The Project for Capacity Building in Irrigation Development (CBID)
Foreword Oromia Irrigation Development Authority (OIDA) is established on June, 2013, as a responsible body for all irrigation development activities in the Region, according to Oromia National Regional Government proclamation No. 180/2005. The major purposes of the establishment are to accelerate irrigation development in the Region, utilize limited resources efficiently, coordinate all irrigation development activities under one institution with more efficiency and effectiveness. To improve irrigation development activities in the Region, the previous Oromia Water Mineral and Energy Bureau entered into an agreement with Japan International Cooperation Agency (JICA) for “The Project for Capacity Building in Irrigation Development (CBID)” since June, 2009 until May, 2014. CBID put much effort to capacitate Irrigation experts in Oromia Region through several activities and finally made fruitful results for irrigation development. Accordingly, irrigation projects are constructed and rehabilitated based on that several Guidelines & Manuals and texts produced which can result in a radical change when implemented properly. Herewith this massage, I emphasize that from Now on, OIDA to make efforts to utilize all outputs of the project for all irrigation activities as a minimum standard, especially for the enhancement of irrigation technical capacity. I believe that all OIDA irrigation experts work very hard with their respective disciplines using CBID outputs to improve the life standard of all people. In addition, I encourage that all other Ethiopian regions to benefit from the outputs. Finally, I would like to thank the Japanese Government, JICA Ethiopia Office, and all Japanese and Ethiopian experts who made great effort to produce these outputs.

Introductory Remarks “Growth and Transformation Plan” (GTP) from 2011 to 2015 intensifies use of the country’s water and other natural resources to promote multiple cropping, better adaptation to climate variability and ensure food security. Expansion of small scale irrigation schemes is given a priority, while attention is also given to medium and large scale irrigation.
In Oromia Region, it is estimated that there exists more than 1.7 million ha of land suitable for irrigation development. However, only 800,000 ha is under irrigation through Traditional and Modern irrigation technology. To accelerate speed of Irrigation Development, the Oromia National Regional State requested Japan International Cooperation Agency (JICA) for support on capacity building of Irrigation Experts under Irrigation Sector.
In response to the requests, JICA had conducted "Study on Meki Irrigation and Rural Development" (from September 2000 to January 2002) and Project for Irrigation Farming Improvement (IFI project) (from September 2005 to August 2008). After implementation of them there are needs to improve situation on irrigation sector in Oromia Region.
JICA and the Government of Ethiopia agreed to implement a new project, named “The project for Capacity Building in Irrigation Development” (CBID). The period of CBID is five years since June, 2009 to May, 2014 and main purpose is to enhance capacity of Irrigation Experts in Oromia Region focusing on the following three areas, 1) Water resources planning, 2) Study/Design/Construction management, 3) Scheme management through Training, On the Job Training at site level, Workshops, Field Visit and so on and to produce standard guidelines and manuals for Irrigaiton Development.
These guidelines and manuals (Total: fourteen (14) guidelines and manuals) are one of the most important outputs of CBID. They are produced as standards of Irrigation Development in Oromia Region through collecting different experiences and implementation of activities by CBID together with Oromia Irrigation Experts and Japanese Experts.
These guidelines and manuals are very useful to improve the Capacity of OIDA Experts to work more effectively and efficiently and also can accelerate Irrigation Development specially in Oromia Region and generally in the country.
Finally, I strongly demand all Irrigaiton Experts in the region to follow the guidelines and manuals for all steps of Irrigation Development for sustainable development of irrigation.

2. Creating Color Composite Imagery using ILWIS 3.4
2.1 About Color Composite Imagery
(1) LANDSAT ETM+
Basically, satellite data consists of several bands from visible to infrared
wave band. For instance, LANDSAT ETM+ data has eight (8) bands as
follows;
Band 1 to Band 3 are visible band, Band 4 is near infrared, Band 5 and
Band 7 are short wave infrared, Band 6 is thermal infrared and Band 8 is
panchromatic mode. And using visible bands and near infrared band,
some color composite imageries can be produced.
In Remote Sensing, there are three (3) kinds of color composite imagery,
such as “False Color Composite Imagery”, “Natural Color Composite
Imagery” and “True Color Composite Imagery”. And false color composite
imagery is often applied for the land use classification analysis because
this composite imagery contains the near infrared band. In addition, the
near infrared is very useful to identify the vegetation area. Therefore, the
false color composite imagery is widely used for the land use
classification. And the band assembly to produce the three (3) color
composite imageries is shown below.
Color Composite Red Green Blue
False Color Bnad 4 (N.I.) Band 3 (V.R.) Band 2 (V.G.)
Natural Color Band 3 (V.R.) Band 4 (N.I.) Band 2 (V.G.)
True Color Band 3 (V.R.) Band 2 (V.G.) Band 1 (V.B.)

(2) SPOT 5 Data
SPOT 5 data can be purchased at EMA (Ethiopian Mapping Agency).
SPOT 5 has three (3) kinds of sensor, such as HRVIR-M, HRVIR-X and
VEGETATION. And resolution of each is 5m, 10m and 1km. Basically,
HRVIR-X data is used for the land use classification analysis if your study
area is not huge.
In case of using SPOT 5, the band assembly to create color composite
imageries is shown below. About true color composite imagery, it is
impossible to generate using HRVIR-X data because it does not have
Visible Blue band. However, in case of using VEGETAION data, it can be
generated.
Color Composite Red Green Blue
False Color Band 3 (N.I.) Band 2 (V.R.) Band 1 (V.G.)
Natural Color Band 2 (V.R.) Band 3 (N.I.) Band 2 (V.G.)
True Color Not Available (in case of HRVIR-X)
Band 3 (V.R.) Band 2 (V.G.) Band1 (V.B.)

3. Land Use Classification Analysis (Supervised Classification)
3.1 About Supervised Classification
A supervised classification is the most popular classification method in
Remote Sensing. The concept of the supervised classification is shown
below.
Basically, in the supervised classification method, the satellite image
data can be classified based on the statistical data of the training sample
data. And the procedures for supervised classification are as follows;
Definition of land use classification item
Preparation of training sample data
Arrangement of training sample data
Evaluation of training sampling data
Classification
Validation of the results of classification

3.2 Definition of Land Use Classification Item
Before starting land use classification analysis, land use classification
items have to be define based on the characteristics of false color
composite imagery and true color composite imagery. Basically,
following land use classification items can be identified on the LANDSAT
ETM+ data.
