Located in West Africa, Senegal is classified as a least-developed country that has historically had political stability and slow economic growth compared to the rest of Sub-Saharan Africa (SSA). However, from 2012 onward, a new government has adopted new policies (infrastructure investments, liberalization of the groundnut sector and opening of the energy sector) to enhance economic growth and governance. Senegal thus experienced significant improvements in the period from 2012 to 2015. Future economic growth in Senegal can be significantly shaped by the energy sector regarding the recent oil and gas discoveries if the common resource curse can be avoided.

The country is characterized by a poverty rate of 38 percent and fairly stable food security, with only 7.2 percent of the population being food insecure. However, some localized pockets of acute food needs remain. This is in part linked to agricultural production (the main source of income and labor), which depends highly on climatic hazards. Moreover, production resources such as land are highly vulnerable to climatic and anthropogenic factors. The country has a good access rate to electricity and safe water. However, access to electricity is unequal, with rural lagging behind urban areas.

The country thus faces many challenges that threaten its economic growth: climate change and ensuring the accessibility and affordability of energy and land, which are key inputs to the main sectors of the economy such as agriculture. This report aims at investigating these interlinked challenges through a critical literature review. Results show that concerning land, its use and cover have hardly evolved over the past, except for agricultural land, which has significantly evolved from 1975 to 2013. However, the land has degraded a lot in the past several decades with up to 63-67 percent of the arable land being subject to land degradation due to climate hazards and its uses (e.g. population growth, Agro-sylvo-pastoral practices, wind and water erosion, salinization, bush fires...). Land degradation has multiple consequences, as it impacts livelihoods by limiting the availability of vital ecosystem services, increases the risk of poverty and translates into economic losses. Land degradation is estimated to cost 9 percent of the GDP annually (996 million USD).
Concerning climate change, Senegal’s climate is of the Sudano-Sahelian type, marked by the alternation of a rainy season and a dry season, whose duration varies according to the region. Rainfall and its characteristics (onset and duration) and air temperature are two factors that have changed significantly since the early 1950s and 1970s. Decreased rainfall, delayed onset of rains, reduced duration of wintering and higher temperatures have adversely affected agricultural production systems and have put some risks on food security, health and livelihoods. Projections in 2035 and 2050 will accentuate the negative impacts already observe
塞内加尔位于西非,被列为最不发达国家,与撒哈拉以南非洲其他国家(SSA)相比,塞内加尔历史上政治稳定,经济增长缓慢。然而,从2012年开始,新政府采取了新的政策(基础设施投资,花生部门的自由化和能源部门的开放)来促进经济增长和治理。因此,塞内加尔在2012年至2015年期间取得了重大进展。如果能够避免共同的资源诅咒,塞内加尔未来的经济增长可能会受到能源部门最近发现的石油和天然气的重大影响。该国的特点是贫困率为38%,粮食安全相当稳定,只有7.2%的人口处于粮食不安全状态。然而,一些局部地区仍然存在严重的粮食需求。这在一定程度上与农业生产(收入和劳动力的主要来源)有关,而农业生产高度依赖气候灾害。此外,土地等生产资源极易受到气候和人为因素的影响。这个国家的电力和安全用水普及率很高。然而,获得电力是不平等的,农村地区落后于城市地区。因此,该国面临着许多威胁其经济增长的挑战:气候变化和确保能源和土地的可及性和可负担性,这是农业等主要经济部门的关键投入。本报告旨在通过批判性文献综述调查这些相互关联的挑战。结果表明:1975 - 2013年,除农业用地变化显著外,土地利用和覆被变化不大;然而,在过去的几十年里,土地已经退化了很多,高达63- 67%的可耕地由于气候灾害及其利用(如人口增长、农林业-畜牧业、风蚀和水蚀、盐碱化、丛林火灾等)而遭受土地退化。土地退化具有多重后果,因为它通过限制重要生态系统服务的可用性来影响生计,增加贫困风险并转化为经济损失。据估计,土地退化每年造成的损失占GDP的9%(9.96亿美元)。关于气候变化,塞内加尔的气候属于苏丹-萨赫勒类型,其特点是雨季和旱季交替,旱季的持续时间因地区而异。降雨及其特征(开始和持续时间)和气温是自1950年代初和1970年代以来发生显著变化的两个因素。降雨减少、降雨延迟、越冬时间缩短和气温升高对农业生产系统产生了不利影响,并对粮食安全、健康和生计构成了一定风险。2035年和2050年的预测将加剧已经观察到的负面影响。面对这些挑战,在不同层面(家庭、社区、政策、研究等)采取了若干战略,以减少气候冲击和土地退化的负面影响。在家庭一级,战略主要包括通过汇款和非农业活动使收入来源多样化。在社区一级,组织动力得到了加强,使其能够减少妇女和儿童的脆弱性,增加获得气候信息的机会,等等。最后,政策对策主要包括塞内加尔努力制定气候变化适应和减缓计划和战略,以保护脆弱的关键部门免受气候变化的影响,并在全球一级促进减排。对关键政策、气候治理国家自主贡献计划、农业和粮食安全计划以及土地使用政策的评估突出了成功和失败的主要因素,并确定了塞内加尔政府需要密切关注的关键挑战,以确保未来政策设计和实施的更大成功。主要的挑战与治理、资金、监测和评价有关。在治理方面,重要的是确保政策的参与性设计和实施,以促进利益相关者的所有权,从而促进其含义。至于资金,关键是要避免在没有保障的资金基础上制定政策目标,而要根据已经获得的资金(如果可能的话,从国家预算中)制定切合实际的计划。最后,在监测和评价方面,关键是要确保持续提供高质量的统计数据,以便更好地确定需要干预的领域,更好地分配财政资源,更好地评估差距、进展和影响。

