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 ...

Using full-scale duckweed ponds as the finish stage for swine waste treatment with a focus on organic matter degradation
The rapid increase in the number of swine has caused pronounced environmental impacts worldwide, especially on water resources. As an aggregate, smallholdings have an important role in South American pork production, contributing to the net diffusion of pollution. Thus, duckweed ponds have been successfully used for swine waste polishing, mainly for nutrient removal. Few studies have been ...

Growth and survival of pacific coho salmon smolts exposed as juveniles to pesticides within urban streams in western Washington
Pesticides are frequently detected in urban streams with concentrations often exceeding those reported in surface waters within agricultural areas. We studied growth, survival, and return rates of coho salmon (Oncorhynchus kisutch) smolts exposed to a pesticide mixture (“cocktail”) representative of that most frequently reported within urban streams in western Washington State, USA, in fall ...

Urban and agricultural pesticide inputs to a critical habitat for the threatened delta smelt (Hypomesus transpacificus)
The Cache Slough complex is an area of tidal sloughs in the Sacramento‐San Joaquin River Delta of California, and is surrounding by irrigated agricultural lands. Among the species of concern in the area is the delta smelt (Hypomesus transpacificus), a federally‐listed threatened species. Releases of the organophosphate insecticide chlorpyrifos and pyrethroid insecticides were examined to ...

Clock House Farm: optimising growing conditions and irrigation efficiency in high volume soft fruit production - Case Study
Clock House farm nestles in the rolling hills of Kent a few miles south of Maidstone in the UK. The expansive 250 acre farm grows a variety of fruit, including strawberries, raspberries and blackberries. Notable innovators in horticulture, Clock House Farm were one of the first commercial growers to adopt table-top production of strawberries in the late 1990s. Since 2008 they have been using ...

One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas
All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the world’s agriculture is grown in areas of high water stress. This figure doubles when looking at irrigated cropland, which produces 40 ...

Don`t forget water in the true cost of biobased packaging
The additional 3 billion middle-class consumers expected by 2030 presents one of today’s greatest challenges, but they also provide one of the business community’s greatest financial opportunities. Against the backdrop of an increasingly resource-constrained world and volatile commodity prices, business as usual is not an option. The scalable, resource-efficient business models of ...

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, ...

Farm pond cleanup case study
Midwestern US Farm Pond Cleanup Using Microcat AL3 Pond Cleaner Problem A three-acre farm pond containing approximately 9 million gallons of spring water and rainwater runoff in the Midwestern United States is experiencing high suspended solids with related fish die off. The fish population includes 5 lb bass, blue gill and crappie bass. The problem is more acute in the warm summer months. The ...

Agricultural water poverty in Marvdasht County, Southern Iran
The paper discusses the application of the Agricultural Water Poverty Index (AWPI) as an assessment tool for agricultural water in rural areas of Marvdasht County, Fars Province, Iran. Along with the global concern, water has become an increasing concern during the recent years in Iran. This paper provides an overview of the AWPI and the methodology to measure AWP by addressing the four key ...

Integrated modelling of a coupled water-agricultural system using system dynamics
An integrated System Dynamics Model for the water-stressed Rosetta region, Egypt, assessing water balance, and agricultural yield and revenue to 2050, is presented. The study uses 57 simulations to better understand impacts on water, food and economic security and their interactions, in order to highlight potential pathways towards a more sustainable future for the Rosetta region. Current water ...

Review of agricultural water management policies in Near East and North African Region in light of water scarcity
This paper explores the current debate about water management policies and the factors affecting their formulation and implementation in the arid and semi–arid zones of the Near East and North African Region (NENAR). In this context, relevant and significant experiences of other countries in the world facing similar challenges are also considered (Sachdeva, 2009). The literature pertaining ...

The impact of climate change and soil salinity in irrigation water demand on the Gaza Strip
The presented work analyzes the potential impacts of the temperature, precipitation changes and water salinity on agricultural water demand. The study was carried out on five representative orchard crops (olive, palm, grapes, citrus and guava) that cover around 83% of the orchard farms in Gaza Strip. To achieve this goal, CropWat modeling software version 8.0 is used to calculate the ...

Nitrate leaching from a potato field using adaptive network-based fuzzy inference system
The conventional methods of application of nitrogen fertilizers might be responsible for the increased nitrate concentration in groundwater of areas dominated by irrigated agriculture. Appropriate water and nutrient management strategies are required to minimize groundwater pollution and to maximize nutrient use efficiency and production. Design and operation of a drip fertigation system ...

Land, water, and forests : assets for climate resilient development in Africa
Africa is a continent rich in natural resources. Its land, water, and forests underpin the sustained productivity of food crops and livestock on which millions of Africans depend directly for their livelihood and survival. These resources are major assets on which most countries depend for economic growth and sustainable development. In the face of growing climate change threats, such as ...

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 ...

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 ...
