This chapter examines how Maragoli women farmers’ plot-level crop control, individual, and household variables affect yields. This chapter contributes to a holistic understanding of the ramifications of quantitative and qualitative factors informing women farmers’ plot-level undertakings and yields as well as their innovative and creative strategies for optimizing output. It broadens the existing debate in the sub-Saharan African agricultural production literature by suggesting a composite measure of plot-level crop control as one factor influencing women farmers’ yields even in situations where land is owned by someone else. It also provides a rich discussion of the various and interlocking qualitative factors distorting women farmers’ incentive structures, efforts to increase plot-level yields and their strategies for minimizing the detrimental effects of the same.

A multimethod quantitative and qualitative ethnographic case study approach was used in this study.

This chapter demonstrates that women strategically bargained and invested more of their productive resources on the plots where they anticipated the greatest individual gains.

This chapter underscores women farmers’ ability to boost agricultural output when there are appropriate incentives for them to do so and suggests the theoretical and practical relevance of secure control and property rights over the products of the land not for the household (head), but for the cultivator. The chapter demonstrates and reaffirms that Africa women farmers respond appropriately to incentives and suggests that there is need for a customized, renewed, and sustained emphasis on women farmers’ empowerment and inclusion in all levels in the agricultural sector in order to actualize increased yields. Investing in women farmers and implementing policies that narrow existing gender disparities in African agricultural production systems is holistically beneficial.

In The Changing Body (Cambridge University Press and NBER, 2011), we presented a series of estimates showing the number of calories available for human consumption in England and Wales at various points in time between 1700 and 1909/1913. We now seek to correct an error in our original figures and to compare the corrected figures with those published by a range of other authors. We also include new estimates showing the calorific value of meat and grains imported from Ireland. Disagreements with other authors reflect differences over a number of issues, including the amount of land under cultivation, the extraction and wastage rates for cereals and pulses and the number of animals supplying meat and dairy products. We consider recent attempts to achieve a compromise between these estimates and challenge claims that there was a dramatic reduction in either food availability or the average height of birth cohorts in the late-eighteenth century.

World agriculture faces enormous challenges in the coming decades. To feed the world adequately in 2050, agricultural production in developing economies will need to nearly double. Incremental production will mainly come from increases in yields or cropping intensities. This chapter focuses on the potential of genetically modified (GM) crops to contribute to agricultural productivity growth and poverty reduction in developing economies. On the basis of a comprehensive literature review of the most recent literature, we aim to shed light on (a) whether GM crops benefit farmers in developing economies and (b) whether GM crops that are currently in the research pipeline address future challenges for agriculture. The first part of the chapter reviews farm-level impacts of GM crops in developing economies. The second part discusses the GM crop research pipeline. GM crop markets are expected to grow in the future but not to change dramatically. We conclude that GM crops benefited farmers, including resource-poor farmers, in developing economies, but benefits are location- and individual-specific. Addressing such complexities will be required to unlock technology potentials.

Agricultural production in Honduras was devastated by the impact of hurricanes Eta and Iota in November 2020, placing people depending on agriculture in a vulnerable and food insecure situation. In addition to the COVID-19 pandemic and the economic downturn in the country, these extreme events are forcing more people to leave and head to North America in migrant caravans. Over the last decades, Honduras has been impacted by severe climate change events, including droughts and extreme tropical storms. According to the Global Climate Risk Index (CRI), developed by Germanwatch (Eckstein et al., 2019), Honduras was the second most affected country by climate change over a period of 20 years, from 1998 to 2017. Extreme rainfall and tropical storms, droughts, variation in rainfall patterns, and soil loss make agriculture more difficult, thus placing low-income rural families at the edge of hunger and food insecurity. In terms of migration policy, much focus has been given to economic instability, weak governance, violence and crime as push factors for migration, but the effect of food insecurity and climate change impact is often overlooked in this narrative. Agricultural areas in Honduras, traditionally the backbone of food production, have been identified as climate out-migration hotspots. The purpose of this chapter is to examine the most relevant data to understand the interactions between climate change, food insecurity and the current migration crisis in Honduras.

The products of transgenic technology have captured the attention of enthusiasts and detractors, but transgenics are just one tool of agricultural biotechnology. Other applications enable scientists to understand biodiversity, to track genes through generations in breeding programs, and to move genes among closely related as well as unrelated organisms. These applications all have the potential to lead to substantial productivity gains.

In this chapter we provide an introduction to basic plant genetic concepts, defining molecular markers, transgenic and cisgenic techniques. We briefly summarize the status of commercialized biotechnology applications to agriculture. We consider the likely future commercialization of products like drought tolerant crops, crops designed to improve human nutrition, pharmaceuticals from transgenic plants, biofuels, and crops for environmental remediation. We identify genomic selection as a potentially powerful new technique and conclude with our reflections on the state of agricultural biotechnology.

Research at universities and other public-sector institutions, largely focused on advancing knowledge, has aroused enormous optimism about the promise of these DNA-based technologies. This in turn has led to large private-sector investments on maize, soybean, canola, and cotton, with wide adoption of the research products in about eight countries. Much has been made of the potential of biotechnology to address food needs in the low-income countries, and China, India, and Brazil have large public DNA-based crop variety development efforts. But other lower income developing countries have little capability to use these tools, even the most straightforward marker applications. Ensuring that these and other applications of biotechnology lead to products that are well adapted to local agriculture requires adaptive research capacity that is lacking in the lowest income, most food-insecure nations. We are less optimistic than many others that private research will fund these needs.

Malnutrition is widespread and affects about one-third of humanity. Increasing production and consumption of vegetables is an obvious pathway to improve dietary diversity, nutrition and health. This chapter analyses how climate change is affecting vegetable production, with a special focus on the spread of insect pests and diseases. A thorough literature review was undertaken to assess current global vegetable production, the factors that affect the spread of diseases and insect pests, the implications caused by climate change, and how some of these constraints can be overcome. This study found that climate change combined with globalization, increased human mobility, and pathogen and vector evolution has increased the spread of invasive plant pathogens and other species with high fertility and dispersal. The ability to transfer genes from wild relatives into cultivated elite varieties accelerates the development of novel vegetable varieties. World Vegetable Center breeders have embarked on breeding for multiple disease resistance against a few important pathogens of global relevance and with large evolutionary potential, such as chili anthracnose and tomato bacterial wilt. The practical implications of this are that agronomic practices that enhance microbial diversity may suppress emerging plant pathogens through biological control. Grafting can effectively control soil-borne diseases and overcome abiotic stress. Biopesticides and natural enemies either alone or in combination can play a significant role in sustainable pathogen and insect pest management in vegetable production system. This chapter highlights the importance of integrated disease and pest management and the use of diverse production systems for enhanced resilience and sustainability of highly vulnerable, uniform cropping systems.

In this paper I explore how members of rural Maya households in central Quintana Roo (Mexico) interact with the wider social system and cope with long-term transformations in productive relations since c. 1840. Maya householders integrate elements of capitalist and non-capitalist modes of production. Through particular cultural forms they regulate internal uses of wealth and their relationships with the larger capitalist world. Social and economic stratification is a fundamental feature of life among Maya householders today as it was in the past. While disparities between wealth strata within the local context have increased, the community is far from disintegrating into antagonistic groups.
