Seguridad alimentaria, nutrición y erradicación del hambre CELAC 2025: elementos para el debate y la cooperación regionales

La región de América Latina y el Caribe ha mostrado una trayectoria exitosa en el proceso de erradicación del hambre y es la única región del mundo que redujo a la mitad tanto la proporción de personas que padecen hambre (meta establecida en los Objetivos de Desarrollo del Milenio) como el número absoluto de personas afectadas por el hambre (meta establecida en la Cumbre Mundial sobre la Alimentación, de 1996). El propósito de esta publicación es suministrar a los países de la región información actualizada y oportuna sobre el estado de la seguridad alimentaria y nutricional, el papel que tienen distintas áreas como la agricultura, el comercio agroalimentario y la gestión de recursos naturales en la erradicación del hambre y la posibilidad de enfrentar con éxito la doble carga de la malnutrición, en un contexto en que los efectos del cambio climático pueden amenazar los avances observados hasta el momento en América Latina y el Caribe. El Plan para la Seguridad Alimentaria, Nutrición y Erradicación del Hambre de la CELAC 2025 es una herramienta trascendental para el logro de los Objetivos de Desarrollo Sostenible de la Agenda 2030 para el Desarrollo Sostenible y, por ello, alienta a los países de América Latina y el Caribe a redoblar los esfuerzos para identificar las áreas clave de política que permitan acelerar y consolidar el proceso de erradicación del hambre y hacer frente a la doble carga de la malnutrición en la región, donde el sobrepeso y la obesidad se suman cada vez más a ese flagelo.

Food and nutrition security and the eradication of hunger CELAC 2025: Furthering discussion and regional cooperation

The region of Latin America and the Caribbean can boast a successful track record in the process of eradicating hunger: it is the only region in the world that has halved both the proportion of people who suffer from hunger (the target set in the Millennium Development Goals) and their absolute number (the target set at the World Food Summit of 1996). This publication aims to provide the region’s countries with up-todate and timely information on the status of food and nutrition security; on the role in eradicating hunger played by the different areas such as agriculture, agrifood trade and natural resources management; and on the possibility of successfully addressing the twin burden of malnutrition, in a context where the effects of climate change could threaten the progress achieved in Latin America and the Caribbean thus far. The CELAC Plan for Food and Nutrition Security and the Eradication of Hunger 2025 is a cross-cutting tool for achieving the Sustainable Development Goals of the 2030 Agenda for Sustainable Development; and it thus encourages the countries of Latin America and the Caribbean to redouble their efforts to identify key policy areas that will make it possible to speed up and consolidate the process of eradicating hunger and tackle the twin burden of malnutrition in the region, in which overweight and obesity are increasingly adding to that scourge.

European biorefineries:implications for land, trade and employment

Biorefineries are expected to play a major role in a future low carbon economy and substantial investments are being made to support this vision. However, it is important to consider the wider socio-economic impacts of such a transition. This paper quantifies the potential trade, employment and land impacts of economically viable European biorefinery options based on indigenous straw and wood feedstocks. It illustrates how there could be potential for 70-80 European biorefineries, but not hundreds. A single facility could generate tens of thousands of man-years of employment and employment creation per unit of feedstock is higher than for biomass power plants. However, contribution to national GDP is unlikely to exceed 1% in European member states, although contributions to national agricultural productivity may be more significant, particularly with straw feedstocks. There is also a risk that biorefinery development could result in reduced rates of straw incorporation into soil, raising concerns that economically rational decisions to sell rather than reincorporate straw could result in increased agricultural land-use or greenhouse gas emissions. © 2013.

Half-degree gridded nitrogen and phosphorus fertilizer use for global agriculture production during 1900-2013

In addition to enhance agricultural productivity, synthetic nitrogen (N) and phosphorous (P) fertilizer application in croplands dramatically altered global nutrient budget, water quality, greenhouse gas balance, and their feedbacks to the climate system. However, due to the lack of geospatial fertilizer input data, current Earth system/land surface modeling studies have to ignore or use over-simplified data (e.g., static, spatially uniform fertilizer use) to characterize agricultural N and P input over decadal or century-long period. We therefore develop a global time-series gridded data of annual synthetic N and P fertilizer use rate in croplands, matched with HYDE 3,2 historical land use maps, at a resolution of 0.5º latitude by longitude during 1900-2013. Our data indicate N and P fertilizer use rates increased by approximately 8 times and 3 times, respectively, since the year 1961, when IFA (International Fertilizer Industry Association) and FAO (Food and Agricultural Organization) survey of country-level fertilizer input were available. Considering cropland expansion, increase of total fertilizer consumption amount is even larger. Hotspots of agricultural N fertilizer use shifted from the U.S. and Western Europe in the 1960s to East Asia in the early 21st century. P fertilizer input show the similar pattern with additional hotspot in Brazil. We find a global increase of fertilizer N/P ratio by 0.8 g N/g P per decade (p< 0.05) during 1961-2013, which may have important global implication of human impacts on agroecosystem functions in the long run. Our data can serve as one of critical input drivers for regional and global assessment on agricultural productivity, crop yield, agriculture-derived greenhouse gas balance, global nutrient budget, land-to-aquatic nutrient loss, and ecosystem feedback to the climate system.

