<p>Sandification has become a major obstacle to China’s regional farmland protection, economic development and ecological civilization construction. Sandy land consolidation technologies and sustainable utilization modes will provide farmland for modern agricultural development. We introduced structural consolidation theory to sandy land rehabilitation from the aspects of soil body building, soil layer reconstruction and soil quality improvement. Filed experiments were conducted in Mu Us Sand Land to explore the effects of dry mixtures of guest material (red clay and loess) and sand at four volume ratios (1:1, 1:2, 1:3 and 1:5) on crop yield, soil properties and maize root growth. Red clay treatments had higher sandy land structural consolidation engineering costs and crop yields than loess treatments. Red clay and loess had significant promotion of maize and soybean yields at volume ratios of 1:3. The maximum potato yield is 42501 kg ha<sup>-1</sup> and 37332 kg ha<sup>-1</sup> in red clay treatment at volume ratio of 1:5 and in loess treatment at volume ratio of 1:5, respectively. Red clay and loess significantly increased clay and silt ratio and regulated the soil total nitrogen concentration and soil organic matter content during the critical growth stage of maize. Lowest root biomass in surface soil and lowest surface/subsoil root biomass ratio mediated maize growth in red clay treatment at volume ratio of 1:3. Red clay can be used to consolidate sandy land and develop modern agriculture in the long-term according to the engineering costs and crop yields. Enhanced land productivity, increased land transfer rent and extra wage income provide a stainable and stable increase in households’ income for escaping from poverty. Spatial overlap between red clay with sandy land makes red clay as a new available material for sand land consolidation and utilization from China to global scale. China’s sandy land structural consolidation engineering and sustainable utilization practices will contribute prescriptions to global desertification fighting and rural poverty alleviation. Regional water resource carrying capacity evaluation should be emphasized before sandy land structural consolidation engineering popularization.</p>

Sandification has become a major obstacle to China’s regional farmland protection, economic development, and ecological civilization construction. It is urgent to adopt advanced ideas and practical actions to reverse the sandy land. Structural consolidation theory was introduced to rehabilitate sandy land into farmland by soil body building, soil layer reconstruction, and soil quality improvement. A field experiment was conducted in Mu Us Sandy Land to explore the effects of blended guest materials (red clay and loess) with sand at four volume ratios (1:1, 1:2, 1:3 and 1:5) on crop yields, soil properties, and root growth. Red clay and loess significantly increased clay and silt contents and regulated the soil total nitrogen concentration and organic matter content during the critical growth stage of maize. Red clay and loess had a significant promotion of maize and soybean yields at a volume ratio of 1:3. The maximum potato yield was 42,501 and 37,332 kg ha−1 in red clay treatment at a volume ratio of 1:5 and in loess treatment at a volume ratio of 1:3, respectively. Lowest root biomass in surface soil and surface/subsoil root biomass ratio mediated maize growth in red clay treatment. Red clay was considered as the better material to rehabilitate sandy land and develop agriculture in the long-term according to the engineering costs and crop yields. Water sustainable utilization strategies and potential popularization areas of sandy land structural consolidation should be enhanced in the future.

ABSTRACT Biococotin is a fertilizer made from human feces and dried cocopit. The use of dried human feces and cocopit can be carried out on sandy land. This is because human feces are one of the feces that have good soil nutrient ability. Can be used as fertilizer on sandy land. Good plant nutrition will correlate with crop yields and farmer's income. Biococotin with manure has been used by farmers. Research carried out on sand farm farmers in Bengkulu Province discussed Lempuing Village, Bengkulu. The study was conducted for one month, June-July 2018. The process of collecting data was obtained from experimental results and interviews. Financial amount of funds needed to build and then carry out business activities. The results obtained from the costs incurred by biococtin are greater than those with manure. The entire competition meets eligibility, but nothing is feasible. This is due to high operational costs. The biggest outpouring of costs is the purchase of dry cocopit. This is because there is no dry cocopit in Bengkulu. The purchase of cocopit is carried out beyond the Bengkulu area at high prices.Keywords:  Biococotin, Finansial; Bengkulu. ABSTRAK Biococotin salah satu pupuk yang terbuat dari tinja manusia dan cocopit kering. Pemanfaatan tinja manusia kering dan cocopit dapat dilakukan di lahan berpasir. Hal ini dikarenakan tinja manusia merupakan salah satu kotoran yang memiliki kemampuan nutrisi tanah yang baik. Sehingga dapat dimanfaatkan sebagai pupuk pada lahan berpasir. Nutrisi tanaman yang baik akan berkorelasi dengan hasil tanaman dan pendapatan petani. Sehingga perlu dianalisis bagaimana perbandingan pendapatan pupuk biococotin dengan pupuk kandang yang selama ini digunakan oleh petani. Penelitian dilakukan pada petani lahan pasir di Provisi Bengkulu tepatnya Desa Lempuing, Bengkulu. Penelitian dilakukan selama satu bulan yaitu bulan juni-juli 2018. Proses pengumpulan data di dapatkan dari hasil eksperimaental dan wawancara. analisiss data aspek finansial (keuangan), jumlah dana yang dibutuhkan untuk membangun dan kemudian mengoperasikan kegiatan bisnis. Hasil yang di dapatkan yaitu biaya yang dikeluarkan biococtin lebih besar dibanding dengan pupuk kandang. Keseluruhan komoditas memenuhi kelayakan, akan tetapi komoditas kangkung perlakuan biococotin tidak layak. Hal ini disebabkan karna biaya operasional yang tingi.  Curahan biaya paling besar yaitu dalam pembelian cocopit kering. Hal ini dikarenakan tidak tersedianya cocopit kering didaerah Bengkulu. Sehingga pembelian cocopit dilakukan diluar daerah Bengkulu dengan harga mahal.Kata kunci:  Biococotin, Finansial, Bengkulu.

