The emergence of urban farming mainly for food production is one initiative in developing a sustainable environment.  This paper presents a brief conceptual review of the ideas, issues and imperatives in implementing urban farming on the rooftop areas. The concern is to investigate an alternative way for urban dwellers to achieve resilience through urban farming — the review is based on the theoretical background and concepts of the relevant constraints taken from various established references. The method adopts comparatives analysis explicitly through established texts and secondary data taken from previous cases.  The significant examples include; (i) green roof as rooftop farming in ensuring food security and reduce carbon footprint in Singapore; (ii) urban farming as a culture in emphasizing the domestic food production and consumption in Japan; (iii) rooftop urban farming in fresh urban food production in USA; and (iv) rooftop is effective as edible landscape and not only serve for visual purpose only in Thailand. These cases will lead to localize the concept of rooftop urban farming. There also will be a strategy for the greening of the cities by intensifying urban farming. This paper envisions to extend and establish the conceptual discourse for implementing urban farming on the rooftop areas in Malaysia.

Agro-industries should adopt effective strategies to use agrochemicals such as glyphosate herbicides cautiously in order to protect public health. This entails careful testing and risk assessment of available choices, and also educating farmers and users with mitigation strategies in ecosystem protection and sustainable development. The key to success in this endeavour is using scientific research on biological pest control, organic farming and regulatory control, etc., for new developments in food production and safety, and for environmental protection. Education and research is of paramount importance for food and nutrition security in the shadow of climate change, and their consequences in food production and consumption safety and sustainability. This review, therefore, diagnoses on the use of glyphosate and the associated development of glyphosate-resistant weeds. It also deals with the risk assessment on human health of glyphosate formulations through environment and dietary exposures based on the impact of glyphosate and its metabolite AMPA—(aminomethyl)phosphonic acid—on water and food. All this to setup further conclusions and recommendations on the regulated use of glyphosate and how to mitigate the adverse effects.

Current food production and consumption trends are inconsistent with the Convention on Biological Diversity’s 2050 vision of living in harmony with nature. Here, we examine how, and under what conditions, the post-2020 biodiversity framework can support transformative change in food systems. Our analysis of actions proposed in four science-policy fora reveals that subsidy reform, valuation, food waste reduction, sustainability standards, life cycle assessments, sustainable diets, mainstreaming biodiversity, and strengthening governance can support more sustainable food production and consumption. By considering barriers and opportunities of implementing these actions in Peru and the United Kingdom, we derive potential targets and indicators for the post-2020 biodiversity framework. For targets to support transformation, genuine political commitment, accountability and compliance, and wider enabling conditions and actions by diverse agents are needed to shift food systems onto a sustainable path.

This study examines the impact of increasing climate variability on food production in South Africa, focusing on maize and wheat yields. A two-way fixed effects panel regression model was used to assess the climate variability impacts, analysing secondary data for the period 2000 to 2019 for nine provinces in South Africa. The study found that increasing climate variability has a negative impact on maize and wheat production in South Africa. Specifically, the results indicated a negative correlation between mean annual temperature with both maize and wheat yields. A decrease in precipitation affected maize yields negatively, while the impact on wheat yields was positive, although insignificant. This analysis, therefore, depicted that crop yields generally increase with more annual precipitation and decrease with higher temperatures. The study recommends that funding initiatives to educate farmers on increasing climate variability and its effects on farming activities in South Africa should be prioritised.

In 2007-2008 the world food crisis has substantially aggravated. This is a good reason to ponder over the fate of our technological civilization and a reminder of the finite nature of the resources used by the mankind. These resources include minerals, land suitable for cultivation, water and, at last, the technologies for securing the growing world population with the foods. The crisis has opened the eyes of many enthusiasts of the scientific and technological progress to some of its bitter fruits, in particular, to the polarization of food production and consumption, hunger and poverty of millions human beings, environmental pollution, progressive exhaustion of resources. Still, there are enough reasons to be optimistic. Earth's civilization has survived many turning points and has always found the way out and the methods to resolve the problem. It may be hoped that the humanity will also found the way out from the maze of problems that showed up as a result of the food crisis, at least in the foreseeable future.
