“…The study about the potential use of no-tillage in Africa carried out by the German Agency for Technical Cooperation (1998) concluded that in the semiarid and arid regions of West and Southeastern Africa, different constraining factors such as (i) short growing season, (ii) low levels of biomass production, and (iii) competition for crop residues would make more viable the use of reduced tillage methods. Similarly, for semiarid West Africa, Lahmar et al (2012) concluded that it is unlikely that conservation agriculture practices, which are based on the presence of crop residues on the soil surface, will be adopted by farmers due to the competition with other residue uses.…”

“…These advantages of traditional agriculture have attracted research interests from scientists in some countries. Literature shows that conservation for traditional agriculture has been conducted by scientists across the world [16][17][18][19][20]. The Globally Important Agricultural Heritage Systems (GIAHS) launched by the Food and Agriculture Organization of the United Nations (FAO) in 2002 is an important symbol, that the international society attached importance to the protection of traditional agriculture.…”

Abstract:Heritage conservation is an important recurring research theme on agricultural heritage systems. Improving the income of farmers from agriculture is regarded as an effective conservation approach. This study examined how the improved rice-fish-duck coculture (IRFDC) promotes the protection of the Honghe Hani Rice Terraced System (HHRTS) by keeping farmers farming in their hometowns. A semi-structural interview and a questionnaire survey were used to collect data on agricultural input-outputs and household employment in HHRTS. As a result, a fairly large proportion of HHRTS rice terraces were used for the hybrid rice monoculture (HRM) with chemical inputs, and most of these rice terraces were wasted for half a year on account of being left unused; the IRFDC requires considerable time input for farming and breeding, but barely needs any chemical inputs. IRFDC entails a higher cost than HRM, but also has a higher return than HRM. Driving a family to do full-time farming requires extra more than 0.71 ha rice terraces for IRFDC. In conclusion, Globally Important Agricultural Heritage Systems (GIAHSs) can be used for protecting terraces from abandonment and destruction by improving agricultural economic benefits for farmers. At present, a shortage of laborers in HHRTS sites is false. Agricultural heritage sites do not actual need so many people if peasant households can do large-scale farming.

“…Rainfed and smallholder agriculture are the two major components of the food production system [2][3][4]. Nevertheless, inter-annual crop production variability, mainly due to the variability of the rainfall distribution and poor soil fertility, has led to chronic food insecurity [5].…”

Cropland Mapping over Sahelian and Sudanian Agrosystems: A Knowledge-Based Approach Using PROBA-V Time Series at 100-m

Abstract:Early warning systems for food security require accurate and up-to-date information on the location of major crops in order to prevent hazards. A recent systematic analysis of existing cropland maps identified priority areas for cropland mapping and highlighted a major need for the Sahelian and Sudanian agrosystems. This paper proposes a knowledge-based approach to map cropland in the Sahelian and Sudanian agrosystems that benefits from the 100-m spatial resolution of the recent PROBA-V sensor. The methodology uses five temporal features characterizing crop development throughout the vegetative season to optimize cropland discrimination. A feature importance analysis validates the efficiency of using a diversity of temporal features. The fully-automated method offers the first cropland map at 100-m using the PROBA-V sensor with an overall accuracy of 84% and an F-score for the cropland class of 74%. The improvements observed compared to existing cropland products are related to the hectometric resolution, to the methodology and to the quality of the labeling layer from which reliable training samples were automatically extracted. Classification errors are mainly explained by data availability and landscape fragmentation. Further improvements are expected with the upcoming enhanced cloud screening of the PROBA-V sensor.
