“…Poor yield is one of the main factors underlying Zambia's inability to meet the increasing rice demand through local production. On average, rice yields are 1.3 t ha −1 , which is relatively low compared to other eastern and southern African countries (ranging from 2.3 to 5.2 t ha −1 ) (Makungwe et al, 2021). Poor water management is a main factor limiting rice yields (Styger & Uphoff, 2016).…”

“…Rice production faces constant challenges due to unpredictable rainfall patterns, dry spells and drought, particularly where irrigation facilities are not available. Meanwhile, rice is the only staple crop in the country that does not meet domestic demand through local production (Makungwe et al, 2021), with the government recognizing rice as one of the priority crops on the crop diversification agenda. Under this framework, it is reasonable to think that a possible way to increase rice production could be to increase the area devoted to paddy rice linked to increasing the irrigated land.…”

To promote sustainable production and the multiple roles of paddy rice, it is essential to expand our understanding of the impacts of different management options, with particular emphasis on irrigation development. The impact of various management practices (supplementary irrigation during the rainy season, improved fertilization, cropping during the dry season and mulching practices) on irrigation water requirements, crop productivity and the multifunctional roles of irrigated paddy rice was evaluated in diverse agro‐ecological zones of Zambia, by using the AquaCrop model. Irrigation development has been demonstrated to boost paddy rice production (by 8%) in the southern districts by providing supplementary irrigation (about 150 mm) during the rainy season. Additionally, supplementary irrigation during the rainy season can make improved fertilization more attractive, doubling the yield rise under rainfed conditions. The required irrigation development would also enable paddy rice cropping intensification by allowing for dry season sowing (with net irrigation requirements from 700 to 800 mm). Moreover, the associated straw production increase could also play an important role as mulch during the dry season, reducing the net irrigation requirements by 15%. These findings will enable policymakers to make informed decisions regarding investment strategies and policies.

“…This study proposes an improved evaluation framework of "natural-non-agriculturalization sensitivity" and uses Hubei Province, a major grain-producing region in China, as the study area for farmland suitability evaluation. There has been rich research on the farmland suitability evaluation, but previous studies have mostly considered natural factors in constructing FSE framework, such as "climatic conditions-slope-soil conditions" [27] and "climatic conditions-topographic conditions-soil properties" [16], and a few studies have addressed social factors such as GDP per capita and distance from market traffic accessibility [23,24,47], but few studies have included non-agriculturalization sensitivity in the assessment. Non-agriculturalization sensitivity refers to the possibility of converting farmland agricultural use to non-agricultural use due to the influence of socio-economic factors, which have an important impact on the layout of farmland.…”

“…Farmland suitability evaluation is a process of assessment of farmland performance in order to determine whether it is suitable for cultivation [13][14][15], which can provide a key reference for decision making and the adjustment of the layout of agricultural production activities, and it is conducive to the sustainable development of farmland resources. Based on literature reviews (Table 1), it can be known that the frameworks of farmland suitability evaluation is mainly composed of natural indicators, for example: the framework of "climate-topography-soil" [16], "landform-climate-soil-location" [17], "climate-slope-soilwater [18], "soil-site" [19], "soil nutrients-location-physical and chemical properties-soil management" [20], and "climate-location-physical-chemical properties-soil nutrients" [21]. With the development of economy and society, scholars began to realize that farmland suitability is not only affected by natural factors but also disturbed by social and economic conditions to a considerable extent.…”

Farmland is one of the key factors affecting national or regional food security, and farmland suitability evaluation can provide critical information for the spatial layout of farmland. Previous studies have mainly focused on the role of natural factors in suitability evaluation, while ignoring the important influence of socio-economic activities. This study selects natural factors such as elevation and slope and non-agriculturalization sensitivity factors to build a farmland suitability evaluation framework of “natural non-agriculturalization sensitivity”, quantify the farmland suitability, and uses GIS technology to classify the evaluation results into four levels: highly, moderately, barely, and unsuitable. The results show that the non-agriculturalization sensitivity of farmland in Hubei Province shows the spatial characteristics of multi-point clustering, with density increasing from west and north to central and east; the overall farmland suitability in Hubei Province is high, and the areas of highly, moderately, barely, and unsuitable farmland account for 2.32%, 67.69%, 11.49%, and 18.50%, respectively. In terms of spatial distribution, there are obvious spatial differences in the farmland suitability, with highly and moderately suitable areas mainly distributed in the central and eastern regions and barely suitable and unsuitable areas mainly distributed in the western, northeastern, and southeastern parts of Hubei Province.

This research is motivated by the agricultural sector ranks first and plays a vital role in GRDP income in Majalengka Regency. This study aims to predict areas suitable for land use for sustainable food agriculture (LP2B) and evaluate land suitability for rice. We use the Analytical Hierarchical Process (AHP), and Geography Information System (GIS) approaches to give weight to the suitability of criteria and sub-criteria that influence multi-criteria decisions. Including using parameters; Soil morphology, elevation, rainfall, water cover, land area, disaster risk, erosion, and slope are the criteria identified as requirements for the intended application. The resulting weights to build a suitability map layer using a weighted sum overlay tool on a GIS platform by involving government stakeholders in Majalengka Regency. The results showed that the map of the evaluation of the suitability of rice production in the study area with the land was very suitable, namely 11% (15,038.49 ha) of the total study area, which was very suitable for rice production. The relationship between suitability maps and changes in spatial patterns in 2022 in the study area has also overlapped. The results showed the suitability of the spatial plan with the results of the suitability map of paddy fields.
