    Field experiments were carried out during four cropping seasons (summer 2013, winter 2013/14, summer 2014 and winter 2014/15) to evaluate sustainable interventions to combat degradation associated with salt accumulation. Field trials were conducted with various treatments including application of gypsum, organic matter, bio-fertilizers, ammonia injection, and installation of mole drains.

    Stipagrostis pungens is a perennial grass species which belongs to the Poaceae family. It is usually found with several erect culms, grows up to 1.5 m in height, and forms substantial tufts. It is a tall stiff glabrous grass with pungent leaves, and a C4 grass with sclerophyllous, spine-tipped, inrolled leaves, with sunken stomata. The root system extends laterally for a radius of 20 m or more. The roots are covered throughout their length by a sandy sheath, which is penetrated by the root hairs that occur throughout the entire length of the sheath.

    Widespread heat waves, floods, and droughts last year were a strong reminder of the threats posed by climate change. In the non-tropical dry areas where ICARDA works we are becoming accustomed to record high temperatures and increasing water scarcity year on year. Resilience and climate change adaptation are at the heart of ICARDA’s new Strategic Plan 2017-2026 – a bold and ambitious effort to harness cutting-edge science and deliver the tools and technologies that smallholder farmers need to maintain agricultural production and protect their livelihoods.

    In this study, an economic evaluation of water-use efficiency technologies proposed and tested by the agronomic team in the Tadla Irrigated Perimeter was carried out. To capture climatic variability, the analysis was conducted during two contrasting years (dry and wet). Total annual rainfall was 357 mm in 2005/06 (wet year) and 296 mm in 2006/07 (dry year). During the first year, precipitation was well distributed throughout the season. However, the second year was wet at the beginning, dry in the middle and very wet at the end of the season.

    The study was conducted in El-Serw (New Alexandria) located about 32 km south of Damietta, Damietta Governorate, El-Manzala Lake is to the east, Dakahlia Governorate lies to the south, and to the west are El-Sharqawia canal and the Nile River.
    The selected site has the general characteristics of marginal lands:
    • Drainage system problems;
    • High water table;
    • Increased soil salinity;
    • Seawater intrusion;
    • Pollution due to extensive use of chemicals; low water quality;
    • Available water increases relatively in winter;

    This report describes the use of improved methodologies developed to identify suitable watersheds based on an integrated resources management concept. The approach integrates multi-disciplinary knowledge, GIS utilities, and verification in the field to develop and test a methodology to identify watersheds with specific characteristics
    – in this case, the watersheds most suited to the project activities.

    The agricultural development on newly reclaimed lands has led to many national debates about food
    security and budget deficits, and the living conditions of the new settlers at the local level. This debate
    is still crucial for present day Egypt, a country facing major challenges, including food security, agriculture
    modernization, employment generation, and land fragmentation due to dramatic population growth.
    In this context, policy makers are always seeking the best land allocation system for these new lands. This

    This issue of Caravan describes the new program, and some of the research innovations it will build on. The issue begins with two ‘opinion pieces’ by scientists from partner organizations in the CRP. They share lessons learnt from past successes (and failures), and ideas that could be applied to dryland
