Agroecological techniques: adoption of safe and sustainable agricultural practices among the smallholder farmers in Africa

Frontiers in Sustainable Food Systems, Год журнала: 2023, Номер 7

Опубликована: Май 22, 2023

Attaining sufficiency in food supply to support a growing population without compromising ecosystem functioning remains top agenda of researchers and agricultural stakeholders. Agroecological farming approaches are effective techniques that ensure sustainable production even adverse situations. Population growth has been forecasted reach over 9.1 billion by 2050 outpacing production. However, cereals grain legumes strategic achieving the United Nations Sustainable Development Goal zero hunger 2030 (SDG 2), ending extreme poverty 1), mitigating climate change effect 13). There an urgent need embrace more measures increase for population. This review explores role agroecology which employs transdisciplinary approach practices improve resilience systems increasing diversification through poly-cropping, agroforestry, use local varieties, integrated crop livestock systems. Furthermore, agroecological minimizes water use, lowers pollution levels on farm, ensures economic profitability farmers. Thus, application among smallholder farmers is ensuring security.

This paper reviews the scholarly literature discussing effect(s) of land registration on relations between tenure security and agricultural productivity. Using 85 studies, focuses regular claim that registration’s facilitation formal documents-based dealings leads to investment in a more productive agriculture. The shows this is problematic for three reasons. First, most studies offer no empirical evidence support above-mentioned effect. Second, there are suggestions can actually threaten ‘de facto’ or even lead insecurity tenure. Third, gendered realization may uneven distribution costs benefits, but these effects often ignored. Next suggesting importance information updating efficiency local management institutions, also finds research with combined locally-set approach needed better understand any relation(s)

Farmland fragmentation and defragmentation nexus: Scoping the causes, impacts, and the conditions determining its management decisions

Ecological Indicators, Год журнала: 2020, Номер 119, С. 106828 - 106828

Theoretically, both land fragmentation and consolidation (defragmentation) approaches are considered as tools of management. However, although a large literature about the relationships among fragmentation, consolidation, agriculture production crops diversification concepts exists, less is known linkages conditions determining decisions adoption these in given area. This poses major dilemmatic challenge to policy makers whether devise policies favour conservation or defragmentation. Therefore, this study identifies under which one could opt for defragmentation by critically reviewing documented causal-effects between different forms approaches. The end goal development an explicit comprehensive model indicating when, where why farmland can be preserved eliminated food security purposes within framework Sustainable Development Goals (SDGs 1, 2, 12, 13 15). Following rationalist theory, adopts integrative concept-centric qualitative approach builds on analysis existing deductive logical reasoning create new scientific knowledge topic, informative guidance future research policies. Contrary majority literature, posits that not necessarily problem. scenarios extent it becomes problematic beneficial dependent combination number local specific external circumstances, ranging from biophysical, social, economic, political, technical agro-ecological ones.

In recent decades, population growth and economic development have greatly influenced the pattern of land use/land cover (LULC) in Rwanda. Nevertheless, LULC patterns their underlying change mechanisms under future climate conditions are not well known. Therefore, it is particularly important to explore direction transfer study area, identify factors driving different types changes, simulate conditions. Based on analyses Rwanda 1990, 2000, 2010, 2015, next 30 years was simulated using an transition matrix, random forest sampling, Markov chain model, PLUS model. The results showed that area primarily comprised a decrease expansion cropland accompanied by small increase grassland annual urban area. Prior mainly converted from cropland, with ratio being 0.72:0.28. After 0.83:0.17. Changes forests, grasslands, driven multiple factors, whereas changes wetlands, water, land, unused more likely be single factor. existing trend will continue for years, exhibit which west decrease, east decrease.

Farmland Fragmentation, Farmland Consolidation and Food Security: Relationships, Research Lapses and Future Perspectives

Land, Год журнала: 2021, Номер 10(2), С. 129 - 129

Опубликована: Янв. 29, 2021

Farmland fragmentation and farmland consolidation are two sides of the same coin paradoxically viewed as management tools. While there is a vast body literature addressing connections between on one hand agriculture production crops diversification other hand, their relationship with variations in food security still under-explored. This challenges policy makers about whether how to devise policies favor conservation or defragmentation. Therefore, drawing multiple secondary data deductive logical reasoning through an integrative concept-centric qualitative approach following rationalist theory, this study critically reviews analyses existing identify versus defragmentation approaches relate security. The goal develop derive explicit model indicating when, where, why can be conserved prevented controlled for motives novel alternative comprehensive scientific knowledge generation, which could guide inform design future research management. findings show that both variously (positively negatively) impact at different (macro, meso micro) levels. highly linked (food quality), acceptability, accessibility, sovereignty local (household individual) levels, often associated quantity availability community, regional national Theoretically, best purposes achieved by minimizing problems physical tenure aspects along optimization its potential benefits. In regard, consolidation, voluntary parcel exchange on-field harvest sales, realignment, use (crop) suitable control under various conditions. Similarly, banking off-farm employment, restrictions minimum sizes subdivision absentee owners, joint ownership, cooperative farming, agricultural land protection policies, family planning measures prevent minimize problems. On intensification programs, agroecogical approaches, saving technologies most strategies maximize income from fragmented plots circumstances beneficial fragmentation. Moreover, areas where rational defective scenarios coexist, specific like localized multicropping based combination without provide better more balanced optimal solutions.
