Integrated approach to address the water challenge
There is no silver bullet—no one answer to addressing the global water challenge. But an integrated approach
using the technologies outlined here and tailored to the local conditions, crops, and farmers can maximize water use efficiency. As a result, farmers will not only produce more food but also become stewards of the land, protecting against rain run-off, soil erosion, water stress on plants, flooding, and desertification of arable land. Desertification, which occurs in arid areas from various factors, including climate variation and human activities, degrades land to the point it can no longer grow crops.
To better manage the competing demands for water, agricultural policies will have to make water efficiency a priority. This will require investment in research to develop innovative water-efficient technologies in addition to drought tolerant seeds, new crop protection products, and optimized irrigation systems for specific crops. But the best and most innovative technology is useless if farmers cannot afford it, see no advantage to it, or do not understand it.Water efficiency measures using existing agricultural technology can sustainable increase net water availability, at a reasonable cost. In comparison, trying to increase water supply often requires energy-intensive measures such as desalination, which are vastly more expensive than the efficiency measures outlined.
Enabling individuals and communities to understand their options for managing water, to choose from these options, and to take responsibility for their choices could positively alter the way the world uses its limited water resources.Therefore, a key component of policy-making will have to include infrastructure for knowledge sharing and access to technology. Governments, NGOs, and public-private partnerships should facilitate implementing technology on the farm where better water management is critical for food production and the environment. This includes access to affordable credit and financial risk-management mechanisms, such as insurance for weather-related crop losses. Already the benefits of this model can be seen in partnerships between developed country governments, international organizations, and private companies which are helping small farms with access to finance, guaranteed markets, technical assistance, and insurance.
