Cette revue du sous-secteur agricole du Tchad fait le point sur l'état des connaissances, les principales lacunes et les développements récents concernant les contraintes du secteur et propose des actions politiques et des leviers pour la transformation structurelle venir du secteur. Tout dlabord, la revue examine les possibilités de développement futur des chaines de valeur des cultures de rente et de base les plus importantes au Tchad.

Une réforme foncière peut concerner un ou plusieurs volets :
– la (re)définition légale des droits sur la terre, et des détenteurs de ces droits ;
– l’allocation, la privation et/ou la redistribution des droits ;
– les supports juridiques pour la reconnaissance légale de ces droits (on parle aussi d’enregistrement ou de formalisation des droits) ;
– les dispositifs administratifs et les modalités de gouvernance nécessaires à sa mise en œuvre.

Land use and land cover change (LULC) is known worldwide as a key factor of environmental modification that significantly affects natural resources. The aim of this study was to evaluate the dynamics of land use and land cover in the Matenchose watershed from the years 1991, 2003, and 2020, and future prediction of land use changes for 2050. Landsat TM for 1991, ETM+ for 2003, and Landsat-8 OLI were used for LULC classification for 2020. A supervised image sorting method exhausting a maximum likelihood classification system was used, with the application using ERDAS Imagine software.

Community-based tourism (CBT) has been adopted as an effective and practical solution to land use policies by governments that simultaneously pursue upgrading of local economy, conservation of local ecosystem and development of local communities. Confronting with new normality of detrimental eventualities in situated environments, destination management organizations (DMOs) or local governments have to employ effective governance strategies for fostering tourism community resilience in order to sustain development of CBT destinations.

Protecting cultivated land is an urgent mitigation measure for China to reconcile the contradiction between food safety and carbon neutrality. In the context of carbon neutrality, this paper constructs an evolutionary game model among local governments, agricultural technology service organizations (ATSOs), and farmers based on China’s cultivated black land, and discusses the factors influencing the strategy choice of each stakeholder group and the final form of evolutionary stabilization strategies adopted by each stakeholder from the perspective of agricultural extension.

Pricing of direct industrial real estate (DIRE) has long been under-researched due to the paucity of analysable data. Compared to other types of real estate, DIRE has often been regarded as more inefficient because of information asymmetry amongst market players stemming from a lack of market transparency. Therefore, pricing of DIRE usually does not follow a random walk and should be more predictable than other types of real estate.

Rapid urbanization results in farmland loss, habitat fragmentation, biodiversity decrease, and greenhouse gas emissions. Land-use policies and planning as administrative means are used to guide sustainable urban development and to balance the location of urban expansion and agricultural activities. To better understand the future implications of a variety of land-use policies, we used a FUTURES model scenario analysis to analyze the potential future patterns of urban areas and the loss and fragmentation of farmland and natural resources at the local level for Xi’an.

The project-based construction land-use policy of ‘increasing versus decreasing balance’ (IVDB) is pivotal to easing the contradiction between urban and rural land in China. Understanding the relationship between the scale and revenue of the balanced quota is crucial for increasing the efficiency of quota-allocated, and further improving, IVDB performance. However, existing studies have rarely revealed the impact of the balanced quota’s scale on its revenue, supported through empirical evidence.

Controlling land use change in coastal areas is one of the world’s sustainable development goals and a great challenge. Existing research includes in-depth studies of land use change in relatively developed regions, but research on economically less developed but fast-growing regions is lacking. Since the reform and opening up in Vietnam, the influences of globalization have prompted the economy of the coastal area to develop rapidly, making it one of the less developed but rapidly developing regions where human activities and global changes vigorously interact.

As an important resource for human survival and development, the utilization efficiency of cultivated land is directly related to national food security and social harmony and stability. Based on the stochastic frontier production function, this paper estimated the cultivated land use efficiency of 342 prefecture-level administrative regions in China from 2003 to 2019 and used spatial autocorrelation analysis and the Gini coefficient decomposition model to explore the spatial agglomeration and spatial disequilibrium of cultivated land use efficiency in China.

The rural land right has paved the way for the deepening of China’s agricultural land system, which is critical to the successful implementation of the rural revitalization plan in the new era. Based on the micro-survey data of farmers in Yunnan Province, we use an OLS model to empirically test the impact of rural land rights on farmers’ income in underdeveloped areas, and we use a stepwise regression method to test the mechanism role of land transfer willingness and behavior in the rural land right on farmers’ income.

The excessive use of cultivated land for non-grain production activities is considered a threat to grain security. This study presents an analysis framework on unraveling the causal mechanisms for non-grain production of cultivated land. We apply the analysis framework in Liyang, which is located in the Yangtze River Delta and is also an important “national grain base” county of China.
