This report presents a summary of the methodology and results and a comprehensive global assessment of the world’s agricultural ecology. The national-level information with global coverage enables knowledge-based decisions for sustainable agricultural development. The Agro-ecological Zones approach is a GIS-based modeling framework that combines land evaluation methods with socioeconomic and multiple-criteria analysis to evaluate spatial and dynamic aspects of agriculture. The results of the Global AEZ assessment are estimated by grid cell and aggregated to national, regional, and global levels. They include identification of areas with specific climate, soil, and terrain constraints to crop production; estimation of the extent and productivity of rain-fed and irrigated cultivable land and potential for expansion; quantification of cultivation potential of land currently in forest ecosystems; and impacts of climate change on food production, geographical shifts of cultivable land, and implications for food security.

Close to one billion people in the world are undernourished and world population is expected to increase by 30% to approximately 9 billion by 2050 while food demand is expected to double. There is increasing competition for land and water resources from other sectors and increasing competitive demand for agricultural products for biofuel production. The UN’s Millenium Development Goal of reducing the number of undernourished to less than 420 million by 2015 has placed additional emphasis on the question of how we can secure food for the current and future populations and where the additional food requirement can be produced. One world region that possesses significant potential for improvements in agricultural output is the Semi-Arid Tropics (SAT), which lie primarily in developing countries where agriculture is almost entirely rainfed and largely comprises poor, smallholder farms. Due to a variety of factors including high climatic variability in time and space, poverty and poor education, poor policy and institutional support, and political instability, many areas within the SAT are far from reaching their potential agricultural production. Developing their full agricultural potential would help these areas feed their often rapidly growing populations as well as reduce poverty, boost their economies and provide more food for world markets. In this report, IIASA’s Agro-Ecological Zones (AEZ) methodology is applied to assess the agricultural potential of the semi-arid tropics and compare it to currently reported yields. Yield potentials are calculated for rain-fed conditions under high inputs and advanced management to show how much yields can be improved. Furthermore, the AEZ methodology is adjusted to model the impacts on yield potentials of water management techniques such as rainwater harvesting and soil moisture management. Bio-physical constraints to agriculture and the impacts of climate change are also analyzed with AEZ. Results indicate that modeled potential yields under high inputs and advanced management are on average 3.6 times more than the current average yields in countries under the SAT. Soil moisture management and rainwater harvesting practices could add an additional 10% on average to these high input potentials while further reducing the variability in yields and number of failure years. Climate change impacts are slightly positive for the SAT as a whole, but all results in the study vary considerably depending on the crop and the region.

To sustain growing food demand and increasing standard of living, global water use increased by nearly 6 times during the last 100 years, and continues to grow. As water demands get closer and closer to the water availability in many regions, each drop of water becomes increasingly valuable and water must be managed more efficiently and intensively. However, soaring water use worsens water scarcity conditions already prevalent in semi-arid and arid regions, increasing uncertainty for sustainable food production and economic development. Planning for future development and investments requires that we prepare water projections for the future. However, estimations are complicated because the future of the world's waters will be influenced by a combination of environmental, social, economic, and political factors, and there is only limited knowledge and data available about freshwater resources and how they are being used. The Water Futures and Solutions (WFaS) initiative coordinates its work with other ongoing scenario efforts for the sake of establishing a consistent set of new global water scenarios based on the shared socio-economic pathways (SSPs) and the representative concentration pathways (RCPs). The WFaS "fast-track" assessment uses three global water models, namely H08, PCR-GLOBWB, and WaterGAP. This study assesses the state of the art for estimating and projecting water use regionally and globally in a consistent manner. It provides an overview of different approaches, the uncertainty, strengths and weaknesses of the various estimation methods, types of management and policy decisions for which the current estimation methods are useful. We also discuss additional information most needed to be able to improve water use estimates and be able to assess a greater range of management options across the water–energy–climate nexus.

The Water Futures and Solutions Initiative (WFaS) is a cross-sector, collaborative global project. Its objective is to developing scientific evidence and applying systems analysis to help identify water-related policies and management practices that work together consistently across scales and sectors to improve human well-being through water security. The Water Futures and Solutions (WFaS) initiative has produced a consistent and comprehensive projection for global possible water futures. Focusing on the near future until the 2050s, WFaS assessed how water future changes over time, employing a multi-model projection.

Sustainable development demands reliable water resources, yet traditional water management has broadly failed to avoid environmental degradation and contain infrastructure costs. We explore the global-scale feasibility of combining natural capital with engineering-based (green-gray) approaches to meet water security threats over the 21st century. Threats to water resource systems are projected to rise throughout this period, together with a significant expansion in engineering deployments and progressive loss of natural capital. In many parts of the world, strong path dependencies are projected to arise from the legacy of prior environmental degradation that constrains future water management to a heavy reliance on engineering-based approaches. Elsewhere, retaining existing stocks of natural capital creates opportunities to employ blended green-gray water infrastructure. By 2050, annual engineering expenditures are projected to triple to $2.3 trillion, invested mainly in developing economies. In contrast, preserving natural capital for threat suppression represents a potential $3.0 trillion in avoided replacement costs by mid-century. Society pays a premium whenever these nature-based assets are lost, as the engineering costs necessary to achieve an equivalent level of threat management are, on average, twice as expensive. Countries projected to rapidly expand their engineering investments while losing natural capital will be most constrained in realizing green-gray water management. The situation is expected to be most restrictive across the developing world, where the economic, technical, and governance capacities to overcome such challenges remain limited. Our results demonstrate that policies that support blended green-gray approaches offer a pathway to future global water security but will require a strategic commitment to preserving natural capital. Absent such stewardship, the costs of water resource infrastructure and services will likely rise substantially and frustrate efforts to attain universal and sustainable water security.
