Fig. 3: Number of small-scale farms in water scarce regions compared to research coverage.
From: A scoping review of research funding for small-scale farmers in water scarce regions
Each point represents the number of small-scale farms in a country that are in water scarce regions. The size of the points corresponds to the number of studies that measured the impact of an intervention on the incomes and/or yields of small-scale farmers in water scarce regions. The colours indicate the economic grouping of the countries as low, lower-middle or upper-middle income.
