Evidence database

Evidence of the effectiveness of anticipation is important for several reasons. Firstly, the selection and design of effective early actions is pivotal for implementation success. Secondly, evidence enables advocates and practitioners to demonstrate the impact of this emerging approach to humanitarian action. Thirdly, sharing and learning from each other’s successes and failures will help the anticipation community maximize its impact. 

This database complements the Early Action Database by collating evidence on the effectiveness of (potential) early actions. Its primary purpose is to help practitioners evaluate and compare early actions based on existing data. As anticipation is a relatively new concept, evidence from anticipatory humanitarian programs may be lacking for many actions. For this reason, to the extent possible, the database also includes evidence from Development, Disaster Risk Reduction, and Humanitarian Response interventions/actions that could be adapted to the anticipatory context (see the implementation context filter). This way, practitioners can still learn from what is known about specific interventions in non-anticipatory contexts.

While the database is primarily meant to inform the selection and design of anticipatory actions, as the evidence specific to anticipation grows, it may also help advocates build arguments for early action, and help Monitoring, Evaluation, Accountability and Learning experts more easily identify and share studies relevant to their work.

Growing this database is a community effort.  If you know of a study/evidence not reflected in the database, please contact  Arielle Tozier de la Poterie.

After you use the database, please submit your feedback here to help us improve the database’s design and utility in the future.

  • Implementation context

    Anticipatory Action

  • What the evidence says

    "1. Anticipatory cash payment has statistically significant impacts on improving households reduced coping strategy index (rCSI) and livelihood coping strategy index (LCSI). Households who received cash payments before the peak of flooding are less likely to employ negative coping strategies in response to floods. However, in terms of the short-term food consumption impacts, we do not see significant differences between pre- and post-shock cash households.

    2. Of the four livelihood diversification indicators considered in the study, we found that anticipatory cash payments have a statistically significant impact on household’s labor re-allocation including migration. We do not find evidence on the impacts of anticipatory cash on crop diversification, mixed crop-live- stock diversification, and non-farm business activities.

    3. Anticipatory cash payments have significant impacts on the number of pre-emptive actions taken by households in anticipation of floods, but no significant impacts on the number of post-shock actions.

    4. Anticipatory cash transfers had positive and statistically significant impacts on productive investments (agricultural assets and productive livestock). Productive investments could enhance a household’s future income generating capacity and reduce their vulnerability to future shocks, thus improving long- term resilience capacity.

    5. Finally, our results do not show significant differences in measures of subjective wellbeing between the pre- and post-cash households. Similarly, our heterogeneity analyses show that the impacts of anticipatory cash on various outcome measures are not sensitive to household wealth status, which may imply that households in the study communities are generally economically poor."

    The research team took a baseline of 1450 households in April and May of 2022, before the flooding season. When pre-determined trigger thresholds were met on July 27th 2022 (e.g., when river water volume exceeded a certain amount and the probability of a flood was high) IRC delivered N195,000 to 725 households across six communities (the treatment group). A control group of 725 received an equal cash payments after the flood hit (November 7th). Endline data was collected from the same households in December 2022.

  • Implementation context

    Anticipatory Action

  • What the evidence says

    91 percent households reported spending the cash on food and/or water. Children in households that received anticipatory cash were 3 percent morel likely to have consumed 3 or more meals in the day before data collection (three months after the intervention). Adult food consumption scores were also higher. Evidence suggests that those that received cash earlier had higher adult food consumption scores. 

    Intervention households experienced less loss of or damage to their assets relative to the control group.

    Intervention households were 8% less likely to lose small livestock and 5% less likely to lose poultry during and after the flooding.

    Beneficiary households scored an average of 12.5 percent higher on Cantril's ladder of life satisfaction (though both treatment and control groups were quite low).

    Intervention households were not more likely to prepare for the flood than control households, but households that received the cash transfer were 12% more likely to evacuate household members and 17% more likely to evacuate their livestock.

