Datasets for the development of hemp (Cannabis sativa L.) as a crop for the future in tropical environments (Malaysia)

Abstract

An evidence base was developed to facilitate adoption of hemp ( Cannabis sativa L.) in tropical environments (Wimalasiri et al. (2021)). Agro-ecological requirements data of hemp were acquired from international databases and was contrasted against local climate and soil conditions using an augmented species ecological niche modeling. The outputs were then used to map the suitability for all locations for 12 possible calendar-year seasons within peninsular Malaysia. The most probable seasonal map was then used to generate a land suitability map for agricultural areas across 5 standard land suitability categories. Having developed the general suitability maps of hemp in Malaysia, detailed crop growth data were collected from literature and was then used to simulate an ideotype crop model (for both seed and fiber) for selected locations across Malaysia, where detailed daily climate data and soil information were available. Following the development of a downscaled future climate dataset, a simulated dataset of yield for the future conditions were also developed. Next, the simulated seed and fiber yield data were used to create yield maps for hemp across peninsular Malaysia. An economic value and cost-benefit analyses were also carried out using data that were collected from literature and local sources to simulate the true cost and benefit of growing hemp both for now and future conditions. This data provides the first ever evidence base for an underutilized crop in Southeast Asia. All data that was generated using the proposed published framework for the adoption of hemp in the future are stored in their original format in an online repository and is described in this article. The data can be used to map the suitability at finer scales, analyze and re-calibrate a yield model using any climate scenario and evaluate the economics of production using the standard methodology described in the above-mentioned publication.

Enviro‐economic and feasibility analysis of industrial hemp value chain: A systematic literature review

“…For example, a dual production scheme of fiber and seed in Turkey (Ceyhan et al, 2022) or a combination of concurrent products of biodiesel, fiber, or seed in Malaysia (Szulczyk & Badeeb, 2022), were seen as profitable. However, hemp fiber production only in the Turkish (Ceyhan et al, 2022) and the Malaysian edapho-climatic scenarios (Wimalasiri et al, 2021(Wimalasiri et al, , 2022 resulted in a monetary loss of −555 US$/ha and −2000 US$/ha to −1800 US$/ha, respectively. Other findings indicate that in a co-production scheme profitability could be further enhanced through biotechnological advancements that increase the amount of products with highest price, such as increasing hemp plant lipid content to enhance high-priced biodiesel production processes over ethanol production (Viswanathan et al, 2021).…”
