Abstract
The agricultural community has a challenge of increasing food production by more than 70% to meet demand from the global population increase by the mid-21st century. Sustainable food production involves the sustained availability of resources, such as water and energy, to agriculture. The key challenges to sustainable food production are population increase, increasing demands for food, climate change, and climate variability, decreasing per capita land and water resources. To discuss more details on (a) the challenges for sustainable food production and (b) mitigation options available, a special issue on “Water Management for Sustainable Food Production” was assembled. The special issue focused on issues such as irrigation using brackish water, virtual water trade, allocation of water resources, consequences of excess precipitation on crop yields, strategies to increase water productivity, rainwater harvesting, irrigation water management, deficit irrigation, and fertilization, environmental and socio-economic impacts, and irrigation water quality. Articles covered several water-related issues across the U.S., Asia, Middle-East, Africa, and Pakistan for sustainable food production. The articles in the special issue highlight the substantial impacts on agricultural production, water availability, and water quality in the face of increasing demands for food and energy.
Highlights
Sustainable food production involves the sustained availability of resources, such as water and energy, to agriculture
The key challenges to sustainable food production are population increase, availability of resources at the right time and place, threats posed by climate variability and extremes to land and water which are often exacerbated by other biophysical limits such as declining per-capita land and water scarcity, as well as rising demand for agricultural products [1,2]
There are opportunities for improving the water use efficiency and adjustment in its export portfolio of agricultural commodities by promoting the export of commodities with higher value and lower water use intensity. This special issue was organized to initiate an interdisciplinary dialogue with stakeholder groups about mitigation and adaptation strategies for sustainable agricultural production in the face of increasing demands due to population growth, urbanization, industrialization and agricultural intensification, and inadequate water resources management
Summary
Sustainable food production involves the sustained availability of resources, such as water and energy, to agriculture. The knowledge of managing water in agriculture with existing technology has not reached many parts of the world This special issue is developed to bring out the knowledge on water management towards sustainable food production in an open-access platform. Availability of water to agricultural production under historical past and projected future climate change (including floods, droughts, and extremes of precipitation and temperature). Sustaining agricultural production under population increase with existing water resources In this introductory article, we highlight the major findings from papers published in this collection. Management for Sustainable Food Production,” includes fifteen articles (thirteen are research articles, two review articles) These studies cover a wide range of topics related to water management for various crop production systems in different parts of the world
