How can farmers improve water use?

Farmers’ knowledge can play a significant role in increasing water-use efficiency, which directly influences the agricultural water management schemes. Farmers should be aware of technologies that help to manage the water efficiently and to optimise the crop production without harming the environment. For different crop types, different amounts of water are required. Farmers should also be aware of the requirement of the water for various crop types. Finally, there is strong need of developing detailed guidelines in the form of booklets in accordance with farmers’ perspectives and requirements for agricultural water management ( Hill and Allen, 1996 ). The guidelines should be simple and understandable for high, medium and low-input farmers.


What is consumptive irrigation water?

The consumptive use of irrigation water, defined as the water that is no longer available for use because it evaporated, transpired, or incorporated into crops, is transferred to the atmosphere as ET, and therefore, the spatial and temporal quantification of ET is essential in agricultural water management, at both field and district scales.


How can agriculture help the economy?

Focused investments in agricultural sector can leverage broader socioeconomic development, especially in resource-poor economies highly dependent on agriculture. Research demonstrates that investments in smallholder agriculture can serve as a key pathway to reducing rural poverty, generating economic growth, and supporting food security needs. As the potential to expand irrigated agricultural land is limited globally, intensification of agricultural production is inevitable and the sustainable management of water resources will play an increasingly important role in this equation.


How does climate affect water resources?

Climate impacts on water resources are varied in different river basins. The frequency of droughts and floods will increase under future climate conditions . Runoff and stream flow are more sensitive to rainfall than to evapo-transpiration. Efficient water use and integrated management will be increasingly important for reducing the impacts on water scarcity and droughts. Although many water management approaches have been adapted to mitigate climate impacts, there is still a need to determine local solutions. It is necessary to know how much water can be used in each irrigation area and the river basin, when the water is available, and how much water can be stored for use in the drought period, quantify variability of water resources over a long-term basis and associated links with energy and biodiversity.


How do water resources affect human life?

It is known that water resources play a vital role in human prosperity and crop productivity. The world’s agriculture, hydroelectric power, and water supplies depend on different components of the hydrological cycle, including the natural replenishment of surface and groundwater resources ( ACE, 2002). Water availability issues include how much water can be diverted, when the water can be available, and how much water can be stored in surface and groundwater reservoirs. The assessment of seasonal and long-term water availability is not only important for sustaining human life, biodiversity, and the environment, but also helpful for water authorities and farmers to determine agricultural water management and water allocation. Climate change is one of the greatest pressures on the hydrological cycle along with population growth, pollution, land use changes, and other factors (Aerts and Droogers, 2004 ). Water availability is under threat from changing climate because of a possible precipitation decrease in some regions of the world. In the light of the uncertainties of climate variability, water demand, and socioeconomic environmental effects, it is urgent to take some measures to use the limited water efficiently and develop some new water resources ( ACE, 2002 ). If the water resources are replenished by snow accumulation and the snowmelt process, the water system will be more vulnerable to climate changes ( Dracup and Vicuna, 2005 ).


How does knowledge affect agriculture?

Farmers’ knowledge can play a significant role in increasing water-use efficiency, which directly influences the agricultural water management schemes. Farmers should be aware of technologies that help to manage the water efficiently and to optimise the crop production without harming the environment.


What is catchment water balance?

Catchment water balance modelling is a major tool of agricultural water management in Australia. Several features of the Australian hydrological environment have had an effect on the development of the technology. The sparsity of streamgauging stations over much of the continent made assessment of available water difficult, and resulted in an emphasis on water yield instead of flood estimation in modelling studies. The sparsity of pluviometer stations promoted a reliance on generalized intensity–frequency–duration rainfall statistics for event-based flood estimation that delayed interest in continuous simulation water balance modelling for flood estimation until the last decade.


What is agricultural water management?

Given the existing constraints above, the agricultural water management sector is currently in the process of repositioning itself towards modern and sustainable service provision.

The project benefitted 135,000 farm families over a total irrigated area of 435,000 hectares, created 6,400 new jobs, and generally increased agricultural productivity. Yields per hectare were raised by up to 50% in on-farm improvement areas.


What percentage of water is re-allocated to agriculture?

However, future demand on water by all sectors will require as much as 25 to 40% of water to be re-allocated from lower to higher productivity and employment activities, particularly in water stressed regions. In most cases, such reallocation is expected to come from agriculture due to its high share of water use. Currently, agriculture accounts (on average) for 70 percent of all freshwater withdrawals globally (and an even higher share of “consumptive water use” due to the evapotranspiration of crops).


How much of the world’s freshwater withdrawals are agriculture?

Currently, agriculture accounts (on average) for 70 percent of all freshwater withdrawals globally (and an even higher share of “consumptive water use” due to the evapotranspiration of crops).

How does water quality affect food?

Water quality can be affected by poor planning of industrial sites, animal farms, and barnyards and feedlots. Until recently, the type of water source has been indicative of the potential risks of contamination. Poor water quality can affect the quality of food crops and lead to illness in those who consume them. For example, the water may contain germs that cause human disease. Irrigating crops with contaminated water can then lead to contaminated food products which lead to illness when eaten. Groundwater, for example, has been considered one of the safest sources of water. However, depending on field location and field size, it may not be possible to use water from these sources for irrigation.

What is AWM management?

AWM comprises a suite of management practices that includes, but is not limited to, watershed management, water capture, storage, conveyance, and application. This holistic focus is strategic because the sustainable and productive management of water requires attention to other factors, including inter alia, climate change and variability, crop selection, animal nutrition, maintaining ecosystem goods and services, and soil quality. For example, irrigation alone will not guarantee increased crop productivity on nutrient-poor soils; pests and diseases can severely diminish water productivity; and changes in precipitation or temperature may render some agricultural options untenable (Jones and Thornton, 2009).


What is a systems approach to AWM?

A systems approach to AWM begins with the identification of the significant contextual relationships. Analyzing the relationships among the components of a system provides an understanding of the connections and feedback loops among the relevant actors; practices in local crop and livestock farming systems, including tillage, soil fertility management, crop rotations, grazing patterns; availability and access to inputs (including, but not limited to water); geography; environmental water flows; transport; markets; and land and resource tenure. Understanding and building on these interactions is a hallmark of adaptive integrated water resources management (Boelee, 2011).


Why is agriculture important for development?

Agriculture is critical to development – the majority of the world’s poorest and hungry people depend on it for their livelihoods. Agriculture in turn depends on basic natural resources: biodiversity, soil, and water. Good stewardship of natural resources is central to sustainable development: agriculture’s long-term viability is a function of how well we – individuals and communities – fulfill our roles as stewards.


What is WRSA in agriculture?

A WRSA uses a systems approach to assess contextual dynamics and the relationships among water users and uses, including the water needed to maintain environmental flows and ecosystem health. It builds awareness of availability of and access to water resources, competing demands, legal and customary systems. It helps prioritize investments in agriculture water management (see Table 1) and “fosters a broader approach to integrated water resources management that facilitates more optimal and harmonious outcomes.” (USAID, 2013)