This study unanimously confirms that rural infrastructure is a sine qua non for significantly improving the quality of human life and phenomenally accelerating the process of agricultural development in Africa. Infrastructure projects, however, involve huge initial capital investments, long gestation periods, high incremental capital output ratio, high risk, and low rate of returns on investments. Rural infrastructure has direct and strong relationship with farmers’ access to institutional finance and markets, and increasing crop yields, thereby promoting agricultural growth. Agricultural infrastructure has the potential to transform the existing traditional agriculture or subsistence farming into a most modern, commercial and dynamic farming system in Sub Saharan Africa. Increase in investment of agricultural infrastructure leads to increase in output and employment, a full investment formulation that meets the needs of domestic or external (multilateral and bilateral) funding sources will have to be carried out. Overall, a flexible, participatory approach will be needed, with full national and local involvement and commitment, while international partners, including Food and Agricultural Organization (FAO), give initial assistance to New partnership for Africa’s Development (NEPAD) in this process. The paper therefore recommends that technical and financial assistance will be required to help build capacity in African countries to face the challenges and take full advantage of the opportunities flowing from the multilateral trading systems.

Crop planting area and spatial distribution information have important practical significance for food security, global change, and sustainable agricultural development. How to efficiently and accurately identify crops in a timely manner by remote sensing in order to determine the crop planting area and its temporal–spatial dynamic change information is a core issue of monitoring crop growth and estimating regional crop yields. Based on hundreds of relevant documents from the past 25 years, in this paper, we summarize research progress in relation to farmland vegetation identification and classification by remote sensing. The classification and identification of farmland vegetation includes classification based on vegetation index, spectral bands, multi-source data fusion, artificial intelligence learning, and drone remote sensing. Representative studies of remote sensing methods are collated, the main content of each technology is summarized, and the advantages and disadvantages of each method are analyzed. Current problems related to crop remote sensing identification are then identified and future development directions are proposed.

It’s not possible to have relied on the large irrigation programmes only to solve Maharashtra’s recurring and acute water scarcity. In recent years, the state has recognized soil and water conservation activities as a potential option for agricultural development in rainfed, semi-arid areas. Further government has clubbed all the schemes regarding soil and water conservation run by different departments of the state government under the umbrella of Jalyukt Shivar Abhiyan. The results revealed that the Jalyukt Shivar Abhiyan activities had a significant impact on groundwater recharge, access to groundwater and hence the expansion in irrigated area. It has been found to alter crop patterns, increase crop yields and crop diversification and thereby provided enhanced employment and farm income. Local villagers were at the forefront of the programme, not just in decision- making, but also in actual execution and monetary contributions. In a nutshell Jalyukt Shivar Abhiyan has not resulted in physical output but it gave support to the ecological and socio-economic progress of the beneficiaries. Looking at all the above results, Jalyukt Shivar Abhiyan seemed to be one of the basic strategy for doubling the farmer’s income in rainfed and semi-arid regions of Maharashtra

