KMDP has built up rich knowledge and experience as regards good practice forage production and preservation for smallholder, medium and large scale dairy farms (from seed to feed). In addition to that, it has successfully piloted commercialization of quality forages and of forage contracting services. This was achieved through the SPEN model and the concept of “maize train” (i.e. mechanized agricultural contracting services for maize production, harvesting and silage making), and by facilitating introduction of innovative machinery for making baled silages. Through replication and upscaling, this will ensure enhanced access of quality forages for small medium and large-scale dairy farms.
In 2018 KMDP-II also started a pilot on introduction of feed rationing software to help optimizing total rations and margin over feeds. KMDP participates in sector platforms that discuss forage availability in Kenya and supported the National Fodder Conference in Nakuru in December 2017 and the Animal Production Society in Nanyuki in March 2018

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

5. SRI: Historical background
• SRI was developed in Madagascar in the 1980s
through efforts of Fr. Henri de Laulaniè
• The System was developed slowly through farmer
experimentation, changing water application
techniques, crop spacings, and seedling age etc.
• Rice yields increased from 2 t/ha to 10, 12, even Fr. Henri De Laulanié
14 t/ha.
• Prof. Norman Uphoff helped out-scale SRI to other
countries
• SRI has been grown in
Madagascar , India, Philippines, Cambodia, Laos, Sri
Lanka, Sierra
Leone, Bangladesh, Gambia, Cuba, Nepal, Myanmar, Prof. Norman Uphoff
Thailand, Mali, Rwanda, …..
• Kenya was the 37th country in the world to adopt
5
SRI in 2009
6. What is SRI?
• SRI is a package of practices especially
developed to improve the productivity
of rice grown in paddies.
• Unlike the conventional method of
continuous flooding of paddy
fields, SRI involves intermittent
wetting and drying of paddies as well
as specific soil and agronomic
management practices.
What SRI is NOT
• SRI is not about growing upland rice
varieties
• SRI is not GMOs
• SRI does not modify the genetic 6
7. Components of SRI
SRI has seven major components (deviating from
conventional flooded paddy)
1. Transplanting very young seedlings, i.e., at 8 to 12
days old (instead of the conventional 3-4 weeks)
2. Raising the seedlings in un-flooded nurseries and
well-supplied with organic matter
3. Transplanting seedlings at wider spacings and in a
square pattern, usually 25x25 cm, giving roots and
leaves more space to grow
• Transplant seedlings quickly, carefully and shallow
– taking care to have minimum trauma to roots,

8. Comparing conventional paddy nursery with SRI practice
SRI requires
less seed
SRI dry nursery, and 8-day old seedling
Conventional flooded nursery
Transplanting conventional rice seedlings Transplanting SRI young seedling
9. Components of SRI contd…
4. Transplanting only one seedling per hill (NOT of clumps of
3-4 seedlings)
5. Alternate wetting and drying of the paddy field
(do not continuously flood the soil) to ensure aerating
of the root zone,
6. Weed control is preferably done with a simple
mechanical rotary weeder. This aerates the soil as
it eliminates weeds, giving better results than
either hand weeding or herbicides,
7. Providing as much organic matter as possible to the
soil.

10. Comparing conventional paddy with SRI Practice

11. Advantages of SRI - More yield for less inputs
1) SRI gives higher rice yields – compared
to conventional flooded paddies,
2) SRI requires less water, and can save
25-50% water used in irrigation
3) SRI uses less seed & farmers save up
to 80% of the cost of seed
4) SRI rice has a harder grain, thus less
breakage during milling, giving better
grain quality and higher price.
5) Nearly all rice varieties give higher
yield with SRI, but some high-yielding
varieties respond better than others.

