Natural Disasters and Economic Growth: a synthesis of empirical evidence

Fernando Antonio Ignacio González (2021)

Natural disasters pose a serious threat globally and, in the future, their frequency and severity are expected to increase due to climate change. Empirical evidence has reported conflicting results in terms of the impact of disasters on economic growth. In this context, the present work seeks to synthesize the recent empirical evidence related to this topic. More than 650 estimates, from studies published in the last five years (2015-2020), are used. Meta-analysis and meta-regression techniques are employed. The review includes three sources (Scopus, Science Direct, and Google Scholar). The results identified the existence of a negative and significant combined effect (-0.015). Developing countries are especially vulnerable to disasters. The negative impact is greater for disasters that occurred in the last decade -in relation to previous disasters-. These findings constitute a call for attention in favor of mitigation and adaptation policies.

Effect of an Exogenous Phytase on Growth Performance in Growing Holstein Calves

GERMAN BUENDIA RODRIGUEZ SERGIO SEGUNDO GONZALEZ MUÑOZ NORA IDOLINA ORTEGA ALVAREZ Patricia Aceves MARIA TERESA DEL SOCORRO MONTOYA FLORES Isaac Almaraz-Buendía JOSE ARMANDO PARTIDA DE LA PEÑA Abdelfattah Zeidan Mohamed Salem (2014)

The aim of this study was to evaluate the effect on the productive performance, apparent digestibility of DM, serum phosphorus and phosphorus balance in Holstein calves which received a high concentrate diet with different doses of exogenous phytase for a period of 60d. The experiment was conducted with a completely randomized design with three treatments of eight calves each, the treatment included dietary supplementation of exogenous phytase at 0, 12 and 24 g/ton. Phytase inclusion increased (P<0.05) average daily gain when phytase was supplemented at 24 (850g) as compared to 0 (816g) or 12 (809g) g/ton. However, it had no effect (P>0.05) on DM intake, feed conversion and DM digestibility. Adding phytase in the diet decreased phosphorus excretion in faeces (P<0.05) showing a significant linear increase with increasing level of supplementation (the values being 9.96, 9.14 and 8.13 g/d) which, in turn, increased the P retention (4.69, 5.37 and 6.45 g/d, resectively, for the three groups). In conclusion, supplementation of phytase could improve the growth performance of calves without any discernible effects on feed intake or digestibility of nutrients.

Acumulación de forraje, composición morfológica e intercepción luminosa en trigos (Triticum sp.)

CLAUDIA YANET WILSON GARCIA NELSON ERIK LOPEZ ZERON MARIA ESTHER ORTEGA CERRILLA MARIA MAGDALENA CROSBY GALVAN ADELAIDO RAFAEL ROJAS GARCIA ALFONSO HERNANDEZ GARAY (2018)

The objectives of the study were to perform the fodder accumulation curves and morphological components and light

interception to determine the optimal moment of cutting for green fodder of three lines and one wheat variety (Triticum sp.). Harvests were performed at intervals of 7 d, 43 days after sowing (DAS). In each harvest the average height of 20 plants was recorded, the intercepted radiation (IR), dry matter accumulation, morphological composition, and leaf area index (LAI). The sampling unit was a square of 0.45 m2.

Capital accumulation, economic growth and the balance-of-payments constraint: The case of Mexico, 1951-2014

Ignacio Perrotini Juan Alberto Vázquez-Muñoz Isabel Angoa Pérez (2021)

After a critical assessment of both Thirlwall’s long-run growth model and Clavijo’s and Ros’s (2015) model where capital accumulation determines output growth, this paper displays an alternative model in which capital accumulation and the growth rate of capital productivity determine the long-run growth rate of output which is consistent with a constant position of the balance of payments as a percentage of GDP. Then, the latter is applied to inquire the causes accounting for Mexico’s low economic growth rate during 1982-2014. We conclude, on empirical grounds, that the sharp decline in the internal demand for domestic goods and both the rates of net capital accumulation and productivity played a major role in the slowdown of the Mexican economy. The income elasticities of the demand for exports and imports also played a role, albeit to a lesser extent.

Growth, chlorophyll fluorescence and gas exchange of pepper (Capsicum chinense Jacq.) plants in response to uptake and partitioning of nutrients

ROCIO ELIZABETH MENESES LAZO RENE GARRUÑA HERNANDEZ Ileana de la Caridad Echevarría Machado CARLOS JUAN ALVARADO LOPEZ EDUARDO VILLANUEVA COUOH JOSE QUINATZIN GARCIA MALDONADO Jairo Cristóbal Alejo (2020)

Habanero pepper (Capsicum chinense Jacq.) does not have a specific fertilization. Therefore, the aim of this study was to evaluate growth, photosynthesis and accumulation of macro and micronutrients of habanero pepper plants. Plants were established in nutrient film technique (NFT) hydroponic systems. Two universal balanced solutions (Steiner and Hoagland) were compared versus a conventional solution (control: Soria solution). The concentration of macro and micronutrients in roots, stems, and leaves, photosynthetic activity of plants, total nitrate, amino acid and protein contents, and growth parameters were evaluated. According to the results, concentrations of K, Mg, Ca, Cu and Zn in plant tissues were higher in the Steiner and Hoagland treatments than control. In addition, the Steiner and Hoagland treatments increased the maximum photosynthetic rate (Amax) (81% and 80% respectively), light-saturated CO2 assimilation rate (Asat) (3.8-fold and 3-fold, respectively) and maximum catalytic activities of Rubisco (Vcmax) (51% and 30% respectively) with respect to the control. Hoagland treatment increased total nitrate content (3.66 mg g-1 FW), but Steiner treatment increased amino acids in leaves (169.97 mg g-1 FW) and control increased total proteins (1.49 mg g-1 FW). Steiner and Hoagland solutions significantly increased plant height (59% and 41% respectively), leaf area (1.26-fold and 1.02-fold, respectively), and total dry mass (80% and 69% respectively) with respect to the control solution. The results suggest that Steiner and Hoagland nutrient solutions provided nutrients that improve growth and photosynthetic activity. Moreover, total nitrate, amino acid and protein accumulation depend on the N source employed in nutrient solutions.

Active telomerase during leaf growth and increase of age in plants from Agave tequilana var. Azul

Zamaria Yoselín de la Torre Espinosa FELIPE ALONSO BARREDO POOL Enrique Castaño de la Serna Lorenzo Felipe Sánchez Teyer (2020)

In plants, previous studies show that telomerase activity contributes to the maintenance of telomeric length for the proper development of organs and tissues. In this work, we investigated telomerase activity in A. tequilana during several years of cultivation. We found that during growth of the leaf there are two crucial phases: (1) the onset of cell elongation in 3 years and (2) differentiation of vascular bundles in 6 years. This coincides with the ages where the highest telomerase activity is seen. Therefore indicates that telomerase is associated with cellular activities such as; elongation, division, and cell differentiation. Likewise, we detected high activity during the period of vegetative growth, indicating that telomerase also contributes to telomeric maintenance on the leaf in A. tequilana.
