Naming fungi involved in spoilage of food, drink, and water النص الكامل
2015
Hawksworth, D. L.
Correct identifications are the key to all data on an organism. Fungi cultured or sequenced from a foodstuff may not always be the spoilage agents, and there are potential pit-falls in culturing and molecular identification. Molecular phylogenetics is resulting in major changes in fungal classification, and substantial changes in the rules on naming fungi were agreed in 2011. Different morphs of a single pleomorphic species can no longer have different scientific names, and stability is to be fostered through lists of protected names. The naming of fungi is becoming increasingly fit-for-purpose by taking advantage of the possibilities arising from advances in molecular and digital technologies. A list of the current names of 100 species of spoilage fungi is included.

2015
Mirzabaev, Alisher | Guta, Dawit | Goedecke, Jann | Gaur, Varun | Börner, Jan | Virchow, Detlef | Denich, Manfred | von Braun, Joachim
This article provides a review of trade-offs and synergies of bioenergy within the water–energy–food security nexus, with emphasis on developing countries. It explores the links of bioenergy with food security, poverty reduction, environmental sustainability, health, and gender equity. It concludes that applying the nexus perspective to analyses of bioenergy widens the scope for achieving multiple-win outcomes along the above aspects.
اظهر المزيد [+] اقل [-]Water resource decoupling in the MENA through food trade as a mechanism for circumventing national water scarcity النص الكامل
2015
Gilmont, Michael
This paper combines Food and Agriculture Organization (FAO) Food Balance data with Water Footprint data to reveal how virtual water flows interact with food import tonnages to enhance or retard national decoupling based on food trade. Decoupling theorises breaking the links between economic and population growth and water demands for domestic food production. The detailed analysis applies a resource decoupling model in relation to the role and potential of food and virtual water trade in alleviating national and regional water limits in the Middle East and North Africa (MENA). The contrast between Egypt’s political denial of dependence, and Israel’s strategic adoption of food imports provides an example.

2015
Miller, Kelly K. | Blaszczynski, Veronika N. | Weston, Michael A.
Bird feeding in residential gardens is an increasingly popular human–wildlife interaction. In Australia, the practice is discouraged by most government and nongovernment wildlife conservation agencies, although advice varies and the most common recommendation is to provide water and habitat for birds rather than supplementary food. This study compares bird abundance and diversity when residents in a Melbourne municipality provide water for birds versus food. Bird abundance was greater when food was provided compared with water, but avian assemblages did not differ.

Mejia, Francine Harriet | Baxter, Colden V. | Berntsen, Eric Karl | Fremier, Alexander K.
Materials, energy, and organisms from groundwater serve as resource subsidies to lotic systems. These subsidies influence food production and post-emergent fish growth and condition through nutrient inputs and water temperature changes. To test whether post-emergent fish grew faster in gaining sites, we grew hatchery post-emergent salmon in enclosures, sampled periphyton, benthic invertebrates and wild salmon, and modeled fish growth across a gradient of groundwater-surface water exchange. Fish grew almost twice as fast in gaining (2.7 % g d | The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Gruère, Guillaume P.; Narrod, Clare A.; Abbott, Linda
Nanotechnology is research and development that involves measuring and manipulating matter at the atomic, molecular, and supramolecular levels at scales measured in approximately 1 to 100 nanometers (nm) in at least one dimension.”Materials at such small scales often exhibit different electrical, magnetic, optical, mechanical, and other physical properties from their bulk material counterparts, leading to the development of potentially revolutionary technologies in a variety of industries,including agriculture and food. By increasing productivity, reducing postharvest loss, improving product quality, increasing the competitiveness of agricultural producers, and improving market access, advances in nanotechnology may present new opportunities to improve the livelihoods of the poor. But nanotechnology may also create new risks.Investments in agriculture and food nanotechnologies carry increasing weight because their potential benefits range from improved food quality and safety to reduced agricultural inputs and improved processing and nutrition. While most investment is made primarily in developed countries, research advancements provide glimpses of potential applications in agricultural, food, and water safety that could have significant impacts on rural populations in developing countries.Despite their promise, agricultural and food nanotechnologies, especially those that could reduce poverty or increase food and nutrition security, will likely face many challenges in each step of development—from investment in research and development (R&D) to adoption and use—before being commercialized and used by the rural poor. Many of these obstacles appear in the development of any new technology, but there are also issues specific to nanotechnology: intellectual property rights (IPR), the management of safety and environmental risks in the presence of wide uncertainties, and possible market displacement effects induced by these technologies, among other concerns. This brief presents a review of the potential opportunities and challenges of using nanotech applications for agriculture, food, and water in developing countries. | PR | IFPRI1; GRP1 | EPTD; MTID
اظهر المزيد [+] اقل [-]Achieving Water and Food Security in 2050: Outlook, Policies, and Investments النص الكامل
2015
Wichelns, Dennis
Food production in 2050 will be sufficient, globally, but many of the poor will remain food insecure. The primary cause of food insecurity will continue to be poverty, rather than inadequate food production. Thus, policies and investments that increase the incomes of the poor will remain the best ways to extend food security to all. Investments that promote growth in sustainable agriculture and provide non-farm employment opportunities in rural areas of lower income countries will be most helpful. There will be sufficient water, globally, to achieve food production goals and sustain rural and urban livelihoods, if we allocate and manage the resource wisely. Yet, water shortages will constrain agricultural production and limit incomes and livelihood opportunities in many areas. Policies and investments are needed to extend and ensure access to water for household use and agricultural production. Challenges requiring the attention of policy makers and investors include increasing urbanization and increasing demands for land and water resources. Policy makers must ensure that farmers retain access to the water they need for producing food and sustaining livelihoods, and they must create greater opportunities for women in agriculture. They must also motivate investments in new technologies that will enhance crop and livestock production, particularly for smallholders, and encourage the private sector to invest in activities that create employment opportunities in rural areas.
