América Latina y el Caribe (ALC) se caracteriza por aplicar una estrategia de desarrollo que depende de manera notable de la explotación de sus recursos naturales. Debido a que la población de la región aumenta de forma sistemática, la presión sobre los recursos naturales ha tenido un incremento marcado.
Nicaragua is the largest country in Central America, and agriculture is one of the engines of economic and social development. The agricultural sector contributes 16.1 percent of the Gross Domestic Product (GDP), 33 percent of formal employment and the food security of the population. There are 260 000 producers involved in agricultural production.
Nicaragua es el país más grande de América Central, y la agricultura es uno de los motores del desarrollo económico y social. El sector agrícola aporta el 16.1 por ciento del producto interno bruto (PIB), el 33 por ciento del empleo formal y la seguridad alimentaria de la población. Alrededor de la producción agropecuaria se integran 260 000 productores.
Local stakeholders and agricultural producers in Latin America have limited access to agroclimatic information and, when they do gain access to it, they have difficulty translating it into understandable and actionable knowledge. While climate services are recognized as contributing to bridging the gap between the generation of climate information and its use by stakeholders, their provision and use in Latin America still represents critical challenge.
Actores locales y productores agropecuarios en Latinoamérica tienen acceso limitado a la información agroclimática y, cuando logran acceder a ella, tienen dificultades para traducirla en conocimiento procesable y accionable. Si bien los servicios climáticos son reconocidos por contribuir a cerrar la brecha entre la generación de información climática y su uso por parte de las partes interesadas, su provisión y uso en Latinoamérica aún representa un desafío crítico.
The determination of bunch features that are relevant for bunch weight estimation is an important step in automatic vineyard yield estimation using image analysis. The conversion of 2D image features into mass can be highly dependent on grapevine cultivar, as the bunch morphology varies greatly. This paper aims to explore the relationships between bunch weight and bunch features obtained from image analysis considering a multicultivar approach.
Ornamental plants are constantly being improved by new technologies and cultivation systems to provide new, high-quality plant material for one of the most demanding markets in the horticulture sector. In addition, the ornamental production sector faces several challenges, such as an increase in costs of production, new and old pests and diseases, climate change and the need to adapt to environmental stresses, the need for conservation and environmental protection, and competition with other food and energy crops in terms of areas and natural resources.
Women in agriculture are far from the end of poverty, zero hunger, quality education, and gender equality — some of the sustainable development goals that can be significantly improved if we achieve greater participation and better working conditions for women in agriculture.
The application of ubiquitous computing has increased in recent years, especially due to the development of technologies such as mobile computing, more accurate sensors, and specific protocols for the Internet of Things (IoT). One of the trends in this area of research is the use of context awareness. In agriculture, the context involves the environment, for example, the conditions found inside a greenhouse.
The impact of global warming on crop growth periods and yields has been evaluated by using crop models, which need to provide various kinds of input datasets and estimate numerous parameters before simulation. Direct studies on the changes of climatic factors on the observed crop growth and yield could provide a more simple and intuitive way for assessing the impact of climate change on crop production.
