This lesson provides an overview of the primary influences of watershed and channel sedimentation. In a short narrated portion of the lesson, we explore a section of the Rio Grande watershed and channel in New Mexico using Google Earth imagery, river profiles, and graphic animations. We highlight features of the upland catchments, the river channel, and the Elephant Butte Reservoir. We then demonstrate how environmental factors (climate, geography, land use changes, reservoirs) impact the supply and movement of sediments for the Rio Grande and other rivers. The focus is on the three primary processes in sedimentation: generation, transport, and deposition. The lesson then addresses natural climate and weather influences along with some observed and projected trends associated with climate change.

The rapid expansion of commodity agriculture in tropical forest landscapes is a key driver of deforestation. To meet the growing demand from a more prosperous and expanding global population, it is imperative to develop sustainable commodity supply chains that support higher agricultural productivity, and that enable improved environmental, economic, and social outcomes. Interventions by community, market, and state actors can enhance the sustainability of supply chains by affecting where and how agricultural production occurs. These interventions—in the form of novel or moderated institutions and policies, incentives, or information—can influence producers directly or achieve their impacts indirectly by influencing consumer, retailer, and processor decisions.
This study used global datasets to document the trends in deforestation and commodity agriculture production to compare and explain the impacts of different types of supply chain interventions.

The first was to strengthen Jordan’s capacity to respond to the detrimental impacts of Climate Change expected to add a multiplying effect to current challenges in sectors like water and agriculture. The second was to strengthen Jordan’s global stewardship in addressing options to reduce emissions while achieving sound and sustainable developmental objectives especially in the various sectors of energy.PermalinkUganda has been regarded as a development success story due to its increasing economic growth and declining poverty. Nevertheless, the country’s economic dependence on agriculture makes it very sensitive to climate variability and change. Temperatures in Uganda have been steadily increasing and climate hazards such as floods and droughts have become more frequent and intense, a trend expected to continue. Ugandan smallholder farmers already know and apply various global best practices to reduce climate risks, but much remains to be done to improve these local responses. This report argues that ...PermalinkClimate-related hazards, including drought, floods, cyclones, sea-level rise and extreme temperatures, have enormous impact on the socio-economic development of a society. The frequency, magnitude and duration of damaging climate conditions are changing.

PermalinkFAO, 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. This annual flagship report by the Food and Agriculture Organization (FAO) reviews the economic and social rationale for agricultural investment, examines the causes of underinv ...PermalinkCrop 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 ...PermalinkThis edition focuses on the potato as a targeted disaster risk reduction effort in western Afghanistan. By helping farmers adapting how they handle the potatoes, it describes how the USAID program is enabling farmers to grow more food to last through the cold winter months and even have a chance to sell surplus produce when prices are favorable to them. It demonstrates that a more resilient livelihood means less vulnerability to weather-related and economic shocks.PermalinkAgriculture accounts for 30 per cent of global greenhouse gas emissions. How agriculture is practised, therefore, has significant potential for mitigating climate change, providing food security and improving the livelihoods of food producers worldwide. There is growing interest in the use of market governance mechanisms for tackling climate change by giving the financial incentives to make the required changes. The key messages emerging from this study are that economic measures have a vital part to play, but to be effective, emissions from food production and consumption must be addressed to ...PermalinkSince the Global Conference on Climate Change, Food Security and Agriculture held at the Hague in 2010, the concept of climate-smart agriculture (CSA) has gained increasing attention at international and national levels, with several countries initiating related activities. The objective of this paper is to highlight recent experiences with country-level implementation of CSA to identify some key lessons to incorporate in ongoing efforts to expand the use of the approach in developing countries. Section 1 describes the evolution of the concept of CSA since the Hague conference. Section 2 i ...PermalinkAgriculture 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 ...PermalinkWe explore the relationship between farming practice changes made by households coping with the huge demographic, economic, and ecological changes they have seen in the last 10 years and household food security. We examine whether households that have been introducing new practices, such as improved management of crops, soil, land, water, and livestock (e.g. cover crops, micro-catchments, ridges, rotations, improved pastures, and trees) and new technologies (e.g. improved seeds, shorter-cycle and drought-tolerant varieties) are more likely to be food secure than less innovative farming househo ...PermalinkSteduto 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.PermalinkThis report provides input into the discussions at the 2012 World Water Week in Stockholm and its special focus on water and food security. This report presents the latest thinking and new approaches to emerging and persistent challenges to achieve food security in the 21st century, including the use of early warning systems to bolster food security by reducing damages caused to agriculture by water scarcity and drought.
