🇰🇳 CLIL: Kenya

Standing at the edge of the Maasai Mara at first light, watching the horizon fill with moving shapes as a million wildebeest begin their crossing, it is almost impossible not to think in “what ifs.” If the migration hadn’t evolved over millions of years, Kenya would look completely different today. If the rains hadn’t failed so badly in 2023, millions of farmers wouldn’t still be recovering now.

These are mixed conditionals — and they are among the most expressive structures in the C1 English toolkit. They connect past events to present realities, and present truths to past consequences. In other words, they answer the question: how did the past shape now? And: how does who we are change what already happened?

In this guide you will learn both types, master the formation rules, practise with real examples drawn from Kenya’s wildlife, environment, and culture, and — crucially — avoid the specific traps that catch Spanish speakers out every time.

What is a mixed conditional?

You already know the second conditional (present hypothetical → present/future result) and the third conditional (past hypothetical → past result). A mixed conditional does exactly what its name suggests: it mixes the time frames of those two patterns in a single sentence.

The result is a sentence where the condition and the result belong to different moments in time. There are two main types, and each has a clear logic.

The two types at a glance

Type A — Past condition, present result: Something that didn’t happen in the past would change how things are right now.

Type B — Present condition, past result: Something that isn’t true now would have changed what happened in the past.

Formation

Type A — Past condition → Present result

Use Type A when you want to describe the present consequences of a past event that didn’t happen. The if-clause sets up the hypothetical past action; the main clause describes its imagined effect on the present.

Clause Form Kenya example
If-clause
(hypothetical past)
If + subject + had + past participle If Kenya hadn’t invested in conservation …
Main clause
(imagined present result)
subject + would / could / might + bare infinitive … it wouldn’t be the world’s leading safari destination now.

Notice: the if-clause uses past perfect (had + past participle), just like a third conditional. The main clause uses would + bare infinitive, just like a second conditional. That crossover is the “mix.”

Type B — Present condition → Past result

Use Type B when you want to describe how a current reality would have changed a past event. The if-clause anchors the hypothetical in the present; the main clause looks back to what would (or wouldn’t) have happened.

Clause Form Kenya example
If-clause
(hypothetical present)
If + subject + past simple / were If Kenya weren’t the world’s leading safari destination …
Main clause
(imagined past result)
subject + would have + past participle … the pandemic shutdown would have been even more devastating economically.

Here the if-clause uses past simple (or were for all persons in formal writing), just like a second conditional. The main clause uses would have + past participle, just like a third conditional.

🌎 Kenya in context: mixed conditionals in the wild

Kenya’s history — of conservation decisions, ecological crises, and remarkable recoveries — is rich territory for mixed conditionals. Every “turning point” moment invites us to ask: what would now look like if then had been different?

The Great Migration

Every year between July and October, approximately 1.5 million wildebeest, along with around 400,000 zebras and hundreds of thousands of gazelles, cross the Mara River in what is widely described as the Eighth Natural Wonder of the World. The spectacle draws visitors from every continent and is the backbone of Kenya’s tourism economy.

If the Great Migration hadn’t evolved over millions of years, Kenya’s tourism economy would look entirely unrecognisable today. (Type A: past condition → present result)
If Kenya weren’t home to the Great Migration, it would not have attracted 2.39 million international visitors in 2024. (Type B: present condition → past result)

Pandemic collapse and remarkable recovery

When global travel shut down in 2020, the Maasai Mara’s annual tourism revenue collapsed from around KES 1.5 billion to just KES 327 million in a single financial year. By FY2024–25, it had rebounded to KES 5.6 billion (approximately USD 43 million) — a recovery that few predicted at the worst moment.

If the Maasai Mara hadn’t built such an internationally trusted brand over decades, the post-pandemic recovery would be far less advanced today. (Type A)
If Kenya weren’t so financially dependent on wildlife tourism, the economic shock of 2020’s travel freeze would have been less severe — though the wildlife would have had a quieter year. (Type B)

Conservation, drought, and the 15 billion tree campaign

The 2024–25 National Wildlife Census revealed significant population declines in buffalo, Grevy’s zebra, hirola, and sable antelope — largely the result of sustained drought, habitat loss, and disease. In response, Kenya has launched an ambitious 15 Billion Tree Planting Campaign aimed at restoring degraded land and reversing decades of deforestation.

