Iran faces environmental challenges such as erosion and extreme events, namely droughts and floods. These phenomena have frequently affected the country over the past decades and temperature rise has led to a more challenging situation. Iran started to implement national and provincial policies in the 1950s to cope with these phenomena. To provide an overview of Iran’s efforts to tackle land degradation and climate change, this paper examined through literature since 2000 the stakeholders’ policies, their interventions and obstacles to the mitigation of these environmental challenges. Government, non-governmental organizations (NGOs), and international projects have been the primary actors. Erosion-sensitive soil plantation, drought-resistant seeds, and water-saving irrigation systems were the main interventions of these policies. However, the research stresses the lack of coordination between these stakeholders, and the absence of a comprehensive database that could enable climate change to be tackled better in the future.

Based on remotely sensed imagery and socioeconomic data, this research analyzes the reasons why farmers choose one crop over another in the Bekaa Valley in Lebanon. This study mapped the area of the cultivated crop in 2017 with Sentinel-2 images. An accurate and new method was developed to extract the field boundaries from the evolution of the normalized difference vegetation index (NDVI) profile throughout the season. We collected 386 GPS locations for fields that are used for crop cultivation, from which the NDVI profile was extracted. The 386 reference fields were separated into two groups: reference locations and test locations. The Euclidean distance (ED) was calculated between these two groups, and the classification was strongly correlated to the known crop type in the field (overall accuracy: 90%). Our study area cultivated wheat (32%), spring potatoes (25%), spring vegetables (27%), orchards (11%), vineyards (7%), and alfalfa (<1%). Socioeconomic surveys showed that farmers favored these crops over others on account of their profitability. Nonetheless, the surveys highlighted a paradox: despite the lack of a political frame for agriculture in Lebanon, farmers’ crop choices strongly depend on a few existing policies.

Water is a valuable resource for which demand often exceeds supply in dry climates. Managing limited water resources becomes increasingly difficult in circumstances of recurring drought, rising populations, rapid urbanisation, industrial development, and financial constraints, such as occur in Iran. Newspapers both report on and influence people’s understanding of water-related issues. An analysis was undertaken of two major Iranian daily newspapers over a 7-year period. Structure Query Language (SQL) was employed to identify relationships among a total of 1275 records/fields which were extracted from 84 water-related news items. They were analysed for message, contributor, spatiality and allocated space. Of the water-related items, wetlands comprised 33% (class), public awareness 54% (message), local level 56% (spatiality), and authorities 53% (contributor). Space allocation on each page was mostly <40% (94% of items). Four examples were highlighted of ambitious engineering projects adopted in response to water distribution issues. It is concluded that the general lack of educating messages about water use efficiency in rural areas and water consumption in cities does not assist in developing positive water-saving local behaviours. Newspapers could be a useful tool in a broader strategy for addressing and managing the demand side of the water crisis in Iran.
