The potential of marginal lands to improve food security, support bioenergy production or ecosystem services has globally got a lot attention. Defining agricultural land is task that involves more than just considering the land's quality, its definition changed during last two centuries. Development new technologies and policy trends require concepts prime be renewed from time time. Although much research been done on concept land, it currently limited by lack clear, accepted definition. There are four major sources criteria lands: economic (e.g., rent cost, value), geographical temperature, slope, precipitation), ecosystem-based protected areas, recreation, services), soil suitability yield capability, physical chemical properties). categorisation into groups like productive, unproductive often depends cultivation management type. Since conceptions dynamic both in space, flexible practical solutions needed for their non-degrading use, which any case shall nature-based socioeconomic development. To maintain value these crucial develop rural areas economically biophysically marginalised. High nature farming, crops sustainable afforestation highly recommended. Choosing right can transform an optimal condition incorrect degrade (unproductive land). This paper provides review historical developments especially those working with aspects, including reclamation. It could give strong basis further topic land.

Abstract Food security depends on the ability of staple crops to tolerate new abiotic and biotic pressures. Wheat, barley, other small grains face substantial yield losses under all climate change scenarios. Intra-plot diversification is an important strategy for smallholder farmers mitigate due variable environmental conditions. While this commonly involves sowing polycultures distinct species from different botanical families in same field or multiple varieties (varietal mixtures), mixed plantings family are less well known. However, maslins, cereal mixtures, was formerly widespread Eurasia Northern Africa continues be employed by Caucasus, Greek Islands, Horn Africa, where they may represent a risk management variability. Here, we review ethnohistorical, agronomic, ecological literature maslins with focus adaptation, including two case studies Ethiopian farmers. The major points following: (1) Ethiopia, Eritrea, Georgia report that mixtures ensuring some unpredictable precipitation marginal soils; (2) experimental trials support these observations, demonstrating increased advantage stability certain conditions, making potentially adaptive practice when impacted conditions change; (3) balance trade-offs between interfamilial varietal expand total portfolio traits available formulating alone; (4) buffer against impacts trends through passive shifts composition response We demonstrate potential benefits as agroecological intensification adaptation lay out next steps outstanding questions regarding applicability cropping systems.
