- 16pgs, Humanity's growing appetites for food and energy are placing unprecedented yield targets on our lands. Chasing those ever-expanding land intensification targets gave rise to monocultures and sharpened the divide between food and energy production groups. Here, we argue that this does not have to be a zero-sum game if food and energy can be co-generated in the same land. Co-generation can lead to sustainable intensification but requires a paradigm shift in the way we manage our resources, particularly light. Using an extended model of plant photosynthesis and transpiration, we demonstrate how plants react to different incident light spectra and show that manipulating light could be effective for boosting land and water efficiencies, thus potentially improving soil health. This knowledge can possibly unlock the real potential of promising modern agricultural technologies that target optimization of light allocations such as agrivoltaics. This study suggests that the blue part of the light spectrum is less efficient in terms of carbon assimilation and water use and could be more effectively used to produce solar energy, while the red part could efficiently produce biomass. A sensitivity analysis to the most important crop and environmental variables (irradiance, air temperature, humidity, and CO2 concentration) shows that plant response to different light treatments is sensitive to environmental boundary conditions and is species-specific. Therefore, further research is necessary to assess which crops and climates are more suitable to optimize the proposed food-water-energy nexus.

- 9 pages, Despite agriculture’s great potential to Tanzania agricultural development, the sector faces diverse challenges. For example, existence of gender gaps in accessing agricultural production resources and benefits obtained from the same impede the sector’s growth. Therefore, adoption of conservation agriculture (CA) has been seen as one of the measures to address the sector limited productivity. Nonetheless, there is limited knowledge on how CA has managed to reduce gender inequalities in accessing both reproductive resources and benefits accrued from agriculture. This paper examines gender gaps in conservation agriculture programme implemented by Sustainable Agriculture in Tanzania (SAT), by specifically analyzing gender participation and relations in CA in Morogoro municipality and Morogoro district. This study adopted a mixed method approach whereby both qualitative and quantitative data were collected from four sites where SAT implements its activities. Findings show that CA has significantly reduced gander gaps in accessing production resources and services as well as raising women’s participation in decision making with regards to production and use of income obtained from sales of produce. Farmers regardless of the gender can access extension services, and credit, and are involved in various initiatives collectively. Despite the economic benefits, findings show that CA is laborious and takes much of farmers’ time, women being more affected. Therefore, it is recommended that the central and local governments and various stakeholders should promote the spread of conservation agriculture technologies since it reduces the biasness in agriculture and empowering women. Ensuring access to advanced cheap technologies to farmers. Nonetheless, there is need to ensure that female farmers are not overburdened in the process.

- 14 pages, As agricultural conservation priorities evolve to address new complex social-ecological problems and emerging social priorities, new conservation incentive program participation and success can be enhanced by incorporating local stakeholder preferences into program design. Our research explores how farmers incorporate ecosystem services into management decisions, their willingness to participate in payment for ecosystem services programs, and factors beyond compensation level that would influence participation. We conducted three focus groups with 24 participants between January of 2019 and May of 2019 in Vermont. Our study revealed that a strong, intrinsic stewardship ethic motivates farmers to enhance ecosystem service provisioning from their farms, though financial pressures often limit decision-making. These results suggest that programs with sufficient levels of payment may attract participation, at least among some types of farmers, to enhance ecosystem services from farms in Vermont. However, farmers may be deterred from participating by perceived unfairness and distrust of the government based on previous experiences with regulations and conservation incentive structures. Farmers also expressed distrust of information about ecosystem services supply that conflicts with their perceptions of agroecosystem functioning, unless delivered by trusted individuals from the extension system. The delivery of context-specific information on how management changes impact ecosystem service performance from trusted sources could enhance farmers’ decisions, and would aptly complement payments. Additionally, farmers expressed a desire to see a program that both achieves additionality and rewards farms who have been stewards, goals that are potentially at odds. Our findings offer important insights for policy makers and program administrators who need to understand factors that will influence farmers’ willingness to participate in payment for ecosystem service programs and other conservation practice adoption initiatives, in Vermont and elsewhere.
