Anticipatory versus post-shock transfers: Conceptual analysis por de Brauw, Alan, Bloem, Jeffrey R.

“…Climate shocks are becoming increasingly prevalent because of climate change (IPCC, 2023). Moreover, these climate shocks have more potential to negatively affect populations of low- and middle-income countries, as these populations are more likely to be employed in or around agriculture for income generation, which is particularly vulnerable to climate change (Gitz et al., 2016; Clarke et al., 2022). …”

A bottom-up framework for assessing greenhouse gas emissions and mitigation potential in food systems por Kakai, L.F., Noufa, C.K., Sapkota, T.B., Corbeels, M., Choptiany, J.M.H.

“…To enhance transparency and decision relevance, it embeds explicit uncertainty characterization consistent with IPCC good practice principles. Overall, this framework supports national reporting, subnational climate planning, and the development of credible, implementable mitigation pathways aligned with NDCs and long-term low-emission development strategies.…”

Rice and global climate change por Wassmann, Reiner, Nelson, Gerald C., Peng SB, Sumfleth K, Jagadish, Krishna S.V., Hosen Y, Rosegrant, Mark W.

“…The effects of these changing conditions on agriculture are already being seen, yet there are still considerable gaps in our knowledge of how agricultural systems will be affected directly or indirectly by the changing climate, and what implications these changes will have for rural livelihoods (IPCC 2007). Climate change gives an additional burden to the world’s agricultural and natural resource systems that must already cope with the growing food demand driven by population growth and higher incomes in developing countries. …”

Livestock and greenhouse gas emissions: The importance of getting the numbers right por Herrero, Mario, Gerber, Pierre J., Vellinga, Theun V., Garnett, Tara, Leip, A., Opio, C., Westhoek, H.J., Thornton, Philip K., Olesen, Jørgen E., Hutchings, N., Montgomery, H., Soussana, J.F., Steinfeld, H., McAllister, T.A.

“…In reality, estimates of international scientific organizations such as the International Governmental Panel on Climate Change (IPCC) and the Food and Agriculture Organization (FAO) are in close agreement, with variation mainly arising on how GHG emissions are allocated to land use and land use change. …”

Impact of climate change on water resources and potential adaptations for Indian agriculture por Sharma, Bharat R.

“…Although there is a lack of adequate scientific evidence on regional scales, a number of recent observational and modelling studies do suggest that the climate is changing. According to IPCC, the most significant consequences of climate change will be its impact on the hydrologic cycle, as already experienced in many parts of the world including India. …”

Carbono orgánico del suelo en tres sistemas de producción ganadera del Valle del Patía – Colombia por Morales Velasco, Sandra, Cotacio, Elver Julián, Vivas Quila, Nelson José, Gutiérrez Solís, Jhon Freddy, Albán López, Noé, Peters, Michael, Hincapié Carvajal, Belisario

“…Pero las reservas se pueden perder dependiendo del uso y manejo; estimándose que los ecosistemas agrícolas han liberado hasta un 75 % del COS hacia la atmosfera generando impactos negativos (desertización, clima, baja productividad) sobre la tierra. De acuerdo al IPCC (2006) hay prácticas que favorecen la acumulación de COS (rotación de cultivos, incremento de la materia orgánica, mulching, entre otros) por esta razón y con el propósito de establecer estrategias de manejo que contribuyan a la sostenibilidad de la producción ganadera en el Valle del Patía, se muestrearon suelos de tres sistemas de acuerdo al tipo de pastura y se analizó el contenido de carbono orgánico (Walkley y Black), forraje establecido y el manejo realizado en cada uno de ellos.…”
