Sustainable intensification depends on two parts:
- compensate the losses of nutrients (due to uptake of the plants and leaching) by adding these nutrients at the begin or during the cultivation
- maintain a good soil structure by supplying a part of these nutrients as organic (compost or manure)
- optimum utilization of inputs
- mobilization of the natural agroecological processes
- reduction in the use of any input, process, or technology that has a detrimental impact on environment.
It could be possible naturally by enrichment of soil nutrition through symbiotic nitrogen fixation by legume crops
Intensive agriculture require the use of other methods like hydroponics so that the farmer ca use space beyond land. Use crop and livestock farming to have more than one type of product
Dear Nawab,
I think that an intensification of agriculture cannot be sustainable either because the technology is unaffordable to a majority of farmers, or because the technology affects negatively the environment while depleting further the natural resource base. Many scientists predicate that an intensification of agriculture is necessary to feed a population of 10 billion people within the next 30 years however, the world is producing already sufficient food for 19 billion (check the work of Altieri et al. about this). Humanity should instead find ways to give better access of food to people while reducing food waste.
by increasing soil fertility and health through managing it by adding organic and naturally friendly inputs at the soil.
Existem algumas vertentes de agricultura, dois modelos principais são: o cultivo orgânico e a agricutura convencional.
Enquanto a agricultura convencional, aonde a produtividade é intensificada, a rentabilidade maximizada, as perdas minimizadas, com uma logistica apurada, precisamos de um Sistema de cultivo inteligente e de precisão.
Por outro lado, nos últimos anos, vem crescendo a agricultura orgânica, com produtos mais sudáveis, com produção sustentável, com uma logistica de distribuição de produtos mais regionalizada.
Maximizing inputs on a limited piece of land with a specific tillage system such as rip lines or planting basins. This may also involve use of fertilizers in combination with organic manure or intercropping of cereals with legumes
Kindly check the following link that includes a set of priority practices for sustainable intensification that provides policy makers, researchers, and farmers with a starting point for thinking about how to implement sustainable intensification in practice:
https://www.agri-tech-e.co.uk/what-agricultural-practices-could-deliver-sustainable-intensification/
I think only using the results of practical experiences can be useful.
Best and most sustainable way is to use agroecological intensification to reach sustainable intensification. http://www.fao.org/cfs/cfs-hlpe/hlpe-reports/en/ https://doi.org/10.1016/j.foodpol.2019.101815
Sustainable and Intensification are incompatible in my opinion. Instead of intensifying we should try to optimize levels of agricultural production. An application of the industrial model in agriculture remains and always will remain extractive and unsustainable. The recent concepts to justify a sustainable intensification of agriculture such as: smart farming, precision agriculture, etc., are only propaganda terms invented by the agroindustry to give a "green" image to the most disturbing and resource-demanding human activity, which is agriculture.
Dear Dr.Bruno Borsari, thank you so much for your interesting compliment.
Hope usefull

Diversified crop cultivation through crop rotation in the cropping pattern, then the intensification of agriculture will be sustainable. For example, have to cultivate Rice-Wheat-Mungbean is one of the best options to improve the sustainable intensification of agriculture.
Albeit a bit radical one, I appreciate prof. Borsari's answer. I agree with him about considering "sustainable intensification" of agriculture as an oxymoron, largely driven by global agri-business firms. Being an Italian scientist myself I'd like to get in touch with him in the future.
