
counterfeit products are not necessarily
imported but can be fabricated in the
country only if the TVET institutions train
using high Tech training facilities as well
as researching on small machines which
should increase employment in terms of
value addition to products.
As trained and skilled TVET graduates
Role of technical institutions inpromoting innovations
migrate from rural to urban area each year
the production in the area declined. Also
the products produced are not processed
(Value added) hence are sold at a low
price which cannot meet production cost
leaving rural residents in poverty.
The Government through TVET has
to do research on small machines like
packaging machines, milling machines,
milk and food processors, shoes making,
and others for value addition to farm
products. These value addition machines
have to be installed at least at district level
for value addition creating employment
hence stopping migration of people from
rural to urban and increase income from
agricultural products.
Further to that, TVET institutions
have to train the graduates on Biogas
technology. The Government has to
promote it by paying construction
cost while the farmers have to buy
construction material. These will attract
the TVET graduate to go back to their
villages promoting biogas technology as
the major source of energy for lighting
and cooking and income generation to
them. These will save sources of water
and forest hence conserving the nature
(no one will cut trees for lighting and
cooking).

Solar Power in TAnzAniA:Engine for people centered economy
Life without electricity might feel like prophetic relation or so called the end time scenario or to the end of the
world in general, but for those living in rural Tanzania it is a fact of everyday life. Accord-ing to Ministry of Energy figures of February, 2014, only 24% of the Tanzania population has access to electricity, rural areas are vir-tually disconnected from the National grid.
As we know, for any development to take place electricity is very important and the evidence is before our eyes every day. Business requires a steady supply of energy to produce goods and services electricity allows school children to study after sun set and hospitals need it to save lives. Insufficient or irregular energy supply is associated with significant economic cost for business and households. Lack of access to clean energy also creates myriad of health and environmental hazards such indoor pollution from cooking on traditional open- fire stoves and deforestation.
benefiT of solAR PoWeR:
Solar energy can be well established in many rural areas and can be
used for power generation, water heating, detoxification, telecommunications and transport at an industrial level; water pumping, vaccine refrigeration and electrification; lighting, cooking and running of modern appliances at domestic level.
With the potential to enhance both social and economic aspects of village
life in remote areas, rural solar electrification faces very
different challenges to those faced by urban
projects. Food preservation and pumping systems reduce hunger and improve access
to safe drinking water respectively.
Recent solar-panel cost reductions have
broadened the range of economical applications for solar water pumps, enabling farmers to irrigate crops.
Following successful implementation, solar-powered lighting enables shopkeepers to conduct business for longer time without resorting to dangerous, naked-flame light sources. Schools and clinics can run refrigeration and telecommunications. Rural electrification means that residents can safely gather during the hours of darkness and children can study longer. Communities can power perimeter security and support emergency medical care.
Workshops, small scale industry can be built as a result of increasing job opportunities in the rural setting. This can however avert the current rural-urban migration trend because young people who majority are unemployed in urban can stay in their respective areas and engage in production.
