The purpose of this paper is to analyze smallholder farmers’ perceptions of climate change and its adverse effects, identify major adaptation strategies used by farmers and analyze the factors that influence the choice of adaptation strategy by smallholder farmers in eastern Ethiopia.

The study was based on a cross-sectional survey of 296 sample households selected from three districts in east Ethiopia. Data were collected with the aid of a semi-structured questionnaire and review of literature, documents and databases.

The study provides empirical evidence that majority of farmers in the study area are aware of climate change patterns and their adverse effect on income, food security, diversity, forest resources, food prices and crop and livestock diseases. In response to these adverse effects, major adaptation strategies used by farmers include cultivating different crops, planting different crop varieties, changing planting dates, use of soil and water conservation techniques, conservation agriculture practices and engaging in non-farm income activities. Choice of adaptation strategies are influenced by gender of household head, household size, farm size, distance from market and number of farm plots.

The study suggests that developing more effective climate change adaptation strategies need support from the government. Such an effort needs provision of the necessary resources such as credit, information and extension services on climate change adaptation strategies and technologies, and investing in climate smart and resilient projects.

The study adopts multivariate probit model that models farmers’ simultaneous adaptation choice behavior which has been rarely addressed by previous researches.

The purpose of this study is to examine household food gap and food insecurity in Eastern Ethiopia. Differences in food gap and food insecurity were also examined in terms of gender of the household head and location.

A combination of quantitative and qualitative methods such as household survey, key informant interview and focused group discussion were utilized for this study. Households were drawn randomly from the study area.

In terms of food availability, more than half of the households experienced a food gap during the year, especially during the months of July and August. In terms of gender, female-headed households had more months of food shortage compared to their male counterparts. This disparity was also reflected in poorer food access among female-headed households as shown by the higher HFIAS. Differences in food insecurity were obtained in terms of gender of the household head and location. Livestock ownership, cereal crop production, extension contact and household size significantly influenced household food access.

Findings are valid only for low-land agroecologies

This study contributes to the existing literature by examining household food gap and food insecurity using a combination of quantitative and qualitative methods. It adds value in examining disparities between male-headed and female-headed households. Literature related to seasonal household food insecurity is limited in Ethiopia. This study contributes in this regard by examining seasonal food insecurity between post-harvest and pre-harvest seasons.

The world is facing serious global food security challenges such as the need for sufficient food for a growing population and an exponential growth in nutrient deficiency disorders. Agricultural biotechnology, such as genetically modified (GM) crops, offers itself as a promising solution to address one or more of these issues. Golden Rice (GR) is an example of a GM crop which contains high amount of β-carotene, a compound which is an antioxidant and a precursor of vitamin A. In spite of GR’s promised potential benefits in combating vitamin A deficiency (VAD) disorders it is still not cultivated. This viewpoint paper aims to present the reader with a need for multidisciplinary research agenda, the outcomes of which can contribute towards the acceptance of GR.

This viewpoint paper is based on an extensive literature review to identify the “gaps” which contributed to low acceptance of GR. This paper presents a systematic discussion on the importance of GR in tackling VAD and discusses controversies around GR and a scientific approach to tackle them.

The literature review clearly indicates that there is a huge gap in information substantiating the potential of GR for consumers as well as for the farming community. Addressing these issues can substantially increase the acceptance and cultivation of GR. This viewpoint paper proposes food technologists’ and social scientists’ research agenda for GR and further indicates how the involvement of other research disciplines can improve the acceptance of GR.

The literature review indicates the potential of GR in tackling VAD disorders but clearly lacks information to substantiate these arguments. This paper presents authors’ opinions, urging scientists to take up a multidisciplinary research approach to emancipate GR from the clutches of GM food controversies.

The purpose of this study is to establish household‐level food security risks associated with climate variation, and how households respond to these risks in a patriarchal society such as in Northern Cameroon where subsistence women producers have less control over resources required to support the food production sector which depends entirely on the quality of the rainy season.

Primary data from 116 female‐headed households (FHHs) and 184 male‐headed households (MHHs) is examined for the three Northern provinces of Cameroon. The survey generated information on the response and coping strategies to climatic variation; and the socioeconomic impacts of climate on households. The multinomial logit model is employed to establish the determinants of the choice selection for climate risk coping options by households.