If deforestation hadn’t accelerated across Kenya’s highlands over the past half-century, the wildlife census numbers might tell a very different story today. (Type A)
If Kenya weren’t actively investing in its tree-planting campaign, the habitat restoration that began after 2022 would have had far less political momentum behind it. (Type B)

The Maasai, the Mara, and co-managed conservation

The Maasai Mara was first designated a wildlife sanctuary in 1948 and upgraded to a national reserve in 1961. It now covers 1,510 km² and is surrounded by more than 30 community conservancies managed in partnership with the Maasai people — an arrangement that emerged from years of negotiation and trust-building.

If the Maasai community hadn’t agreed to co-manage the conservancies alongside the government, the buffer zones protecting the reserve would be far more difficult to maintain today. (Type A)

⚠️ Common mistakes for Spanish speakers

Spanish has a rich subjunctive tradition, which gives you a head start with hypothetical structures. But mixed conditionals still trip up Spanish-speaking learners in very predictable ways.

1. Using “would” inside the if-clause
❌ If Kenya would have protected its coastal forests, the coral reefs would be in better condition today.
✅ If Kenya had protected its coastal forests, the coral reefs would be in better condition today.
Why it happens: The Spanish pattern si hubiera protegido, estarían… maps cleanly onto English, but learners often add would to the if-clause by analogy with the main clause. English never uses would inside an if-clause — not in any conditional type.
2. Forgetting “have” in the main clause of Type B
❌ If Kenya weren’t so famous for safaris, the pandemic would be much worse for the economy.
✅ If Kenya weren’t so famous for safaris, the pandemic would have been much worse for the economy.
Why it happens: Students register the present-tense feel of the if-clause (weren’t) and then write the main clause as if describing the present too. But the pandemic happened in the past — the main clause must use would have + past participle.
3. Using present simple instead of past perfect (Type A)
❌ If the wildebeest don’t migrate every year, Kenya isn’t a top safari destination now.
✅ If the wildebeest hadn’t been migrating through the Mara for thousands of years, Kenya wouldn’t be a top safari destination now.
Why it happens: This collapses Type A into a first conditional. Mixed conditionals are entirely hypothetical — use the past perfect in the if-clause to signal that you are imagining something different from reality.
4. Applying the wrong type because the time logic is blurred
❌ If Kenya hadn’t had so much wildlife, the pandemic would be even more damaging. (past condition but present result — actually fine as Type A, but the logic doesn’t hold: “more damaging” implies the pandemic is still ongoing, which distorts meaning)
✅ If Kenya weren’t so rich in wildlife, the 2020 pandemic would have been even more economically damaging. (Type B: present reality → past result — cleaner and more precise)
Quick test: Ask yourself — is the condition about something in the past, or something that is true/false now? That gives you the type.
5. “Was” instead of “were” in formal writing
❌ If Kenya was not a member of the African Union, its conservation diplomacy would have developed very differently.
✅ If Kenya were not a member of the African Union, its conservation diplomacy would have developed very differently.
Why it matters: In formal and written C1 English, were is used for all persons (I/he/she/it were) in hypothetical if-clauses — this is the subjunctive mood. In casual spoken English, was is increasingly common, but at C1 written level were is the expected form, and examiners notice the difference.