Many countries have a clear policy objective of increasing their share of renewable energy sources (RESs). However, a major impediment to higher RES penetration often lies in the historically grown structures of a country’s electricity sector. In Indonesia, policy makers have relied on cheap fossil fuels and state control to provide the population with access to both reliable and affordable electricity. However, this focus on only two of the three horns of the energy trilemma, namely energy security and energy equity (and not sustainability), may put Indonesia at risk of missing its ambitious RES targets. In this context, a number of small-scale reform attempts to promote RES integration in recent years have proved to be relatively unsuccessful. Like many other countries, Indonesia needs clear policy directions to avoid an unsustainable lock-in into a fossil fuel future. In the last decades, several other countries have successfully restructured their electricity sectors, for example by introducing a wholesale market for electricity under different electricity pricing systems, including nodal, zonal, or uniform pricing. These countries may hold valuable experiences of overcoming the historically grown barriers to successful RES integration through a greater role for market mechanisms. We develop three generic models that allow policy makers to analyze the impact of introducing either a nodal, a zonal, or a uniform pricing system on the three horns of the energy trilemma in their country. We evaluate our model using a simplified network representation of the Indonesian electricity sector. Our results indicate that each of the pricing systems is able to foster specific horns of the energy trilemma. Considering that any major reform intended to improve energy sustainability in Indonesia will only be a success if it also addresses energy security and energy equity, we also discuss our results from the perspective of energy justice and the need to balance the country’s energy trilemma. Ultimately, we illustrate a transformation pathway for a more sustainable and just transition to a low-carbon economy in Indonesia.
许多国家都有增加其可再生能源份额的明确政策目标。然而,提高可再生能源普及率的主要障碍往往在于一个国家电力部门历史上形成的结构。在印度尼西亚,政策制定者一直依靠廉价的化石燃料和国家控制,为民众提供可靠和负担得起的电力。然而,这种只关注能源三难困境中三个角中的两个,即能源安全和能源公平(而不是可持续性),可能会使印度尼西亚面临无法实现其雄心勃勃的可再生能源目标的风险。在这方面,近年来一些促进可再生能源一体化的小规模改革尝试被证明是相对不成功的。与许多其他国家一样,印度尼西亚需要明确的政策方向,以避免不可持续地锁定在化石燃料的未来。在过去几十年里,其他几个国家成功地改组了电力部门,例如在不同的电价制度下引入电力批发市场,包括节点、区域或统一定价。这些国家可能具有宝贵的经验,可以通过市场机制发挥更大的作用,克服历史上形成的阻碍RES成功一体化的障碍。我们开发了三个通用模型,使政策制定者能够分析引入节点定价、区域定价或统一定价体系对本国能源三难困境的影响。我们使用印度尼西亚电力部门的简化网络表示来评估我们的模型。我们的研究结果表明,每种定价系统都能够促进能源三难困境的特定角。考虑到任何旨在提高印尼能源可持续性的重大改革只有在解决能源安全和能源公平的情况下才会取得成功,我们还从能源正义和平衡该国能源三难困境的必要性的角度讨论了我们的结果。最后,我们阐述了一条印尼向低碳经济更可持续、更公正转型的转型之路。

