Factors influencing immigrants’ satisfaction in Danjiangkou Reservoir based on logistic regression model
Findings from a prospective study of project-induced migration along the middle route of the South-to-North Water Diversion Project in China are reported. The study seeks to identify the key factors influencing differences in immigrants’ satisfaction, from their own characteristics, family income, production conditions, living conditions, social conditions, resource conditions, and ...

Recycling of macronutrients from sea to land using mussel cultivation
The presence of diarrheic shellfish toxins (DST) has been the main obstacle to mussel cultivation in Sweden. Monitoring of DST concentrations in mussels by HPLC for 12 years has shown great geographical and seasonal differences. Furthermore, individual mussels on the same farming strip may differ by a factor as great as 16. DST levels are usually low in summer, rise in September, remain high in ...

Adaptation of the agricultural sector to the effects of climate change in arid regions: competitive advantage date palm cropping patterns under water scarcity conditions
This research paper highlights the adverse effects of climate change on the agricultural sector in Saudi Arabia and the actions taken to adapt to these adverse effects. Special focus was given to the potential to optimise the reallocation of scarce water resources among the competitive advantage date palm cropping regions in Saudi Arabia using a mathematical sector modelling approach. The ...

Impact of Bt cotton on farmer livelihoods in South Africa
The economic benefits of Genetically Modified (GM) crops in developing countries have been well documented, but little research has been undertaken to date on the impacts of GM adoption on household livelihoods. The research reported here aimed to assess the livelihood impacts of the adoption of Bt cotton in South Africa., and involved 100 interviews of resource-poor farmers growing Bt cotton in ...

Quantitative assessment of the impacts of irrigation on surface water fluxes in the Tarim River, China
Irrigation is a significant human activity that affects surface water fluxes in the Tarim River Basin. To quantitatively assess the irrigation impact of this activity on surface water fluxes in the Tarim River, a land surface hydrologic model was coupled with a modified irrigation scheme and a reservoir module and applied to simulate these fluxes. Modeling results indicate that the combined ...

Soil Management for Sustainable Agricultural Productivity in Bangladesh
Introduction: The 'rules of road' by which agricultural researchers measure the impact of their work are being restudied. The first conclusion is that it is impossible to choose between food needs of today and food needs of 100 years from now. Somehow the food production system in Bangladesh must keep pace with the demand that 9 million new mouths place on it every year. Second, the natural ...

How to use organic fertilizer equipment to improve soil environment
Soil fertility has a great impact on crop yield and economic benefits. Soil fertility has declined and harvest has decreased, resulting in agricultural losses. Huaqiang equipment factory provides a complete set of professional organic fertilizer production equipment to help improve the agricultural soil environment. Three main reasons for the decline of soil fertility 1. The local land ...

How to maintain soil fertility
In order to maintain soil fertility, some low-yield soil (acid soil, alkali soil and salt soil), chemical improvers and irrigation should be used to improve, remove obstacles and improve the fertility level. In addition, reasonable cultivation and rotation should be carried out to regulate the nutrients and water in the soil and prevent some nutrient deficiency and water vapor imbalance. 1. ...

In-situ soil moisture conservation: utilisation and management of rainwater for crop production
The salient results of in-situ soil water conservation technologies that have been found suitable for increasing soil moisture in the arid and semiarid lands of eastern Kenya are reviewed. The results showed that Zai pits, tumbukiza and deep tillage when used together with soil fertility improvement can increase crop yields by 4–10 times in comparison to conventionally cultivated fields. ...

Can medicinal plants alleviate poverty and protect Nepal’s fragile environment?
Farmers in the high Himalayas partner with a U.S.–based nonprofit to cultivate medicinal plants — and the environmental and economic benefits they offer. On a trip to their childhood home in eastern Nepal in the early 2000s, Nepalese staff members of the Mountain Institute — an organization headquartered in Washington, D.C., that works to protect mountain environments and ...

Why to use sulphur coated urea fertilizer
With the continuous improvement of the level of agricultural science and technology, the promotion of high-yield varieties, the improvement of land re cultivation index, and the vigorous development of economic crops, flowers and urban greening. The growth of crops and the ecological balance of nutrients in the soil are becoming more and more serious, and the phenomenon of crop sulfur deficiency ...

Peru: Olmos irrigation project sparks development debate
The recently launched irrigation and hydropower Olmos megaproject in Peru is hailed a ‘masterpiece of engineering’ aimed at stimulating rural development — but some fear the initiative will mostly benefit big companies. The project will bring water from the Atlantic side of the Andes to the Pacific side through a tunnel in the mountains, to irrigate the arid Olmos Valley in the ...

Facts & figures on palm oil
Introduction Palm oil is a vegetable oil that is a common ingredient in a wide variety of products, ranging from biscuits, bread and noodles to shampoo, candles and deter-gents. It has been estimated that around half of all packaged items found in supermarkets contain it. Palm oil is also used as biofuel. The use of palm oil is expected to continue growing, with an esti-mated doubling of use by ...

Access to Energy: Empowering India’s Rural Communities
Tucked away in the southwestern corner of Odisha in the Bay of Bengal, the village of Keragam is home to around 230 families, most of whom are farmers. They live about 30km from the nearest town, while the state capital, Bhubaneswar, is an 11-hour drive away. Those who work the land here do so in relative isolation; they grow rice and sugarcane as best they can, in a patchwork of green and brown ...

What is the difference between traditional and modern farming?
Agricultural systems in various parts of the world have evolved due to technological advances and increasing human knowledge. It develops from primitive agriculture, traditional agriculture to modern agriculture. At that time, hunting and gathering activities are familiar techniques for humans. Conventional agriculture started since humans began to settle and cultivate in one location. This ...
