Abstract
The growth in world population demands greater food production. Meanwhile, rainwater-harvesting systems (RWHS) have been used since ancient times to guarantee water supply for agriculture. Therefore, this research study reviews the conditions related to RWHS, focusing on rural communities. In this review, the methodologies used for rainwater harvesting (RWH) were determined, considering the characteristics for each of the hydraulic structures to guarantee runoff collection according to the basin area. Finally, the most relevant design parameters that should be considered in the planning and integral water resource management (IWRM) are identified, such as the soil type, average rainfall, and physiographic characteristics of the basin.
Highlights
The effect of climatic variability is experienced in diverse world regions, noticing that entire populations have water shortage problems
Local policies regarding the integral management of water resources have been limited, which has led to an increase of water shortage in urban and rural areas

Summary
The effect of climatic variability is experienced in diverse world regions, noticing that entire populations have water shortage problems. To carry out a study of the amount of water within an area, an availability analysis of water resources must be made; hydrological cycle conditions and water balance must be defined, which interrelates variables of precipitation, interception, temperature, surface runoff, and potential and actual evapotranspiration Among these variables, precipitation is the most important when talking about climate and hydrometeorology, since it is responsible for the changes to occur in patterns related to floods, droughts, losses in biodiversity, problems related to agricultural production, as well as those to infrastructure damage [12,13]. The type of soil, average rainfall, and physiographic characteristics are identified to constitute the most relevant design parameters for planning and suitable sites of the hydraulic structures that will guarantee an integral management of water resources (IMWR) in agriculture