Different types of bean cultivars are cultivated by farmers worldwide, but some of these cultivars are capable of dual-purpose cultivation with the aim of simultaneously harvesting dry grains and green pods in one growing season. So, in order to assess the possibility of dual-purpose cultivation of beans, determine the yield of green pods, dry grain yield, product value and Marginal Gross Benefit, 9 lines were evaluated in a split plot experiment based on a randomized complete block design with three replications in 2016 and 2017 in the seed and plant improvement institute, Karaj, Iran. The results showed that there was a significant difference between the lines for the studied traits. In dual-purpose cultivation of beans, line KS940144 had the highest yield (6983 kg ha-1) and value (2444 US$) of green pods. Line KS920159 had the highest yield (2068 kg ha-1) and value (2440 US$) of dry grains. In view point of the value of the product (green pods and dry grains), although the Dorsa cultivar showed the highest yield and value than dual-purpose cultivation of lines, but, because of climate change and high production risk for cultivating single-purpose cultivars, the dual-purpose cultivation of some of selected lines, for example KS940144 and KS10073 lines, could be have an appropriate income and sustainability for farmers.
世界各地的农民种植着不同类型的豆类品种,但其中一些品种能够双重种植,目的是在一个生长季节同时收获干粒和绿豆荚。因此,为了评估豆类双用途栽培的可能性,确定青荚产量、干粒产量、产品价值和边际毛效益,我们于2016年和2017年在伊朗卡拉杰种子和植物改良研究所,采用随机完全区组设计,进行了3个重复的分割小区试验,对9个品系进行了评价。结果表明,所研究性状在不同系间存在显著差异。在双重用途栽培中,品系KS940144产量最高(6983 kg ha-1),绿荚价值最高(2444美元)。品系KS920159的干粒产量最高(2068 kg hm -1),价值最高(2440美元)。从产品价值(绿豆荚和干粒)来看,虽然Dorsa品种的产量和价值高于双用途栽培品系,但由于气候变化和单用途栽培的生产风险高,部分选育品系,如KS940144和KS10073品系的双用途栽培可以为农民提供适当的收入和可持续性。

Goat raising in Thailand is not different in practices from other types of agriculture in terms of its small-scale household owned and diversity of activities. This study was conducted on 5 farmers practiced different 5 systems in Satun province, Thailand. Many farmers have built economic resilience in the agricultural farming systems under risks and uncertainties brought by changing government policies. This study seeks to examine the resilience of the economy through the scenario building in an integrated goat-other agricultural activities farming system adapted by farmers when facing external threats. This study found that the total annual margin of raising goats, with large diversity from 2.27 to 30.51 percent and in terms of cost and benefits of 5 plots in 2018 showed a gross margin of between 49,002 to 306,313 baht per year and plot 2 was an interesting farming system with higher net profits than the other plots. Since, the goat has low operation cost, it plays an important role as source of income to compensate for the lower margin when the economic crop price is low and in times when goat price is also low, farmers adjust management to reduce costs to offset lower margins. This research revealed values of economic resilience in the goat farming system which could be important to an integrated goat with other agricultural activities development.
就小规模家庭经营和活动的多样性而言,泰国的山羊饲养在实践上与其他类型的农业没有什么不同。本研究在泰国沙敦省的5名农民中进行,他们实行5种不同的制度。在政府政策变化带来的风险和不确定性下,许多农民在农业耕作系统中建立了经济韧性。本研究旨在通过在山羊与其他农业活动相结合的农业系统中构建情景来检验经济的复原力,农民在面临外部威胁时能够适应该系统。该研究发现,2018年饲养山羊的总年利润率从2.27%到30.51%不等,从5块地块的成本和效益来看,毛利率在49,002至306,313泰铢之间,地块2是一个有趣的农业系统,其净利润高于其他地块。由于山羊的经营成本较低,因此在经济作物价格较低时,山羊作为收入来源可以弥补较低的利润,而在山羊价格较低时,农民可以调整管理以降低成本以抵消较低的利润。这项研究揭示了山羊养殖系统的经济弹性价值,这可能对山羊与其他农业活动的综合发展很重要。

