Book Description
This paper is a synthesis of IIMI's research on irrigation management for crop diversification in Indonesia, the Philippines and Sri Lanka. It provides some conclusions and recommendations, the potentials and constraints to more intensive non-rice production during the drier part of the year in irrigation systems that have been developed primarily for rice production. The research results obtained from selected irrigation systems sites in the three countries from 1985 to date were analyzed and compared by establishing common reference points where they existed, such as common constraints, potentials and institutional arrangements and by explaining differences based on observed data for each system. Relevant secondary data other than from the research sites were located to shed further insight in the synthesis.

Book Description
The resilience of food systems and security to emerging challenges and threats, especially in the context of environmental and climate risks and global pandemics such as the Covid-19 crisis, is currently gaining growing importance in research, policy, and practice. Based on this, the core focus of this book, as a part of a series of CERES publications, consists of identifiying and exploring the best ways to overcome such challenges and shocks and to build resilience in the Global South. More precisely, the book analyzes current dynamics and trends related to the climate resilience of food security and assess the relevance of emerging approaches such as climate-smart agriculture, new roles of agriculture extension, smart farming, and climate adaptation of farming systems.The book includes both conceptual and empirical research reporting lessons learned from many geographical, environmental, social, and policy settings while focusing on Africa, Middle East, and Asia. It also provides research and policy-oriented inputs and recommendations to guide change processes at multiple scales.

Book Description
Human health is closely linked with the health of the soil, which is both a vital resource for feeding the burgeoning global population via agriculture and vital to realizing most of the United Nations Sustainable Development Goals. However, increased salinization is significantly impacting the health of soil due to excess accumulation of varied salts (e.g., toxic ions including Cl− of Na+, HCO3−, Ca2+ and Mg2+, and sometimes SO42− and CO32−). Unfortunately, soil salinization has already affected about 20% of total arable land and 33% of irrigated land. Soil salinization negatively affects the health and productivity of plants and crops and thus threatens agriculture and food security worldwide. Moreover, it is predicted that by 2050, 16. 2 million ha of land will be affected by salt, which is predicted to cause 30%–50% yield losses worldwide. Making Plant Life Easier and Productive Under Salinity - Updates and Prospects provides a comprehensive overview of salinity and its major impacts. Chapters discuss important approaches for making plant life easier and more productive under salinity, the scale and complexity of salinity impacts on Sri Lankan rice farming systems, salinity stress responses of major metabolites, in vitro production of terpene in plants, the major mechanisms underlying phytohormone-mediated control of salinity impacts in plants, and genomics-assisted breeding approaches for achieving salinity tolerance in cereal crops.

Book Description
Improvements in rice growing technologies during the last two decades have resulted in a number of countries, especially in the humid tropical regions of Asia, nearing self-sufficiency in rice production. Consequently, policies are shifting in these countries toward minimizing the under-utilization of land by increasing the cropping intensity of irrigated areas, particularly by growing non-rice crops during the dry season. These workshop papers discuss the advantages of and constraints to crop diversification in different country situations throughout Asia.