The perception of farmer’s verities, scientists and government officials regarding the conservation of bread wheat (Triticum aestivum L.) farmer in Bale zone CSBs is examined during 2019. Agricultural development and the reasons why the Bale zone is marginal in terms of wheat production are discussed. The de facto conservation of the local wheat farmer’s varieties analyzed in light of stakeholders’ opinions on agro biodiversity bread wheat conservation within the two community seed banks of Goro and Agarfa. CSBs retain local wheat farmer’s varieties because of their own interpretations of the value of these varieties. While formal opportunities for supporting farmers’ perceptions of local diversity with effective policy initiatives are available, they will require ongoing support from both international and national organizations Therefore, the objectives of this were to estimate households’ willingness to pay (WTP) value for conservation bread wheat and analyze the determining factors that affects willingness of households to participate the conservation bread wheat in the study area. To attain the stated objective contingent valuation survey questionnaires were distributed to elicit farmers WTP for improved conservation bread wheat. A total of 160 households were randomly selected from two CSBs of two Woredas of the study Zone. The result indicated that 153 (92.29%) were willing to pay the given bid amount for bread wheat conservation. Logistic regression model result was shows that the statistically significant determinants of participation of WTP in bread wheat conservation were availability of labor for farm activities, distance from market, households’ livestock holding, initial bid1 offered and productivity of the land of at 5% significance level, and total farm agricultural income and perception about the importance of bread wheat conservation at 1% level. The mean willingness to pay for the sampled respondents was 9.23 ($9. 034.67) labour day per year. Hence, the aggregate economic value of bread wheat conservation 3,098,644.46 (12,394,577.84) person days per annum for five years. Therefore, policy should give emphases at levels for production, conservation and sustainable utilization of bread wheat, farmer’s verities hence, the communities shows willingness to pay for the bread wheat conservation works.

With continuous population growth and decreasing cultivated land area, China’s food security is greatly threatened. Additionally, coal mining in China is primarily underground mining, which causes land subsidence and destroys existing cultivated land. This effect aggravates the contradiction between a growing population and a shrinking area of cultivated land. The purpose of this study was to introduce a method of filling reclamation with Yellow River sediments to restore farmland and realize the sustainable utilization of cultivated land. The properties of the soil and crop yields in reclaimed farmland were assessed. This study examined farmland reclaimed with Yellow River sediments at an experimental site located in Jining City, Shandong Province, China. Filling reclamation procedures with Yellow River sediments were applied. The reclaimed farmland (RF) and unaltered farmland (CK) were continuously monitored for three years, and the soil was sampled six times. A total of 180 soil samples were collected from RF and CK. The soil properties were measured at three depths: 0–20 cm, 20–50 cm, and 50–80 cm. Crop yields were monitored regularly. The results indicate that filling reclamation with Yellow River sediments is an effective method for restoring farmland. The RF and CK soils were weakly alkaline, non-saline soils. The RF soil was suitable for the growth of local crops. With an increasing number of farming years, both the quality of cultivated land and crop yields have increased. Therefore, filling reclamation with Yellow River sediments is an effective way to realize the sustainable utilization of cultivated land.

This paper analyzes the land use and land cover change (LUCC) of Wuliangsu Lake by interpreting Landsat5 TM images of 1987, 2000 and 2010. In the first stage (1987-2000), the area of mobile sandy land increased significantly, which signed that the environment of Wuliangsu Lake got worse. On the contrary, in the second stage (2000-2010), over 50% of mobile sandy land transformed into fixed sandy land. In addition, grassland gained a large percent from fixed sandy land and swamp. All of these changes signed that the environment of Wuliangsu Lake got better. In the two stages, the area of residential area and farmland increased obviously, large amount of grassland, swamp and fixed sandy land were converted into farmland, so we can predict that the main reason for land use changes in Wuliangsu Lake is agricultural development.

The Siwa region located in the Western Desert of Egypt has 30,000 acres available for reclamation as a part of a national project to increase agricultural production. This study addressed the climate change-driven long-term concerns of developing an agricultural project in this region where groundwater from the non-renewable Nubian Sandstone Aquifer System (NSAS) is the only source of water. Different climate models were used under two representative concentration pathways (RCPs); RCP 4.5 and RCP 8.5. Projected seasonal temperatures show that the maximum increase in summer is 1.68 ± 1.64 °C in 2060 and 4.65 ± 1.82 °C in 2100 under RCP 4.5 and RCP 8.5, respectively. The increase in water requirement for crops is estimated around 6–8.1% under RCP 4.5 while around 9.7–18.2% under RCP 8.5. Maximum reductions of strategic crop yields vary from 2.9% to 12.8% in 2060 under RCP 4.5, while from 10.4% to 27.4% in 2100 under RCP 8.5. Project goals are feasible until 2100 under RCP 4.5 but only until 2080 with RCP 8.5. When an optimization analysis was conducted, these goals are possible from 2080 to 2100 by modified land allocation. The proposed methodology is useful to project impact of climate change anywhere such that management and adaptation options can be proposed for sustainable agricultural development.
