The world is facing changes that have a significant impact on the environment and every aspect of human life. Currently, 588 million of the world's 7.8 billion people live in extreme poverty, 820 million people are starving, and 2.5 billion suffer from some form of micronutrient deficiency. The population is growing, the processes of aging and migration to urban settlements are actively underway, which is reflected in agricultural production and food demand. At the same time, the impact of the effects of climate change on the state of food security in the world is noteworthy. In addition, inequality, discrimination, and human rights abuses (including the right to adequate and safe human food) exacerbate these consequences, especially for small farms. According to the FAO, 33% of world population growth is expected in the near future. The population, from the existing 7.7 billion, will reach almost 10 billion by 2050. The population growth will lead to a strong increase in food demand. By 2050, it will be necessary to produce 70 percent more than 50-types foods, while the share of agriculture in global GDP is about 4%. While investments and innovations in the agricultural sector are increasing, the growth rate of yields is quite low. The rural population is declining and the aging process is actively underway, which has a serious impact on the labor force. Added to this is the fact that the current use of natural resources is irrational and under severe pressure. Twenty-five percent of agricultural land is severely degraded and land has long been recognized as a limited resource, while water resources are under heavy strain and there is a shortage of water in the world. Food losses and waste are an inefficient side of the sector and a strong threat to the environment. Up to 33% to 50% of the world produced food is never used for food, and the cost of these products exceeds $ 1 trillion. These trends have led to the problem of food shortages. As a result, poverty and hunger have intensified in the world. Moreover, there are four main factors that put pressure on the inherited model of agricultural production, without their solution the sector will not be able to cope with future demands. They are exacerbating the problem of hunger and food shortages in the world, putting pressure on agriculture and the ability of the sector to be able to meet future needs. These factors include: demographics, scarcity of natural resources, climate change, and food losses and waste. In Summary, overcoming these challenges requires the joint efforts of governments, investors, and innovative agricultural technologies to increase productivity and support the transition to an economy based on innovation and knowledge. Modern farms and enterprises have to work differently, mainly due to the use of technological advantages. In the future, agriculture must use sophisticated technologies and advanced equipment. Precision farming and the use of robotic systems ensure more profitable, efficient, safe and environmentally friendly agricultural production. According to the FAO report, these efforts require considerable resources: to eradicate hunger by 2030 and deal with the demographic pressures that will require an annual investment of $ 265 billion. Keywords: Agri-food sector, poverty, hunger, food security, food losses and waste.

Understanding the dynamics of food production is critical to improving food security. This is particularly important in regions that rely on subsistence agriculture with little adaptive capacity to climate change. Sorghum plays an important role in food security in some of the poorest parts of the world. This article reviews the literature to identify and examine the major factors affecting sorghum production in three major production regions. Factors were not categorized ex ante but rather determined from the review. Ten major factors were identified as having notable impacts on sorghum production: climate change, population growth/economic development, non-food demand, agricultural inputs, demand for other crops, agricultural resources scarcity, biodiversity, cultural influence, price and armed conflict. This synthesis revealed that (1) multiple factors simultaneously affect sorghum production; (2) the effect of each factor is greatly influenced by the magnitude and certainty of one or more other factors; and, (3) factors differ in relevance and degree with regard to geography. Generally, improved agricultural inputs, population growth/economic development and climate change have substantial influence on sorghum production. However, local dynamics likely go beyond these broad trends and more exhaustive, locally-focused studies are needed for actionable planning purposes.

Averting robo-bees: why free-flying robotic bees are a bad idea

Insect Interactions

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.