Both FHHs and MHHs are exposed to stresses related to food production and availability, low incomes and food accessibility and utilization of food supplies, heightened by the real and perceived effects of the variability of current climate. Short‐term coping choices include diversification of livelihood which in turn impacts food accessibility and consumption choices.

A seasonal pattern is revealed in household expenditure with households spending more than 70 percent of their income on food in spring. The lowest food expenditures are in summer. Market and income manipulation choices for food supply stability include a range of non‐farm income generation strategies to cope with expected shortages induced by climatic variability. The current climate variation, household demography, and farming conditions via access to credit, tenure, and extension service delivery are significant determinants of coping choices for households perceiving change in climatic patterns.

Significant seasonal patterns in household food availability, accessibility and utilization are observed with important implications for both household welfare and as precursor to long‐term adaptation to climate change.

This study investigates implications of crop and income diversifications on consumption expenditure (welfare) of rice-producing households in Ghana. It further compares diversification by three rice production systems: two-season rain-fed, two-season irrigated and one-season rain-fed rice production.

Primary data were sourced from 225 rice farmers. Margalef index and three-stage least-squares were employed.

Majority of rice-farming households in Ghana diversify livelihoods. The extent of livelihood diversification differs among two-season rain-fed, two-season irrigated and one-season rain-fed rice-producing households. Credit, distance to district capitals, production purpose and number of farming seasons influence crop and income diversifications, and consumption expenditure of rice-producing households. While crop diversification reduces consumption expenditure, income diversification increases it. Crop and income diversifications positively influence each other. Consumption expenditure reduces crop diversification but increases income diversification.

Policy should be directed towards the promotion of more livelihood activities to boost rice farmers' welfare. There should be awareness creation and training programmes to enable rice farmers realize different economic activities within and outside the agricultural value chain.

Crop and income diversifications were measured as continuous response variables, unlike previous studies that used a binary response variable. The authors established a synergy among crop and income diversifications, and consumption expenditure (welfare). The authors further compared crop and income diversifications by three rice production systems: two-season rain-fed, two-season irrigated and one-season rain-fed rice production systems.

The purpose of this paper is to explore the availability and use status of plant species and their genetic diversities from local forests and uncultivated lands in the context of three different Chepang ethnic communities of Nepal. In the current context of increased threats upon the natural resources to meet increased food demand, unsustainable harvest is also practised, leading to unavailability of the diversities, thus conservation and sustainable harvest were compared along with contribution of those neglected and underutilized species for food, nutrition and livelihood security of the local dwellers.

This research was done by using multi-stage random sampling of 15 households from each village development committee (VDC), namely Shaktikhor, Kaule and Siddhi of Chitwan district of Nepal. The farmers’ participation in this study was ensured through participatory research methods, including group discussions (GD) and other Participatory Rural Appraisal (PRA) tools. In addition, field observations, household interviews and consultation with experts were used in this study.

The Chepang community was found to possess immense knowledge on forest products and crop landraces and utilize the various plants for food and medicine. The underutilized species were used by the local people in different forms (food, vegetables, medicine, and for cultural and economical reasons). The uses of 46 underutilized plant species were documented, including 25 species with multiple functions as food, vegetables, and medicines. The overall contribution was about 2.7 months a year, with a significant difference between Siddhi (3.8months), Shaktikhor (2.4 months) and Kaule (1.9 months).

This research was an exploratory action research covering only 45 households from three VDCs and is not an adequate sample size considering population size. Due to differences in the altitude, farm and family size, level of education, the number of species availability and uses may differ and this research needs to be replicated covering different seasons, years and more respondents.

This piece of research is original and conducted by three researchers working with different institutions. This strongly showed a gradual loss of the plant genetic diversities due to inability of the state, through its policy and programs, to recognize the contribution of those species in food, nutrition and livelihood security of vulnerable populations. The state should emphasize on research, education and technology development for those undermined crops, despite their huge contribution to the livelihood system.

Climate change and its imminent threat to human survival adversely impact the agriculture sector. In an impoverished country like The Gambia, economic costs of climate change are colossal. This study aims to establish a computable general equilibrium (CGE) model for The Gambia’s agriculture sector to examine the effects of climate change on crops, livestock and sea-level rise.

