Book (stand-alone)Agricultural Drainage Water Management in Arid and Semi-Arid Areas 2002
Also available in:
No results found.This publication provides planners, decision-makers and engineers with guidelines to sustain irrigated agriculture and at the same time to protect water resources from the negative impacts of agricultural drainage water disposal. On the basis of case studies from Central Asia, Egypt, India, Pakistan and the United States of America, it distinguishes four broad groups of drainage water management: water conservation, drainage water reuse, drainage water disposal and drainage water treatment. All these options have certain potential impacts on the hydrology and water quality in an area, with interactions and trade-offs occurring when more than one is applied. This publication presents a framework to help make a selection from among the various drainage water management options and to evaluate their impact and contribution towards development goals. In addition, it presents technical background and guidelines on each of the options to enable improved assessment of their impacts and to fac ilitate the preparation of drainage water management plans and designs. -
Book (stand-alone)Proceedings of the Second Meeting of the International Network of Salt-Affected Soils (INSAS)
Managing salt-affected soils for a sustainable future
2023Also available in:
No results found.The proceedings of the second meeting of the International Network of Salt-Affected Soils (INSAS) contain the abstracts of the papers presented during the workshop in Tashkent (22–26 May, 2023). The papers provide the up-to-date scientific knowledge and practical solutions for four topics: (1) mapping, assessing and monitoring of salt-affected soils; (2) sustainable management of salt-affected soils: practices and policy; (3) halophyte and saline agriculture and its effect on soil health; (4) integrated soil and water management under saline/sodic conditions. Under the first topic, modern techniques (geophysics, remote sensing, NIR spectroscopy) for mapping and monitroing of salt-affected soils as wel as mapping of environmental susceptibility to soil salinization in dry regions were presented. Under the second topic, different approaches to reclaim saline and sodic soils and improve seed germination including the use of different organic and inorganic amendments, organic biostimulants, biochar and phytoremediation were discussed. Moreover, biodiversity of salt-affected soils and its change along salinity gradient as well as the impact of soil enzymes on the structure and function of soil microbial communities and how soil degradation is associated with specific soil microbiota were reported. Policy gaps on addressing soil salinity were analyzed and further steps how to integrate agenda on SAS into existing agricultural policies were proposed. The results of Participatory Rural Appraisal approach to survey among farmers were provided. Under the third topic, the results on testing different conventional and non-conventional crops in field trials on salt-affected soils irrigated by fresh and saline water were reported. The influence of soil properties on growing halophytes was considered. Under the fourth topic, the ways to optimize the use of poor-quality irrigation water in agriculture were discussed. Some studies reported about the results of modeling of salt and water transport in soils for estimation of leaching requirement or root zone soil salinity. Several studies reported about the negative aspects of using brackish water leading to secondary soil salinization and sodification. For salt-affected areas with groundwater use for irrigation, the approach combining the Food Systems Approach and integrated water resources management was proposed to address the interdependent challenges of food and water security. -
BookletGood cropping practices and technologies to reduce the impact of natural hazards on maize production in Serbia 2021
Also available in:
The Serbian Ministry of Agriculture, Forestry and Water Management (MARW) is keen to increase the preparedness of maize producers to counteract the effects of natural hazards. Therefore, MARW has requested FAO to facilitate the writing of a technical guideline on good practices and technologies to reduce the impact of natural hazards. A workshop brought Serbian experts together to discuss the current knowledge on the impact of natural hazards on maize production in Serbia, and identify good practices and innovative technologies that could help to reduce the impacts of natural hazards. With climate change, it is expected that natural hazards, such as floods, droughts, storms, will increase in frequency and severity. Agriculture is one of the most climate sensitive sectors. Natural hazards may cause yield reductions or even total crop failure. In this brochure are described good agricultural practices and technologies to reduce the impact of natural hazards in maize production in Serbia, related to crop rotation, soil tillage, vertical tillage, mulching, growing cover crops, variety selection, sowing, inter-cropping, fertilization, weed and pest control, irrigation/drainage and harvesting. The brochure is intended for maize producers, ministries and entities of the Republic of Serbia, civil society, researchers/academics, agricultural extention services, and agricultural organizations. The brochure has been developed as one of the outputs of the FAO project ‘Enhancement of Disaster Risk Reduction and Management (DRRM) capacities and mainstreaming Climate Change Adaptation (CCA) practices into the Agricultural Sector in the Western Balkans’ (TCP/RER/3504).
