Rural households in Sub-Saharan Africa face a number of binding constraints in agricultural production, including access to improved land, irrigation, improved seeds and fertilizer.  And where household members do not cooperate fully in their productive decisions, and women's access to the means of production is mainly through their husbands, women’s agricultural activities may be further constrained by less access to inputs, services, and credit relative to men.

The study randomly allocates access to irrigated plots of land via rental arrangement with Ariku Farms among interested households. And within each household to which Ariku Farms provides a land rental and/or inputs contract, we will randomly allocate the contract to either the husband or the wife.

The study’s key aim is to provide evidence on whether providing direct access for women to productive inputs alters production or consumption patterns in the household, including whether or not aggregate output, productivity, and intra-household efficiency increases. The study will also provide evidence on gains from access to irrigation, and will explore a number of secondary questions using incentivized lab-in-the-field measures.

Primary Outcomes
Primary Outcomes (end points)
This study will look at the impact of agricultural contracts on farmers’ productivity, quality of life and intra-household gender dynamics. The outcomes considered of primary importance for the study are (i) level of agricultural output; (ii) level of agricultural productivity; (iii) level of annual income; (iv) level of agricultural input use; (v) intra-household decision-making,control, and bargaining power between husband and wife; (vi) household efficiency: (vii) consumption patterns; (viii) time-use patterns; (ix) risk preferences.

Experimental Design
Experimental Design
The impact evaluation is designed as a randomized control trial that combines two cross-randomized components:
Randomization to irrigated plots: Because demand for access to the improved and irrigated plots is expected to exceed the supply of available plots, households that are both eligible to and interested in renting an irrigated plot will be randomized to either (i) no offer of an irrigated land rental contract, or (ii) an offer of a land rental contract for an irrigated plot. We will stratify the randomization based on community of residence, and marital status (monogamous or polygamous).
Randomization of irrigated land and/or inputs contract within the household: Within each household, we will randomly select whether the contracts for irrigated land rental and/or inputs are issued to the husband or wife. We will stratify the randomization based on whether they were interested in renting an irrigated plot, community of residence, and monogamous or polygamous.
The study will measure impact of access to irrigated land by comparing the treatment and control group. The study will also compare households in which wives sign contracts versus those in which husband sign contracts.

Randomization Method
Stratified randomization in stata
Randomization Unit
Treatment is randomized by household, defined as a man and his (designated) wife.
Was the treatment clustered?
Experiment Characteristics
Sample size: planned number of clusters
1,100 households
Sample size: planned number of observations
2,200 individuals
Sample size (or number of clusters) by treatment arms
Among households interested in receiving inputs on credit, we anticipate comparing 550 households in which the husband has been issued the credit contract to 550 households in which the wife has been issued the contract.
Among households interested in renting irrigated land under the contract offered, we anticipate assigning 260 to the treatment group and reserving a control group of 260. (This is due to the limited amount of land available for rental).
Among households assigned to receive irrigated land, we will compare 130 in which the husband receives the contract and 130 in which the wife receives the contract.
