Data from the USDA published in October showing just how significant the drop in this year's maize production is compared to the five year average.

Have you ever seen El Niño and La Niña stripes like this?

They show subsurface ocean temperature anomalies in late October from 1993 (left) to 2026 (right), with the western Pacific on the top of the stripe and eastern Pacific on the bottom.

Each year tells a different story.

Another big blob 2,000 km out gets blue-dotted. So are we looking at another cyclone that will hang around for many days and deny rain to big parts of East Africa?

@musembidigital Shrink them up with garlic by marshing garlic (4-6 cloves) + 250mL of water• Macerate 1 night, sieve, dilute with 2.5L water. Unaweza ongezea Aloe vera. Zitakauka. Also look at your spray coverage.

[Samuel Njogo @SNjogoh]

My wish.

It appears to be sitting out there and slowly dissipating. Does that mean we'll get some seasonally normal weather fairly soon?

Kenyans should be paying close attention to what’s happening to the Ugandan shilling.

It has fallen more than 14% against the dollar since June, forcing the Bank of Uganda into an emergency rate hike to 12%.

Here’s why it matters to us:

a) Uganda is among Kenya’s largest export markets.

It bought KES 162.4bn of Kenyan goods in 2025, including medicines, cement, metal products, soap and palm oil.

A weaker shilling makes all of that more expensive for Ugandan buyers.

b) Our listed companies are exposed.

KCB, Equity, Stanbic, I&M and DTB all have Ugandan subsidiaries, and EABL owns Uganda Breweries.

Every Ugandan shilling they earn is now worth less when converted into Kenyan shillings.

c) Regional pressure tends to spread.

Uganda’s problems came from the same oil shock and strong dollar that Kenya faces. Our shilling has held around 129.8,

When one of your biggest customer’s currency falls 14%, it eventually shows up in your exports, your companies’ earnings.

Afternoon rains have started in some parts of the Rift, per the prediction in the quoted post

[Samuel Njogo @SNjogoh]

Thank you. Insightful.

The raging tropical depression in the Western Indian Ocean, South of the Equator, has morphed into a moderate tropical storm "TWO". It's wind gusts were spinning at a top speed of 64 Kph as of today morning.
The interesting thing is that it appears to be spinning westward towards the Kenyan coast, but it won't make a landfall because of weak coriolis force near the Equator and strong wind shear off the #Kenyan Coast.
At the moment there seems to be model uncertainty regarding where the remnant moisture of the tropical storm will be transported by the South Easterlies and the impact on precipitation enhancement in the #Kenyan interior in the coming days seems to be negligible.

It's a bit disheartening that most of these former forest zones are now fast becoming Plots (50m*100M), soon to be residential zones. More and more Concrete and Mabati, in the name of maendeleo.

Another group of forests🌲 separated by human activity 🏗 in Laikipia County.

Loriak, Rumuruti and Nyahururu (Marmanet) forests was one massive woodland 🌳🌳.

These forests were once used as a wildlife migration corridor for elephants 🐘.

[Samuel Njogo @SNjogoh]

Meru Exports, and the Milk, Coffee and Miraa, in that order of excellence. What else can we add?

[Mwenda @MwendaKev]

Eldoret looks like the furthest west you ca get a direct Matatu from Meru.

[Great Ngugi @GreatNgugi]

Another group of forests🌳 divided by human activity in the Rift Valley.

We really need to take care of our remaining few natural forests🌳.

[Samuel Njogo @SNjogoh]

Good work. Will appreciate one for Marmanet, Lariak and Rumuruti forests.

[Great Ngugi @GreatNgugi]

Kakamega and Nandi Forest 🌳.

Kakamega Forest🌲 and the Nandi forests 🌲 formed one large, continuous forest block in the past.

Human activity🏗, expanding agriculture🏕, gold mining🟡, and road construction🛣 broke the continuous canopy into separate fragments.

As the much-awaited OND rainy season draws nearer, medium and short range forecasts are progressively aligning with the long range forecasts we started sharing back in May.
An expansive low pressure zone of deep atmospheric convection, thunderstorms & open sea precipitation has been developing in the Central & Western Indian Ocean over the last three weeks. This is a pointer to a developing +ve IOD coupled with a strong El Nino and favorable conditions setting up for an early onset of significant rains across Eastern Africa in the coming weeks.
All global models are in agreement that this convective belt will expand exponentially this month and propagate Westward towards the Horn of Africa.
Any time from from 10th to mid- Sept Southern Somalia, and the #Kenyan Coastal strip may receive significant pre-seasonal rains from this slow-moving low pressure system. Some locations deep in the Indian Ocean may receive as much as 300mm-500mm in the next few days.
Per some individual North American models, onset of seasonal rains starts in Somalia, Mandera, Wajir & Marsabit in the 1st week of Oct. Some erratic showers may fall in the Rift, Western & Nyanza later this month. The rest of KE is likely to see onset of the OND rains from Mid-October with increased intensity from late Oct onwards.

This sits well with me to some extent. However, we must ask who is responsible for designing fertilizer innovations. Is it solely the responsibility of private sector such as MEA, or shouldnt the government have a stake in this @kalromkulima?

[Sir. Mwangala @jomo_felix]

@DonaldBKipkorir MEA sat back and relaxed, no innovation. When farmers started having productivity issues, MEA never interrogated to inform their next lines of product

[Mwenda @MwendaKev]

Wildfires are a frequent issue in Mt. Kenya's Northern Moorlands. This is in the vicinity of the airstrip and the drone facility that was being established at the Kithoka Beat. Some of the projects this government has undertaken are vital. They are at times poorly communicated.

Kenya🇰🇪: Stop Measuring Development in Concrete - Murang'a Governor Irungu Kangata @HonKangata

There is a serious intellectual problem with defining "development' as what can be photographed, depreciated and entered in an asset register, while treating it as recurrent consumption.

The Parliamentary Budget Office (PBO) performs an important oversight role, but its framework risks teaching counties the wrong lesson: build more concrete, spend less on people, and rank better. That would be an unfortunate triumph of accounting over economics.

A road is an asset, but it wears out. A hospital needs maintenance. A vehicle depreciates. Even a new school begins ageing when children enter it. Education behaves differently. A child who learns to read does not become less literate with time. A nurse car become more valuable with experience.

A teacher who masters mathematics can teach successive generations. Engineers, doctors, entrepreneurs and artisans accumulate knowledge, judgement and networks. Human capital compounds. There is an economic irony here: almost everything government calls "capital" depreciates, while its most important capital can appreciate.

A newly recruited doctor cannot economically be equated with one who has 20 years' experience. The latter has accumulated knowledge and institutional memory. Treating the first doctor's training as recurrent while celebrating the hospital in which both work is like celebrating the chicken coop while forgetting the chicken.
