For this reason, a study was undertaken in order to determine monthly irrigation requirements for three study sites, for both vegetables and sugarcane. A proper scientific methodology was applied to achieve this information on crop water requirements in Jamaica for the first time. In addition, the cumulative frequencies of monthly and seasonal rainfall depths were analyzed, and this information used to develop monthly rainfall values, as well as seasonal rainfall values for different return periods for the sites. Each study site was found to be unique in its irrigation requirements, which highlights the climatic and soil variability across the island. However, all three sites were similar in their need for irrigation during the months of March and April for vegetables, signifying that this is a universally dry period across the island. This information is meant to provide a foundation for irrigation planning and water management strategies during water‐scarce conditions.

Kohn","doi":"10.1002/ird.1826","DOIUrl":"https://doi.org/10.1002/ird.1826","url":null,"abstract":"Whereas the importance of traditional irrigation in southern Europe is well known, its role in the ecological history of rural landscapes elsewhere in Europe is often overlooked. This two‐part review aims to advance understanding of the historical and present role of traditional irrigation farming schemes in Europe. It confirms that, prior to the industrial era, irrigation had been an essential part of farming for centuries. It was practised in very different, often contrasting, environmental regions across Europe. The historical spread of the schemes is presented in a map. Two ‘golden ages’ of traditional irrigation in Europe can be identified: the first in the High Middle Ages along with the introduction and widespread adoption of the three‐field system, and the second in the late eighteenth up to the first half of the twentieth century with reorganization of this agricultural system. Due to the complex character of past irrigation functioning, scientific understanding of processes and long‐term impacts is difficult, but ultimately all irrigation farming enterprises were driven by the purpose of increasing yields. Apparently the traditional schemes were the result of an evolution process over the course of centuries characterized by steady optimization and adaptation to historic and local conditions.

Jiménez","doi":"10.1002/IRD.183","DOIUrl":"https://doi.org/10.1002/IRD.183","url":null,"abstract":"This paper explains how regulations and technology required for efficient and safe reuse of wastewater in irrigated agriculture were developed, considering both farmers' needs and health protection measures in Mexico, where a significant amount of municipal wastewater is reused for agriculture. Instead of considering nutrients and organic matter as pollutants, new legislation was developed allowing them to be present in appropriate concentrations in wastewater, while pathogens, especially helminth ova, had to be removed prior to wastewater reuse. Therefore, tailor‐made research work to develop technology that would treat wastewater to fit the new definition of effluent quality was undertaken. To illustrate the process, the Tula Valley case, where the biggest compact irrigation area using wastewater in the world is located, is discussed. The more than 100‐year experience in reusing wastewater in the Tula Valley has made it possible to study the short‐ and long‐term effects discussed below. The technology developed is called APT (advanced primary treatment) that basically consists of a coagulation–flocculation process coupled with high‐rate sedimentation. It is concluded that with an appropriate regulation and wastewater treatment technology a win–win approach to safely reuse wastewater in agriculture at an affordable cost may be possible.

Abaidoo","doi":"10.1002/IRD.185","DOIUrl":"https://doi.org/10.1002/IRD.185","url":null,"abstract":"Microbiological water and crop contamination was monitored on urban vegetable farms in Ghana. Faecal coliform and helminth egg contamination levels of irrigation water from drains, streams and shallow wells significantly exceeded WHO recommendations for unrestricted irrigation. High faecal coliform levels exceeding common guidelines for food quality were also recorded on lettuce irrespective of the irrigation water source, with significantly lower coliform concentrations on lettuce irrigated with piped water than with shallow well or stream water. Higher crop contamination levels were observed in the rainy season in spite of lower irrigation frequencies, compared to the dry season. The main species of helminth eggs isolated in water and on lettuce were Ascaris lumbrecoides, Hymenolepis diminuta, Fasciola hepatica and Strogyloides larvae. Results from field trials showed that apart from wastewater, already contaminated soil as well as poultry manure also contribute to crop contamination, but contributions from these sources could be only partially quantified. The need to reduce the potential health risks resulting from faecal coliform and helminth contamination of urban and peri‐urban vegetables thus needs a more holistic approach than a simple focus on irrigation water quality.
