Special Issue Information

Dear Colleagues,

The conservation of water resources is a key aspect for the economic and environmental sustainability of all types of agricultural systems. Among all abiotic stresses, drought is the major constraint affecting plant physiological processes, causing huge production losses in agriculture. Water scarcity is very common in many areas of the world, and numerous studies deal with this topic, leading to the development of new irrigation strategies such as regulated deficit irrigation, partial root drying, and sustained deficit irrigation.

In this context, managing global water resources is one of the most pressing challenges of the twenty-first century, and there is a considerable pressure in agriculture to produce crops more efficiently by reducing water use. This knowledge is necessary to optimize a sustainable high-quality production without compromising the economic value of the crop, and thus, to propose best irrigation management practices.

This Special Issue aims at collecting original and quantitative studies dealing with any technique of irrigation management. Studies done in any type of crop (fruit trees species, forest, herbaceous, horticultural or ornamental crops) and under field or controlled environmental conditions are welcome. Submissions on the following topics are invited: (1) Development of deficit irrigation strategies and quantifying irrigation requirements in the development stages; 2) determination of the minimum water level for acceptable quality; (3) understanding of morphological and physiological plant response to water management; (4) assessment of the indices performance to detect water stress; and (5) identification of tolerance mechanisms development by the species to water stress and evaluation their adaptability to such conditions. Manuscripts where the management of irrigation with low quality waters is evaluated are particularly welcome, as marginal waters are very often used in deficit irrigation strategies.

Collaborative Action and Social Organization in Remote Rural Regions: Autonomous Irrigation Arrangements in the Pamirs of Tajikistan

This paper proposes a bottom–up “nexus medium” perspective to examine and understand social organization and how socio-ecological challenges in remote rural regions are dealt with in communities that receive only limited external support. While “nexus mediums” constitute substances, matter, or objects that combine manifold vital meanings and can be seen as socially constructed and materialized arenas of social interaction, autonomous resource management is seen as a means of local social organization. Taking water as the nexus medium of choice allows us to generate locally informed insights about the role of this scarce resource for the everyday life and social organization of communities inhabiting arid rural areas. This reasoning will be exemplified by three local case studies conducted during empirical research in the Pamirs of Tajikistan utilizing a mix of qualitative methods. The findings reveal how many fundamental everyday-life-related aspects and activities of the studied communities are related to water, and how these communities are organized around common water use and management arrangements that are based on joint decision-making, shared benefits and responsibilities, and collaborative action. The “nexus medium” concept appears to be an appropriate approach for research that seeks to understand from a local perspective how communal living is organized and how socio-ecological challenges are addressed.

The use of reclaimed water (RW) is considered as a means of maintaining agricultural productivity under drought conditions. However, RW may contain high concentrations of salts. The use of some practices, such as biofertilizers and organic substrates, is also becoming increasingly important in agricultural. production. The aim of this study was to evaluate the application of a mixed substrate (with coconut fibre) and arbuscular mycorrhizal fungi (AMF) on water relations, nutrient uptake and productivity in tomato plants irrigated with saline RW in a commercial greenhouse. Saline RW on its own caused a nutrient imbalance and negatively affected several physiological parameters. However, the high water-holding capacity of coconut fibre in the mixed substrate increased water and nutrient availability for the plants. As a consequence, leaf water potential, gas exchange, some fluorescence parameters (PhiPSII, Fv’/Fm’, qP and ETR) and fruit size and weight improved, even in control irrigation conditions. The use of AMF improved only some parameters because of the low percentage of colonization, suggesting that AMF effectiveness in commercial field conditions is slower and dependent of several factors.
