The Challenge of Agricultural Sustainability for Asia and Europe

摘要

It is expected that climate change (CC), growing population, increasing urbanization and improving living standards are amongst the major drivers influencing future agricultural development needs. Under conventional agricultural systems, the main sources of growth in crop production are well known. Beyond suffering its consequences, agriculture has been shown to act as a driver of CC, primarily through the production and release of about 15% of the atmospheric greenhouse gases but also by altering the resilience of the agro-ecosystems. The main criterion for the production systems called conservation agriculture (CA) is the provision of an optimum environment in the root-zone to maximum possible depth. Under CA the water-holding capacity of the soil increases, and water losses are reduced. CA combined with other complementary techniques can also help reduce the emissions for methane and nitrous oxides and at the same time it can improve rural and socio-economic development.
