This report looks at farm management practices with green growth potential, from farmer-led innovations (such as those directly linked to soil and water, Integrated Pest Management, organic farming) to science-led technologies (such as biotechnology and precision agriculture). Global food demand can only be met in a sustainable way if new forms of agricultural production and innovative technologies can be unlocked to increase the productivity, stability, and resilience of production systems with goals beyond just raising yields, including saving water and energy, reducing risk, improving product quality, protecting the environment and climate change mitigation.
Climate change is expected to increase the frequency and magnitude of extreme weather events, notably of droughts and floods to which the agriculture sector is particularly exposed. While agricultural productivity growth and policy development have allowed to better cope with these risks and reduce overall impacts on the sector and commodity markets, there is substantial room to improve policy responses and co-ordinate across policy domains, including with respect to water rights and allocation, weather and hydrological information, innovation and education, and insurance and compensation schemes. Indeed, drought and flood risks are likely to become a major policy concern as increasing population will increase the demand for food, feed, fibre, and energy, not to mention the competition for water resources, and urbanisation will increase the demand for flood protection and mitigation, raising the issue of the allocation of flood risks across sectors and areas.
Les eaux souterraines ont généré de larges bénéfices pour l’agriculture irriguée dans les zones semi-arides des pays de l’OCDE, mais l’utilisation intensive de ces eaux au-delà de leur taux de recharge dans certaines régions a conduit à l’abaissement du niveau des nappes phréatiques et engendré des externalités environnementales négatives. Ce rapport présente une caractérisation de la diversité des systèmes hydrogéologiques, analyse les politiques des pays de l’OCDE et propose une panoplie de recommandations permettant aux eaux souterraines de contribuer de manière durable à la production agricole et de contribuer à son adaptation au changement climatique.
Drought in California has been in the headlines frequently these last three years, with startling pictures of empty reservoirs, rivers and canals, wildfires, disappearing snowpack and dry earth. Yet these dramatic effects have not stopped the agricultural sector from growing.