Example bank: 16 mixed conditionals from Kenya

A = past condition → present result  |  B = present condition → past result

  1. If Kenya hadn’t established the Maasai Mara as a protected reserve in 1961, the open savanna grasslands might no longer exist in their current form. (A)
  2. If the annual wildebeest migration hadn’t captured international imagination, Nairobi’s tourism infrastructure wouldn’t be as developed as it is today. (A)
  3. If the Kenyan government hadn’t invested in anti-poaching programmes over the past two decades, the lion population in the Mara would be in far greater danger right now. (A)
  4. If Wangari Maathai hadn’t founded the Green Belt Movement in 1977, Kenya’s environmental voice on the world stage would almost certainly be less powerful today. (A)
  5. If deforestation hadn’t stripped so much of Kenya’s highlands over decades, the 2023 drought would have caused far less devastation, and many farmers would be in a more secure position now. (A)
  6. If Kenya weren’t the world’s leading safari destination, it would not have attracted approximately 2.39 million international visitors in 2024. (B)
  7. If the Mara River weren’t home to one of the largest hippo populations on the continent, the river-crossing spectacle would have drawn far fewer cameras over the decades. (B)
  8. If Kenya weren’t situated along the Great Rift Valley, its landscape would have appeared entirely different to the first European explorers who arrived in the nineteenth century. (B)
  9. If community conservancies weren’t such a central part of Kenyan wildlife management, the decline in Grevy’s zebra numbers would have gone undetected for much longer. (B)
  10. If Kenya weren’t actively pursuing its 15 Billion Tree Planting Campaign, the habitat restoration efforts that began after 2022 would have had far less political and financial momentum. (B)
  11. If the Maasai Mara hadn’t built such a strong global reputation before 2020, its tourism revenue would still be recovering from the pandemic collapse rather than exceeding pre-COVID levels. (A)
  12. If park entry fees hadn’t been raised in recent years, the Mara’s annual revenue would not have reached KES 5.6 billion by FY2024–25. (A)
  13. If Kenya weren’t a signatory to international wildlife protection conventions, poaching levels would have risen far more sharply during the 1980s ivory crisis. (B)
  14. If the Maasai people hadn’t agreed to co-manage the conservancy buffer zones, the reserve would be considerably harder to protect along its outer edges today. (A)
  15. If the wildebeest migration corridor between the Serengeti and the Mara hadn’t been kept largely free of permanent fencing, the wildebeest population would be a fraction of what it is today. (A)
  16. If Kenya’s climate weren’t becoming increasingly unpredictable, the conservation strategies developed in the 1990s would have proved sufficient for another full generation. (B)

🌃 Quick practice quiz

Test yourself on the five questions below, then reveal the answer key.

  1. Type A or Type B?“If the Maasai Mara weren’t so internationally famous, it would not have recovered from the 2020 tourism collapse so quickly.”
    a) Type A    b) Type B    c) Neither — this is a standard second conditional
  2. Correct the error:“If Kenya would have protected its coastal mangroves earlier, the marine ecosystems would be far healthier now.”
  3. Complete the sentence:“If the rains __________ (not fail) so dramatically in 2023, millions of Kenyan farmers __________ (be) in a stronger position today.”
  4. Which option is correct in formal written English?
    a) If Kenya was not a member of the African Union, its conservation diplomacy would have developed in isolation.
    b) If Kenya were not a member of the African Union, its conservation diplomacy would have developed in isolation.
  5. Write your own: Using a fact from this lesson, write one mixed conditional of either type. Underline the verb form in the if-clause and circle the verb form in the main clause.
▶ Reveal answer key
  1. b) Type B. The if-clause describes a present-tense reality (isn’t so famous), and the main clause refers to a completed past event (would not have recovered). Present condition → past result = Type B.
  2. Corrected: “If Kenya had protected its coastal mangroves earlier, the marine ecosystems would be far healthier now.” — Would must never appear inside the if-clause. Use past perfect (had protected) for the hypothetical past condition.
  3. hadn’t failed … would be. Type A: past perfect (hadn’t failed) in the if-clause; would + bare infinitive (would be) in the main clause for the present result.
  4. b) were. In formal and academic English, the subjunctive were is used for all persons in hypothetical if-clauses. At C1 level in written contexts, this is the expected choice.
  5. Open answer. Example: “If the Maasai community hadn’t co-operated with the national reserve management, the conservation buffer zones would be in far worse shape today.” (Type A)
