How diverse are farming systems on the Eastern Gangetic Plains of South Asia? A multi-metric and multi-country assessment

Brendan Brown Pragya Timsina Emma Karki (2023, [Artículo])

While crop diversification has many benefits and is a stated government objective across the Eastern Gangetic Plains (EGP) of South Asia, the complexity of assessment has led to a rather limited understanding on the progress towards, and status of, smallholder crop diversification. Most studies focus on specific commodities or report as part of a singular index, use outdated secondary data, or implement highly localized studies, leading to broad generalisations and a lack of regional comparison. We collected representative primary data with more than 5000 households in 55 communities in Eastern Nepal, West Bengal (India) and Northwest Bangladesh to explore seasonally based diversification experiences and applied novel metrics to understand the nuanced status of farm diversification. While 66 crops were commercially grown across the region, only five crops and three crop families were widely grown (Poaceae, Malvaceae, and Brassicaceae). Non-cereal diversification across the region was limited (1.5 crops per household), though regional differentiation were evident particularly relating to livestock and off-farm activities, highlighting the importance of cross border studies. In terms of farmer's largest commercial plots, 20% of systems contained only rice, and 57% contained only rice/wheat/maize, with substantial regional diversity present. This raises concerns regarding the extent of commercially oriented high value and non-cereal diversification, alongside opportunities for diversification in the under-diversified pre-monsoon and monsoon seasons. Future promotional efforts may need to focus particularly on legumes to ensure the future sustainability and viability of farming systems.

Natural disasters and economic growth: a synthesis of empirical evidence

Fernando Antonio Ignacio González (2023, [Artículo, Artículo])

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.

Dispositivo de control para la aplicación del riego intermitente

ALVARO ALBERTO ALDAMA RODRIGUEZ Polioptro Martinez-Austria (1991, [Artículo])

El riego intermitente es un nuevo método de aplicación del agua a nivel parcelario para sistemas por gravedad, melgas o surcos, que en determinadas condiciones permite incrementar notablemente la eficiencia en el uso del agua, observándose también mejores perfiles de humedad en el suelo. Por otra parte, la indispensable intermitencia en la aplicación del agua debe ser producida por algún sistema automático. Hoy en día existen en el mercado varios tipos de válvulas electrónicas, cuyo uso es una opción. Sin embargo, hay otras de menor costo y mejor adaptadas a las condiciones generales de México. En este artículo se abordan los principios y criterios de diseño de un dispositivo de descargas intermitentes sencillo y de bajo costo, que puede ser construido y modificado por los agricultores según sus necesidades. Está diseñado para funcionar en surcos cortos, como los que se encuentran en nuestro país. Se ilustran los principios generales de su funcionamiento y, para aquellos interesados, se muestra la derivación de las ecuaciones generales correspondientes. Se presentan los procedimientos y resultados de su validación en el laboratorio y en el campo. De estas experiencias se derivan criterios y recomendaciones para su diseño y operación.
