    CropSyst is the crop growth model chosen as a decision tool for the Tadla Benchmark project. CropSyst is a daily time step simulation model. The model was developed to serve as an analytic tool to study the effect of cropping systems management on productivity and the environment. The model simulates the soil water budget, soil– plant nitrogen budget, crop canopy and root growth, dry matter production, yield, residue production, and decomposition. Management options include cultivar selection, crop rotation, irrigation, nitrogen fertilization, tillage operations, and residue management.

    Around 2.5 billion people – 30 percent of the world’s population – live in the dry areas, which cover more than 40 percent of the world’s land surface. Scarce natural resources, land degradation and frequent droughts severely challenge food production in these areas. Both North Africa (Morocco, Algeria, Tunisia) and the North East of Brazil fall under arid and semi-arid climate. Cacti have developed phenological, physiological and structural adaptations for growth and survival in arid environments where they have multiple functions (food, feed, soil conservation, etc.).

    Few regions present bigger development challenges than the African drylands – home to nearly 300 million people, and the vast majority of Africa’s poor. Food security and rural welfare in these areas are limited by a range of factors, biophysical, socio-economic and policy-related. And many of the biggest challenges – poverty, drought, land degradation, food insecurity – will be exacerbated by climate change.

    This document presents the Strategic Plan of the International Center for Agricultural Research in the Dry Areas for the period from 2017 to 2026. ICARDA’s mission is to enhance food, water, and nutritional security and environmental health in the face of global challenges, including climate change. Through preparedness for change and productivity gains in the rural economy, ICARDA will contribute to poverty reduction and social stability as our overarching goal. Innovative science, partnerships for impact, capacity development, and a fit-for-purpose organization are our tools.

    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.

    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
