Food security is a worldwide challenge that related to the basic human needs of sustainable development [...]
As a major cereal crop, rice (Oryza sativa L.) is crucial to food security for at least half the world population. New varieties with high yield potential, good quality and high resistance to biotic and abiotic stresses are needed in order to meet the demand for more food arising from the rapid human population growth and concurrent decrease in arable land. Improvement of rice quality has now b...
Population growth, arable land and fresh water limits, and climate change have profound implications for the ability of agriculture to meet this century's demands for food, feed, fiber, and fuel while reducing the environmental impact of their production. Success depends on the acceptance and use of contemporary molecular techniques, as well as the increasing development of farming systems that...
Man-made habitats in central Europe can be broadly divided into arable land with weed vegetation, and settlements and their surroundings, harbouring ruderal vegetation. The former is a predictable environment with frequent, regular and large-scale disturbances, while the latter is an unpredictable environment with irregular disturbances of varying spatial extent producing heterogeneous mosaics ...
Relevance Concerns about the environmental impact of farming has increasingly been the focus of discussions in the EU. Croplands, a primary land use in Europe, have a significant impact on the environment (soil, water bodies, global climate, local biodiversity and human health). The use of fertilisers and pesticides associated with conventional farming may lead to pollution and/or climate chang...
Buffer strips on agricultural land have been shown to protect surface water quality by reducing erosion and diffuse pollution. They can also play a key role in nature conservation and flood risk mitigation as well as in the design of bioenergy landscapes resilient to changes in climate, environmental pressures from intensive agriculture and policy developments. Use of conservation buffers by fa...
A griculture is the dominant sector in the Gambian economy, employing about 70% of the total work force and contributing, on average, 33% of GDP. It produces about 50% of the national food supplies with only about 60% of the country’s total arable land resources currently being utilized. The sector generates approximately 40% foreign exchange earnings and provides two-thirds of total household ...
1. Japan is an island with approximately 70% of land covered by mountain forests and where arable space is limited. Fishing communities are located in all coastal areas nationwide. Food resources from the ocean have historically played a significant role in the Japanese diet. Even today, around 40% of protein consumed by Japanese people comes from sea food. 2 Ensuring the long-term sustainabili...
Land suitability analysis, commonly known as land evaluation, is considered an interface between land resourcesurvey and land use planning and management. Land evaluation be carried out to estimate the suitability of land fora specific use such as arable farming or irrigated agriculture. There are several established techniques for generatingland suitability evaluation. This research was carrie...