    On average, households receiving the cash transfer borrowed $7 less and at lower interest rates than control households in the two months after the onset of flooding.

  • What the evidence says

    Anticipatory cash recipients were better able to evacuate vulnerable household members from flood affected areas (27% vs 11% of non-benficiaries)

    Between 10 and 13 percent lower livestock mortality rates

    21 percent fewer losses of productive assets

    Anticipatory cash recipients experienced 10 percent fewer health issues (fever, cough, skin rashes); There was no statistically significant differences for more severe health impacts, such as diarrhoea, dysentery, and physical injuries (e.g., broken bones).

    12 percent fewer recipients of anticipatory cash recipients reported borrowing money (44% of beneficiaries vs 56% of non-beneficiaries; 95% confidence level); For those that still borrowed money, there was no statisitcal difference in the amount of money borrowed or in interest rates.

    Anticipatory cash recipients reported better well-being overall: on a scale for assessing subjective well-being from 1 (very bad) to 5 (very well), beneficiaries reported an average status of 3.6 vs. 2.3 among the comparison group (statistically significant at the 99% level). No household receiving anticipatory cash reported having to sell household assets vs. 12% of the comparison group (95% confidence). There were no statistically significant differences in the sale of other assets, such as land livestock, productive equipment or personal items.

    No effect on food-based coping strategies or earlier recovery of productive capacity

    WASH, HEALTH, SECURITY, FOOD SECURITY & LIVELIHOODS, EARLY WARNING

  • Implementation context

    Anticipatory Action

  • What the evidence says

    100% of FbA beneficiaries reported that they evacuated to a cyclone shelter, whereas 97% of comparison households declared the same (+3%). Therefore FbA assistance was effective in ensuring that everyone evacuates (whereas without FbA, 3% of households might not have been evacuated).

    Of those who received an early warning, 33% of FbA beneficiaries said they were warned by BDRCS vs. only 13% of the comparison group were warned by BDRCS (+20%); 81% of FbA beneficiaries were warned by CPP1 vs. 92% of the comparison group (-11%); and 46% of FbA beneficiaries vs. 32% of the comparison group were warned by mobile phone (+14%).

    Evacuation of animals was lower among FbA beneficiaries (42%) than in the comparison group (53%) with a difference of -11%. Other variables measuring actions taken by households after the warning were not statistically different between the two groups. Although the provision of shelter space for livestock is included in the EAP, only 30% of FbA beneficiaries said there was a place for their livestock at the shelter vs. 44% of the comparison group (-14%). This was likely due to the fact that BDRCS was not able to select the shelters at which to provide services; therefore in many cases the shelters were far away and difficult to reach, thus livestock shelters could not be built there.
    There was no difference in the number of days that intervention and non-intervention households were unable to work after the cyclone. Both groups reported the inability to work for an average of 40 days as a result of the cyclone. Overall, 29 percent of beneficiaries reported experiencing the death or loss of at least one animal because of the cyclone, compared to 63% of respondents from the comparison group. There were no statistically significant differences between the two groups in terms of loss of “chickens and pigeons,” “cows and calves,”or “sheeps and goats.” However, only 29 percent of the FbA beneficiaries reported losing ducks compared to 46% percent of non-beneficiaries.

    FbA beneficiaries reportedly received a higher level of assistance at the shelters, they had an overall better experience with less problems, and access to more services. The overall shelter experience was rated better by FbA beneficiaries, with an average score of 6.2 (out of 10) vs. 5.3 (out of 10) for the comparison group (+0.9 points). 75% of FbA beneficiaries reported receiving water at the cyclone shelter (serviced with support from BDRCS), vs. only 58% from the comparison group who were at a shelter not supported by BDRCS (+17%). With regard to COVID-19 precautions, 62% of FbA beneficiaries said to have received masks and hand sanitizer at the shelter vs. 33% of comparison households (+29%). 41% of FbA beneficiaries received hygiene items such as soap vs. 29% of comparison households (+12%). 73% of FbA beneficiaries said that light was provided at the shelter vs. 60% of comparison households (+13%).