This study used a CGE model with other climate change impact models to compute the impacts of climate change on The Gambia’s agriculture sector. The social accounting matrix calibrates the results from the various models, thereby generating the baseline results which exemplify a “steady-state” and policy shock results illustrating the medium- and long-term effects of climate change on the country’s agriculture sector.

The baseline results indicate the status quo showing the neglect of the agriculture sector due to limited investment in the sector. Hence, the sector is the “hardest hit” sector as a result of climate change. When the model factored in climate change in the medium term (2055) and long term (2085), the macroeconomic indicators of gross domestic product, national savings, wages, disposable income and consumer price index deteriorated, elucidating the vulnerability of the economy to climate change. The consumption of groundnuts, cattle and fish will decline by 5%, 5% and 4%, respectively, in the long term. However, the production of all agricultural commodities will decline by an average of 35% for the same period. The results for international trade show that exportation would decline while importation will increase over time. The general price level for agricultural commodities would increase by 3% in 2055 and 5% in 2085. Generally, the results manifest the severity of climate change in the agriculture sector which will have a multiplier effect on the economy. The impact of climate change would result in agriculture and economic decline causing hunger, poverty and human misery.

The caveat of this study revealed the nuances not captured by previous Gambian climate change studies, thus the novelty of the study.

In many societies, conflicts of violent nature regularly spring up that usually cause a destruction of economic and social assets and needless loss of human lives. Violent conflicts and food entitlements seem to bear mutual feedbacks: first and foremost, as violent conflicts result in destruction of economic assets, conflicts usually tell upon the cultivation of foods, procurement and storage of foods and also the distribution and marketing of foods. The disruption in the agrarian sector can lead to serious decline in food availability and consequent famines, which can exacerbate and fuel further conflicts. On the other hand, the distribution and availability of foods can trigger violent conflicts in backward societies as a means to acquire and retain food entitlements, which can in turn jeopardise the agrarian equilibrium. Thus, the relationship between food entitlements and conflicts are a double-edged sword that can lend precarious instability to a backward society. During the last five decades, governments in developing nations have kept a close vigil on their agrarian sector, yet there is a clear indication in the global economy that warns of a looming food crisis, especially in the poorer regions of our globe. Food crises can seriously challenge global peace. Conflicts and hunger are hence complex phenomena. This chapter provides a comprehensive, and possibly the first, study of the economics of food entitlements and potential threats of conflicts in the current conjuncture.

The purpose of this paper is to analyze how farmers are reducing vulnerability of rain‐fed agriculture to drought through indigenous knowledge systems (IKS) in the Atankwidi basin, north‐eastern Ghana.

This paper draws on combined qualitative and quantitative research methods and data. First, the paper draws on qualitative data generated from in‐depth interviews and focus group discussions from purposively sampled farmers in the Atankwidi basin. It also draws on a survey conducted on 131 systematically and randomly sampled households in three communities of the basin, namely Yua, Pungu and Mirigu.

The results show that farmers are planting multiple indigenous drought resilient crop varieties and employing different rounds of seeding and or staggering planting between multiple farms. They are also applying indigenous forms of organic manure, checking soil erosion through grass strips and stone terracing and adopting paddy farming for improving soil and water conservation towards enhancing plant adaptation to drought. The paper therefore, asserts that through conscientious effort, farmers are reducing vulnerability of rain‐fed agriculture to drought through indigenous knowledge systems of drought risk management.

The paper recommends that capacity for managing vulnerability to drought at the local level, including the Atankwidi basin, can be enhanced by incorporating IKS into District Development Planning (DDP) and giving priority to the strategic role of IKS in climate change adaptation planning.

This paper fulfills a need for researching the relevance of IKS for reducing vulnerability of rain‐fed agriculture to drought in particular, and enhancing adaptation to climate change in general in the quest for promoting Endogenous Development (ED) in Africa.

The widespread introduction of genetically modified (GM) crops may change the effect of agriculture on the environment. The magnitude and direction of expected effects are still being hotly debated, and the interests served in this discussion arena are often far from those of science and social welfare maximization. This chapter proposes that GM crops have net positive environmental effects, while regulatory responses focus mainly on environmental concerns, giving an unbalanced picture of the regulatory context. This unbalance supports the hypothesis that environmental concerns about GM crops have been politically instrumentalized and that more attention should be paid to regulatory responses considering the environmental benefits of this technology. It is also argued that a number of environmental effects have not yet been quantified and more research is needed in this direction.