13. Background to SRI efforts in Kenya
• SRI was introduced in Kenya at the Mwea Irrigation Scheme in July 2009
• Initial partners: JKUAT, NIB, AICAD, WB, WBI, MoA, MWI, KARI, Cornell
University (of USA), Mwea Irrigation Scheme/MIAD, farmers
• The first crop season Aug 2009-Jan 2010, only two pioneer farmers
accepted to do trials voluntarily & on-station research trials at MIAD –
supported by AICAD
• Within that time, training & awareness creation was done using the two
farmer trials, video conferences, special ladies’ training
• Jan-May 2010: farmers were trained by invited trainers from India &
Japan supported by World Bank Institute
• Since April 2010, JKUAT Innovation Fund has been supporting a 3-year
SRI research & capacity building project in Mwea.
• From June 2011, National Irrigation Board is supporting a 6-month
project to upscale SRI in 4 schemes, i.e., Ahero, West Kano, Bunyala
& Mwea.
15. Objectives of the SRI initiative in Kenya
The main objective is to facilitate the wide-scale adoption of SRI for
increased rice productivity, water savings and occupational health.
The specific objectives include to:
• Promote adoption of SRI for improved rice production
• Save water used in irrigation of paddy rice.
• Scientifically assess the adaptability of SRI in Mwea and other rice-
growing areas in Kenya
• Quantify the benefits of up-scaling SRI
• Determine the health and environmental impacts of SRI, e.g., effects
on mosquito survival
• Create awareness/advocacy for SRI among key stakeholders engaged
in the rice value chain (farmers, Government staff, private sector)
• Build the capacity of important actors (farmers, extension
workers, researchers).

• Video conferencing
• Displays in the Nairobi
International Show
• Exchange visits for farmers &
staff
• Media outings
• Radio broadcast/adverts
• Engaging private
sector, e.g., Numerical
Machining Complex, compost-
making NGOs
• Over 10,000 individuals reached
with SRI message
25. Extending SRI to Western Kenya
• SRI project launched in
Ahero, West Kano and Bunyala
• SRI Training of Trainers in MIAD
for all schemes
• Video conferencing for Western
Kenya farmers linking with
India, Philipines, Mali (WBI)
• Exchange visits between the
four groups of farmers
• This project is set to expand to
SW Kano (5 schemes this year)
27. Results show that SRI works!
Key findings – based on Research & SRI farmer crop of Dec. 2011
Conventional paddy SRI Rice
1. Basmati yields : 4 – 5 t/ha 1. Basmati yields : 7 – 10 t/ha
(Mwea) 2. BW rice yields: 11 - 20 t/ha
2. BW rice yields : 7 - 10 t/ha 3. Bag of paddy weighs 100-110 kg
3. A bag of paddy weighs 80-90 kg 4. Harder, not easily broken on
4. Water to grow 1 kg of rice: milling
3,000-5,000 litres 5. Uses 25-33% less water
5. Grain easily breaks during milling 6. SRI has strong stems that resist
6. Flooded paddies suffer lodging
damage from windy storms
from windy storms
7. Wedding can be by men or
7. Weeding flooded paddies is done
women
by women
8. Higher returns (30-50% increase
8. Lower return on investment
in net income)

31. Challenges faced
• Farmers’ traditional
mindset, addressing
skepticism and
thus, resistance
• The crop was not weeded
with rotary weeders
• The planting calendar affects
rice yields
• Shortage of SRI extension
workers
• A higher incidence of weeds
• Some farmers applying half-
SRI measures
32. Lessons Learnt
• The scientific basis for adoption of SRI has been proven
• Aggressive awareness creation and hands-on training has
resulted in good adoption rates.
• SRI message is now accepted in all 4 schemes
• There are many spin-off innovations, e.g., 3 local people
have fabricated rotary weeders
• Farmer behaviour has changed – most use less water
• Collaborative efforts & cost-sharing helped push the project
success
• Need to engage the private sector - interest by Numerical
Machining Complex to support developing rotary weeders
• Policy support helps – extending SRI to Ahero, West Kano &
Bunyala with NIB support
33. Way Forward
• Train extension workers to support SRI farmers
• Build capacity of farmers to do full SRI
• Develop rotary weeders suited to local conditions
• Raise funds to support farmers & the value chain
• Manage pests and diseases (preventive measures)
• Expand SRI to all rice-growing areas in Kenya and
hopefully, Africa.
• Collaborative research & outreach with other partners
• Achieve 100% adoption of SRI to grow more rice with
less water! 33 4/19/2012
