“…The results indicated significant positive effects of SWC practices on soil water content and photosynthetic activity and that impact magnitudes were increasing over time. In another study, Shanwad et al (2008) applied satellite data to evaluate an integrated wasteland development program in India for 1997-2001 to derive the project's effects on reestablishing vegetation.…”

Development and dissemination of sustainable practices are key to enhance agricultural productivity in developing countries and to curtail potential negative externalities. Rigorous adoption/impact evaluations provide valuable lessons to enhance the capacity of agricultural research-for-development (R4D) systems in this context. Conventional evaluation studies rely solely on farmhousehold surveys for data. Generation of survey data however requires considerable financial and human capital, and the process often misses several important explanatory variables, ignores the longer-term impacts, and suffers from measurement errors. Complementary data sources are explored to make the evaluations more robust and rigorous. Here we review 54 studies that used satellite data to estimate adoption and impact of agricultural practices in developing countries. Some evidence on successful application of satellite data in high-income countries is also provided. The main findings of the paper are threefold: (1) satellite data have been successfully used to detect agricultural practices, such as cropping intensity, tillage, crop residue cover, irrigation, and soil and water conservation; (2) only a few studies have estimated the yield impacts of agricultural practices, although the estimation of crop yields with satellite data is fairly developed; and (3) only a small number of studies have explored impact estimation beyond the biophysical sphere. Estimation of certain environmental impacts of agricultural practices is possible through satellite data, although only a few studies have carried it out. Not many have assessed the economic impacts of interventions. We conclude that satellite data analysis allows information access with little delay and over longer periods, provide a unique set of variables over wide geographies, and reduce measurement error in certain variables. However, more interdisciplinary research is necessary to speed up the uptake of this alternative data source in R4D evaluations.

Precision agriculture is not for big agriculture properties only, studies have demonstrated that by using precision agricultural techniques, the increase in yields remain proportionate between large and small plots of land. Additionally, with a significant decrease of the price of technology, precision agriculture is little by little becoming affordable even to smallholder farmers. In Mexico it is urgent to apply precision agriculture techniques due to the fact the pressure for food production, and the poverty desperate situation of small farmers, although there is the pretext that the machinery and equipment used in this technology is too expensive. Information Communication Technologies (ICTs) play a key role in precision agriculture: for instance, by integrating GPS (Global Positioning System) and wireless technology into production processes, farmers are able of knowing the exact the amount of fertilizer, water, etc., needed for each portion of land, so to maximize the yield per acre, thereby exists the possibility of using smart phones in the country because there is a growth of 52.6 million smartphones in 2014. Likewise is feasible to use Unmanned Aircraft Systems (Anonymous, 2014). Since the country already exists company that manufactures the equipment so that eventually increases the usability of these increasingly larger amount. In this paper highlights that in the country there is no interest in precision agriculture, but it is possible to reverse this situation if the lines of research are promoted on the issue by the schools of mechatronics to undergraduate, master's and doctoral degrees, as they are more than 100, in support of the four schools that have precision agriculture formal courses.

“…In this context, to reduce the cost and time, satellite remote sensing has been used as an evaluation tool in many of the studies [2,3]. "Unfortunately, monitoring and evaluation have not got their share of attention and therefore has become very difficult to quantify and assess the changes made by the development programmes which have taken place in natural resources and the livelihoods of people" [4][5][6][7][8][9]. "There is not often enough room for midterm adjustments in the ongoing programmes due to the lack of a proper monitoring system.…”

“…"There is not often enough room for midterm adjustments in the ongoing programmes due to the lack of a proper monitoring system. Therefore, the need arises to identify a quick and cost-effective technique for monitoring the impact of such development programs on a 'before projectafter project' temporal scale as well as during the project implementation stage" [4][5][6][7][8][9][10]. "The Remote Sensing (RS) and Geographical Information Systems (GIS) have proven to be effective tools to monitor and manage natural resources to assess the impact of watersheds during pre-and post-development.…”

Change detection studies have been carried out for evaluation of fifteen watersheds in Anantapuramu District of Andhra Pradesh. The study was carried out using high resolution Resourcesat-2, Linear Imaging and Self Scanning-IV (LISS-IV) data of 2011 (pre-treatment) and 2016 (post-treatment) to assess the changes in land use/land cover and biomass over a period of five years (2011-16). With the implementation of the watershed developmental activities, an additional area of 14440 ha has been brought under cultivation. The output of Normalized Difference Vegetation Index classification indicates the increase in dense vegetation from 5842 ha to 13160 ha. An additional area of 396 ha increased under water bodies and 1101 ha waste land converted to cultivable land due to construction of farm ponds, percolation tanks and check dams.
