Large agricultural investments in Kenya’s Nanyuki Area: Inventory and analysis of business models

Many experts agree that more agricultural investment is needed in the global South to improve local food security and reduce poverty. However, there is a lack of consensus about the types of investment needed to achieve these goals. This paper contributes to the literature on large agricultural investments and corresponding business models by inventorying and analysing such investments in Kenya’s Nanyuki area. We identify four clusters of business models that differ primarily by type of production and other distinct determinants, namely: demand from markets; access to land; land tenure regime and colonial history; actors involved; biophysical context; labour availability; and governance of the value chain via private standards. The study results shed light on the factors that help or hinder implementation of large agricultural investments and shape their impacts in the context of African land use systems. The way land is accessed represents one of the most-decisive factors determining the risks and opportunities associated with such projects. We find that most investments in the Nanyuki area occur on land bought or leased from private owners.     

Women’s agricultural work and nutrition in South Asia: From pathways to a cross-disciplinary,grounded analytical framework

In this systematic review, we aim to examine the impact of women’s work in agriculture on maternal and child nutrition in South Asia. Building on previous reviews supported under the Leveraging Agriculture for Nutrition in South Asia (LANSA) consortium, and recent published literature, we include findings from new LANSA research. While mapping literature onto the gender-nutrition pathways linking agriculture to nutrition (Kadiyala et al., 2014), we also point to conceptual and methodological directions for further exploration emerging from our work. Key amongst these are a focus on seasonality, poverty, and gender relations, moving beyond both an exclusive focus on women as a unified and homogenous group, and agriculture as an unchanging and common set of activities and production processes. Our analysis suggests the need for a more contextualised approach, and for a richer cross-disciplinary framework for effectively addressing the ways in which women’s work mediates agriculture’s role in improving child and maternal nutrition in South Asia.

Renters,landlords, and farmland stewardship

Are farmers better stewards of the land they own than the land they rent from others? We answer this question using a data set that identifies Ontario farmers’ conservation practices on their own land as well as the land they rent. Using a fixed‐effects regression approach, we find that the role of tenure varies for different types of conservation practices. Farmers were found to be just as likely to adopt a machinery‐related practice such as conservation tillage on their rented land as that land which they own. On the other hand, farmers were found to be less likely to adopt site‐specific conservation practices such as planting cover crops on rented land. However, this effect diminishes as the expected length of the rental relationship increases when the landlord has a farming background.     

Efficiency and equity of rural land markets and the impact on income: Evidence in Kenya and Uganda from 2003 to 2015

This study examines the evolution of land sales and rental markets and their impact on agricultural efficiency in rural Kenya and Uganda using panel data spanning over 10 years. Both countries show that land markets induce efficiency by transferring land to households with higher farming ability. In both countries, land markets enhance equity by transferring land from land-abundant to land-constrained households. Although renting in land increases crop income in Kenya, we find no evidence that it enables households to escape from poverty. In contrast, increase in owned land helped decrease poverty in Uganda. Parcel-level analysis reveals that rented-in land and owned land differ in productivity levels and crop choice. These findings point to the potential weaknesses in the land markets in Kenya and Uganda that impede their ability to contribute to poverty alleviation.     

上海合作组织命运共同体:一项研究议题

构建上海合作组织命运共同体是中国政府提出的关于促进上海合作组织长远发展的重大倡议。由于上海合作组织命运共同体理念的提出时日尚短,学术界关于该理念的研究尚未全面启动。要使上海合作组织命运共同体理念成为一个有效的研究议题,不仅需要明晰上海合作组织命运共同体的具体内涵,而且需要将其纳入国际共同体、国际组织和大国外交等议题的研究,提炼出一些具有普遍性的理论命题。就攸关上海合作组织命运共同体构建的重大问题而言,至少需要回答上海合作组织命运共同体提出的理论与实践意义、上海合作组织命运共同体构建应遵循的基本路径、上海合作组织命运共同体构建的基础和条件、上海合作组织命运共同体构建面临的挑战与障碍、学术界能为上海合作组织命运共同体构建提供的对策建议等重大问题。在此过程中,学术界还需将其与周边命运共同体、人类命运共同体等家族相似性的概念纳入同一研究视域,以澄清上海合作组织命运共同体的内涵与外延,辨识上海合作组织命运共同体演变的动力与机制,并从理论层面提炼上海合作组织发展经验的特殊性与普遍性。     

Capitalization of land development rights in rural China: A choice experiment on individuals’ preferences in peri-urban Shanghai

The capitalization of land development rights is acknowledged as the key to improving compensations for rural landholders and ameliorating land-related social conflicts in peri-urban China. Investigations into reasonable as well as feasible compensation standards and the capitalization mechanism are yet to be done. This study uses a survey-based choice experiment to empirically estimate the value of land development rights in peri-urban Shanghai for three forms of rural land conversion – acquisition, consolidation and (informal) sale. The results show that heterogeneity across individuals’ preferences translates into different utilities from land development, which affects individual’s willingness to participate in this process. This effect is found to be the strongest for land sales on the informal market. If, however, land conversion is managed by local governments and rural collectives, the expected utilities of individuals have no significant effect on the amount of land development. The results suggest that capitalizing land development rights under consideration of land attributes and individuals’ preferences would lift compensation standard to a level that strikes a balance among competing land-related interests. In addition, it would promote China’s land development by bypassing the institutional constraints imposed by the current land tenure system.     

Women’s empowerment boosts the gains in dietary diversity from agricultural technology adoption in rural Kenya

Using new survey data from rural Kenya, this paper assesses the moderating effect of women’s empowerment on the relationship between agricultural technology adoption and women’s dietary diversity. We use a multiple treatment endogenous switching regression framework to control for potential endogeneity of women’s empowerment and technology adoption. We find that women’s empowerment has a positive and significant effect on the women’s dietary diversity score regardless of technology adoption status. We further show that women’s empowerment enhances the positive effects of technology adoption on women’s dietary diversity. Although technology adoption has a positive impact on women’s dietary diversity regardless of empowerment status, its effect is stronger for households with empowered vs. disempowered women. Study results suggest that individual and household welfare could be enhanced to a greater degree through interventions that promote women’s empowerment and technology adoption simultaneously rather than separately.
