Soil Degradation and Food Security Coupled with Global Climate Change in Northeastern China

The northeastern China is an important commodity grain region in China,as well as a notable corn belt and major soybean producing area.It thus plays a significant role in the national food security system.However,large-scale land reclamation and non-optimum farming practices give rise to soil degradation in the region.This study analyzed the food security issues coupled with global climate change in the northeastern China during 1980–2000,which is the period of modern agriculture.The results of statistical data show that the arable land area shrank markedly in 1992,and then increased slowly,while food production generally continually increased.The stable grain yield was due to the increase of applied fertilizer and irrigated areas.Soil degradation in the northeastern China includes severe soil erosion,reduced soil nutrients,a thinner black soil layer,and deterioration of soil physical properties.The sustainable development of the northeastern China is influenced by natural-artificial binary disturbance factors which consist of meteorological conditions,climate changes,and terrain factors as well as soil physical and chemical properties.Interactions between the increasing temperature and decreasing precipitation in the region led to reduced accumulation of soil organic matter,which results in poor soil fertility.Human-induced factors,such as large-scale land reclamation and non-optimum farming practices,unsuitable cultivation systems,dredging,road building,illegal land occupation,and extensive use of fertilizers and pesticides,have led to increasingly severe soil erosion and destruction.Solutions to several problems of soil degradation in this region requiring urgent settlement are proposed.A need for clear and systematic recognition and recording of land use changes,land degradation,food production and climate change conditions is suggested,which would provide a reference for food security studies in the northeastern China.

Food Security： Where Are We Heading？

The issues of food security are an important aspect of every country for its social and economic growth and the eradication of poverty. It is particularly crucial for satisfying the needs of the ever-growing population in developing countries. Agriculture is the backbone of the people and the economy for developing countries, particularly in highly populated countries such as India, China and South East Asia. The world population is anticipated to rise to 8.3 billion by 2030 and to 9.2 billion by 2050. By that time, to feed the growing population, food production must double to keep pace with the escalating food demand. Agricultural commodities showed increases of 58.9% in import dependency ratio （IDR） as compared to 32.2% in 2013. Thus, this study attempts to review and explore the challenges of food security as well as the opportunities of the seed industry in Malaysia.

Relevance of Dried Meat Product （Kundi）, an Intermediate Moisture Meat, for Food Security

The main goal of food security is for individual to be able to obtain adequate and quality food needed at all times, and to utilise the food to meet the body needs. Kundi is a relish Intermediate Moisture Meat （dried meat） product, produced in the Northern part of Nigeria. 2-3 years old male Camelus dromedarius and White Fulani animals were used for this study, 2 kg of semimembranous muscles from each animal were used, and trimmed of all external fat, connective tissues and bones. Meat samples were cut in sizeable pieces of weight ranges 70-90 grams of 6-8 cm and kept in the refrigerator for 24 hours. Fresh meat cuts were boiled for 20 minutes at 100 ~C, seasoned and oven dried for 3 hours at 170 ~C. This study assessed the proximate composition of fresh and dried meat （Kundi） products and their sensory evaluation in a completely randomized design. The results showed that fresh camel meat had 74.55% and 21.96% significantly （P 〈 0.05） higher in moisture and protein content than 72.69% and 18.96% of fresh beef, while fresh beef had higher （P 〈 0.05） ether extract （6.34%） than fresh camel meat （2.39%）. Laboratory Prepared Beef Kundi （LPBK） had the highest （P 〈 0.05） value in moisture content 35.09% followed by Laboratory Prepared Camel ＇Kundi＇ （LPCK） with 33.21% while Commercial Kundi （CK） had the least. Protein obtained was inversely proportionally to moisture content. Ether extract for LPCK and LPBK were statistically similar （P 〉 0.05） and both were lower （P 〈 0.05） than value obtained for CK. The results obtained for sensory evaluation showed that the panelist rated seasoned Kundi to have the highest significant （P 〈 0.05） valve for tenderness, flavour, colour, juiciness, texture and acceptability with values 6.50, 5.30, 6.50, 6.53, 6.30 and 7.00 respectively. Study showed that dry meat products （Kundi） is of high nutritional qualities, and could be of a great relevance; to food security.

Present Situation and Development of Chinese Grain Food Safety

The recent outstanding issues,＂ puzzles of farmers, anxiety oflocal government and helplessness ofcentral government,＂ facing Chinese grain security, depend on the lack of national food security strategy. Therefore, we must reconstruct our national food security strategy with a cornerstone of an integrated productivity, the focus control of market regulation forces and the protection of sovereignty. By analyzing the status of integrated productivity, market regulation force and sovereign control, this essay proposes that we should change the concept from ＂ food production＂ to ＂foOd management＂, design the two systems of the interest coordination and the special safeguard, effectively improve the enthusiasm of the government＇ s undertaking work in grain-producing areas and farmers＇ farming work, firmly grasp the two initiatives of acquisition and processing of grain and operating inputs, and actively apply recommendations of the two regulators： food exports, processing and conversion.

The Impact of Climate Change on Sustainable Food Supply and Environmental Safety in Ekiti State, Nigeria

The resultant climate change on sustainable food supply has greatly affected agricultural production by the level of great volumes of gasses emitted into the atmosphere by human activities. The human factors that emit large amount of green house gases include industrialization, burning of fossil fuel and gas flaring. Increase in air temperature and consequent increase in the rates of evaporation also affect the level of food supply. Data for this study were collected from primary and secondary sources. Primary source were collected through field investigation and structured questionnaire. A total of 450 questionnaires were administered. Results revealed that varieties of crops ranging from tree crops to cereals were cultivated within the study area. The effect of climate change on food supply has resulted into change in crop yields, change in rainfall pattern, soil loss and has greatly affected planting period and harvesting. The study therefore recommended awareness campaigns on the causes and consequences of global climate change on food production, environmental education and afforestation campaign programmes on sustainable food supply and environmental safety must be intensified.

Food security status in rural areas of Mizoram,Northeast India

Rural areas practice subsistence of the Mizoram state, India agriculture where shifting cultivation dominates the farming systems. As a result, output from crops is very low and thus, the rural areas suffer from food insecurity. This paper analyses food security status in the rural areas of Mizoram and suggests the measures to attain food security. A case study of 16 villages, lying in all the eight districts of Mizoram, was conducted in 2014 and 1527 households （76%） out of total 2010 households were surveyed through purposive random sampling method. Structured questionnaire was constructed and questions on three food security components and 13 indicators were asked. We used Z score technique to calculate data and finally got a composite score of all the components of food security. Our result shows that food availability in the study villages is very less as composite score stands for o.oo3 whereas food accessibility is comparatively higher, mainly due to availability of fair price shops （mean value is one）, high agricultural working population （40.1%） and high literacy rate （70.6%）. Therefore, its composite score is 0.236. Food stability scores only -0.062 and finally overall food security stands for 0.178, which is inadequate. We have suggested that‘system rice intensification＇, which is already in practice, should be given priority. Adequate irrigation facilities, proper public distribution system, cultivation of fruits and vegetables, value addition in farm products and access to market may achieve food security.
