Introduction
Food security is one of the most critical global issues that is constantly changed by climate variability, market instability, public health challenges, and socio-economic disparities. Although the adoption of strategies such as crop diversification, improved livestock nutrition, and healthcare-linked food interventions has been strong and shown potential, they are still limited in scope due to a lack of long-term evidence, cultural relevance, economic viability, and policy support. Most areas, particularly those that are poor in resources, still find it hard to create the sustainable and resilient food systems they need. The following dissertation titles inform these gaps by suggesting new research avenues that will lead to stronger sustainability in agriculture, improved market and policy frameworks, better nutrition via healthcare systems, and greater food security for different populations.

Proposed PhD Title 1: Designing Climate-Responsive Crop Diversification Models: Integrating Long-Term Soil Health, Economic Viability, and Farmer Adoption in Sustainable Agriculture
Mihrete and Mihretu (2025), in their systematic review published in Global Challenges, point out that crop diversification is at the core of sustainable agriculture, climate resilience, and food security. Nonetheless, insufficient long-term evidence on soil health impacts, different financial returns during the initial transition periods, and farmers’ socio-cultural doubts slow down its extensive adoption among the major practices. The writers further direct that the majority of the present studies deal with short-term, very narrow or specific to the particular situation, thus leaving the growers without any clear information on how the diversification is performing ecologically and economically in different climatic conditions. This situation creates doubts, particularly among the smallholder farmers, who are already facing high risks and have, at the same time, limited resources.
Problem Statement:
Crop diversification is suggested as a way to sustainable agriculture, but its future ecological and economic effects are still not clear, especially for smallholder farmers. Several diversification methods have not been evaluated over multi-year periods, which leads to uncertainty regarding the durable positive effects on soil health, biodiversity, climate resilience, and profitability. Since smallholders are working under the constraints of resources and markets, the lack of robust long-term proof will not only limit their adoption of diversification but also weaken the policy efforts that are aimed at supporting the transition to sustainable farming practices.
Research Gap:
Most of the presently available studies deal with short-term issues and do not consider how soil quality, ecosystem services, or financial returns would be affected over the long run. In addition, there are not many studies that compare different agro-ecological zones, especially with respect to the initial input costs, yield variations and market restrictions that matter for long-term sustainability. Lack of integrated, long-term analysis blocks the manifestation of informed farmer decision-making and the establishment of evidence-based policy.
Research question:
What are the ways of designing climate-responsive crop diversification models so that they can optimise long-term soil health, economic viability, and farmer adoption under different agro-ecological conditions at the same time?
Outcome:
A validated, region-specific diversification model integrating soil health, economic projection, climate risk, and adoption strategies will be developed to assist in making evidence-based decisions for sustainable agriculture.

Proposed PhD Title 2. Building Resilient Agri-Food Systems: A Framework for Policy Effectiveness, Market Access, and Ecosystem Service Measurement in Crop Diversification
Crop diversification has the potential to be a game changer in terms of ecological stability, market resilience, and sustainability, according to Mihrete and Mihretu (2025), but the full realisation of this potential is somehow grounded. The authors list among the obstacles a lack of policy support, poor market infrastructure, and the inability to measure ecosystem services. The authors’ review indicates that the farmers are still having a hard time getting access to reliable markets for non-traditional crops, among others, and thus lack of confidence in diversification as a long-term strategy does not help the situation. Furthermore, no common tools are available for the measurement of benefits like pollination, pest control, and soil ecosystem functions, which is one of the reasons why policymakers and stakeholders have not yet appreciated—and hence, not rewarded—the value of diversified systems to the full extent.
Problem Statement:
Crop diversification is a practice that carries a lot of benefits, yet its adoption rate is very low because of the socio-cultural attitudes, comprehensive policy support, poor extension services, and limited access to markets. Farmers very often have no choice but to stick to traditional agricultural practices, and their knowledge about the advantages of diversification is very limited. In addition, the presence of ineffective incentives and underdeveloped supply chains considerably reduces the motivation of farmers to abandon monocultures even more. All these barriers combined are really hard to overcome and make the implementation of diversification strategies very limited.
Research gap:
The challenges of adoption are not often approached from a holistic perspective that integrates socio-cultural, policy, and market factors. Most of the relevant literature includes studies that scrutinise these barriers separately; thus, the result is a disjointed understanding of the issue. Another important point is that very little evidence is provided about how the targeted interventions, e.g., improvement of extension programs or market development, can actually make a difference to support diversification. A more comprehensive, based on solid evidence model would be needed to direct policy and practice.
Research Question:
What steps should be taken in order to create a multi-dimensional framework that allows for evaluating the effectiveness of policies, improving market access, and creating solid methods of measuring ecosystem services that would finally bolster diverse agri-food systems?
Outcome:
By means of the framework combining policy, market, and ecosystem services thoroughly, the research will provide us with the metrics for the policy impact that have been validated, the new models for the supply chain that are more efficient, and the environmental service measuring tools that are technology-based and support agricultural diversity that is resilient and sustainable.

