This week Edwin Ndeke @edwinoblak will share his series on recent flooding in Kenya:
Edwin writes: In March all through to May Kenya saw some of its most catastrophic weather for years. Torrential rains caused devastating floods, at least 228 people died, thousands were displaced and nearly 2,000 schools were affected.
Poorer communities were disproportionately affected. Mathare , with roughly 70,000 residents, is just one part of the densely populated “informal settlement” in Nairobi, and people are still reeling from the impact of the flood.
Unplanned or illegal housing developments that obstruct the flow of water, settlements on riverbanks, and poor drainage systems worsened flood impacts
Because About 70% of Nairobi’s residents live in informal settlements, which occupy about 5% of the city’s land. Congested living conditions push the poorest residents to the margins of the settlement, where they are most vulnerable.
These photos paint a picture of how important it his to fight climate change & effects it has to humans.

Public-sector decarbonisation across the built environment is entering a mature phase as projects move from demonstration to delivery. In the UK, over 100 schools have installed government‑funded solar systems projected to save £220m over their lifetime. Transport for London has commissioned SSE Solar Solutions to supply renewable generation covering 1.16TWh of annual electricity use. The shift towards on‑site energy generation and long‑term power purchase agreements reflects a structural realignment in sustainable construction, reducing the carbon footprint of construction and improving energy security as volatility persists across the grid.
Policy direction in sustainability remains uneven. The EU’s decision to ease CSRD reporting may relieve short‑term administrative pressure but threatens the consistency of data needed for Whole Life Carbon Assessment and lifecycle assessment benchmarks. Meanwhile, the planned US withdrawal from the UN climate framework risks undermining global alignment on embodied carbon standards, sustainable material specification and green procurement. Forward‑looking developers are maintaining high environmental sustainability in construction standards based on investor and occupier expectations rather than regulatory minimums.
Accelerating climate risks are reshaping design practice. Rising sea levels and the UK’s shift between extreme rainfall and heatwaves are forcing urgent reassessment of sustainable building design, drainage strategies and site selection. Low carbon design decisions must now include elevation, adaptation and, where required, managed retreat. Retrofitting to mitigate overheating, damp and drainage deficiencies has become essential across both new and existing low carbon buildings. The emphasis on Life Cycle Cost, building lifecycle performance and end‑of‑life reuse in construction is increasing as part of modern sustainable building practices.
Market evidence confirms the transformation. RICS data points to ESG performance driving asset valuation, particularly in net zero carbon buildings and carbon neutral construction portfolios. Predictive digital tools and AI‑driven maintenance are improving operational carbon outcomes, while circular economy in construction models are scaling through city partnerships focused on affordable housing retrofits. The integration of eco-design for buildings, circular construction strategies and green building materials demonstrates progress toward net zero whole life carbon delivery.
The transition from aspiration to implementation signals a decisive phase for sustainable construction. Achievement of net zero carbon targets now depends on applying life cycle thinking in construction, verifying Whole Life Carbon in materials through environmental product declarations (EPDs) and adopting resource efficiency in construction as a financial as well as environmental imperative. Net zero carbon buildings will define the credibility of decarbonising the built environment in the decade ahead.
