- ItemA novel modelling toolkit for unpacking the Water-Energy-Food-Environment (WEFE) nexus of agricultural development(2022) Correa Cano, M. E.; Salmoral, G.; Rey, D.; Knox, J. W.; Graves, A.; Melo Contreras, Óscar; Foster Bonnette, William; Naranjo, L.; Zegarra, E.; Johnson, C.; Viteri Salazar, O.; Yan, X.Increasing food demand has led to significant agricultural expansion globally with negative impacts on resources and the environment, a perfect manifestation of the Water-Energy-Food-Environment nexus. Whilst many tools have been developed to understand the complexity of the Water-Energy-Food-Environment nexus most have failed to explicitly consider biophysical and socio-economic aspects simultaneously. A novel Water-Energy-Food-Environment modelling toolkit is developed that integrates both these components by combining different modelling approaches including irrigation simulation, economic modelling and life cycle environmental assessment. The toolkit is demonstrated using two major agro-export crops (asparagus and table grapes) in the Ica Valley, Peru, a severely water-stressed region. The toolkit was able to provide novel insights into the implications of different farming practices on resource efficiency at the field level in relation to water and energy, under contrasting future scenarios reflecting socio-economic outcomes at the local to regional levels (e.g., food prices, employment, and income) as well as environmental impacts at local to global scales. This information enables different stakeholders to better understand the interlinkages and inter-dependences between the Water-Energy-Food-Environment nexus elements and the complex impacts of agricultural expansion beyond the immediate sector and its geographical extent, helping decision makers design more coordinated agricultural policies and support sustainable agricultural transformation
- ItemAgricultural and Forestry Land and Labor Use under Long-Term Climate Change in Chile(2021) Melo Contreras, Óscar; Foster Bonnette, WilliamThe appropriate design of land-use and rural employment policies depends upon the anticipated performance of the farm sector in the context of expected climate changes, especially with respect to land allocations to potential activities. Concerns over the possible net benefits of land-use changes are particularly acute in lower- and middle-income countries, where agriculture tends to be important in employment, income generation and foreign-exchange earnings. This paper presents an analysis of the expected impacts on land use in Chile of projected climate-change scenarios in 2040 and 2070. We developed a farmland allocation model with associated labor employment at the municipal level driven by expected relative net incomes per hectare, constructed from local average per-hectare yields, regional average output prices and per-hectare production cost estimates. The sensitivities of cropland allocations to relative net-income changes were estimated using historical land allocations at the municipal level derived from the last two Chilean Agricultural Censuses. The results show that the impacts of climate changes will be mitigated by land-use adaptation, the main export-earning crops tending to move south; in aggregate, agricultural employment will decrease in all the climate-change scenarios; forestry and agriculture would likely suffer a loss in net-income generation under severe climate-change scenarios.

- ItemImpacto de la pandemia Covid 19 en la fuerza de trabajo agrícola: evidencia del caso chileno(2022) Guarda Hinostroza, Nicolás Eduardo; Foster Bonnette, William; Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería ForestalUna de las principales preocupaciones por parte de los diseñadores de política al momento de tomar medidas sanitarias en el contexto de la pandemia Covid 19 era posible impacto sobre la economía y el trabajo. Esta tesis busca aportar a la medición de dichos impactos, analizando lo sucedido en el caso de la fuerza de trabajo agrícola en Chile. Usualmente, se entiende a la agricultura como un sector de refugio económico, y por lo tanto es de utilidad también comprender si en esta oportunidad cumplió dicho rol. Se utiliza un modelo econométrico de tipo Autorregresión de Vector Panel (PVAR), en la cual se describe la oferta de trabajo de los hogares y se modela su trayectoria a lo largo del periodo 2019-2021. Por medio de la introducción de controles relacionados con la presencia de cuarentenas y la tasa de mortalidad comunal, se busca aislar los posibles impactos sobre el mercado laboral asociables directamente a la pandemia. Los resultados indican que mientras el resto de los sectores económicos se vieron afectados con una reducción en torno al 1,3% en la probabilidad de trabajar, tales efectos no se observan en el sector agropecuario. Esto puede interpretarse como una externalidad positiva asociada a la agricultura, por vía de mayor resistencia a este tipo de shocks externos, valorizada en aproximadamente 800 millones de pesos chilenos como cota inferior.