Analysis of the Effects and Regional Heterogeneity of Wind Energy Industry Policy in China 中国风能产业政策效果及区域异质性分析
Pub Date : 2021-01-01 DOI: 10.2139/ssrn.3880846

Subject to the dual constraints of energy and climate, wind energy has become a major development trend in the world as a renewable energy next only to hydropower. In this paper, the effects of wind energy industry policy are evaluated based on fixed-effect model, and the regional heterogeneity of wind energy industry policy is discussed based on wind resources. It is concluded that the implementation of wind energy industry policy can significantly increase wind power output without regard to the the regional differences in wind resources. In terms of the effectiveness of policy, demand-oriented policy instruments play a most important role, supply-oriented policy instruments play the second role, and environment-oriented policy instruments play the weakest role. Considering the regional differences in wind resources, the effect of the same policy varies greatly in areas with different wind resources: Supply-oriented policy instruments are slightly more effective in areas with rich wind resources, demand-oriented policy instruments are more effective in areas with poor wind resources, and environment-oriented policy instruments are significantly more effective in areas with poor wind resources.
在能源和气候的双重约束下,风能作为仅次于水电的可再生能源,已成为世界发展的一大趋势。本文基于固定效应模型对风电产业政策效果进行了评价,并基于风电资源分析了风电产业政策的区域异质性。结果表明,在不考虑风电资源区域差异的情况下,实施风能产业政策可以显著提高风电产量。在政策有效性方面,需求导向的政策工具作用最大,供给导向的政策工具作用次之,环境导向的政策工具作用最弱。考虑到风资源的区域差异,同一政策在不同风资源地区的效果差异较大:供给导向的政策工具在风资源丰富的地区略显有效,需求导向的政策工具在风资源贫乏的地区更有效,环境导向的政策工具在风资源贫乏的地区显著更有效。

Considering the regional differences in wind resources, the effect of the same policy varies greatly in areas with different wind resources: Supply-oriented policy instruments are slightly more effective in areas with rich wind resources, demand-oriented policy instruments are more effective in areas with poor wind resources, and environment-oriented policy instruments are significantly more effective in areas with poor wind resources.","PeriodicalId":7501,"journal":{"name":"Agricultural & Natural Resource Economics eJournal","volume":"14 10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79655646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Community-based Upland PalayCheck System under the Upland Rice Development Program was used as a platform of implementation. It has eight (8) KeyChecks as farmers’ best practices and technologies in upland rice production.

The study described the socio-demographic profile, institutional factors, biophysical factors, and economic factors of the farmer respondents. Moreover, it described the perceived effectiveness of Farmers’ Field School (FFS) on Upland PalayCheck System, upland community seed banking, and community-based upland palayamanan. Also, the relevance, comparability, traceability, and ease of the practice of the technologies and practices under the Upland PalayCheck System were determined. Also, respondents’ rice production practices and the percentage of adoption under the Upland PalayCheck System were assessed. Furthermore, factors that influence the level of adoption of the Upland PalayChck System were determined.

Barangay Kilig and Caragasan were selected as the locale of the study because these were the pilot site of the project in the municipality. The study was conducted through a survey questionnaire and focus group discussions. Respondents were active participants of FFS on the Upland PalayCheck System. Qualitative data were analyzed through SPSS, however, thematic analysis was done to analyzed the reasons of respondents.