Land, Power and Technology : Essays on Political Economy and Historical Development

Land Ownership and Development: Evidence from Postwar Japan This paper analyzes the effect of land ownership on technology adoption and structural transformation. A large-scale land reform in postwar Japan enforced a large number of tenant farmers who were cultivating land to become owners of this land. I find that the municipalities which had many owner farmers after the land reform tended to experience a quick entry of new agricultural machines which became available after the reform. The adoption of the machines reduced the dependence on family labor, and led to a reallocation of labor from agriculture to industries and service sectors in urban centers when these sectors were growing. I also analyze the aggregate impact of labor reallocation on economic growth by using a simple growth model and micro data. I find that it increased GDP by about 12 percent of the GDP in 1974 during 1955-74. I also find a large and positive effect on agricultural productivity. Loyalty and Treason: Theory and Evidence from Japan's Land Reform A historically large-scale land reform in Japan after World War II enforced by the occupation forces redistributed a large area of farmlands to tenant farmers. The reform demolished hierarchical structures by weakening landlords' power in villages and towns. This paper investigates how the change in the social and economic structure of small communities affects electoral outcomes in the presence of clientelism. I find that there was a considerable decrease in the vote share of conservative parties in highly affected areas after the reform. I find the supporting evidence that the effect was driven by the fact that the tenant farmers who had obtained land exited from the long-term tenancy contract and became independent landowners. The effect was relatively persistent. Finally, I also find the surprising result that there was a decrease, rather than an increase, in turnout in these areas after the reform.  Geography and State Fragmentation We examine how geography affects the location of borders between sovereign states in Europe and surrounding areas from 1500 until today at the grid-cell level. This is motivated by an observation that the richest places in this region also have the highest historical border presence, suggesting a hitherto unexplored link between geography and modern development, working through state fragmentation. The raw correlations show that borders tend to be located on mountains, by rivers, closer to coasts, and in areas suitable for rainfed, but not irrigated, agriculture. Many of these patterns also hold with rigorous spatial controls. For example, cells with more rivers and more rugged terrain than their neighboring cells have higher border densities. However, the fragmenting effects of suitability for rainfed agriculture are reversed with such neighbor controls. Moreover, we find that borders are less likely to survive over time when they separate large states from small, but this size-difference effect is mitigated by, e.g., rugged terrain.

Climate Change or Urbanization? Impacts on a Traditional Coffee Production System in East Africa over the Last 80 Years

Global environmental changes (GEC) such as climate change (CC) and climate variability have serious impacts in the tropics, particularly in Africa. These are compounded by changes in land use/land cover, which in turn are driven mainly by economic and population growth, and urbanization. These factors create a feedback loop, which affects ecosystems and particularly ecosystem services, for example plant-insect interactions, and by consequence agricultural productivity. We studied effects of GEC at a local level, using a traditional coffee production area in greater Nairobi, Kenya. We chose coffee, the most valuable agricultural commodity worldwide, as it generates income for 100 million people, mainly in the developing world. Using the coffee berry borer, the most serious biotic threat to global coffee production, we show how environmental changes and different production systems (shaded and sun-grown coffee) can affect the crop. We combined detailed entomological assessments with historic climate records (from 1929-2011), and spatial and demographic data, to assess GEC's impact on coffee at a local scale. Additionally, we tested the utility of an adaptation strategy that is simple and easy to implement. Our results show that while interactions between CC and migration/urbanization, with its resultant landscape modifications, create a feedback loop whereby agroecosystems such as coffee are adversely affected, bio-diverse shaded coffee proved far more resilient and productive than coffee grown in monoculture, and was significantly less harmed by its insect pest. Thus, a relatively simple strategy such as shading coffee can tremendously improve resilience of agro-ecosystems, providing small-scale farmers in Africa with an easily implemented tool to safeguard their livelihoods in a changing climate.

Produtividade e qualidade de grãos de híbridos de canola cultivados em diferentes épocas no sudoeste do Paraná

Canola is the third most important oilseed in global agribusiness. Used in several market segments, its cultivation in Brazil began in the 70s The growth of canola cultivation aimed at producing beans intended for oil extraction can provide high economic efficiency of farms, the choice of the time correct for sowing is essential for this purpose is achieved. Objective of this study was to evaluate the performance of canola hybrids (Hyola 61, Hyola 76, Hyola 411, 433 and Hyola Hyola 571) evaluated in six sowing dates started on 09/03 (1 time) 06/04 (2 times ), 04/05 (3 times), 01/06 (4 times), 29/06 (5 times) and 26/07 (6 times). The experiments were conducted at the Experimental Station of the Federal Technological University of Paraná - UTFPR, Campus Dois Vizinhos. The field experiment was arranged in a randomized block design with split plots in three replications in two years (2013 and 2014 crop). Evaluated the agronomic characteristics as the number of days between emergence and flowering, number of days duration of flowering, number of days between emergency and physiological maturity, average plant height, plant lodging, grain yield, weight a thousand grains, crude protein content in grain and ether extract in the grains. There were significant differences between the effects of the six sowing dates in all variables, including hybrids and years. The study was able to show that it is possible to grow canola in the Southwest of Paraná. Being the first times more responsive sowing and Hyola 411 and Hyola 433 hybrid proved the most suitable among the variables observed.