Proposed PhD Title 3. Quantifying the Impact of Seasonal Ruminant Nutritional Feed Gaps on Human Food Security in Southern Africa
As indicated by Cooke et al. (2025), crop feed gaps resulting from seasonal variations have a significant negative effect on the productivity of ruminants and the food security of households in Southern Africa. The problem has been acknowledged, but the exact effect of these nutritional gaps on human populations is still unquantified to a large extent. The authors note that data are scarce concerning the quantity and quality of forage, micronutrient composition, and proteins, and that some of the most critical regions, like Angola, Eswatini, and Lesotho, are not properly covered in studies. Also, variations in research methods and a lack of insights into market dynamics are some of the factors that are making it difficult to come up with effective strategies to mitigate food insecurity related to feed.
Problem Statement:
Livestock productivity is greatly impacted by seasonal variations in ruminant feed that, in turn, can jeopardise nutrition and farmers’ incomes or even their whole households. Farmers and policymakers do not have sufficient data to determine where and when to apply their interventions based on continuous, long-term, area-specific, and interdisciplinary research. The lack of both good-quality forage data and regional studies, as well as the non-existence of market influences, has left the whole human food security system exposed to the vulnerabilities created by these nutrient-depleted feeds.
Research Gap:
The present literature does not provide an integrated, long-term evaluation of seasonal ruminant feed variations and their impacts on human food security. The majority of the studies mainly examine either forage quantity or quality and thus largely overlook micronutrient and protein composition, while also underrepresenting countries such as Angola, Eswatini, and Lesotho. In addition, the inconsistently sampled areas and the limited comprehension of market interactions are the other factors that prevent effective mitigation strategies from being developed.
Research Question:
In Southern Africa, how does the seasonal change of the ruminant feed accessibility and its quality influence human food security, and what are the measures that can be taken to fill the nutritional feed gap effectively?
Outcome:
The point of this research is to provide a complete understanding of the interrelation of seasonal feed shortages for ruminants and human food security. It will draw the picture of ruminants’ feed shortage by giving information about pasture quantity, quality, and mineral content for particular areas, as well as identifying the most important socio-economic and market factors that are influencing the gaps.

Proposed PhD Title 4. Building Resilient Agri-Food Systems: A Framework for Policy Effectiveness, Market Access, and Ecosystem Service Measurement in Crop Diversification
Eisert and Preskill contend that the verifications of advantage in the case of the present quantum algorithms—especially the variational and heuristic methods—are nonexistent, as classical algorithms typically match or outperform current quantum simulations. They suggest that the field requires stringent benchmarks and validation tools that could demonstrate a particular problem is quantumly easy, classically hard, and practically relevant at the same time. Advances in classical computing will be a major obstacle for the development of new reliable benchmarks and verification protocols that will address this gap between proofs of quantum advantage and the standard requirements.
Problem Statement:
Crop diversification, which offers both ecological and economic benefits, is still not practised because of socio-cultural attitudes, poor policy frameworks, lack of extension services, and market access issues. Sometimes, farmers depend on a single crop due to the poor education factor, lack of incentives, and poorly developed supply chain, which hinders the adoption of diversification strategies on a large scale.
Research gap:
The barriers to adoption are seldom approached in a comprehensive manner in the current research, as it is usually focused on one of the three challenges: policy, socio-cultural or market. Additionally, there is scant evidence available to support the view that the targeted interventions, such as improved extension programs or market development, influence the farmers’ decisions towards adopting diversified cropping systems.
Research Question:
In what ways can a multi-faceted framework that encapsulates policy effectiveness, market access, and ecosystem service measurement, etc., and thus become a major catalyst for the adoption and sustainability of crop diversification practices?
Outcome:
The project will be generating a well-rounded framework that incorporates policy, market access, and ecosystem service valuation altogether. It will give a set of measures for the impact of the policy, the models of the supply chain that are the most efficient, and the instruments for the evaluation of the environmental benefits that are validated. The ultimate goal of the research is to back up the development of resilient, sustainable, and economically viable strategies of crop diversification that will ultimately strengthen agri-food systems.

Proposed PhD Title 5. Integrating Food Security into Healthcare Systems: Developing a Culturally Adaptable, Economically Viable, and Technology-Enabled Framework for Improved Health Outcomes
The benefits of food security interventions in terms of health outcomes, like nutrition and chronic disease management, have been a subject of discussion, but their long-term effects are still not thoroughly examined. Tohit, Mat Ya, and Haque (2025) pointed out that the literature very seldom focuses on factors like sustainability, cultural adaptability, or economic effectiveness. Apart from that, there are also no studies bringing together comparisons about the adoption of technologies in different healthcare settings (e.g., hospitals, primary care, and community centres), and such studies also rarely look at the barriers that might hinder technology acceptance. Hence, these limitations restrict the creation of evidence-based, scalable, and sustainable programs. It is necessary to tackle the mentioned issues to come up with interventions that are suitable for the respective culture, economical in terms of costs, and that can provide health outcomes in terms of nutritional status and chronic diseases management with measurable improvements over time.
Problem Statement:
Food security programs are gradually getting the recognition they deserve as key components in the improvement of health outcomes; nevertheless, there are still no organised frameworks in the healthcare systems for the proper and effective integration of these programs. There has been a record of short-term advantages, but the sustainability of the program is still facing challenges, such as designing long-term impacts, culturally appropriate program designs, economic viability, and the adoption of technology.
Research gap:
The existing literature does not offer researchers a comprehensive model that takes into account all long-term outcomes, cultural relevance, comparative integration models, economic evaluation, and technology utilisation in the process of integrating food security into healthcare. The absence of such evidence stops healthcare providers and policymakers from being able to create interventions that are effective, sustainable, and scalable.
Research Question:
Which measures should be taken up to create an integrated healthcare system for food security that is acceptable from the cultural point of view, economically viable, technologically manageable, and has a long-term positive impact on health outcomes?
Outcome:
This study aims to produce a thorough plan that would permit the merging of the food security schemes with the healthcare systems. The proposal will include the application of cultural methods, the evaluation of the cost-effectiveness, the development of integration models that would be applicable in various healthcare settings, and the offering of technology-based solutions that would both increase accessibility and improve health outcomes, among other things.
