Variability in water cycles driven by climate change is considered likely to impact rice production in the near future. Rice
is the main staple food for the population in the lower Mekong Basin and the demand for food is expected to grow due to increase
in population. This paper examines the impact of climate change on rice production in the lower Mekong Basin, evaluates some
widely used adaptation options, and analyses their implications for overall food security by 2050. Climate change data used
in the study are the future climate projection for two IPCC SRES scenarios, A2 and B2, based on ECHAM4 General Circulation
Model downscaled to the Mekong region using the PRECIS (Providing Regional Climates for Impact Studies) system. In general,
the results suggest that yield of rainfed rice may increase significantly in the upper part of the basin in Laos and Thailand
and may decrease in the lower part of the basin in Cambodia and Vietnam. Irrigated rice may not be affected by climate change
if increased irrigation requirements are met. Negative impact on the yield of rainfed rice can be offset and net increase
in yield can be achieved by applying widely used adaptation options such as changing planting date, supplementary irrigation
and increased fertilizer input. Analysis of the projected production, considering population growth by 2050, suggests that
food security of the basin is unlikely to be threatened by the increased population and climate change, excluding extreme
events such as sea level rise and cyclones. 相似文献

The 2007–08 food price crisis has not only increased food insecurity around the globe, but also exposed long-term failures
in the functioning of the world food system. Establishing a global governance architecture for governing food, nutrition,
and agriculture as well as improving market functioning and increasing investment in public goods will be critical for the
way forward. Three high-priority policy actions are necessary to cope with urgent needs for food and nutrition security and
at the same time build a stronger food system that can respond to future challenges: (1) improve productivity and scale up
research investments; (2) expand nutrition and social protection, (3) strengthen markets and trade.

ABSTRACTProcessed foods, generally known as modified raw foods produced by innovative processing technologies alters the food constituents such natural enzymes, fatty acids, micronutrients, macronutrients and vitamins. In contrast to fresh and unprocessed foods, processed foods are guaranteed to be safer, imperishable, long lasting and consist high level of nutrients bioactivity. Currently, the evolution in food processing technologies is necessary to face food security and safety, nutrition demand, its availability and also other global challenges in the food system. In this scenario, this review consists of information on two food processing technologies, which effects on processed foods before and after processing and the impact of food products on human health. It is also very well established that understanding the type and structure of foods to be processed can assist food processing industries towards advancement of novel food products. In connection with this fact, the present article also discusses the emerging trends and possible modifications in food processing technologies with the combination of conventional and modern techniques to get the suitable nutritional and safety qualities in food. 相似文献

Mechanisms of global governance, developed in response to initiatives adopted by the FAO to combat hunger and confront food crises, are the result of wide ranging historical debates using three basic criteria for justification: the scientific, the political‐ideological, and the ethical. On the basis of these criteria, certain forms of understanding and acting on agriculture, health and nutrition at global level have come to be accepted as valid. Currently the debate and the resulting proposals are based on the recognition of food as a universal human right. 相似文献

The most vulnerable groups in terms of food security during floods in south Asia under climate change will be the poor, women
and children. Current procedures for the transfer of climate adaptation funds tend to marginalize these groups. Food production
is being disrupted by flooding more frequently and more severely than before, due to climate change. By 2080 the situation
is likely to be much worse than at present. Adaptation has to encourage management of all stages of food security, from the
farm to the consumer, both urban and rural. Measures have to be participatory, from the community to the international level.
While many individual initiatives offer hope and demonstrate good practice, institutional, economic and environmental factors
may all impede the maintenance and enhancement of food security in south Asia. Innovative forms of food production, distribution
and storage will have to be developed.

This paper features the composition of wild fruits, their exploitation and their potential contribution to improved food and
nutritional security in three districts of the Amhara region of Ethiopia. Data were gathered through structured, semi-structured
and key-informant interviews which were administered to the heads of 92 randomly chosen households. Focus group discussions
and direct field explorations by the researchers were also undertaken. The results revealed that altogether 44 wild fruit
species are available for use in the study areas. The fruits are rich in valuable nutrients and are accessible year-round
with significant overlap at times of acute food and nutrient scarcity. Nevertheless, owing to the peoples’ cereal-based dietary
habits, cultural perceptions and attitudes, the current state of fruit utilization is very low. Consequently, the potential
nutritional contribution of wild fruits to the people’s diets remains largely unexploited. In order to remedy this situation,
a wider and sustained acceptance of wild fruits as important dietary components must be fostered.

Drying is a widely used technique in sub-Saharan Africa which allows food conservation, weight reduction and added value for some products. However, the technique is quite complex, making the rational concept of drying devices challenging. A rational method for the design and the construction of a fruit and vegetable solar dryer is presented. A prototype was designed and constructed at the Université Libre de Bruxelles (Belgium) to test the concept and was found to be capable of drying more than 40 kg of fresh tomatoes in 10 h. A second prototype was constructed in Bandiagara (Mali) by both local craftsmen and students from the Université Libre de Bruxelles, using local materials. Speed of drying and prevention of food spoilage was far superior to that of traditional solar dryers. Based on these prototypes, a dryer industry is being constructed in Bandiagara in order to increase food self-sufficiency. 相似文献

The term “food security” has been used over time to mean different things. This brief article discusses the various meanings
attached to the concept and suggests that it can be a useful measure of household and individual welfare, particularly if
combined with estimates of household food aquisition and allocation behavior. If nutritional security is the goal of interest,
estimates of access to food should be combined with estimates of access to clean water and good sanitation. Anthrometric measures
are likely to be more appropriate than food security estimates to target policies and programs to improved child nutrition.

The World Food Summit in 1996 set the goal of reducing by half the numbers of malnourished people in the world by 2015. It
is unlikely that this will be reached, and particularly not in Sub-Saharan Africa (SSA). Food imports in SSA have increased
in the past 40 years, since domestic production could not keep up with population growth. Several studies have reported about
this stagnating food production in SSA. However, this region encompasses a large number of countries, with a great variety
of agroecological zones and large differences in land, labour and other resources. The objectives of this paper are to analyse
agricultural production and food security in eight countries in Sub-Saharan Africa over the past 40 years, and to investigate
to what extent these countries have followed different agricultural development pathways and are faced with different constraints.
The analysis is largely based on statistical data, mainly from FAO, and on other information from various national and international
sources. It shows that some of these countries have struggled to achieve and maintain overall national food security, while
others have been able to achieve more than that and increased production at a faster rate than population growth. It subsequently
analyzes major development constraints, with regard to labour, land and water, and institutions, pinpoints certain positive
developments that have taken place in some of the countries and looks at opportunities for the respective countries to improve
their food situation. One of its conclusions is that more attention should be paid to country specific constraints and opportunities. 相似文献
