Papers on mycobacteria in food, feed and water, published between 1945 and 2010 and indexed in the database Web of Science (Thomson Reuters), were ranked according to authors, institutions, countries and source titles. The total number of papers on mycobacteria and food, and mycobacteria and water were 1,486 and 1,419, respectively. More than 40% of papers have been published in the last five years. In addition to publications in peer reviewed journals the archives of ProMED-mail and the Rapid Alert System for Food and Feed of the European Union were also searched. It is evident that much attention is being paid to mycobacteria in food, feed and water as they likely pose a public health risk.

2018

Food security is a critical issue for the Arabian Peninsula countries due fast population growth, reduced domestic food production and the tighter global food markets because of trading partners�?? strained export surpluses. Water scarcity is a major concern for the AP. The renewable water resources per capita is considered the lowest in the world and has decreased from 1250 m3 in 1950 to 76.2 m3 in 2014. Furthermore, the projected water demand in AP for the year 2025 will exceed the double of the current groundwater availability, estimated at 8030M m3. In response to the alarming water situation, ICARDA in collaboration with the National Agricultural and Extension Systems (NARES) has established a program in AP, which has developed, evaluated, and introduced technology packages that empower growers to produce high-quality crops with less water. These technologies include: 1) the integrated forage production system based on indigenous plant species; 2) the introduction of spineless cactus as animal feed; and 3) protected agriculture with associated developed technologies such as soilless culture (hydroponics). Similarly, ICARDA and NARS works on date palm has resulted in improving water and land productivity for date production. Such water saving technology packages are being transferred to farmers in AP region through ICARDA and National scientists and extension agents. Conclusively, a noticeable impact on the on-farm water management through the increased productivity per unit of water and land created. The demand for more applied research in the region is inevitable to ensure an adequate level of food security based on Climate-smart agriculture practice | Azaiez Ouled Belgacem, Arash Nejatian, Mohamed Ben-Salah, Ahmed Moustafa.

2003
Binns, J.A. | Maconachie, R.A. | Tanko, A.I.
In sub-Saharan Africa, urban and peri-urban food production has been identified as an important resource for meeting the challenges of rapidly growing cities, and the positive aspects of such production have been well documented in the literature. This paper examines some of the health and environmental concerns associated with urban and peri-urban agriculture (UPA). Empirical evidence from the city of Kano in northern Nigeria suggests that there is currently much reason for concern as industrial and domestic toxins are reaching dangerously high levels. As soils and water channels become increasingly polluted, the sustainability of urban and peri-urban food production is questioned. Since the health implications of long-term exposure to toxins are unclear, it is suggested that coordinated longitudinal research involving urban planners, agricultural scientists and health specialists is urgently needed. In addition, it remains crucial that government and institutional actors effectively monitor and enforce both environmental and zoning by-laws, if the health and environmental constraints of UPA are to be overcome, and the future sustainability of production is to be assured.

Delivering access to sufficient food, energy and water resources to ensure human wellbeing is a major concern for governments worldwide. However, it is crucial to account for the ‘nexus’ of interactions between these natural resources and the consequent implications for human wellbeing. The private sector has a critical role in driving positive change towards more sustainable nexus management and could reap considerable benefits from collaboration with researchers to devise solutions to some of the foremost sustainability challenges of today. Yet opportunities are missed because the private sector is rarely involved in the formulation of deliverable research priorities. We convened senior research scientists and influential business leaders to collaboratively identify the top forty questions that, if answered, would best help companies understand and manage their food-energy-water-environment nexus dependencies and impacts. Codification of the top order nexus themes highlighted research priorities around development of pragmatic yet credible tools that allow businesses to incorporate nexus interactions into their decision-making; demonstration of the business case for more sustainable nexus management; identification of the most effective levers for behaviour change; and understanding incentives or circumstances that allow individuals and businesses to take a leadership stance. Greater investment in the complex but productive relations between the private sector and research community will create deeper and more meaningful collaboration and cooperation.

2019
Gohar, Abdelaziz A. | Cashman, Adrian | Ward, Frank A.
Climate-stressed groundwater resources present a growing challenge for protecting food security and economic sustainability, notably in Small Island Developing States (SIDS). These states are some of the most vulnerable to climate stress because of their large coastlines, vulnerability to rising sea levels, weak access to reliable surface water, and limited food production capacity for handling increased groundwater scarcity. Impacts of climate stressed groundwater resources brought on by irrigation and growing urban demand in SIDS continue to receive widespread attention by both scientists and policymakers. Policies that limit pumping to protect aquifer sustainability reduce short-term economic welfare by unknown amounts that would otherwise be secured by both urban and irrigation water users. Yet, little scholarly research has addressed economic impacts of climate-water stress for the special needs of SIDS for which urban and irrigation pumping compete hydrologically and economically over long time periods. The original contribution of this work is to address that gap by employing downscaled data on precipitation from Representative Concentration Pathways (RCP) climate scenarios. Its novel contribution is to conceptualize, develop, apply, and interpret an integrated hydro-economic framework to understand interconnected physical and economic linkages from managing an unconfined regional aquifer system under each of three climate and two policy scenarios. The application is to Barbados, a SIDS, for which current and future irrigation and urban demands compete for water. The framework integrates groundwater hydrology, climate scenarios, economics, land use, and groundwater management, with the intent to mitigate impacts of climate stress on current economic values of water as well as protecting future aquifer sustainability. Results provide a framework to guide water management for SIDS vulnerable to climate stress for which water of the right quantity, quality, timing, location, and price are essential elements of economic development.
