Food Security: The Challenge of Feeding 9 Billion People

Continuing population and consumption growth can mean that the world demand for food will increase for a minimum of another forty years. Growing competition for land, water, and energy, additionally to the exploitation of fisheries, can have an effect on our ability to supply food, as can the pressing demand to scale back the impact of the food system on the atmosphere. the results of temperature change are an extra threat. however the globe can manufacture additional food and may make sure that it’s used more expeditiously and equitably. A multifarious and joined international strategy is required to confirm property and just food security, totally different parts of that are explored here. [1]

Soil Carbon Sequestration Impacts on Global Climate Change and Food Security

The carbon sink capability of the world’s agricultural and degraded soils is fifty to sixty six of the historic carbon loss of forty two to seventy eight gigatons of carbon. the speed of soil organic carbon sequestration with adoption of suggested technologies depends on soil texture and structure, rainfall, temperature, farming system, and soil management. methods to extend the soil carbon pool embody soil restoration and dry land regeneration, no-till farming, cowl crops, nutrient management, manuring and sludge application, improved grazing, conservation and harvest, economical irrigation, agroforestry practices, and growing energy crops on spare lands. a rise of one ton of soil carbon pool of degraded cropland soils might increase crop yield by twenty to forty kilograms per square measure (kg/ha) for wheat, ten to twenty kg/ha for maize, and 0.5 to one kg/ha for cowpeas. furthermore as enhancing food security, carbon sequestration has the potential to offset fossilfuel emissions by zero.4 to 1.2 gigatons of carbon annually, or 5 to fifteen of the world fossil-fuel emissions.

The story of phosphorus: Global food security and food for thought

Food production needs application of fertilizers containing phosphorus, gas and metal on agricultural fields so as to sustain crop yields. but fashionable agriculture relies on phosphorus derived from phosphate rock, that could be a non-renewable resource and current international reserves is also depleted in 50–100 years. whereas phosphorus demand is projected to extend, the expected international peak in phosphorus production is foreseen to occur around 2030. the precise temporal arrangement of peak phosphorus production may be controversial, but it’s wide acknowledged among the chemical business that the standard of remaining phosphate rock is decreasing and production prices are increasing. nevertheless future access to phosphorus receives very little or no international attention. This paper puts forward the case for together with semipermanent phosphorus inadequacy on the priority agenda for international food security. Opportunities for convalescent phosphorus and reducing demand also are addressed  along with institutional challenges. [3]

A multi-model assessment of food security implications of climate change mitigation

Holding the world increase in temperature caused by global climate change well below 2 °C on top of pre-industrial levels, the goal Affirmed by the Paris Agreement, may be a major social group challenge. Meanwhile, food security may be a high-priority space within the United Nations property Development Goals, that might probably be adversely full of tight climate mitigation. Here we tend to show the potential negative trade-offs between food security and climate mitigation employing a multi-model comparison exercise. we discover that carelessly designed climate mitigation policies might increase the amount of individuals in danger of hunger by one hundred sixty million in 2050. Avoiding these adverse aspect effects would entail a price of regarding zero.18% of worldwide gross domestic product in 2050. It ought to be noted that direct impacts of global climate change on yields weren’t assessed which the direct advantages from mitigation in terms of avoided yield losses may be substantial, more reducing the on top of value. though results vary across models and model implementations, the qualitative implications are strong and entail careful style of climate mitigation policies taking into consideration agriculture and land costs.

Influence of Water Management Structures on Household Food Security Status among the Smallholder Farmers in Kilifi Sub-county, Kenya

Inadequate quality-water could be a major hindrance to rural development and food security in arid and semi-arid areas of Republic of Kenya. Technologies which will promote water harvest and conservation are, therefore, instrumental in increasing resilience in continual droughts and enhancing food security in these dry lands. A study was disbursed in Kilifi sub- County within the coastal areas of Republic of Kenya one among the areas wherever food insecurity incidences are rife. The study geared toward assessing the influence of water management structures on food security standing among husbandman farming communities. Non experimental style mistreatment descriptive survey was adopted for the study. knowledge was analyzed mistreatment descriptive statistics and logistical regression to live the contribution of water harvest structures and irrigation to food security standing. Water harvest structures examined were: contour terraces, water pans, trash lines, boreholes, and unbroken strips. The results indicated that eightieth of the respondents were food insecure. The respondents who adopted boreholes and unbroken strips were two food secure whereas people who adopted water pans and trash lines were four food secure severally. to boot, people who adopted contour terraces were (8%) food secure compared to different water harvest structures. There was a big (P=0.05) positive relationship between the water management structures and food security this means that contour terraces, water pans, water harvest structures being economical, possession of deed of conveyance and land size are a number of the foremost important problems poignant food security in Kilifi Sub-county. To more enhance the understanding of food security and improve food insecurity standing in Kilifi Sub-county, adoption of water harvest structures ought to be promoted by all stakeholders. [5]
