Abstract
The Farmer Support Activity in Ghana seeks to reinforce resilience, preserve agricultural productivity, and enhance the awareness and capacity of smallholder farmers (SHFs) regarding good agronomic practices. The WFP Ghana Office implements a cash transfer programme to achieve these goals. Transfers are complemented by financial and agricultural sensitization activities.

Transfers are worth a total of approx. 315 USD across installments and will reach around 17,000 SHFs in 163 communities across 17 districts in four regions of Ghana (Northern, North East, Upper East, and Upper West). The programme will be implemented from June to August 2023 during the planting season.

Given that the size and frequency of transfers can influence decision-making patterns (including investment decisions), this impact evaluation will compare the effects of (a) receiving a lump-sum transfer versus (b) receiving three monthly payments on farmers’ spending behavior during the planting season, which can ultimately affect their resilience and productivity. The total transfer size is held constant.

Interventions

Intervention(s)
The Farmer Support Activity in Ghana seeks to reinforce resilience, preserve agricultural productivity, and enhance the awareness and capacity of smallholder farmers (SHFs) regarding good agronomic practices. The WFP Ghana Office implements a cash transfer programme to achieve these goals. Transfers are complemented by financial and agricultural sensitization activities.

Transfers are worth a total of approx. 315 USD across installments and will reach around 17,000 SHFs in 163 communities across 17 districts in four regions of Ghana (Northern, North East, Upper East, and Upper West). The programme will be implemented from June to August 2023 during the planting season.
Intervention (Hidden)
The Farmer Support Activity project is scheduled to be implemented during the 2023 planting season in 17 districts in the relatively more food-insecure Northern Ghana. The project entails two types of interventions:
1. cash transfers using mobile money for a total amount of USD 315 per household; and
2. agricultural and financial sensitization activities.

The objectives of the project are to preserve and improve agricultural productivity and prevent farming households from resorting to negative coping strategies. The total amount of USD 315 may be subject to small changes as the budget for the project is finalized.

There are two levels of targeting:
1. geographic; and
2. community targeting.
Regarding the geographic targeting, the main eligibility criteria are (a) the prevalence of food insecurity, (b) access to livelihood opportunities (particularly farming), (c) the existence of complementary livelihood interventions, and (d) capture under USAID’s Feed the Future Zone of Inference in Ghana. Then, smallholder farmers with access to arable land are identified at the community level while prioritizing the inclusion of vulnerable people such as the elderly, people with disabilities, female-headed households, youths, and large households.

Overall, the intervention targets smallholder farmers (landholdings of up to 10 hectares), approximately 17,000 in 17 districts across four regions, i.e., Upper West, Upper East, North East, and Northern Ghana.

The standard approach consists of making three equally sized monthly transfers of 105 USD each in June, July, and August. In parallel, sensitization campaigns will also take place. Then, in a randomly selected half of the targeted locations, the Country Office will switch from the standard procedure to an alternate lump-sum approach, whereby most of the cash support is provided at the time of the first transfer: 285 USD, followed by two small, equally sized transfers of 15 USD each in July and August.

Support is in the form of mobile money.

Primary Outcomes (explanation)
The Food Consumption Score (FCS, collected during all rounds) is comprised of the number of days in the past week when the household consumed major food categories (e.g., maize, tubers, eggs, vegetables, etc). The final score is the sum of these counts.

The Food Insecurity Experience Scale (FIES, collected during all rounds) is based on a module that asks respondents eight questions capturing a range of food insecurity severity, with yes/no responses over the past 30 days (e.g., "In the past 30 days, was there a time when you or others in your household worried about not having enough food to eat because of a lack of money or other resources?"). The index is then the sum of these values across the eight questions.

Consumption expenditure (not collected during round 1). For discrete items under major consumption categories (food, clothes, hygiene, transport, etc.), we ask the total amount the household has spent on each item over the past week, month, or year depending on the item. We then aggregate these amounts together for the household's total consumption.

The Livelihood Coping Strategies Index (lCSI, not collected during round 1) is based on a module containing 10 questions about a pre-selected set of coping strategies. These strategies were selected to include 4 stress strategies, 3 crisis strategies, and 3 emergency strategies. The classification of these strategies is done according to WFP general guidelines.

The Reduced Coping Strategies Index (rCSI, collected during all rounds) is an indicator used to proxy hardship by measuring the frequency and severity of households' food consumption behaviors when faced with food shortages. According to WFP guidelines, we rely on the five consumption-based strategies that are mandatory to construct the rCSI.