    There was no statistically significant difference in the food available to the two groups at the shelters.

    FbA beneficiaries reported fewer problems at the cyclone shelters: 29% of FbA beneficiaries said there was a lack of water at the shelter vs. 49% of comparison group households (-20%); A lack of sanitation facilities was experienced by 43% of FbA beneficiaries vs. 61% of the comparison group (-18%); 60% of FbA beneficiaries at shelters supported by BDRCS complained about the lack of space at the shelter (overcrowding) vs. 74% of the comparison group who experienced the same at shelters without BDRCS support (-14%) (Figure 11).

    15% of FbA beneficiaries reported experiencing health problems and physical injuries (such as bruises and fractures) after and because of the cyclone comparted to 27% of non-beneficiary comparison households, a 12 percent reduction (statistically significant at the 90% confidence level). However, no differences between the two groups were observed for other health concerns such as coughing, skin rashes, and diarrhoea, or for mental health and psychological distress.

    Only 4 percent of beneficiary households resorted to destitution sales of house assets (such as cooking stoves, radios, fridges, beds, furniture) to obtain cash to cope with cyclone impacts compared to 58 percent of households in the comparison group (a 54% reduction, statistically signficant to 99%). However, beneficiaries were more likely (24 percent of beneficiaries vs 2 percent of non-beneficiaries) to sell other assets, like jewelry or clothing. 
    There was no statisitcally significant difference between the number of households in each group taking out new loans or the value or interest rate of those loans

    The anticipatory interventions were effective in reducing impacts on agricultural activities. 29 percent of total respondents owned or rented land for agricultural or aquacultural cultivation. Of these, FbA beneficiaries reported losing an average of 52 decimals of cultivated crops/aquaculture compared to average losses of 109 decimals in the comparison group (-57 decimals). Cyclone-induced losses to aquaculture occur when storm surges increase the salinity of water above shrimp’s tolerance. Given that average Bangladeshi farmer cultivates only 74 decimals (0.74 acres or 0.3ha), the losses of 109 decimals reported by the highly vulnerable comparison group are likely overreported (Asian NGO Coalition, 2012). Finally 14 percent of FbA beneficiaries reported having to replant their crops as a consequence of the cyclone, eight percent more than respondents in the comparison group (6%).

    The EAP for Amphan Cyclone was activated on 18th May 2020.  BDRCS reached 192 shelters in 64 Unions under 10 Districts with Early Actions before the landfall. Around 36,500 beneficiaries were reached and provided dry food, safe drinking water, masks, hand sanitizer, and soap to cope with hygiene security due to Covid-19 pandemic. Shelters were disinfected before the evacuation. Livestock were also evacuated to shelters.

    The statisically significant benefits of the FbA intervention were:

    1. Helping households evacuate household members (RQ1);
    2. Reducing the overall impacts of the cyclone on the health conditions of household members (RQ2);
    3. Reducing the impacts of the cyclone on livestock and agricultural activities (RQ5);
    4. Improving the overall shelter experience of the household, with less problems experienced and more services received (RQ7); and 
    5. Reducing the selling of household assets as a coping strategy for financial and economic constraints after the cyclone event (RQ8).

    No evidence was found for the following impacts:

    1. Improving the general psychological conditions after the cyclone event (RQ3);
    2. Reducing the impacts of the cyclone on household assets (RQ4);
    3. Reducing the borrowing of money and the selling of household assets as coping strategies after the cyclone event (RQ6); and
    4. Improving the resilience of the household in terms of resuming working activities (RQ9).

  • What the evidence says

    The FbF intervention appears to have been effective in enabling vulnerable households to evacuate the flood area where needed: 27% of FbF beneficiaries reported that they evacuated adults after receiving an early warning, vs 11% (+16%) of respondents among the comparison group.

    51% of FbF beneficiaries indicated that some of their working equipment (such as tools, fishing equipment, pumps, etc.) was damaged to some degree or lost vs. 72% of comparison households (-21%). Differences for other kinds of assets were not statistically significant. 

