Abstract

Food and nutrition insecurity remains a pressing challenge in many emerging economies. This study examines the heterogeneous impacts of greenhouse farming (GHF) on household food insecurity, dietary diversity, and food consumption in Ghana. Using survey data from 400 vegetable-producing households and applying marginal and policy-relevant treatment effect (MTE and PRTE) models, the analysis reveals significant heterogeneity in gains from GHF, shaped by both observable and unobservable household characteristics. Overall, GHF adoption is associated with increased dietary diversity and food consumption, as well as reduced food insecurity. The PRTE estimates indicate that improving farmers' access to produce markets could raise household dietary diversity and food consumption by 42% and 41%, respectively, while lowering food insecurity by 25%. By quantifying both the heterogeneous impacts of GHF and the role of market access, this study provides new evidence on how climate-smart agricultural technologies can enhance household nutrition and food security in sub-Saharan Africa.

采用温室农业：加纳饮食多样性、粮食消费和不安全的决定因素和影响

粮食和营养不安全仍然是许多新兴经济体面临的紧迫挑战。本研究考察了温室农业（GHF）对加纳家庭粮食不安全、饮食多样性和粮食消费的异质性影响。利用来自400个蔬菜生产家庭的调查数据，并应用边际和政策相关的处理效应（MTE和PRTE）模型，分析显示，温室气体排放的收益存在显著的异质性，受可观测和不可观测家庭特征的影响。总体而言，采用GHF与增加饮食多样性和粮食消费以及减少粮食不安全有关。PRTE的估计表明，改善农民进入农产品市场的机会可以使家庭饮食多样性和粮食消费分别提高42%和41%，同时使粮食不安全状况降低25%。通过量化温室气体排放的异质性影响和市场准入的作用，本研究为气候智慧型农业技术如何改善撒哈拉以南非洲地区的家庭营养和粮食安全提供了新的证据。

期刊介绍： Food and Energy Security seeks to publish high quality and high impact original research on agricultural crop and forest productivity to improve food and energy security. It actively seeks submissions from emerging countries with expanding agricultural research communities. Papers from China, other parts of Asia, India and South America are particularly welcome. The Editorial Board, headed by Editor-in-Chief Professor Martin Parry, is determined to make FES the leading publication in its sector and will be aiming for a top-ranking impact factor. Primary research articles should report hypothesis driven investigations that provide new insights into mechanisms and processes that determine productivity and properties for exploitation. Review articles are welcome but they must be critical in approach and provide particularly novel and far reaching insights. Food and Energy Security offers authors a forum for the discussion of the most important advances in this field and promotes an integrative approach of scientific disciplines. Papers must contribute substantially to the advancement of knowledge. Examples of areas covered in Food and Energy Security include: • Agronomy • Biotechnological Approaches • Breeding & Genetics • Climate Change • Quality and Composition • Food Crops and Bioenergy Feedstocks • Developmental, Physiology and Biochemistry • Functional Genomics • Molecular Biology • Pest and Disease Management • Post Harvest Biology • Soil Science • Systems Biology