The result shows that there were more female farmers in the area. Thus, the introduction of technologies should be more gender sensitive. Moreover, the majority of them were elementary level and have limited access to training except for the said FFS. These farmers were mostly owners of their land and the majority manage more than 2 ha. Thus, they need more capital in their farm operation. Also, they get their capital from cooperatives and microfinance which may bring them deep indebtedness if they do not get a good yield. Also, farming was their major source of income in the area. Therefore, they should have given other ventures in agriculture for a living. Furthermore, they get technical advice mostly from technical experts radio and leaflets. However, extension contact was only at least once a month due to the large proportion of extension workers over a number of farmers. Furthermore, the majority of the upland areas of the farmers were low soil fertility. Also, the majority of their field received low precipitation resulting in drought. Nevertheless, upland rice farming can be considered as a good alternative crop in the uplands because of its promising higher average selling price at 25.48% of premium varieties. However, seldom of them were selling their products because it is more for their food consumption. The latest average yield (2.40 t/ha) of farmer respondents was greater than the previous average yield in the municipality (>1.0/ha).

Farmers Field School (FFS) on the Upland Community-based Palayaman System was used as a platform to disseminate the objectives o
利用旱稻开发计划下的基于社区的旱稻PalayCheck系统作为实施平台。它有8个keycheck作为农民在旱稻生产中的最佳实践和技术。该研究描述了受访农民的社会人口特征、制度因素、生物物理因素和经济因素。此外,它还描述了农民田间学校(FFS)在旱地PalayCheck系统、旱地社区种子银行和基于社区的旱地palayamanan上的感知有效性。此外,还确定了Upland PalayCheck系统下的技术和实践的相关性、可比性、可追溯性和易用性。此外,还评估了应答者的水稻生产实践和在旱地PalayCheck系统下的采用率。此外,还确定了影响高地palaycheck系统采用水平的因素。基利村和卡拉加桑被选为研究地点,因为它们是该项目在该市的试点地点。该研究通过问卷调查和焦点小组讨论进行。受访者是旱地PalayCheck系统FFS的积极参与者。通过SPSS对定性数据进行分析,通过专题分析来分析受访者的原因。结果表明,该地区女性农民数量较多。因此,技术的引进应该对性别问题更加敏感。此外,他们大多数都是初级的,除了上述FFS之外,获得培训的机会有限。这些农民大多是自己土地的所有者,大多数人经营着超过2公顷的土地。因此,他们在农场经营中需要更多的资金。此外,他们从合作社和小额信贷中获得资金,如果他们不能获得良好的收益,可能会给他们带来沉重的债务。此外,农业是他们在该地区的主要收入来源。因此,他们应该在农业上从事其他的冒险活动。此外,他们主要从技术专家、广播和传单中获得技术建议。然而,由于推广人员的比例超过农民的数量,推广联系每月至少只有一次。此外,大部分农民的旱地土壤肥力较低。此外,他们的大部分田地降水少,导致干旱。然而,旱稻种植可以被认为是一种很好的替代作物,因为它的平均销售价格有望高于优质品种的25.48%。然而,他们很少出售他们的产品,因为更多的是为了他们的食品消费。答复农民的最新平均产量(2.40吨/公顷)高于该市以前的平均产量(1.0吨/公顷)。高地社区Palayaman系统的农民田间学校(FFS)被用作传播开发计划署目标的平台。还评估了农民对旱地田间FFS、CSB和旱地Palayamanan的有效性水平。结果表明,高地农民田间活动和对开发计划署的总体印象被认为是非常有效的。受访者表示,他们获得了更多的旱稻种植知识,并提高了产量。此外,他们还学会了如何解决旱稻生产中的问题。

In January-September 2020, exports of energy commodities and other minerals decreased by 36.5% (45% of the level seen in 2013) on the relevant period of the previous year. Non-oil and gas exports increased by 1.8% following a six-fold increase in gold sales. Without including gold exports, non-oil and gas exports contracted by 8.0%. A decrease in exports of energy commodities, metals, chemical products and timber was driven by an unfavorable pricing environment. Exports of high-tech goods fell by 17% because of reduction in export volumes. In January-September 2020, imports decreased by 6.9%.
2020年1月至9月,能源商品和其他矿产出口同比下降36.5%(为2013年水平的45%)。在黄金销售增长6倍之后,非石油和天然气出口增长了1.8%。不包括黄金出口,非石油和天然气出口收缩了8.0%。不利的定价环境导致能源商品、金属、化学产品和木材出口减少。由于出口量的减少,高科技产品的出口下降了17%。2020年1月至9月,进口下降6.9%。

