This report presents a comprehensive land cover map of Tunisia, highlighting cultivated land, olive trees, dates and orchards while integrating information on land water management practices. [Author] A land cover map was derived using Sentinel-2 satellite imagery and stratified with water management data from currently existing data. [Author] Statistics illustrating the area of each class regionally and nationally were produced to provide accurate information on land cover classes distribution. [Author] Land cover information is essential to understanding the diverse range of ecosystems and agricultural land in Tunisia, particularly when looking to address climactic and socioeconomic challenges in the country. [Author] An accurate representation of agricultural land use is imperative when developing strategies for natural resource management and sustainable agricultural practices. [Author] Land cover mapping within the SolaWISe initiative facilities access to essential information on soil, land water and crop management, thus informing decision-making processes for enhancing agricultural productivity and sustainability. [Author] This land cover map provides a robust foundation for developing insights into natural resource management and agricultural practices across Tunisia. [Author] It empowers stakeholders at national, regional and local levels to make informed decisions for sustainable crop production in the context of a changing climate. [Author] There is no information on water management practices in the south of Tunisia; producing these datasets would significantly improve our understanding of crop management systems and agricultural water productivity. [Author] In the future land cover maps can be expanded to include more intricate irrigation and crop type information, allowing stakeholders to develop a more intricate understanding of spatial variation in crop suitability and productivity.

This book focuses on monitoring and assessing various environmental processes in Tunisia using state-of-the-art remote sensing and GIS technologies. In addition to addressing the diversity of Tunisian landscapes and providing spatial analysis of natural, cultivated and urbanized environments. It presents and discusses several case studies on integrated RS / GIS approaches for mapping, modeling, monitoring and evaluation. Moreover, in this volume authored by experts in the topic from Tunisia and other countries, authors assess the agro-environmental applications from Tunisia and offer different methods and applications to environmental processes and risks including drought, degradation, flood, planning, Yield estimation, dust storm detection, dry land vulnerability, wetland dynamics and others. The material presented here will help decision-makers plan sustainable landscape and agricultural management policies that preserve biodiversity and contribute to achieving sustainability goals and for researchers, it will expose methodological approaches used in different fields of research. Graduate students and Practionioner engineers working in the field of RS/GIS will also benefit from the book. The book ends with a set of conclusions and recommendations to support researchers underscoring the need for further research in this area.

This work becomes with methodological rigor a part of the innovative proposals for the characterization of the areas at risk of desertification. The complexity of the phenomenon of desertification, which involves extended surfaces in all continents, is one of the most alarming processes of the environmental degradation of our Planet and threatens the health and the living conditions of over a billion of persons. The food crisis, in continuous increase, ask for the world of research to urgently supply reassuring solutions concerning the acquisition of indicators, which are easy to monitor and concur to control the phenomenon in order to fight its acceleration. The constant but different combination that determines the diffusion of deserti- cation in the territories, attributable mostly to climatic changes and the activities of the man, makes our job challenging and complicated, since it varies from region to region. We are aware of all this and therefore we think that the methodological approach of survey of the data is an extremely important element to locate of the phenomenon and to monitor its course. This work, which is characterized for its multi-disciplinary approach, suggests solutions that we wish will quickly find concrete applications at international level.

Environmental information and systems play a major role in environmental decision making. As such, it is vital to understand the impact that they have on different aspects of sustainable environmental management, as well as to understand the opportunism they might present for further improvement. Environmental Information Systems: Concepts, Methodologies, Tools, and Applications is an innovative reference source containing the latest research on the use of information systems to track and organize environmental data for use in an overall environmental management system. Highlighting a range of topics such as environmental analysis, remote sensing, and geographic information science, this multi-volume book is designed for engineers, data scientists, practitioners, academicians, and researchers interested in all aspects of environmental information systems.

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.
