Sustainable management of sedimentation risks in coastal rivers in Southwest Bangladesh: Findings from REACH Khulna Observatory by Uddin, S, Rahman, R, Salehin, M

“…While both sediment movement and concentration are much higher in monsoon season, sedimentation risk appears to be greater in the dry season, reflected in less sediment during ebb tide compared to that during flood tide, owing to less sediment resuspension and sediment movement downstream during ebb tide. …”

Identifying water quality risks and modelling intervention strategies (REACH Policy brief) by Whitehead, P, Hossain, MA

“…Dissolved Oxygen is close to zero in the dry season, there is very high organic pollution loading, as well as high ammonia and large numbers of pathogens in the water. …”

Bringing COVID-19 home for Christmas: a need for enhanced testing in healthcare institutions after the holidays by Smith, DRM, Duval, A, Zahar, JR, Opatowski, L, Temime, L

“…Festive gatherings this 2020 holiday season threaten to cause a surge in new cases of novel coronavirus disease 2019 (COVID-19). …”

Investing in professionalized maintenance to increase social and economic returns from drinking water infrastructure in rural Kenya by Foster, T, Hope, R, Koehler, J, Katuva, J, Thomson, P, Gladstone, N

“…Key findings:<br> -When rural water infrastructure is not professionally maintained, household spending on alternative water sources due to breakdowns in supply can be as much as the initial capital costs of the infrastructure<br> -Professionalized maintenance can reduce repair times to less than two days for both piped systems (otherwise, 46–67 days) and handpumps (otherwise, 43 days)<br> -Drought events increase socio-economic hardship, particularly for handpump users with only a few days of water storage<br> -For handpump users, the cost of alternative sources in the dry season increases by up to USD 0.38 per day, equivalent to 6–14% of daily household expenditure<br> -Women bear the vast majority of time costs of collecting water from alternative sources<br> -Governments and donors can pay three times more per litre of water from emergency water trucking compared to the cost of water provided by a functioning kiosk…”

Policy and practice recommendations on flood risk management in the Awash basin by Taye, MT, Haile, AT, Dessalegn, M, Likimyelesh, N, Bekele, TW, Nicol, A, Dyer, E, Tekleab, S

“…In the Awash basin flooding is a frequent occurrence during the main rainy season in July and August. The changing climate patterns are intensifying extreme rainfall conditions and causing floods in unexpected locations and seasons. …”

“…However, there is insufficient investigation of measured fine particulate matter (PM_2.5) exposure levels, variability, seasonality, and inter-spatial dynamics associated with these behaviours.…”

Sea ice and oxygen by Hambler, C

“…</p> <p><strong>6)</strong> These results are consistent with a hypothesised major influence of Arctic plankton in the seasonality of 'global' oxygen levels. </p> <p><strong>7)</strong> Air temperature near the Poles is very closely synchronized with the seasonal rate of change of oxygen at high latitudes. …”

REACH Story of Change: Turkana Jet research unlocks new understanding of East African droughts by REACH

“…Understanding climate processes is a crucial task for climate scientists looking to improve seasonal forecasts in the Horn of Africa, a region affected by severe droughts. …”

Sustaining safely managed drinking water services in rural schools in Chandpur District, Bangladesh (REACH Discussion brief) by REACH

“…</p> <p>This pilot study in Chandpur District explores the benefits of new, automated data loggers, which attach to the handle of a handpump and report data, estimating daily and hourly water usage and changes in performance, such as seasonal demand or downtime. The latter may be due to no usage (holidays, alternatives) or failure events. …”

Monitoring sick leave data for early detection of influenza outbreaks by Duchemin, T, Bastard, J, Ante-Testard, PA, Assab, R, Daouda, OS, Duval, A, Garsi, J-P, Lounissi, R, Nekkab, N, Neynaud, H, Smith, DRM, Dab, W, Jean, K, Temime, L, Hocine, MN

“…We used linear regression to estimate the weekly number of new sick leave spells from 2010 to 2017 in 12 French regions, adjusting for trend, seasonality and worker leaves. Outbreaks were detected using a 95%-prediction interval. …”