Technology adoption has been advocated as an important way to improve agricultural productivity and welfare of farmers in the semi-arid regions across the globe. The Government of Karnataka implemented the Bhoosamrudhi program in four districts of the state (Bidar, Chikballapur, Dharwad, and Udupi) as a pilot project to increase the crop yield and income of smallholder farmers. This program was launched on the theme of technology adoption along with convergence among different departments of agriculture. Farmers have been classified into five categories based on their levels of technology intensification to assess the impact of different levels of technology intensification on their welfare. The research is built on a primary survey conducted in pilot districts of the state in 2018 over a sample of 1,465 farmer households. The results generated using econometric methods of propensity score matching (PSM) and inverse probability weighted with regression adjustment (IPWRA) highlight that the higher the intensification, the higher the net returns to the farmers. The results state that non-adopters would receive a benefit of an additional Rs.3200 per month if they adopt at least one level of technology intensification. Hence, this program turned out to be a successful model for smallholder farmers in semi-arid regions of India. Steps should be taken to maintain and expand the momentum of adoption to ensure food and livelihood security in the economy.
技术应用一直被认为是提高全球半干旱地区农业生产力和农民福利的重要途径。卡纳塔克邦政府在该邦的四个区(比达尔、奇巴拉普尔、达尔瓦德和乌杜比)实施了Bhoosamrudhi项目,作为提高小农作物产量和收入的试点项目。这个项目以技术应用为主题,以农业部门融合为主题。本文根据农民的技术集约化程度将其分为五类,以评估不同技术集约化程度对农民福利的影响。该研究是基于2018年在该州试点地区对1465户农户进行的初步调查。利用倾向得分匹配(PSM)和回归调整逆概率加权(IPWRA)的计量经济学方法得出的结果表明,集约化程度越高,农户的净收益越高。结果表明,如果非采用者采用至少一个级别的技术集约化,他们每月将获得额外的3200卢比的好处。因此,该项目成为印度半干旱地区小农的成功典范。应采取措施保持和扩大采用的势头,以确保经济中的粮食和生计安全。

In Nepal, as in many developing countries, male outmigration from rural areas is significant and is rapidly transforming the sending communities. Using primary data collected from households in rural Nepali communities, this study analyzes the effects of male out-migration from rural agricultural areas on women’s and men’s work on and off the farm. Using an instrumental variable approach to correct for endogeneity related to outmigration, the study finds differential impacts on agricultural labor for the men and women who remain. Men reduce labor in non-farm work without significantly increasing their labor allocation to other activities. Women, on the other hand, increase their work on the farm taking on new responsibilities and moving from contributing family workers to primary farmers. Despite their growing roles as primary farmers, women in households with a migrant do not increase their work in higher value activities, and remain predominantly concentrated in producing staple grains. The analysis highlights the importance of recognizing the changing roles of rural women, especially with respect to the management of the family farm, but it also raises questions about the sustainability and resilience of rural livelihoods to shocks in remittance incomes.
在尼泊尔,同许多发展中国家一样,农村地区的男性向外移徙人数很多,正在迅速改变迁出社区。本研究利用从尼泊尔农村社区家庭收集的原始数据,分析了男性从农村农业地区向外迁移对女性和男性在农场内外工作的影响。使用工具变量方法来纠正与外移相关的内生性,研究发现,留下来的男性和女性对农业劳动的影响存在差异。男性减少了非农业工作中的劳动,但没有显著增加他们在其他活动中的劳动分配。另一方面,妇女增加了她们在农场的工作,承担了新的责任,从贡献家庭的工人转变为初级农民。尽管她们作为初级农民的作用越来越大,但有移徙者的家庭中的妇女并没有增加从事高价值活动的工作,而且仍然主要集中在生产主粮上。该分析强调了认识农村妇女不断变化的作用的重要性,特别是在家庭农场管理方面,但它也提出了农村生计对汇款收入冲击的可持续性和抵御能力的问题。
