AbstractFrom a qualitative study of sugarcane production in Chemelil(western Kenya) and insights drawn from the Kenyan land reform enacted in 2012, this study contends that the goal of land reform to provide farmers with certainty of rights to land to invest in and benefit from agriculture is heavily weakened by the farmers’ lack of control over agricultural inputs. Land reform and intensive agriculture, such as sugarcane production, share the same market-based land discourse, where land is considered an environmental asset to be harnessed efficiently for high productivity. Although this discourse supports the application of high inputs for maximum agricultural outputs, it has also eroded farmers’ power and control over their lands. This loss of power and control occurs through the supply of high-cost agricultural inputs from external sources, such as state research agencies and the Chemelil Sugar Company. The control of inputs by sources external to farmers stifles possible farm-based innovations that could reduce farming costs. The chapter, thus, contends that, although land reform aims at farmers’ utmost benefit from land, the farmer’s lack of control over agricultural inputs limits the benefits they derive from land use for intensive agriculture; this is especially true in the case of small-scale farmers.

Incandescent Lamps

Light traps using incandescent lamps operated on 115-volt commercial power have been used in studies in Saskatchewan of the lepidopterous pests of rapeseed crops. However, there was a need for a light trap that could be operated in areas remote from electric power. Because of the proven usefulness of low-wattage argon lamps in pink bollworm detection investigations (Glick 1961), and their low power requirements, these lamps were used experimentally in the portable power and control system described here.

Remarkable Progress

Flying insects exhibit truly remarkable capabilities. There has been significant interest in developing small-scale flying robots by taking inspiration from flying insects. The paper by Helbling and Wood reports remarkable progress made by the research community in realizing insect-scale flapping wing vehicles and identifies research challenges and opportunities. This discussion builds upon their paper and examines the potential of insect-scale flapping wing flight from an application point of view. It summarizes requirements and mention implications of these requirements on propulsion, power, and control architecture.

Flying insects are able to navigate complex and highly dynamic environments, can rapidly change their flight speeds and directions, are robust to environmental disturbances, and are capable of long migratory flights. However, flying robots at similar scales have not yet demonstrated these characteristics autonomously. Recent advances in mesoscale manufacturing, novel actuation, control, and custom integrated circuit (IC) design have enabled the design of insect-scale flapping wing micro air vehicles (MAVs). However, there remain numerous constraints to component technologies—for example, scalable high-energy density power storage—that limit their functionality. This paper highlights the recent developments in the design of small-scale flapping wing MAVs, specifically discussing the various power and actuation technologies selected at various vehicle scales as well as the control architecture and avionics onboard the vehicle. We also outline the challenges associated with creating an integrated insect-scale flapping wing MAV.