    Fewer FbF beneficiaries reported experiencing health problems (such as coughing, skin rash) because of the flood (73% of FbF cash recipient’s vs 84% of comparison households, an 11% reduction).

    There was no difference in the level of stress experienced by beneficiary and non-beneficiary households.

    The FbF cash transfer helped beneficiaries reduce livestock losses. Out of 42% of households who said they owned or look after cows or calves, FbF beneficiaries indicated losing 9% vs. the comparison group, which reported losing 22% of them (-13%). The FbF beneficiary group reported that 50% of their chickens and pigeons died because of the flood event. Comparison households reported losing 60% of their chickens and pigeons (-10%). Differences in mortality for other animals (sheep, goats, and ducks) and for agricultural crops  were not statistically significant.

    97% of FbF beneficiaries reported that they, or an adult member of their household, was unable to work for a period of time because of the flood, compared to 86% of comparison households without FbF assistance at the shelter (+11%). There was no difference in the average number of days people were unable to work after the event between the two groups (approximately 46 days for each group). This result is unexpected, but it might depend on external factors not linked to the intervention itself. There are no other significant differences on the averages of the two groups related to other aspects of damages, such as other health problems, damages to vehicles or to houses.

     44% of FbF beneficiaries said they had to borrow money to cope with the impacts of the flood vs. 56% of the comparison group (-12%). However, for those that did borrow, there was no statistically significant difference in the quantity of money borrowed or the interest rate. 

    None of the FbF beneficiaries had to sell household assets (such as beds, furniture, cooking stoves, kitchen items, etc.), whereas 12% of the comparison group did so to cope with difficult economic conditions after the flood (-12%). There were not statistically significant differences in the two groups when it came to selling other assets (e.g. land properties, livestock, working equipment or personal items).

    The intervention had no statistically significant impact on food-based coping strategies.

    The EAP for floods was activated on 25 June 2020. BDRCS reached 3,789 households in 10 Unions under 3 districts with an unconditional multi-purpose cash grant of 4,500 Bangladeshi Taka (BDT) (about 53$). A vulnerability score for each household was computed using five criteria: quality of housing structure; level of inundation during previous floods; number of dependents in the family (children, elderly, or disabled); family structure (female-headed, widowed, divorced etc.); livelihood strategies.

    90% of beneficiaries reported spending the cash grants on food, 34% on livestock, 29% on health and 24% on evacuation. 

    Discussions are ongoing about how much cash is enough to contribute to the desired outcomes overall.

  • What the evidence says

    Households in Bangladesh receiving cash before the flood were more likely to buy food and reinforce their homes. Only seven percent of recipients took no early actions before the flood, as compared to 20 percent in the comparison group. 
    Recipients of cash in Bangladesh spent the money on the following:
    92% spent a portion of their cash grant on food;
    65% used FbF money to pay for health expenses;
    45% bought non-food items (NFIs) such as soap, jerry- cans, buckets or clothing;
    35% spent some FbF cash towards evacuation costs, including boat transport and hiring labor to help move household items or livestock;
    90% reported spending most of the money before the flood peak.

    86 percent of recipient households in Bangladesh evacuated their homes before the flood, as compared to 76 percent in non-intervention communities.

    This intervention sought to prevent destitution sales of assets. According to survey results (data collected after second flood peak), the majority of Bangladeshi households in intervention and non-intervention groups sold their assets. However, qualitative focus groups (held before a second flood peak) indicated that intervention communities were less likely to have sold assets such as cookstoves and livestock. 

    Survey results from Bangladesh indicate a positive impact on the availability of nutritious food during the flood period. Households receiving assistance were less likely to have to eat only rice  (71 percent as comparted to 95 percent) and for a fewer number of days than non-beneficiaries. 

