Simple Equations

Abstract. It is clear from Lhomme et al. (2014) that aspects of the explanation of the Matt–Shuttleworth approach can generate confusion. Presumably this is because the description in Shuttleworth (2006) was not sufficiently explicit and simple. This paper explains the logic behind the Matt–Shuttleworth approach clearly, simply and concisely. It shows how the Matt–Shuttleworth can be implemented using a few simple equations and provides access to ancillary calculation resources that can be used for such implementation. If the crop water requirement community decided that it is preferable to use the Penman–Monteith equation to estimate crop water requirements directly for all crops, the United Nations Food and Agriculture Organization could now update Irrigation and Drainage Paper 56 using the Matt–Shuttleworth approach by deriving tabulated values of surface resistance from Table 12 of Allen et al. (1998), with the estimation of crop evaporation then being directly made in a one-step calculation using an equation similar to that already recommended by the United Nations Food and Agriculture Organization for calculating reference crop evaporation.

Tree Approach

The United Nations Food and Agriculture Organization (FAO) has established the Water-Energy-Food Nexus, implying that the three commodities are inextricably linked forming a complex system of interrelations. Perceiving water, energy and food as a system variable with dependencies rather than a singularity suggests an approach of a more holistic view that can offer a sustainable plan for managing resources. In this article, the already established three-way Nexus is expanded to include two more dimensions, namely land use and climate and a framework for modelling the interlinkages among these dimensions is presented.

<P class=abstract>This article introduces the work of the United Nations Food and Agriculture Organization (FAO), and describes its interest in the application of distance learning strategies pertinent to the challenges of food security and rural development around the world. The article briefly reviews pertinent examples of distance learning, both from the experience of FAO and elsewhere, and summarises a complex debate about the potential of distance learning in developing countries. The paper elaborates five practical suggestions for applying distance learning strategies to the challenges of food security and rural development. The purpose of publishing this article is both to disseminate our ideas about distance learning to interested professional and scholarly audiences around the world, and to seek feedback from those audiences.</P>
