Anne M. Hansen DANGELO ANTONIO SANDOVAL CHACON (2019, [Documento de trabajo])

El objetivo del proyecto es evaluar experimentalmente y mediante modelación, las cargas externa (CE) e interna (CI) de carbono (C) en un cuerpo de agua. El sitio seleccionado para la realización de esta investigación, es la presa Valle de Bravo. La presa forma parte del sistema Cutzamala que suministra 345 Mm3 de agua potable para uso residencial e industrial tanto a la Ciudad como al Estado de México.

El objetivo de este estudio es realizar una estimación preliminar de los gases de efecto invernadero generados por los habitantes de las cabeceras municipales que conforman la cuenca del río Apatlaco, en el estado de Morelos para el periodo 2015-2017, para establecer una línea base. Los diez municipios que conforman la cuenca son: Huitzilac, Cuernavaca, Jiutepec, Temixco, Emiliano Zapata, Xochitepec, Jojutla, Tlaltizapán, Puente de Ixtla y Zacatepec.

Potential impacts of Ukraine-Russia armed conflict on global wheat food security: A quantitative exploration

Khondoker Mottaleb Gideon Kruseman Sieglinde Snapp (2022, [Artículo])

Violent conflict is a major cause of acute food crises. In 2021, at least 155 million people in 10 countries were severely food insecure and eight of those countries were experiencing armed conflict. On February 24, 2022, an armed conflict between Russian Federation (Russia) and Ukraine escalated. As Russia and Ukraine are major wheat exporters, this will aggravate the already precarious food security situation in many developing countries by disrupting wheat production and export and by accelerating price hikes in import-dependent developing countries. This study examines the potential impacts of this ongoing armed conflict between Russia and Ukraine on wheat price, consumption, and calorie intake from wheat. In doing so, it applies the conditional mixed process estimation procedure using information collected from 163 countries and territories for the years 2016–2019 from online database of the Food and Agriculture Organization of the United Nations (FAO). The study shows that, on average, a 1% decrease in the global wheat trade could increase the producers' price of wheat by 1.1%, and a 1% increase in the producers' price could reduce the yearly per capita wheat consumption by 0.59%, daily calorie intake by 0.54% and protein intake by 0.64% in the sampled countries. Based on this, the study demonstrates that a 50% reduction in wheat exports by Russia and Ukraine could increase the producers’ price of wheat by 15%, which would induce a reduction in wheat consumption and dietary energy intake by at least 8%. Since wheat export has reduced from both Russia and Ukraine, to avoid a food crisis in developing countries, policies are suggested, including near term improvement of domestic wheat production by promoting improved agronomic practices to close yield gaps to meet a substantial portion of wheat self-sufficiency goals. In the long run, countries in Africa, East Asia and South America can explore expanding wheat into new land area. International donor agencies can play a key role in supporting the ongoing wheat research and development activities.

Con el propósito de evaluar la contribución de los embalses del país en la emisión de gases de efecto invernadero, se seleccionó al embalse Valle de Bravo, en el Estado de México como caso de estudio. Se realizó una caracterización detallada de la cuenca Valle de Bravo considerando a los elementos del medio biofísico con mayor impacto en el proceso de erosión y de la producción de sedimentos en la cuenca como son geología, geomorfología, suelos, uso del suelo, precipitación, temperatura, hidrología principalmente, y con ello establecer la situación actual de la misma en lo relativo a su medio natural. Asimismo se realizó la caracterización de la calidad del agua en la columna de agua del embalse.

Agricultural lime value chain efficiency for reducing soil acidity in Ethiopia

Moti Jaleta (2023, [Artículo])

Soil acidity is challenging agricultural production in Ethiopia. Above 43% of the farmland is under soil acidity problem and it leads to low crop yields and production losses. Ag-lime is widely considered as an effective remedy for amending soil acidity. This study assesses the current structure of ag-lime value chain and its functionality focusing on central parts of Ethiopia where lime is produced and channeled to acidity affected areas. The study uses Ethiopia as a case study and applies qualitative methods such as key informant interviews and focus group discussions to collect data from different actors in the ag-lime value chain. Key findings indicate that both public and private ag-lime producing factories are operating below their capacity. Due to limited enabling environments, the engagement of private sector in ag-lime value chain is minimal. In addition, farmers have a good awareness of soil acidity problem on their farms, and its causes and mitigation strategies in all regions. However, the adoption of ag-lime by smallholders was minimal. Overall, the current structure of the ag-lime value chain appears fragmented and needs improvement. Addressing soil acidity challenge through efficient ag-lime value chain could narrow lime supply-demand mismatches and increase widespread adoption by farmers to enhance crop productivity and food security in acidity-prone areas of the country.