    Households receiving anticipatory assistance were statistically less likely to accrue new debts during and immediately after the flood. 42 percent of Bangladeshi households receiving anticipatory cash took out new loans during or after the flood, as compared to 60 percent of non-recipients. The total value of the loans were also significantly larger among non-beneficiary households. Households who did not receive anticipatory cash were more likely to borrow from banks or moneylenders at high interest rates. 

    Households who received anticipatory cash in Bangladesh were statistically less likely to be miserable, unhappy, anxious or depressed in the seven days before the survey. This finding was based on a rudimentary scale, and should therefore not be over interpreted, but was corroborated by focus group data in which non-beneficiaries were more likely to express anxiety. 

    There was no statistically significant difference in illness between intervention and comparison groups in Bangladesh following the flood.

  • What the evidence says

    There were no statistically significant effects of receiving anticipatory AHA cash transfers on post-treatment herd size, household income, investments in adaptive strategies, and consumption when considering the average effects across the full sample of pastoralists, which included both households considered subsistence producers (herds < 300 sheep forage units) and households considered commercially oriented pastoralists by Mongolian standards (> 300 sheep forage units). This is true when controlling for the intensity of the disaster as well. However, "results indicate that the AHA cash transfers helped pastoralists with smaller pre-treatment herd sizes to increase the number of goats and sheep owned after the disaster, increase the likelihood that households generate income from the sale of animals, and to purchase animal fodder compared to recipient households with larger pre-treatment herd size. All interaction effects are statistically significant, at least at the 10% level. Although the heterogeneity analysis is constrained by a limited sample size, the combined evidence indicates that cash transfers have positive and economically large effects for the group of subsistence-oriented households" (p. 25). A rudimentary calculation of the return on investment of AA for less wealthy pastoralist households concludes that for every USD invested, households increased the value of their herds by 3.5 USD. This includes money distributed to households who did not experience the dzud with the intensity projected by the forecast--i.e. those assisted in vain.

    Anticipatory Action

  • What the evidence says

    This study compared the impact of anticipatory actions taken separately by Mongolia Red Cross Society (MRCS) and FAO to MRCS emergency response and a control group who received no aid. 

    The study calculated the following benefit-cost ratios for these three interventions:
    1.05 for MRCS
    1.26 for FAO 
    1.71 for DREF. 
    This means that for every US dollar invested by in anticiaption or response by MRCS and FAO beneficiary households received a benefit of US$ 1.05, US$ 1.26, and US$ 1.71. The survey did not collect any data on the amount of milk produced, therefore the current benefit estimates could not include income from milk. These estimates were stable in sensitivity analyses (best and worst case scenario simulation) with an exception for MRCS.

    The study found that both anticiaptory programs and the emergency response were effective in preventing vulnerable herder households from making destituion sales of valuable assets. Beneficiaries of MRCS anticipatory action were 17% less likely to engage in this behavior and FAO beneficiaries were 43% less likely (than the control group). Beneficiaries of MRCS response were 20% less likely than the control group. Those receiving anticipatory aid from MRCS sold 8% more sheep, suggesting either increased destitution sales or proactive sales before expected price decreases. 

    MRCS beneficiaries were also more likely to forego consumption. 

    Beneficiary groups borrowed at the same rate as the control groups, but those receiving anticipatory cash from MRCS borrowed an average of $USD 132 less than others (nearly 60% of the value of the cash transfer).

    Beneficiaries of MRCS response aid had food consumption scores 3.5 point higher than the control group, while FAO beneficiares of early action were 3 points below. 

    FAO anticipatory actions reduced the number of animals in poor health by nearly 7%, whereas MRCS' early actions increased the number of animals with deteriorating health by 7%. The analysis found no difference in the mortality of sheep compared to the control group. MRCS early actions increased offspring survival by 5%, but no impact was found for FAO early actions. 

    Both groups of anticipatory action beneficiaries produced less cashmere than the control group (4kg less on average for MRCS and 8Kg less on average for FAO). MRCS beneficiaries reported obtaining prices up to 2% higher for their cashmere than other groups.