Psychosocial wellbeing
PHQ4 (collected during all rounds) entails 4 standard questions to gauge signs of anxiety and/or depression. Answer options are on a Likert scale with higher values indicating anxiety or depression. The answers are added, and the total score is used to determine whether a person shows signs of either anxiety or depression.
The Cantril Self-Anchoring Striving Scale (not collected during round 1) instructs households to imagine a ladder with steps numbered from 0 (bottom) to 10 (top). The top of the ladder represents the best possible life for the respondent, while the bottom of the ladder represents the worst possible life for them. Respondents are asked to think about where on the ladder they feel they are now. Then, we also ask respondents where they feel they were 2 years ago and where they think they will be in 2 years from now.

Subjective resilience (SERS, not collected during round 1). This index is an equally weighted average of each of the resilience capacity questions standardized to range between 0 (not at all resilient) and 1 (fully resilient) (Jones and d'Errico, 2019).

Agriculture information (not collected during round 1). We collect information on farm assets (ownership, stock, and value) and investments in agricultural activities, farming, livestock, or fishing. Then, we collect information on yields and profits from either activity: crop farming, livestock rearing, or fishing. For livestock, we will compute the Tropical Livestock Unit (TLU) while also collecting information on the numbers of each type of livestock, consumption, and sale of livestock.

Household assets (not collected during round 1). Besides farm assets, we also collect information on the ownership of basic household assets such as tables, chairs, beds, mattresses, radios, TVs, bikes, bicycles, cell phones, and mosquito nets. Then, we inquire about the stock and value of all the items owned by the household. We will collect this information across several rounds, and we will ask households to confirm the previously entered stock of assets.

Risk and time preferences (not collected during round 1). To gauge risk preferences, we will use a hypothetical scenario and ask respondents to choose between a given amount of money that they could receive immediately or the chance of getting an even higher amount of money if the flip of a coin is favorable. At the same time, if the flip of the coin is not favorable, then they would receive nothing. We vary the gap between the certain (immediate receipt) and uncertain (reliant on a coin flip) amounts of money to gauge how risk-averse a person is. Then, to gauge time preferences, we are using yet another hypothetical scenario. This time, we ask respondents to pick between a given amount of money that they could receive immediately or wait till the next month and get a higher amount. Similarly, we vary the gap between today's and next month's amount of money to hypothetically gauge how impatient a person is in regard to receiving an amount of money. That is, how much of a payment a person would require to wait and receive money at a later time.

Intra-household gender dynamics (not collected during round 1)
We ask the female respondent questions related to her agency, voicing women's opinions as well as the existing gender norms in the community.

Investment and saving behaviors, and spending patterns (not collected during round 1).
We ask about the household's allocation of a hypothetical transfer of 1,200 cedis (approx. 100 USD) to gauge spending behaviors. We also ask about savings, loans, credit, and the transfers households receive or give. Then, we compute a standardized costly borrowing index to combine information on (a) how much was borrowed in the last three months and (b) the highest interest rate charged per month (Pople et al., 2021).

Other programme-specific indicators (not collected during round 1)
Time spent in wage employment and the associated wage, engagement in business activities, and the resulting profits, as well as the previous day's time allocation to some main types of activities (agriculture, domestic, non-ag, and leisure) by the household head and the opposite-sex main decision-maker.

Experimental Design

Experimental Design
The impact evaluation will use a cluster randomized control trial to compare two groups of villages: lump-sum vs. equal installments. Thus, a lean impact evaluation will be employed, which does not require a “pure control” group.

All 163 targeted communities will be randomly assigned to two cohorts as follows:
Cohort A: Approximately 8,400 smallholder farmers in 81 randomly selected communities will receive a lump-sum transfer of approximately 285 USD and two smaller transfers of 15 USD each.
Cohort B: Approximately 8,400 smallholder farmers in 82 randomly selected communities will receive three monthly transfers of approximately 105 USD each.

A subset of the targeted farmers will be interviewed (approx. 3,300).

Baseline
The project’s targeting and verification data will be used instead of baseline data to gauge key baseline indicators on farming practices, spending behaviors, and risk/time preferences.

Follow-up surveys
Round 1 of data collection is planned for July--August 2023. The objective is to administer it before the harvest starts. This survey will be short due to constraints that the evaluation needs to observe. The aim is to collect information limited to the FCS, FIES, and rCSI indicators.
Round 2 is scheduled for September 2023, which will be after all transfers are made and the harvest season is just starting.
Round 3 is scheduled for November--December 2023, at the tail end of the harvest season.
Round 4 is planned to take place one year after the intervention started as some of the outcomes targeted by the programme require a longer observation period.
