China: agricultural production and groundwater
As in many parts of the People’s Republic of China, Shanxi Province is experiencing reduced water security for the agriculture sector. Changing climate conditions, including reduced rainfall, are increasing reliance on groundwater resources in the province. Unsustainable groundwater use for food production intensifies the impacts of climate change, and cost-effective adaptation responses ...

Accounting for the market and non-market values of multifunctional outputs in evaluating water transfers to non-agricultural uses: empirical evidence from Taiwanese rice production
Increased demand for water for municipal and industrial uses throughout Taiwan has intensified the pressure to re-allocate water from agricultural to non-agricultural uses. The full policy implications of such water transfers must not only account for the value of lost agricultural production and income, but also any loss in the social value of multifunctional benefits from agricultural ...

Analysing the links between agriculture and climate change: can 'best management practices' be responsive to climate extremes?
Rural communities the world over depend on agriculturally–based livelihoods. In the Canadian prairies, access to sufficient quality and quantity of water can be challenging. Agriculture is fundamentally susceptible to access to water during critical crop germination and growth periods. Climate change models for the Canadian prairies indicate, in general, that summer growing seasons will ...

Food and water insecurity: re-assessing the value of rainfed agriculture
ABSTRACTRainfed agriculture has potential to produce needed cereals for the growing populations of West and Central Asia even though rainfed agriculture is perceived as risky. The value of rainfed agriculture to produce competitively should be re-assessed. This requires the concerted efforts of farmers, researchers, and policy makers to work on the technical factors that determine agricultural ...

A policy option for valuing irrigation water in the dry areas
Participants at the international conference on policies for water and food security in the dry areas, held in June 2013, agreed that, given the fast pace of depletion of groundwater, the issue of water valuation in the dry areas is no longer one of whether or not, but rather of how. Policies that have been or are perceived to have adverse effects on the cost of agricultural production or food ...

Conjunctive effect of water productivity and cultivation pattern on agricultural water management
Agricultural water resources are scarce in Iran, and agricultural water management is essential to overcome this limitation. Determination of the water productivity index (WP) using the methods of optimization of cropping patterns and optimal water allocation is the most effective tool in water management in the agricultural sector. In this study, a non-linear optimization model was used to ...

Measuring drought based on a CGE model with multi-regional irrigation water
There have been many droughts in China that have caused severe losses. Previous studies evaluating droughts were from meteorological and hydrological perspectives. We measure the Chinese drought of 2000 based on a static computable general equilibrium model of China's macroeconomy, which describes the relationships between drought, agricultural production, and rural households' welfare from ...

Sustainable Management of Large Scale Irrigation Systems: A Decision Support Model for Gediz Basin, Turkey
While water on a global scale is plentiful, 97% of it is saline and 2.25% is trapped in glaciers and ice, leaving only 0.75% available in freshwater aquifers, rivers and lakes. About 70% of this fresh water is used for agricultural production, 22% for industrial purposes and 8% for domestic purposes. Increasing competition for water for domestic and industrial purposes is likely to reduce the ...

Assessing the cost, effectiveness and acceptability of best management farming practices: a pluri-disciplinary approach
The AgriBMPWater project has been imagined and built in a pluri-disciplinary approach and framework, with the study of the object 'BMPs' using several disciplines at the same time (hydrology, economy, sociology, geography and agronomy). The knowledge of the object in each discipline is deepened by a fertile multi-field contribution: borders of disciplines have been broken down, allowing ...

Can water use efficiency be modeled well enough to impact crop management?
Crop water use efficiency (WUE, yield per unit of water use) is key for agricultural production with limited water resources. Policymakers and water resource managers working at all scales need to address the multitudinous scenarios in which cropping systems and amounts, timing and methods of irrigation, and fertilizer applications may be changed to improve WUE while meeting yield and harvest ...

Innovative farm policies and their impact in a French frontier zone: reviving old conflicts in Guadeloupe (FWI)?
Society now expects agriculture to fulfil new functions to improve quality of life. This requirement has been reinforced by recent crises. The 1999 French Agricultural Framework Law (LOA) formalised agricultural multifunctionality and included payments to farmers for new practices, which satisfy both social and environmental functions, in addition to economic ones. A voluntary territorial farm ...

The water we eat
Agriculture imposes a heavy and growing burden on Europe's water resources, threatening water shortages and damage to ecosystems. To achieve sustainable water use, farmers must be given the right price incentives, advice and assistance. Food is intrinsically bound to human wellbeing. Besides the importance of good food for good health and the pleasure we derive from eating, agricultural ...

Agroecology Taps a Wellspring of Farming Knowledge
Agroecology shares family farmers' evolving knowledge — and should go mainstream, says Fernando R. Funes-Monzote. Over recent decades, formal research and extension, led by governments and big enterprises, have led to novel answers for emerging problems in agriculture. However, these have generally failed small-scale farmers — one fifth of the world's population. Every day, ...
