GAW Report, 203. The Atmospheric Input of Chemicals to the Ocean
World Meteorological Organization (WMO) ; International Maritime Organization (IMO); Food and Agriculture Organization (FAO); et al. - WMO, 2012The atmospheric input of chemicals to the ocean is closely related to a number of important global change issues. The increasing input of atmospheric anthropogenic nitrogen species to much of the ocean may cause a low level fertilization of the ocean that could result in an increase in marine 'new' productivity of up to ~3% and thus impact carbon drawdown from the atmosphere. However, the increase in nitrogen inputs are also likely to increase the formation of nitrous oxide in the ocean. The increased emission of this powerful greenhouse gas will partially offset the climate forcing impact res ...

Published by: WMO ; 2012The atmospheric input of chemicals to the ocean is closely related to a number of important global change issues. The increasing input of atmospheric anthropogenic nitrogen species to much of the ocean may cause a low level fertilization of the ocean that could result in an increase in marine 'new' productivity of up to ~3% and thus impact carbon drawdown from the atmosphere. However, the increase in nitrogen inputs are also likely to increase the formation of nitrous oxide in the ocean. The increased emission of this powerful greenhouse gas will partially offset the climate forcing impact resulting from the increase in carbon dioxide drawdown produced by N fertilization. Similarly, much of the oceanic iron, which is a limiting nutrient in many areas of the ocean, originates from the atmospheric input of minerals as a result of the long-range transport of mineral dust from continental regions. The increased supply of soluble phosphorus from atmospheric anthropogenic sources (through large-scale use in fertilizers) may also have a significant impact on surface-ocean biogeochemistry, but estimates are highly uncertain. While it is possible that the inputs of sulphur and nitrogen oxides from the atmosphere can add to the rates of ocean acidification occurring due to rising levels of carbon dioxide, there is too little information on these processes to assess the potential impact. These inputs may be particularly critical in heavily trafficked shipping lanes and in ocean regions proximate to highly industrialized land areas. Other atmospheric substances may also have an impact on the ocean, in particular lead, cadmium, and POPs. GESAMP initiated Working Group 38, The Atmospheric Input of Chemicals to the Ocean, to address these issues.

The state of food and agriculture: investing in agriculture for a better future
FAO, 2012Recent food crises and growing concerns about global climate change have placed agriculture on top of the international agenda. Decision-makers have recognised the strong link between the dual goals of eradicating hunger and making agriculture sustainable. Achieving these goals will require a significant increase in agricultural investment but, more importantly, it will require improving the quality of this investment.

Recent food crises and growing concerns about global climate change have placed agriculture on top of the international agenda. Decision-makers have recognised the strong link between the dual goals of eradicating hunger and making agriculture sustainable. Achieving these goals will require a significant increase in agricultural investment but, more importantly, it will require improving the quality of this investment. This annual flagship report by the Food and Agriculture Organization (FAO) reviews the economic and social rationale for agricultural investment, examines the causes of underinvestment, and presents evidence showing how public resources can be used more effectively to catalyse private investment, especially by farmers themselves, and to channel public and private resources towards more socially beneficial outcomes. The focus of the report is on the accumulation of capital by farmers in agriculture and the investments made by governments to facilitate this accumulation.

Potential effects of climate change on crop pollination
Crop production must meet the demands of feeding a growing population in an increasingly degraded environment amid uncertainties resulting from climate change. there is a pressing need to adapt farming systems to meet these challenges. one of agriculture’s greatest assets in meeting them is nature itself: many of the ecosystem services provided by nature – such as nutrient cycling, pest regulation and pollination – directly contribute to agricultural production. the healthy functioning of these ecosystem services ensures the sustainability of agriculture as it intensifies to meet growing deman ...

Crop production must meet the demands of feeding a growing population in an increasingly degraded environment amid uncertainties resulting from climate change. there is a pressing need to adapt farming systems to meet these challenges. one of agriculture’s greatest assets in meeting them is nature itself: many of the ecosystem services provided by nature – such as nutrient cycling, pest regulation and pollination – directly contribute to agricultural production. the healthy functioning of these ecosystem services ensures the sustainability of agriculture as it intensifies to meet growing demands for food production. Climate change has the potential to severely impact ecosystem services such as pollination. as with any change, both challenges and opportunities can be expected. recognizing that the interactions between climate, crops and biodiversity are complex and not always well understood, the plant production and protection division of fao has coordinated this review of the potential effects of climate change on crop pollination. By taking a comprehensive, ecosystem approach to crop production, it may be possible to build in greater resilience in farming systems, and to identify broader options for crop production intensification through the deliberate management of biodiversity and ecosystem services. Prefaceviii within the context of its lead role in the implementation of the international initiative for the Conservation and sustainable use of pollinators, also known as the international pollinators initiative (ipi) of the united nations Convention on Biological diversity, established in 2000 (Conference of parties decision v/5, section ii), fao has developed a global action on pollination services for sustainable agriculture. this report serves as a contribution by fao’s global action on pollination services to the objectives of the ipi, specifically its first objective to “Monitor pollinator decline, its causes and its impact on pollination services”

Greening the economy with climate-smart agriculture
Agriculture has to address simultaneously three intertwined challenges: ensuring food security through increased productivity and income, adapting to climate change and contributing to climate change mitigation. To accomplish this, food systems have to become, at the same time, more efficient and resilient, at every scale from the farm level to the global level. Radical changes are needed in agricultural and food systems. These changes can play an essential role in greening the economy and contributing to sustainable development. This paper considers the intertwined challenges of food sec ...

Good Practices in Building Innovative Rural Institutions to Increase Food Security
Continued population growth, urbanization and rising incomes are likely to continue to put pressure on food demand. International prices for most agricultural commodities are set to remain at 2010 levels or higher, at least for the next decade (OECD-FAO, 2010). Small-scale producers in many developing countries were not able to reap the benefits of high food prices during the 2007-2008 food price crises. Yet, this upward food price trend could have been an opportunity for them to increase their incomes and food security. The opportunity that high food prices could have provided as a pat ...

Crop yield response to water
Steduto Pasquale; Hsiao Theodore C.; Fereres Elias; et al. - FAO, 2012 (FAO irrigation and drainage paper-No. 66)Food production and water use are inextricably linked. Water has always been the main factor limiting crop production in much of the world where rainfall is insufficient to meet crop demand. With the ever-increasing competition for finite water resources worldwide and the steadily rising demand for agricultural commodities, the call to improve the efficiency and productivity of water use for crop production, to ensure future food security and address the uncertainties associated with climate change, has never been more urgent.

Adaptation to climate change in semi-arid environments: experience and lessons from Mozambique
FAO, 2012 (Environment and Natural Resources Management-No. 19)Southern Africa and Mozambique are highly vulnerable to the impacts of climate change. The region is frequently exposed to droughts, floods, variable rainfall and heat, which are expected to worsen, and sensitivity to such exposure of the natural resource-based livelihood system is very high. The project area is remote and highly underdeveloped and the population is poor, food insecure, and not resilient to the impact of climate shocks. Due to water scarcity, not sufficient for humans and livestock except in a few communities along the Limpopo River, livelihood options are limited. Livelihoods ...
