[学术文献] Climate risk management strategies and food security: Evidence from Cambodian rice farmers 进入全文
This study investigates the adoption of three climate-resilient strategies (3CRS), drought/flood-resistant rice varieties, integrated pest management (IPM) practices, and weather advisory; the impact of 3CRS on food security, namely, productivity and profits of the Cambodian paddy farmers. Using endogenous switching regression (ESR) approach and household survey from Cambodian farmers, the study finds a low adoption rate (14%) of 3CRS. The low adoption of 3CRS means missing opportunities for rice farmers. Access to information through training and input suppliers is found to increase the adoption of 3CRS. The adoption of 3CRS increases rice yields and profits by 36% and 45%, respectively. Additionally, if nonadopters adopted 3CRS, rice yields and profits would increase by 55% and 52%, respectively. Findings suggest the development of institutional capacity, implementation, and dissemination of knowledge of climatic changes, and adaptation strategies to increase food security.
The Covid-19 pandemic has triggered the most severe recession in nearly a century and is causing enormous damage to people’s health, jobs and well-being, according to the OECD’s latest Economic Outlook. As restrictions begin to ease, the path to economic recovery remains highly uncertain and vulnerable to a second wave of infections. Strengthening healthcare systems and supporting people and businesses to help adapt to a post-Covid world will be crucial, it says. The containment measures brought in by most governments were necessary to slow the spread of the virus and limit the death toll, but they have also closed down business activity in many sectors and caused widespread economic hardship.
While a considerable body of literature has developed in recent years around the drivers and consequences of rural out‐migration in sub‐Saharan Africa, relatively little work has been done to understand the impacts of migration into rural areas. We use nationally representative household survey data from Zambia to explore the relationship between rural in‐migration and agricultural productivity outcomes in receiving communities. We document high levels of rural in‐migration throughout Zambia—12% of rural household heads having moved from elsewhere within the previous 10 years—with two‐thirds of rural in‐migrants originating from other rural areas. Migrants are, on average, better endowed with capital resources than their nonmigrant neighbors and are more engaged with input and output markets. After controlling for other factors, we find that higher rates of rural in‐migration are associated with greater agricultural productivity outcomes in receiving communities. These positive associations are particularly pronounced in more remote rural areas, and where in‐migration originates from other rural areas. Taken together, our results suggest that rural in‐migrants play an important role in the rural transformation processes underway in Zambia.
