Message from the Rector

First Irrigation Engineering Graduates Enter the Market in Style 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.

Eng. Dr. Richard J. Masika Rector

t 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

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 Demonstration within the ATC field irrigation irrigation and

support teaching, a Farm was constructed campus to demonstrate techniques for gravity 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!

Atc participates in the 2nd

Arusha International Gem, Jewelry and Mineral Fair (aigmf) By Gasto Leseiyo

he 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

A quick design method

for subsurface constructed wetlands for treating wastewater By Senzia, M.A.(PhD)

Introduction

etlands 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

being exposed to the atmosphere as it flows through the cell

Standard design of constructed wetlands Horizontal flow

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

Subsurface

, where Ah is the surface area of the bed (m2), Qd is the flow rate (m3/d), Co 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 KTyn = KBOD =0.067-0.1

Constructed wetlands

Constructed wetlands are increasingly seen as a viable Eco-technology for wastewater treatment due to:

Horizontal

Design of horizontal subsurface flow constructed wetlands is guided by Kickuth Equation and media (gravel) characteristics giving a design equation below:

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 countryâ&#x20AC;&#x2122;s surface area.

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

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).

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.

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

BOD contribution (Co)

40-60g BOD5/ pe and

include

Quality required (Ce)

10-20 mg/l (standard)

e) Natural die off: Naturally decay or organisms in unfavorable conditions and

20-45% of Co will be removed by pretreatment system (e.g. septic tank)

c) Adsorption: Inter-particle attractive force d) Biological microbial/metabolism: nitrification/denitrification

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:

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 â&#x20AC;&#x201C; 210 mg/l

Subsurface Flow

Surface flow

Qd = 200 pe x 200l/pe = 40 m3/d

Often greater operating cost

Generally lower installation costs

Ah = [40ln (210/20)]/0.1 =940 m2

Clogging happens

Simple hydraulic (no clogging)

More effective per unit area i.e. it needs less space

Needs More space (land)

No/Less odour

Odours is likely to happen

c) Bed slope < 2%

Possibly fewer mosquitoes

Possibly more mosquitoes

d) Media depth should allow water to flow 0.15 m from the surface

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

The Rector and the ATC community at large is taking this opportunity to thank and congratulate the Italian government through the TELMS Project Manager, Dr. Daniele Passalaqua for taking a leading role in ensuring ATC is fulfilling its Vision and Mission..

Auto-Trans.Vehicle “ECT /OD” Button Application. By David Raymond

CT stands for “Electronically Controlled 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 “OverDrive”. 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)

be better able to accelerate past the other car.

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.

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.

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.

Instructions on the use of (O/D ON)

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 NOVEMBER - APRIL 2015 atc Newsletter

Mount Meru â&#x20AC;&#x153;Pole, poleâ&#x20AC;? the guide chants as we start our Journey facing the slopes of Mount Meru. It starts with buffaloes; dark, short and endless captivate stares. By Gasto Leseiyo

he 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. We are group of 13.

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.

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

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.

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

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.

Success Story

Eng. Kottini: Automotive dream realized 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. 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.

hydro-power generator “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 problem,” By Gasto Leseiyo

igher learning education institutions in Tanzania have the role to produce specialists of different fields. Moreover, the institutions have great chances to solve various challenges that face this nation. For this reason, Arusha Technical College (ATC) has successfully used skills and knowledge of its students and their lecturers to innovate simple technologies to solve the electricity shortage in rural setting.

Engineer Urbanus Melkior is the Head of Electricity Engineering Department at the College who believes that if students and their academicians work together they can solve the electricity problem facing many villages in Tanzania. In translating this idea into reality, the engineer says that, ATC has come up with a simple machine for producing 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 power! Cross –flow turbine Runner fabricated at ATC Mechanical Engineering Workshop “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 problem,” says the Head. Explaining the processes that enabled this idea to materialize, Eng. Melkior says his Department in collaboration with Mechanical Engineering Department managed to come up with the machine which was installed at Makumira in Arumeru district. The Mini hydro Turbines, according 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 villagers to operate and maintain it,” he adds.

“After installing the machine, the next activity is to let water enter in it or reduce water from it. Also the care taker of machine should make sure that the friction part of machine is lubricated. Anybody can do this works,” he explains. Apart from Makumira, other areas

where such technology is installed are Morogoro, Iringa , Katavi, Njombe and Ruvuma. A Min- hydropower Turbine designed by ATC under Performance test The motive behind The innovation of the machine which has proved to be more economical for the lower income communities in the rural setting has motivated students to invent variety of technologies purposely to help the s o c i e t y. “In our department, we have 18 students who have chosen to become 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 invented the device that can kill mosquitoes, device for searching minerals and a simple technology for producing chickens.”

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-employment because they can innovate.

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.

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.

Drip Irrigation: Willison Munenwa

every drop counts

By Gasto Leseiyo

here is no doubt that, water has become 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 welldesigned drip system uses at least 30 percent and in some cases 50 percent less water than other methods of watering NOVEMBER - APRIL 2015

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. atc Newsletter

Drip Irrigation: every drop counts Why 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.

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.

Role of technical institutions in

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.

promoting innovations By Urbanus Melkior

ational Council for Technical Education (NACTE) has so far registered 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 1990â&#x20AC;&#x2122;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, eyewear 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

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).

ife 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. According to Ministry of Energy figures of February, 2014, only 24% of the Tanzania population has access to electricity, rural areas are virtually 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
