T.S. Jayne, Jordan Chamberlin, Milu Muyanga
Center on Food Security and the Environment, 2012

Despite the fact that sub-Saharan Africa in 2012 contains much of the world’s unutilized and underutilized arable land, a significant and growing share of Africa’s farm households live in densely populated areas.

Climatic Change, 2011

Perennial crops are among the most valuable of California’s diverse agricultural products. They are also potentially the most influenced by information on future climate, since individual plants are commonly grown for more than 30 years. This study evaluated the impacts of future climate changes on the 20 most valuable perennial crops in California, using a combination of statistical crop models and downscaled climate model projections.

This paper examines different paths and challenges in stages of agricultural transformation in two Asian countries. It contrasts their respective mechanisms of labor transfer from the agriculture sector to non- agriculture sectors and the up-skilling of the agricultural labor force in the process of an agricultural transformation. The paper describes this as a critical contribution from agriculture to economic growth.

Dissertation

Kaitlin Shilling
2011

Climate change will lead to massive conflicts, according to claims of such prominent sources as Sir Nicholas Stern and the US National Security Agency - claims repeated by the media. Efforts to tease a specific climate change signal from historical records of civil conflict have proved inconclusive, however: they postulate that farmers will become fighters when resources become critically scarce; but they have been unable to illuminate what specific mechanisms may be involved.

Promotion of smallholder irrigation is cited as a strategy for enhancing income generation and food security for sub-Saharan Africa’s poor farmers, but what makes this technology a successful poverty alleviation tool? In the short run, the technology should pave the way for increased consumption, asset accumulation, and reduced persistent poverty among users. Over the longer run, it should lead to institutional feedbacks that support sustained economic development and nutritional improvements.

International Labour Organization, 2011

This volume examines the experiences of 21 developed and developing countries in adjusting their training provision to meet the new demands of a greener economy. It shows that skills development is critical to unlocking the employment potential of green growth, yet skills shortages are becoming an obstacle in realizing this potential. The report recommends that countries devise strategies based on well-informed policy decisions, social dialogue, and coordination among ministries and between employers and training providers.

World leaders are focused on agricultural supply data, insurance schemes and speculation as they try to quell volatility in global food markets. They should also turn their attention to perhaps the leading cause of price instability: U.S. ethanol policy.

Sugar and ethanol production are key components of Brazil's rural development and energy strategies, yet in recent years sugar production has been widely criticized for its environmental and labor practices. This study examines the relationship between rural development and sugarcane, ethanol, and cattle production in the state of São Paulo.

Knowledge systems—networks of linked actors, organizations, and objects that perform a number of knowledge-related functions that link knowledge and know how with action—have played a key role in fostering agricultural development over the last 50 years. We examine the evolution of the knowledge system of the Yaqui Valley, Mexico, a region often described as the home of the green revolution for wheat, tracing changes in the functions of critical knowledge system participants, information flows, and research priorities.

One way of understanding how climate change is likely to affect global food production and food security is to better understand the recent past. That is, how have changes al-ready influenced agricultural activities and production? For example, considerable debate has taken place on whether future impacts in agriculture will be driven mainly by rising temperatures, or if instead precipitation changes are the main concern. The answer to this would influence strategies to adapt, such as investing in heat tolerance versus waiting for better rainfall projections.

Efforts to anticipate how climate change will affect future food availability can benefit from understanding the impacts of changes to date. Here we show that in the cropping regions and growing seasons of most countries, with the important exception of the United States, temperature trends for 1980-2008 exceeded one standard deviation of historic year-to-year variability. Models that link yields of the four largest commodity crops to weather indicate that global maize and wheat production declined by 3.8% and 5.5%, respectively, compared to a counter-factual without climate trends.

Sub-Saharan Africa (SSA) is home to two-thirds of the world’s ultra-poor today. This paper offers current thinking on the structural causes of the spatially concentrated, persistent ultra-poverty that has plagued Africa for a generation and some key entry points for facilitating Africans’ escape from persistent ultra-poverty.

Food Security, 2011

The challenges of reducing global hunger and poverty are different today than they were 30 years ago. Current challenges include price volatility associated with increased integration of food, energy, and finance markets; the steady progression of climate change; poorly defined land institutions; and a failure to break vicious cycles of malnutrition and infectious disease.

The increasing global demand for biofuels will require conversion of conventional agricultural or natural ecosystems. Expanding biofuel production into areas now used for agriculture reduces the need to clear natural ecosystems, leading to indirect climate benefits through reduced greenhouse-gas emissions and faster payback of carbon debts. Biofuel expansion may also cause direct, local climate changes by altering surface albedo and evapotranspiration, but these effects have been poorly documented.

Improved understanding of the influence of climate on agricultural production is needed to cope with expected changes in temperature and precipitation, and an increasing number of undernourished people in food insecure regions. Many studies have shown the importance of seasonal climatic means in explaining crop yields. However, climate variability is expected to increase in some regions and have significant consequences on food production beyond the impacts of changes in climatic means.

Nature Climate Change, 2011

New approaches are needed to accelerate understanding of climate impacts on crop yields, particularly in tropical regions. Past studies have relied mainly on crop-simulation models, or statistical analyses based on reported harvest data, each with considerable uncertainties and limited applicability to tropical systems. However, a wealth of historical crop-trial data exists in the tropics that has been previously untapped for climate research.

Biomass-derived energy offers the potential to increase energy security while mitigating anthropogenic climate change, but a successful path toward increased production requires a thorough accounting of costs and benefits. Until recently, the efficacy of biomass-derived energy has focused primarily on biogeochemical consequences.

Marine aquaculture is expanding rapidly without reliable quantification of effluents. The present study focuses on understanding the transport of dissolved wastes from aquaculture pens in near-coastal environments using the hydrodynamics code SUNTANS (Stanford Unstructured Nonhydrostatic Terrain-following Adaptive Navier-Stokes Simulator), which employs unstructured grids to compute flows in the coastal ocean at very high resolution.