    This study compared the impact of anticipatory actions taken separately by Mongolia Red Cross Society (MRCS) and FAO to MRCS emergency response and a control group who received no aid. The Mongolian Red Cross Society (MRCS) and the Food and Agriculture Organization (FAO) triggered their FbF/AA mechanisms in January 2020 to anticipate and mitigate dzud impacts that year. Both agencies delivered unconditional cash grants (approx $84 from MRCS and $96 from FAO) and animal care kits to 1,450 of the most vulnerable herders across a total of 12 provinces and 83 soums. There were differences between the animal care kits distributed by each organization. See the full report for details. In addition, MRCS mounted an emergency response in March 2020, providing an additional l 1,750 households with the same bundle of cash and animal cares kits as distributed before the event. 
    The study used the following sample sizes:

    • 202 households (of 1000 total) for MRCS intervention site; 
    • 150 households (of 450 total) for the FAO intervention site; 
    • 201 households (of 1750 total) for the DREF intervention site.  
    • 201 control households, which were similarly vulnerable and dzud-affected households but did not receive any FbF assistance. 

    MRCS beneficiaries received approximately USD 84 before (January) or after (mid-March) the event. FAO households received USD 96 before the event (early March)

  • What the evidence says

    One trial found that indoor residual spraying appeared to be more protective than bed nets in areas where malaria is endemic, occurring over many months/years. In areas where malaria transmission is unstable (less frequent, and therefore the population is less likely to have developed immunity), insecticide-treated nets appear to be more protective than indoor residual spraying.

  • What the evidence says

    Space spraying refers to the outdoor application of chemicals to kills mosquitoes. Only the adult mosquito population is targeted with space spraying, not the juvenile stages. This review evaluated the space spraying for malaria prevention at a population level (rather than a household level as is done with indoor residual spraying) and impacts on the vector population. It compared space spraying on its own or in combination with other control measures to doing nothing. The evidence from the four studies identified is low quality and inconclusive. The authors note that space spraying is expensive to implement on a routine basis as it requires specific equipment and experienced staff.

No further trials of ITNs in pregnancy are required in sub-Saharan Africa. Further evaluation of the potential impact of ITNs is required in areas with less intense and Plasmodium vivax transmission in Asia and Latin America"(p. 2).

    For-for-work beneficiaries had higher food consumption and food security scores, especially  those with greater per-capita expenditures. They were also less likely to invest in livestock holdings and perceived their risk of famine to be lower. Food distributions had the greatest impact on poorer households, increasing food consumption but also increasing perceived risk of famine.

    The result shows that FCS of beneficiaries who received cash assistance at the anticipatory response phase is higher than compared to the beneficiaries assisted at the post-shock phase. On average, households receiving cash before the shock had higher food security Food Consumption Score (51.9) than post-shock beneficiaries (48.6). This finding was found to be statistically significant at p-value 0.009.

    Note that both groups had acceptable Food consumption scores: Thresholds -> Poor Food Consumption (0-21), Borderline Food Consumption (greater than 21-35) and Acceptable Food Consumption (35 Above).

    This study seeks to compare the impact of anticipatory cash transfers and post-impact cash distributions. Results are from a survey of recipients of AA and response aid, 14 focus group discussions, and KII with relevant officials at the municipalities and/ or local government representatives of all seven municipalities visited. Audio records and notes from these qualitative discussions were transcribed, translated, coded, and segregated by themes to support the data analysis phase. Survey data collection was done in two different stages reaching out to a total of 710 surveys covering WFP’s anticipatory response (n=379) and post-shock (n=331) cash distribution. Likewise, the PDM presents findings from 277 UNFPA beneficiaries and nine out of 250 UN Women beneficiaries.

    Sampling for PDM was done randomly at a single stage, whereby the total sample size consists of beneficiaries of all three agencies -- WFP, UNFPA and UN Women. Therefore, as the sample calculation was not done to specifically represent the actions of all three agencies, the agency-specific quantitative findings presented in this report are only indicative.
