FIVE THINGS WORTH KNOWING
1. El Niño is now expected to persist into 2027 with exceptional certainty
The World Meteorological Organization says El Niño is firmly established and likely to intensify into a very strong event, with a nearly 100% probability of persisting through February 2027. Its September–November outlook points to above-normal temperatures across most land areas, while a developing positive Indian Ocean Dipole could modify the usual regional effects of El Niño.
For India, the immediate concern is agricultural timing: September rainfall is especially important for summer crops approaching yield-sensitive stages and for replenishing soil moisture before wheat, rapeseed and chickpea planting.
Why it matters: “Strong El Niño” is not itself a local rainfall forecast, but it substantially raises the background risk of heat, drought and rainfall disruption at a point when India’s monsoon is already weak.

2. Severe maternal anaemia is associated with more than three times the risk of stillbirth
A large ICMR-led pooled analysis combines individual-level data from 214,709 pregnancies drawn from eight observational studies and two trials across ten Indian states. Moderate-to-severe anaemia during pregnancy was associated with higher stillbirth risk after adjustment; for severe anaemia below 7 g/dL, the adjusted risk ratio was 3.12 (95% CI 2.46–3.97) compared with no or mild anaemia.
The analysis uses cohort-specific modified Poisson models followed by random-effects meta-analysis, giving it substantially stronger temporal information than a cross-sectional survey association.
Why it matters: India’s anaemia burden is usually discussed in terms of prevalence. These results connect severity during pregnancy to a consequential birth outcome, strengthening the case for identifying and treating severe anaemia rather than relying principally on population-level supplementation coverage.

3. Sri Lanka has adopted its first National Food Safety Policy
Sri Lanka has launched a national framework replacing a largely fragmented approach to food control with a coordinated, risk-based system covering production through consumption. Priorities include surveillance, laboratory capacity, risk assessment, institutional coordination, legislation and communication; implementation is expected to be supported by a revised Food Act currently under development.
The policy was developed by the Ministry of Health’s Food Control Administration Unit with technical support from FAO under an EU-funded programme.
Why it matters: Food safety is simultaneously a public-health and trade-capacity issue. The real test will be whether the new framework improves outbreak surveillance, laboratory reliability and enforcement rather than simply coordinating existing agencies on paper.

4. A national child-labour campaign reports more than 3,800 children rescued
India’s National Commission for Protection of Child Rights says a special campaign conducted between 12 June and 31 August resulted in the rescue of more than 3,800 children from child labour and the registration of more than 575 FIRs. States were also asked to report rehabilitation, restoration, educational mainstreaming and compensation following rescue.
Those numbers require careful interpretation. They measure children identified through enforcement activity, not the prevalence or trend of child labour nationally; more intensive inspections can increase recorded cases even when underlying prevalence is unchanged.
Why it matters: The next useful dataset is not another rescue total but what happens afterwards—school re-entry, compensation, repeat exploitation, prosecutions and household livelihood conditions.

5. Food insecurity is associated with poorer healthy ageing among older Indians—but this is not a current prevalence estimate
A newly published analysis uses 30,250 adults aged 60+ from LASI Wave 1 (2017–18) and constructs a multidimensional Healthy Ageing Index from 28 indicators. Food insecurity was associated with lower healthy-ageing scores after adjustment, while a Blinder–Oaxaca decomposition attributed about 81% of the observed gender gap in the index to measured characteristics, particularly work and marital status.
Importantly, the study is cross-sectional. Neither the association nor the decomposition establishes that food insecurity causes poorer ageing, and the reported 45.3% food-insecurity prevalence describes the 2017–18 sample, not India in 2026.
Why it matters: The paper connects food security with functional, cognitive, psychological and social dimensions of later-life health rather than treating nutrition among older adults purely as dietary intake.

ONE PAPER WORTH READING
Does inequality cause social unrest in rural India?
Couttenier, Laurent-Lucchetti and Vandewalle examine whether changes in within-village economic inequality affect local social unrest. Their unusually granular dataset contains monthly bank-account information from 2,197 Indian villages between January 2015 and May 2017. Savings balances are used as a proxy for income, while riots and protests are identified using ACLED data within 20 kilometres of each village.
The central identification strategy uses rainfall-driven water availability as an instrument for inequality. Positive water shocks disproportionately increase savings among the top two deciles while leaving lower-income savings largely unchanged; instrumented increases in inequality are then associated with greater unrest. A 10% increase in the authors’ inequality measure raises the unconditional monthly probability of unrest by about 6.5%.
This is an unusually clever design, but the causal interpretation depends on a demanding exclusion restriction: water availability must affect unrest through inequality rather than other channels. Bank savings are also an imperfect proxy for household income, particularly where financial behaviour differs systematically across groups.
The paper nevertheless matters because it moves beyond cross-sectional correlations between inequality and conflict and studies distributional change at unusually fine spatial and temporal resolution.

ONE NUMBER
3.12
That is the adjusted risk ratio for stillbirth among pregnant women with severe anaemia (haemoglobin below 7 g/dL) relative to women with no or mild anaemia in the new ICMR-SPIC analysis. The estimate is based on pooled individual-level cohort data rather than a national cross-sectional survey and has a 95% confidence interval of 2.46–3.97.
It should not be read as saying severe anaemia explains three times as many stillbirths nationally. It is an estimated relative risk among women represented in the pooled cohorts after statistical adjustment.

POLICY WATCH
India is trying to strengthen the district institutions through which tribal-development spending actually reaches communities
The Ministry of Tribal Affairs has issued a new roadmap and operational guidelines for Integrated Tribal Development Agencies/Projects (ITDAs/ITDPs) to states. The framework is intended to standardise planning, governance and monitoring and improve coordination between Central and State programmes, including PM-JANMAN and the Dharti Aaba Janjatiya Gram Utkarsh Abhiyan.
The Ministry has also released Adi Darpan, a compendium intended to consolidate programme progress and tribal-development profiles, and is pressing states on utilisation certificates and unspent commitments.
The practical significance lies below the scheme level. Tribal development programmes frequently depend on convergence across health, livelihoods, infrastructure, education and forest-related institutions. Strengthening ITDAs could therefore matter more than introducing another centrally sponsored intervention—but only if the new framework gives local institutions meaningful planning authority and publishes comparable outcome and expenditure data.

EDITORIAL NOTE
“El Niño” is useful information, but it is not an agricultural outcome
There is a tendency to move too quickly from an ENSO forecast to statements about crop failure, inflation or rural distress. The relationship is probabilistic, not mechanical.
WMO’s forecast is unusually strong: El Niño is almost certain to persist through February 2027. But Indian outcomes will also depend on the Indian Ocean Dipole, the spatial and temporal distribution of rainfall, irrigation access, reservoir and soil moisture, crop choice, sowing dates and the particular growth stage at which moisture stress occurs.
This is also a measurement point. All-India seasonal rainfall departure is a poor sufficient statistic for livelihood loss. A better early-warning architecture would combine district-level rainfall anomalies with soil moisture, irrigation coverage, crop calendars, vegetation indices, mandi prices and household dependence on rain-fed agriculture.
The forecast should therefore trigger preparedness—not deterministic claims about what the harvest will be.
